A scaphoid fracture is a break of the scaphoid bone in the wrist. Scaphoid fractures are most commonly caused by a fall on an outstretched hand. The fracture may be preventable by using wrist guards during certain activities.
People with scaphoid fractures generally have snuff box tenderness. Focal tenderness is usually present in one of three places: Avascular necrosis AVN is a common complication of a scaphoid fracture.
Since the scaphoid blood supply comes from two different fractrue branches of the radial artery, fractures can limit access to blood supply.

Non union can also occur from undiagnosed or undertreated scaphoid fractures. Arterial flow to the scaphoid enters via the distal pole and travels to the proximal pole. This blood supply is tenuous, increasing the risk of nonunion, particularly with fractures at the wrist and proximal end. Symptoms may include aching in the wrist, decreased range of motion of the wrist, and pain during activities such as lifting or gripping.
If x-ray results show arthritis due to an old acaphoide, the treatment plan will first focus on treating the arthritis through anti-inflammatory medications and wearing a splint when an individual feels pain in the wrist.
If these treatments do not help the symptoms of arthritis, steroid injections to the wrist may help alleviate pain.
Should these treatments not work, surgery may be required. Fractures of scaphoid can occur either with direct axial compression or with hyperextension of the wrist, such as a fall on the palm on an outstretched hand FOOSH. Using the Herbert classification system, there are three main types of scaphoid fractures.
Scaphoid fractures are often diagnosed by PA and fracturee X-rays. However, not all fractures are apparent initially. Even then a fracture may not be apparent. A CT Scan can then be used to evaluate the scaphoid with greater resolution. Radiolucency around a 12 days old scaphoid fracture that was initially barely visible.
Treatment of scaphoid fractures is guided by the location in the bone of the fracture proximal, waist, distaldisplacement or instability of the fracture, and patient tolerance for cast immobilization. Non displaced or minimally displaced waist and distal fractures have a high rate of union with closed cast management.
The choice of short arm, short arm thumb spica or long arm cast is debated in the medical literature and no clear consensus or proof of the benefit of one type of casting or another has been shown; although it is generally accepted to use a short arm or short arm thumb spica for non displaced fractures. Fractures that are more proximal take longer to heal. It is expected the distal third will heal in 6 to 8 weeks, the middle third will take 8—12 weeks, and the proximal third will take 12—24 weeks.
Surgery is necessary at this point to mechanically mend the bone together. Percutaneous screw fixation is recommended over a wide surgical approach as this method preserves the palmar ligament complex and local vasculature, and helps avoid postoperative complications.
This surgery includes screwing the scaphoid bone back together at the most perpendicular angle possible to promote quicker and stronger healing of the bone. Fractures of the scaphoid are common in young males. These are also called navicular fractures the scaphoid also being called the carpal navicularalthough this can be confused with the navicular bone in the foot.
