Marked varus deformity due to insufficiency fracture of the proximal tibia treated by open-wedge high tibial osteotomy: a case report

摘要

Introduction: Insufficiency fractures occur most commonly in the pelvic girdle and the sacrum, followed by the tibia and the femoral neck. Because insufficiency fractures are often treated conservatively with rest, immobilization with cast or braces, anti-inflammatory analgesic agents, and reduced activity, surgery is rarely indicated, except in patients with marked deformity, those in whom bone union is not achieved, and those with mamnion. For this reason, few studies have reported surgery for insufficiency fracture of the proximal tibia [1-3]. In our case, marked varus deformity occurred in a short period, markedly interfering with gait and indicating a need for surgery. To our knowledge, no previous case report has discussed corrective open-wedge osteotomy as the primary surgery in patients with insufficiency fracture of the proximal tibia.
