After congenital dislocation of the hip, Perthes' disease and some other conditions, the femoral neck may be short and the greater trochanter in a relatively proximal position. Distal transfer of the greater trochanter is an effective and relatively simple operation to correct this deformity. We have reviewed 26 patients (27 hips) at a mean follow-up of eight years. Pain relief and improvement in gait were maintained in 74%, and the poor results were largely due to progression of
We studied the stability of cemented all-polyethylene keeled glenoid components by radiostereometric analysis (RSA) in 16 shoulders which had received a total shoulder replacement. There were 14 women (one bilateral) and one man with a mean age of 64 years. The diagnosis was
Forty-two shoulders in 37 patients with polyarthritis were treated with Neer total shoulder replacements and reviewed 12 to 66 months afterwards. There was good pain relief and improvement in function, but the range of movement was less than that seen after replacements for
Revision of a total knee arthroplasty may require an extensile approach to permit a satisfactory exposure without compromising the attachment of the patellar tendon. It has been assumed that a rectus snip is a relatively benign form of release, but the effect of using this approach on function, pain and patient satisfaction is not known. From January 1997 to December 1999, 107 patients who underwent revision of total knee arthroplasty were followed up at a minimum of two years (mean 40.5 months) and assessed by the Oxford Hip Score, the Western Ontario and McMaster Universities
1. Sixty-one cases of compression of the ulnar nerve are reported, forty at the elbow and twenty-one at the wrist. Although contributory factors may include deformity,
We investigated the effect of vitamin D receptor gene (VDRG) polymorphism on the responsiveness to 1,25(OH). 2. D. 3. in human osteoblast-like cells. The cells were obtained from the femoral heads of 18 women with
Substance P is readily detected in the synovial fluid of the knee in which it acts as a powerful inflammatory agent in response to injury and disease. It may be an objective predictor of pain after knee replacement surgery. The level of substance P was measured in the synovial fluid in both knees of 114 patients having unilateral and in 86 patients having bilateral total knee replacement for
We analysed the histological findings in 1146 osteoarthritic femoral heads which would have been considered suitable for bone-bank donation to determine whether pathological lesions, other than
In an experimental clinical study, 25 implants of pure titanium were inserted into the proximal tibia of 11 volunteer patients, four with rheumatoid arthritis and seven with
We report two cases in which arthrodesed knees were revised to total arthroplasties after the use of soft-tissue expanders. Case 1 had had multiple operations on her knee and had been arthrodesed for septic arthritis two years earlier. Case 2 had had knee arthrodesis for severe
Surgical exposure of the ankle is usually obtained by an anterior approach, especially for replacement arthroplasty. The transfibular approach has been popular for arthrodesis. We describe a new posterior approach to the ankle and posterior subtalar joint based on an extra-articular vertical calcaneal osteotomy behind the subtalar joint. The posterior flap so formed is hinged medially and offers wide exposure of the back of the ankle and posterior subtalar joint. This hinge allows safe and stable reduction of the osteotomised calcaneum, and the plane of dissection follows an ‘internervous plane’ behind the fibula. We have had good results after using this incision in 12 patients with
We present the long-term results of the Kinematic Condylar Knee Arthroplasty followed in a prospective fashion. Between October 1982 and March 1988, 404 consecutive replacement arthroplasties were carried out on 335 patients. Of these, 354 knees had
A reduced retroversion angle of the humeral head may predispose to recurrent anterior shoulder dislocation and may also be a factor in persistent instability after soft-tissue repair. We performed rotational osteotomy of the proximal humerus in 20 patients with recurrent anterior shoulder dislocations (10 traumatic, 10 non-traumatic) and a decreased retroversion angle of the humeral head. The mean preoperative retroversion angle was 12 degrees, which was increased after surgery to a mean value of 32 degrees. All patients regained a normal range of shoulder motion and normal function within three months after surgery. At the five-year review all shoulders were stable, pain-free and had no radiological signs of
Fifty-seven Stanmore Total Hip replacements were implanted between 1974 and 1986 in patients under the age of 50 years. We have reviewed the results in terms of survivorship and function, and assessed the reasons for revision. Of the original 57, 22 (39%) have been revised at an average of 12 years from implantation, usually for aseptic loosening. Most of them had originally been implanted for
We describe a prospective study of 328 patients undergoing arthroscopy of the hip. Arthrography, CT or MRI was performed when clinically indicated. A preoperative diagnosis was reached in 174 patients (53%), while the remaining 154 were diagnosed as having ‘idiopathic hip pain’. In seven patients, access to the hip was inadequate. Arthroscopy altered the diagnosis in 176 hips (53%). The new primary diagnoses were
We enrolled 98 patients (107 hips) with a mean age of 47 years (SD 8.6) into a prospective study of the Madreporic Lord THR; 34 hips had primary and 73 secondary
We studied the morphology of the haversian canals in the osteopenic cortical bone of the medial femoral neck from patients with rheumatoid arthritis and compared the findings with those in patients with
