Spinal tuberculosis (STB) remains prevalent in developing nations and significantly contributes to morbidity, often resulting in kyphotic deformity and neurological deficits. In this study, we correlate the diagnostic, therapeutic and prognostic factors according to the current standard of management of STB. This retrospective study evaluated diagnostic and prognostic factors in 77 patients with STB treated surgically (37.7

Introduction:Renal cell carcinoma (RCC) is notorious malignancy that could metastasize to lungs, lymph nodes, bones, and other internal organs. The spine is the most common area among bones where it metastasizes. Two main concerns for the spine surgeon regarding spinal metastasis are the stability of the spine and the prognosis of the disease. Total en bloc spondylectomy (TES) is a well-known procedure employed for the excision of metastatic lesion to the spine. Case Report:We report a case of 61-year-old elderly male with RCC with a past history of pulmonary metastasis, who presented to our institute with complaints of back pain and limited mobility in 2024. Radiological evaluation detected the lesion of the T8 vertebra. The patient underwent comprehensive evaluation with validated scoring systems (Modified Tokuhashi score of 10, and Spinal Instability Neoplastic Score of 14). Pre-operative embolization and then TES of the T8 vertebra was performed. There were no perioperative complications and he was able to mobilize post-operatively with some improvement in his neurological status. Conclusion:This case demonstrates the step-by-step approach of TES for the malignant spread of RCC to T8 vertebra with rewarding perioperative results.

Study DesignModified Delphi study.ObjectivesTelementoring, the practice of providing remote guidance and teaching from a distance using telecommunication technology, has demonstrated feasibility and value in assisting surgeons in remote locations. However, limited evidence exists regarding its effectiveness in improving surgeon performance. This study aimed to develop metrics to assess spine surgeon performance in scoliosis surgery, potentially within the context of a telementoring training program.MethodsTen expert spine surgeons participated in a four-round modified Delphi process including both online and in-person meetings. The resulting metrics were validated for objective assessment by eleven surgeons, who reviewed and rated a video recording using the established rubric.ResultsThe final set of metrics, comprising 50 procedural steps and 28 error categories, was unanimously approved by the panel. Additionally, the panel agreed that utilizing cameras, smart lenses, and output from intraoperative imaging monitors would provide sufficient visibility for assessing both steps and errors.ConclusionsA set of assessment metrics for adolescent idiopathic scoliosis surgery was successfully defined and validated by reviewing example videos. The longer-term research objective is to employ this rubric to assess surgeon's performance throughout a telementoring program, thus assessing its educational impact. The rubric could also be used in other contexts, such as live surgical observation.

Introduction:Spinal infection poses a demanding diagnostic and treatment problem for which a multidisciplinary approach with spine surgeons, radiologists, and infectious disease specialists is required. Infections are usually caused by bacterial microorganisms, although fungal infections can also occur. Most patients with spinal infections diagnosed in the early stages can be successfully managed conservatively with antibiotics, bed rest, and spinal braces. In cases of gross or pending instability, progressive neurological deficits, failure of conservative treatment, spinal abscess formation, severe symptoms indicating sepsis, and failure of previous conservative treatment, surgical treatment is required.Case presentation:A 64-year-old male presented to the Outpatient Department with a complaint of pain in bilateral upper extremities for 4 months. The pain was shooting in type, radiating to bilateral arms, forearms, and hands with no aggravating and relieving factors. He is a known case of carcinoma pyriform sinus for which he underwent various cycles of chemotherapy. Ten years later, a tracheostomy was performed for laryngeal edema, and again, an endoscopic gastrostomy was performed due to feeding difficulties. He then developed fever and cervical pain along with pain in the bilateral upper extremities. An infectious etiology was suspected for which multiple antibiotics were started with no positive response. An MRI was performed, which was suggestive of spondylodiscitis probably of tubercular origin. A biopsy was done to confirm the diagnosis, following which antitubercular (HRZE) therapy was started. He was also treated with Duloxetine and gabapentin, which resulted in minor improvements. Subsequent MRIs showed diffuse involvement of the multiple cervical vertebrae along with cord compression. Two stages of anterior corpectomy followed by posterior instrumentation were done. Following the procedure, the patient developed an infection, which was managed with antibiotics. The titanium implant was not removed. A muscle graft was planned with the pectoralis muscle and flap closure was done. The tissue was also sent for Gram stain, AFB stain, and GeneXpert, which showed normal findings. Finally, in tissue culture, Candida albicans was isolated. On performing the enzyme immunoassay test, it was found to be Aspergillus (Galactomannan antigen) positive as well. Antitubercular treatment was stopped. Then, he was managed with an antifungal, oral voriconazole, for the duration of 1 and a half years.Clinical discussion:Patients diagnosed with Candida spondylodiscitis tend to have favorable outcomes, likely linked to timely identification, thorough surgical debridement, and proper azole medication. Our case achieved success by promptly identifying and confirming it through tissue culture, detecting spinal cord compression, decompressing it, and initiating specific antifungal treatment. A delay in commencing antifungal therapy has been associated with poorer outcomes, especially in neurological health. Our patient received voriconazole for a full year, suggesting that favorable outcomes are achievable for fungal spondylodiscitis with swift and appropriate surgery and antifungal medication.Conclusion:In summary, evaluation for fungal infection is essential in all cases of unexplained spinal infection in immunocompromised patients, regardless of presentation. If the antifungal treatment proves ineffective, a surgical approach is typically employed for the management of fungal spondylodiscitis. Our report details a successful case of fungal spondylodiscitis treated with a surgical approach and highlights the potential for a fungal infection to be a causative factor in noncompressive myelopathy, which may be sometimes mistaken for radiation myelitis.

