Vandekerckhove et al: Quantifying the Stress in Stress Radiographs to Determine Sufficient Laxity of the Coxofemoral Joint
Veterinary and Comparative Orthopedics and Traumatology 1, 2024

🔍 Key Findings Summary

• Used VMBDmD to quantify hip laxity under increasing force in cadaveric dogs (n=34).
• 90% of hips reached ≥90% of LImax at 95.32 N, defining this force as sufficient for subluxation.
• LImax was not significantly influenced by osteoarthritis, weight, sex, or limb side.
• Position of device (lever length) influenced rate of laxity acquisition, not final LImax.
• LI curves were repeatable across 5 sessions, indicating elastic—not plastic—deformation.
