Title: Distal cement mantle thickness with a triangular distal centralizer inserted into the stem tip in cemented total hip arthroplasty. Author: Kawate K, Ohmura T, Nakajima H, Takakura Y. Journal: J Arthroplasty; 2001 Dec; 16(8):998-1003. PubMed ID: 11740754. Abstract: Fifty-seven hips undergoing a primary cemented total hip arthroplasty with use of a triangular distal centralizer inserted into the stem tip were investigated, with a special focus on distal cement mantle thickness. The subjects were 43 women and 3 men. When evaluated on conventional anteroposterior and lateral radiographs, the relative incidence of thin cement mantles in zones 3 or 5 owing to the distal centralizer was 15.8% (9 hips). Unsatisfactory findings were that the distal centralizer and distal part of the stem shifted to the cortex in 7 hips and bent or failed at the inserted site in 2 hips. There is risk of generating a thin cement mantle with use of the triangular centralizer and its insertion into the stem tip.[Abstract] [Full Text] [Related] [New Search]
