PURPOSE
This study evaluated the shortening and rotational deformity after closed intramedullary nailing of femur shaft fracture according to Winquist-Hansen classification type.
MATERIALS AND METHODS
This study was based on 98 cases who received cloased intramedullary fixation about their femur shaft fractures between January 2000 and October 2005 with minimum 12 months follow up. The rotational deformity was analysed by Yang's method (45 cases) preoperatively and postoperatively, and the shortening by orthoradiogram (55 cases). Furthermore we analysed other complications, for example nonunion, infection, and metal failure.
RESULTS
We found more than 15 degrees anteversion difference of both femurs in 10 cases. Among them, 9 cases were classified to type 3, 4. According to Winquist-Hansen classification, rotational deformity ranged from 3.7° (Type 1) to 8.9° (Type 4). More than 2 cm leg length discrepancy (LLD) was found in 9 cases, all of them were classified as Winquist-Hansen classification type 3, 4. In the type 1, LLD was checked as 3.2 mm and type 4, 14.2 mm.
CONCLUSION
To prevent the shortening and rotational deformity after intramedullary fixation of Winquist-Hansen classification type 3, 4 femur shaft fracture, intraoperatively the exact contralateral femoral anteversion and length should be checked.
