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.

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.

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.

A Prospective Study

<p class="abstract"><strong>Background:</strong> Tibia is most exposed bone in the body and vulnerable to trauma and therefore its fractures are common among the long bone fractures. Tibia is the common site of non-union in long bone fractures. Management of non-union in long bone fractures is a challenging problem for orthopedic surgeons. When the defect is more than 4 cm then it needs bone transport.</p><p class="abstract"><strong>Methods:</strong> Materials of this study comprised 20 cases of nonunions of tibia treated over 2½ years period from June 2006 to December 2009 in the Department of Orthopedics at Narayana Medical College, Nellore, Andhra Pradesh. This was a prospective study of nonunions of tibia treated by Ilizarov ring external fixators and incidental surgery.<strong></strong></p><p class="abstract"><strong>Results:</strong> Out of 20 tibial non-unions, in 15 patients the fixator has been removed. In 4 patients the fracture had united but the fixators are in situ and they are in consolidation phase and the remaining 1 patient is in various stage of follow up. The results of the 15 patients in whom the fixators have been removed are studied. The hospitalization time from 15 days to 120 days. The average hospital duration is 44.04 days. The total time ranged from 4 months to 15 months. Average time is 9.25 months.</p><p class="abstract"><strong>Conclusions:</strong> From this study we conclude that Ilizarov external fixator is a reliable, versatile and effective treatment for the treatment of tibia nonunion fractures.</p>
