The definition of jumbo acetabular cups for revision total hip arthroplasty (THA) is predominantly based on Western populations, with limited applicability to ethnic variations. Indian patients often exhibit distinct anatomical characteristics, necessitating population-specific guidelines to avoid complications such as excessive bone loss or suboptimal component fixation. This study aimed to establish jumbo cup dimensions for Indian patients and compare these findings with global standards. This retrospective, multicenter observational study analyzed data from 2,372 primary THA patients across four high-volume orthopedic centers in India (2010–2023). Patient demographics, etiology, and acetabular component sizes were extracted from institutional registries. The jumbo cup was defined as 10 mm larger than the mean acetabular component size. Statistical analyses, including one-way ANOVA and linear regression, were conducted to assess the influence of demographic and etiological factors on cup size. The mean acetabular cup size was 49.99 mm (SD: 3.51). Male patients required significantly larger components (mean: 51.23 mm) compared to females (mean: 47.21 mm, p < 0.001). Based on the jumbo cup definition, thresholds were proposed as 62 mm for men and 58 mm for women. These dimensions are 2–4 mm smaller than those recommended for Western populations. Etiology-specific differences were observed, with post-acetabular fractures requiring the largest cups (mean: 2.08 mm increase, p < 0.001). This study highlights the need for ethnic-specific jumbo cup definitions in revision THA. The proposed dimensions for Indian patients provide a practical framework for preoperative planning, emphasizing the importance of personalized surgical strategies to enhance outcomes and reduce complications.

Foreign body ingestion in adults, particularly an electronic device containing a lithium-based battery, remains a challenging emergency department (ED) presentation, due to limited literature and specific guidelines. Management decisions depend on object characteristics, anatomical location, and symptomatology. We report the unusual case of an alert, 22-year-old female who accidentally ingested a single wireless earbud. On presentation to the ED within an hour of ingestion, she remained asymptomatic with stable vital signs throughout evaluation. An initial erect abdominal radiograph localized the foreign body to the second part of the duodenum. Following multidisciplinary discussion, a conservative "wait-and-watch" approach was adopted. Serial abdominal radiographs demonstrated gradual distal migration, confirming spontaneous passage of the device on day five. This case highlights the importance of individualized risk assessment and underscores the role of conservative management with close radiologic monitoring in selected asymptomatic patients, even when the ingested object is an electronic device containing a sealed lithium-ion battery.
Abstract Background Femoral neck anteversion (FNA) is a key determinant of hip biomechanics and component positioning in total hip arthroplasty (THA). Most reference values for femoral version are derived from Western populations and non-robotic measurement techniques. Data defining native femoral version in the Indian population using CT-based robotic planning are limited. Methods This multicenter cross-sectional study analyzed 742 hips undergoing primary robotic-assisted THA using the MAKO THA 4.0 system. Native femoral version was calculated automatically from preoperative CT scans as the angle between the femoral neck axis and the trans-epicondylar axis. Femoral version was categorized as retroversion (< 0°), neutral (0°), or anteversion (> 0°). Descriptive statistics were reported as Mean (SD). Group comparisons were performed using chi-square tests, with statistical significance set at p < 0.05. Results The mean native femoral version was − 2.6° (SD 11.9), with a range from − 42° to 41°. Overall, 395 hips (53.2%) demonstrated retroversion, 320 hips (43.1%) anteversion, and 27 hips (3.6%) neutral alignment. Retroversion predominated in males, whereas females showed significantly higher anteversion ( p < 0.001). No statistically significant differences were observed across age groups ( p = 0.310; Spearman ρ = 0.034, p = 0.356) or diagnosis categories ( p = 0.227). Notably, 703 hips (94.7%) demonstrated femoral version below 15°. Conclusion Indian patients undergoing THA demonstrate substantially lower femoral neck anteversion than commonly cited Western norms, with more than half exhibiting femoral retroversion. These findings highlight the importance of population-specific and individualized preoperative planning, for which CT-based assessment can be useful.
Langerhans Cell Histiocytosis (LCH) is a haematological malignancy characterized by the clonal Langerhans cells proliferation. There is paucity of data on adult patients with LCH in India. We reviewed 18 patients of Adult Non-Pulmonary LCH treated at our institute from 2019 to 2024. Their Clinico-pathological features, treatment given and survival were studied. Median age at diagnosis was 30 years. 61
