RESUMO
OBJECTIVE: Sub-trochanteric fractures are among the most challenging for trauma surgeons. The purpose of this study was to analyze our own experience about subtrochanteric fractures. We focused on functional and radiographic outcomes after intramedullary locked nail fixation with or without cerclage assist. PATIENTS AND METHODS: A retrospective analysis on subtrochanteric fractures managed from January 2016 to April 2021 was conducted. Patients treated by closed reduction and intramedullary nail fixation were enrolled in Group A, while Group B included those patients who underwent wire-assisted intramedullary nail fixation. All patients performed clinical and radiological follow-up and complications were analyzed. The significance was established for a value of p < 0.05. RESULTS: 80 patients were included in the present study. The mean age was 74.2 (+/-19.2) years. The mean surgical time was 84.7 (+/-24.6) and 254.7 (+/-80.2) minutes in Group A and Group B, respectively. The mean blood loss was 87.3 (+/-18.3) ml in Group A and 224.4 (+/-37.8) ml in Group B. Quality of reduction was mainly superior in Group B. The mean time of union was 4.2 (+/-1.4) months in Group A and 3.4 (+/-2.1) months in Group B. Statistical differences were observed in Visual Analogue Scale (VAS) and in the Short Form 12 (SF-12) after 6 and 12 months of follow-up with better results in Group B. The complication rate was 18.2% in Group A and 12.2% in Group B. CONCLUSIONS: We recommend the use of wires when acceptable closed reduction cannot be obtained because its use may be useful for medial wall stability. For elderly patients, closed reduction may be more appropriate as the quality of life and functional recovery between the two methods is almost overlapped.
