Background: A fracture of the greater trochanter through an
osteolytic lesion may occur as a late complication after total hip
arthroplasty. The optimal treatment for this difficult complication remains
controversial. We have treated this problem with internal fixation and
allogeneic bone-grafting at the time of revision of a loose acetabular
component.
Methods: We retrospectively reviewed the results of treatment of a
fracture through an osteolytic lesion of the greater trochanter in nineteen
patients seen from 1996 to 2002. All fractures were treated with morselized
allogeneic bone grafts and wire fixation at the time of revision of a failed
acetabular component. Postoperative care included the use of an abduction
orthosis and protected weight-bearing for at least three months. Follow-up of
all patients consisted of radiographic examinations and clinical evaluation
with use of the Harris hip score.
Results: At an average duration of 3.8 years after the revision,
eighteen of the nineteen fractures had healed. The average time to healing was
five months. The one treatment failure occurred in a patient who did not
comply with the use of an abduction orthosis. The average Harris hip score for
all patients improved from 32.5 points preoperatively to 91.2 points at the
time of the latest follow-up. Polyethylene wear and recurrent osteolysis of
the greater trochanter was noted in one hip at the eight-year follow-up
examination.
Conclusions: Fractures of the greater trochanter associated with
osteolytic lesions can be effectively treated with open reduction, internal
fixation with wire, and allogeneic bone-grafting.
Level of Evidence: Therapeutic Level IV. See Instructions
