Stabilization with internal plate fixation following fracture of both bones of the forearm restores nearly normal anatomy and motion. However, a moderate reduction in the strength of the forearm, the wrist, and grip should be expected following this injury. Perceived disability as measured with the DASH and SF-36 questionnaires is determined by pain more than by objective physical impairment.
Volar wedge osteotomy and angle stable volar plating is now considered a standard approach for correction of distal radius malunion. In previous descriptions of the technique, soft tissue release has been performed with periosteal incision in line with the bony osteotomy. We present a technique whereby the dorsal periosteum is incised more proximally creating a dorsal vascularized periosteal "curtain." Our technique has several advantages including systematic release of restraining soft tissues to allow better distraction and reduction of the malunion; a dorsal periosteal curtain of vascular tissue with which to contain bone graft, protect extensor tendons and expedite healing; and better access to locally available bone graft. The previously described rotation-advancement of pronator quadratus is also used for plate coverage. We have found this technique straightforward to execute and teach, and useful in mitigating against some of the potential risks of the standard technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
