Middle Term Results of Native Implant «ESI» Use in Primary Total Hip Ar­throplasty

Abstract

Middle term results of 886 primary total hip replacements using «ESI» implants (cementless fixation of components) have been analyzed. In 22 cases (2.48%) revision was required. When implants with «Chyrulen»-like high molecular polyethylene leaner and cobalt-chromium alloy head were used (718 operations) early aseptic loosening (excluding early dislocation, trauma­tic instability, etc.) developed in 1.11% of cases. Total number of unsatisfactory results did not exceed 5%. The causes for revision interventions have been considered in details.