Background:Improved and efficient management of pain can certainly aid enhanced recovery after spinal surgery. Our aim is to evaluate the effect of ESPB in thoracic and lumbar surgeries where we have evaluated VAS for pain, cumulative analgesics consumptions, length of hospital stay and post-operative complications. Methods:A cross-sectional comparative study done in HAMS among the erector spinae block group and control group. The analysis of different variable was done according to standard statistical analysis. For quantitative data, univariate and multivariate analysis was performed to determine statistically significant differences using student's t-test for continuous variables. Results:60 patients were analyzed, 30 got spinae block and 30 in control group.The mean pain score for spinae block group were 1.90 ± 0.712 and 3.27 ± 1.230 for control group (p < 0.001). Cumulative mean analgesic consumption values for spinae block vs. control groups were 0.030 ± 0.042 mg vs. 0.091 ± 0.891 mg (p = 0.001) for fentanyl; 1.06E4 ± 2833.300 mg vs. 1.53E4 ± 2848.349 mg (p < 0.001) for paracetamol; 213 ± 64.656 mg vs. 494 ± 58.816 mg (p < 0.001) for ketorol; 5440.00 ± 2060.064 mg vs. 8667.50 ± 2275.006 mg (p < 0.001) for ibuprofen and 121.67 ± 31.303 mg vs. 185.00 ± 51.108 mg (p < 0.001) for tramadol. Conclusions:The ESPB technique shows early discharge from hospital and lower cumulative analgesics consumption which indicates enhanced recovery after spine surgery than control group. Improvement of pain using VAS shows immediate post-operative period recovery in those who receives spinae block.

Background A critical step in curriculum development is conducting a needs assessment of learners. In spine surgery, the educational needs of trainees, and especially of practicing surgeons, evolve frequently due to changes in practice, technology, etc. To monitor these changes and adapt the educational offerings, organizations delivering continuing medical education (CME) and continuing professional development (CPD) periodically repeat needs assessments. Methods An international needs assessment in the form of a set of 15 online questions was designed and circulated in 2017 and in 2021 to the AO Spine community of members and registered users to gather input in five main areas: educational needs in spine pathologies and techniques, required improvements in practice, preferences for types of educational offerings, and profiling information. Results We received and analyzed 1,204 responses in English during the main reporting period in the 2017 needs assessment from residents, fellows, and practicing surgeons in orthopedics and neurosurgery, and 1,845 in 2021. Spine surgeons wish to improve their knowledge related to all the common pathologies, with some variability among regions and stage of career. Minimally invasive spine surgery (MISS) was the highest-rated need within surgical techniques in all regions (except North America) and all stages of career. Data show a strong preference for face-to-face courses with hands-on training, high demand for mentorship/fellowship/observership, and solid interest in online and blended education. Conclusions The needs assessment process pointed out general trends but also identified varying needs depending on the local situation and stage of career. For this reason, CME/CPD providers must adapt to the local situation to provide educational offerings that meet learner needs.

