Nineteen patients suffering from subacute (latent) or recently arrested sepsis of the hip joint were treated by massive doses of antibiotics and total prosthetic reconstruction. A minimum of two years' follow-up is recorded. Recurrence of infection caused failure in two patients, possibly because of inadequate antibiotic treatment. Results were satisfactory in the other seventeen patients, and infection did not recur. The ultimate symptomatic and functional results of reconstruction in the patients with satisfactory results were classified as excellent in nine patients, good in six, and fair in two. One patient with a good result required a revision because of loosening of the prosthesis. All results were considered superior to those from simple resection of the hip (the Girdlestone procedure).
