Uso de enxerto autógeno de fáscia lata no tratamento de defeito segmentar crônico do tendão calcâneo comum em felino doméstico / Use of autogenous fascia lata graft in the treatment of chronic segmental defect of the common calcaneus tendon in domestic feline

Background: The common calcaneus tendon is formed by the common tendon of the femoral biceps muscle, tendon of the superficial digital flexor muscle and gastrocnemius muscle tendon, and its rupture is related to acute traumas in small animals. Among some applications described, surgical repair can be adopted in the correction of tendon ruptures and the use of grafts may be indicated in some severe lesions, where it is not possible to perform tenorrhaphy. This study aims to report the case of a feline with rupture of the common calcaneus tendon in which the tenorrafia associated with the autogenous fascia lata graft was performed as adjuvant to the cicatrization of the same.Case: A 24-month-old, undefined male feline with approximately 3 kg was treated at the FCAV Veterinary Hospital, UNESP Jaboticabal, State of São Paulo, Brazil, with a history of falling, for approximately two weeks, and has since plantigrade posture. Upon physical examination, it was possible to identify a discontinuity of the common calcaneus tendon. The radiographs were performed, which did not show any bone changes. A hemogram and biochemical profile were performed, which were within normal limits. The patient underwent surgery, and a complete lesion of the common calcaneus tendon was identified, with a chronic aspect. Approximation of the stumps was impossible, so a flap of fascia lata, about two centimeters long and one centimeter wide, was removed, which was used as a bed and tendon support for tendon growth. After removal all of the present fibrosis, the tendon stumps were approximated by means of modified Kessler suture with mononylon thread, and fascia lata flap of the ipsilateral limb was sutured with separate single points in both tendon ends and in their lateral and medial portion. In the tibiotarsic joint, the external skeletal fixator type II was used for immobilization, during a period of 30 days.[...]

Instabilidade atlantoaxial em cães: fisiopatologia, abordagens clínico-cirúrgicas e prognóstico / Atlantoaxial instability in dogs: pathophysiology, clinical-surgical approaches and prognosis / Inestabilidad atlantoaxial en perros: fisiopatología, enfoques clínico-quirúrgicos y pronóstico

A instabilidade da articulação atlantoaxial é uma afecção comum entre cães de raça de pequeno porte, e os sinais clínicos desenvolvem-se com menos de dois anos de idade, geralmente são progressivos e o paciente apresenta hiperestesia cervical, ataxia proprioceptiva, e em casos severos paraplegia. A instabilidade pode gerar subluxação dorsal do axis em relação ao atlas, levando a uma lesão medular em diferentes níveis. Alterações congênitas, como ausência ou hipoplasia do processo odontóide e ligamentos, ou traumáticas, como fraturas do processo odontóide e ruptura dos ligamentos estão envolvidas na fisiopatologia da afecção. O diagnóstico pode ser realizado com auxílio de radiografias lateral e ventrodorsal com a região craniocervical em posição neutra. O tratamento clínico é a escolha primária e faz-se o uso de colar cervical por três meses, confinamento e corticosteróides. Exceção a este tratamento são pacientes com apresentação clínica severa ou refratários ao tratamento conservativo, nestes casos indica-se a cirurgia para estabilização por meio de abordagens ventrais ou dorsais. Observou-se que as técnicas cirúrgicas ventrais apresentam maiores índices de sucesso e menores recorrências de recidivas, contudo, as estabilizações cirúrgicas continuam a ser um desafio pela elevada taxa de complicações e óbitos transoperatórios.

The instability of the atlantoaxial joint is a common condition among dogs small breed, and clinical signs are developed under two years of age, are usually progressive and the patient presents cervical hyperesthesia, ataxia proprioceptive, and in severe cases tetraplegia. The instability can generate subluxation dorsal of axis in relation to the atlas, leading to spinal cord injury at different levels. Congenital abnormalities, such as absence or hypoplasia of the odontoid process and ligaments, or traumatic, such as fractures of the odontoid process and rupture of ligaments are involved in the pathophysiology of the disease. The diagnosis can be performed with the aid of lateral X-rays with the DV region craniocervical in neutral position. Clinical treatment is the primary choice and makes the use of cervical collar for three months confinement and corticosteroids. Exception to this treatment are patients with severe clinical presentation or refractory to conservative treatment in these cases is indicated surgery to stabilize through the ventral or dorsal approaches. It was observed that the ventral surgical techniques have higher success rates and lower recurrence of relapse, however, surgical stabilization remains a challenge due to high rate of intraoperative complications and death.

La inestabilidad puede generar eje dorsal subluxación en relación con el atlas, lo que lleva a una lesión de la médula espinal en los diferentes niveles. Anomalías congénitas, tales como ausencia o hipoplasia de la apófisis odontoides y ligamentos, o traumática, tales como fracturas de la apófisis odontoides y la rotura de los ligamentos están implicados en la fisiopatología de la enfermedad. El diagnóstico se puede realizar con la ayuda de los rayos X en la región lateral VD craneocervical en posición de punto muerto. El tratamiento clínico es la elección primaria y hace que el uso del collarín cervical durante tres meses de confinamiento y corticosteroides. Excepción a este tratamiento son los pacientes con presentación clínica grave o refractario al tratamiento conservador en estos casos la cirugía está indicada para estabilizar a través de los enfoques ventral o dorsal. Se observó que las técnicas quirúrgicas ventrales tienen mayores tasas de éxito y menor recurrencia de recaídas, sin embargo, la estabilización quirúrgica sigue siendo un desafío debido a la alta tasa de complicaciones intraoperatorias y muertes.

