Proximal migration of the ununited greater trochanter following total hip arthroplasty may produce pain and substantial functional disability. Successful reattachment of the migrated fragment is difficult following multiple hip procedures. The purpose of this report is to describe four patients in whom a severely migrated trochanteric fragment was reattached successfully with a modified Charnley-Harris wiring technique after subperiosteal advancement of the abductor muscles from their origin on the iliac wing.


This series consisted of one man and three women with an average age of sixty years (range, fifty-one to sixty-eight years) at the time of the index procedure. The patients were followed for an average of eighty-one months (range, fifty-five to ninety-six months). All patients had undergone mobilization of the abductor muscles based on the superior gluteal neurovascular pedicle to aid with trochanteric reattachment, and all had undergone prior hip operations (average, two). Advancement of the abductor muscles was achieved through a separate transverse curvilinear incision over the iliac crest, and subperiosteal releases of the entire origins of the gluteus minimus, medius, and maximus muscles from the ilium were performed.


Roentgenographic union of the trochanteric fragment occurred in all four patients. There were three excellent functional outcomes (Harris hip scores of 90, 94, and 96 points) and one fair functional outcome (76 points). The average improvement in the Harris hip score was 47.5 points (range, 35 to 58 points). Two patients continued to have a mild or moderate Trendelenburg gait postoperatively. Two patients had heterotopic bone formation of no clinical importance.


Use of this technique resulted in union of the greater trochanter, pain relief, and decreased functional disability without major complications in these four patients. More widespread use of this technique may be indicated for the treatment of symptomatic non-union of the greater trochanter when the fragment cannot be reattached to its anatomical location with the hip in less than approximately 20 degrees of abduction.
