|Leg Length Discrepancy LLD
Leg length discrepancy (LLD) is a common problem. Leg length can be measured from anterior superior iliac spine to the medial malleolus. The Trendelenburg's test is a physical strength exam of the hip abductor, mainly gluteus medius. Other problems include hip dislocation and fracture. Two types of conditions will give rise to total hip replacement, the avascular necrosis (AVN) and osteoarthritis (OA).
