Pseudarthrosis of the radius treated by free vascularised bone graft.

We report a case of pseudarthrosis of the radius successfully treated by free vascularised bone grafting. After a comprehensive review of the literature, we recommend this as the treatment of choice in this condition. We also report the use of callus distraction of an incorporated vascularised bone graft to achieve bone lengthening.

Cystic degeneration of fibrous dysplasia masquerading as sarcoma.

An area of fibrous dysplasia of bone may undergo rapid enlargement which may be due to either cystic degeneration or malignant transformation. These complications may be clinically and radiologically indistinguishable and, unless both are borne in mind, incorrect management may follow. Magnetic resonance imaging was used in one of our cases and was the only imaging modality to demonstrate the true nature of the condition.

Congenital dislocation of the hip presenting after the age of three years. A long-term review.

We reviewed the cases of 38 children with 45 congenitally dislocated hips who presented for primary treatment after the age of three years. Of these, 34 hips were managed by the 'direct approach' of Somerville and Scott (1957); 14 of these required secondary operations for subluxation, often with a poor outcome. Eleven hips were treated by combined pelvic and femoral osteotomy which, in general, gave good results. At a mean follow-up of 16.7 years, 80% of the whole series had a good or excellent clinical result and 51% were good or excellent radiologically. Simultaneous correction both above and below the hip is considered to be the best treatment for the older child with congenital hip dislocation.

Why do children break their arms?

Over a 1-year period the mode of fracture of the long bones of children's upper limbs was analysed. There were 277 fractures and 4 dislocations recorded. The most common fractures were of the distal radius and ulna. Most injuries were due to falls from a low height but those from a high fall necessitated hospital admission most frequently. Preventative measures are discussed.

Bilateral avulsion fractures of the cranial margin of the scapula.

Avulsion of the cranial margin of the scapula is a rare injury. A case of bilateral avulsion fractures is reported. The postulated mechanism of injury is a powerful contraction of the omohyoid muscle avulsing its insertion. Conservative management was successful.

The risks of injury in public ice skating.

A prospective survey has been made of the injuries to members of the public attending a well established ice rink in a major city. Comparison is made with series in the literature reporting high levels of injuries, with corresponding demands on local hospital services, from newly established ice rinks. The main conclusion is that demands on hospital services have been markedly reduced for the well established rink, with corresponding savings in health service resources.

Late femoral osteotomy in congenital dislocation of the hip.

We describe 95 patients with previously treated congenital dislocation of the hip who underwent femoral osteotomy after the age of five years. The commonest indication for surgery was progressive uncovering and subluxation of the femoral head; other reasons were coxa vara, long leg dysplasia and persistent anteversion. Femoral osteotomy for uncovering of the femoral head (Severin Grade III) in this age group gave good results at maturity only when the acetabular angle was less than 25 degrees before operation. Femoral osteotomy alone was inadequate for true subluxation of the hip (Severin Grade IV).

The use of semipermeable dressings in fingertip injuries.

A randomised prospective trial was carried out to compare the use of semipermeable and petroleum gauze dressings in fingertip injuries. The results demonstrate advantages in the use of semipermeable dressings.

Ice-skating injuries.

The range of injuries sustained at an ice-rink and presented to an Accident Service department is described. A total of 203 patients with 222 injuries presented themselves during a 2-month period. There were 103 noteworthy injuries, including 61 fractures, 2 dislocations and 2 severed tendons, but the commonest injuries were wounds, sprains and bruises. Beginners appear to be more prone to injury than experienced skaters. In addition to using well-fitting skate-boots to protect the ankle, some injuries could be avoided by wearing elbow and knee pads, and a thick pair of gloves. The number of injuries compared with the total number of skaters was small but produced a noteworthy increase in the workload of the Accident Service.
