Artroplastia total de cadera en anquilosis y artrodesis

Fifty-six cases of total hip arthroplasty in ankylotic or arthrodetic hips were studied. The clinical and radiographic results justified the use of this therapeutic measure in cases of pain in the low back, homolateral knee, or contralateral hip secondary to these processes, as well as in cases of fusion in a defective position or painful pseudoarthrosis. The technique was not complication-free: hip fracture (3.6%), prosthetic dislocation (3.6%) and severe periprosthetic ossification (9%). Detailed study of the abductor muscles is important, as well as a suitable rehabilitation before and after surgery to strengthen the muscles and to counteract preoperative Tendelemburg deformity.
