Surgical arthrodesis is effective for treating proximal interphalangeal joint (PIJ) injuries in horses. Despite several techniques described so far, the use of a 3-hole, 4.5mm-locking compression plate, associated with two 5.5-mm transarticular cortex screws, is currently considered the "gold standard." This review describes the anatomy of the pastern, as well as causes, indications, and possibilities for arthrodesis in the equine PIJ. A description of the current surgical technique for joint fixation is also presented.(AU)

Background: Radio-carpal dislocations are normally related to situations of trauma and may be treated with open or closed reduction, reconstruction of injured structures or arthrodesis. The treatment aims to eliminate pain, abnormal joint movement and restore member functions, avoiding or minimizing the development of arthrosis. Notwithstanding the literature on the treatment options, few of them explain the restorative technical applications and their evolution in a later postoperative period. The aim of the present report is to discuss extra-articular joint reconstruction with nylon wire in a canine patient with radio-carpal joint dislocation and ligament rupture. Case: A 10-year-old mixed-breed bitch, weighing 10 kg, after an 8-meter fall, received care at Animal Care Barueri Clínica Veterinária. The animal presented left thoracic member functional impotence and radio-carpal joint valgus dislocation, pain and joint swelling. The patient was sedated and medium-lateral and dorso-palmar X-rays of the distal area of the thoracic member were performed, showing radio-carpal dislocation and a slight radiotransparent line in caudal cortical of the middle third of the left radium, possibly related to an incomplete fracture due to compaction. At this point, the choice was for a closed reduction performed by means of traction followed by internal rotation of the distal extremity of the member. An immobilization device was placed using a vinyl splint for 4 days, until the date of the surgery. For the surgical procedure, a dorso-medial access was opened in the left radio-carpal joint, restoring the short radium collateral joint with nylon 0 suture, anchored on 3 pathways opened in the bones (2 pathways in the radium and 1 in the carpo-radial bone), forming one knot. The subcutaneous tissue was closed and sutured using absorbable wire of 2-0 polyglycolic acid. The skin was sutured using nonabsorbable wire of 3-0 nylon. The immediate postoperative X-rays showed the pathways created, conservation of the bone structures and restoration of the anatomic axis of the radio-carpal joint. The member was again immobilized for 70 days and, 30 days after removal of the splint, the animal could already bear load over the member, without lameness. At 10 months after the surgery, the patient performed X-rays of the medium-lateral and dorso-palmar projections, showing absence of the signs of arthrosis or any joint impairment. There was also absence of lameness and pain, however with reduction in joint movement amplitude, with total extension but more limited flexion. Discussion: Through comparison with the literature it was possible to find similarities with the joint injury approach reported, mainly regarding the form of the suture and the clinical alterations observed, such as short radium collateral ligament rupture related to joint valgus deviation. The treatment strategy in the case combined temporary closed reduction of the joint, immobilization, later joint access and restoration with synthetic wire and long-term immobilization. The postoperative results obtained showed favorable evolution, without signs of joint degeneration, pain or lameness. Possible unwanted consequences related to arthrodesis make the options for reconstruction techniques seem more interesting; however, further information of their application and the combination of its variations in a more directed fashion are still required. Understanding the types of injuries, together with the development of research that assess their diagnosis and evolution, may help treatments to show even better perspectives.

Background: The metacarpal/metatarsophalangeal joints, as well as the suspensory apparatus, are usually affected by injuries, due to the intense physical demand during sports and great range of motion, predisposing to degenerative processes,trauma and rupture of the suspensory apparatus. In this case, arthrodesis is the main technique indicated. Such surgicaltechniques have a poor prognosis due to post-surgical complications, such as implant infection. Therefore, the study ofprocedures that promote better joint stabilization is important, with reduced surgical time and tissue exposure, decreasingsignificantly the chance of infection and other possible complications.Case: A 5-year-old male horse was referred to the hospital with a history of trauma and a lacerating wound in the metatarsalplantar region of the left hindlimb. The animal presented grade IV (I-V) claudication of the left hindlimb with hyperextension of the metatarsophalangeal joint and significant pain on palpation, evidencing the rupture of the superficial, deep digitalflexor tendons and suspensory ligament of the fetlock. The initial surgical treatment was performed using the arthrodesistechnique described by [16]. The intramedullary nail was used with fixation of the plate on the plantar face of the first phalanx together with a single plate fused to the pin, adjusted according to size of the first phalanx, 13 mm thick x 15 cm long,forming an angle between 120º and 140º. Twenty-four h after surgery, there was a simple spiral diaphyseal fracture (typeA), in the middle third of the third metatarsal bone in the region of the proximal end, due to the lever held by the short nailagainst the diaphysis cortex. To treat the complication, an intramedullary 316 L surgical steel rod 13 mm thick x 21 cm longwas used, filling the entire spinal canal. The nail had three holes at the proximal end and two holes at the distal end...

