Eckert and Davis Grade 3 Superior Peroneal Retinaculum Injury: Treated by Endoscopic Peroneal Retinaculum Reconstruction and Complicated by Malposition of the Suture Anchors.

INTRODUCTION: Eckert and Davis grade 3 superior peroneal retinaculum injury is rare and the optimal treatment is not yet determined.

CASE REPORT: A 57 year-old lady sprained her left ankle resulting in grade 3 injury of the superior peroneal retinaculum and was treated by endoscopic retinaculum reconstruction. The fracture healed and the peroneal tendons were stabilized. However, it was complicated by protusion of the suture anchors into the posterolateral ankle gutter. The implants were successfully removed endoscopically.

CONCLUSION: Proper selection of the size and dimension of the suture anchor and preoperative planning with computed tomogram is important for usage of suture anchors in the lateral malleolus.
