1) Our attention has been called to an omission in the account sent to us of the May 1957 meeting of the South-West Orthopaedic Club held at Bath (Journal of Bone and Joint Surgery, 39-B, 789). In the description of the treatment of cavo-varus foot and club foot by Mr Dillwyn Evans, the words tendo calcaneus should be followed by the words "and perform calcaneo-cuboid arthrodesis.". 2) Novemter 1957, 39-B, 793, last line: for plaster, read water

1. Patients subjected to the flexor-extensor transplant have been reviewed. The results in forty feet were assessed by direct questioning and examination, and the results of a further five operations were assessed from the records. 2. Worthwhile improvement was gained in a little over half the cases. The chances of success are greatest when the symptoms are mildest. 3. The operation appears to be inadequate in certain respects and it seems doubtful whether it has any advantage over the multiple arthrodesis (Lambrinudi) operation

1. A complete replacement arthroplasty of the hip is described in which both components are inherently stable. 2. The arthroplasty does not require the use of acrylic cement. 3. It is appropriate for the treatment of the severely arthritic hip in which arthrodesis is not indicated, and for the mobilisation of two stiff and painful hips at any age. 4. It can be performed on both sides at the same time. 5. It produces a stable, pain-free and mobile joint in a high proportion of cases, and has appeared not to deteriorate over periods of up to four years

We describe the surgical technique and results of arthroscopic subtalar release in 17 patients (17 feet) with painful subtalar stiffness following an intra-articular calcaneal fracture of Sanders’ type II or III. The mean duration from injury to arthroscopic release was 11.3 months (6.4 to 36) and the mean follow-up after release was 16.8 months (12 to 25). The patient was positioned laterally and three arthroscopic portals were placed anterolaterally, centrally and posterolaterally. The sinus tarsi and lateral gutter were debrided of fibrous tissue and the posterior talocalcaneal facet was released. In all, six patients were very satisfied, eight were satisfied and three were dissatisfied with their results. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score improved from a mean of 49.4 points (35 to 66) pre-operatively to a mean of 79.6 points (51 to 95). All patients reported improvement in movement of the subtalar joint. No complications occurred following operation, but two patients subsequently required subtalar arthrodesis for continuing pain. In the majority of patients a functional improvement in hindfoot function was obtained following arthroscopic release of the subtalar joint for stiffness and pain secondary to Sanders type II and III fractures of the calcaneum

We describe a congenital deformity of the foot which is characterised by calcaneus at the ankle and valgus at the subtalar joint; spontaneous improvement does not occur and serial casting results in incomplete or impermanent correction of the deformities. Experience with five feet in four children indicates that release of the ligaments and tendons anterior and lateral to the ankle and lateral to the subtalar joint is the minimum surgery necessary; subtalar arthrodesis may be required in addition. The foot deformity described may occur as an isolated condition or in association with multiple congenital anomalies. The possibility of a neurological deficit should always be excluded

The St Georg modular knee replacement has been studied in 59 cases with an observation period ranging from 28 to 73 months. In 47% of the knees both compartments were replaced; five of the six poor results were in this group. These were revised to a hinge arthroplasty or, in one case, to an arthrodesis. Other complications were few and insignificant. There were no infections. We concluded that unicompartmental knee arthroplasty can be recommended when joint involvement is localised to one compartment only. With more generalised joint disease we prefer a semiconstrained total condylar prosthesis

Thirty-seven patients have been reviewed after arthrodesis of the ankle in order to determine the reduction of dorsiflexion and plantarflexion of the foot, the incidence of tarsal hypermobility and its relevance to the clinical results of this procedure. Radiological methods of measuring movements in the foot and tarsus are described and applied to patients who had a normal foot on the opposite side which could be used as a control. Our findings suggest that tarsal hypermobility is not as common as has hitherto been supposed and that a stiff foot with minor radiological degenerative changes in the tarsal joints is quite compatible with an excellent result

Our investigations have shown that the late results of tarsal arthrodesis are good. We have endeavoured to find the disadvantages and to stress residual symptoms, but the general mpression after seeing these patients is that they were all well satisfied with the result. We think it should be added that these patients were selected in so far as they were all operated upon by masters of operative technique who were acknowledged authorities in this particular subject. Without the careful attention to detail and to the points discussed, these operations can be dismal failures and a burden to the patients concerned

Between June 1991 and May 1996 we carried out arthrodesis on 15 patients with flail or partially flail wrists using an AO/ASIF dynamic compression plate (DCP) without a bone graft. The wrist was approached through the second extensor compartment. The minimum follow-up was for 24 months with a mean of 34.2 months. All 15 wrists fused without major complications at a mean of 11.9 weeks. Stabilisation improved the function of the hand affected with paralysis and the appearance of the extensively paralysed upper limb with a flail hand. In the absence of bony abnormality fusion can be obtained with a DCP alone without the need for bone grafting

