Compression of suprascapular nerve at the suprascapular notch or spinoglenoid notch can be a cause of a rare mononeuropathy. Patients complain of pain in scapula and shoulder, and selective wasting and weakness of the supraspinatus and infraspinatus muscles. Tenderness at the suprascapular notch and pain by forced abduction of arm are typical and useful signs. Electromyographic signs of various grade denervation are regularly found in both muscles. Development of entrapment syndromes is associated with chronic overload, shoulder injuries, with surgical procedures, or with shoulder-arm fixation. The authors present their own group of 10 patients, who were operated on for entrapment syndrome of suprascapular nerve during 7 year period. Direct or indirect traumatic mechanisms of development of nerve compression were disclosed in most patients. During postoperative period there was not only substantial decrease of pain, but also regression of weakness and wasting of both muscles. In discussion, necessity of differential diagnostic procedures in case of pain and muscle wasting, use of appropriate imaging techniques, demand of purposeful EMG examination, and postoperative follow-ups are emphasized.

The usefulness of carpal tunnel pressures measurement during surgery of carpal tunnel syndrome is documented by the authors. 31 patients underwent endoscopic uniportal approach, the pressure in different positions (neutral position, flexion and extension in wrist, grip of the fingers) and in different levels (distal forearm, proximal, central and distal part of carpal tunnel, palm) was measured. The significant drop of pressure was observed after dissection of ligament in all levels. The results are presented in the form of several graphs.

A significance of carpal tunnel pressure measurement during surgery of carpal tunnel syndrome (endoscopic and twin incision technique) was evaluated. The pressure in different levels of palm and in different positions of the hand was measured by ICP sensor Codman during operation of 10 patient. The results are presented in the form of several graphs. In all 10 cases excellent results were obtained.
