Computerized axial tomography in obstetrical paralysis of the brachial plexus

For the past two years we have been using CT scan of the shoulders and humeri for all our patients affected with obstetrical paralysis of the upper limb, in addition to the routine clinical, electromyographic and radiographic examinations, thus integrating all the results. It opens up new perspectives in the study of the pathological anatomy of the shoulder and the upper extremity in obstetrical paralysis and has proved essential in the study of the following parameters: declination angle of the humerus; shape of the humeral head; joint congruence of the shoulder; orientation of the scapula. The non-invasiveness, tolerability, and precisation of this method have produced interesting results in 23 patients.
