What is scaphoid humpback deformity?
Scaphoid humpback deformity consists of volar shortening, angulation of the scaphoid with the apex dorsal, dorsal shift of the distal fragment and DISI deformity (Steinmann and Cooney, 2010). Extension of the proximal pole and flexion of the distal pole will gape the fracture site open on the dorsal side.
What is the clinical significance of the scaphoid?
Clinical significance Fractures of the scaphoid are the most common of the carpal bone injuries, because of its connections with the two rows of carpal bones. The scaphoid can be slow to heal because of the limited circulation to the bone.
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. Skip to Play Button.
What is a humpback deformity?
Humpback deformity of the scaphoid results from volar angulation of the proximal and distal poles of the scaphoid in the setting of scaphoid fracture through the waist 1. The dorsal component forms a ‘humpback’ which can be palpated.
What is a SNAC wrist?
Scaphoid Nonunion Advanced Collapse (SNAC) describes the specific pattern of progressive arthritis of the wrist that results from a chronic scaphoid nonunion.
Which location of the scaphoid is most prone to injury?
A scaphoid fracture is usually described by its location within the bone. Most commonly, the scaphoid breaks in its mid-portion, called the “waist.” Fractures can also occur at both the proximal and distal ends of the bone.
Why is scaphoid most commonly fractured?
Your scaphoid is one of your carpal bones, the collection of bones that makes up your wrist. Scaphoid fractures are almost always caused by catching yourself with outstretched arms after a fall. Car accidents and other traumas can also cause them. You might need surgery to repair your bone.
Can scaphoid fracture cause carpal tunnel syndrome?
Acute carpal tunnel syndrome caused by fracture of the scaphoid and the 5th metacarpal bones. Injury.
Should I get scaphoid surgery?
If your scaphoid is broken at the waist or proximal pole or if pieces of bone are displaced, your doctor may recommend surgery. The goal of surgery is to realign and stabilize the fracture, giving it a better chance to heal.
