Aims

A pilon fracture is a severe ankle joint injury caused by high-energy trauma, typically affecting men of working age. Although relatively uncommon (5% to 7% of all tibial fractures), this injury causes among the worst functional and health outcomes of any skeletal injury, with a high risk of serious complications and long-term disability, and with devastating consequences on patients’ quality of life and financial prospects. Robust evidence to guide treatment is currently lacking. This study aims to evaluate the clinical and cost-effectiveness of two surgical interventions that are most commonly used to treat pilon fractures.

Aims

Infected and deformed neuropathic feet and ankles are serious challenges for surgical management. In this study we present our experience in performing ankle arthrodesis in a closed manner, without surgical preparation of the joint surfaces by cartilaginous debridement, but instead using an Ilizarov ring fixator (IRF) for deformity correction and facilitating fusion, in arthritic neuropathic ankles with associated osteomyelitis.

Aims

The aim of this study is to test the hypothesis that three grades of sagittal compensation for standing posture (normal, compensated, and decompensated) correlate with health-related quality of life measurements (HRQOL).

Aims

The primary aim of this study was to address the hypothesis that fracture morphology might be more important than posterior malleolar fragment size in rotational type posterior malleolar ankle fractures (PMAFs). The secondary aim was to identify clinically important predictors of outcome for each respective PMAF-type, to challenge the current dogma that surgical decision-making should be based on fragment size.

Aims

The aim of this study was to report the results of three forms of reconstruction for patients with a ditsl tibial bone tumour: an intercalary resection and reconstruction, an osteoarticular reconstruction, and arthrodesis of the ankle.

Aims

This study aims to investigate the effects of posterior tibial slope (PTS) on knee kinematics involved in the post-cam mechanism in bi-cruciate stabilized (BCS) total knee arthroplasty (TKA) using computer simulation.

1. A retrospective clinical and radiological study has been undertaken of forty-six cases of closed Dupuytren fracture-dislocation of the ankle joint in adults. 2. The final results are analysed with reference to the methods of treatment employed. 3. The problems of this injury are discussed referring both to the results of this investigation and to the past literature

Charcot osteoarthropathy of the foot is a chronic and progressive disease of bone and joint associated with a risk of amputation. The main problems encountered in this process are osteopenia, fragmentation of the bones of the foot and ankle, joint subluxation or even dislocation, ulceration of the skin and the development of deep sepsis. We report our experience of a series of 20 patients with Charcot osteoarthropathy of the foot and ankle treated with an Ilizarov external fixator. The mean age of the group was 30 years (21 to 50). Diabetes mellitus was the underlying cause in 18 patients. Five had chronic ulcers involving the foot and ankle. Each patient had an open lengthening of the tendo Achillis with excision of all necrotic and loose bone from the ankle, subtalar and midtarsal joints when needed. The resulting defect was packed with corticocancellous bone graft harvested from the iliac crest and an Ilizarov external fixator was applied. Arthrodesis was achieved after a mean of 18 weeks (15 to 20), with healing of the skin ulcers. Pin track infection was not uncommon, but no frame had to be removed before the arthrodesis was sound. Every patient was able to resume wearing regular shoes after a mean of 26.5 weeks (20 to 45)

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

Chronic instability of the ankle is frequently due to disruption of the fibres of the anterior talofibular ligament and the anterolateral capsule. This allows momentary subluxations at the ankle joint; the talus tilts into an abnormal varus position and rotates forwards and inwards about a vertical axis which passes through the medial malleolus. The use of a free tendon graft to reconstruct the anterior talofibular ligament restores the stability of the ankle without restricting movement at the subtalar level

1. A method of treatment of posterior malleolar fracture is described which restores the proximal surface of the ankle joint to its normal position. 2. Reduction is achieved with a special clamp and the position held with a strong plate. Early ankle movements may therefore be encouraged without fear of redisplacing the fracture. 3. Perfect reduction is necessary to avoid the later onset of arthritis, and this was achieved in five of six patients reported

1. A clinical and radiological survey has been made of the families of thirty-one patients with peroneal spastic flat foot and tarsal coalition (twenty-seven calcaneo-navicular, four talo-calcaneal). 2. Thirty-nine per cent of ninety-eight first degree relatives were found to have some type of tarsal coalition. 3. A surprise finding was that not one of the first degree relatives had ever had symptoms referred to the tarsus. 4. No case of "ball and socket" ankle joint or of carpal coalition was found in this series

1 . This case of post-traumatic osteochondritis of the lower tibial epiphysis is important because the condition is rare. 2. The similarity to osteochondritis in other sites dating from a single injury is noted. 3. The ankle joint bears more body weight per surface area of articular cartilage than other weight-bearing joint surfaces. It is of interest that regeneration took place in spite of the fact that the child continued to bear weight and that the joint was immobilised for only two months, beginning four months after the original injury

1. Further consideration has been given to the lateral rotation which occurs at the ankle joint in uncorrected club feet. 2. Medial rotation osteotomy of the tibia may be used to restore more normal alignment to the hind foot at the expense of an increase in varus of the forefoot, which must be corrected at a second operation. 3. The early results in seven feet treated in this manner are reported. 4. We hope that this paper will be regarded more as a contribution to the understanding of the anatomy of uncorrected club foot than as advocacy of a new method of surgical treatment

1. By reducing the viscosity of the synovial fluid within the ankle joints of rabbits and then subjecting these to prolonged exercise, wear and tear of articular cartilage can be consistently produced. 2. This finding is an indirect confirmation of the view that fluid film lubrication is an important factor in the mechanical efficiency of joints. 3. The special properties of synovial fluid and articular cartilage that allow fluid film lubrication to exist within joints that are, in effect, slowly moving, heavily loaded, reciprocating bearings are discussed. They account for the remarkable resistance to wear and tear exhibited by synovial joints under physiological conditions

Fourteen cases of pseudarthrosis of the tibia in childhood presented at a hospital in Burma over a period of eight years. The ages of the patients ranged from one month to seventeen years. Nine were treated by a pointed graft driven into the medullary cavity of the distal tibia, and usually across the ankle joint into the body of the talus, before fixation to the proximal tibia. In six of the nine union was secured, but one case required a second grafting. Transarticular segments of graft showed a marked tendency to undergo absorption. No significant deformity was observed to follow central penetration of the growth plate and epiphysis of the lower tibia

We reviewed 63 patients with fractures of the distal tibial metaphysis, with or without minimally displaced extension into the ankle joint. The fractures had been caused by two distinct mechanisms, either a direct bending force or a twisting injury. This influenced the pattern of the fracture and its time to union. All fractures were managed by statically locked intramedullary nailing, with some modifications of the procedure used for diaphyseal fractures. There were few intra-operative complications. At a mean of 46 months, all but five patients had a satisfactory functional outcome. The poor outcomes were associated with either technical error or the presence of other injuries. We conclude that closed intramedullary nailing is a safe and effective method of managing these fractures

1. Twenty cases of tarso-metatarsal joint injury have been studied with regard to the mechanism of injury, and experiments have been done on cadavers to confirm clinical impressions. 2. Injuries of the tarso-metatarsal joints occur by direct and indirect mechanisms, the latter being more common. 3. Indirect injuries occur in at least two ways-namely, acute abduction of the forefoot and plantar-flexion of the forefoot. 4. Most of the indirect injuries occur when the ankle joint is in a plantar-flexed position. 5. Whereas this foot injury once gained prominence on the field of battle amongst cavalrymen, it is currently associated with the motor car, the step ladder, the toboggan, the joy-rider, and commonly the simple misguided step
