Abstract
This study aimed to discuss the effects of one stage surgical treatment by simultaneous osteotomy and asymmetric lengthening by Ilizarov external fixator on short femur with severe deformity of genu valgus. A total of 12 cases with unilateral deformities treated by simultaneous osteotomy and Ilizarov asymmetric lengthening on short femur with severe deformity of genu valgus were retrospectively analyzed from January 2006 to April 2015. The affected limbs were 2.5–11 cm (5.2 cm on average) short, the femorotibial angle was 135°–158° (146.3° on average), and the ankle interval was 15–43 cm (24.7 cm on average). The Paley method was used to determine the osteotomy plane (distal femur) of genu valgus. According to this standard, the bone union results were as follows: 11 had excellent and 1 had good, where 7 patients had excellent and 5 had good functional outcomes. One stage surgical treatment by simultaneous osteotomy and asymmetric lengthening on short femur with severe deformity of genu valgus was considered to be an effective and reliable method with better osteotomy union, less trauma and fewer complications.
Highlights
EF), the semi-diameter less damage to the soft tissues with maximal advantages of maintaining the bone mass, reducing the chances of nerve and blood vessel injuries, and achieving functional training earlier by a surgery
Twelve cases treated by simultaneous osteotomy and Ilizarov asymmetric lengthening on short femur with severe deformity of genu valgus from September 2009 to April 2015 were retrospectively analyzed
The staged operations were applied in traditional therapies, wherein osteotomy was applied to adjust the angular deformity, and the limb lengthening was applied after osteotomy healing for those limbs with length discrepancy[11,13] or the 8-plate was used to block the epiphyseal growth[12]
Summary
This study aimed to discuss the effects of one stage surgical treatment by simultaneous osteotomy and asymmetric lengthening by Ilizarov external fixator on short femur with severe deformity of genu valgus. In view of these results, we aimed to use Talor Frame and planned to use it in clinics soon
