“…Many recent studies suggest equal sensitivity and better (sometimes 100%) specificity for MR imaging in accurately detecting radiographically occult scaphoid fractures [3,4,15,16]. On MR imaging, the fracture line will appear as a discrete focus of linear low T1 and T2 signals.…”

“…Bone bruises of other carpal bones and seven other carpal fractures were also detected. Cook et al [16] found seven patients with evidence of extensor tenosynovitis on MR imaging. Thorpe et al [15] found frequent occurrences of ligamentous injury and carpal instability at MR imaging that were not evident on scintigraphy.…”

“…2). Scaphoid fractures not visible on initial plain radiographs are reported to occur from 7% to 80% [12][13][14][15]. A large meta-analysis showed that occult fractures correspond to approximately 16% of all scaphoid fractures [16].…”

“…A large meta-analysis showed that occult fractures correspond to approximately 16% of all scaphoid fractures [16]. MRI is able to disclose occult fractures offering 100% sensitivity, 100% specificity [16][17][18][19] and in the immature skeleton a negative predictive value of 100% [14]. The fracture is shown as a low signal intensity line on all MR sequences extending from cortex to cortex (Fig.…”

The role of MR imaging in scaphoid disorders

The scaphoid bone of the wrist is one of the most commonly fractured bones in the body. Due to its importance in the biomechanics and functionality of the wrist, it is important to depict and characterize the type of injury. Plain radiographs and scintigraphy may fail to disclose the type and severity of the injury. In patients with normal initial plain radiographs, MR imaging can discriminate occult fractures from bone bruises and may also demonstrate ligamentous disruption. MR imaging can also discriminate the proximal pole viability versus avascular necrosis secondary to previous fracture, which is important for treatment planning. Treatment of non-united fractures with vascularized grafts can be evaluated with contrast-enhanced MR imaging. Idiopathic osteonecrosis or Preiser's disease was originally described after trauma. The non-traumatic disorders of the scaphoid include post-traumatic osteoarthritis, inflammatory bone marrow edema in patients with rheumatoid arthritis, and osteomyelitis. MR imaging is helpful in all the above disorders to demonstrate early bone marrow edema, cartilage degeneration and associated subchondral marrow changes. The most commonly found tumors in the scaphoid are usually benign and include enchondroma, osteoblastoma and osteoid osteoma. MR imaging is not mandatory for the initial diagnosis, which should be based on plain X-ray findings.

Suspected Scaphoid Fractures in Skeletally Immature Patients: Application of MRI

Abstract: A normal initial MR image had a negative predictive value of 100%. Persistent snuffbox pain may represent injury to the scaphoid, extensor tendons, or dorsal soft tissues. An outcome study evaluating the benefits of early application of MR in the pediatric population is warranted.
