Proximal Supination Osteotomy of the First Metatarsal for Hallux Valgus

Abstract:
Postoperative recurrence of hallux valgus is a relatively common complication and is associated with unsatisfactory surgical outcomes. Risk factors for postoperative recurrence include a round lateral edge of the first metatarsal head (a positive round sign) and incomplete reduction of the sesamoids. These risk factors may relate to residual pronation of the first metatarsal following surgery. A novel technique of a proximal supination osteotomy, in which varus and pronation of the first metatarsal can be corrected simultaneously, can achieve significant correction in moderate or severe hallux valgus deformity and a low rate of hallux valgus recurrence.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
