Grip force was measured in 55 consecutive patients with chronic tennis elbow. Grip force was markedly reduced at the pathological side, but there was also a striking reduction of the grip force at the pathological side when the grip force was measured with a straight elbow, compared with the standard position of 90 degrees flexion. This reduction was highly significant at the pathological side but not at the normal control side.
Posterior capsulectomy is a complete excision of the posterior tibiotalar and talocalcaneal capsule with a release of the distal tibiofibular connection. The operation is proposed for a resistant or relapsed clubfoot, where remaining equinus is the major problem. A follow-up of 29 operations showed that the average talocalcaneal angle became normal in the AP and lateral views. The best results were obtained with long postoperative cast immobilization, i.e. 6 months.
Four patients with congenital pseudarthrosis in neurofibromatosis were treated with percutaneous transosseous fixation according to the Ilizarov method. Three tibias were first treated unsuccessfully with a Sofield procedure. After application of the Ilizarov fixator, consolidation was obtained in two cases after 6 and 19 months, respectively. A fourth case consisted of a congenital pseudarthrosis of the ulna, primarily treated with the Ilizarov system, which showed advanced consolidation after 4 months.
The use of autograft versus allograft bone in scoliosis surgery is critically evaluated by a multivariate statistical analysis. Two groups of patients matched for age, angle of curve, and length of fusion, forming a consecutive series of posterior arthrodesis for idiopathic scoliosis, were evaluated. Group A consisted of 83 patients receiving autografts, and group B consisted of 99 patients receiving allografts. There was a significant reduction in operation time in the allograft group, and blood loss also decreased. After 1 year there was no significant difference in correction of the curve. Given the problems of discomfort at the donor site scar, we recommend the use of allograft bone in scoliosis surgery.

The records of 100 patients (116 hips) with Legg-Calvé-Perthes' (LCP) disease, with a minimum follow-up of 4 years and treated at the University Hospital, Pellenberg, were reviewed. Sex, Salter's, and Catterall's classifications and lateral subluxation were found to be important prognostic indices. Older children tended to do worse than younger children, but statistical significance could not be established. "Head at risk" factors other than lateral subluxation were found to be unimportant as prognostic indices. Salter's classification was found to be simple, accurate, and significant, and could be made quite early. In the future, this should be an important consideration when making decisions on the management of LCP.
