Immediate mobilisation following corrective osteotomy of distal radius malunions with cancellous graft and volar fixed angle plates.

Abstract

The purpose of the study was to examine the reliability with which a specific technique of corrective osteotomy of malunions of the distal radius combined with early mobilisation could both restore the normal anatomic parameters of the radius and achieve a functional range of motion with good strength. Corrective osteotomy of the distal radius was performed through a volar approach using a fixed angle volar plate and cancellous bone graft from the iliac crest in 19 patients of mean age 50 years with initial malunions with a mean dorsal tilt of 36 degrees and 7 mm of ulnar variance. An immediate mobilisation programme was started. All healed at a mean of less than 12 weeks (including two heavy smoking patients who required repeat cancellous bone grafting to achieve final union) to achieve a total arc of wrist motion around 120 degrees, forearm rotation of 158 degrees and grip strength which was 80% of contralateral. This treatment strategy was judged to be straightforward and effective.
