Abstract This report aims to describe implant characteristics and procedure for implantation, and comment on and report the clinical outcomes in small dogs and cats using the new Zurich mini cementless total hip system. This study involved 8 cats and 42 dogs, with 3 cats and 6 dogs having bilateral total hip arthroplasties (THA). The mean body weight for cats was 6.5 kg, and the mean body weight for dogs was 9.2 kg. In the group of THAs in cats, capital physeal fracture was the reason for performing a THA in six cases (60%), hip dysplasia was the underlying reason in four cases (30%) and hip luxation in one case (10%). Among the 48 THAs in dogs, hip dysplasia was the underlying cause for performing THA in 27 cases (56%), avascular necrosis of the femoral head in 12 cases (25%), traumatic luxation with underlying hip dysplasia in 4 cases (8.5%), capital physeal fracture in 4 cases (8.5%), and traumatic femoral head fracture in 1 adult dog (2%). Seven postoperative complications were encountered, and all were solved without the need for explanting the prosthesis, except in one case because of the owner's decision. In conclusion, the Zurich mini cementless total hip system performed well in this study, with most dogs and cats having an excellent outcome and no patient being too small for the available implant sizes.

Congenital humeroradial subluxation was diagnosed by clinical examination and radiography in a 16-week-old female dog that presented for left forelimb lameness. This was treated surgically by open reduction followed by placement of an ultra-high molecular weight polyethylene suture from the craniolateral aspect of the proximal radius to the caudomedial aspect of the ulna, secured with a toggle and suture button. Postoperative findings were consistent with clinical improvement and radiographs were compatible with resolution of elbow subluxation. To our knowledge, this is the first case report of congenital humeroradial subluxation to be managed with an ultra-high molecular weight polyethylene suture toggle.

A 2-year-old male neutered crossbreed was presented with a 7-month history of left pelvic limb lameness. Following a diagnosis of bilateral hip dysplasia, staged hybrid total hip replacements (THR) were performed 16 months apart. An ipsilateral grade II lateral patellar luxation (LPL) developed within 24 hours after each THR. Both LPLs were successfully treated by block recession sulcoplasty. Subjective gait analysis showed an abnormal pelvic limb gait following each THR. Clinical examination detected a grade II LPL on each operated limb. Computed tomography of both pelvic limbs revealed mild trochlear sulcus hypoplasia but no other skeletal abnormalities. Trochlear block recession sulcoplasty was performed 10 and 4 weeks respectively after THR. Long-term follow-up 12 months after the last surgery found minimal (0–1/10) lameness, no pain on clinical examination in both PLs and an overall low client-based metrology instrument mobility score of 2 (Liverpool Osteoarthritis in Dogs). This case report documents that in predisposed dogs, with hypoplastic trochlear ridges, LPL can occur secondary to THR and can be successfully managed by standard techniques to address the luxation. Furthermore, despite anecdotal verbal reports of medial patellar luxation occurring secondary to THR in dogs, this is the first published report of the management of any patellar luxation subsequent to THR.

Objective The aim of this study was to report on complications and outcomes with repair of ruptured canine patellar tendons using primary tenorrhaphy coupled with patellar tendon allograft transplantation and use of a transarticular external skeletal fixator. Materials and Methods This report includes three dogs with acutely ruptured patellar tendons, all of whom had surgical repair using a patellar tendon allograft. Dogs were assessed postoperatively by physical examination, owner input, and/or video review. Functional outcomes were classified as full, acceptable, or unacceptable based on previously established criteria. Results Follow-up time was between 24 and 46 weeks. Two dogs obtained full function and one dog reached acceptable function. The acrylic connecting bars of the external fixator fractured and needed to be replaced in one dog. There were no other problems or complications. There was no evidence of rejection of any allograft. Clinical Significance Primary tenorrhaphy supported by patellar tendon allograft transplantation and transarticular skeletal fixation appears to be a viable option without evidence of patellar tendon allograft rejection and acceptable or full recovery in the three dogs of this report.

