ANTIBIOTICS IN ACUTE OSTEOMYELITIS IN CHILDRENN. J. Blockey 1; and T. A. McAllister 1
1 Royal Hospital for Sick Children, Glasgow, Scotland
1. Continued follow-up of the 113 children with acute osteomyelitis previously reported and a study of a further thirty-eight proven cases has not changed our opinion that the correct management is rest and effective antibiotics. Operation should be undertaken only if pus is detectable clinically. 2. Bacteriological evidence shows that the flora causing this disease are less sensitive to benzylpenicillin than ten years ago and that a proportion are also likely to become resistant to methicillin and cloxacillin. 3. The most effective antibiotic combination used was fusidic acid and erythromycin. This lowered the failure rate to 10·5 per cent in thirty-eight proven cases. Two of the four failures were in haemophilus infections. No staphylococcal infection of a long bone became chronic, and all lesions were healed within three months of onset. 4. The duration of treatment (twenty-one days) and the method of splintage (removable plaster slabs) remained the same as in the previous series. 5. Careful watch must be kept on the incidence of haemophilus infections. If it rises, increasing the erythromycin or adding ampicillin may be necessary. 6. Use of the newer aqueous suspension of fusidic acid may lower the incidence of troublesome vomiting (12 per cent in this series). 7. Only 7 per cent of staphylococcus aureus infections in this hospital, and 17 per cent of such infections in our thirty-eight cases were sensitive to benzylpenicillin. It is thought that this drug has outlived its usefulness in osteomyelitis. 8. It is recommended that, on diagnosis, fusidic acid aqueous suspension 5 millilitres should be given three times a day to children aged one to five, and 10 millilitres twice a day for children aged six to twelve, with erythromycin stearate 30 milligrams per kilogram of body weight each day in divided doses.
