Joint deformity secondary to extensive haemangiomatous involvement of the soft tissues has been well described and is easy to diagnose. If the haemangioma is small, localised and within the belly of a muscle the diagnosis is more difficult. In equinus deformity of obscure aetiology localised calf tenderness may be the only diagnostic sign. Three children with equinus deformity caused by a small haemangioma in the calf muscles were treated by simple excision with satisfactory results

1. The clinical, radiological, operative and histological features of twelve aneurysmal bone cysts are recorded. 2. Attention is drawn to atypical features, and the problem of diagnosis is discussed. 3. It is recommended that treatment should be complete excision, except where this would interfere with function. 4. Various theories on pathogenesis are considered and favour given to the view that these cysts result from a local change in haemodynamics occurring possibly in a pre-existing lesion

1. Tarsal coalition often presents with the clinical picture of a peroneal spastic flat foot, but may present with a painful varus foot and spasm of the tibial muscles. 2. Three cases of tibialis spastic varus foot are described with a calcaneo-navicular bar as the associated anomaly. 3. Complete excision of the bar with interposition of the origin of the extensor digitorum brevis muscle appears to be a satisfactory method of treatment when carried out at a sufficiently early age

In 11 patients juxta-articular osteosarcoma around the knee was treated by intraepiphyseal excision of the tumour and reconstruction of the bone defect by distraction osteogenesis. Preoperative and postoperative chemotherapy was given to eight patients with high-grade tumours. The articular cartilage of the epiphysis and a maximum of healthy soft tissues were preserved. Distraction osteogenesis was then carried out. The mean gain in length was 9.7 cm. Full function of the limb was preserved in all except one patient, with a mean follow-up of 53.8 months. Treatment of juxta-articular osteosarcomas around the knee with joint preservation and biological reconstruction using distraction osteogenesis can give excellent functional results

Twenty-nine bone defects caused by chronic osteomyelitis have been treated by radical excision of necrotic bone followed by packing the cavities with cancellous homografts held in position by a fibrin sealant. At follow-up three years after operation all except one had healed, though one case had needed a repeat operation. Good incorporation and remodelling of the grafts was observed even when the osseous bed was severely sclerosed

We report the use of a new approach for elbow arthroplasty in 58 cases over a 20-year period. A wide exposure, obtained by elevating the triceps attachment and dividing the radial collateral ligament, allows the excision of diseased tissue, articular irregularities and osteophytes. Normal anatomy is restored and active mobilisation can be started 10 days after operation. Good or fair results, with over 70 degrees of joint movement, were achieved in 88% of cases

Sixty-five total hip arthroplastics were reinserted after sepsis around the hip, positive cultures being obtained from fifty-six. Although 65 per cent of patients still have their implant in position, only sixteen of sixty-five (25 per cent) show an excellent or good result on a Harris rating. Twenty-three of sixty-five (35 per cent) subsequently required an excision arthroplasty. The indications and contraindications for this procedure are given

An attempt to produce scoliosis in young baboons by excision of the heads of ribs failed in thirteen growing animals observed for up to a year after operation. Other investigators have failed to produce scoliosis in primates by similar and other techniques that had successfully produced scoliosis in quadruped animals. The possible reasons for this are discussed, especially in the light of clinical trials that are being carried out with techniques transposed from the quadruped experimental animal to the scoliosis clinic

1. Two cases of haemangioma of the patella are reported. 2. In one case pain alone brought the patient for treatment; in the other, a pathological fracture was the first symptom. 3. In neither case was a firm diagnosis made before excision and histological examination of the patella. 4. In each case a good result followed removal of the patella: this is probably the best method of treatment. 5. The literature relating to haemangioma of bone and to tumours of the patella is briefly reviewed

Between 1994 and 1999, we treated six patients with avascular necrosis of the talus by excision of the necrotic body of the talus and tibiocalcaneal fusion using an Ilizarov frame. This was combined with corticotomy and a lengthening procedure. Shortening was corrected in all patients except two, who were over 60 years of age. All patients had previous operations which had failed. All achieved solid bony fusion, with five out of six having either a good or an excellent result. We conclude that this is an effective reconstructive technique which gives a good functional result

