Study Notes
Hip Joint Overview
- The hip joint is a synovial ball-and-socket joint.
- The joint is formed by the hemispherical head of the femur and the cup-shaped acetabulum of the hip bone.
- The acetabulum's articular surface is horseshoe-shaped and incomplete inferiorly at the acetabular notch.
Hip Joint Articulation
- The acetabulum has a fibrocartilaginous rim, the acetabular labrum, deepening the socket.
- The labrum extends across the acetabular notch and is referred to as the transverse acetabular ligament.
- The articular surfaces of the joint are covered with hyaline cartilage.
Hip Joint Capsule
- The capsule of the hip joint encloses the joint and has attachments to the acetabular labrum medially.
- The capsule attaches laterally to the intertrochanteric line of the femur in front and along the posterior aspect of the femur's neck behind.
Hip Joint Ligaments
-
Iliofemoral ligament: A strong, inverted Y-shaped ligament.
-
The base attaches to the anterior inferior iliac spine.
-
The two limbs attach to the upper and lower parts of the intertrochanteric line of the femur.
- This ligament prevents overextension during standing.
-
-
Pubofemoral ligament: A triangular ligament attached to the superior ramus of the pubis.
- The apex is attached below to the lower part of the intertrochanteric line.
- This ligament limits extension and abduction.
- The apex is attached below to the lower part of the intertrochanteric line.
-
Ischiofemoral ligament: A spiral-shaped ligament attached to the body of the ischium near the acetabular margin.
- Fibers extend upward and laterally, attaching to the greater trochanter.
Hip Joint Relations
- Anterior Relations: Iliopsoas, pectineus, and rectus femoris muscles
- Posterior Relations: Obturator internus, gemellus, and quadratus femoris muscles (and sciatic nerve)
- Superior Relations: Piriformis and gluteus minimus muscles
- Inferior Relations: Obturator externus tendon
Hip Joint Nerve Supply
- Femoral nerve
- Obturator nerve
- Sciatic nerve
- Nerve to the quadratus femoris
Hip Joint Movements
-
The hip joint has a wide range of movement, but less than the shoulder joint.
-
The bones' shape and strong ligaments contribute to the joint's strength and stability.
-
Movements include flexion, extension, abduction, adduction, lateral rotation, medial rotation, and circumduction.
-
Extensor muscles are generally more powerful than flexor muscles.
-
Lateral rotators are typically stronger than medial rotators.
Additional Notes
- Ligament of the Head of the Femur: A flat, triangular ligament attached to the fovea capitis on the femoral head. Its base attaches to the transverse ligament and the margins of the acetabular notch.
- Synovial Membrane: Lines the synovial membrane, attaches to articular margins, covers parts of the femoral neck within the joint capsule, encloses the ligament of the head of the femur, and covers a fat pad in the acetabular fossa.
