Analysis of 2.0 and 3.5 mm Cortical Bone Screw Dimensions.

ABSTRACT: Investigation and quality assessment of veterinary orthopaedic implants are seldom undertaken, despite their critical role in clinical outcomes. Dimensional accuracy is particularly important for screw-bone interface stability. This study aimed to evaluate the dimensional consistency of commonly used veterinary bone screws. Sixty unused stainless steel cortical screws (2.0 mm and 3.5 mm) were randomly selected from larger batches. Each screw was examined microscopically, and six measurements were obtained from three distinct regions along the screw length. Major (outer) diameter and pitch were recorded and compared against standard tolerance ranges. For 2.0 mm screws, 28.6% of major diameter and 75% of pitch measurements were outside the tolerance range. For 3.5 mm screws, only 56% (major
