Adding deltoid ligament repair in ankle fracture treatment: Is it necessary? A systematic review.

BACKGROUND

Deltoid ligament injuries are typically caused by supination-external rotation or pronation injury. Numerous ligament reconstruction techniques have been proposed; however, clear indications for operative repair have not yet been well established in the literature.

METHODS

We reviewed primary research articles comparing ORIF treatment for ankle fracture with versus without deltoid ligament repair.

RESULTS

Five studies were identified with a total of 281 patients. 137 patients underwent ORIF with deltoid repair, while 144 patients underwent ORIF without deltoid ligament repair. Clinical, radiographic, and functional outcomes, as well as complications were considered. The average follow-up was 31 months (range, 5-120).

CONCLUSIONS

Current literature does not provide clear indication for repair of the deltoid ligament at the time of ankle fracture repair. There may be some advantages of adding deltoid ligament repair for patients with high fibular fractures or in patients with concomitant syndesmotic fixation.

LEVEL OF CLINICAL EVIDENCE: III.