Background Surgical site infections (SSI) in instrumented spine surgery remains as a major complication with increased morbidity. Although implementation of surgical safety checklists has been reported to lower the rates of SSI, reproducibility of these remain unclear. Objective The specific aim of this study was to explore the results of implementation of a SSI control protocol in regard to its efficacy in decreasing the rate of SSI. Methods A total of 140 instrumented spinal surgery cases between 2018 and 2021 were divided into two groups as Group 1 (checklist implemented) and Group 2 (control) and these were compared regarding SSI rates, patient rand surgery related factors, laboratory findings and infecting microorganisms. Results Ten SSIs were encountered in Group 1 (20.8%), whereas only nine in Group 2 (9.8%). Although not statistically significant (p > .05), these results highly favor the non-checklist implemented group regarding the development of SSI. A definitive infective microorganism could be identified in five out of 10 SSI in Group 1 and 6 out of nine in Group 2. Whereas only three out of 11 (27.3%) involved Gr (+) agents, rest of eight out of 11 (72.7%) involved Gr (-) agents. Discussion A failure in decreasing the SSI rate through the implementation of a SSI prevention checklist may be due to several factors pertaining to the study design, patient characteristics and the Gr (-) dominance in SSIs in our center. Nevertheless, this suggests that checklist implementation to prevent SSI in instrumented spine surgery may not be effective in all contexts.

COVID-19 pandemic created a need to improvise and redefine blended learning to be executed fully online. Background information on the effectiveness of fully online blended learning activities, especially for surgical disciplines is limited. This study describes a fully online blended learning course format on spinal surgery and aims to provide data regarding it effectiveness. Fully online blended courses on three topics of spinal surgery designed as six-week asynchronous and followed by 3-day live parts. Learning gaps (LGs) were identified with a survey at the beginning of asynchronous part, at its end, and at the end of the live part. The effectiveness of the asynchronous and live parts was assessed by LGs and a quiz, login statistics of learners and faculty and a post-course survey. Participants' LGs decreased in all courses, statistically significant in two. Faculty and learner login rates significantly correlated with each other. Faculty and learner satisfaction was very high. A fully online blended learning course can be delivered effectively on spine surgery with a high participant and faculty satisfaction rate. The asynchronous part contributes to learning significantly.

Background:The objective of this study was to determine the effect of obesity on the functional outcomes and complication rates of patients with adult spinal deformity (ASD) undergoing multi-level thoracolumbar fusion.Methods:An age and sex matched comparison of functional outcomes [Numeric Rating Scale (NRS) back and leg scores, Core Outcome Measurement Index (COMI) back scores, Scoliosis Research Society 22 (SRS22) satisfaction and total scores, Short Form 36 (SF36) general health scores, Physical Component Score (PCS), Mental Component Score (MCS), Oswestry Disability Index (ODI) (including all domains)] at 6 months, 1, 2, 3 and 4 years and the complication rates at final follow-up between obese [body mass index (BMI) >30] and normal BMI (18.5-24.9) patients undergoing more than 3 levels of thoracolumbar fusion with a minimum 2-year follow-up. Patients who had undergone any previous spinal surgery were excluded.Results:Thirty patients were included in each arm of the study. Baseline demographics, including the number of levels fused, were similar between the groups. Estimated blood loss (EBL) was higher in obese patients (1,916 vs. 1,099 mL, P=0.001), but operative time was similar (282 vs. 320 min, P=0.351). The functional outcomes and satisfaction scores were consistently poorer in the obese group at all time-points, but their satisfaction scores were similar. Obese patients had a higher complication rate (OR 3.05, P=0.038) predominantly due to dural tears and nerve root injuries, but a similar reoperation rate.Conclusions:In patients with ASD undergoing multi-level thoracolumbar fusion, obesity results in a higher blood loss, poorer sagittal correction, poorer post-operative functional scores and higher complication rates than patients with a normal BMI. However, obesity does not affect operative times, length of hospital stay or reoperation rates. Furthermore, patients with obesity have similar post-operative satisfaction scores to patients with normal BMIs.

Introduction: Malignant lymphoma (ML) can involve the central nervous system either primarily or by secondary spread, which tends to occur late in the disease as part of widespread dissemination. Lymphoma presenting as primary tumors of the spinal cord is extremely uncommon. Primary spinal lymphoma if detected early can have a good prognosis with no relapse after effective treatment. Case presentation: A 32 years old male patient presented with the symptoms of impending cauda equina syndrome which was managed with surgery and chemotherapy. The patient was successfully treated without the relapse of his condition at his 6 months follow-up scan. Discussion: Primary spinal non-Hodgkin lymphoma is a rare entity among extranodal non-Hodgkin lymphoma. MRI is usually non-confirmatory and needs immunohistochemistry for the correct diagnosis. R-CHOP regimen is the standard chemotherapy regimen. Surgical decompression is required in cases of impending neurological injury along with radiotherapy. Conclusion: Primary spinal epidural diffuse large B-cell lymphoma should be considered as a differential diagnosis in patients presenting with back pain and symptoms of impending cauda equina syndrome. It is important to early detect and treat the disease to prevent permanent neurological injury and metastasis.

