We report the cases of three children with chronic injuries of the medial tibial malleolus caused by traction injuries during sport. All three had the triad of swelling of the medial malleolus, tenderness over its anterior part, and pain on forced valgus movement of the foot. Radiographs showed bilateral accessory
We reviewed the outcome, at a mean follow-up of 14 months, of 21 two-column fractures of the acetabulum treated by operation through one or two non-extensile approaches. Eighteen procedures resulted in reduction of the articular surfaces to within 3 mm. The blood loss and operating time when two combined non-extensile approaches were used were similar to those reported for extended acetabular approaches. The incidence of heterotopic
We investigated the clinical, arthroscopic and biomechanical outcome of transplanting autologous chondrocytes, cultured in atelocollagen gel, for the treatment of full-thickness defects of cartilage in 28 knees (26 patients) over a minimum period of 25 months. Transplantation eliminated locking of the knee and reduced pain and swelling in all patients. The mean Lysholm score improved significantly. Arthroscopic assessment indicated that 26 knees (93%) had a good or excellent outcome. There were few adverse features, except for marked hypertrophy of the graft in three knees, partial detachment of the periosteum in three and partial
We have observed congenital hypophosphataemic rickets in two sons of a marriage between first cousins, their mother being clinically and biochemically normal. Both patients are now approaching middle age. In addition to severe childhood rickets and lifelong hypophosphataemia, their disease is characterised by gross osteosclerosis with extraskeletal
Between 1980 and 1988, displacement bone-marrow transplantation was performed on 25 children with Hurler's syndrome (type-1 mucopolysaccharidosis). We describe the musculoskeletal development of 11 of the 12 surviving children and the orthopaedic procedures undertaken to treat progressive thoracolumbar kyphosis, hip subluxation and carpal tunnel syndrome. We found abnormal bone modelling, focal failures of
We describe three children with symptoms of damage to the attachment of an anomalous ossific centre of the lower fibular epiphysis. All three were aged 8 to 10 years at the time of the initial injury, had suffered recurrent ankle sprains and had well localised and consistent tenderness precisely at the site of the anomalous ossific centre. All their symptoms were relieved by excision of the ossicle with reconstitution of the fibular collateral ligament. Whilst a separate secondary centre of
Clinical examinations and radiographic skeletal surveys have been carried out in 15 patients with foetal alcohol syndrome. Fusion of the capitate and hamate bones in the carpus was bilateral in one patient and unilateral in two. All three had accessory
1. Grafts of joint cartilage from immature lambs were used to repair articular cartilage defects in other lambs and in adult sheep. 2. Stability of these grafts in a functional state was found in most for periods up to fourteen months. Although a limited homograft reaction occurred this did not lead to destruction of the cartilage, even though parts of it were well vascularised. 3. The results suggest that the process of endochondral
We describe the histology of a specimen taken from an amputated leg seven months after a 15 cm bone gap in the tibia had been closed by bone transport. Lengthening appeared to have occurred by repeated minor trauma to the bone, with the fractured trabeculae in sufficiently close contact for the repair process to proceed.
A prospective randomised clinical trial was undertaken to compare biodegradable polyglycolic acid pins with standard Kirschner wires used to fix displaced elbow fractures in children. Twenty-four children were enrolled in the trial; 14 had fractures of the lateral condyle of the humerus, eight of the medial epicondyle and two had olecranon fractures. Eleven fractures were fixed with Kirschner wires and 13 with polyglycolic acid pins. Fracture union with full function occurred in all cases within six months. Kirschner wires caused problems including infection in three cases, soft-tissue
We made a prospective longitudinal clinical and radiological study of 18 children diagnosed as having dysplasia epiphysealis capitis femoris. Half the cases were bilateral. Boys were affected five times more often than girls. There were no symptoms or clinical signs in most but some of the bilateral cases had an inconsistent waddling gait. The imaging studies suggest that the cartilaginous proximal femoral epiphysis is hypoplastic, with delayed appearance of single or multiple
In fifty-six patients with ankylosing spondylitis three types of arthroplasty had been performed in ninety-nine hips. Forty-one of the patients were men and fifteen were women, their average age at operation being forty-two years. Primary pseudarthrosis produced well-satisfied patients, but only a fair result in five hips, whereas cup arthroplasty resulted in a poor outcome for eight hips, all of which needed revision. Total replacement of eighty-six hips, however, led to 73 per cent being graded as good or excellent up to ten years later. The main complications were deep infection of five hips, para-articular
1. Thirteen cases of congenital pseudarthrosis of the clavicle conforming to the classical picture are presented, together with five cases of pseudarthrosis occurring for various other reasons, and nine cases of congenital pseudarthrosis that form a special group because there was a strong family history. 2. Treatment, if desired by the patient, is easy, but should be deferred until the age of four or five years. 3. The etiology remains obscure. Our embryological study does not support the theory that the clavicle normally develops from two
The variability in measurement of angles in congenital scoliosis is not known, but it is postulated that it is larger than that in adolescent idiopathic scoliosis due to skeletal immaturity, incomplete
Cleidocranial dysplasia (CCD) is inherited as an autosomal dominant disorder characterised by failure of membranous
We have compared, in rabbits, two techniques of limb lengthening by distraction of the epiphyseal plate using a unilateral external fixation frame. In all cases, 14 mm of symmetrical lengthening without deviation was achieved. With rapid distraction at rates of 1 mm per day (distractional epiphyseolysis) separation of the epiphysis from the metaphysis occurred by day 7, and by day 70 almost complete
1. The results of posterior spinal fusion for paralytic scoliosis in 118 patients have been reviewed after growth had finished. The criteria for skeletal maturity were both clinical and radiological, with emphasis on
1. The process of repair after fracture of the humerus of the growing rat has been studied by histological, histochemical and biochemical methods. 2. Both periosteal and surrounding mesenchymal cells take part in the process of repair. 3. The primary framework of collagen bridging the gap is mainly formed by the mesenchymal cells, while calcification and
