1. Two patients with bilateral pes cavus and lymphoedema are reported. Lymphography confirmed the existence of lymphatic insufficiency in both cases. In both there was evidence of hereditary factors in the etiology. 2. This familial syndrome appears not to have been previously reported

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. A case of dysphagia caused by a large cervical osteophyte is presented. 2. The literature from 1960 is reviewed, with special reference to the cases in which operation was done, and etiological factors are considered. 3. Excision of the osteophyte should in most cases be combined with fusion

The usual causes of pain after total knee replacement are well known, but there are a small number of patients in whom its aetiology is obscure. We report three patients with a specific pain syndrome caused by hypertrophic fibrous tissue in the intercondylar notch. Excision of this tissue relieved the symptoms completely

The Gorham-Stout Syndrome (Gorham’s massive osteolysis) is a rare condition in which spontaneous, progressive resorption of bone occurs. The aetiology is poorly understood. We report six cases of the condition and present evidence that osteolysis is due to an increased number of stimulated osteoclasts. This suggests that early potent antiresorptive therapy such as with calcitonin or bisphosphonates may prevent local progressive osteolysis

Two cases of idiopathic avascular necrosis of the scaphoid are reported and it is suggested that the aetiology could be the same as that recently described for Keinboeck's disease by Beckenbaugh et al. (1980). The condition described in this paper is a different entity from that described by Preiser (1910), which was probably not an osteochondritis but an undiagnosed fracture

1. A case of Behçet's syndrome in which the main complaint was severe pain in the manubrio-sternal joint is described. Arthrodesis relieved the pain. 2. Histological material from a mouth ulcer and from the manubrio-sternal joint showed non-specific inflammatory changes but failed to throw light on the etiology

1. Idiopathic calcification of articular cartilages is described in a Jamaican woman of thirty-one years who had intermittent joint pains for ten years and who had evidence of past gonococcal infection. She was otherwise normal. 2. The etiology of the condition is unknown. 3. Previous literature is reviewed

Thirty-four bony specimens of isthmic spondylolysis were examined and, in a significant number (32%), stenosis of the intervertebral foramen was noted. Although not emphasised in previous reports, this finding may be an important factor in the aetiology of nerve root compression when this is associated with spondylolysis and spondylolisthesis. Anatomical guidelines for adequate surgical decompression are suggested

1. Thirteen cases of "pseudorheumatoid" nodules are presented. Eight of these have been observed for three months to eleven years. 2. Histologically the nodules were identical to those that may be associated with rheumatoid arthritis or rheumatic fever. 3. No evidence of systemic disease was found. 4. The etiology is not clear but the prognosis is good

1 . Three cases of triphalangeal thumb are described in three generations of a Bantu family. In the youngest member both thumbs were affected; in his mother and grandfather only one thumb was abnormal. 2. The literature is reviewed and the etiology of the anomaly is discussed. 3. Attention is drawn to the hereditary tendency of this condition

Premature epiphysial closure is an infrequent complication of Perthes' disease. Twenty-two patients with this condition are reviewed, three of whom were bilaterally affected. The aetiology, radiographic features and effect on function are discussed. The incidence of this complication can be reduced by an awareness of the clinical and radiographic signs which contra-indicate treatment by upper fermoral osteotomy

The findings in a child with bilateral congenital dislocation of the hips who died shortly after birth are described. The only significant abnormality present was redundancy of the capsular ligaments and elongation of the ligament of the femoral head. The relationship between the orientation of the femoral neck and of the acetabulum was within normal limits. The significance of these findings in relation to etiology and management are discussed

1. Two cases of rupture of the axillary artery without dislocation of the shoulder or fracture of the neck of the humerus are reported, and the etiology is discussed. 2. The treatment of a ruptured axillary artery is primary repair, and not ligation. 3. In the repair of the artery the complete clearance of distal thrombus is most important; retrograde flushing is advised for this purpose

1. A brief description is given of normal epiphysial growth of the human femur. 2. Some ways in which abnormality of the growth plates may affect the shape and length of the human femur are described. 3. The influence of the blood supply on growth is discussed with particular reference to the etiology and treatment of congenital coxa vara

1. Two cases of deposition of calcium in the medial ligament of the knee are described. Pain was a prominent feature in both. 2. A review of the literature suggests this is an uncommon condition. 3. The condition closely resembles supraspinatus calcification, and the etiology is probably similar. 4. Both cases were treated by operation, with complete relief of symptoms

Eight cases of carpal tunnel syndrome are reported, all of which developed in patients on haemodialysis for chronic renal failure. In each case the arm involved had been used for a fistula. The aetiology of the syndrome in these patients is discussed; it is multifactorial, but related to the sites of arteriovenous fistulae. Decompressing the carpal tunnel provides effective and lasting relief

A review of seventy-one children with sacral anomalies is presented. The aetiology is discussed and a classification of sacral anomalies is suggested, with three groups of patients: agenetic, dysgenetic and dysraphic. The clinical presentation of each group is discussed and the high incidence of congenital visceral and skeletal abnormalities is indicated in the dysgenetic group. The need for constant urological assessment is emphasised, particularly in the agenetic and dysraphic children

1. The clinical, radiological and pathological features in seven cases of subchondral bone cyst are described. 2. Various hypotheses on the etiology of the lesion are discussed. 3. Although the hypothesis of vascular disturbance is thought to be the most attractive one, it is concluded that study of material from much earlier lesions than that hitherto available is essential if any justifiable theory is to be propounded

Osteomyelitis is a rare manifestation of cat-scratch disease in patients who do not have AIDS. The clinical presentation and non-specific subacute course of the disease make diagnosis difficult. We present a child with osteomyelitis of a metacarpal following a dog scratch. Bartonella henselae was found to be the aetiological agent. The bone healed after treatment with antibiotics. Increased awareness and a comprehensive medical history are needed to identify patients with suspected Bartonella henselae osteomyelitis