To determine if responses given to each question of the Scoliosis Research Society-22 (SRS22), Oswestry disability index (ODI) and Short Form-36 (SF-36) questionnaires are influenced by the radiological parameters. Patients enrolled in a multi-centre prospectively collected adult spinal deformity database who had complete SRS22, ODI and SF-36 data at baseline and at one-year follow-up were analysed. The presence of a differential item function of each question within each score in relation to radiological parameters was analysed using a mixed Rasch model with the radiological threshold value(s) determined. Of those patients analysed (n = 1745; 1406 female, average age 51.0 ± 19.8 years), 944 were surgically and 801 were non-surgically treated. For the SRS22, questions (Q) 3, 5 and 18 were sensitive to almost all radiological parameters and the overall score was found sensitive to the Cobb angle. For the ODI, Q3, 6, 9 and 10 were not sensitive to any radiologic parameters whereas Q4 and 5 were sensitive to most. In contrast, only 3 of the SF-36 items were sensitive to radiological parameters. 78% of the SRS-22, 60% of the ODI and 8% of the questions in the SF-36 are sensitive to radiological parameters. Sagittal imbalance is independently associated with a poor overall outcome, but affects mental status and function more than pain and self-image. The assembly of questions responsive to radiological parameters may be useful in establishing a connection between changes in radiologic parameters and HRQL.

Introduction: The effect of pain on HRQoL scores in ASD patients is not well studied. Disability is a major factor on decision and outcomes. On the other hand, little is known about the effect of perceived and reported pain on these parameters, especially in the elderly population. We hypothesized that baseline back and leg pain would not affect the treatment decision whereas may have a negative effect on outcomes. Research question: To determine the correlation between preoperative ODI and VAS scores; and to identify the effect of baseline VAS score on treatment decision and ODI improvement following treatment. Material and methods: In this retrospective study, patients with a follow-up duration of minimum 2 years were enrolled from a prospective multicentric ASD database. Pearson and Spearman correlation tests were used to evaluate the correlation between ODI and VAS scores; univariate binary logistic regression method was used to analyze the effect of VAS on treatment decision as well as the outcomes. Results: 1050 patients (mean age 48.2) were analyzed. Baseline ODI and back, leg pain VAS scores were significantly correlated (P ​< ​0.001). One unit increase in baseline back and leg pain VAS scores, increased the probability of improvement in ODI by 1.219 (P ​= ​0.016) and 1.182 times (P ​= ​0.029), respectively in surgically treated patients; and reduced it by 0.894 times (P ​= ​0.012) for conservatively treated patients. For patients >70 years old, one-unit increase in baseline leg pain VAS score increased the probability of deciding on surgical treatment by 1.121 times (p ​= ​0.016). Discussion and conclusions: Preoperative back and leg pain VAS scores were found to be significantly correlated with the preoperative ODI scores. Additionally, preoperative baseline back and leg pain VAS scores were useful in predicting the improvement in disability as assessed by ODI. Another important finding was that, higher baseline leg pain (but not back pain) VAS scores increased the rate of elderly patients preferring surgical treatment.

BACKGROUND: The minimum clinically important difference (MCID), an important concept to evaluate the effectiveness of treatments, might not be a single "magical" constant for any given health-related quality of life (HRQoL) scale. Thus, we analyzed the effects of various factors on MCIDs for several HRQoL measures in an adult spinal deformity population. METHODS: Surgical and nonsurgical patients from a multicenter adult spinal deformity database who had completed pretreatment and 1-year follow-up questionnaires (Core Outcome Measures Index [COMI], Oswestry Disability Index [ODI], Medical Outcomes Study 36-item short-form questionnaire, 22-item Scoliosis Research Society Outcomes questionnaire, and an anchor question of "back health"erelated change during the previous year) were evaluated. The MCIDs for each HRQoL measure were calculated using an anchor-based method and latent class analysis for the overall population and subpopulations stratified by age, gender, and baseline scores (ODI and COMI) separately for patients with positive versus negative perceptions of change. RESULTS: Patients with a baseline ODI score of <20, 20- 40, and >40 had an MCID of 2.24, 11.35, and 26.57, respectively. Similarly, patients with a baseline COMI score of <2.75, 2.8-5.4, and >5.4 had an MCID of 0.59, 1.38, and 3.67 respectively. The overall MCID thresholds for deterioration and improvement were 0.27 and 2.62 for COMI, 2.23 and 14.31 for ODI, and 0.01 and 0.71 for 22-item Scoliosis Research Society Outcomes questionnaire, respectively. CONCLUSIONS: The results from the present study have demonstrated that MCIDs change in accordance with the baseline scores and direction of change but not by age or gender. The MCID, in its current state, should be considered a concept rather than a constant.

