This report described the clinical case of a gelding, approximately 13 years old, mixed breed, with concomitant ruptures in the forelimbs, including the left palmar carpal ligament and the right superficial digital flexor tendon. After the clinical examination, it was observed severe hyperextension in the carpal joint and swelling, heat and intense pain in both thoracic limbs, in addition to reluctance to move and severe degree of lameness. In the radiographic examination, the right forelimb showed hyperextension of the radiocarpal joint with 225° and the presence of lateral subluxation of the carpal-ulnar bone and the left forelimb had hyperextension of the same joint with an angle of 235°. After euthanasia, partial multifocal tearing of the carpal palmar ligament was observed in the left thoracic limb and total tearing of the superficial digital flexor tendon in the right forelimb. This study presented the case and discussed the possible causes of the occurrence of concurrent ruptures. Also, the report explored equine carpal hyperextension, a rare condition with limited recovery records following palmar carpal ligament rupture injuries. It emphasizes the biomechanical role of this ligament, and its synergy with the superficial digital flexor tendon in preventing hyperextension. Although tendon ruptures have treatment options, complete rupture of the palmar carpal ligament often leads to euthanasia due to irreparable joint damage.Descargas
