PHTY100 Lecture Notes - Lecture 5: Acetabular Labrum, Acetabular Notch, Hyaline Cartilage
Document Summary
Close packed position: maximum bone to bone contact, head of femur and acetabulum. Acetabular notch: inferior deficiency of acetabulum, transverse ligament fills. Acetabular labrum: fibrocartilage wedge, rim of acetabulum, deepens socket: head of femur: Fovea capitis: small area without cartilage on head. Attaches to labrum , surrounding bone and transverse ligament at notch. Reflected onto neck of femur attaching to intertrochantic line: synovial membrane: Superior band: limits extension, adduction, external rotation. Inferior band: limits extension, external rotation: pubofemoral: Breaches acetabular notch: acetabular fat pad: Articular fit, reasonable congruence: strong capsule, functions of muscles, acetabular labrum, angle of inclination: Iliopsoas: rectus femoris: knee extension, pectineus: hip adduction, tensor fascia lata: hip abduction, internal rotation, sartorius: hip abduction, external rotation. Muscles with line of pull parallel to neck of femur. Tibiofemoral: between tibial and femoral condyles, articular surfaces: Patellofemoral: between patellar surface of femur and articular surface of patella. Increases leverage that tendon can exert on femur.
