Previous studies have shown that a scaphoid fracture is the most common frac-ture among patients with post-traumatic radial-sided wrist pain.1,2 Scaphoid fractures are notorious for .

Definitive diagnosis should be made with computed tomography and magnetic resonance to verify the presence of displacement. This article provides an overview of the incidence and presentation of acute scaphoid . An altered motion pattern during axial load compression may be an indicator of scapholunate ligament injury.

Clinically, scaphoid fractures manifest with wrist pain, tenderness to palpation of the anatomic snuffbox, and pain with axial loading of the thumb, which transmits force to the scaphoid. On .

Repeat Wrist and scaphoid X-rays should be obtained 2-3 weeks after initial injury to assess for fracture if suspicion is high.Of 52 patients with suspected scaphoid fractures, 37 had negative tests and proved by X-rays then and later to have no fracture. 12 had positive tests and X-rays. Two patients with positive tests had fractures nearby: one of the scaphoid tuberosity and one of the radial styloid. One patient with a negative test had de Quervain’s disease. Differentiating a wrist sprain from a scaphoid fracture is a clinically useful skill. The scaphoid compression test, included in Duckworth's clinical predica.

To perform the TFCC Compression Test according to Prosser et al. in the year 2011, fixate your patient’s radius and ulna with one hand close to the joint line.

Other potential pain generators from compression include dorsal wrist impingement and scaphoid impaction syndrome. Carpal bosses, dorsal wrist ganglia, dorsal wrist impingement, and scaphoid impaction syndrome are usually . Pathology. The usual mechanism is falling on an outstretched hand, applying an axial load to an extended and pronated wrist in ulnar deviation 7.Occasionally stress fractures are also encountered although these are less common, and only usually seen in athletes (e.g. shot putters or gymnasts) 8.

Scaphoid Scaphoid fracture Dorsal approach Compression screw Wrist KEY POINTS Scaphoid fractures are the most common carpal bone fracture, and 10% to 15% may present with normal radiographs. Computed tomography (CT) or MRI remain the best means of ruling out a fracture, whereas CT re-mains the best means of determining scaphoid displacement.Provocation tests: Watson's test "scaphoid shift test" Test is performed by the examiner stabilizing the scaphoid with one hand while using the other hand to move the wrist from ulnar to radial deviation.

There is no standard definition of a "normal" result for the scaphoid shift test since the test is primarily used to detect abnormal motion or .

MRI is not only expensive, but most emergency departments have restricted access to this investigation. Plain radiographs miss up to 25% of scaphoid fractures across all age groups (Pincus, 2009), but this is our most readily available test. A scaphoid series of plain X-rays includes four views: posteroanterior (PA), pronated, lateral, and . Tenderness is usually found upon radial deviation and flexion of the wrist, and pain is usually found with the Watson maneuver. Another useful sign may be pain with scaphoid compression via axial load to the first metacarpal. Patients not uncommonly present with diminished grip strength when compared to the contralateral wrist.
