Case description: A 4-year-old female Staffordshire Bull Terrier (dog 1) and a 6-year-old male Yorkshire Terrier (dog 2) were evaluated because of left pelvic limb lameness.
Clinical findings: Both dogs had a partial rupture of the left cranial cruciate ligament associated with a unilateral excessive tibial plateau angle (51° in dog 1 and 41° in dog 2) secondary to a growth anomaly.
Objective: To determine how frequently routine follow-up radiographic findings would result in a change to the postoperative plan following tibial plateau-leveling osteotomy (TPLO) in dogs.
Study design: Retrospective study SAMPLE POPULATION: Short-term group: 100 cases; intermediate-term group: 50 cases.
Objective: The aim of this study was to clarify the histological effects of tibial plateau levelling osteotomy on cranial cruciate ligament degeneration induced by excessive tibial plateau angle.
Objective: To compare the strength of four constructs used to secure an osteotomy in a Center of Rotation Angulation (CORA)-Based Leveling Osteotomy (CBLO) in an ex vivo model.
Study design: Ex vivo study.
Sample population: Thirty-two canine tibiae from 17 skeletally mature cadavers weighing between 18 and 33.2 kg.
Surgical management of chondrosarcoma with hemipelvectomy is well described, but there have been no reports on extensive excision involving bilateral pubis and unilateral ischium.
This report describes a novel pelvectomy technique for the treatment of chondrosarcoma in a large-breed dog. A 12-year-old Labrador Retriever presented for tenesmus due to a large, intra-pelvic mass which was confirmed on computed tomography (CT). Surgery involved removal of the entire left ischium and both pubic bones with preservation of both hind limbs.
Objective: To report complications and prognostic factors in dogs undergoing proximal abducting ulnar osteotomy (PAUL). To evaluate the ability to predict complications on the basis of post-operative radiographic examination.
Study design: Retrospective cohort study.
Animals: Sixty-six dogs.
Case description: A 2-year-old 5.1-kg (11.2-lb) castrated male Siberian cat was examined because of a history of an abnormal right pelvic limb gait and a 4- to 5-month history of progressive constipation. Radiographs obtained by the referring veterinarian showed an osteoproductive and osteolytic bony lesion that involved the right ischium and filled the obturator foramen.
Case description: A 5-year-old 4.0-kg (8.8-lb) castrated male domestic shorthair cat was referred because of grade 4/5 left hind limb lameness and swelling in the region of the second metatarsal bone of that limb.
Clinical findings: Computed tomography revealed an expansile osteolytic lesion of the second metatarsal bone associated with a periosteal reaction on the third metatarsal bone. There was no evidence of metastases.
Objective: To assess the accuracy and efficiency of performing ventral FHO (vFHO) after measuring the ideal femoral head and neck ostectomy angle (iFHOA), with and without guidance of a K-wire. To compare the iFHOA to the previously accepted 45° angle to guide vFHOs.
Study design: Randomized, controlled, ex vivo study.
Animals: Ten mixed-breed canine cadavers.
Objective: To investigate the effect of an excessive tibial plateau angle (TPA) and change in compressive load on tensile forces experienced by the cranial cruciate, medial collateral, and lateral collateral ligaments (CCL, MCL, and LCL, respectively) of canine stifle joints.
Sample: 16 cadaveric stifle joints from 16 orthopedically normal Beagles.
