Comparative Study Clinical TrialFunctional cast-bracing for Colles' fractures. A comparison between cast-bracing and conventional plaster casts.
The use of Orthoplast cast-bracing to allow early hand function in the treatment of displaced Colles' fractures was investigated in 243 patients. They were randomly allocated into three groups: in the first a conventional Colles' type plaster was used; in the second an above-elbow cast-brace with the forearm in supination; and in the third a below-elbow cast-brace. Radiographic measurements were made at each stage of treatment, and the final anatomical result was scored using Sarmiento's (1975) criteria. ⋯ Loss of position in the braces was no greater than in plaster. The functional result at three months also was uninfluenced by the method of immobilisation; it was, however, related to the severity of the initial displacement, and (to a lesser degree) to the anatomical result, an effect which was lost at six months. Early hand function and the supinated position advocated by Sarmiento were found to confer no anatomical or functional advantage; we could see no reason to change from the use of conventional plaster casts in the treatment of uncomplicated Colles' fractures.

Case ReportsIntra-operative awakening to monitor spinal cord function during scoliosis surgery. Description of the technique and report of four cases.
We used a modification of the wake-up test to monitor spinal cord function in 102 consecutive scoliotic patients undergoing Harrington instrumentation. Four patients were found to have a neural deficit when they were awakened during the operation. ⋯ Using our method, we have encountered no problem in performing the wake-up test, although attention is drawn to the difficulty in repeating the test if the patient is re-anaesthetised with diazepam. There were no false negative results in this series.

Previous reports have suggested that the blood supply derived from the anterior tibial artery is absent or markedly diminished in 85% of severe, untreated club feet. To investigate these claims, we used a Doppler technique to study the arterial pulses in 40 children with 63 club feet. ⋯ These results confirm that the incidence of pulselessness increases with the severity and duration of deformity, but not to the extent previously suggested by angiographic studies. The significance of these findings is discussed.
