Abstract:
Objective To investigate the effects of long proximal femoral nail antirotation (PFNA-long) in treating long-segment fracture in middle-up part of femoral. Methods From June 2006 to December 2013, we treated 139 cases long-segment fracture in middle-up part of femoral with long proximal femoral nail antirotation (PFNA, 320-380 mm) by minimally invasive per-cutaneous fixation and autogenous iliac bone graft. Data of 139 patients (104 male and female 35;ages 18 to 86 years, with an aver-age age of 48.8 years). Type IA 58 cases (41.73%, 58/139), type IB 25 cases (17.99%, 25/139), type IC 4 cases (2.88%, 4/139), type II 28 cases (20.14%, 28/139), type IIIA 12 cases (8.63%, 12/139), type IIIB in 5 cases (3.60%, 5/139), type IV 7 cases (5.04%, 7/139). The duration from injury to surgery was 3 hours to 12 days, with an average of 4.2 days. The postoperative follow-up was at 1, 2, 3, 6, 9, 12 months, and annually at least. The clinical efficacy was evaluated with Harris hip function score. The postoperative pain was evaluated with visual analogue scale (VAS). Results The operative time of 139 cases was from 35 to 90 minutes, averaged 45 minutes and the blood loss during surgery averaged 78.6 ml (ranged from 30 to 200 ml). All patients walked by walking aid appliance after 4 to 10 days postoperatively, apart from 16 cases with serious long grinding fracture. All patients had been followed up for 3 to 37 months (mean 19 months). No complications, such as infection, lower limb vein infarction, cut-out and breakage of the implants, occurred. However, there were 4 patients with nail broken and 6 patients with hip internal rotation who were treated by secondary operation. There were 5 cases with slight hip external rotation and 8 cases with hip internal reverse-lamb shortening malformation. All fractures healed after 2.8-6.8 months (mean 3.9 months). According to Harris criteria, the clini-cal results were best in 108 cases, better in 22 cases, good in 8 cases, and bad in 1 case. The excellent and good rate was 93.53%(130/139). The score for VAS was 0-6 (mean 0.8), 93 cases in which no pain, mild pain in 33 cases, moderate pain in 13 cases, 25 cases occasionally need to take non-steroidal analgesics. Conclusion Closed reduction or limited open reduction with PFNA-long is an effective treatment for long-segment fracture in middle-up part of femoral, with higher strength in fixation, higher rate of fracture union, early functional recovery and lower rate of complications.
