Overgrowth of the femur after fracture in childhood. An increased effect in boys.

Forty-four children, treated conservatively for fracture of the shaft of a femur, were studied radiographically to assess the consequent increase in longitudinal growth of the bone. Overgrowth averaged 8.1 mm and was shown to be significantly greater in boys than in girls. Overgrowth did not appear to be influenced by the age of the patient, the type of injury, the type or site of the fracture, the amount of overlap of the fragments or by the handedness of the patient.

An improved technique of intra-operative bone scanning.

Radiopharmaceuticals have been successfully used to detect occult neoplasms and infective lesions. Bone scans using 99mTc-labelled methylene diphosphonate located osteoid osteomas accurately in a series of 30 symptomatic patients. A portable radiation detector system has been designed to help intra-operative localisation and facilitate complete excision of the lesions with minimal damage to normal tissue. A sodium iodide detector with a fibre-optic link was used at first, but a cadmium telluride system has provided a more durable, reliable and sensitive sterilisable probe.

Displaced supracondylar fractures of the humerus in children treated by overhead olecranon traction.

A simple method is described of treating severely displaced, supracondylar fractures of the humerus in children, and the results are reviewed. Treatment involves the use of overhead traction via an olecranon screw and a traction clip. Of 12 children treated in this way, 11 had excellent results with preservation of the normal carrying angle, and no significant loss of movement in any plane. There were no complications of the treatment and no cases of cubitus varus.

Popliteal masses masquerading as popliteal cysts.

Two popliteal swellings, thought initially to be synovial cysts associated with arthritic knees, were found to be unrelated tumours of serious significance. In the presence of neurological signs or a large cyst in association with a noninflammed knee joint a disease other than a simple synovial cyst should be considered.

Rotational displacement of the lower tibial epiphysis due to trauma.

A rare form of injury to the distal tibial growth plate is described. Only two patients with such an injury have been reported previously. The injury, rotational displacement of the distal tibial epiphysis with posterior displacement of the fibula but without fracture, can be reduced easily and appears to have no lasting ill-effects.

Perthes' disease. A study of radiological features.

A study is presented of the radiographs of 68 patients with unilateral Perthe's diseasemtwo types of Perthe's disease are identified: 'fragmenting' and 'non-fragmenting'. The two radiological types of the disease showed no significant differences in the age at diagnosis, the duration of symptoms before diagnosis and the duration of the disease. However, the radiologically-measureable results at healing, in terms of the epiphyseal, acetabular, acetabulum-head and comprehensive quotients were all very significantly worse when fragmentation had developed.

Transposition of the tendon of pronator teres in cerebral palsy.

We have considered the indications for and results of transplanting pronator teres to extensor carpi radialis brevis in cerebral palsy. The operation has some virtue but a very limited application. We achieved satisfactory functional results in six of nine patients and some improvement in one. Two operations failed because of poor selection. In all patients the appearance of the limb was improved.

Scaphoid fractures in children.

Fracture of the carpal scaphoid before skeletal maturity represents 0.34% of all fractures in children and 0.45% of children's upper limb fractures. Seventy-seven children, with a mean age of 11 years (range 8-14 years), suffered a scaphoid fracture in Nottingham, England, between 1977 and 1984 inclusive. Sixty-four of them have been personally reviewed. The mechanism of injury was usually a fall onto the outstretched hand and in the majority was an undisplaced fracture of the distal third of the bone. Immobilization in a scaphoid type of forearm-hand cast led to union in virtually all instances. Nonunion is very rare in treated cases of fresh fracture of the carpal scaphoid.
