Final answer:
Treatment for varus femoral neck non-union typically involves surgical options like open reduction and internal fixation or hip replacement to restore proper hip function and prevent potential complications like avascular necrosis.
Step-by-step explanation:
The question concerns the treatment of varus femoral neck non-union, which is a medical condition related to the hips and often involves an orthopedic intervention. The femoral neck is part of the thigh bone that could suffer a fracture. A potential consequence of a femoral neck fracture within the capsule of the hip joint includes the disruption of the vascular supply to the head of the femur, which may lead to avascular necrosis (bone death due to lack of blood supply). Management of varus femoral neck non-union typically includes surgical intervention to repair the fracture and restore proper alignment and stability to the hip joint. Options may include open reduction and internal fixation (ORIF), hip replacement, or osteotomy. Each case requires evaluation by an orthopedic specialist to determine the most appropriate treatment strategy.
