Quality of Life Following Treatment of Trochanteric Fractures with Proximal Femoral Nail versus Cementless Bipolar Hemiarthroplasty in Elderly
Bibliographic record
Abstract
PURPOSE: There is currently no gold standard treatment for unstable intertrochanteric fractures of the elderly. Internal fixation and hemiarthroplasty are two common treatment methods but studies comparing the functional outcomes of these procedures in the elderly are limited. This study evaluates the functional outcomes of hip fracture patients treated either with internal fixation or hemiarthroplasty. METHODS: Eighty-six elderly (>60 years) patients who presented with isolated, unstable intertrochanteric fractures between 2009 and 2013 were included in the study. According to the classification of Association for Osteosynthesis/Orthopaedic Trauma Association; 12 of the patients had a 31A1.3 fracture type, 36 of the patients had 31A2.2 and 19 had 31A2.3 fracture type, 12 had 31A3.1 and seven had 31A3.3 fracture. Forty-two of 86 hip patients (Group 1) were treated with intramedullary nailing and antirotator proximal femoral nail implant (TST, Turkey), and 44 (Group 2) were treated with cementless bipolar hemiarthroplasty. Preoperative social function (Jensen) score, EQ-5D index score and mobility (Palmer/Parker) scores were obtained. Five dimensions of EQ-5D were obtained at every follow-up visit until 24 months postoperative. RESULTS: There was no statistically significant difference between two groups according to preoperative demographic variables, including mean age and sex and Jensen, Palmer/Parker,EQ-5D index, five dimensions of EQ-5D and American Society of Anesthesiologists scores. At end of 24 months follow-up, health-related quality of life had increased more in Group 1 and they reported better social functioning and mobility scores (p<0.01). CONCLUSION: Internal fixation resulted in better social functioning and mobility scores compared with cementless bipolar hemiarthroplasty at the end of 24 months in treatment of unstable pertrochanteric hip fracture in the elderly.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
