Corrective osteotomy for malunited fractures of the distal radius: a follow-up study

Patients with malunited fractures of the distal radius often complain of
weakness, pain, and reduced movement in the wrist and forearm. Corrective
osteotomy may improve the alignment of the distal radius in relation to the
carpus and the distal ulna. Restoration of the anatomical variables improves
the biomechanics of the wrist, resulting in improved grip strength, movement of
the wrist and forearm, and reduced pain. Several studies of acute distal radius
fractures have shown that the radiological result is related to the clinical
outcome, and that union in malalignment leads to a poorer outcome. The aims of
our study are to evaluate the degree of anatomical correction and the
functional outcome after corrective osteotomy of malunited distal radius
fractures. We also want to compare the functional outcome of the osteotomised
wrist with the function of the uninjured wrist.

The aim of this study is to evaluate the results of corrective osteotomy for
distal radius malunion at our institution. We want to compare the pre-operative
and post-operative CT scan-based three dimensional reconstructions for the
comparison between the injured wrist and uninjured wrist. We hope to gain
valuable anatomical information and to create a basis for further research in
studies on various wrist pathology and surgical techniques.

A retrospective observational follow-up study. Anatomical study.

The radiation exposure of scans is estimated to be 0,6 mSv for each
participant. This is comparable to 12-14 weeks background exposure to the
natural radiation in The Netherlands.
