Abstract
Background
There is no clear consensus on when patients with surgically treated right ankle fractures can return to car driving, or how best to assess their fitness to drive. Through a rigorous driving assessment program consisting of both off-road and on-road tests, we aim to determine if these patients are able to pass a standard driving test, even before weight bearing has been initiated.
Methods
A prospective grant-funded (Supported by AOTrauma Asia Pacific Ref: AOTAP12-17) clinical study was conducted. Patients aged 25–65 years who underwent surgery for right ankle fractures and held a valid motorcar driving license were recruited in a single institution from 2013 to 2015. The surgeon and a specialist occupational therapist assessed the patients at 2, 6 and 12 weeks post-surgery. A Short Musculoskeletal Functional Assessment (SMFA) Questionnaire was administered and the brake reaction time was measured using a driving simulator. Patients who met the minimal criteria were then subjected to a full on-road driving test in a real-world environment with a driving instructor. A follow-up telephone questionnaire was administered at least 6 months after return to driving to determine if patients had returned to driving safely.
Results
A total of 23 patients (8 females, 15 males) were recruited. The mean age was 42.8 (± 12.9) years. There was a significant improvement in the SMFA (p < 0.05) and braking time (p < 0.05) at 6 and 12 weeks post-surgery. Nearly all (91%) patients passed the on-road driving test at 6 weeks, before their fractures had healed or weight bearing was initiated. The questionnaire administered at least 6 months after return to driving revealed that all patients had returned to regular driving safely.
Conclusion
We conclude that patients with isolated, surgically treated right ankle fractures can successfully pass a standard driving test at 6 weeks post-surgery, even before weight bearing has been initiated. We also showed that the ability to drive correlates with improvements in the SMFA scores and braking times.
