Hallux valgus according to Austin / Chevron

Case Study & Literature on Shark Screw®

The following case documentation shows the pre- and postoperative course of a hallux valgus correction according to Austin / Chevron. The patient was treated with a screw made of human bone (Shark Screw®). Brcic e. al. showed in 2021 that Shark Screw® is colonized by cells within a few months and, like other allografts, remodels into its own bone.1

Case study hallux valgus after Austin / Chevron:

The intermetatarsal angle is well below 20° in the loaded foot, so the Austin / Chevron subcapital metatarsal osteotomy is used.

The patient complained of persistent pain before hallux valgus surgery. These could be permanently gelid by the hallux surgery. Since Shark Screw® is made of human donor bone (allograft), the patient bears no risk of metal removal after Austin / Chevron hallux valgus surgery.2

“As a private physician, it is important to me that I can provide my patients with the best possible, safe and innovative care, and I am able to do this excellently with Shark Screw®. I save my patients the risk of a second operation for metal removal, which is important to me and my patients.”
