Association of rush pin and intramedular pin techniques for the stabilization of salter harris type I fracture in rabbit (Oryctolagus cuniculus)

Background: In domestic rabbits, fractures are usually the result of household accidents. Fractures of the distal femoral physis are frequently observed in animals with immature skeletons and may cause future orthopedic problems. With this type of fracture, early reduction and stabilization are necessary to prevent additional damage to the physis and to preserve the growth potential of the bone. This report aims to describe the clinical and radiographic findings, as well as the surgical method used that combined Rush pins with an intramedullary pin, associated with a Salter Harris type I fracture of the right distal femur in a rabbit.Case: A 4-month male domestic rabbit (Oryctolagus cuniculus) weighing 1.2 kg, was referred to the Veterinary Hospital with a right pelvic limb lameness after an episode of trauma. Orthopedic examination revealed swelling, instability, crepitation, and increased pain sensitivity in the distal aspect of the right femur. Following physical and radiographic examination, a Salter Harris type I fracture of the right distal femur was diagnosed. The patient was premedicated with a combination of xylazine (2 mg/kg IM) and ketamine (10 mg/kg IM), which allowed placement of an IV catheter for the administration of fluids and intubation using an endotracheal tube with an internal diameter of 2 mm. Anesthesia was maintained with isoflurane, and an epidural was performed with a combination of lidocaine (2 mg/kg) and bupivacaine (0.75 mg/kg). Osteosynthesis was performed with two Rush pins and an intramedullary pin. Radiographic examination 110 and 330 days after the surgical procedure showed good alignment of the bone and adequate healing of the fracture. The combination of techniques used in this case report proved to be effective, resulting in functional recovery of the limb and rapid bone healing.[...](AU)

Emprego de plasma rico em plaquetas em retalho de padrão axial da artéria genicular medial em cão: relato de caso / Use of platelet rich plasma in axial pattern flap of medial genicular artery in dog: case report / El uso de plasma rico en plaquetas en la solapa de la arteria geniculado medial en un perro: un informe de caso

As feridas de pele apresentam alta prevalência no atendimento clínico de pequenos animais, incluindo lesões provenientes de traumatismo, além de defeitos extensos decorrentes da ressecção de neoplasias. Porém problemas relacionados com a neovascularização em procedimentos cirúrgicos como presença de necrose podem estar presentes. Deste modo, o emprego do plasma rico em plaquetas em cirurgias reconstrutivas é indicado por favorecer a integração do retalho no leito receptor por meio da estimulação da angiogênese, bem como a reduzir a necrose na extremidade dos retalhos. O presente trabalho tem como objetivo relatar um caso de emprego de plasma rico em plaquetas em retalho de padrão axial da artéria genicular medial na correção de defeitos extenso proveniente da ressecção de neoplasia em cão. Os resultados evidenciam que a utilização do plasma rico em plaquetas autólogo em cirurgia reconstrutiva favoreceu a integração do retalho no leito receptor reduzindo a ocorrência de necrose na extremidade dos retalhos.(AU)

Skin wounds present high prevalence in the clinical care of small animals, including injuries from trauma, as well as extensive defects resulting from resection of tumors. However, problems related to neovascularization in surgical procedures such as the presence of necrosis may be present. Thus, the use of platelet rich plasma in reconstructive surgeries is indicated by favoring the integration of the flap in the recipient bed by stimulation of angiogenesis, as well as reducing necrosis at the end of the flaps. This paper aims to report a case of use of platelet rich plasma in the axial pattern of the medial genicular artery in the correction of extensive defects resulting from the resection of neoplasia in dogs. The results evidenced that the use of autologous platelet-rich plasma in reconstructive surgery favored the integration of the flap in the receptor bed reducing the presence of necrosis at the end of the flaps.(AU)

Las heridas de piel presentan elevada prevalencia durante la atención clínica de pequeños animales e incluyen lesiones secundarias por trauma y defectos extensos posteriores a escisión de tumores. Por lo tanto, pueden presentarse alteraciones de neovascularización y posterior presencia de necrosis tras la realización de procedimientos quirúrgicos; por esta razón, se indica el uso de plasma rico en plaquetas durante la cirugía reconstructiva para favorecer la integración del colgajo con el lecho receptor estimulando la angiogénesis y reduciendo la presencia de necrosis en el extremo de los colgajos. El presente trabajo tiene por objetivo relatar un caso mediante el uso de patrón axial de la arteria genicular medial asociado al uso de plasma rico en plaquetas para corregir un defecto extenso tras la resección quirúrgica de una neoplasia. Los resultados demostraron que la utilización de plasma rico en plaquetas autólogo favoreció la integración del colgajo sobre el lecho receptor, reduciendo la necrosis en el extremo distal del colgajo.(AU)
