Hallux Valgus Correction Using the Metal Screw or the Human Allogeneic Cortical Bone Screw (Shark Screw).
Sponsor: Orthopedic Hospital Vienna Speising
Summary
The goal of this clinical trial is to compare the treatment of Hallux Valgus using the conventional method (metal screw) with the new method (human allogeneic cortical bone screw (Shark Screw®) in adult patients with confirmed Hallux Valgus. The main questions it aims to answer are: Can the new method obtain comparable results as the conventional method in regard to union rate and time to union? Are the number of complications lower with the new method? Participants will be operated either with the metal screw or with the Shark Screw®. The assignment to the groups is randomized.

Hallux Valgus Treatment with Shark Screw®
This is a prospective, randomised study in which hallux valgus is corrected by means of a chevron/kin surgery technique using metal screws or human allogenic cortical bone screws (Shark Screw®, Surgebright, Lichtenberg, Austria). X-rays are taken before the operation at 6 weeks, three, six and twelve months after the operation. The X-ray images provide information on whether bony degeneration has taken place. In addition, the American Orthopaedic Foot \& Ankle Society (AOFAS) hallux score, FFI score, hallux valgus angle (HVA) and intermetatarsal angle (IMA) are determined. These data are collected preoperatively and 4 weeks (HVA and IMA), six and twelve months postoperatively in order to rule out a change in the HVA and IMA and to document the changes in the AOFAS/FFI.
