Dec 20, 2023 · A trapdoor fracture is a fracture of the orbital floor where the inferiorly displaced blowout fracture recoils back to its original position and potentially entraps contents of the orbit. It is seen in children and young adults due to the elasticity of the orbital floor.
A fracture in this location leads either to a “trap door” displacement of the orbital floor, or, if a second fracture is present at the junction of the floor and medial wall, to a completely depressed, separate bony fragment. These deformities are best appreciated on coronal images.
Apr 15, 2021 · In trap door blowout fractures, the injury is generally less severe. Furthermore, the entrapment in adults usually involves the perimuscular tissue with or without a small part of the muscle. This explains the full recovery of all patients in our series.

Dec 20, 2023 · Orbital blow-out fractures are usually the result of a direct blow to the orbit, which causes a sudden increase in intraorbital pressure. Decompression then occurs by fracture of one or more of the bounding walls of the orbit.
They are characterized by double vision, sunken ocular globes, and loss of sensation of the cheek and upper gums from infraorbital nerve injury. The two broad categories of blowout fractures are open door and trapdoor fractures.
May 1, 2001 · Key concepts. High-speed doors boost productivity, while helping isolate specific plant areas. Quicker forklift travel and faster-acting doors create safety concerns. Industrial door accidents fall into four categories: entrapment, downward impact, lateral impact, and secondary impact. It happens time-after-time in plants across the country.
