GROSS ANATOMY

Detailed explanation-1: -Anterior hip dislocation is commonly reduced by inline traction and external rotation, with an assistant pushing on the femoral head or pulling the femur laterally to assist reduction. Posterior hip dislocations are the most common type and are reduced by placing longitudinal traction with internal rotation on the hip.

Detailed explanation-2: -The rate of dislocation of primary hip replacements ranges from 0.2% to 10% per year, while that of artificial hip joints that have already been surgically revised can be as high as 28%, depending on the patient population, the follow-up interval, and the type of prosthesis.

Detailed explanation-3: -Nonsurgical reduction by manipulation: Usually, an orthopedist can simply push the ball back in by hand while the patient is under anesthesia. If, however, the imaging reveals fractures or significant damage to soft tissues, blood vessels or nerves, orthopedic surgery may be required.

Detailed explanation-4: -There are three types of anterior hip dislocations: obturator, an inferior dislocation due to simultaneous abduction; hip flexion; and external rotation. Iliac and pubic dislocations are superior dislocations due to simultaneous abduction, hip extension, and external rotation.
