Subtrochanteric femur fracture treated by intramedullary fixation / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>To discuss surgical technique, operative efficacy and clinical outcome of intramedullary fixation in the treatment of subtrochanteric femur fractures.</p><p><b>METHODS</b>From February 2011 to February 2013, 76 cases of subtrochanteric femur fractures were treated by intramedullary fixation in our hospital, including 53 males and 23 females, with the age range of 37 -72 years (mean 53.5 years). According to Seinsheimer classification, there were 2 cases of type I, 7 type II, 15 type III, 23 type IV and 29 type V. Firstly, all patients underwent closed reduction with the guidance of C-arm fluoroscopy in a traction table. Two cases of type I and 3 cases of type III fractures had ideal closed reduction followed by internal fixation. The others needed additional limited open reduction. Radiographic examination was used to evaluate callus formation and fracture healing in postoperative 1, 3, 6 and 12 months follow-up. Functional recovery was evaluated by Harris Hip Scoring (HHS) system.</p><p><b>RESULTS</b>Patients were followed up for 6-12 months. All fractures were healed except one patient with delayed union. The average bone union time was 4.5 months. According to HHS system, 65 cases were considered as excellent in functional recovery, 8 good, 2 fair and 1 poor. The proportion of the patients with excellent and good recovery was 96.05%.</p><p><b>CONCLUSION</b>Intramedullary fixation is feasible for the treatment of subtrochanteric femur fracture. The accuracy of intraoperative reduction and surgical skill are important for the clinical outcome and the patients' prognosis.</p>

Case-control study on locking plates fixation for the treatment of Neer 3-and 4-part proximal humerus fractures / 中国骨伤

<p><b>OBJECTIVE</b>To compare therapeutic effects of locking plates for the treatment of Neer 3-and 4-part proximal humerus fractures.</p><p><b>METHODS</b>From January 2009 to June 2011, 64 patients with Neer 3-and 4-part proximal humerus fractures were treated with locked plate fixation. There were 39 patients in the 3-part group including 16 males and 23 females, with an average age of (55.12 +/- 12.52) years old; and 25 patients in the 4-part fractures group including 9 males and 16 females,with an average age of (57.92 +/- 13.14) years old. The American Shoulder and Elbow Surgeons score (ASES), visual analogue scale (VAS) and complications were documented for analysis before and after treatment.</p><p><b>RESULTS</b>All the patients had incision healing at the first stage. All the patients were followed up, and the duration ranged from 12 to 30 months, with a mean of 16.5 months. Comparably better shoulder function recovery was achieved in the 3-part fractures group with regard to the ASES (76.14 +/- 14.10 in the 3-part fractures group vs. 65.93 +/- 11.82 in the 4-part fractures group, P < 0.05). Moreover,a statistical difference (P < 0.05) was observed regarding the VAS pain score (2.12 +/- 1.63 in the 3-part fractures group vs. 3.90 +/- 2.21 in the 4-part fractures group). For the complications rate,no statistical difference was noted between 3-part fractures group and 4-part fractures group (20.51% vs. 36.00%).</p><p><b>CONCLUSION</b>The clinical outcomes of the 3-part proximal humerus fractures is better than the 4-part fractures proximal humerus fractures treated with locking plate. Complex proximal humeral fractures treated with locking plates can be achieved a satisfactory outcome when attention is paid to anatomic reduction, stable fixation, proper screws and plate placement, and reasonable functional exercise postoperative.</p>
