To evaluate the use of the FESSA hinged linear transarticular external fixator (HLTEF) and the effect of early physical therapy after experimental stifle luxation in pigeons, eight feral pigeons (Columba livia domestica) underwent surgery and afterwards one group started physical therapy on day 1 post surgery, while the other after HLTEF removal on day 21. Healing was evaluated with clinical, radiographic, pathologic, and histologic criteria for 43 days. All birds healed clinically and radiographically. No significant difference was detected between groups in range of motion, thigh thickness and circumference, or muscle/ joint histology. Regressive lameness and pododermatitis affected all birds. Pathology revealed joint capsule fibrosis, hemorrhagic synovial fluid, and callus formation around the pins. Degenerative joint changes were evident histologically. Concluding, this study demonstrated the successful use of the FESSA hinged linear transarticular external fixator for the treatment of stifle luxation and emphasized the difference between clinical and histological healing outcome.