We have reviewed 15 patients with infected total knee replacements after removal of the prosthesis, rigorous debridement, antibiotic irrigation, and prolonged systemic antibiotics. Infection was permanently eradicated in all patients; they were left with a functioning limb, on which they could walk with either a caliper (8 patients), a simple splint (3), crutches, or sticks. Three were disappointed because of residual pain. We believe that, if exchange arthroplasty is inappropriate, this procedure is preferable to arthrodesis or amputation for persistent and disabling infection, particularly where constrained artificial joints have been used

1. A study has been made of thirty-two patients who had had operations for their spastic hands. 2. In twenty-seven a flexor muscle slide was done, either by itself or in association with an arthrodesis of the wrist. The rationale of the operation is discussed. 3. The first muscle slide was done in 1959 and the average follow-up was seven and a half years. 4. Selection is crucial : drive, usually coupled with intelligence, is essential for success. 5. Operation is not a replacement for physical therapy. The object is to make rehabilitation easier. The flexor muscle slide, in carefully chosen cases, may play a significant part in achieving this

We describe the results of total knee arthroplasty (TKA) undertaken for severe, neurosyphilitic Charcot arthropathy in ten patients (19 knees). A cemented condylar, constrained prosthesis was implanted in all but two knees. The mean follow-up was 5.2 years (5 to 6). The mean knee score before operation was 36.5 points (30 to 42) which improved to 76 points (58 to 90) after operation as judged by the Hospital for Special Surgery score. At final follow-up three knees (16%) had aseptic loosening which required salvage by an arthrodesis, six (31%) were functioning poorly and ten (53%) were satisfactory. We conclude that although Charcot arthropathy is not an absolute contraindication to total knee replacement, there is a high incidence of serious complications

Aims

Total ankle arthroplasty (TAA) has become the most reliable surgical solution for patients with end-stage arthritis of the ankle. Aseptic loosening of the talar component is the most common complication. A custom-made artificial talus can be used as the talar component in a combined TAA for patients with poor bone stock of the talus. The purpose of this study was to investigate the functional and clinical outcomes of combined TAA.

Aims

The modified Dunn procedure has the potential to restore the anatomy in hips with severe slipped capital femoral epiphyses (SCFE). However, there is a risk of developing avascular necrosis of the femoral head (AVN). In this paper, we report on clinical outcome, radiological outcome, AVN rate and complications, and the cumulative survivorship at long-term follow-up in patients undergoing the modified Dunn procedure for severe SCFE.

We reviewed 19 children with 24 congenital club feet at a mean of 11 years after one-stage posteromedial release at the age of five years or older (mean 6.8 years). Thirteen feet had undergone previous surgery. Nineteen feet were functionally excellent or good, three were fair and two had required subtalar arthrodesis. Radiographs showed good alignment of the tarsal bones, although mild adduction or varus deformity remained in several feet. Deformities of the bones were more common in feet which had had previous surgery

We performed 52 cemented ankle arthroplasties for painful osteoarthritis (OA) (25) or rheumatoid arthritis (RA) (27) using an ankle prosthesis with a near-anatomical design. We assessed the patients radiologically and clinically for up to 14 years using an ankle scoring system. The preoperative median scores were 29 for the OA group and 25 for the RA group and at ten years were 93.5 and 83, respectively. Six ankles in the OA group and five in the RA group required revision or arthrodesis. Survivorship analysis of the two groups showed no significant differences with 72.7% survival for the OA group and 75.5% for the RA group at 14 years

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 osteoarthritis 18 years before revision. In both patients, tissue expanders were used to increase the soft tissues available for cover and to help to mobilise the extensor mechanism. The operations were made much easier, and in both patients a range of motion from 0 degrees to 90 degrees was achieved at operation

The results of 62 ankle arthrodeses, mostly performed for osteoarthritis, have been reviewed; of these, 39 were examined clinically and radiographically after an average follow-up period of seven years. Compression arthrodesis was associated with the highest incidence of complications, and an anterior sliding graft gave the most satisfactory results. Very few patients required modification of their footwear; most could walk independently with a slight limp and were able to return to their pre-operative work. However, after operation, the ability to run and to participate in vigorous sporting activities was limited. Complications included wound infection, non-union, and some change in midtarsal mobility, but excellent pain relief was reported by all patients

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 osteoarthritis or rheumatoid arthritis and there have been no difficulties with wound healing

1. A study is presented of 286 extra-articular subtalar arthrodeses done during the years 1958 to 1965 on 258 patients with pes calcaneo-valgus, pes planovalgus, pes varus or flail foot. 2. Certain changes in the surgical technique originally presented by Grice have been made. We have applied the arthrodesis not only to valgus feet but also to varus feet, and we have described the details of the surgical technique as used on the varus foot. 3. In none of our cases was there failure of fusion or reabsorption of the graft. The unsatisfactory results (239 per cent) were caused by residual varus or valgus deformity of the foot
