Abstract
Opening Base Wedge Osteotomy of the First Metatarsal Using the Arthrex Low Profile Plate and Screw System
Highlights
Inc. has introduced a low profile titanium plate with a central spacer to allow accurate and more stable correction of the opening base wedge osteotomy. (Figs. 1,2) the use of the Arthrex Low Profile Plate and Screw SystemTM eliminates the need for a bone graft to hold the metatarsal in the corrected position
Once all screws are placed and the plate secured, the remaining void of the osteotomy should be filled with bone graft. This is usually done with a combination of the bone graft harvested from the medial eminence of the metatarsal head as well as allogenic cancellous bone chips. (Fig. 10 and 11) In hallux abduco valgus with larger intermetatarsal angles, there is a greater chance for compromise of the lateral cortical hinge
The opening base wedge technique was first described by Trethowin in 1923.1 In 1983, Beronio described using the medial eminence of the first metatarsal as a graft for the opening wedge osteotomy.[2]
Summary
Opening Base Wedge Osteotomy of the First Metatarsal Using the Arthrex Low Profile Plate and Screw SystemTM by Mark A. 1,2) the use of the Arthrex Low Profile Plate and Screw SystemTM eliminates the need for a bone graft to hold the metatarsal in the corrected position. Inc. has introduced a low profile titanium plate with a central spacer to allow accurate and more stable correction of the opening base wedge osteotomy. This makes the procedure less cumbersome than it may have been in the past