AIM: To determine the effect of posterior vertebral column resection (PVCR) in patients with paraplegia by using the American Spinal Injury Association (ASIA) score and Scoliosis Research Society (SRS)-22 questionnaire. MATERIAL and METHODS: Twelve patients with posttraumatic paraplegia and severe angular kyphosis (>60 degrees) had undergone PVCR between 6-24 months after the trauma for severe pain, persistent vertebral instability and difficulty in adherence to rehabilitation. ASIA scores and SRS-22 questionnaire results obtained in the preoperative and postoperative periods, and the last control were statistically compared to assess the presence of any change. RESULTS: The average age of twelve patients included in this study was 35.6 +/- 10.2 (21-51) years. Female/male ratio was 2/10 (20.0%). The mean follow-up duration was 50.3 +/- 17.6 (24-86) months. None of the patients had additional changes in neuromonitoring records during surgery. The mean preoperative kyphotic angle of the patients was 66.58 degrees +/- 7.1 degrees (60 degrees-82 degrees) which decreased to 7.0 degrees +/- 5.4 degrees in the postoperative period (p<0.05). The mean ASIA score, which was 43.3 +/- 5.1 preoperatively, increased to 44.4 +/- 4.4 in the postoperative period. The SRS-22 score, which was 2.4 +/- 0.3 in the preoperative period, increased to 4.2 +/- 0.4 in the early postoperative period. This increase was found to be statistically significant (p<0.05). The SRS-22 score was 4.1 +/- 0.4 at last follow-up and was not statistically different from the early postoperative value (p>0.05). CONCLUSION: In the light of these data, it can be stated that PVCR is a safe and reliable procedure in paraplegic patients with rigid posttraumatic kyphosis and increases patient satisfaction.

This chapter provides a summary of the applications of education via the internet, defined as 'online learning' (OL) and its advantages and disadvantages. Blended learning (BL) is a term that refers to a blend of OL and face-to-face (F2F) learning. The integration of technology into educational methods enables flexible, learner-centred learning, as well as asynchronous communication and collaboration, while providing interaction between the student and the instructor. The pace of technological change is accelerating so fast, which is bringing about many emerging opportunities in healthcare and medical education. New technologies such as machine learning, artificial intelligence, and simulations, including virtual and augmented reality, have been utilised at different levels of medical education. Minimally invasive spine surgery is one of the first application areas of the simulation-based teaching because of its steep learning curve and cost.

Abstract The results of 18 professional athletes, treated by arthroscopically assisted closed leteral capsular release for patello, femoral pathologies unresponsive to 6 months conservative treatment were prospectively analyzed. There were 10 male and 8 female patients. Mean age was 23.7 and mean follow-up was 18.4 months. The diagnosis was lateral patellar hyperpression in 7 cases, patellar subluxation in 7 cases and patello-femoral arthritis in 4 cases. After a detailed clinical and three-plane radiological assesment, the patients under went a diagnostic arthroscopy followed by a closed subcutaneous lateral release. There were no early postoperative complications. The clinical results were graded according to the scoring system of Hall. They were rated excellent in 6 and good knee 1 in lateral hyperpression group; excellent in 6 and good in 1 knee in the subluxation group; good in 1, and bad in 2 knees in the arthritis group. It was concluded that arthroscopically assisted closed lateral capsular release is a simple and effective procedure when performed in athletes who meet the indication criteria. Özet Hacettepe Üniversitesi Ortopedi Kliniği nde 1988-91 yılları arasında 6 aylık konservatif tedaviye cevap vermeyen patello-femoral patolojisi olan 18 profesyonel sporcuya artroskopik kontrol altında kapalı dış kapsüler gevşetme uygulandı. 10 erkek, 8 kadın sporcunun ortalama yaşları 23.7, ortalama izlem süresi 18.4 aydı. 7 olguya pateral patellar aşırı basınç sendromu, 7 olguya patellar subluksasyon ve 4 olguya patello-femoral artrit tanısı konmuştu. Detaylı klinik ve üç planda radyolojik değerlendirmelerden sonra hastalara tanısal artroskopi ve kapalı dış kapsüler gevşetme uygulandı. Erken post-operatif komplikasyona rastlanmadı. Sonuçlar, Hall skorlama sistemine göre değerlendirildi. Patellar sublüksasyonu olan 6 olguda çok iyi, bir olguda iyi sonuç; patellar aşırı basınç sendromu olan 6 olguda çok iyi, bir olguda iyi sonuç; patello-femoral artriti olan bir olguda iyi, bir olguda orta ve iki olguda kötü sonuç elde edildi. Endikasyon kriterlerine uyularak yapılan kapalı dış kapsüler gevşetmenin patello-femoral patolojilerin tedavisinde etkin, teknik olarak basit ve güvenilir bir yöntem olduğu sonucuna varıldı.