The aim of this study was to report the successful outcome of a tibiotarsal fracture in a turkey vulture managed with a supracutaneous plating technique. This is a case report study design. A juvenile male turkey vulture (Cathartes aura) was presented unable to walk. Physical exam revealed instability in the left tibiotarsus. Radiographs confirmed a comminuted mid-diaphyseal fracture of the left tibiotarsus. The turkey vulture underwent fracture stabilization using fluoroscopic guidance with a 12-hole 2.4-mm locking compression plate (LCP) placed in a supracutaneous fashion with locking screws proximally and distally. The turkey vulture was ambulatory immediately following surgery, and lameness had resolved by day three. Four weeks postoperatively, radiographs demonstrated loss of cortical bone density, and the construct was dynamized. At 6 weeks postoperatively, radiographs revealed a bridging callus, and all implants were removed. Following an additional 2 weeks of cage rest, recheck radiographs confirmed continued fracture healing and increased cortical density. At week nine, the turkey vulture was transitioned to a pre-release flight cage where the vulture was noted to set flight, land, grasp, walk, and perch normally. The turkey vulture was released 12 weeks postoperatively. This case report documents the successful functional outcome of a closed, comminuted mid-diaphyseal fracture of the tibiotarsus in a minimally invasive manner utilizing a supracutaneous plating technique. Based on a literature search, this is the first report utilizing supracutaneous plating for a tibiotarsal fracture in a turkey vulture.

Objective The aim of this study was to compare effects with conventional (needle and electroacupuncture, NAP) and shockwave stimulation of acupuncture points (SAP) on chronic multilimb lameness in horses. Study Design Randomized crossover block design; ten mature Standardbred mares with multilimb lameness (< 4/10) underwent 3-weekly point stimulations (NAP/SAP) selected on the basis of their uniform applicability. Groups were reversed following a washout period (9 weeks). Lameness at the trot was video recorded and quantified objectively using an inertial sensor-based system during a 4-week pre- and post-treatment period. Blinded expert review of recordings resulted in subjective qualitative (better, same, or worse) and quantitative outcome measures (0–10 lameness grade). Mixed effect repeated measures analyses were performed on objective quantitative gait parameters specific to fore (Vector sum [VSHead]) and hindlimb lameness (average differences in minimum [DIFFMINPelvis] and maximum pelvic height [DIFFMAXPelvis]) Qualitative data were assessed in non-parametric tests. Results SAP had no effect on forelimb but improved hindlimb lameness (DIFFMINPelvis; p < 0.001). NAP was associated with deterioration of forelimb lameness (VSHead, p < 0.001) and had no effect on hindlimb lameness. VSHead data differed between modalities when accounting for the time of observation (interaction effect; p = 0.002). For other quantitative gait parameters, a difference between modalities was not observed. SAP was associated with greater animal comfort post-treatment compared with pre-treatment assessments (p = 0.036). Typically, improvement occurred by one and deterioration by two lameness grades. Conclusion SAP and NAP were not associated with the same treatment outcome. SAP slightly improved but did not alleviate all lameness. Given the non-invasive nature of SAP, this method may have potential in the management of chronic multilimb lameness.
目的比较传统针刺(针刺和电针，NAP)和穴位冲击波刺激(SAP)治疗马慢性多肢跛的疗效。研究设计随机交叉区设计;选取10匹多肢跛行(< 4/10)的成熟标准种母马，根据其统一适用性进行3周点刺激(NAP/SAP)。各组在洗脱期(9周)后被逆转。在治疗前和治疗后的4周时间里，使用基于惯性传感器的系统对小跑时的跛行进行视频记录和客观量化。对记录进行盲法专家评审，得出主观定性(更好、相同或更差)和定量结果测量(0-10跛行等级)。对前肢(Vector sum [VSHead])和后肢跛行(最小[diffmin骨盆]和最大骨盆高度[diffmax骨盆]的平均差异)的客观定量步态参数进行混合效应重复测量分析。定性数据在非参数检验中进行评估。结果SAP对前肢无明显影响，但可改善后肢跛行(diffmin骨盆;p < 0.001)。NAP与前肢跛行恶化相关(VSHead, p < 0.001)，对后肢跛行无影响。考虑到观察时间(相互作用效应;p = 0.002)。对于其他定量步态参数，没有观察到不同模式之间的差异。与治疗前评估相比，SAP与治疗后更大的动物舒适度相关(p = 0.036)。典型地，一个跛行等级发生改善，两个跛行等级发生恶化。结论SAP与NAP治疗效果不一致。SAP略有改善，但并没有减轻所有的跛行。鉴于SAP的非侵入性，该方法可能在治疗慢性多肢跛行方面具有潜力。

