Blowout fractures result from trauma to the orbital bones. When an object hits the orbital bones (usually the eye brow and upper cheek bone) the force is transmitted to the bones. If the force is great enough, the bones buckle and break. Any large object with force or speed can cause a blowout fracture.
What part of the bony orbit does a blowout fracture affect?
Indirect orbital floor fracture (“blowout fracture”) — This occurs when the bony rim of the eye remains intact, but the paper thin floor of the eye socket cracks or ruptures. This can cause a small hole in the floor of the eye socket that can trap parts of the eye muscles and surrounding structures.
What is the most common type of blowout fracture?
So the medial wall blowout fractures are second most common, whereas superior wall i.e. the roof and lateral wall blowout fractures are uncommon & rare respectively….Orbital blowout fracture.

What nerve is damaged in Galeazzi fracture?
Galeazzi fractures are sometimes associated with wrist drop due to injury to radial nerve, extensor tendons or muscles.
What is the anatomical location of a blowout fracture?
Isolated fractures of the orbital floor or medial wall are often referred to as blowout fractures (BOFs).
How common are blowout fractures?
Pure superior blowout fractures (without associated orbital rim fracture) are uncommon. They are usually seen in patients with pneumatization of the orbital roof 2,4. Fractures may only involve the sinus, the anterior cranial fossa (less common), or both sinus and anterior cranial fossa.
Why is damage blowout fracture especially complicated when involving the inferior or medial portion of the orbit?
Fractures of the orbital floor and the medial orbital wall (blowout fractures) are common midface injuries. Orbital fractures have a distinct trauma mechanism and are complex due to the complex anatomy of the bony and soft tissue structures involved.
What is Holstein fracture?
Description. Holstein–Lewis fracture: simple spiral fracture of the distal third of the shaft of humerus with distal bone fragment displaced and the proximal end deviated toward the radial side with an increased risk of acute radial nerve palsy.
How many types of Galeazzi fractures are there?
Galeazzi Fractures
| OTA classification of radius/ulna | |
|---|---|
| 22-A2.3 | Radius/ulna, diaphyseal, simple fracture of radius with dislocation of DRUJ |
| 22-B2.3 | Radius/ulna, diaphyseal, wedge fracture of radius with dislocation of DRUJ |
| 22-B3.3 | Radius/ulna, diaphyseal, wedge of both bones with dislocation of DRUJ |
Is surgery needed for a blowout fracture?
Surgery will most likely be required to repair the fracture to the orbital floor and release any muscles and/or nerves that may have been compromised as a result of the fracture.
Do spiral fractures require surgery?
Most spiral fractures require surgery and general anesthesia. Less severe cases, where the bone is not fully separated, may be operated on using local anesthesia. If the two ends of the bone are separated then an open reduction surgery will be necessary.
What is a midshaft fracture?
A mid-shaft humerus fracture is a type of broken arm. The humerus is the bone in your upper arm, between your shoulder and elbow. It’s especially strong and is capped with the ball of the ball-and-socket shoulder joint. It also includes the hinge of the elbow joint on the bottom.
What is an orbital blowout fracture?
An orbital blowout fracture is a fracture or break in the small bones that make up your eye. The orbit, or eye socket, is the cavity of the skull that holds the eye. An orbital blowout can occur when an object strikes the orbit with blunt force. This injury is commonly the result of a fist, baseball, or tennis ball that strikes the eye.
How common are superior blowout fractures?
Pure superior blowout fractures (without associated orbital rim fracture) are uncommon. They are usually seen in patients with pneumatization of the orbital roof 2,4. Fractures may only involve the sinus, the anterior cranial fossa (less common), or both sinus and anterior cranial fossa.
What is the pathophysiology of a blowout fracture?
A blowout fracture is caused by a traumatic force applied to the orbital rim or globe and usually results in a sudden increase in intraorbital pressure. The incompressible intraorbital contents are displaced posteriorly, and the traumatic force is transmitted to the thin orbital floor and medial orbital wall, which are the first to fracture.
What is blow out FRAC·Ture?
blow-out frac·ture. A fracture of the floor or medial wall of the orbit, without a fracture of the rim, produced by a blow on the globe with the force being transmitted via the globe to the orbital floor.
