We describe the reconstruction of a defect of the medial malleolus which was the result of an accident in a ten-year-old child. A graft from the iliac crest, with the apophyseal cartilage and perichondrium, was used for reconstruction of the medial malleolus, the growth plate and the adjacent metaphyseal defect, respectively. The soft-tissue defect was covered with a free scapular flap with microvascular anastomosis. Three years after the injury stability of the ankle is excellent with adequate growth of the reconstructed epiphyseal plate

One hundred patients who had sustained a fracture of the tibial shaft and had been treated by internal fixation were reviewed to obtain information on residual ankle and subtalar disability. This study reinforces the belief that early mobilisation of patients with tibial shaft fractures does help to preserve subtalar movement

With the aim of controlling pain after Keller's operation, a solution of a long-acting local anaesthetic was instilled into the field before closure in a series of thirty patients. In a controlled prospective trial this simple technique by itself proved to be significantly better than either foot block at the ankle or the usual analgesics and was free from local or systemic complications

The interosseous route remains popular for tibialis posterior tendon transfer for drop-foot. It leaves a smaller range of movement than the circumtibial route, but lengthening the calcaneal tendon may improve this. The results of this present series indicate that, in order to predict a good functional result, the ankle must be held in at least 20 degrees of dorsiflexion at the time of tendon transfer

The clinical details of six patients who developed spontaneous dislocations in the foot or ankle are presented. All were shown to have diabetic neuropathy. This previously unreported condition can occur with a short history of diabetes. Some cases can be managed without operation, though arthrodesis probably offers the best chance of obtaining a stable foot of satisfactory shape

A prospective study of 33 civilian parachutists with 41 injuries is presented. Because the training for civilians is less rigorous than that for military parachutists, the hospital admission rate for severe injuries was high (81.8%). Most injuries occurred during landing and the ankle was most frequently involved. The types and possible mechanisms of injury are discussed, as well as recommendations for modifying the civilian training programme

Sixteen severely haemophilic patients have undergone arthrodesis of one joint of the lower limb in the period 1966 to 1976. There have been nine arthrodeses of the knee and seven of the ankle. The follow-up period was from nine months to eight years. The arthrodeses were secured by internal fixation. The method was not without complications, but a satisfactory bony union resulted in all cases without further surgical intervention

We compared two conservative methods of treating Weber B1 (Lauge-Hansen supination-eversion 2) isolated fractures of the lateral malleolus in 65 patients. Treatment by immediate weight-bearing and mobilisation resulted in earlier rehabilitation than immobilisation for four weeks in a plaster cast. There was no significant difference in the amount of pain experienced or in the requirement for analgesics and early mobilisation was not associated with any complications. We therefore advocate early mobilisation for these stable ankle fractures

The results of 10 patients with severe rigid drop-foot corrected by the Lambrinudi triple arthrodesis were studied. The average amount of correction was 47 degrees, as evaluated from standing radiographs taken before and after operation. Radiological features of osteoarthritis and of flattening of the talus were common, but the feet were painless when reviewed at an average of 70 months later. A satisfactory range of movement was obtained at the ankle joint

We report a new method of ankle arthrodesis which combines an anterior approach with a dowel technique of bone grafting and screw fixation. In 20 ankles of 20 patients, ten with osteoarthritis, eight with rheumatoid arthritis and two others, we achieved 19 solid bony fusions and one painless fibrous ankylosis. The average time to union was 12.5 weeks. Patient satisfaction was high and the functional results were as good as for other reported methods, with fewer complications

1. The cases of four children who presented with bowing or pseudarthrosis of the fibula only, are described. 2. There is a gradation in the severity and significance of this condition. There may be fibular bowing without fibular pseudarthrosis; fibular pseudarthrosis without ankle deformity; fibular pseudarthrosis with deformity but without the late development of tibial pseudarthrosis; or fibular pseudarthrosis with the late development of tibial pseudarthrosis. 3. Proper management is dependent on a knowledge of this range of conditions

1. Previous papers on the subject of the os trigonum are reviewed. 2. Evidence is produced to show that the posterior part of the talus normally develops from separate centres. 3. An explanation is given for the presence in adults of separate ossicles (the so-called os trigonum) in one or both ankles and for the variety of shapes adopted by them. 4. Contrary to opinions expressed by previous writers, these ossicles may give rise to symptoms

A method is described which provides standardised reproducible radiographic images of the lower limb. Anteroposterior and lateral radiographs are digitised and processed by computer to provide graphic/numeric displays of angles and linear measurements, relating the centre points of the hip, knee, and ankle. Two cases illustrate how surgical planning is facilitated when standardised data are available. These data confirm the close relationship between postoperative limb alignment and positioning of prosthetic elements

An anteroposterior radiograph of the leg to include the hip and ankle, taken with the patient standing, provides an estimate of the line of load-bearing at the knee. Gait analysis may be used to determine the way in which the load in the knee is shared between the medial and lateral compartments during normal walking. A comparison of the results from the two methods, carried out on a group of 47 patients, led to the conclusion that both calculations are required for the successful outcome of a tibial osteotomy or a total arthroplasty

1. An account is given of a family in which five members in three generations were affected by osteochondritis involving the hips, in three cases bilaterally. 2. One patient showed aseptic osseous necrosis of the epiphyses of the ankles and fingers. 3. The differential diagnosis between Perthes' disease and multiple epiphysial dysplasia is discussed, but it is not certain into which category these patients fall. 4. The assistance of a family history and skeletal survey in diagnosis is illustrated

Five children with congenital pseudarthrosis of the tibia treated by free vascularised fibular grafts were followed up until skeletal maturity. The ipsilateral fibula was used in four cases, the contralateral fibula in one. All our cases achieved bone union, but leg length discrepancy, atrophy of the foot and ankle stiffness were frequent complications, due perhaps to the many previous operations. Vascularised fibular grafting might achieve better results if it were done as the primary procedure

We report the results of a three-year study of bifocal fractures of the tibia and fibula, excluding segmental shaft fractures. In our whole series, these formed 4.7% of all tibial diaphyseal fractures. We describe three groups: bifocal fractures of both the proximal and the distal joint surfaces, fractures of the shaft and tibial plateau, and fractures of the shaft and ankle. These groups of fractures had different characteristics and prognoses. We discuss treatment protocols for each of these three groups

Congenital vertical talus was diagnosed in 15 feet of 10 children, and was treated by operative reduction. Forefoot deformity was corrected first, using anterolateral soft-tissue release on 11 feet, and manipulation alone in four feet. After prolonged immobilisation in plaster the affected feet had posterior release at the ankle and elongation of the calcaneal tendon. Clinical and radiographic examination at follow-up 15 months to 21 years later showed that a satisfactory outcome had been achieved in 12 of the 15 feet

Between 1993 and 2000 we implanted 200 cementless, mobile-bearing STAR total ankle replacements. None was lost to follow-up for reasons other than the death of a patient. The mean follow-up was for 46 months (24 to 101). A complication requiring further surgery developed in eight ankles and 14 were revised or fused. The cumulative survival rate at five years was 92.7% (95% CI 86.6 to 98.8) with time to decision to revision or fusion as an endpoint. The most frequent complications were delayed wound healing and fracture of a malleolus. These became less common with experience of the operation. The radiological appearance of the interface of the tibial implant was significantly related to its operative fit and to the type of bioactive coating
