The pronator teres muscle in the forearm can compress the median nerve, which may cause symptoms that mimic carpal tunnel syndrome. A particularly cavernous anatomical snuff box. Other studies have shown that MRI might be better than scintigraphy because the former is more sensitive and specific.10 One clinical study11 did find that early MRI after negative plain radiographs of suspected scaphoid fractures changed management strategies 90 percent of the time. Results of one study9 showed that with the use of dedicated-extremity MRI, scaphoid fractures could be diagnosed earlierwithout waiting the usual two weeks to repeat the plain films. If the scaphoid is broken in the middle of the bone (waist) or closer to the forearm (proximal pole), healing can be more difficult. Difficult.
