Congenital Hip Dislocation:

  • More prevalent in the hip than in any other joint
  • Arises from a developmental deficiency in the upper margin of the acetabulum, causing the femur head to move upward onto the gluteal surface of the ilium

Traumatic Dislocations:

  • Three types: posterior (more frequent), anterior, or central
  • Posterior hip dislocation can lead to sciatic nerve injury

Fractures:

  • Fractures of the femoral neck are common in older individuals due to minor injuries. Damage to retinacular arteries results in avascular necrosis of the femoral head.
  • Trochanteric fractures commonly occur in robust, adult individuals and are typically the outcome of severe and violent injuries.

FAQs on Hip Joint - Medical Science Optional Notes for UPSC

1. What are the articular surfaces of the hip joint?
Ans. The articular surfaces of the hip joint are the acetabulum of the pelvis and the head of the femur. The acetabulum is a concave socket located on the lateral side of the pelvis, while the head of the femur is a spherical ball-like structure that fits into the acetabulum.
2. What ligaments support the hip joint?
Ans. The hip joint is supported by several ligaments. The ligaments of the hip joint include the iliofemoral ligament, pubofemoral ligament, and ischiofemoral ligament. These ligaments help to stabilize the hip joint and prevent excessive movement.
3. What is the neurovascular supply of the hip joint?
Ans. The neurovascular supply of the hip joint is primarily provided by the branches of the medial and lateral circumflex femoral arteries. These arteries supply blood to the hip joint, while the nerves such as the femoral nerve and obturator nerve provide the innervation.
4. What are the relationships of the hip joint?
Ans. The hip joint is located in close proximity to various structures. Anteriorly, it is related to the inguinal ligament and the femoral nerve. Posteriorly, it is related to the gluteus maximus muscle and the sciatic nerve. Laterally, it is related to the tensor fasciae latae muscle and the iliotibial tract. Medially, it is related to the adductor muscles and the obturator nerve.
5. What are some common hip joint disorders?
Ans. Some common hip joint disorders include osteoarthritis, rheumatoid arthritis, hip bursitis, hip labral tears, and hip impingement. These conditions can cause pain, stiffness, and limited range of motion in the hip joint. Treatment options vary depending on the specific disorder but may include medication, physical therapy, and in severe cases, surgical intervention.
