Payne et al: Computed Tomography Topographical Analysis of Incomplete Humeral Intracondylar Fissures in English Springer Spaniel Dogs
Veterinary and Comparative Orthopedics and Traumatology 2, 2024

🔍 Key Findings Summary

• HIF typically originates 57° caudal to the supratrochlear foramen and propagates cranially in a segmental pattern.
• %HIF correlated significantly with both fissure depth and length:
  • %DHIF increased linearly (r = 0.989, p < 0.001)
  • %LHIF followed a sigmoidal relationship with %HIF (p < 0.001)
• Higher %HIF was significantly associated with:
  • Clinical lameness (p = 0.004)
  • Distal shift in the fissure center (CHIF)
• Implant complications in 5/17 elbows treated with transcondylar screws
• Isthmus diameter increased with weight (p = 0.002), relevant for screw sizing
