Bower et al: Comparison of exposure of the feline radial diaphysis by the craniomedial and craniolateral surgical approaches for repair of antebrachial fractures
Veterinary Surgery 8, 2025

Comparison of exposure of the feline radial diaphysis by the craniomedial and craniolateral surgical approaches for repair of antebrachial fractures

🔍 Key Findings

  • Craniomedial and craniolateral approaches provided comparable exposure of the feline radial diaphysis (p > .05).
  • Mean exposed surface area was slightly greater with the craniolateral approach, both including and excluding the supinator muscle, but differences were not significant.
  • Elevation of the supinator muscle increased exposure for both approaches.
  • Cadaver weight and limb side did not significantly affect exposure area.
  • The craniolateral approach allows easier patient positioning in lateral recumbency without traction or an assistant.
  • Craniolateral access facilitates dual bone fixation (radius and ulna) through a single approach.
  • The craniomedial approach carries greater risk to median and radial nerves during muscle elevation.
  • Findings validate the craniolateral approach as a practical alternative for feline antebrachial fracture repair.

Multiple Choice Questions on this study

In Bower 2025 et al., on radial diaphyseal exposure, which practical advantage is associated with the craniolateral approach?

A. Greater need for traction
B. Easier lateral positioning without an assistant
C. Higher risk to median nerve
D. Limited access to the ulna
E. Reduced visualization of the radius

Answer: Easier lateral positioning without an assistant

Explanation: The craniolateral approach allows relaxed lateral recumbency without traction or assistance.
In Bower 2025 et al., on radial diaphyseal exposure, what was the effect of elevating the supinator muscle?

A. It reduced exposure
B. It had no effect
C. It increased exposure
D. It destabilized the ulna
E. It increased nerve injury risk

Answer: It increased exposure

Explanation: Elevation of the supinator increased the measured surface area in both approaches.
In Bower 2025 et al., on radial diaphyseal exposure, which risk is more associated with the craniomedial approach?

A. Staple line leakage
B. Ulnar instability
C. Damage to median and radial nerves
D. Inadequate bone exposure
E. Inability to plate the radius

Answer: Damage to median and radial nerves

Explanation: The craniomedial approach requires caution due to proximity of median and radial nerves during muscle elevation.
In Bower 2025 et al., on radial diaphyseal exposure, which statement best describes the comparison between craniomedial and craniolateral approaches?

A. Craniomedial provided significantly greater exposure
B. Craniolateral provided significantly greater exposure
C. Both approaches provided comparable exposure
D. Only craniomedial was suitable for cats
E. Only craniolateral allowed plate placement

Answer: Both approaches provided comparable exposure

Explanation: The study found no statistically significant difference in exposed surface area between approaches.
In Bower 2025 et al., on radial diaphyseal exposure, which fixation strategy is facilitated by the craniolateral approach?

A. External skeletal fixation only
B. Single bone fixation
C. Dual bone fixation of radius and ulna
D. Intramedullary pinning only
E. Avoidance of ulnar manipulation

Answer: Dual bone fixation of radius and ulna

Explanation: The craniolateral approach enables access to both radius and ulna through one incision.
