The effect of a smoke-evacuation unit on ultrafine particle concentrations in the operating room during approach to the proximal tibia for tibial plateau-leveling osteotomy surgery in dogs.

Objective: To evaluate the effectiveness of a smoke-evacuation unit on reducing ultrafine particle concentration in the operating room (OR) during the approach to the proximal tibia for tibial plateau-leveling osteotomy (TPLO).

Study Design: Prospective, randomized, controlled clinical trial.

Sample Population: Twenty-nine client-owned dogs undergoing unilateral TPLO at a single institution were assigned to either smoke-evacuator groups (SE; n = 15) or non-smoke-evacuator groups (NSE; n = 14).

Greater trochanter morphology and association with patient demographics, surgical factors, and post-operative stem position: a retrospective assessment of 150 cementless THRs in 135 dogs.

Background: Total hip replacement (THR) in the gold standard surgical treatment for the canine hip. While it has been shown that greater trochanter morphology affects post-operative cementless stem position in humans, trochanter morphology and the effect on cementless stem position has not been extensively evaluated in dogs. The objective of this study was to classify greater trochanter morphology and identify potential associations between trochanter morphology and patient demographics, femoral canal geometry, surgical time, technique modifications, and post-operative stem position in client-owned dogs undergoing cementless THR.
