In this case report, we present an unusual clockwise torsion of left colon around mesenteric root in a 10-month-old Arab filly, highlighting the clinical presentation, diagnostic approach and successful surgical intervention. A 10-month-old Arab filly weighing approximately 250 kg was referred with signs of acute abdominal pain. The history revealed anorexia, restlessness and severe abdominal pain that had begun the previous day. The local practitioner had previously administered flunixin meglumine, an analgesic, but it proved ineffective in relieving the pain. Upon physical examination, the filly exhibited sweating, a body temperature of 38.5°C, tachycardia (65 beats per minute) and tachypnea (25 breaths per minute). Due to the severity of the colic and the lack of response to the conservative treatments, surgical intervention was deemed necessary. An exploratory midline celiotomy was performed to evaluate the abdominal organs. During the examination, no obvious primary lesions were identified in the evaluated organs. However, a restriction in exteriorizing the left colon's length was observed. Further examination revealed an unusual clockwise torsion of the left colon that displaced in left to the right side around the mesenteric root; thereby, pelvic flexure was located in the normal anatomical position with a short length. To the best of our knowledge, this is the first reported case of clockwise torsion and an atypical displacement of the left colon in horses. The surgical correction of the displacement was successfully performed. The filly showed improvement post-surgery and did not exhibit any complications during the recovery period., (© 2024 The Author(s).

Background: One of the traumatic fractures occurring in the hindlimb of the foals is physeal fractures of the tibia. The most common type of proximal tibial fracture in foals is reported to be Salter-Harris type II., Case Presentation: This case report describes the history, clinical signs, radiographic findings, and surgical management of a proximal physeal fracture of the tibia due to the kick trauma in a 2-weeks-old Kurdish female foal, with signs of left pelvic limb lameness, valgus deviation with non-weight-bearing, non-mobility in stifle region and crepitation in the affected area. In this case, radiography was utilized to confirm the fracture and detect the exact location of the fracture fragments. The Salter-Harris type I accompanied by tibial tuberosity fracture was diagnosed. In this case, a size 4.5 mm seven-hole, T-plate, and cortical bone screws were employed to fix the physeal fracture, and a cortical bone screw was utilized to fix the tibial tuberosity in the normal position. Case follow-up during two months showed no significant complications, and the patient was fully recovered (no lameness anymore)., Conclusions: To our knowledge, this is the first report of Salter-Harris type I fracture in proximal tibia accompanied by tibial tuberosity fracture in a foal treated by a T-plate implant. A cortical screw in lag fashion for tibial tuberosity was utilized in this case for the first time, and the results were satisfying. T-Plate fixation can be recommended as an effective surgical treatment for proximal tibial fractures in foals., (© 2022. The Author(s).)
