1. Radiological criteria in the diagnosis of congenital dislocation of the head of the radius are suggested. 2. Some of the radiographic features described as characteristic of congenital dislocation of the head of the radius may be found also in post-traumatic dislocation of the radial head

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

1. Twenty cases of mycetoma pedis are described. 2. Most patients had the disease in an early stage and were cured by simple excision. 3. The importance of early diagnosis and treatment in order to avoid amputation is emphasised

1. Three cases of hereditary sensory neuropathy are reported. 2. Neuropathic destruction of joints and chronic infected ulcers are the primary problems of management. 3. This entity must be considered in the differential diagnosis of trophic ulcerations of the extremities

We reviewed 16 patients with salmonella osteitis or septic arthritis. All patients were immunologically normal and none had a history of typhoid fever. We discuss the importance of obtaining a bacteriological diagnosis and provide guidelines on the duration of antibiotic treatment

1 . A case of plantar Dupuytren's disease in a woman aged twenty-three is described. 2. A review of the literature has shown that the histology and rapid recurrence have led to an erroneous diagnosis of fibrosarcoma and treatment by amputation on several occasions

We report a patient who developed an aortic pseudoaneurysm in the L3–L4 disc space after lumbar disc surgery. The diagnosis was made by MRI and aortography, and repair using a prosthetic graft and anterior fusion was successful. We discuss the predisposing factors, the clinical picture and management of vascular injuries during disc excision

1. A case of solitary myeloma of the clavicle is reported. The patient remained well, without signs of dissemination, twenty-four years after excision of the clavicle. 2. Solitary myeloma is rare; the diagnosis depends upon thorough investigation and prolonged follow-up

1. The appearance of arthrographs of healthy and of injured ankles are described on the basis of experimental and clinical studies. 2. Arthrographic appearances have been correlated with findings at operation. 3. Arthrography is a valuable method of investigation for the accurate diagnosis of injuries about the ankle

1. A case of massive osteolysis of the right humerus is described. Diseased bone was resected leaving only the lower part of the humerus. The resected bone was replaced by a titanium prosthesis. 2. The diagnosis, etiology, prognosis and treatment of the condition are briefly discussed

1. Three cases of osteochondromatosis of the hip joint are described. 2. Attention is drawn to the diagnostic importance of erosions at the junction of head and neck of the femur, and the conical shape of the femoral neck. 3. Arthrography is of particular value in diagnosis when the loose bodies are radio-translucent

We report a 72-year-old patient with thoracic myelopathy due to isolated ossification of the ligamentum flavum at T9-T10. Severe paraparesis had developed before the lesion was identified when thinning of a segment of the lower thoracic spinal cord was suspected on a second MRI examination. The diagnosis was then established by CT

Osteochondral fractures of the talus are uncommon. They are classified according to Berndt and Harty, as progressing in severity through four stages. This classification, however, does not address extra-articular extrusion of the osteochondral fragment. We report an osteochondral lesion of the talar dome which presented as an extruded extra-articular fragment in a closed injury of the ankle. This type of lesion may offer a continuation to the four original stages. Clinicians should be aware that this pattern of fracture can occur, and thus allow a more accurate diagnosis and the provision of some aid in the treatment of these injuries

We present a 26-year-old athlete with severe low back pain associated with a fracture of a lumbar pedicle and contralateral spondylolysis. The difficulties of diagnosis are discussed together with the subject of segmental pain referral. A technique of operative management is described involving instrumentation of the symptomatic level alone

1. The symptoms, signs and treatment of three patients with a posterior dislocation of the clavicle are described. 2. The value of tomography in confirming the diagnosis is outlined. 3. Certain experimental work has been done in an attempt to determine the factors necessary to produce this dislocation

Pyomyositis of the obturator muscles is a rare condition, characterised by pain in the hip and features of systemic infection. It may follow minor trauma to the hip, sometimes in the presence of an apparently innocuous infective source. All previously reported cases have been diagnosed conclusively on the initial CT or MR scan. We present a case of obturator pyomyositis in a 21-year-old football player in which the first MR scan was misleading. A radiolabelled, white blood cell scan was also negative and the resultant delay in diagnosis proved dangerous. The crucial importance of careful and repeated clinical examination is emphasised

1. A case of traumatic aneurysm of the descending genicular artery complicating elective operation on the knee joint is reported. 2. The aneurysm was mainly intra-articular, presenting as a pulsating haemarthrosis soon after operation. 3. The pathogenesis, symptomatology, diagnosis and management are briefly discussed

Aims

The sacrum is frequently invaded by a pelvic tumour. The aim of this study was to review our experience of treating this group of patients and to identify the feasibility of a new surgical classification in the management of these tumours.