Background: The metacarpophalangeal and metatarsophalangeal joints are very demanded during high intensity exercises,and may be affected by osteoarthritis, fractures, luxations and rupture of the suspensory apparatus. Thus, arthrodesis maybe indicated to restore joint stability and accelerate the ankylosis process. The most commonly used surgical techniqueshave been associated with postoperative complications, including infection and failure of the implants, so it is importantto develop procedures that are less invasive procedures and promoting stable fixation. Therefore, the aim of this work isto report the use of the modified steel basket technique for metatarsophalangeal arthrodesis in a foal with hyperextensionof the joint due to rupture of the digital flexor muscles.Case: A 2-day-old male foal was admitted to clinical care, presenting multiple cutaneous wounds caused by dogs bites,located in the tarsus and thigh of the hindlimb. The animal presented in standing position and had no difficulty of movement,being initially treated through daily cleaning of the cutaneous wounds and systemic antibiotic therapy. Hyperextension ofthe metatarsophalangeal joint was evidenced after 20 days, being approached through tenotomy and tendon shortening,followed by tenorrhaphy and immobilization for 30 days. Due to the failure of the treatment, it was opted for metatarsophalangeal arthrodesis by modified steel basket technique. The procedure involved the implantation of a steel basket of25.0 mm in diameter x 25.0 mm long in a 24.0 mm hole created on the dorsal surface between the third metacarpal andthe proximal phalanx. The basket was filled with bone extracted from drilling and fixed with two cortical screws at anangle of 25° toward proximoplantar and distoplantar direction. Immobilization of the limb was performed postoperativelywith synthetic plaster cast for 45 days and, due to the persistence of lameness...

Background: Tibiotarsal joint luxations are mostly traumatic and due to automobile accidents. The arthrodesis of this joint is considered the final solution for trauma with ligament lesions without repair, luxations without possibility of joint recovery and chronic joint diseases. The direction to which the joint is dislocated is associated with the forces of trauma, and bilateral ligament injuries are not uncommon. However, the medial ligaments are more frequently injured. The aim of this study is to describe the performance of pantarsal arthrodesis using a customized titanium plate for application to the medial surface of the joint.Case: An undefined breed dog, weighing 21.5 kg, was attended at the Veterinary Hospital of the Federal University of Lavras (UFLA) with history of trauma and injury in the right pelvic limb. After physical and radiographic examinations it was diagnosed with an exposed luxation of the tibiotarsal joint and tissue loss in the region. The tibiotarsal region was cleaned and a bandage was made daily until the first surgical procedure, which occurred five days later. Initially, it was treated without success with the use of a transarticular external fixator1 . Subsequently, pantarsal arthrodesis was performed using a customized titanium angled plate (Made by a private manufacturer based on the functional angulation of the tibiotarsal joint of the contralateral limb). The joint was accessed for exposure of the distal portion of the tibia, tarsal and metatarsals bones. Wear of the articular surfaces was performed and then the customized angulation plate for pantarsal arthrodesis was placed on the medial side of the joint. Bicortical drillings were performed, starting with the proximal orifice. According to the holes of the plate, five 3.5 mm diameter screws1 (four at the distal tibia and one at the tarsus) and four 2.7 mm diameter screws were used in the metatarsal bones.[...](AU)

The objective of this work was to report the case of a dog with limb claudication of the right pelvic limb five months ago, using intramedullary pin associated with the LC-LCP plate in the surgical treatment. The surgical approach was made cranial to the tibiotarsal joint, applying the normalized 3mm intramedullary pin through the tibia to the calcaneus. A nine-hole 3.5 mm LC-LCP plate was applied associated with the pin using four proximally locked bolts and three distal locked bolts. On the eighth postoperative day, the animal returned daily activities while maintaining the integrity of the implant. The association of intramedullary pin with LC-LCP plaque promoted additional stability, thus reducing complications, which allowed us to introduce another alternative for the performance of pantarsal arthrodesis in dogs.(AU)

