Biofix fixation techniques and results in foot surgery

Biofix absorbable rods have been used for internal fixation for 10 years, and one of its most utilized applications has been osteotomies of the first metatarsal. This study evaluates 59 procedures on 49 patients completed over a 3-year period, using the 2.0-mm. Biofix rods. The transarticular technique for the fixation of osteotomies in the 1st and 5th metatarsals and the intramedullary technique used for digital fusions are described. All of the patients were followed for a minimum of 3 months, but most for > 1 year, and all of the procedures were evaluated for failure of fixation, osteolytic bone changes, sterile sinus development, and infection. There were no failures of fixation and no infections in this series. Patients (22.4%) developed radiographic osteolytic changes, and 4.1% of the patients developed sterile sinus discharge. However, these had no effect on the procedures' success or outcomes. An introduction to future application of the technology using Biofix screws and plates is made with a pantalar fusion case as an example.
