STUDY DESIGN:A multicenter retrospective cohort study. PURPOSE:To analyze the development of infectious complications from civilian gunshot wounds to the spine and their association with the type of prophylactic antibiotics administered and the duration of administration. OVERVIEW OF LITERATURE:Despite the risk for infections following spinal gunshot wounds, no standardized guidelines exist for their management. The limited and low-quality evidence available underscores the need for further research. METHODS:This retrospective cohort study evaluated adult civilian patients (≥18 years) treated for spinal gunshot wounds at Latin American institutions between 2014 and 2022. Demographic, clinical, and injury characteristics, treatment approaches, and infectious complications were analyzed. RESULTS:After exclusions, 292 patients, primarily adult males (n=251, 86.0%) with a mean age of 32.6 years (standard deviation=11), were included. Most injuries affected the thoracic (n=135; 46.2%) and lumbosacral (n=95; 32.5%) spine. Infectious complications occurred in 20 patients (6.8%), including spinal infections (n=3; 1.0%), non-spinal infections (n=6; 2.1%), and wound infections (n=11; 3.8%). Most patients received prolonged antibiotic prophylaxis. The median duration of antibiotic administration was significantly increased in patients with dirty wounds (p<0.001) and high-velocity injuries (p=0.001). However, the duration of antibiotic administration did not influence spinal infection rates. CONCLUSIONS:Our findings indicate a low incidence (1%) of spinal infections among patients with spinal gunshot wounds. Prolonged antibiotic use failed to reduce the risk of spinal infectious complications. Standardized guidelines for antibiotic prophylaxis in these injuries remain necessary to optimize care.
INTRODUCTION:The aim of this study was to determine the clinical and radiological outcomes of minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) compared to modified open TLIF via the Wiltse approach for treatment of degenerative diseases of the lumbosacral region. The results were evaluated over a post-operative period of 48 months. MATERIAL AND METHOD:Radiological data and medical records of patients who underwent MIS TLIF and modified open TLIF between May 2017 and May 2021 were reviewed. Parameters monitored to evaluate the surgical results were: clinical status, operation time, blood loss, radiation dose to patient, day of discharge, analgesic consumption, fusion, and complications rate. For functional assessment, the Visual Analogue Scale for back pain (VAS-BP), VAS for leg pain (VAS-LP), Oswestry Disability Index (ODI), Patient Satisfaction Rate (PSR), and the complication rate were used. RESULTS:This study included 57 patients randomly divided into two groups: 30 operated on using the MIS TLIF technique, and 27 operated on using the modified open TLIF technique via the Wiltse approach. 48-month follow-up rates were similar for the two cohorts. Patients did not differ significantly at baseline in terms of ODI, VAS-BP, or VAS-LP. Perioperatively, MIS TLIF was associated with significantly less blood loss (167.3 ± 80.0 vs. 297.9 ± 81.5 ml, p = 1.1E-05), slightly longer procedures (185.7 ± 45.2 vs. 183.1 ± 66.4 minutes, p = 0.76), a lower radiation dose (MIS 16.9 ± 7.1 vs. 22.0 ± 9.7 mGy OPEN p = 0.012), and shorter hospitalisations (MIS 5.9 ± 1.8 vs. 7.7 ± 1.6 days OPEN). The most common complication was radiculitis, which accounted for 33% and 37% in the MIS and the TLIF groups, respectively. The second most common complication was malposition of the fixation material, which accounted for 18.5% in the TLIF group and 20% in the MIS group. The level of fusion achieved was 92.6% in the MIS group versus 92.3% in the TLIF group. There was lower consumption of analgesics in MIS. Patient Satisfaction Rate (PSR) was 90%. CONCLUSIONS:Clinical and radiological outcomes after MIS TLIF in patients with degenerative disease of the lumbosacral region are generally favourable. MIS TLIF was associated with decreased blood loss perioperatively, a lower radiation dose and an earlier discharge, but there was no difference between MIS TLIF and modified open TLIF in 48-month outcomes in terms of disability, back pain, leg pain, quality of life, or patient satisfaction rate or complication rate. Although the differences taper off over time, MIS TLIF has undeniable advantages in the perioperative and early postoperative periods.
Holistic integrative medicine, abbreviated as HIM, has been officially proposed since 2012. Its theoretical system has been continuously improved, and its practical methods have become increasingly diverse, becoming an inevitable choice and path for the medical development in the new era. This article demonstrates ten major propositions for HIM, elaborating on the connotation and extension of HIM from the perspectives of epistemology and methodology, in order to achieve the transformation and adaptive evolution of modern medicine.
ABSTRACT Introduction A light-weight pneumatic-powered knee exoskeleton could augment mobility and lifting capabilities for a variety of occupational settings. However, added weight/bulkiness and artificially produced knee extension torque could compromise sensorimotor characteristics. Materials and Methods Ten healthy participants conducted 3 visits within 10 days to the biomechanics laboratory. Participants were asked to complete the following tasks on each visit: single-leg balance, single-leg drop-landing, and select functional movement tasks. Balance characteristics (the ground reaction forces variability and center-of-pressure velocity) were derived from force plates while knee flexion angles during drop-landing and functional movement tasks were captured using a motion capture system. Descriptive statistics as well as paired t-tests or Wilcoxon signed-rank tests were used to compare between conditions. Significance was set at P < .05 a priori. Results During single-leg balance, the ground reaction force variabilities were significantly increased (P = .013–.019) and the center of pressure velocity was decreased (P = .001–.017) when wearing knee exoskeleton. During single-leg drop-landing, the exoskeleton condition showed lower knee flexion angles at the initial contact (P = .004–.021) and peak (P = .006–.010). Additionally, the peak vertical ground reaction force was higher in the exoskeleton condition (P = .007). During functional movement tasks, the exoskeleton condition showed less knee flexion range-of-motion during the overhead squat (P = .007–.033) and hurdle step-over (P = .004–.005). Conclusions Participants exhibited stiffer landing technique with the exoskeleton. Given that these compromised sensorimotor characteristics have been associated with musculoskeletal injury risk, modifications to exoskeletons to promote softer landing and greater knee flexion range-of-motion during dynamic activities may be warranted.
