We reported the results of nine ipsilateral femoral fractures after total hip arthroplasty (THA) and bipolar hemiarthroplasty (BHA) which were combined with a loose femoral component. Nine patients, three men and six women, were operated on with Huckstep prosthesis between November 1990 and November 1999. According to Johansson's classification, there were six type I fractures, three type II fractures and no type III fracture. All cases underwent the revision THAs which were cementless, long femoral components (Huckstep prosthesis). We attemped to restore femoral bone volume and bone quality with allograft and articial bones (hydroxyapatite and AW glass ceramic).
All fractures were fused without complications and all femoral components had good fixation without loosening and sinking. Finally, the hip scores of the Japanese Orthopaedic Association were from 68 to 98 points (average, 77 points).
Revision THAs with Huckstep prosthesis were possible to maintain the reposition, correct the leg length and restore the bone stock with bone graft.
