Study Design: Retrospective observational multicenter study.

Sample Population: A total of 139 dogs (<12 months of age).

Objective: To investigate the effects of oblique proximal ulnar osteotomy (PUO) on the healing of humeral intracondylar fissure (HIF) in spaniel breed dogs.

Study Design: Clinical retrospective study.

Sample Population: A total of 51 elbows from 35 spaniel dogs.

Lower body weight and increasing age are significant risk factors for complications following bi-oblique proximal ulnar osteotomy in dogs.

Objective: To report and evaluate the risk factors for complications following bi-oblique proximal ulnar osteotomy (PUO) in dogs.

Animals: 82 client-owned dogs (93 limbs).

Methods: Clinical records of dogs treated with bi-oblique PUO over a 5-year period were reviewed.

Proximal Ulnar Osteotomy as a Treatment for Humeral Intracondylar Fissure in a Shetland Sheepdog.

A seven-month-old male Shetland Sheepdog was presented for assessment of thoracic limb lameness of 3 weeks duration. Orthopaedic examination revealed severe discomfort in elbow extension, bilaterally. CT-scan confirmed presence of a complete humeral intracondylar fissure (HIF), bilaterally, and arthroscopic examination of both elbows confirmed the presence of the cartilaginous lesion previously reported in dogs suffering from HIF.

The Effect of Femur Positioning on Measurement of Tibial Plateau Angle: An In Vitro Study.

Five canine cadaveric pelvic limbs with intact cranial cruciate ligaments were used to quantify the effect of variation in limb positioning on the radiographic measurement of the tibial plateau angle (TPA) with reference to the degree of femoral condyle superimposition. Intra-osseous pin placement and a custom jig design allowed the controlled three-dimensional manipulation of limbs. Medio-lateral digital radiographic projections were taken with perfect femoral hemicondylar superimposition to establish a "reference" TPA (difference in position = 0 mm), and subsequently in varying degrees of supination/pronation and abduction/adduction.

Humero-anconeal elbow incongruity in spaniel breed dogs with humeral intracondylar fissure: Arthroscopic findings.

Objective: To report arthroscopic findings in dogs with humeral intracondylar fissure (HIF) and compare these findings in joints of dogs not affected by HIF on preoperative CT images.

Study Design: Controlled clinical study.

Animals: Dogs with HIF (14 dogs, 21 elbows) and dogs without HIF (20 dogs, 31 elbows).

Complications after proximal abducting ulnar osteotomy and prognostic factors in 66 dogs.

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.

Risk of infection after double locking plate and screw fixation of tibial plateau leveling osteotomies in dogs weighing greater than 50 kilograms.

Objective: To compare surgical site infection (SSI) rates after double locking plate and screw fixation (DLP), standard locking plate and screw fixation (LP), and conventional nonlocking plate and screw fixation (NLP) in dogs weighing >50 kg undergoing tibial plateau leveling osteotomy (TPLO).

Study Design: Retrospective study (January 2003-October 2017).

Animals: Two hundred seventy-five dogs weighing >50 kg with cranial cruciate ligament disease treated with TPLO.

Use of Synthetic Osteochondral Implants to Treat Bilateral Shoulder Osteochondritis Dissecans in a Dog.

Case Description:  An 8-month-old American Bulldog was presented for assessment of bilateral thoracic limb lameness. Computed tomographic imaging revealed large, deep osteochondritis dissecans lesions in both humeral heads.

Treatment And Outcome:  The osteochondritis dissecans lesions were debrided and the exposed subchondral defects were prepared to receive synthetic grafts.

Long-term complications following tibial plateau levelling osteotomy in small dogs with tibial plateau angles > 30°.

Tibial plateau levelling osteotomy (TPLO) is commonly performed for surgical management of cranial cruciate ligament (CCL) disease. It has been suggested that small dogs may have steeper tibial plateau angles (TPAs) than large dogs, which has been associated with increased complication rates after TPLO. A retrospective study was performed to assess the rate and nature of long-term complications following TPLO in small dogs with TPAs>30°.

Surgical management of pivot-shift phenomenon in a dog.

CASE DESCRIPTION A 6.8-year-old neutered male Labrador Retriever-Poodle mix was evaluated because of continued left pelvic limb lameness unresponsive to conservative management 1 year after undergoing tibial plateau leveling osteotomy (TPLO). CLINICAL FINDINGS A jerking lateral movement of the left stifle joint was detected during walking.

Use of a subdermal plexus flap to reconstruct an upper eyelid following radical tumor resection in a cat.

CASE DESCRIPTION A 15-year-old neutered male domestic shorthair cat was examined for treatment of a recurrent neoplastic mass in the left upper eyelid that had been excised 6 months earlier by the referring veterinarian. CLINICAL FINDINGS An apparently nonpainful firm cutaneous mass (approx 2 × 2 mm) was located on the lateral third of the left upper eyelid near the scar from the previous surgical excision. TREATMENT AND OUTCOME Approximately one-third of the left upper lip was used as a subdermal plexus (lip-to-lid) flap to cover the defect created by en bloc excision of the eyelid mass.

Evaluation of an Axial Pattern Flap Based on the Cranial Cutaneous Branch of the Saphenous Artery: A Cadaveric Perfusion Study.

Objectives: To confirm the anatomic location of the cranial cutaneous branch of the saphenous artery (CCSA), delineate the angiosome of the CCSA, and provide guidelines for clinical use of an axial pattern flap based on the CCSA.

Study Design: Anatomic study.

Animals: Greyhound cadavers (n=10).

Locking plate and screw fixation after tibial plateau leveling osteotomy reduces postoperative infection rate in dogs over 50 kg.

Objective: To assess the influence of locking plate and screw implants on postoperative infection rate in dogs >50 kg undergoing tibial plateau leveling osteotomy (TPLO).

Study Design: Retrospective case series.

Animals: Dogs >50 kg (n = 208) that had TPLO.
