Summary of quantitative mechanical parameters reported in preclinical reverse dynamization studies.

Consideration	Human orthopedics	Veterinary orthopedics (dog/cat)	Implication for reverse dynamization
Limb loading	Bipedal: weight-bearing impossible without crutches or total offloading	Quadrupedal: partial unloading possible without assistance; patient can use the other three limbs	Early flexible phase is better tolerated, but risk of sudden excessive loading is higher
Postoperative compliance	Moderate to high (patient understanding and cooperation)	Highly variable (entirely owner-dependent; confinement often difficult to enforce)	Progressive stiffness modulation may help accommodate variable postoperative loading conditions
Bone healing pattern	Primary (direct) healing common in many settings	Secondary (callus) healing predominant in routine veterinary practice	Reverse dynamization may be conceptually compatible with this predominant healing pathway
Monitoring of consolidation	Serial radiographs, CT, ultrasound elastography, implantable sensors	Radiographs under sedation/anesthesia; advanced imaging not routinely available in all practice settings	Need for simple, robust transition criteria based on fixed time points rather than complex parameters
Body weight range	Narrow (typical adult: 50–100 kg)	Very wide (2 kg to over 80 kg depending on breed)	Mechanical parameters may require adaptation across a broad range of patient sizes
