Abstract
The purpose of this study was to comparatively measure the bone-pin interface strength in two types of hydroxyapatite-coated pins that differed in shape, diameter, and implantation technique. Both pin types are commonly used for tibia fixation. Thirty bicylindrical 5/4-mm stainless-steel pins (Group A) and 30 tapered 6/5-mm stainless-steel pins (Group B) were implanted in the left tibiae of 10 adult sheep. A monolateral fixator was mounted on the pins after implantation. A 5-mm-long bone segment was removed from the tibial mid-diaphysis to ensure high load at the bone-pin interface. Pin insertion torque was 830 ± 446 N/mm in Group A and 3415 ± 743 N/mm in Group B (p
