Revision hip arthroplasty

Abstract

From 1990 to 2000 238 revision hip joint replacements were performed at Joint Replacement Department of CITO. Both cement and cementless implants as well as in case of need allografts in the form of bone chips and spongeous bone were used. Technique peculiarities of revision operations for Sivash and «Compomed» implants replacement are described. The working time for «Com- pomed» implants was detected to be up to 5 у ears, for Gerchev implants up to 7 years and for Sivash implants 10 years and more. In revision replacement the following complications occurred: lethal outcome — 2 cases, acute myocardial infarction in early postoperative period — 1 case (recovery), deep suppuration — 1 case (implant was removed), thromboembolia of small branches of a. pulmonalis — 3 cases (recovery), paresis of fibular portion of n. ischiadicus — 5 cases (complete function restoration), dysbacteriosis during antibacterial therapy — 2 cases (recovery). Results of treatment were evaluated in 140 patients in the periods from 3 months to 10 years. In 139 cases complete or almost complete restoration of operated limb function was clinically noted. In 37 out of 139 patients signs of bone resorption around the cup and stem of implant were detected roentgeno- logically.
