BACKGROUND: The scaphoid is the commonest fractured carpal bone, but excluding a scaphoid fracture with plain radiographs is difficult. Other imaging modalities are being increasingly evaluated in the management of scaphoid injuries. MRI has been shown to be of considerable value in the adult ...
然而,一些非移位的舟状骨骨折可能直到受伤后几周才在X线下显现,因此可能需要重复进行X线检查。骨扫描,MRI或CT扫描可能也是必要的。 Treatment(治疗) Treatment for scaphoid fractures depends on the fracture location and the presence of fracture displacement...
It would appear from this study that MRI is regarded as a useful modality in cases whereby plain film radiography fails to detect the presence or absence of a fracture in clinically positive patients, with great future potential. 展开 关键词: Radiography Magnetic resonance imaging Scaphoid Fractures...
Comparison of CT and MRI for Diagnosis of Suspected Scaphoid Fractures. Methods: Thirty-four consecutive patients with a suspected scaphoid fracture (tenderness of the scaphoid and normal radiographic findings after a fall on the... Mallee,Wouter,Doornberg,... - 《Journal of Bone & Joint Surgery...
If repeat radiographic imaging is negative, however clinical findings are still in keeping with a scaphoid fracture, anMRI scan of the wristis indicated. This is the definitive investigation and, whilst it is awaited, the interim management is as for a fracture. ...
Magnetic resonance imaging (MRI) scan.The MRI may show a scaphoid fracture quicker than an X-ray can. Computerized tomography (CT) scan.A CT scan can reveal the scaphoid fracture to help your doctor develop the best treatment plan.
The scaphoid fracture may not be very clearly seen on routine wrist X-rays. Special views such as the semi-pronated or ulnar deviation views are usually performed to better delineate the fracture. Figure A: A CT scan or MRI may sometimes be required to evaluate the scaphoid to greater resolu...
2. Appropriately evaluate a patient with suspected scaphoid fracture, including appropriate imaging. 3. Understand the indications for operative treatment of scaphoid fractures, and be familiar with the various surgical approaches. 4. Describe the treatment options for scaphoid nonunion and avascular ...
The tracers then show up on special X-rays of your wrist. The tracers build up in areas of extra stress to bone tissue, such as a fracture. Your doctor may also order a magnetic resonance imaging (MRI) scan. An mri scan is a special imaging test that uses magnetic waves to create ...
However, when the fracture is not displaced, x-rays taken within the first week may not reveal the fracture. A non-displaced scaphoid fracture could thus be incorrectly diagnosed as a “sprain” because the x-ray was “negative.” Therefore a patient who has significant tenderness directly ...
