Fracture Repair in Cats Using a Conical Coupling Mini 1.9 to 2.5 mm Locking Plate System

Abstract Objective The aim of this study was to retrospectively evaluate the clinical application of the Fixin mini 1.9 to 2.5 system for the treatment of long bone fractures in cats. We proposed that the Fixin mini system would successfully stabilize long bone fractures in cats with a healing time and complication rate similar to those previously reported for feline fractures using other locking bone plate systems. Materials and Methods Medical records and radiographs of cats with long bone fractures stabilized with the Fixin mini 1.9 to 2.5 system were retrospectively reviewed. Signalment, body weight, bone(s) fractured, region of bone fractured, fracture classification, concurrent orthopaedic injuries, complications, time to functional union, if minimally invasive plate osteosynthesis techniques were used, plate size, number of plates, bone graft use and ancillary methods of fixation were recorded. Results Fifty-six fractures in 54 cats were included. Mean time to radiographic union was 8.8 weeks. Complications were recorded in 8 out of 56 fractures. Major complications occurred in 4 of 56 fractures and minor complications occurred in 4 of 56 fractures. Conclusion The Fixin mini 1.9 to 2.5 system had an overall complication rate and time to functional union similar to that of other implant systems used to treat feline long bone fractures and it appears suitable for repair of a wide variety of long bone fracture configurations in cats.

Summary Objectives: To retrospectively evaluate stabilisation of long-bone fractures in cats and small dogs using the Unilock system. Methods: Medical histories and radiographs of consecutive patients with long-bone fractures stabilised with the Unilock system were reviewed. Cases with follow-up radiographs taken at least four weeks postoperatively were included. Signalment of the patient, fracture localisation and type, primary fracture repair or revision surgery, single or double plating, and complications for each patient were noted. Additionally, implant size, number of screws, number of cortices engaged with screws, and number of empty holes across the fracture were evaluated in fractures where a single plate had been applied. Results: Eighteen humeral, 18 radial, 20 fe-moral, and 10 tibial fractures were treated. The Unilock system was used for primary repair in 44 fractures and for revision surgery in 22 fractures. Two plates were applied in 17 fractures, and a single plate was applied in 49 fractures. Follow-up radiographs were taken four to 109 weeks postoperatively. Complications were seen in 12 animals and 13 fractures (19.7%). Fixation failure occurred in seven fractures (10.6%). Cases with a single plate that suffered fixation failure had thinner screws in relation to bone diameter than cases with double plates, and more screws in a main fragment than those without fixation failure. Clinical significance: The Unilock system is a suitable implant for fracture fixation of long bones in cats and small dogs.

Urgent Operation

Results of the treatment of 218 victims with polytrauma were analyzed during the period from 1998 to 2202. There were 127 patients with one and 91 patients with several closed fractures. Authors consider osteosynthesis for closed long bone fractures to be an urgent operation of third term. Osteosynthesis is absolutely indicated to the patients with psychomotor excitation, in cases of the threat for skin perforation by bone fragments and in patients requiring intensive nursing for their life rescue. The choice of operative method depends on polytrauma severity and fracture type. When osteosynthesis is performed by urgent indications in patients with polytrauma the requirements to osteosynthesis stiffness are higher than in isolate injuries, as the rotation displacement, migration and fixator deformity frequently take place in unconscious patients who need constant intensive nursing. In patients with concomitant thorax injury urgent intramedullar osteosynthesis by nail is contraindicated due to the possibility of fat embolism syndrome development. In these patients plate osteosynthesis is preferred. If there are no absolute indications to urgent osteosynthesis this operation could be performed on 3-10 days after trauma using lightly traumatic and invasive methods not waiting for the complete normalization of homeostasis parameters and restoration of soft tissues in the fracture zone. In closed long bone fractures tactics of early osteosynthesis allows to decrease the rate of hypostatic complications and mortality by more than 10% and achieve good functional results.

Embolism Syndrome

Fat embolism syndrome (FES) is a rare multisystem, clinical syndrome occurring in 0.9%–2.2% of long-bone fractures. The severity of FES can vary from subclinical with mild respiratory changes and haematological aberrations to a fulminant state characterised by sudden onset of severe respiratory and neurological impairment. Here we present two patients with cerebral FES secondary to femur fracture. Both patients exhibited profound neurological impairment with varied outcomes. Our cases highlight the importance of a high clinical suspicion of FES in patients with long-bone fractures and neurological deterioration. We recommend early plate osteosynthesis to prevent additional emboli in patients with FES and situational placement of intracranial pressure monitoring. Finally, cerebral FES has low mortality even in a patient with tentorial herniation and fixed, dilated pupils.

Fracture Stability

SummaryLong bone fractures in 20 dogs and five cats were repaired using a stack pinning (multiple intramedullary pins) technique. These cases were evaluated with long-term radiographic and physical examination. Factors including fracture location, age of animal, fracture reduction, and percent of medullary cavity filled by intramedullary pins were noted to assess their effect on postoperative complications. Specifically, distal long bone fractures had a greater tendency to develop complications than did mid-shaft or proximal fractures (p = 0.10). Other factors were not found to significantly increase the potential for fracture related complications. The overall complication rate associated with this method of fracture repair was greater than 50%. External fixators or plates were judged necessary to improve fracture stability at initial or subsequent operations in 44% of cases. Stack pinning was found to be an unreliable method of repair for long bone fractures in this clinical study.
