2) Proximal osteotomy of the First Metatarsal with 2.7mm - 4.5mm ActivaScrew™

 

Wedge resection is done into the proximal metaphysis. Medial cortical hinge of bone is kept intact at the apex and one screw is inserted from the distal medial to proximal lateral.

 

Modified version with oblique osteotomy can also be used. The osteotomy is angled from proximal medial to distal lateral with the apex medial and base lateral. Besides reducing the intermetatarsal angle it can be used to shorten or lengthen and dorsiflex or plantarflex the metatarsal. If medial cortical hinge is resected to allow length modification osteotomy needs to be fixed with two 2.7mm or 3.5mm screws or with one screw and one pin combination.

With rigid fixation with 4.5mm screw weight bearing can be allowed to the lateral side with out plaster cast or extra immobilization.
