Treatment of Middle-up Part Long-segment Femoral Fracture with Long Proximal Femoral Nail Antirotation.

OBJECTIVE: To investigate the outcomes of treating middle-up part long-segment fractures of the femur by long proximal femoral nail antirotation (PFNA-long). METHODS: From June 2006 to December 2013, 139 cases (35 women, 104 men; mean age 48.8, range, 18-86 years) of long-segment femoral fracture in middle-up part were treated with long proximal femoral nail antirotation (PFNA, 320-380 mm) by minimally invasive percutaneous fixation and autogenous iliac bone graft. Fifty-eight cases were graded as type IA long-segment femoral fractures (41.73%), 25 type IB (17.99%), four type IC (2.88%), 28 type II (20.14%), 12 type IIIA (8.63%), five type IIIB (3.60%), and seven type IV (5.04%). Clinical efficacy was evaluated with Harris hip function scores and postoperative pain with visual analogue scale. RESULTS: The operative time was 35-90 min (mean, 45 min) and mean intraoperative blood loss 78.6 mL (range 30-200 mL). Most patients were walking with assistance 4-10 days postoperatively. All patients were followed up for 3-37 months (mean, 19 months). There were no serious complications. All fractures healed after 2.8-6.8 months (mean, 3.9 months). According to Harris criteria, the clinical results were excellent in 108 patients, good in 22, fair in eight and poor in one. Ninety-three cases had no pain, 33 mild pain, 13 moderate pain and 25 occasionally needed non-steroidal analgesics. CONCLUSION: Closed reduction or limited open reduction with PFNA-long is an effective treatment for long-segment femoral fracture in middle-up part, with good strength in fixation, high rate of fracture union, early functional recovery and low rate of complications.

[Microsurgical one-stage repair of hand flexor tendon injuries and rehabilitation: a report of 97 cases].

OBJECTIVE: To investigate the therapeutic effects of microsurgical one-stage repair of hand flexor tendon injuries. METHODS: Among 97 patients with (182 flexor tendons) hand injuries, 59 patients were male and 38 patients were female, ranging in age from 6 to 65 years, with an average of 32 years. Twenty-two patients got injuries by glasses, 32 patients got injuries by knife, 29 patients got injuries by saw, and 14 patients got crush injuries. The tendon injuries in this study consisted of 12 cases of I zone, 35 cases of II zone, 28 cases of III zone, 8 cases of IV zone and 14 cases of V zone. Sixty-eight patients complicated with injuries of blood vessel and nerve, and 53 patients also had fingers fractures. All the patients were treated with modified Kessler method to repair tendon at one-stage, and were given early rehabilitation step by step. RESULTS: After the treatment, 97 patients were followed up from 3 to 24 months. According to TAM standard, 48 patients got an excellent result, 39 good, 8 fair and 2 bad. CONCLUSION: Microsurgical one-stage tendon repair should be applied. Early rehabilitation and microsurgery repair are important for preventing tendon adhesion.
