What is scaphoid fixation?

Scaphoid Fracture Open Reduction and Internal Fixation (ORIF) is a procedure that stabilizes a fractured scaphoid bone with screw fixation. The scaphoid is an important carpal bone of the wrist, which is critical in coordinating motion of the other carpal bones and the radius.

What is percutaneous screw fixation?

Percutaneous pedicle fixation is a specific technique that surgeons can use to implant metal rods and screws that stabilize the spine. This technique may be used during a spinal fusion procedure. Percutaneous pedicle fixation is performed without a traditional large incision.

What is the best treatment for a scaphoid fracture?

There are two general approaches for treatment of a scaphoid fracture: cast immobilization or surgical stabilization. As long as the scaphoid fracture is not displaced (out of position), cast immobilization is a very reasonable treatment. The cast must extend over your thumb to limit the mobility of your thumb.

How long does it take for a scaphoid fracture to heal after surgery?

By using both internal fixation and bone grafting (for nonunions) or internal fixation alone (for acute injuries), most patients recover almost full motion and strength. It may take 6-12 months after the first surgery for this amount of recovery to occur.

Where is the scaphoid bone?

The scaphoid bone is one of the carpal bones on the thumb side of the wrist, just above the radius. The bone is important for both motion and stability in the wrist joint.

What artery supplies the scaphoid?

The major blood supply to the scaphoid is via the radial artery. Seventy to eight percent of the intraosseous vascularity and the entire proximal pole is from branches of the radial artery entering through the dorsal ridge.

What is percutaneous fracture treatment?

Percutaneous skeletal fixation is the surgical procedure of treating fractures by inserting surgical implants through the skin.

Does a broken scaphoid need a cast?

Whether your treatment is surgical or nonsurgical, you may be required to wear a cast or splint for up to 6 months or until your fracture has healed. Unlike most other fractures, scaphoid fractures tend to heal slowly.

How painful is a broken scaphoid?

Scaphoid fractures usually cause pain and swelling in the anatomic snuffbox and on the thumb side of the wrist. The pain may be severe when you move your thumb or wrist, or when you try to pinch or grasp something. Unless your wrist is deformed, it might not be obvious that your scaphoid bone is broken.

Is there a Percutaneous screw fixation for a scaphoid fracture?

(OBQ08.111) Percutaneous screw fixation for non-displaced scaphoid waist fractures has been shown to have which of the following differences compared to closed treatment? (OBQ06.16) A 27-year-old professional cowboy is thrown from a bull during the rodeo and lands on his hand.

Which is an open dorsal approach for a scaphoid waist fracture?

(OBQ09.56) An open dorsal approach for antegrade screw fixation of a nondisplaced scaphoid waist fracture differs in which of the following ways compared to a percutaneous dorsal approach?

When to use Percutaneous Fixation for waist fractures?

Preliminary reduction Percutaneous fixation is largely indicated for undisplaced or minimally displaced fractures of the waist of the scaphoid. Hyperextension and ulnar deviation of the wrist will facilitate any necessary reduction of the fracture.

What are the different types of scaphoid fractures?

Herbert and Fisher Classification (based on fracture stability) Type A Stable, acute fractures Type B Unstable, acute fractures (distal obliqu Type C Delayed union characterized by cyst form Type D Nonunion
