The best treatment for a fractured neck of femur in an old person is considered by many to be replacement hemiarthroplasty which allows the patient to walk immediately on a stable, painless hip. The late results can be marred by acetabular erosion in which the metal head of the prosthesis erodes upwards into the acetabulum to give pain and disability. Here the trial of a new bipolar prosthesis with a dynamic self-aligning outer head is described in 161 fractured necks of femur. No acetabular erosion has been seen with its use over four years.

The case histories of 361 subcapital fractures of the femoral neck in 354 patients treated by primary replacement with the cemented Thompson prosthesis were reviewed, and 156 survivors were seen at follow-up. The average age was eighty-one years. Three hundred and thirty fractures occurred in women and thirty-one in men. The antero-lateral approach to the hip was used at all operations because it allows immediate and unrestricted mobilisation after operation. It is considered that this method is the best treatment in the rehabilitation of elderly patients after high femoral neck fractures, because of its low morbidity and high success rate in returning the geriatric orthopaedic patient to independence. The results after an average of just over three years were available for 161 hips in 156 patients studied at follow-up. Of these, 132 (82 per cent) were satisfactory. Most of the unsatisfactory results were in patients under seventy-five years of age. Out of the whole group of 361 hips treated the important early complications were wound infections in seventeen hips 4-7 per cent), all of which resolved, and dislocation in seven hips (2 per cent). Forty-six patients (12-9 per cent) died during the first four weeks after operation, their average age being eighty-five. One hundred and seventy-one patients (47-4 per cent) were discharged from hospital within under four weeks of the operation. Acetabular erosion and loosening are shown to be the important later complications. Three patients had late sepsis.

Link arthroplasty is a system of joint replacement in which the joint is left almost intact with no great removal of bone. It is based on a two-piece self-locking hinge slotted into the metacarpal head and phalangeal shaft. The operation is simple and no special instruments are needed. The preliminary follow-up of fifty-four metacarpo-phalangeal joint replacements showed thirty-five good and sixteen fair results.
