“…This can be achieved by using an external skeletal fixator that engages the proximal olecranon and extends to the radius and ulna distal to the fracture or by simply stabilizing the ulna alone with a bone plate or interlocking nail. 4,31,32 In toy breed dogs, the shape of the distal ulna precludes stable fixation using a bone plate on the ulna alone, and the small diameter of the medullary canal of the distal ulna does not allow insertion of an interlocking nail. 35 Therefore, we felt that proximal fixation of the olecranon and distal fixation of the radius was the best treatment option.…”

“…4 When the proximal fragment of the radius is too small to achieve adequate fixation, treatment options include use of an interlocking nail or a bone plate on the ulna only, or the use of an external skeletal fixator with fixation pins applied to the olecranon and to the distal radius fragment. 4,31,32 The purpose of this report was to describe the use of a locking plate fixed to the proximal ulna and distal radius for treatment of nonunion of proximal radius and ulna fractures in a toy breed dog.…”

In this case report, we describe an alternative surgical procedure to treat proximal radius and ulnar nonunion in a toy breed dog. A 14-month-old, Maltese cross-breed dog was referred after previous treatment with external and internal fixation had failed, resulting in a nonunion of a fracture of the proximal radius and ulna with the proximal radius fragment too small and friable to be used for fixation. A craniomedial approach was made to debride the radius nonunion site and a second approach to the lateral aspect of the ulna was made. The fracture was realigned and a titanium locking plate was applied in bridging fashion, fixed to the proximal ulnar fragment with three locking screws in the most proximal plate holes, a fourth screw was inserted in the mid-shaft of the distal ulnar fragment and three locking screws were inserted in the distal most holes of the plate through the distal ulna to engage the distal radial fragment. A recombinant bone morphogenetic protein 2 graft was inserted into the radius and ulna fracture sites. The dog had a successful clinical and radiographic outcome with bridging of the defect 4 weeks postoperatively and complete callus formation 8 weeks postoperatively. Implants have undergone dynamization and then removal. Use of a locking plate as an internal fixator achieving fixation of the proximal ulna and distal radius can be considered an option for the treatment of proximal radioulnar nonunions with a small proximal radial fragment.

“…With commonly used ILNs preoperative planning is essential as it is not possible to make adjustments with respect to length, rotation and reposition of bone fragments postoperatively (14). The only preoperative planning required for the TVS is to assure that the minimally required bone diameter for safe bolt insertion is available.…”

“…Osteosynthesis with ILNs is not the most rigid form of fracture fixation, but may have biological, biomechanical, technical and functional advantages (8,17). The main advantages of ILNs are low infection rates (9,10,21), diminished blood loss, a decreased rate of nonunion, as well as shortened hospitalisation times (3,7,9,14,16,23,24). The idea of biological osteosynthesis in diaphyseal fractures, usually performed with the use of ILNs, has changed the anatomic reconstruction into functional reconstruction with restoring the axis, rotation and length.…”

Summary Objective: To describe a newly designed interlocking nail system (Targon® Vet System, TVS) tested in a model of diaphyseal femoral fractures in cats. Material and methods: Introduction of the TVS and presentation of the system components. Evaluation of application range and biomechanical testing of the TVS in cadaver bones under cyclic loading until fatigue failure occurred. The first two test groups compared the influence of implantation and immediate removal of the TVS locking bolts and six holes created by 2.0 mm cortical screws on the stability of feline femora. In the third group the two fixation systems were compared to each other with implants in place in an osteotomy gap model. The failure mode was statistically compared for each group (p < 0.05). Results: Femora after implantation and removal of the bolts of the TVS were significantly stiffer than after implantation and removal of the six 2.0 mm cortical screws. In the osteotomy gap model, femora with the TVS in place failed somewhat later, but not statistically significant, than the opposite femur of the same cat with the 2.0 8-hole DCP in place. Conclusion and clinical relevance: Using this testing method, stability of the TVS seems to be biomechanically comparable to conventional osteosynthesis plate systems. Therefore the TVS may be an encouraging alternative to conventional osteosynthesis systems in diaphyseal fractures, offering several advantages without the need for extensive specialized equipment.

“…Interlocking nails can be a good choice of fracture fixation when indirect reduction and minimally invasive surgery are desired (1). These implants are frequently used for treatment of femoral, humeral and tibial fractures in both human and veterinary surgery and have recently been adapted to fit small bones (2)(3)(4). The traditional interlocking nail consists of a large, solid nail with transverse holes at both extremities, allowing for screws or bolts to be inserted through the nail, effectively anchoring the nail to the bone fragments (5).…”
