About dynamic msk imaging modalities in the study of post-traumatic metacarpal fracture
Acute 4th metacarpal spiroid fracture of a professional football goalkeeper; first diagnosis was made directly on pitch with an ultrasound examination. Plain radiographs and Mri exam were performed just one hour after trauma.
One month after surgical fixation the fracture is studied with dynamic US, Mri and Cone-Beam CT imaging. The US and MR dynamic evaluations, show a regular tendon sliding over the fixation devices.
No metal-induced artifacts were seen, allowing a perfect visualization of the implanted devices.
Cone-Beam CT Sagittal (left) and Coronal (right) reconstructions.
The study was completed with dynamic Mri (0.3 Tesla) and Cone-Beam CT scans, performed with active flexion-extension of carpal-metacarpal joint structures.
about dynamic ultrasound and mri evaluation of partial patellar tendon tear
Today I show you the case of a partial tear at proximal insertion of the patellar tendon in a professional football player. The patient refears pain during flexion-extension at inferior patellar pole; hystory of repetitive trauma as usual in football players.
