Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Radiological examination include hand-wrist radiographs in the posteroanterior (PA), true lateral and 45º oblique views. A true lateral view of the hand may demonstrate the dislocation, although overlapping of the joints can mask the dislocation. On PA radiographs, Fisher et al. propose using the so-called M-line parallelism of the CMC joints. A break in this M-line suggests a dislocation. Another method is to draw metacarpal cascade lines on a PA radiographs.
It is important to recognise the associate lesions, for example hamate fractures, because this fracture can change the prognosis, surgical planning and treatment. The investigators hypothesized that there is an interobserver variability to evaluate the carpometacarpal fracture-dislocation and associated lesions in x-rays are underestimated. The investigators propose a protocol with a CT scan to asses this lesions. The researchers hypothesised that surgical reconstruction would result in better clinical result and lower complications rate than non-surgical treatment.
