Review finds no direct evidence on feline tibial fixation choice

A new Knowledge Summary in Veterinary Evidence finds there’s still no direct comparative evidence to answer a practical orthopedic question many clinicians face: in cats with closed diaphyseal tibial fractures, does internal fixation lead to fewer postoperative complications than external fixation? Authors Stephen Keith John and Jake Chitty reported that their literature search found no studies directly comparing the two approaches for this specific fracture type, leaving the strength of evidence at zero. The paper was published April 28, 2026. (veterinaryevidence.org)

Why it matters: For veterinary teams, the takeaway isn’t that the two methods are equivalent, but that case selection still has to do the heavy lifting. The review notes that both internal fixation and external skeletal fixation are established options in cats, but the absence of direct feline data means surgeons must lean on fracture configuration, available equipment, soft-tissue considerations, and their own experience. That gap matters because tibial fractures in cats are relatively common, diaphyseal injuries make up a large share of them, and tibial repair is already associated with risks including delayed union, non-union, implant failure, and osteomyelitis.

What to watch: The next meaningful step would be a retrospective or prospective feline study that directly compares complication rates for internal fixation versus external fixation in closed diaphyseal tibial fractures. (veterinaryevidence.org)
