Q

Watrous, VCOT, 2018:
1.5mm LCP vs 1.5mm straight plate vs 2.0mm straight plate
Which plate had the highest stiffness?
1.5mm LCP vs 1.5mm straight plate?

A

Watrous, VCOT, 2018:
The 2.0mm straight plate had the highest stiffness
The larger hole-to-hole distance of the 1.5mm LCP compared to the 1.5mm straight plate could limit the number of screws that can be placed in a small fragment, and the torsional stiffness of the 1.5mm LCP was not statistically different from that of the 1.5mm straight plate

Q

Ree, Vet Surg, 2018:
Autologous greater omentum free graft vs autogenous cancellous bone graft
Minor complication rate with omental graft vs bone graft?
Major complication rate with omental graft vs bone graft?
Effects of omental graft on ground reaction forces?
What % developed osteopenia with omental graft vs bone graft?
Adverse effects of the omental graft?

A

Ree, Vet Surg, 2018:
Minor complications: 64% for omental graft vs 17% for bone graft
Major complications: 0% for omental graft vs 8% for bone graft
The omental graft group had improved ground reaction forces (increased peak vertical force and vertical impulse) and earlier return to weight-bearing
Osteopenia developed in 36% of the omental graft group vs 58% of the bone graft group
Adverse effects of the omental graft were limb swelling and erythema in 64% of the dogs due to reactive omentum becoming enlarged and edematous

Q

What did Ree et al VetSurg 2018 conclude about momentum free graft vs bone graft from R/U fractures in mini breeds?

A

Omental graft - faster bone union, greater peak vertical force, more vessels, no major complications
Bone graft - increased cortical bone density

17

Long term functional outcomes excellent regardless of technique used

complications more common with pin and tension band

Avoid pin and tension band in comminuted fractures
