The purpose of this study was to compare the structural characteristics of 2.0-mm polyglycolic acid pins and 2.0-mm Steinmann pins in oblique closing base wedge osteotomies of the first metatarsal bone commonly used to correct metatarsus primus varus. Six pairs of fresh frozen cadaveric first metatarsal bones were osteotomized, fixated with either absorbable or stainless steel 2.0-mm pins, cemented in a specimen-holding jig, and tested with the Bionix Material Testing System. There was no significant difference in the mean ultimate force, ultimate displacement, or structural stiffness when comparing 2.0-mm polyglycolic acid pins and Steinmann pins in this model. The structural characteristics of 2.0-mm absorbable pins were the same as stainless steel pins at the time of initial placement in the oblique closing base wedge osteotomy of the first metatarsal.
