Aims

In our unit, we adopt a two-stage surgical reconstruction approach using internal fixation for the management of infected Charcot foot deformity. We evaluate our experience with this functional limb salvage method.

Aims

To investigate whether idiopathic osteonecrosis of the femoral head (ONFH) is related to impaired osteoblast activities.

Aims

Complex fractures of the femur and tibia with associated severe soft tissue injury are often devastating for the individual. The aim of this study was to describe the two-year patient-reported outcomes of patients in a civilian population who sustained a complex fracture of the femur or tibia with a Mangled Extremity Severity Score (MESS) of ≥ 7, whereby the score ranges from 2 (lowest severity) to 11 (highest severity).

1. Three cases of traumatic anuria following muscle ischaemia ("crush syndrome") are reported. 2. The pathogenesis and treatment of the condition are discussed. 3. A scheme of management directed to the prevention of renal failure is proposed

1. Two cases of arterial damage complicating shoulder injuries are reported. 2. The treatment is described and the importance of early diagnosis is stressed. 3. Operation was indicated in both cases by developing ischaemia in spite of conservative measures

Forty-five Chinese patients had below-knee amputation by a sagittal flap technique; 84% for ischaemia. Satisfactory healing was obtained in over 90%, but complications and failure were more common in patients with diabetes mellitus. A modified sagittal flap is recommended

1. Three cases of premature epiphysial closure at the knee complicating prolonged immobilisation for congenital dislocation of the hip are described. 2. The etiology of this complication is briefly discussed, and it is suggested that relative ischaemia of the epiphysial plates is the most likely cause

1. A case of persistent exercise ischaemia affecting the anterior tibial group of muscles is described. 2. Pathogenesis and treatment are discussed. Decompression of the anterior tibial compartment is required if the patient is unwilling to give up whatever activity causes the exercise pain

Aims

The main objective of this study is to analyze the penetration of bone cement in four different full cementation techniques of the tibial tray.

Cartilage formation was provoked in the skull vault of the young rat by making multiple incisions, and scraping the periosteum to reduce the blood supply to the injured area. The hypothesis that ischaemia induces osteogenic cells to produce cartilage in the course of fracture repair thus receives experimental support

Torsion and subsequent ischaemia is a well-recognised cause of symptoms and morbidity in general surgery. We present three cases of solitary pigmented villonodular tumours of the knee which were found to have undergone torsion. We believe these to be the first intra-articular tumours in which torsion has been reported

1. A small mobile oxygen chamber is described which overcomes some of the disadvantages of using high pressure oxygen therapy in cases of general or local anoxia. 2. A case of limb ischaemia following an open fracture of the tibia and fibula is described in which such a method of treatment was used

We perfused 16 human femora with a 50% barium sulphate suspension and studied the intra-osseous vessels by microfocal radiography and histology. There were few anastomoses between the vessels of the greater trochanter and those of the adjacent cancellous bone of the shaft. Ischaemia of the trochanter may contribute to nonunion after trochanteric osteotomy

1. A case of Volkmann's ischaemic contracture, in which function was greatly improved by a muscle slide operation, is described. 2. The possibility of regeneration of muscle after ischaemia is reviewed in the light of recent research. 3. Injection experiments suggest that the forearm flexors, like the gastroenemius,are supplied by end arteries

1. Exercise ischaemia in athletes with chronic pain over the postero-medial border of the tibia is described. 2. Fasciotomy of the compartment of the deep flexor muscles as a treatment of "shin splints" is recommended. 3. In eleven patients the symptoms were completely relieved and the athletes were able to start effective training within four weeks

Disarticulation has been carried out in ten ankles in nine patients in whom it was not possible to use a heel flap. Four patients were able to walk with a prosthesis which gave satisfactory function. In five who were bedridden, healing was achieved and was of sufficient quality to allow transfers. There was no operative morbidity or mortality. This technique can be used instead of a transtibial amputation if necrosis or ischaemia of the heel is a contraindication to conventional Syme’s amputation

We report the management and outcome of 35 lower limb fractures with associated severe vascular injuries treated over a 15-year period. Limb survival was related to the period of ischaemia. Management of the fractures by immediate open reduction and internal fixation was associated with a higher amputation rate than either external fixation or simple splintage, particularly for upper tibial injuries. External fixation is recommended as the method of choice for the stabilisation of the skeletal injury. A selective policy is advised for fasciotomy

1. The tarsal tunnel syndrome is a clinical entity and is probably more often encountered than is recognised. 2. The cause is unknown but is probably like that responsible for the carpal tunnel syndrome. Experimental evidence suggests that the sensory symptoms in both these conditions are due to localised ischaemia of the nerve within the fibro-osseous tunnels, and that later structural changes are responsible for motor paralysis. 3. Relief of symptoms is complete if decompression of the posterior tibial nerve is performed before the onset of motor involvement

Aims

Open discectomy (OD) is the standard operation for lumbar disc herniation (LDH). Percutaneous endoscopic lumbar discectomy (PELD), however, has shown similar outcomes to OD and there is increasing interest in this procedure. However despite improved surgical techniques and instrumentation, reoperation and infection rates continue and are reported to be between 6% and 24% and 0.7% and 16%, respectively. The objective of this study was to compare the rate of reoperation and infection within six months of patients being treated for LDH either by OD or PELD.
