IAEC approval reference no. (VCB/IAEC/VSR-11/2023-24) was obtained. Birds received pre-operative enrofloxacin and butorphanol, after fasting, general anaesthesia done with midazolam, ketamine and isoflurane. Tie in fixation was performed in all the birds with PMMA as connecting bar in group I and stainless steel and JESS clamps as connecting bar in group II. Post-operative care included antibiotic, analgesic administration and daily dressing for a week. Post operative clinical and radiological evaluations conducted on day 0, 7, 14, 30, 45, 60 revealed postoperative improvements in weight-bearing, gait and fracture healing in both groups. Fracture line was completely absent on day 60 and callus formation initiated by day 14. Both groups achieved fracture union by secondary healing, with varying degrees of callus formation. Axial alignment was fair initially improved to good after day 45, possibly be due to dynamization. Callus remodelling was observed by day 60, with no intergroup differences noted. Computed tomography scans confirmed fracture healing progression, supporting radiographic findings. PMMA bars provided economical and lightweight rigid stabilization, while stainless steel bar fixation was easy, consumed less time, readjustable and reusable. Complications included post-operative inflammation, knuckling, K-wire tract infections and angular malalignment. Minimal invasive closed reduction of tibiotarsal fracture repair in Aseel birds with tie-in fixation using both methods offered viable options, with distinct advantages and limitations, contributing valuable insights into avian fracture management for successful recovery and functional restoration of limb ambulation.EnglishThesis
