Analysis of functional outcome following open reduction and internal fixation of closed bimalleolar fracture in adults

Material and Methods: 30 patients aged between 18-60 years with bimalleolar fractures who fulfilled the inclusion criteria were included in the study. All patients underwent surgical fixation of the fractures. Subjective assesment of persistent pain and swelling was done at 6 weeks post op. The follow-up assessment which consisted of objective (Olerud and Molander Ankle Score) evaluations, were performed at 3 months and 6 months postoperatively.

Results: Out of 30 patients, the commonest injury pattern seen was supination external rotation followed by pronation external rotation. Statistically significant improvement in the mean olerud and molander ankle score from 3month post to 6 month post op at follow up. The mean Olerud and Molander Ankle Score was statistically significant 56.667±16.365 at 3rd month post-op and 78.5±17.722 at 6th month post-op.

Conclusion: Operative treatment for ankle fractures results in good functional outcome postoperatively. Anatomical reduction of the fracture is associated with better functional outcome.
