Ultrasonically assisted anchoring of biodegradable implants for chevron osteotomies - clinical evaluation of a novel fixation method.

Unlabelled: Reconstructive osteotomies for the treatment of Hallux valgus are among the most prevalent procedures in foot and ankle surgery. The combination of biodegradable materials with an innovative method for fixation by application of ultrasonic energy facilitates a new bonding method for fractures or osteotomies. As clinical experience is still limited, the aim of this study was to assess the safety and performance of the SonicPin system for fixation of Austin/Chevron osteotomies.

Objective: With this joint-preserving procedure impinging and damaged parts of the first metatarsal head and the proximal phalanx are removed. The attachment of the short flexor tendon is preserved. Joint motion will increase and joint function is preserved.
