We assessed the outcome after simultaneous multiple operations performed on 18 children with spastic diplegia, with emphasis on the changes in the physiological cost index (PCI) of walking. Fourteen patients had a measurable reduction at one year, but the more severely affected patients took up to two years to reach a new functional plateau. The level of the preoperative PCI allows prediction of the outcome of surgery in terms of reducing the effort of walking, or improving its appearance only. Intrapelvic intramuscular psoas tenotomy produced an improvement of hip flexion deformity in 15 of 17 patients without the loss of muscle power to initiate the swing phase. Fractional lengthening corrected hamstring tightness in 17 cases, and the mean popliteal angle was reduced from 63 degrees preoperatively to 30.2 degrees, with almost complete resolution of the fixed knee flexion deformity present in ten patients. Distal transfer of the rectus femoris, when it was shown to be contracting inappropriately, improved the knee flexion arc during walking from a mean of 28.3 degrees to 45.2 degrees.

We compared, under laboratory conditions, the resistance to cutting out of the AO dynamic hip screw and the Pugh sliding nail. The mean load at cut out, adjusted for bone strength, was 70% greater for the Pugh sliding nail. The reasons for this difference are discussed.

Nine patients have been reviewed at an average period of 22 years after a Watson-Jones tenodesis performed for chronic instability of the ankle. Only three patients had complete relief of symptoms. Two favourable early results deteriorated 7 and 10 years after operation. Radiographic examination revealed full correction of both anterior and lateral instability of the talus in only two cases. Talar tilt was controlled more successfully than increased anterior drawer movement. Long-standing instability was associated with the formation of marginal exostoses, the severity of which appeared proportional to the degree of instability.

One hundred patients with acute ruptures of the lateral ligaments of the ankle were randomly allocated either to conservative treatment in a plaster cast or to operative repair. With the aid of stress tenography, the extent of the injury was established. There were 30 patients with isolated anterior talofibular ruptures and 20 with additional calcaneofibular ligament ruptures in each treatment group. Operative repair was associated with a higher incidence of complications in the first weeks, and slightly delayed the patients' return to work. At an independent two-year review there was no evidence that operative repair offered improved symptomatic or functional benefit.

The majority of patients with chronic infantile and juvenile forms of spinal muscular atrophy survive to adult life. Forty-four patients have been reviewed at an average of 17 years after diagnosis. The subdivision of patients into four groups, based on the maximal physical function developed by the individual, correlates well with the onset and severity of secondary deformity of the limbs and spine. This information allows anticipation of the problems and plans for their treatment to be made from early childhood. After analysis of the orthotic and surgical treatment received by these patients, a specific programme of care is recommended for each of the functional groups.

The stress-tenogram is a radiological technique for the investigation of injuries to the lateral ligament of the ankle, and combines the information previously provided by inversion and anterior stress radiographs, and the peroneal tenogram. It is designed to differentiate between stable and unstable ankles, and between isolated ruptures of the anterior talofibular ligament and combined tears of the anterior talofibular and calcaneofibular ligaments. A high degree of diagnostic accuracy has been confirmed at operative repair in a group of thirty-two patients.

Three members of a family with a symmetrical distribution of multiple metaphysial lesions presented during childhood with pathological fractures and showed a tendency to spontaneous resolution after maturity. The histological and radiological features suggested multiple non-osteogenic fibromata of bone.
