The Use of Tension Band Wire For Treatment of Dorsal Acetabulum Fracture in an Accidental Cat

Case Description- A mature female domestic short hair cat referred with accident history and left carrying-leg lameness. Clinical Findings- Clinical examination showed pain, crepitus and swelling in proximal part of femur and pelvic cavity. To detect, types and location of probably fracture, orthogonal views (lateral and ventrodorsal) were took. Fracture of dorsal aspect of acetabulum without hip dislocationwas assessed by radigraphical assessment. Treatment and Outcome- Open approach and internal fixation indicated for this instable fracture. Anesthesia inducedusing ketamine and diazepam and anesthesia maintenancewas achieved using ketamine.Cephazolin administrated 15 min preoperatively.Craniodorsal and caudodorsalaspects of the hip joint were exposed by Osteotomy of the greater trochanter and gemelli muscle tenotomyto access to caudal part of acetabulum.The dorsal side of acetabulum was used for tension band fixation. Two Kirschner wire crosses the fracture line to prevent shearing motion at the fracture surfaces and tension band was executed. Finally, Rear legs hobbled to restrict abduction until healing was progressed. Tramadol and Ketoprofen administrated for 3 days to relief pain.Radiographical and return to activity assessment 60 days after surgery showed perfect callus and maturation and appropriate quality of activity Clinical Relevance- Fractures of pelvis are relatively common and in many veterinary practices they constitute 20% to 30% of all fractures. Pelvic fractures rarely are open or compound. Tension band wire fixation can be used only on interlocking, stable two-piece fractures. Simply compressing the fracture will not prevent this type of motion. This type of fixation is not as stable as a plate or lag screw and is best reserved for small breeds of dog and cats
