title: Granuloma formation after chevron osteotomy fixation with absorbable copolymer pin: a case report.
abstract: After fixation of a chevron osteotomy for hallux valgus of the left foot with a bioabsorbable copolymer, a delayed onset of pain at the surgical site developed. Magnetic resonance imaging showed a cystic lesion that was unresponsive to conservative treatment. Surgical excision determined the lesion to be a giant-cell granuloma formed as a foreign body response to the degrading copolymer.
