Correction of genu valgum deformity with femoral translation osteotomy and antegrade interlocking nail

Introduction: Genu valgum is a common deformity which is treated by almost every orthopedic surgeon. There are various methods to treat this deformity with usually satisfactory results. In adults, a femoral osteotomy is the most used method of correction of deformity. It is usually fixed by a plate. A large skin incision is required. The patient is usually kept non-weight bearing for a varying period. We present a technique in which a minimally invasive percutaneous osteotomy is performed and fixed with an antegrade interlocking nail. The implant used is familiar, readily available, and cost-effective. Weight-bearing is started immediately, and no immobilization is necessary. Materials and Methods: We analyzed 22 cases of genu valgum treated with this osteotomy in a single center. We performed the percutaneous osteotomy and fixation with antegrade interlocking intramedullary nail. All patients were allowed to walk with a walker and full weight bearing from the next day as pain permitted. Every patient was called for follow-up at 1, 3, and 6 months. At every follow-up, orthogonal X-rays were taken, and the range of motion (ROM) at the knee and hip was recorded. Results: All 22 cases showed good union at the osteotomy site and full knee and hip ROM at 6 months. We had no wound complications or limb length discrepancy in any case. Conclusion: This technique is a useful tool to add to the orthopedic surgeon’s armamentarium. It is a cost-effective and minimally invasive solution to a very common problem, using familiar implants. A comparative study is warranted to study its superiority to other techniques. Keywords: Genu valgum, Interlocking nail, Osteotomy, Minimally invasive.
