Ex Vivo Biomechanical Comparison Of Four Center Of Rotation Angulation Based Leveling Osteotomy Fixation Methods, Melody E. Whitney
Ex Vivo Biomechanical Comparison Of Four Center Of Rotation Angulation Based Leveling Osteotomy Fixation Methods, Melody E. Whitney
Theses and Dissertations
Thirty-two canine tibiae with patellae and patellar tendons were harvested from 17 skeletally mature cadavers. Each tibia was randomly allocated to a construct group: plate and pin (Plate), plate with countersink compression screw (HCS), plate with tension band (TB), or plate with HCS and TB (HCSTB). Samples were loaded by distraction until failure. The stiffness, yield load, and ultimate load were compared between each fixation method. No difference in stiffness of the constructs was detected between groups. Yield load and ultimate load for the HCSTB group was greater than the TB group, the HCS group, and the Plate group. CBLO …
Ex Vivo Biomechanical Evaluation Of A Novel Screw For Tibial Plateau Leveling Osteotomy, William Seth Kettleman
Ex Vivo Biomechanical Evaluation Of A Novel Screw For Tibial Plateau Leveling Osteotomy, William Seth Kettleman
Theses and Dissertations
Twelve pairs of cadaveric pelvic limbs were harvested from skeletally mature dogs. Tibias were randomly assigned pairwise to two study groups: locking buttress screw fixation (LBS) and bone-screw-fastener fixation (BSF). A tibial plateau leveling osteotomy (TPLO) was performed. Each specimen was positioned in a servohydraulic testing machine to simulate physiological orientation and loading at the mid-point of the stance phase at the walk. Cyclic loading was performed for 30,000 cycles at 4Hz with a peak-load of 1000N. The cyclic test was then continued by stepwise increasing the peak-load at a rate of 75N per 500 cycles until failure of the …
Comparison Of Abdominal Computed Tomography To Ultrasound In The Diagnosis Of Canine Biliary Disease Manifesting As Acute Abdominal Signs, Shanna Christine Marroquin
Comparison Of Abdominal Computed Tomography To Ultrasound In The Diagnosis Of Canine Biliary Disease Manifesting As Acute Abdominal Signs, Shanna Christine Marroquin
Theses and Dissertations
Biliary diseases are uncommon, potentially fatal causes of acute abdomen in dogs. Little information is present comparing the performance of computed tomography (CT) to ultrasound in identifying canine biliary pathology. Thirty-five client-owned dogs presenting for acute abdomen signs received an abdominal ultrasound and contrast-enhanced abdominal CT. Two authors reviewed the randomized, anonymized CT and ultrasound studies. Twenty-eight dogs had biliary pathology and seven dogs serving as controls had no evidence of biliary disease. The final diagnoses of patients with biliary pathology included cholelithiasis, gallbladder mucoceles, cholangiohepatitis/cholangitis, extrahepatic biliary obstruction, gallbladder wall edema, gallbladder wall mass, and cystic mucosal hyperplasia. Computed …
