Screw loosening six weeks after triple pelvic osteotomy: Comparison of pre-tapped with self-tapping 3.5 mm cortical screws.

摘要

A retrospective study of 62 dogs that underwent unilateral triple pelvic osteotomy with a Slocum triple pelvic osteotomy plate and Synthes 3.5 mm cortical screws. We compared the probability of screw loosening after six weeks in dogs in which pre-tapped screws were used (30 dogs), with dogs in which self-tapping screws were used (32 dogs). Screw loosening was significantly less prevalent with self-tapping screws than pre-tapped screws.
