Objectives: To describe a novel humeral fixation device, the insertion technique, healing of humeral osteotomies, and clinical outcomes in a caprine model over a six month period. Methods: Fourteen mature female Boer/Nubian cross goats with a mean body weight of 50.7 kg were implanted with a proprietary segmented interlocking nail (SILN) in both humeri. Each goat had one humerus randomly selected for mid-diaphyseal osteotomy. Results: Immediately after surgery all but one goat was able to stand, although none of the goats were weight bearing on the osteotomy limb.

Objective: To report repair of a coxofemoral joint luxation in an Alpaca using a toggle-pin technique.

Study Design: Case report.

Animals: An 11-month intact male Alpaca with luxation of the right coxofemoral joint.

Methods: The Alpaca was anesthetized and an open repair and reduction of the luxation was performed using a toggle-pin technique.

In this report, a case of cranial cruciate ligament (CrCL) rupture treated by tibial plateau levelling osteotomy (TPLO), in a 36-month-old male breeding alpaca, is described. The alpaca was presented with the complaint of acute onset of right pelvic limb lameness. The findings of our clinical and radiographic examinations were consistent with CrCL insufficiency of the right stifle joint. The right tibial plateau angle measured prior to surgery was 19°. A TPLO was performed and this eliminated cranial tibial thrust.

Objective—To report management of a chronic slipped capital femoral epiphysis (SCFE) in an alpaca using cementless total hip replacement (THR).

Study Design—Case report.

Animal—An 18-month-old, 47 kg alpaca male.

Methods—Cementless THR was performed in an alpaca with a chronic, right SCFE, and secondary osteoarthritis. Force plate gait analysis was performed before and 8 weeks after surgery. Outcome was determined through clinical evaluation, radiography, and force plate gait analysis.

Objective—To report surgical treatment of traumatic lateral patellar luxation using trochlear block recession in an alpaca.

Study Design—Clinical case report.

Animals—Five-year-old female alpaca.

Methods—Grade IV/IV lateral, left patella luxation and mild femoropatellar joint effusion was identified by palpation and visual assessment, and confirmed by ultrasonography and radiographs. Trochlear block recession combined with lateral retinacular release and medial imbrication to restore patella function.

Case Description—A 10-year-old Longhorn cow pregnant with a valuable fetus was evaluated because of progressive inspiratory dyspnea of 6 weeks' duration.

Clinical Findings—Physical examination findings were consistent with upper respiratory tract obstruction. A large pedunculated soft tissue mass was evident in the mid-dorsal aspect of the pharynx during palpation and endoscopic examination. Results of microscopic examination of transendoscopic fine-needle aspirates and a biopsy specimen were suggestive of a bacterial granuloma.

Objective—To report use of a cementless total hip prosthesis in an alpaca.

Study Design—Case report.

Animals—Alpaca (n=1) with chronic craniodorsal coxofemoral luxation.

Methods—A 2.5-year-old Suri alpaca, 3 months pregnant, was admitted for evaluation of acute onset severe left hind limb lameness (grade 4/5) of 6 weeks duration. After diagnosis of craniodorsal luxation of the left femoral head, total hip replacement (THR) using a cementless implant was performed because of the poor prognosis for reduction of a chronic luxation.
