Initial symptoms are mild, and the injury may be disregarded as a simple sprain. Specific history features are important, such as the type of activity that aggravates symptoms and the temporal relation of symptoms to activity (e.g., is there pain in the shoulder and neck every time the patient is hammering a nail, or just when hammering nails overhead?). The pain, which often is mild, is worsened by gripping or squeezing. 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. In the anatomical snuffbox, the radial artery is closely related (<2mm) with the superficial branch of radial nerve near the styloid process of radius in 48%, while in 24% the radial artery is closely related to the lateral cutaneous nerve of forearm.
