Abstract

Background
The purpose of this study was to classify the possible indications for a combined approach to distal radius fractures (DRFs) by investigating surgical outcomes of patients treated according to our treatment algorithm.
Methods
A combined approach was performed in 32 patients. Patients who were thought to need a combined approach were classified into three types according to the combined injuries associated with loss of volar cortical buttresses in DRFs. The classifications included the following: type 1, free intra-articular fragments; type 2, distally migrated dorsal fragments located beyond the wrist joint; and type 3, centrally impacted articular fragments and displaced dorsal fragments, not reduced by indirect methods.
Results
Seven patients had type 1 fractures treated with volar plates and excision of the intra-articular fragments. Fourteen patients had type 2 fractures: 12 were treated with volar plates and excision of dorsal fragments, and 2 with relatively large unstable dorsal fragments were treated with combined volar and dorsal plates. The remaining 11 patients had type 3 fractures treated with combined volar and dorsal plates. At the latest follow-up, the radiographs revealed an average of 16.9° of radial inclination, an average of 4.2° of volar tilt, and an average of 7.5 mm of radial height. According to the Garland and Werley scores, the functional results were excellent for 3 patients, good for 25, and fair for 4.
Conclusions
The classification system indicated when an additional dorsal approach was needed in unstable DRFs, and it may establish useful guidelines for appropriate surgical decision-making.
