Total joint replacement for ankylosed hips. Indications , technique, and preliminary results
HC Amstutz and DN Sakai
Sixteen patients with disabling pain in the back, knee, or hip had total
hip-replacement arthroplasty. Good relief of pain, a limited but
satisfactory range of motion (dependent on duration of ankylosis), and
variable function resulted. Establishing active abduction was important in
restoring function and achieving a negative Trendelenburg test. Careful
preoperative assessment of abductor muscle strength, medialization of the
acetabulum, use of long-neck prostheses with small and straight stems and
good inherent stability, and muscle reconditioning were the keys to a good
result.
