Computerized Tomography to Help Diagnosis Pediatrics Scaphoid Fractures.

The Efficiency of Computerized Tomography to Aid in the Diagnosis of Pediatrics Scaphoid Fractures

The purpose of this study is to find out whether computerized tomography will be better than plain radiographs in determining pediatrics scaphoid fractures.

Background: The use of plain radiograph in the detection of pediatrics scaphoid fractures has low specificity and sensitivity. Patients with documented anatomical snuffbox tenderness and negative plain radiographs are casted in thumb spica casts and seen by a pediatrics orthopedics surgeon. However few patients with clinical scaphoid fractures have documented scaphoid fractures, with the most common injury of soft tissue injury to the surrounding tissues. The use of CT scan to detect scaphoid fractures is not well documented and may be an appropriate substitute for plain radiographs.

Hypothesis: CT scan of the wrist will have higher sensitivity and specificity in detecting pediatrics scaphoid fracture than plain radiographs.

Inclusion Criteria:

• Pain in anatomical snuffbox, Negative radiographs, less than 18 years old, older than 6 years old, injury less than 1 week old and provision of informed consent

Exclusion Criteria:

• Previous injury to scaphoid bone, other injuries on the same extremity, vascular injury present at the injury site, fracture seen on initial radiographs, injury >1 week old, inability for patient to comply with rehabilitation or form completion, likely problems in maintaining patient follow-up
