GROSS ANATOMY

Detailed explanation-1: -The primary musculature involved is the gluteal musculature, including the gluteus medius and gluteus minimus muscles. The weakness of these muscles causes drooping of the pelvis to the contralateral side while walking.

Detailed explanation-2: -Gluteus medius works to maintain the side of the pelvis that drops therefore allowing the other limb to swing forward for the next step. Gluteus medius also supports the pelvis during gait by producing rotation of hip with assistance from gluteus minimus and tensor fascia lata.

Detailed explanation-3: -Trendelenburg gait occurs when the gluteus medius is weak. Gluteus medius weakness can be the result of dysfunctions or diagnoses related to back pain or lumbopelvic pain, chronic hip dysfunctions, or lumbopelvic surgery. The weakness of the involved side causes a contralateral pelvic hip drop during swing phase.

Detailed explanation-4: -Gluteus medius pain occurs as a result of prolonged sitting or sudden bursts of repetitive activities like running or climbing. Gluteus medius is an important hip muscle that not only levels the hips but also stabilizes and balances the pelvis during activities when you balance on a single leg.