We report 12 patients with infiltrating muscular lipomas of the lower limbs all treated by wide resection. During follow-up averaging seven years, the tumour recurred in five patients. Our results and those reported by others suggest that, in order to avoid recurrence, this tumour, although benign, should be treated by total excision of the muscle or by compartmental resection. Hormonal imbalance was suspected in 9 of the patients but an oestrogen receptor analysis of the histological samples proved negative

Six patients with severe haemophilic arthropathy of the elbow have been treated by limited excision arthroplasty using a sheet of silicone rubber as an interposition membrane. There were no complications. The symptoms and signs before and after operation have been assessed using the grading system advocated recently by the World Federation of Haemophilia. In all cases there was relief of pain and increased movement. Moreover, the subsequent incidence of spontaneous haemorrhage into the elbow has been reduced with considerable cost benefit

1. A case of late infection about a total knee prosthesis secondary to urinary tract infection is described, indicating that haematogenous spread of infection to a prosthetic joint can occur. 2. The prophylactic use of antibiotics to cover surgical and dental treatment and the energetic treatment of intercurrent infection are urged for patients with artificial joints. 3. Any conservative treatment of established infection in such cases should include complete excision of all necrotic material from the joint

Internal fixation with a trifin nail after displacement osteotomy of the femur permits reduction of external splintage to a degree that any patient can tolerate with ease; it also eliminates the problem of the stiff knee. The method has been used successfully for recent and old fractures of the femoral neck, for post-irradiation fractures, for failed nailing operations or arthroplastics, for osteoarthritis, for rheumatoid arthritis, for old congenital dislocations and subluxations, and to stabilise the hip after excision of the head and neck to create a pseudarthrosis

Aims

The purpose of this study was to compare the effectiveness of surgical repair to conservative treatment and subacromial decompression for the treatment of chronic/degenerative tears of the rotator cuff.

A new method of treating large bony defects of the proximal femur is described. The defect is filled with a large vascular-pedicled bone graft from the iliac crest. The graft, being nourished by the deep circumflex iliac vessels, remains viable and therefore induces rapid healing of the bone. This method of bony replacement encourages adequate excision of potentially malignant bone lesions and provides sufficient mechanical support to allow early walking. Six clinical cases are presented to illustrate its application

Between 1971 and 1976 eight patients underwent excision of the carpal lunate for pain from Kienbock's disease. The bone was replaced by a silicone rubber implant. An average of 84 months had elapsed when they were reviewed in December 1980. All eight were very satisfied with their operations. Objectively, the clinical results were good, but radiographs showed the presence of degenerative change in the region of the wrist and alteration of the position of the prosthesis on ulnar deviation of the hand. No implant has had to be removed

Twenty patients with an average age of eighteen and a half years sustained osteochondral fractures of the lateral femoral condyle as the result of a sudden twist and valgus strain to the straight or almost straight knee. All the patients felt sudden pain at the moment of injury, all had a haemarthrosis, and yet the fracture escaped early diagnosis in one-third of the cases. Internal fixation of the fragment with early mobilisation is recommended if the diagnosis is made within two weeks of injury, and excision of the fragment if it is only later identified

An operation for chronic prepatellar bursitis is described in which only the posterior wall of the bursa is excised, thus preserving, undamaged, healthy and normally sensitive skin. This procedure is easier and less traumatic than complete excision of the bursa and results in fewer complications. It is suggested that removal of tha anterior wall of the bursa results in unnecessary and harmful interference with the underlying skin. The operation described gives a good functional and structural result; leaving the anterior wall of the bursa does not predispose to recurrence

Eighteen patients with acute dislocation of the patella had associated osteochondral fractures. This fracture complicates approximately 5% of all acute dislocations of the patella occurring in children. Three types of fracture patterns were noted. All patients who were treated by immediate arthrotomy and excision or replacement of the osteochondral fragment and repair of the acute dislocation of the patella made an uneventful recovery with no recurrence of the dislocation. In those patients in whom the osteochondral fragment was removed but with no repair the dislocation recurred
