bone block procedure
a 20 × 15 × 3 mm3 bone block was cut from the lateral malleolus, rotated backwards 45°, and sutured back to the periosteum of the lateral malleolus using non-absorbable sutures.
Reattachment of the superior peroneal retinaculum
two suture anchors (Mini Quickanchor,DePuy Mitek) were inserted into the postero-lateral ridge of the lateral malleolus without damaging the cartilaginous ridge, after which the SPR was reattached to the lateral malleolus with the anchored suture. The inner layer of the false pouch was incised, and the outer layer (periosteum) was sutured with the SPR in a pants-over-vest style.
