Resumo
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...
