More recently, the concern regarding the adverse effects of metal implants may provide further grounds for using bioabsorbable rather than metal fixation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This is a prospective study of 383 consecutive patients (439 feet) who underwent a chevron osteotomy to correct a hallux valgus deformity performed between 2005 and 2010. In the study group of 251 patients (285 feet), the distal metatarsal osteotomy was fixed with a bioabsorbable pin made of poly-L-lactide and poly-DL-lactide (70:30 ratio). In the control group of 132 patients (154 feet), the osteotomy was fixed with a metal screw. The average follow-up was 27 months for the study group and 31 months for the control group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>We observed statistically significant improvements in the mean intermetatarsal angle of 6.1 \u00b1 2.7 degrees in the study group and 5.2 \u00b1 1.6 degrees in the control group ( P &lt; .001) and in the mean hallux valgus angle of 14.8 \u00b1 4.7 degrees and 15.5 \u00b1 3.7 degrees, respectively ( P &lt; .001). The mean \u00b1 SD improvement on the American Orthopaedic Foot and Ankle Society 100-point scale was 45 \u00b1 11 points for the study group and 49 \u00b1 15 points for the control ( P &lt; .001).