Objetivou-se com este trabalho comparar biomecanicamente os posicionamentos dorsal e medial da placa bloqueada na artrodese do carpo em cães. Para isso, foram utilizados sete pares de membros torácicos de cães eutanasiados por razões não relacionadas ao estudo, em que sete membros foram estabilizados com placa dorsal, e seus respectivos pares com placa em posicionamento medial. Os membros com as articulações radiocarpometacarpianas estabilizadas cirurgicamente foram submetidos a ensaio de compressão axial em máquina universal de ensaios de materiais, e os dados de limite de elasticidade, rigidez estrutural, carga máxima e carga no momento da fratura dos posicionamentos foram comparados por meio do teste de Student-Newman-Keuls, a um nível de significância de 5%. Todos os membros foram fraturados no terço distal do terceiro metacarpo; nos membros com placa dorsal, a fratura ocorreu distal ao orifício distal e, nos membros com placa medial, a fratura ocorreu no último orifício dos metacarpos dois e três. Não houve dobra ou quebra de placas e parafusos e não houve diferença significativa entre os posicionamentos dorsal e medial dos implantes quanto aos parâmetros avaliados.(AU)
The aim of this study was to compare biomechanically the dorsal and medial positions of the locking plates on carpal arthrodesis in dogs. For this, seven pairs of thoracic limbs of dogs were used, in which seven limbs were stabilized with dorsal plate and seven limbs with plate in medial positioning. The members with the surgically stabilized radiocarpal-metacarpal joints were submitted to axial compression testing in a universal testing machine and the yield load, structural rigidity, maximum load and ultimate load of the positioning were compared by Student-Newman-Keuls test at a significance level of 5%. All members fractured in the distal third of the third metacarpal, in the limbs with dorsal plate the fracture occurred distal to the distal hole and in the members with medial plate the fracture occurred in the last hole of the metacarpals two and three. There was no bending or broken implants. There was no significant biomechanical differencebetween the dorsal and medial positions of the implants.(AU)

The purpose of this study was to describe a pantarsal arthrodesis using a medial locking plate in an overweight dog. A 5-year-old, 28 kg, female dachshund presented with a left plantigraded hindlimb with calcaneous osteolytic injury and bone exposure. First, the patient was treated for the skin wound and started on a weight-loss program. A customized locking plate was used in the pantarsal arthrodesis. A normal hindlimb position and gait were observed after 27 days, and bone fusion was achieved at 60 days postoperatively. Implant removal was performed at 120 days, and the patient was discharged. The dog was kept on weight-loss therapy until it achieved a body weight of 11 kg. The customized bone implant used for pantarsal arthrodesis proved feasible and effective in treating an obese dog with low bone density.

Background: Humeral fractures account for 13% of all fractures in cats and commonly affect the middle diaphysis and supracondylar region with comminution. They are usually the result of high energy traumas such as falls, car accidents and firearm injuries. There are few treatment options for these types of fractures and since they are joint injuries, early surgical repair is mandatory to achieve perfect anatomical reduction, to maintain joint congruence and to allow early weight bearing. Our purpose is to report four subacute and chronic fractures of the distal diaphysis associated with comminuted supra and intercondylar fractures, stabilized with transarticular external skeletal fixator in three domestic felines. Cases: (1)- A 3-year-old male docile Siamese cat with 3.7 kg of body weight was presented for consultation with a 14-day history of high rise syndrome after falling from a 12-meter high. It presented distal comminuted humeral fracture that involved the inter and supracondylar regions. It also had right carpal-ulnar subluxation and comminuted right olecranon fracture involving the articular surface in the left thoracic limb. Fracture and joint stabilization was achieved by use of a transarticular hybrid external skeletal fixator on the right front limb. Fracture healing was observed at 150 days postoperatively. (2)- A 10-year-old female aggressive mixed breed cat with 4.1 kg of body weight was presented for consultation with a 16-day history of high rise syndrome after falling from a 9-meter high. The cat had a comminuted right humeral articular fracture with supra and intercondylar involvement and scapular fracture on the contralateral limb. The humerus fracture was treated with a transarticular linear external skeletal fixator and fracture healing was obtained at 240 postoperative days [ ]
