The most common nerve entrapment injury is carpal tunnel syndrome, which has an estimated prevalence of 3 percent in the general population and 5 to 15 percent in the industrial setting.1 Given the potential for longstanding impairment associated with nerve injuries, it is important for the primary care physician to be familiar with their presentation, diagnosis, and management. The scaphoid bone is one of the carpal bones on the thumb side of the wrist, just above the radius. Results of the Tinel sign and Phalen maneuver at the wrist should be negative in patients with pronator syndrome.13. When pain or weakness is refractory to conservative therapy, further evaluation (e.g., magnetic resonance imaging, electrodiagnostic testing) or surgical referral should be considered. On the thumb side of the wrist there is a little triangular . The snuff mull is a specific type of snuff box which was fashioned out of horn, with a metal lid; they originated in Scotland in the early 19th century. All Rights Reserved.

Radial styloid process can be palpated proximally and the base of the first metacarpal can be palpated distally in the snuff box. Specifics of conservative therapy and indications for surgical referral are shown in Table 6.13,15,2546, Systematic reviews of carpal tunnel syndrome have found short-term benefit from local corticosteroid injection, splinting, oral corticosteroids, ultrasound, yoga, and carpal bone mobilization.29 Symptom relief from local injection has not been shown to last longer than one month, and there is no demonstrated benefit from a second injection.30 Clinical outcome from local corticosteroid injection is similar to that from splinting combined with anti-inflammatory medication.29 Vitamin B6, ergonomic keyboards, diuretics, and nonsteroidal anti-inflammatory drugs have not been shown to be beneficial.29,30 Patient characteristics that predict a poor response to nonsurgical therapy include age older than 50 years, symptom duration longer than 10 months, history of trigger digit, constant paresthesias, and Phalen maneuver that is positive in less than 30 seconds.47 Surgical treatment likely has better outcomes than splinting, but it is unclear if surgical treatment is better than corticosteroid injection.48. This triangular depression is defined by the extensor and abductors of the thumb, and is easily visible when the wrist is partially ulnar deviated and the thumb abducted and extended. The anatomical snuff box or snuffbox or foveola radialis is a triangular deepening on the radial, dorsal aspect of the handat the level of the carpal bones, specifically, the scaphoid and trapezium bones forming the floor.

Starring as fictionalized versions of themselves, Berry . The radial artery crosses the floor of the anatomical snuffbox in an oblique manner. Screw fixation may speed recovery to pre-injury activities; referral for surgery may be indicated, depending on the needs of the patient.18 As the fracture line moves proximally, there is more risk of displacement and nonunion; therefore, it would be appropriate to refer these patients for orthopedic consultation. To gain these skills, the student learns best with good anatomical models or a well-dissected cadaver, at the laboratory bench, guided and instructed by experienced teachers, and inspired toward self-directed, diligent reading.
