1. Chevron Osteotomy

A) Chevron osteotomy with 2.7mm ActivaScrew™

This version of chevron osteotomy can be fixed with single 2.7mm screw that is passed from dorsal distal to plantar proximal. Implant hole is drilled and tapped through to reach the secondary cortex with screw. Angle of the chevron cut is reduced creating more cortical platform for the screw with longer dorsal arm.

Only light countersunk or overdrilling of the dorsal cortex will be needed because of the small size of the screw head. Screw head and/or protruding distal end can be smoothened after insertion by High Temperature Cautery (B-HTC-1000) if needed.

B) Chevron osteotomy with 2.0mm ActivaPin™ (lengths 30mm and longer)

There are several variations of chevron osteotomy fixation with ActivaPinTM. With transarticular technique pin is inserted from distal plantar to proximal dorsal reinforcing the impaction of the osteotomy. Both ends of the pin can be resected by High Temperature Cautery (B-HTC-1000) to improve stabilization and create compression lock.

C) Chevron osteotomy (optional technique) with 2.0mm ActivaPin™

One optional method is the technique where the pin is driven from proximal medial to distal lateral into the capital fragment without entering the metatarsophalangeal joint.
