The PFNA Nail for Pertrochanteric Fracture of the Femur without Fracture Table

PURPOSE: The purpose of this study is to analyze the results of intertrochanteric fractures treatment with proximal femoral nail antirotation (PFNA) without using fracture tables and thereby prevent complications. MATERIALS AND METHODS: Forty cases of intertrochanteric fracture of 39 patients that were treated with PFNA without using fracture tables between January 2008 to December 2009 were analyzed. There were 13 males and 27 females. The mean age was 76 years old. Using AO classification, 6 cases were A1, 25 cases were A2 and 9 cases were A3. The operation was done without using fracture tables at supine position. Operation time, intraoperative bleeding were checked. For the result, Cleveland index, tip apex distance, fracture site sliding rate, change of femur neck and shaft angle were evaluated. Bone union time and complications were also estimated from the follow up radiograph. Statistics were analyzed using Independent T-test. RESULTS: The mean operation time was 40 minutes (25 to 70 minutes) and mean intraoperative bleeding was 113 cc (40 to 250 cc). The Cleveland index was shown 94% of 5, 6, 8 and 9 zone, the tip apex distance was 12.96 mm (6 to 22 mm), the fracture sliding distance was 1.9 mm (0 to 6 mm), the change of femur neck and shaft angle was 2.5 degree (0~10 degree) and the average bone union time was 15 weeks (8 to 24 weeks). The complication include 2 cases of delayed union and 2 cases of varus deformities. CONCLUSION: We have shortened the operation time by closed reduction methods without using the fracture tables, and the complication were minimized with using simple tools like a reduction forcep or bone hook at PFNA blade insertion.

Treatment of Traumatic Posterior Fracture and Dislocation of the Hip

Purpose: To evaluate outcomes and complications after traumatic posterior hip fractures and dislocations classified according to the Thompson-Epstein system. Materials and Methods: Thirty-five cases were selected from among the patients we treated between January 2000 and December 2005. According to Thompson-Epstein classification, 5 cases were type I, 7 cases were type II, 5 cases were type III, 8 cases were type IV, and 10 cases were type V. The mean age at the time of injury was 41 years (range: 19~72 years). Twenty-six patients were men, and 9 patients were women. The mechanisms of injury included traffic accidents in 30 cases and falls in 5 cases. The mean follow-up period was 31 months (range: 13~86 months). Fracture reduction was achieved within 6 hours in 32 cases. Thirty-four patients underwent closed reduction, and 22 of these patients were treated using Allis'method. Results: All Thompson-Epstein type I fractures were managed with closed reduction. Two type II fractures were treated conservatively, and 4 were treated with open reduction and internal fixation. All 13 type III and IV fractures were treated using open reduction and internal fixation. Six type V fractures were treated conservatively, 4 were treated with open reduction and internal fixation, and 1 was treated using total hip arthroplasty. Posttraumatic arthritis was observed in 9 cases, 7 of which were Thompson-Epstein type IV. Avascular necrosis (AVN) of the femoral head and deep vein thrombosis were observed in 1 case. Sciatic nerve injury was seen in 5 cases. Conclusion: Complications often occur in Thompson-Epstein type IV fractures. We believe that early, appropriate anatomical reduction helps to improve outcomes.

Treatment of Femoral Head Fracture with Traumatic Posterior Dislocation of the Hip

PUEPOSE: To evaluate the treatment results and complication of a femoral head fracture with posterior dislocation of the hip according to the Pipkin classification. MATERIALS AND METHODS: Ten cases of Thompson-Epstein type V femoral head fracture with a posterior dislocation of the hip were evaluated. According to the Pipkin classification, 5 cases were type I, 1 case was type III, and 4 cases were type IV. The average age at time of trauma was 38 (19~72) years, and the causes were traffic accidents in 9 cases and falls in 1 case. The average follow-up period was 33 (13~79) months. A reduction of the fracture was performed within 6 hours in 9 cases and 12 hours in 1 case. When the stability was achieved after the reduction, the choice of further treatment was made from either conservative treatment while maintaining skeletal traction, or surgical treatment according to the fracture type and instability. The complications were evaluated by a physical examination, simple radiography, computed tomography (CT) and magnetic resonance imaging (MRI). RESULTS: In Pipkin type I fractures, 4 cases were treated with conservative treatment and 1 case was treated with surgical treatment. One case of Pipkin type III fracture was treated with primary total hip arthroplasty. In Pipkin type IV fractures, 2 cases were treated surgically using a plate and 2 cases were treated with conservative treatment with skeletal traction. Bone union was achieved in all cases. One case of mild posttraumatic arthritis and 1 case of avascular necrosis was found, respectively in Pipkin type IV. CONCLUSION: The extent of the initial injury has an effect on the prognosis of a hip fracture and dislocation.
