Colonna Greater Trochanteric Arthroplasty for Septic Hip Sequelae: Long-term Follow-up of Two Cases / 대한정형외과학회잡지

ABSTRACT

Hip dislocation and associated instability in septic hip arthritis, caused by destruction of the femoral head and neck and damage of the proximal femoral epiphysis, is difficult to treat. Colonna greater trochanteric arthroplasty, which places the greater trochanter into the acetabulum, can provide stability and increased function in the hip joint. The greater trochanter can be remodelled to act as a femoral head. We report 2 cases of Colonna greater trochanteric arthroplasty, which were observed twelve and twenty years after surgery. Although the patient had limited motion of the hip joint, which was accompanied by pain and limping, the overall results were satisfactory. In summary, we believe that Colonna greater trochanteric arthroplasty is an effective way of achieving a stable hip joint in a difficult septic hip sequelae. Limb length discrepancy can be corrected by a limb lengthening procedure at a later stage. In addition, conversion to a total hip arthroplasty is much easier than in unreduced high dislocation.
