Short-term comparison of tibial tuberosity advancement and tibial plateau levelling osteotomy in dogs with cranial cruciate ligament disease using kinetic analysis

OBJECTIVESnThis study set out to compare the outcomes of tibial tuberosity advancement (TTA) and tibial plateau levelling osteotomy (TPLO) procedures in the treatment of dogs affected with unilateral cranial cruciate ligament disease (CCLD) based on subjective parameters and objective pressure platform analysis (baropodometry).nnnMETHODSnTwenty-seven adult dogs weighing over 20 kg that were presented with unilateral CCLD and were treated by the TTA (12 dogs) or TPLO (15 dogs) surgical procedure. Patient allocation to either group was based on tibial plateau angle (TPA), according to clinical guidelines (indication for TTA for dogs was a TPA up to 25°, and indication for TPLO was any TPA). Pressure platform analysis was performed prior to surgery and at four different postoperative time points (14, 30, 60 and 90 days).nnnRESULTSnLimb function significantly improved following TTA and TPLO, with no significant differences between groups.nnnCONCLUSIONnThe TTA and TPLO surgical procedures were considered to be equally effective in promoting weight bearing capacity recovery in dogs affected with unilateral CCLD under the conditions of this trial.

Remoção de pino de Steinmann intra-abdominal por videolaparoscopia em um cão

An intra-abdominal Steinmann pin was detected during a radiographic assessment of the 60th post- operative day of a vertebral stabilization in a dog. Laparoscopic inspection and retrieval of the foreign body were performed. The implant was surrounded by omentum with no noticeable signs of infection. The procedure was performed within 15 minutes with minimal trauma. To the authors knowledge, this is the first report of this kind of implant migration to the peritoneal cavity followed by laparoscopic removal in dogs.

Osteossíntese de fêmur em gato-do-mato-pequeno (Leopardus tigrinus)

The little spotted cat or oncilla (Leopardus tigrinus) is a wild feline that has size and body proportions similar to the domestic cat (Felis catus), but can be classified as the smallest wild feline all the way from Costa Rica to Brazil and Argentina threatened with extinction. In domestic cats, the distal portion of the long bone femur is more susceptible to fractures. The aim of this paper is to report the treatment of a complete, transverse, supracondylar fracture of the right femur on a five-month-old little female oncilla, by internal fixation by two crossed Kirschner wires. At 60 days after surgery, the patient was discharged from the veterinary hospital and returned to its place of origin. Considering the authors knowledge, this is the first report of osteosynthesis in L. tigrinus using this described technique. Due to similarities with species, anatomical, surgical and anesthetics data of domestic cats were considered. The fixation method was successful and limb function was achieved without any complication.

Fratura proximal de tíbia após cirurgia extracapsular para correção de ruptura de ligamento cruzado cranial em cão

Cranial cruciate ligament rupture (CCLR) is one of the most common orthopedic diseases in dogs and extracapsular suture with nylon is often used for its correction. This technique may be associated with incisional complications, post-surgical meniscus injury, swelling associated with suture material and infection. The objective of this study is to report a tibial fracture in a dog, caused by complications after an extracapsular suture for the repair of CCLR. An adult dog, which suffered a tibial fracture after an extracapsular fixation for a CCLR, underwent surgery for the fixation of the fracture with a 2.0mm plate, by a referring veterinarian, but the implant failed. The plate was removed and the fracture was stabilized with a circular fixator. Bone consolidation was observed after 120 days.

Osteossíntese de mandíbula e maxila em equinos adultos: relato de quatro casos

Secondary mandible fracture due to external trauma is not uncommon in horses, that being the most commonly fractured bone when the injure is on the animal´s head. In most cases, the injuries are open and damaging to surrounding soft tissues. As the bones of the head are not subjected to load forces, the support requirements for fracture fixation are less challenging. This paper describes the surgical treatment of four mandible fractures in horses, and, in one case, the animal had also suffered a fractured jaw. Four horses with a history of trauma to the head region have been examined, clinically and radiographically evaluated, and after being diagnosed, each of them was submitted to surgical treatment. In the first case, the horse showed rostral fracture of the jaw, thus being treated with cerclage. Moreover, the animal had multiple jaw fractures that were fixed with a cerclage next to the incisors, with a plate and two screws and cerclage in the region between the incisors and the premolars. The second animal had multiple fractures of the horizontal and vertical branches of the right jaw and was treated with the use of five reconstruction plates and screws. The third patient was diagnosed with a simple horizontal branch fracture of the left mandible that was stabilized with a plate and screws. The fourth patient had a fracture of the rostral mandible with avulsion of four incisors, and received the extraction of incisors and labial mucosa suture. All animals received fracture treatment in different post surgical periods, allowing improved quality of life.
