Two hundred and thirty-five patients with displaced Colles' fractures were followed to union, and 209 patients to six months, specifically searching for hand pathology. The incidence of carpal tunnel syndrome was seventeen per cent at three months and twelve per cent at six months. The patients with the syndrome were significantly older and their fractures showed significantly greater residual dorsal angulation. Sixteen patients developed Dupuytren's disease between three and six months, when the incidence was eleven per cent. These patients were significantly older and had average fractures and anatomical results. All cases were mild, with only two contractures. Twenty-one patients were reviewed at a mean of 20.7 months post-fracture, when no case had significantly progressed.

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. Function was assessed at three months and at six months. The anatomical result was not influenced by the method of immobilisation but was related to the efficacy of reduction. 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.

This paper presents the results of adding the antibiotic cefuroxime to CMW bone cement in a group of patients undergoing total hip or knee replacement, in which the levels of cefuroxime were assayed in the blood, wound drainage fluid, urine and surplus bone cement. It was found that very small amounts of cefuroxime, less than 5%, were recovered in the urine, serum and drainage fluid in the first week following operation, and since it is known that cefuroxime is not metabolised or excreted elsewhere in the body, it must follow that approximately 95% remains in the bone cement as a potential source of prophylaxis against infection.
