骨接合術に対する Acutrak screw (ACUMED) の使用経験

抄録

The purpose of this study was to evaluate the clinical results of internal fixation of orthopaedical surgery using Acutrak screw. Ten patients (11 cases) were treated between September 2000 and May 2001. Nine men (10 cases) and 1 woman were treated, and their age at surgery was 15 to 60 (mean 26.2) years old. The mean follow-up period was 3.8 (1.5 to 8) months. Problems encountered during this study were as follows: one guide pin broke and remained in the bone, two screw drivers broke, and the one of bipartita patella had delayed union. The Acutrak screw is a headless tapered, self-tapping and fully-threaded device designed to provide interfragmentary compression. Its variable pitch creates gradual compression with each turn. The Acutrak screw may have some of the advantages of the Herbert screw in being headless.
