Isolated Medial Rectus Entrapment Due to Medial Wall Blowout Fracture A Case Report

Isolated medial rectus fracture with medial rectus entrapment is an extremely rare injury, but can have a delayed presentation. We present a case of traumatic medial rectus entrapment due to medial wall blowout fracture in a teenage boy. The patient presented nearly two weeks after the traumatic event complaining of an inability to adduct his right eye. Physical exam revealed an inability to adduct the affected eye and a CT scan showed a medial orbital wall blowout fracture with isolated medial rectus entrapment. The patient underwent surgical repair with improvement to his extraocular motility. Providers should have a high degree of suspicion for medial rectus entrapment and should refer these patients for immediate surgical repair.
