Objectives:
A stainless steel trail plate called the Synthesis Pengo System (S.P.S.) has been developed for human implantation and has also been utilized in veterinary medicine to repair canine diaphyseal fractures. The system includes a trail bar that reduces contact with the bone interface and offers a dynamization mode. However, the size of the plate is considered a major disadvantage. Therefore, this study aimed to propose modifications and evaluate a 3D-printed titanium trail plate for fracture repair in dogs.
Methods:
Three trail plate sizes were designed and labeled as 2.0 mm, 2.7 mm, and 3.0 mm based on the bone screw diameters. The trail plate designs were created using computer-aided design (CAD) software. Subsequently, 3D models of the trail plates were produced from Ti-6Al-4V commercial powder using a direct metal laser sintering (DMLS) process. Only the trail bars and modules were manufactured. The trail plates were tested in 19 dogs, ranging in age from 5 months to 4 years and weighing between 4.8 kg and 23.5 kg. All dogs were crossbred, and the fractures resulted from road traffic accidents. Diaphyseal fractures occurred in the radius and ulna (n=5), femur (n=7), and tibia and fibula (n=7).
Results:
Secondary bone healing was the most common outcome. Complications included plate breakage (n=1), screw loosening (n=1), pin migration (n=1), trail displacement, and bone healing with acceptable malalignment (1)
Conclusions:
The modified 3D-printed titanium trail plate offers a promising option for treating long bone fractures in dogs.
