Original publication title: Osteomyelitis and neoplasia associated with use of the Jonas intramedullary splint in small animals.
Plain-English summary
A 5-year-old dog had a fracture repaired using a special splint called the Jonas intramedullary splint. Unfortunately, after some time, the dog developed a serious bone infection (osteomyelitis) and a tumor near the splint. The splint was found to be corroded, which likely contributed to these problems. Due to these risks, veterinarians now recommend against using this type of splint for fixing fractures in small animals.

Abstract
In 11 cases (10 dogs, 1 cat) in which fractures were repaired with the Jonas intramedullary splint, osteomyelitis developed in 6 and tumors developed in 5. In each case, the tumor originated in close proximity to the splint, at the midshaft of the femur or radius. All implants had been in place for 6 months to 6 years in the case of tumors, and for 4 months to 6 years in the cases involving osteomyelitis. Corrosion was evident in all retrieved implants. The corrosion was attributed to fabrication of the devices with a corrosion-susceptible stainless steel, AISI type 304. The corrosion was believed to have been accelerated by stress effect due to differences in cold work of the sleeve and pin and the difference in composition between the sleeve and spring of the splint. It was concluded that fixation of fractures in small animals should not be performed with the Jonas intramedullary splint.
