Interference screw for fixation of FDL transfer in the treatment of adult acquired flat foot deformity stage II.

Introduction: Flexor digitorum longus transfer and medial displacement calcaneal osteotomy have shown favourable results in the treatment of adult acquired flat foot deformity stage 2. Little is known about the resorbable interference screw for tendon fixation and postoperative patient satisfaction though. Moreover possible changes of radiographic parameters at final follow-up, possible implant-associated complications and differences concerning clinical results at final follow-up to other studies using bone tunnel techniques for fixation of the FDL tendon were investigated.
