When considering the contents of the anatomical snuffbox, it is helpful to divide the structures into two groups: those that lie superficial to the extensor retinaculum and the tendons of the outcropping muscles, and those that lie deep to these structures. Fractures with even small amounts of displacement are prone to nonunion, and operative treatment is recommended.19 Splinting and referral are indicated. Anatomical-snuff-box.jpeg 160 199; 5 KB. 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. Unless the activity is prolonged or chronic, results of the sensory examination are normal and numbness will resolve within a few hours after stopping the activity. Examination reveals scapular winging and weakness with forward elevation of the arm. Symptoms of radial tunnel syndrome are almost identical to those of tennis elbow (i.e., lateral epicondylitis), and distinguishing the two can be difficult because physical examination maneuvers that aggravate radial tunnel syndrome may also be positive in patients with tennis elbow (e.g., supination against resistance with the elbow and wrist extended, and resisted extension of the middle finger).14 A differentiating factor is the point of maximal tenderness.

This information is provided as an educational service and is not intended to serve as medical advice. Mechanisms of nerve injury include direct pressure, repetitive microtrauma, and stretch- or compression-induced ischemia. 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. This type of nerve injury occurs with other activities involving prolonged pressure on the volar wrist (e.g., jackhammer use).
