In this video, we break down the anatomy of the hip joint, how it moves, what supports it, and what happens when it gets damaged. We go layer by layer, starting with the bones and landmarks of the acetabulum and femur, then look at the joint capsule, synovial membrane, ligaments, and finish off by exploring three common conditions that affect the hip joint: osteoarthritis, gout, and rheumatoid arthritis. ________________________________________ Structures of the Hip Joint Bony structures involved • Head of femur (caput femoris): Articulates with the acetabulum to form the ball-and-socket joint. • Acetabulum (acetabulum): Concave socket in the pelvis that receives the head of the femur. Acetabular landmarks • Acetabular margin (margo acetabuli): The rim surrounding the acetabulum. • Acetabular notch (incisura acetabuli): A gap in the inferior rim of the acetabulum. • Lunate surface (facies lunata): Smooth, crescent-shaped surface that contacts the femoral head. • Acetabular fossa (fossa acetabuli): Central, non-articular depression in the acetabulum. Intra-articular structures • Acetabular labrum (labrum acetabulare): Fibrocartilaginous rim that deepens the socket and improves joint stability. • Transverse acetabular ligament (ligamentum transversum acetabuli): Bridges the acetabular notch to complete the socket rim. • Ligament of the head of femur (ligamentum capitis femoris): Connects the fovea of femoral head to the acetabular fossa and carries a small artery. • Acetabular fat pad (pulvinar acetabuli): Fat within the acetabular fossa that cushions and supports the ligament. Joint capsule • Synovial membrane (membrana synovialis): Inner layer of capsule producing synovial fluid. • Fibrous membrane (membrana fibrosa): Outer dense connective tissue layer providing mechanical stability. Capsular ligaments • Iliofemoral ligament (ligamentum iliofemorale): Y-shaped ligament from anterior inferior iliac spine to intertrochanteric line; resists hyperextension. • Pubofemoral ligament (ligamentum pubofemorale): Extends from pubic part of acetabulum to lower femoral neck; resists abduction and extension. • Ischiofemoral ligament (ligamentum ischiofemorale): Spirals from ischium to posterior femur; limits internal rotation. ________________________________________ Hip Joint Movements • Flexion (flexio): Thigh moves forward. • Extension (extensio): Thigh moves backward. • Abduction (abductio): Thigh moves laterally away from body. • Adduction (adductio): Thigh moves medially toward body. • Internal rotation (rotatio interna): Femur rotates inward. • External rotation (rotatio externa): Femur rotates outward. ________________________________________ Common Conditions Affecting the Hip Joint Osteoarthritis (OA) Pathophysiology • Degeneration of articular cartilage leads to joint space narrowing. • Bone-on-bone friction causes inflammation and osteophyte (bone spur) formation. • Risk factors: age, obesity, physical labor, joint trauma. • Symptoms: groin pain, stiffness less than 30 mins in the morning, reduced range of motion, crepitus. Gout Pathophysiology • Deposition of monosodium urate crystals in synovial membrane. • Causes acute inflammatory arthritis (synovitis). • Risk factors: CKD, obesity, purine-rich diet, alcohol, thiazide diuretics. • Symptoms: sudden pain, swelling, warmth, redness, extreme tenderness. Rheumatoid Arthritis (RA) Pathophysiology • Autoimmune disease targeting the synovial membrane. • Leads to pannus formation and joint destruction. • Risk factors: female sex, age 40–60, HLA-DR4, smoking. • Symptoms: symmetrical joint pain, stiffness longer than 30 mins, fatigue, deformity. ________________________________________ If you want a PDF version of this lecture, test your knowledge with a quiz, or explore a structured list of all anatomy videos, visit my website: taimtalksmed.com Sources: • Kozlowski, T.
