Diagnostic Approach for Crampy Feeling in Hands and Fingers

Initial Diagnostic Approach

Standard radiographic evaluation of both hand and wrist should include three views: posteroanterior, lateral, and oblique, as recommended by the American College of Radiology, to assess alignment, joint spaces, impaction syndromes, static instability, chronic healed and nonunited fractures, soft tissue mineralization, erosions, and soft tissue swelling 1, 2, 3
Radiographs may be the only imaging examination needed to establish a diagnosis or confirm a clinically expected diagnosis, according to the American College of Radiology 1, 2

Ultrasound is recommended when soft tissue pathology is suspected, particularly for carpal tunnel syndrome, as it can demonstrate enlargement of median nerve cross-sectional area, space-occupying lesions, and anatomic variants, as suggested by the American College of Radiology 1, 2, 3, 4
Ultrasound is useful for dynamic assessment of the hand and wrist, evaluation of the contralateral side for comparison, and tendon pathology assessment, according to the American College of Radiology 2, 3, 4

MRI is indicated when radiographs are normal or show nonspecific findings but symptoms persist, and is useful for detailed evaluation of soft tissues, detection of carpal tunnel syndrome, identification of associated tendon pathology, and assessment of nerve compression syndromes, as recommended by the American College of Radiology 1, 2, 4, 5

For suspected muscle cramps without structural abnormalities, evaluation of electrolyte abnormalities, assessment for heat-related factors, and consideration of medication side effects are recommended, as suggested by the American College of Radiology 6
Failing to consider systemic conditions when bilateral symptoms are present, such as bilateral carpal tunnel syndrome, may be an early sign of certain systemic conditions or amyloidosis, according to the American College of Radiology 4
Ordering advanced imaging before appropriate radiographs have been obtained should be avoided, as recommended by the American College of Radiology 1, 2, 3
