Study Notes
Hip Function and Innervation
- The superior gluteal nerve facilitates hip abduction, medial rotation, and stabilization of the pelvis during weightbearing.
- The inferior gluteal nerve innervates the gluteus maximus, which is crucial for hip extension and lateral rotation.
- The nerve to piriformis muscle derives from spinal nerves S1-S2.
- The superior clunial nerves are sourced from the posterior primary rami of spinal nerves L1-L3.
Musculoskeletal Structures and Functions
- The coccyx marks the lower boundary of the gluteal region and serves as an attachment point for multiple muscles.
- Tensor fasciae latae is innervated by the superior gluteal nerve and maintains tension in the iliotibial tract.
- The quadratus femoris and obturator internus muscles are innervated by the nerve to obturator internus.
- The superior gemellus muscle plays a role in lateral rotation of the hip joint.
Pathology and Clinical Significance
- Trochanteric bursitis results from irritation and inflammation of the bursa, characterized by deep diffuse pain in the lateral thigh area.
- A positive Trendelenburg sign manifests when the pelvis drops on the contralateral side while walking, indicating weak hip abductors.
- Gluteal gait or 'waddling' occurs when the patient leans towards the affected side to compensate for hip instability.
- Common symptoms of trochanteric bursitis include pain during activities involving hip movement and tenderness over the greater trochanter.
Miscellaneous Facts
- Bursae reduce friction in the hip region by acting as fluid-filled sacs lined by a synovial membrane.
- The gluteal muscles contribute to hip extension and facilitate abduction when the hip is flexed, supporting hip stability in the acetabulum.
- The inferior gemellus muscle assists in lateral rotation, offering support alongside the superior gemellus to stabilize the hip joint during motion.
- Spinal nerves L5-S2 contribute to innervation in the gluteal region, particularly affecting major muscle groups in hip movement.
