“…Lumbar vertebral fractures in dogs occur mostly after road traffic accidents and are often characterised by fracture of the caudal part of the vertebral body (Beaver et al 1996, Harrington & Bagley 1998, Segal et al 2018. Most of them required surgery to alleviate intense pain.…”

“…Most of them required surgery to alleviate intense pain. The most common surgical technique uses a lateral approach to implant screws or pins through the vertebral body (Wong & Emms 1992, Beaver et al 1996, Jeffery 2010, Livet et al 2016, Segal et al 2018). In the L6 region, the iliac wings around L6 and L7 interfere with this lateral implantation.…”

To assess the feasibility and outcome of pedicle screw implantation on sixth lumbar vertebral body fractures.Materials and MethOds: Dogs with sixth lumbar vertebral body fractures stabilised using L6 and L7 (±L5) pedicular implantation via a dorsal approach preferentially and conventional vertebral body implantation otherwise were reviewed. Coaptation was made with bone cement. Complete neurological examination, pre and postoperative imaging consistent with L6 body fracture (radiographs ± CT scan) and follow up including clinical examination and radiographs 3 to 5 weeks post-operatively were required as inclusion criteria. When available, owner interview and/or clinical examination and imaging (radiographs ± CT scan) at least 1 year after surgery were reported.results: Five dogs met the inclusion criteria. Dorsal pedicle screws implantation was feasible in all L7 vertebrae and in four L6 vertebrae. Adequate implantation was observed in all of the post-operative radiographs and on all of the three CT scans available. At 3 to 6 weeks after surgery, neurological status and locomotion were normal in four dogs, while one dog suffering from severe sciatic neuropathy did not regain normal locomotion. At least 1 year after surgery, clinical outcome was excellent for four dogs and imaging by radiography and CT scan were available for three dogs and showed complete healing of the fracture and correct positioning of the implants. The dog suffering from sciatic neuropathy had a further trauma and was euthanased 7 weeks after the surgery. clinical significance: In this case series, pedicle screw implantation achieved stabilisation of L6 vertebral body fractures, with full recovery observed in four out of five dogs. Further studies are required to confirm the safety and the effectiveness of this intervention.

“…23 While a large range of bone displacements can occur, a cranio-ventrally displaced sacral segment, along with an oblique caudo-ventral wedge fracture of the L7 vertebral body is most frequently observed. 24 Conservative management is often used successfully, with analgesia and strict rest being included in the regimen. 25 Surgical management is also an option, for example trans-ilial-pinning.…”

When we analysed the data based on the breed categories, we observed a statistical difference only in the HLR of L7.…”

Lumbosacral Biometrics and its Relevance to Patient-Specific Evaluation of Bone Mechanical Strength in Some Canine Breeds

Lumbosacral problems are commonly encountered in canine practice. However, breed specific biometric data of the lumbosacral vertebrae are lacking. Such biometric data may be useful to assess the predisposition of an individual animal or breed to lumbosacral defects, or in the events of such defects may help select an optimal surgical correction strategy. This study used digital radiographs and dissections of cadavers to develop the following biometric parameters of lumbar vertebra 7 and the sacrum: Area-Mean Grey Value Ratio (AMR) and Height-Length Ratio (HLR). The AMR and HLR values were compared between the following four canine breed categories i.e., Working Breeds (WB), Large Breeds (LB), Giant Breeds (GB) and Cross Breeds (CB). Additionally, we compared the AMR and HLR values between 10 different dog breeds. We observed significant differences in the AMR and HLR values between the various dog breeds as well as the HLR values within the canine breed categories. We consider that the differences observed in the AMR and HLR values warrant exploring the feasibility of including these biometric measurements into digital imaging systems to enhance understanding of the mechanical features of bone.

Objective To evaluate the use of String of Pearls (SOP) locking plates in thoracolumbar vertebral fractures and luxations in dogs and cats. Study design Retrospective case series study. Methods Clinical records of dogs and cats with thoracic and lumbar fractures treated in four veterinary surgical facilities were reviewed. Results A total of 26 dogs and 2 cats were included. Median weight of dogs at surgery was 12.1 kg (range: 2.7–37.2 kg) and the median weight of cats was 6.0 kg (range: 3.0–8.9 kg). Deep pain perception was negative in 25% (7/28) of animals at presentation, and 85.7% (6/7) regained deep pain sensation at discharge. Neurological status at discharge (p < 0.05) was significantly improved compared to neurological status at presentation. Complications were observed in 28.6% (8/28) of cases. Catastrophic and major complication rates were both 3.6% (1/28). Conclusion In the reported cohort of 28 dogs and cats, SOP locking plates successfully stabilized traumatic thoracic and lumbar fractures or luxations, and the rate of complications was similar to those reported using other fixation methods.
