Hip Dislocation: Traumatic Causes, Distinctive Symptoms, and Reduction Procedures.
Hip dislocation, unlike congenital hip dysplasia, occurs when an intense force is applied to the knees in a posterior direction while the hips and knees are flexed. This pushes the femoral head backward, forcing it out of the acetabulum. Impacts, falls, or trauma typically cause this event.
The severity of this injury lies not only in the displacement itself but in the fact that it is often accompanied by other significant injuries.
It is associated with femoral head, patella, or acetabular fractures, ACL injuries, and severe complications like sciatic nerve injury or late osteonecrosis if the femoral head is not relocated promptly.
Symptoms:
Pain is intense, and the patient remains immobilized. In posterior dislocation, the leg appears shorter and rotated inward. In anterior dislocation (less frequent), the leg rotates outward, and shortening is less obvious.
Management:
The treating physician will perform a Reduction to return the hip to its socket, usually under sedation or anesthesia. Afterward, new X-rays or a CT scan must be performed to detect bone fragments or hidden fractures.
If no other acute injuries are found, the patient is likely sent home with crutches for a week and scheduled for follow-ups with a hip specialist to monitor the health of the joint cartilage and femoral head.
