Study Notes
ANTEROMEDIAL THIGH & HIP JOINT
-
Cribriform fascia: a deep layer of superficial fascia, it is located over the fossa ovalis and iliac crest
-
Cutaneous Nerve:
- Patellar plexus: located in front of the knee. Includes terminal branches of the lateral, intermediate, and medial cutaneous nerves of the thigh, a terminal branch of the lumbar plexus and femoral nerve, and the infrapatellar branch of the saphenous nerve.
- Saphenous Nerve: another branch of the femoral nerve that descends down, innervating the patellar area.
-
Superficial Lymph nodes:
- Divided into horizontal and vertical groups
- Located along the inguinal ligament and are responsible for draining the lower extremities
-
Deep Fascia:
- Covers the muscles
OBTURATOR NERVE & VESSELS
-
Obturator Nerve Arises from the lumbar plexus (anterior division of L2, L3, L4 spinal nerves) and emerges at the medial border of the psoas muscle within the abdomen.
- Leaves the pelvis through the obturator foramen and divides into anterior and posterior divisions
- Anterior Division: Innervates adductor longus, brevis, and gracilis.
- Posterior Division: Supplies adductor magnus.
- Leaves the pelvis through the obturator foramen and divides into anterior and posterior divisions
HIP JOINT
- Type: Synovial, Ball & Socket joint
- Diarthrosis: Freely movable joint
- Articulating bones: Head of femur & acetabulum
-
Capsule: Attached to the:
- Acetabular labrum medially
- Intertrochanteric line & neck of femur laterally
- Protective & supportive parts: Joint capsule, synovial membrane, synovial fluid & cavity, ligaments
HIP JOINT LIGAMENTS
-
Intracapsular Ligaments: Found inside the joint capsule
- Ligament of head of femur: Only intracapsular ligament, a small structure that runs from the acetabulum to the fovea capitis of the femur.
-
Extracapsular Ligaments: Found outside the capsule
- Iliofemoral ligament/ Y-ligament of Bigelow: 2 strips of ligaments, coming from the ilium and connected to the base of the neck of femur. It prevents hyperextension of the hip joint.
- Pubofemoral ligament: Coming from the pubis and connected to the femur. It prevents abduction and extension.
- Ischiofemoral ligament: Coming from the ischium and connected to the base of the neck of femur. It prevents hyper extension.
HIP JOINT CAPSULE
- Protects the ball & socket joint
- Attached to the:
- Acetabular labrum above
- Base of neck of femur distally
