The anatomical snuffbox (also known as the radial fossa), is a triangular depression found on the lateral aspect of the dorsum of the hand. All of these modalities have advantages and disadvantages when evaluating patients for potential scaphoid fracture. The presence of any motor symptoms is more likely related to injury of the posterior interosseus nerve, which supplies the extensor muscles of the hand. The radial artery crosses the floor of the anatomical snuffbox in an oblique manner. The scaphoid bone is one of the carpal bones on the thumb side of the wrist, just above the radius. medial: tendons of the extensor pollicis longus, and more laterally abductor pollicis longus, tendons of the extensor carpi radialis longus and brevis, base of 1st metacarpal can be palpated distally and the radial styloid process can be palpated proximally. All material on this website is protected by copyright. Injury of the ulnar nerve at the wrist is common in cyclists because the ulnar nerve gets compressed against the handlebar during cycling, resulting in cyclist's palsy.

The classic hallmark of anatomic snuffbox tenderness on examination is a highly sensitive (90 percent) indication of scaphoid fracture, but it is nonspecific (specificity, 40 percent).5 For example, a false-positive result can occur when the radial nerve sensory branch, which passes through the snuffbox, is pressed and causes pain. There would be atrophy of the thenar muscles. -Glosbe"anatomical snuff box" Bone stimulator. When pain or weakness is refractory to conservative therapy, further evaluation (e.g., magnetic resonance imaging, electrodiagnostic testing) or surgical referral should be considered.

MRI is rarely needed for initial evaluation of a typical nerve injury, although it may be helpful for specific nerves (Table 5).18, Chronic nerve injury can lead to denervation changes in muscle. Forearm pain that is exacerbated by repetitive forearm pronation is the presenting symptom of radial tunnel syndrome, which involves injury to the superficial branch of the radial nerve. For some fractures, your doctor may use a tiny camera called an "arthroscope" to aid in the reduction.
