Cefazolin concentration in surgically created wounds treated with negative pressure wound therapy compared to surgically created wounds treated with nonadherent wound dressings.

Objective: To compare cefazolin concentrations in biopsied tissue samples collected from surgically created wounds treated with negative pressure wound therapy to those collected from surgically created wounds treated with nonadherent dressings.

Study Design: Prospective, controlled, experimental study.

Animals: Adult female spayed Beagles (n = 12).

Biomechanical testing of locking and nonlocking plates in the canine scapula.

Locking plates have been shown to offer improved fixation in fractures involving either osteoporotic bone or bone with lesser screw pullout strength, such as thin and flat bones. Fractures of the scapular body are one type of fracture where the screw pullout strength using conventional plate fixation may not be sufficient to overcome physiologic forces. The purpose of this study was to compare the pullout strengths of locking plates to conventional nonlocking plates in the canine scapula.

Perpendicular pull-out force of locking versus non-locking plates in thin cortical bone using a canine mandibular ramus model.

Objective: To compare the holding strength of a conventional plate-screw construct with a locking plate-screw construct in the thin cortical bone of the canine mandibular ramus.

Study Design: Mechanical study.

Animals: Paired cadaveric canine mandibles (n = 10 pairs).
