Tratamento do rádio curvo em cão jovem com associação das técnicas de grampeamento fisário radial, ostectomia ulnar e fixador externo dinâmico transarticular / Treatment of radius curvus in a young dog with association of radial physeal stapling, ulnar ostectomy and transarticular dynamic external fixator techniques

Background: Radius curvus is a clinical manifestation of the premature closure of the distal ulnar physis and the mostcommon physeal disease in dogs, representing 63% of all physeal injuries. There are few reports indicating the techniqueof stapling for treatment of radius curvus in squeletically immature dogs. The aim of this study is to report a case of radiuscurvus in a young dog successfully treated with a combination of 3 surgical tecniques: 1- Stapling the medial and cranialportions of the distal radial physis; 2- Oblique osteotomy of the proximal ulna and ostectomy of the distal ulna, and 3-Dynamic external skeletal fixation in the elbow joint.Case: A 5-month-old female dog was referred to the University Veterinary Hospital with a history of left thoracic limb deformity for 2 months. There was a history of possible traumatic event on the front limb, in addition to providing nutritionalsupplements daily. In the radiographic evaluation the changes were identified in the left thoracic limb: shortening of theulna, procurvatum and medial angulation of the distal radius, increased joint space and articular incongruity of the elbowjoint. The dog was subjected to surgical treatment by the combination of three main surgical techniques. For the staplingof the distal radial physis the surgical approach on the cranial-medial surface of the distal radius was made. Two surgicalstaples were positioned in the distal radial physis. Thereafter a caudal approach was made to the distal region of the ulnardiaphysis for the distal ostectomy of the ulna. A bone segment of 1 cm in length of the distal ulnar diaphysis was removed.Another caudal approach was made to the proximal region of the ulnar diaphysis and a proximal oblique osteotomy of theulna was performed. For the dynamic external skeletal fixation in the elbow joint two Steinmann pins were inserted. Thefirst pin was proximal to the supracondilar...

Tratamento conservativo e cirúrgico em 22 ruminantes com fraturas em membros / Conservative and surgical treatment in 22 ruminants with limb fractures

O objetivo do presente trabalho foi relatar os principais locais de fraturas em membros de 22 ruminantes e determinar a eficiência dos tratamentos utilizados. Foram incluídos no estudo oito caprinos, oito ovinos e seis bovinos Em casos de fraturas distais, o tratamento conservativo com imobilização foi o método de eleição. Em casos de fraturas proximais e fraturas expostas de metatarso ou metacarpo, os ruminantes foram tratados cirurgicamente. Observou-se maior frequência de fraturas envolvendo o metacarpo ou metatarso (54,5%), seguido por fraturas de tíbia (22,7%), fêmur (9%) e casos isolados de fraturas de falange medial, úmero, rádio e ulna (4,5% cada). O índice de recuperação total alcançou 95,4%. A imobilização com gesso associada à tala de Thomas, ou apenas com talas de madeira em animais jovens, foi eficiente na redução de fraturas de metacarpo, metatarso, tíbia, úmero e rádio nos ruminantes tratados. Enquanto no caso de fratura de falange medial, a imobilização com uso apenas de gesso foi suficiente para proporcionar reparação óssea adequada. A fixação esquelética externa ou interna deve ser considerada uma opção no tratamento de fraturas metacárpicas, metatársicas, tibiais e femorais em ruminantes, principalmente quando o animal for de baixo peso corporal.(AU)

The aim of the present study was to report the main locations of limb fractures in 22 ruminants and to determine the efficiency of the treatment choices. Eight goats, eight sheep and six cattle were included. In cases of distal fractures, the conservative treatment with immobilization was the method of choice. In cases of proximal, exposed metatarsal or metacarpal fractures, the ruminants were treated surgically. The higher frequency of fractures involved the metacarpal or metatarsal (54.5%) followed by fractures of the tibia (22.7%), femur (9%) and isolated cases of medial phalanx, humerus, radius and ulna fractures (4.5% each). Total recovery rate reached 95.4%. Immobilization with plaster associated with Thomas splint, or just with wooden splints in young animals, was efficient in reducing fractures of metacarpal, metatarsal, tibia, humerus, and radio in the treated ruminants. In the case of medial phalanx fracture, immobilization using only plaster was sufficient to provide adequate bone repair. The internal or external skeletal fixation should be considered an option in the treatment of metacarpal, metatarsal, tibial and femoral fractures in ruminants, especially in low body weight animals.(AU)
