Trendelenburg's sign is found in people with weak or paralyzed abductor muscles of the hip, namely gluteus medius and gluteus minimus. [1] It is named after the German surgeon Friedrich Trendelenburg. It is often incorrectly referenced as the Trendelenburg test which is a test for vascular insufficiency in the lower extremities.
Outer hip pain might be caused by one of the gluteal muscles in the hip or tightness in the long band of connective tissue that runs down the leg, called the iliotibial (IT) band.
The most impaired movement pattern of hip abduction is when the quadratus lumborum initiates the movement, which results in hip hiking during swing phase of gait. Hip hiking places excessive side-bending compressive stresses on the lumbar segments. Thus, a tight quadratus lumborum may be another hidden cause of low back pain (Janda 1987).
Trendelenburg gait is caused by weakness or ineffective action of the abductor muscles of the lower limb, the gluteus medius muscle and the gluteus minimus muscle. [4]Damage to the motor nerve supply of the lateral gluteal muscles (gluteus medius muscle and gluteus minimus muscle)
Other causes of trochanteric bursitis include uneven leg length, iliotibial band syndrome, and weakness of the hip abductor muscles. [1] Greater trochanteric pain syndrome can remain incorrectly diagnosed for years, because it shares the same pattern of pain with many other musculoskeletal conditions.
According to the Cleveland Clinic, piriformis syndrome causes pain or numbness in a person’s butt, hip or leg. The pain typically occurs when the body’s piriformis muscle presses on the ...
Muscles and ligaments surround and attach to the SI joint in the front and back, primarily on the ilial or sacral surfaces. These can all be a source of pain and inflammation if the SI joint is dysfunctional. [9] [2] The sacroiliac joint is highly dependent on its strong ligamentous structure for support and stability. [9]
The gluteal muscles can be classified into two main groups: The superficial gluteal muscles are responsible for extension and abduction of the hip as well as stabilizing and maintaining the balance of the pelvis during the gait cycle. Deep gluteal muscles control external rotation of the extended hip and abduction of the flexed hip. [2]
