HIP ANKYLOSIS AS SEQUELAE OF CHILDHOOD HIP PATHOLOGY TREATED WITH TOTAL HIP ARTHROPLASTY: REPORT OF TWO CASES

Abstract

Total hip arthroplasty (THA) is an emerging surgery in the field of orthopedics with a successful outcome in treating various problems of the hip joint. THA in hip ankylosis is a challenging procedure. Comprehensive pre-operative planning is needed to avoid complications and obtain reasonable functional outcomes. Complete history taking is needed to determine the etiology, indications, type of ankylosis (spontaneous or surgical), age since ankylosis occurred, and previous complications. Physical examination is also important and is focused on the location of the previous incision, limb length discrepancy (LLD), femoral and sciatic nerves, vascular status, pelvic obliquity, spine problems, and range of motion of the ipsilateral knee, and also of contralateral hip and knee. In addition, surgery rehabilitation also becomes one of the important points to get a good clinical outcome. We reported the results of total hip arthroplasty to treat hip ankylosis as sequelae of childhood hip pathology.
