title: Diabetes as pro-infective risk factor in total hip replacement.
abstract: It is widely accepted that diabetic patients, above all poorly controlled ones, are more susceptible to infection. To verify whether diabetes might be considered a pro-infective risk factor in total hip replacement, 1,042 patients, who from 1969 to 1979 underwent an operation for arthropros thesis of the hip, were studied. The patients were subdivided into two groups according to whether they were diabetic or not. The diabetic patients, though well controlled by diet or by diet plus oral hypoglycemic agents, received insulin for at least two days before surgery. In the early post-operative phase they showed transient worsening of glycemic control rapidly corrected by increased insulin dosage. The patients of both groups were operated in low air exchange operating theaters, by the same staff and using standardized surgical techniques, and all received antibiotic coverage as preventive treatment against infections for a week after surgery. Infection and suppuration occurred in 11% of diabetic patients and only in 2% of non-diabetic patients (p less than 0.001); in these cases the prostheses were removed after unsuccessful antimicrobial treatment. Our study indicates that diabetes mellitus must be considered a proinfective risk factor in patients who undergo an operation for total hip replacement and suggests that a conservative approach is required in diabetic patients.
