Summary

When facing an anterior spinal tuberosity fracture, attention should be given to the meniscal lesions especially the anterior root of lateral meniscus due to is proximity.

ePosters will be available shortly before Congress

Abstract

Introduction

Anterior spinal tuberosity has a very close attachment to the ACL and the anterior root of lateral meniscus. Concomitant lesion of these 3 components is anatomically possible and can be evaluated by arthroscopy. The aim of our work is to describe this lesion we found in three patients.

Methods

This was a descriptive and retrospective study about three patients in which we found this pattern of injury. We described the CT scan finding, the surgery technique, and functional results.

Results

We had 3 patients who had fractures of anterior spinal tuberosity. CT scan showed type 3A of Meyers and McKeever fracture. Arthroscopy confirmed the diagnosis and showed an associated lesion with the anterior root of lateral meniscus. All the patients had reattachment of the spinal tuberosity with k-wires and cerclage which were removed within 45 days. On the last follow-up, they had no knee stiffness and satisfactory functional results.

Discussion

Anterior root of lateral meniscus is closely attached to the anterior spinal tuberosity and the ACL. Fractures of anterior spinal tuberosity are equivalent to ACL rupture. When associated to desinsertion of anterior root of lateral meniscus, it will disrupt the anatomy and biomechanics of the meniscus. Reattachment of the spinal tuberosity allows also the reattachment of the meniscal root. This lesion is scarce in the literature.

Conclusion

When facing an anterior spinal tuberosity fracture, attention should be given to the meniscal lesions especially the anterior root of lateral meniscus due to is proximity.
