HIP
The hip joint is located in the pelvic girdle and consists of the acetabulum and proximal part of femur. This is a multiaxial ball-and-socket joint like the glenohumeral (shoulder) joint. The hip joint has a stronger labral rim combined with the ligament and capsule. Reinforcement by associated soft tissues provides good stability.

Total hip replacement
The hip joint is a multiaxial, ball and socket, weight bearing joint. People with severe arthritis in the hip joint, who experience severe pain, limited joint mobility and reduced functional ability, may need total hip replacement.

Causes
--Trauma
--Degeneration : Rheumatic Arthritis(RA), Osteoarthritis(OA), infectious hip joint, avascular necrosis and abnormal mechanical alignment of hip joint

Symptoms
--Pain : weight bearing on affected hip and walking and up and down stairs
--Reduced range of motion
--Fatigue : muscle weakness, muscle atrophy
--Functional changes : limp, difficulty standing from a seated position


The outside elastic force and anchor surrounding the waist stabilize the hip joint. The hip support can relieve heavy weight-bearing from the thigh and hip muscle.