Hansen type II disc disease in dogs: pathophysiology, clinicalsurgical approach and controversies / Doença do disco intervertebral Hansen tipo II em cães: fisiopatologia, abordagem clínico-cirúrgica e controvérsias

Protrusion of the intervertebral disc can cause chronic progressive compression of the spinal cord, and the neurological associated signs vary according to anatomical location, duration and dynamic force of compression. The type II disc disease is not fully understood, and there are many controversies about is clinical significance and best form of treatment. The most important aspect of conservative treatment is rest and physiotherapy associated with mild exercise, and use of corticosteroids to reduce vasogenic edema. The spinal decompression by surgery for removal of disc material from within the medullary canal is the surgical treatment of choice in type I disc disease, but has technical limitations in the type II disc disease. The purpose of this paper is to review the pathophysiology and treatment of chronic intervertebral disc disease and discuss the controversies in medical treatment and the use of some traditional and new surgical techniques.(AU)

Lumbar myelography in the diagnosis of thoracolumbar intervertebral disk extrusion in dogs: prospective study / Mielografia lombar no diagnóstico de extrusão do disco intervertebral toracolombar em cães: estudo prospectivo

Thoracolumbar disk extrusion is the most common cause of extradural compression of the spinal cord in dogs. Myelography is one of the most commonly performed techniques for the diagnosis of this affection. This study aimed to evaluate the applicability and effectiveness of lumbar myelography in the diagnosis of thoracolumbar intervertebral disk extrusion in dogs, as well as its major complications. Twenty dogs were used in this study. Animals were included when neurological examination suggested thoracolumbar spine lesion, myelography was used as a complementary diagnostic method, and diagnosis of disk extrusion was surgically confirmed. The accuracy of the exam to predict location and lateralization of extruded disk material were evaluated, as well as complications associated to the procedure. Lumbar myelography exhibited 95% and 60% accuracy for location and lateralization of the lesion, respectively, with minimal complications.(AU)

Axis fracture repair with locking plate in dog

Background: Cervical fractures in dogs occur most commonly in the cranial region, mostly requiring surgery. Various types of implants are being used while fixation using plate is poorly described in the literature. The plate and screw types are a limiting factor since they can lead to loss of stability due to loosening of the screws. The use of locking plates has been advocated, which does not allow movement between the screw-plate-bone, providing extreme stability and rigidity to the system. This study describes the use of locking bone plate to stabilize axis fracture in a dog and the results obtained with this technique. Case: A 9-month-old male Poodle presented due to a history of trauma to the cervical spine caused by a fall of an object. Upon physical examination, the patient was alert and physiological parameters within the normal reference limits. However, neurological examination showed tetraplegia, hyperreflexia, preserved nociception and much cervical pain. There were no changes in the cranial nerves test. Cranial cervical lesion was initially suspected and the patient was rigidly fixed on a flat surface. The radiographic examination showed a fracture of the second cervical vertebra (axis) with anatomical axis deviation, and the patient was referred for surgery. After anesthesia, the dog was positioned dorsal decubitus and rigidly fixed on the operating table with the thoracic limbs pulled caudally. The surgical approach of the cranial cervical spine started through the ventral access until complete visualization of the fracture line and the caudal portion of the axis body. After perfect apposition and alignment of the bone fragments, rigid stabilization was performed using locking plate and screws. The patient had a favorable neurological recovery, and five days after the surgery, no change was observed in locomotion and postural reactions, besides the absence of neck pain. Discussion: The implant used in this study was small and displayed a good fit along the body axis. The locked system allowed the bolt head to lock in the hole of the plate, forming a bone-screw-plate unit that prevents its failure. In our case, the tip of the caudal screws protruded approximately two millimeters within the spinal canal, without any apparent effect on the outcome. In a previous study, in which plates were used for ventral fixation and stabilization of the atlantoaxial joint, the screws also protruded into the vertebral canal without causing any problems, presumably because the cervical vertebral canal is wider than the diameter of the spinal cord at this location. Failure rate of up to 44% has been reported for all the processes of atlantoaxial ventral fixation if the surgery is deemed successful when resolution of neurological signs occurs, and there is no need for further surgery. According to this, the present case can be considered successful taking into account the clinical outcome after surgery, the rapid reduction of pain, return to ambulation and the absence of neurological deficits. We conclude that the locking plate was a viable alternative to other fixation techniques for fractures involving the second cervical vertebra in small animals since it allowed relative stability of the fracture and an excellent neurological recovery of the patient.

This study aimed to evaluate the applicability and effectiveness of lumbar myelography in the diagnosis of thoracolumbar intervertebral disk extrusion in dogs, as well as its major complications. Twenty dogs were used in this study. Animals were included when neurological examination suggested thoracolumbar spine lesion, myelography was used as a complementary diagnostic method, and diagnosis of disk extrusion was surgically confirmed. The accuracy of the exam to predict location and lateralization of extruded disk material were evaluated, as well as complications associated to the procedure. Lumbar myelography exhibited 95% and 60% accuracy for location and lateralization of the lesion, respectively, with minimal complications.

A extrusão do disco toracolombar é a causa mais comum de compressão extradural da medula espinhal em cães. A mielografia é uma das técnicas mais comumente realizadas para o diagnóstico desta afecção. Objetivou-se avaliar a aplicabilidade e efetividade da técnica de mielografia lombar no diagnóstico de extrusão do disco intervertebral toracolombar em cães, bem como suas principais complicações. Foram utilizados 20 animais que ao exame neurológico apresentaram localização da lesão na região toracolombar e que tiveram indicação de mielografia como método diagnóstico complementar e confirmação do diagnóstico de extrusão do disco no trans-operatório. Avaliou-se a precisão do exame na localização e lateralização da lesão, e as complicações associadas ao procedimento. A mielografia lombar teve acurácia de 95% e 60% para a localização e a lateralização da lesão respectivamente, com complicações mínimas.
