Abstract

Study Design: Case reports
Purpose: To demonstrate surgical management of traumatic inferior rectus avulsion
Methods: We present 2 cases of isolated avulsion of inferior rectus in the setting of blunt trauma but without an orbital fracture and its surgical management
Results: In both cases, there was no evidence of orbital floor fracture. The proximal end of the muscle was found intact while the avulsion had occurred at the belly. Using careful dissection of tenon’s capsule and using inferior oblique as a guide, the inferior rectus was found and attached to sclera. In one of the cases, the muscle stump at insertion was found not viable and hence resected. Post-operatively, diplopia decreased to a significant extent in both patients with good cosmetic alignment.
Conclusion: Avulsion of recti can be challenging especially in the setting of an intact orbit. A carefully planned approach with thorough, patient and meticulous dissection can aide in repairing and restoring these muscles.
