Primary Hip Replacement with Cementless «ESI» Implants

Abstract


Comparative analysis of the outcomes of cementless implantation of total metal-polymeric structurized hip implants «ESI» of various generations was performed. Results of 1095 implantations (876 patients) performed during the period from 1995 to 2008 were evaluated. Follow-up was from 6 months to 12 years (mean term 7.3 years). Comparison of the results was performed between four groups differed by the modification of applied «ESI» implant. Characteristics for every of four «ESI» implant generations were presented. In the first group (1st generation of implants) assessment of treatment outcomes by Harris showed no excellent and good results, satisfactory results made up 4%, poor results - 96%. In the second group (2nd generation) excellent results were achieved in 3% of cases, good one in 18%, satisfactory - in 36% and poor result was noted in 43% of cases. In the third group (3rd generation) the results made up 27, 63, 8 and 2%, respectively. In group four (4th generation) excellent results made up 32%, good - 64%, satisfactory - 4% with no poor results observed.
