Ability of the Tightrope® and percutaneous lateral fabellar suture techniques to control cranial tibial translation.

Objective: To compare the ability of the Tightrope® (TR) cranial cruciate ligament (CCL) technique, percutaneous lateral fabella suture (pLFS) technique, and normal CCL to control cranial tibial translation (CTT).

Study Design: In vitro biomechanical study.

Sample Population: Cadaveric canine pelvic limbs (n = 18 pairs).

Biomechanical comparison of strategies to adjust axial stiffness of a hybrid fixator.

Objectives: To evaluate strategies for increasing the axial stiffness of a hybrid external bone fixator.

Materials And Methods: Type Ia hybrid fixators, consisting of a uniplanar linear component connected to a circular ring, were tested in displacement controlled loading in axial compression. The basic hybrid construct was modified to explore strategies considered to increase fixator stiffness including: decreasing ring diameter, increasing ring thickness, adding pins to the ring fixation, and adding struts between the ring and vertical post components of the device.

Evaluation of composite resin materials for maxillomandibular fixation in cats for treatment of jaw fractures and temporomandibular joint luxations.

Objective: To identify a method of composite application for maxillomandibular fixation (MMF) in cats that ensures the material will remain bonded during convalescence but be easy to remove with a low complication rate.

Study Design: Experimental study.

Sample Population: Feline cadavers (n=88).

Biomechanics of aggressive inline skating: landing and balancing on a grind rail.

Currently, only epidemiological injury data have been reported for the new extreme sport of aggressive inline skating, or trick skating. No studies have examined the biomechanics of this sport, which involves repetitive jumping and landing from railings, ramps, and ledges, often over 1 m in height. We present results of a pilot study that examined the effect of skater experience and lower extremity biomechanics on energy absorption ability, and observed balance strategies used during two basic tricks.

Evaluation of an osteoconductive resorbable calcium phosphate cement and polymethylmethacrylate for augmentation of orthopedic screws in the pelvis of canine cadavers.

Objective: To evaluate the effect of an osteoconductive resorbable calcium phosphate cement (CPC) on the holding power of bone screws in canine pelvises and to compare the effect with that for polymethylmethacrylate (PMMA).

Sample Population: 35 pelvises obtained from canine cadavers.

Procedure: Each pelvis was sectioned longitudinally.