Study Design Retrospective cohort. Purpose This study aims to evaluate the impact of anemia on functional outcomes, health-related quality of life (HRQoL), and early hospital readmission (EHR) rates after adult spinal deformity (ASD) surgery at the time of discharge from the hospital. Overview of Literature Concerns with risks of transfusion, insufficient evidence for its benefits, and the possibility of associated adverse outcomes have led to restrictive transfusion practices. Therefore, patients are discharged according to patient blood management programs that are implemented in hospitals nationwide to reduce unnecessary blood transfusions. However, not many comprehensive kinds of studies exist on the effect of postoperative anemia on functional life and complications. Methods Anemia severity was defined following the 2011 World Health Organization guidelines. All patients had HRQoL tests as well as complete blood counts pre- and postoperatively. EHR is the admission within 30 days of discharge and was used as the dependent parameter. Results This study comprised 225 surgically treated ASD patients with a median age of 62.0 years, predominantly women (80%). Of the 225 patients, 82, 137, and six had mild, moderate, and severe anemia at the time of discharge, respectively. Seventeen of the patients (mild [11, 64.7%]; moderate [5, 29.4%]; severe [1, 5.9%]) were readmitted within 30 days. The mean hemoglobin values were higher in readmitted patients (p=0.071). Infection was the leading cause of readmission (n=12), but a low hemoglobin level was not observed in any of these patients at the time of discharge. Except for Scoliosis Research Society-22 questionnaire, HRQoL improvements did not reach statistical significance in early readmitted patients in the first year after surgery. Conclusions The results of this study demonstrated that the occurrence and the severity of postoperative anemia are not associated with EHR in surgically treated patients with ASD. The findings of the current research suggested that clinical awareness of the parameters other than postoperative anemia may be crucial. Thus, improvements in HRQoL scores were poor in early readmitted patients 1 year after surgery.

Objective To evaluate Obeid-coronal malalignment (O-CM) modifiers according to age, sagittal alignment, and patient-reported outcome measures (PROMs), in the mobile spine. Methods Retrospective review of a prospective multicenter adult spinal deformity (ASD) database with 1,243 (402 nonoperative, 841 operative) patients with no prior fusion surgery. Patients were included if they were aged over 18 years and were affected by spinal deformity defined by one of: Cobb angle ≥ 20°, pelvic tilt ≥ 25°, sagittal vertical axis ≥ 5 cm, thoracic kyphosis ≥ 60°. Patients were classified according to the O-CM classification and compared to coronally aligned patients. Multivariate analysis was performed on the relationship between PROMs and age, global tilt (GT) and coronal malalignment (CM). Results Four hundred forty-three patients had CM of more than 2 cm compared to 800 who did not. The distribution of these modifiers was correlated to age. After multivariate analysis, using age and GT as confounding factors, we found that before the age of 50 years, 2A1 patients had worse sex life and greater satisfaction than patients without CM. After 50 years of age, patients with CM (1A1, 1A2) had worse self-image and those with 2A2, 2B had worse self-image, satisfaction, and 36-item Short Form Health Survey physical function. Self-image was the consistent determinant of patients opting for surgery for all ages. Conclusion CM distribution according to O-CM modifiers is age dependent. A clear correlation between the coronal malalignment and PROMs exists when using the O-CM classification and in the mobile spine, this typically affects self-image and satisfaction. Thus, CM classified according to O-CM modifiers is correlated to PROMs and should be considered in ASD.
