Abstract

Objectives: The aim of this study was to investigate the gross
anatomical features of the ulna and radius bones on the posterolateral aspect
of the forearm in Black Bengal goat (Capra hircus) to determine the site for
ulnar nerve block.

Methods: 15 radius and ulna bones of Black Bengal goats from three
different age groups (Group A: 1–2 years; Group B: 2–3 years; Group C: >3
years) were studied. Measurements of the length between the olecranon
tuberosity and styloid process on the posterolateral aspect of radius and ulna
bones were made, and the mean midpoints on this line were determined.

Results: Ulna was always fused with the radius except on the
posterolateral interosseous spaces at the proximal and distal ends. The ulnar
nerve coursed posterior to the ulna, between the flexor carpi ulnaris and
ulnaris lateralis muscles, and remained superficial at the midpoint of ulna.
Mean lengths of the midpoint on the posterolateral aspect of the ulna (on the
line between the olecranon tuberosity to the styloid process) were 7.27±0.16,
7.67±0.34 and 8.29±0.73 cm in Groups A, B and C, respectively.

Conclusion: These anatomical findings indicate that these mean
midpoints are the most convenient sites for ulnar nerve block in these three
age groups of Black Bengal goats.
