Despite the frequency with which this area is used, there . The borders are the extensor pollicis longus posteriorly, extensor pollicis brevis and abductor pollicis longus anteriorly and the radial stylus process proximally. Gross anatomy Boundaries. Compression can be from an external or internal source. Easy. The scaphoid has a unique blood supply, which runsdistal to proximal. A more recent article on peripheral nerve entrapment and injury in the upper extremity is available.

Treatment for a scaphoid fracture can range from casting to surgery, depending on the fracture's severity and location on the bone. When present, motor findings are weak digit abduction, weak thumb abduction, and weak thumb-index finger pinch. [1], The three muscles acting on the thumb (APL, EPB, and EPL) are deep to the superficial extensors and emerge (crop out) from a furrow in the lateral part of the forearm that divides the extensors. Any maneuver that causes these tendons to activate (ie extending the thumb against resistance) causes pain along the lateral side of the wrist and forearm. Reduction.

If localized pain is reported in the anatomical snuffbox, afracture of the scaphoidis the most likely cause. A Cochrane review14 of the data found that bone scintigraphy was a cost-effective and accurate method for assessing occult scaphoid fractures compared with repeat plain radiography. In a case where there is localized tenderness within the snuffbox, knowledge of wrist anatomy leads to the speedy conclusion that the fracture is likely to be of the scaphoid. Reproduced from JF Sarwark, ed: Essentials of Musculoskeletal Care, ed 4. Nondisplaced proximal, medial, and displaced fractures warrant referral to an orthopedic subspecialist. Electrodiagnostic testing can be useful and quantitates severity of entrapment, although false negatives and false positives may occur.16,17.

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. Whether your treatment is surgical or nonsurgical, you may be required to wear a cast or splint for up to 6 months or until your fracture has healed.

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. The snuff box is visible as a hollow on the lateral aspect of the wrist when the thumb is extended fully; this draws the APL, EPB, and EPL tendons up and produces a concavity between them. Read more. In the past, this depression was used to hold snuff (ground tobacco) before inhaling via the nose - hence it was .

In this study, 59 patients with clinical suspicion of scaphoid fracture and negative radiographs at presentation had a bone scan and MRI. The pronator teres muscle in the forearm can compress the median nerve, which may cause symptoms that mimic carpal tunnel syndrome. The base of this triangular shaped depression is located just distal to the end of the radius with the triangles apex pointing towards the thumb. This part of the scaphoid bone has a good blood supply, which is necessary for healing.

Recently, an alternative transradial access has been suggested at the anatomical snuffbox, with potential additional benefits including a reduction in radial artery occlusion rate (which allows reintervention through the same access site and potential use as a graft), a decrease in other local vascular complications, shorter hemostasis duration . Plain radiography and magnetic resonance imaging are usually not necessary for initial evaluation of a suspected nerve injury. Our engaging videos, interactive quizzes, in-depth articles and HD atlas are here to get you top results faster. When examining a patient with a suspected scaphoid injury, it is important to compare the injured wrist with the uninjured wrist. Pain with the scaphoid compression test (i.e., axially/longitudinally compressing a patients thumb along the line of the first metacarpal) also was shown, in a retrospective analysis,6 to be helpful in identifying a scaphoid fracture, but in another study,7 this technique had a poor predictive value for identifying scaphoid fractures. Scaphoid fractures that are closer to the thumb (distal pole) usually heal in a matter of weeks with proper protection and restricted activity. The floor of the snuffbox is made up of the scaphoid and trapezium carpal bones, which are located between the radial styloid process proximally and the base of the 1st metacarpal distally.

Nondisplaced fractures of this bone are known to be difficult to see on initial radiographs. AAOS does not endorse any treatments, procedures, products, or physicians referenced herein. The ulnar nerve at the elbow is very superficial and at risk of injury from acute contusion or chronic compression. This results in these two bones being the most often fractured of the wrist. Consider surgery sooner if late presentation with severe weakness or atrophy, progressive weakness: Long thoracic 36, 37: Further complications include; carpal instability (ligament disruption) and fracture-dislocations. If a cast is not applied, the fracture can worsen over the following months (Figure 4). Loss of infraspinatus function presents as weak external rotation of the arm.
