ABSTRACT

Radiographic Study of Bone and Cortex Diameters of Metacarpus and Metatarsus in
Sheep, Onl J Vet Res 12 (2):33-37, 2008. Bone cortex
diameter and Cortex/Diameter coefficient (C/D) are important factors in bone
radiographic studies and diagnosis of its normal and abnormal conditions.
Authors report diameters of metacarpus and metatarsus, cortex, thoracic and
pelvic limb of sheep. Twenty-five thoracic and 25 pelvic limbs of native mature
sheep were collected from slaughterhouse. Radiographs were taken in dorso-palmar metacarpal and dorso-plantar
metatarsal view. Bone and cortex diameters and cortex/diameter ratio were
measured in metacarpal and metatarsal diaphysis and proximal and distal
metaphysis. Mean Cortex/Diameter coefficient was 0.24±0.01 in metacarpus and
metatarsus diaphysis. There was no significant difference in cortical thickness
and C/D ratio between metacarpus and metatarsus. Correlation of cortex with
bone diameter was significant in both thoracic and pelvic limbs. The results of
present study could be used to detect abnormal diameters in these bones.
