Isolated inferior rectus muscle rupture after blunt orbital trauma

Complete transection of the inferior rectus following blunt trauma: a case report

This report describes a rare case of complete transection of the inferior rectus resulting from blunt trauma to the orbit. Only eight other cases were identified in the literature. Computed tomography scans should be examined carefully for potential extraocular muscle injury.

Isolated Inferior Rectus Muscle Rupture and Surgical Repair: A Case Report

We describe the case of a 37-year-old male who experienced an isolated rupture of the inferior rectus muscle in the right eye following a facial impact from a wire. Upon examination, a minor restriction in downward gaze was observed. An orbital computed tomography scan confirmed the integrity of the globe and the absence of an orbital fracture-subsequent surgical exploration involved identifying and suturing together the distal and proximal ends of the affected muscle. Postoperatively, normal eye movements were restored.

Traumatic rupture of the inferior rectus muscle: case report and review of the literature

Traumatic inferior rectus muscle rupture secondary to blunt injury in the absence of associated orbital or ocular fractures or injury is rarely encountered, and there are limited published reports on subsequent surgical repair. We present the case of a 74-year-old man with complete inferior rectus transection following a fall with facial strike. A computed tomography scan of the face was unremarkable. Surgical exploration and repair of the muscle was performed by hooking the inferior oblique muscle to identify the inferior rectus muscle. Subsequent strabismus surgery was performed for residual binocular diplopia, resulting in excellent anatomic and visual outcomes and postoperative ocular alignment.

Inferior Oblique Entrapment After Orbital Fracture With Transection and Repair

Extraocular muscle (EOM) entrapment with resulting reduction in motility and diplopia is a known complication of orbital fractures. Less commonly, transection of the EOMs due to trauma, iatrogenic injury, or intentional myotomy may lead to persistent diplopia. The inferior oblique (IO) is often encountered during orbital surgery along the medial wall and floor, and may be disinserted to aid in visualization. The authors present a case of IO entrapment which occurred during zygomaticomaxillary fracture reduction. Intraoperatively, an IO transection was performed and the muscle was reattached within the orbit. Postoperatively, the patient did not develop diplopia or motility disruption. This technique may provide a useful solution to an unusual problem during orbital fracture repair.

Complete Inferior Rectus Transection Following Blunt Trauma: A Case Report and Novel Approach to Surgical Repair

Inferior rectus avulsion following blunt trauma is rare, with even fewer reported cases of complete transection. The authors report a case of orbital floor fracture and inferior rectus muscle transection without herniation following blunt orbital trauma. This case first highlights the difficulty in diagnosing complete inferior rectus muscle transection clinically and with imaging and second that an acceptable functional outcome can be achieved by a novel surgical repair approach utilizing contiguous orbital anatomical relations of the inferior oblique and inferior rectus muscles.
