INTRODUCTION: Flexor digitorum longus transfer and medial displacement calcaneal osteotomy have shown favourable results in the treatment of adult acquired flat @entity5109 stage 2. Little is known about the resorbable interference screw for tendon fixation and postoperative @entity1 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. MATERIALS AND METHODS: 21 feet in 21 @entity1 with a mean age of 51  years were evaluated pre- and postoperatively after a standardised operative procedure using MDCO and FDL transfer with interference screw fixation. @entity1 were evaluated with the American Orthopaedic Foot and Ankle Society Hindfoot Score and the Visual Analogue Scale at an average follow-up of 20  months. Hindfoot radiographic parameters were evaluated according to AOFAS guidelines. For statistical analysis SPSS v.15.0.1 was used. RESULTS: The average AOFAS Score (from 42 to 95 points) and VAS (from 0.5 to 8 points) both increased significantly (p  <  0.001 each) from preoperative to final follow-up as well as the hindfoot valgus (from 10 to 4 degrees (p  =  0.005)) and the lateral talo-first metatarsal angle (from 13.6 preoperative to 5.2   at follow-up). 88 percent of @entity1 evaluated the postoperative result with "very good" or "good". Implant-associated complications could not be detected. CONCLUSION: We conclude that interference screw fixation for FDL transfer is a safe and promising operative technique, allowing a smaller skin incision without disrupting the normal interconnections at the knot of Henry, while achieving very high @entity1 satisfaction and improving postoperative function as well as relieving @entity158 . This method is technically easy to perform, has a low complication risk and we, therefore, recommend this fixation technique in @entity1 with adult acquired @entity85 stage 2.
