We performed a randomised double-blind controlled study in patients undergoing elective knee arthroscopy to assess the effect of intra-articular morphine on postoperative pain relief. Patients in the study group (n = 10) received 5 mg of morphine in a 25 ml dilution intra-articularly while those in the control group (n = 10) received 25 ml of saline. Postoperative pain was assessed at intervals by a visual analogue scale and the requirement for supplementary analgesia was recorded. Those in the study group had significantly lower pain scores and required less systemic analgesics than those in the control group. Plasma profiles for morphine and its metabolites were assayed and showed that they were too low to produce effective analgesia. Evidence suggests that analgesia was mediated by local action within the joint.

The transiliac method of leg lengthening uses a modification of Salter's innominate osteotomy. The bone graft increases the length of the hemipelvis distal to the sacro-iliac joint. Leg-length inequality in 23 patients was treated by this method with an average gain in length of 2.8 cm (2.0 to 3.5). Apart from one residual femoral nerve palsy there were no notable complications. The facility to redirect the acetabulum allowed by the technique, may be useful in cases of potential hip instability or acetabular dysplasia.

A Salter innominate osteotomy is used to treat acetabular dysplasia, but reports of its effects on the position of the femoral head are few and conflicting. Lateral shift would increase the resultant forces acting on the joint and be detrimental. We studied 15 Salter innominate osteotomies and demonstrated that a correctly performed osteotomy does not significantly alter the distance from the centre of the femoral head to the midline of the body. Stereophotogrammetry was used in three patients to delineate the axis of rotation of the distal acetabular fragment and determine the locus of movement of the centre of the femoral head about it. Our results explain why the Salter osteotomy does not lateralise the femoral head.

We reviewed 26 fractures involving the distal physis of the tibia to identify the patterns of formation and displacement of the subsequent growth disturbance lines. Twenty-one patients showed a regular "normal" pattern of line and healed with no deformity. Three patients had medical physeal arrest revealed by abnormal lines. Two other cases had a minor central physeal arrest without subsequent deformity. The pattern and character of the growth disturbance line can provide an early warning of potential deformity.

Hip rotation in extension and flexion was studied in 23 patients with idiopathic intoeing gait. In extension all the hips had markedly increased medial rotation and limited lateral rotation, fulfilling the criteria of excessive femoral anteversion. In flexion, however, rotation varied widely; in one group of patients medial rotation remained greater than lateral, but in the second group lateral rotation was equal to or greater than medial. CT scans showed that the hips in the first group were significantly more anteverted than those in the second. Clearly measurement of hip rotation in extension alone does not provide a dependable indication of femoral anteversion in children with intoeing gait; rotation in flexion also needs to be measured.

Seventy-seven children admitted with a provisional diagnosis of acute osteomyelitis over a three year period have been reviewed. Acute haematogenous osteomyelitis was confirmed in 45 of these patients whose ages varied from three days to 14 years with a mean of 6.2 years. All patients were treated with intravenous fusidic acid and cloxacillin with splintage for three weeks followed by oral antibiotics for a further period of six weeks. Only seven patients required operation. One patient had recurrence of infection; all other patients were cured with no evidence of chronic osteomyelitis. It is suggested that surgical drainage of acute haematogenous osteomyelitis is seldom needed and that high intravenous doses of antibiotics in combination with splintage are adequate treatment in most cases.
