Static monolateral external fixation for the Rolando fracture: a simple solution for a complex fracture.

INTRODUCTION

Rolando fractures are often difficult to manage because of their inherent instability. We describe a simple technique for the treatment of this fracture using the principle of ligamentotaxis, with a static, two-pin external fixator spanning the trapeziometacarpal joint, and present the results of a single-surgeon case series.

METHODS

Eight consecutive patients (mean age: 32.8 years) with Rolando fractures were treated using a Hoffmann II(®) Micro small bone external fixator using blunt ended 2.0mm half pins, inserted into the trapezium and diaphysis of the first metacarpal. Functional outcome was assessed with the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score at a mean time of 2.7 years following the fracture (range: 4 months-6.0 years). The mean time to frame removal was 28 days.

RESULTS

There were three cases of superficial pin site infection. Follow-up x-rays at four months did not demonstrate significant joint incongruity or malunion in any case. The mean QuickDASH score was 7.95 and all patients returned to their previous levels of activity.

CONCLUSIONS

Although external fixation risks pin site infection, the results of this study support the use of spanning trapeziometacarpal external fixation for Rolando fractures as it reliably gives excellent functional outcomes.
