Poly- l-lactic acid rod fixation results in foot surgery

Abstract

The purpose of this study was to evaluate the effectiveness and possible complications of polylactic absorbable devices in surgical procedures involving fixation of the foot. This was a prospective study in which biodegradable rods of poly-L-lactide were used in the fixation of 41 metatarsal osteotomies and digital arthrodeses and one midtarsal fusion in 23 patients. The follow-up time ranged from 6 months to 23 months. Ages ranged from 18 to 70 years with a mean age of 42 years. Clinical and radiographic examination was scheduled for each patient postoperatively at 1 week, 3 weeks, 6 weeks, 3 months, 6 months, 1 year, and 2 years. The gender distribution was 18 female and 5 males. Two patients who had three procedures were lost to follow-up. All of the procedures were evaluated for failure of fixation, radiographic osteolysis, foreign-body reaction, sinus formation, and infection. We noted one failure of fixation and two complications unrelated to the type of fixation. There were no foreign-body reactions, sinus formulations, or infections. We conclude that the poly-L-lactic acid rod is a viable method of fixation for these procedures.
