Hip dislocation or subluxation is an unstable condition of the hip joint that gives a feeling of 'giving way' or that the hip has suddenly lost its stability.
Hip dislocation or subluxation is more often caused by trauma like direct hit to the hip joint but it may also occur due to gradual weakening of the ligaments and cartilage that supports the hip. It results in the forceful removal of the ball of the joint from its socket.
Dislocation or subluxation of hip is characterized by swelling, numbness, weakness and bruising of the joint area. It may also cause pain and weakness that interfere with activities like walking, running, getting up from a chair, or swinging leg around.
