Resistance to lateral luxation of two canine total elbow replacement systems under variable mechanical loads.

Objective: To measure the loads required to induce lateral luxation of the Iowa State University (ISU) elbow implant, a modified elbow implant, and the normal canine elbow with the ligaments and joint capsule removed.

Study Design: Mechanical testing on cadaveric specimens

Sample Population: Twelve thoracic limbs were harvested from adult, medium sized dogs that had been euthanatized for reasons unrelated to the study.

Methods: The torque needed for luxation was identified on potted cadaver elbows under variable axial load and compared to ISU implants and modified implants.

Mechanical testing of orthopedic suture material used for extra-articular stabilization of canine cruciate ligament-deficient stifles.

Objective: To determine (1) if braided, polyblend orthopedic suture materials are mechanically superior to monofilament nylon leader and (2) have mechanical properties similar to biomechanical properties of the canine cruciate ligament.

Sample Population: Different suture material types.

Methods: Mechanical testing was performed on 5 different orthopedic suture materials: 80# test Mason monofilament nylon leader (MNL), FiberTape (FT), FiberWire (FW), Xgen OrthoFiber (XOF), and LigaFiba (LF) using a servohydraulic materials-testing machine.

Evaluation of scintigraphy to assess incorporation of intercalary cortical bone grafts in sheep.

Objective: To evaluate scintigraphy, radiography, and histomorphometric analysis for assessing incorporation of intercalary bone grafts and to compare incorporation of cortical autografts and allografts by the recipient.

Animals: 12 skeletally mature sheep.

Procedures: A 5-cm tibial defect was filled with a cortical allograft (n = 6) or autograft (6) and stabilized with an interlocking nail.

Clinical, ultrasonographic, and laboratory findings associated with gallbladder disease and rupture in dogs: 45 cases (1997-2007).

Objective: To identify clinical, laboratory, and ultrasonographic characteristics associated with gallbladder disease and rupture in dogs.

Design: Retrospective case series.

Animals: 45 client-owned dogs.
