A retrospective study of the long-term follow-up of patients with Austin Moore prostheses is presented. Sufficient data were present to evaluate 78 hips postoperatively at six months, and 1, 5, 10, and 15 years when applicable. The average age of patients at the time of operation was 56.1 years. Most preoperative diagnoses resulted from previous operative procedures which had failed (there were only six fresh fractures). The operative technic is discussed. Postoperatively, cessation of pain is relatively early and the return of function increases linearly but at a slower rate. The importance of partial weight-bearing for four to six months postoperatively as well as daily physical therapy is emphasized. The mean amount of settling of the prostheses (total in the femur and acetabulum) was 1.63 cm in all patients. We believe that certain postoperative principles are applicable to all types of reconstructive surgery of the hip.

In a follow-up study of 239 consecutive patients with fractures of the femoral neck treated by six surgeons in one hospital by Pugh nailing, Austin Moore prosthesis, or Knowles pinning, 96 per cent could be followed for a minimum of two years or until a definitve result had been reached. The incidence of unsatisfactory results was 39.3 per cent after Pugh nailing, 18.2 per cent after prosthetic replacement, and 14.2 per cent after Knowles pinning (mostly undisplaced or impacted fractures). Thirty-five unsatisfactory results following Pugh nailing were due to: aseptic necrosis which was definite in eighteen cases and probable in two; early mechanical failure in twelve cases; infection in one; and late non-union in two. Eight poor results followed prosthetic replacement and were due to erosion of the acetabulum in six and dislocation in two. The four poor results that followed Knowles pinning were due to aseptic necrosis in three and to pain, probably the results of aseptic necrosis, in another. From this study it was concluded that aseptic necrosis was more influenced by the original displacement than by the accuracy of reduction or fixation, and that in displaced femoral-neck fractures in the elderly, prosthetic replacement gave a more reliable result.

Clinical trials were conducted at the Foot Clinics of New York, testing the use of the Johnson & Johnson Orthosorb absorbable pins as an integral absorbable form of fixation of the Austin osteotomy. Two Orthosorb pins were inserted across the osteotomy from dorsal to plantar. Patients were placed in a plaster splint and allowed to walk with weightbearing as tolerated within 2 weeks of the procedure. A protocol was designed to include a 6-month follow-up with regularly scheduled postoperative examinations. These examinations included a review of pain, walking ability, edema, and measurements of dorsiflexion and plantarflexion. No complications have occurred in this patient population. This study has shown that for a selected group of surgical candidates, Orthosorb bioresorbable pins are an effective form of fixation for the Austin osteotomy.

We performed a randomised prospective trial to compare the results of 27 cemented and 26 uncemented bipolar hemiarthroplasties in active patients with displaced subcapital fractures of the femoral neck. After a mean follow-up of 17 months, significantly more of the uncemented group were experiencing pain in the hip and using more walking aids than the patients in the cemented group. The incidence of postoperative complications, the early mortality rate and the operating time and blood loss were not significantly different. Using otherwise identical prostheses the early results were much better with a cemented Thompson stem than with an uncemented Austin Moore stem.

278 geriatric patients with fractured proximal end of the femur were studied retrospectively 1.5-5 years (average 3.5 years) after they received treatment in two hospitals. Of the survivors 63%, 56% were totally pain-free while 15% had varying degrees of hip pain. Only 26.5% could squat fully. The physical activity was inversely proportional to the age. The widowed were doing better than the married with living husbands. Of the three methods of treatment (Austin-Moore hemiarthroplasty, plating and Ender's nailing), the hemiarthroplasty group of patients was doing the best physically. In spite of some positive X-ray findings among the different groups, corresponding clinical manifestations were not encountered.

A consecutive series of 71 Bateman hemiarthroplasties were performed in a single hospital over a 20-month period. Forty-four hips or 62% were available for review with an average follow up of 22 months. Of the 44 cases, the Bateman Universal Proximal Femur, original design was used in 40 acute, displaced femoral neck fractures, two failed Austin Moore prostheses, and two cases of femoral head osteonecrosis unassociated with fracture. The mean Harris hip score was 84.7%. Of the patients 93.2% had minimal or no pain. The range of motion was excellent and the dislocation rate was 1.8%. Morbidity was not increased compared to more conventional unipolar implant procedures. The Bateman Universal Proximal Femur (UPF) is felt to offer improved surgical results compared to Austin Moore and Thompson prostheses, and this may be due to the low friction inner bearing motion that occurs with this bipolar implant.

In this study the results of the use of Austin Moore's and Monk's protheses in displaced subcapital femoral neck fractures have been compared. Patients treated with Monk's prosthesis did better. The relief of pain and sense of security in the early postoperative days were noteworthy findings in patients with Monk's prosthesis. No cases of fat embolism or cardiac arrest were reported with the use of cemented Monk's prosthesis.

Thirty-two elderly patients with a femoral neck fracture treated by bipolar hemiarthroplasty and 36 patients (matched for age) with an Austin-Moore hemiarthroplasty were followed-up and compared. Bipolar replacement resulted in a higher percentage of satisfactory results, less postoperative pain, greater range of movement, more rapid return to unassisted activity, fewer unsatisfactory results and no acetabular erosion. The device functioned as bipolar in all the cases studied for inner-bearing motion.

This study reports the results of revision total hip arthroplasty with the Anatomic Porous Replacement Revision Hip System (Intermedics Orthopedics, Austin, TX) to investigate the value of cementless fixation. Sixty-six hips in 65 patients were followed for a mean of 4.7 years in patients with a mean age of 56 years. Thirty-six patients were categorized as Charnley class A, 16 as class B, and 13 as class C. Forty (61%) of the femurs were classified before surgery as having loss of bone distal to the intertrochanteric line. Thirty-two (48%) of the femurs required augmentation with demineralized strut cortical allografts, 5 (8%) required bulk femoral allografts, and 12 hips (18%) required acetabular allografts. Overall, 4 stems (6%) and 2 acetabular components (4%) required further revision surgery. The reason for further revision in 1 stem and both acetabular components was allograft failure. Fifty-six (85%) hips had excellent or good Harris hip scores. Ninety percent of hips had no or slight pain, and 90% allowed patients to walk with no or slight limp. Those hips that had hydroxyapatite coating added to the porous coating had statistically improved Harris hip scores for both pain and limp. Stable fixation was present in 95% of stems. Demineralized strut grafts healed in 30 of 32 hips. Thirty-nine of 44 noncemented revision sockets had no radiolucent lines and there were no loose components. Cementless fixation was effective for these hips.

Forty cases of Austin Moore Replacement done for transcervical fractures of the femur in patients were reviewed after a period of 12 to 48 months postoperatively (mean 26 mth). 30 cases (75%) had mild to severe pain of non-infective origin, starting as early as 6 months postoperatively. This was irrespective of the make, size or position (varus/valgus) of the prosthesis. Though the Aufranc and Sweet clinical scoring was satisfactory in 65% cases, radiological evidence of complications like sinking, protrusion, etc. were seen in majority of the cases. Calcar resorption was seen in 34 cases (85%) as early as 4 months postoperatively. Results of THR and bipolar replacement done for transcervical fractures in recent literature show 85% pain-free cases at 5 years. We feel that Austin Moore Replacement should be reserved for patients more than 65 years of age and those who are less active or debilitated because of other factors, because of increased acetabular wear with time in the younger individual. This is corroborated by unsatisfactory results in patients less than 65 years of age (p < 0.05).
