Objectives: Combined fractures of the distal radius and scaphoid bone are rare. The aim of this study was 1. to present a case series on patients with combined scaphoid and distal radius fractures, and 2. to outline features of this injury which may dictate the management technique.

 

Setting and Design: A retrospective review was performed on 10 patients with  combined fractures of the distal radius and scaphoid. Radial fractures were classified using the Comprehensive AO classification. Scaphoid fractures were classified according to location and displacement of the fracture. Outcome was measured in terms of ROM, pain and radiographic signs of healing.

 

Results: Mean follow-up was 28 months. There was 1 extra-articular radial fracture (type A) and 9 intra-articular fractures (1 type B ; 8 type C). The extra-articular fracture was treated non-operatively in a cast with a good outcome in terms of ROM and radiographic healing. ORIF was performed in all of the intra-articular fractures of the distal radius. Complications included avascular necrosis of the scaphoid (1 patient) and limitation of ROM (2 patients). At follow-up, all the fractures were radiographically healed.

 

Conclusion: In treating combined fractures of the distal radius and scaphoid,  emphasis should be placed on treatment of the radial fracture. Restoration of articular congruity and radial length is the priority and ORIF is indicated in all displaced fractures. External fixation of the radial fracture is not recommended unless the scaphoid fracture is fixed internally. Undisplaced fractures in both locations can be treated nonoperatively with good outcomes.
