OBJECTIVE: The objective of this study was to compare the diagnostic value of panoramic and conventional radiography in the detection of fractures of the carpal scaphoid bone.
MATERIALS AND METHODS: Panoramic (orthopantomographic) and conventional radiographs of 90 patients with acute or chronic wrist trauma were reviewed retrospectively. Images were analyzed and reviewed independently by four observers: two radiologists and two traumatologists. The kappa statistic was used to calculate intraand interobserver agreement and the correlation between the two imaging techniques.
RESULTS: Panoramic radiography of the wrist was superior to conventional radiography in ruling out scaphoid fractures (74%, 20/27) in patients with suspicious findings on conventional radiography; revealed more cases of scaphoid fractures (21.4%, 12/56); and revealed more cases of delayed union (n = 2), nonunion (n = 3), and union (n = 3). Agreement values were higher, with better inter- and intraobserver agreement, for the panoramic examinations than for the conventional radiographic examinations.
CONCLUSION: The panoramic examination of the wrist is a useful technique for the diagnosis and follow-up of scaphoid fractures. Its use is recommended as a complement to conventional radiography in cases with inconclusive findings.
