Hip joint arthrodesis utilizing anterior compression plate fixation

Sixteen patients who had undergone hip arthrodesis utilizing an anteriorly placed compression plate were evaluated at an average of 4.5 years after surgery. The technique was designed to facilitate future conversion to a total hip arthroplasty by preserving the abductor musculature. Of the 11 patients who underwent primary fusions, 5 failed to unite (45%). Nonunion occurred in all five (100%) patients undergoing refusion for a failed surgical arthrodesis. The authors conclude that an anterior compression plate alone in patients with limited bone stock does not provide adequate fixation and predisposes the patient to failure of fixation and nonunion.
