A open reduction and intramedullary pinning for diaphyseal femoral fracture stabilization in a canine patient

Abstract

A two-year-old, non-descript male dog presented to the Small Animal Orthopedics Unit at the Veterinary University Peripheral Teaching Hospital with non-weight-bearing lameness in the left hind limb. Clinical examination revealed pain, swelling, and crepitus in the left thigh, with radiographic imaging in lateral and craniocaudal views confirming an unstable diaphyseal femoral fracture. Hematological evaluation showed values within normal ranges, indicating suitability for surgical intervention via open reduction and internal fixation (ORIF). Preoperative planning, using the AO/ASIF small animal planning guide, enabled precise alignment. The surgical site on the left lateral thigh was aseptically prepared and incised, allowing realignment and stabilization of the proximal and distal fracture fragments using an intramedullary pin (IMP), trimmed to fit the site. A hand drill facilitated accurate positioning of the IMP. Wound closure was completed with a simple continuous subcutaneous suture using 1/0 polyglycolic acid (PGA) and a simple interrupted pattern for skin suturing. Postoperative radiographs confirmed satisfactory alignment and stabilization, providing an optimal environment for bone healing and functional recovery.