This case report describes the case of a 4-year-old toy poodle who underwent reconstruction using an autologous caudal vertebral graft for nonunion and osteomyelitis of a left radioulnar fracture. Radial reconstruction was performed 14 days after the removal of existing implants. Three autologous caudal vertebrae mounted onto a titanium T-plate were used to fill the radial bone defect. Rehabilitation was initiated 3 weeks after surgery. By the fifth week after surgery, the dog showed weight bearing on the affected limb. One year after the reconstruction surgery, revision surgery for replacing all implants was performed due to increased radiolucency of the graft. The dog remained clinically stable, and radiographic bone union was complete 3 years and 2 months after the first surgery. An autologous caudal vertebral graft was successfully used for the treatment of a large radial defect in a dog suffering from atrophic nonunion. Clinical improvement was prompt, and the long-term functional outcome was satisfactory.

Four French bulldogs were presented with a history of cervical pain and/or signs of myelopathy and were diagnosed with an acute cervical intervertebral disc extrusion (IVDE), associated with epidural haemorrhage (EH). The lesion was classified as IVDE with EH by a board-certified radiologist based on contrast-enhanced computed tomography images. All dogs were treated with two adjacent ventral slots that confirmed diagnosis. The decompression was assessed by measurement of the amount of residual material on computed tomography studies, and the outcome was evaluated by clinical recheck. All dogs recovered uneventfully after the surgery. This case series describes the first detailed report of extensive cervical IVDE with EH where double adjacent ventral slots was used in a treatment of such lesion.

A 6-year-old Border Collie presented with a 4-month history of progressive plantigrade stance of the right hindlimb, following a jump when chasing a ball. Avulsion of the lateral head of the gastrocnemius and tearing of the medial muscular belly were confirmed radiographically and ultrasonographically. Surgical repair of the lateral head was performed using two nylon mattress sutures placed around the fabella and through femoral condylar bone tunnels, followed by the application of a cranial half cast for 5 weeks. No complications were reported and follow-up owner's questionnaire at 18 months postoperatively revealed excellent results with the dog returning to normal activity.Avulsion of the lateral fabella was induced in a cadaveric limb and hyperflexion of the tarsus was simulated. Extreme hyperflexion of the tarsus only occurred once a subsequent tear of the medial belly of the gastrocnemius had developed, but without avulsion of the medial fabella.

Objective We aimed to provide repeatable methods for quantifying antebrachial valgus and rotation in dogs with and without complex angular deformities. Thus, we investigated the repeatability of two methods to measure carpal valgus and one method to measure external rotation of the thoracic limb in a standing position. Study Design This was a prospective observer agreement study with a sample of 18 non-chondrodystrophic dogs as baseline and 43 chondrodystrophic dogs. The rotation measurements (ROT), modified valgus measurements (VALG-M), and established carpal valgus measurements (VALG) were done independently by two investigators. Repeatability was assessed with intraclass correlation coefficient (ICC). Results The measured mean (± standard deviation) angles of ROT, VALG-M, and VALG for non-chondrodystrophic dogs were 14 degrees (± 5 degrees), 9 degrees (± 4 degrees), and 4 degrees (± 3 degrees) and 30 degrees (± 13 degrees) and 23 degrees (± 11 degrees) for ROT and VALG-M for chondrodystrophic dogs respectively. In non-chondrodystrophic dogs, ICC was low with mean errors of 1 to 6 degrees, whereas in chondrodystrophic dogs, intra- and intertester ICC was high for ROT and VALG-M with mean errors of 3 to 8 degrees. Conclusion The ROT and VALG-M methods can be used as reliable tools to objectively quantify aspects of thoracic limb alignment for research, clinical, and screening purposes in both non-chondrodystrophic and chondrodystrophic dogs. The mean values of ROT, VALG-M, and VALG can be used as references for non-chondrodystrophic dogs in the standing position.
