Double Angle Varus Corrective Osteotomy in a Case of Severe Coxa Vara - A Case Report.

Introduction: The most common site of tumors is the femur in the adolescent group. As the tumour progresses in the proximal and distal metaphysis, the biomechanics of the hip and knee joints are changed, respectively. This case report is a coxa vara in an adolescent boy with fibrosis dysplasia - shepherd crook deformity, and a corrective osteotomy was done with some complications and success. Case Report: A 12-year-old adolescent came with deformity of the right thigh with shortening, and radiograph shows fibrous dysplasia with coxa vara, which was treated with corrective osteotomy and medical management. Conclusion: A proper clinical examination, pre-operative planning, finding CORA's, anticipating intra-operative difficulties, and choice of implants result in massive efficacy in terms of both decision making and results in both radiologically and functionally.
