We report 16 orthopaedic patients who had antibiotic-associated diarrhoea (pseudomembranous colitis) after operation. There was an association with the use of cephradine and with the prolongation of prophylaxis for more than three peri-operative doses. Five cases occurred as a cluster, suggesting that the causative agent, Clostridium difficile, may be infectious in some situations.
We report a case of a painful soft tissue swelling in the thoracolumbar region of the spine of a breakdancer, which caused serious diagnostic difficulty because of coexisting congenital absence of a transverse process of the first lumbar vertebra.

Eighty-two infants less than 1 year of age who presented with a diagnosis of congenital hip dysplasia have been reviewed. Forty-one infants had a diagnosis of congenital dislocation of the hip (CDH), of which 14 were bilateral cases. Forty-one infants had a diagnosis of acetabular dysplasia, of which none was bilateral. The incidence of breech malposition was higher in the CDH group (34%) than in the acetabular dysplasia group (15%). The metaphyseal edge angle, which accurately discriminates between these two groups, is described. There was evidence of abnormal radiographic development in those children with acetabular dysplasia who were not treated by abduction splintage.
