A 52-year-old man developed isolated atrophy of the infraspinatus muscle. The suprascapular nerve was compressed at the spinoglenoid notch by a hypertrophied inferior transverse scapular ligament.
The authors report on the case of 22 patients who were operated on because of incisura scapulae syndrome. It is pointed out that this problem represents a borderline question and the projected incisura picture as well as the determination of the motor latency of the n. supraspinatus distalis play an important role in the separation of different diseases.

In 50 normal arms was measured the distal latency of the interosseus anterior nerve. The evoked potentials were detected in the flexor pollicis muscle. The distance was 15 cm between the stimulating and the recording electrodes. The main distal latency was 3.73 +/- 0.44 ms.

A transient myasthenic syndrome confirmed by EMG after taking large doses of beta blocking agent is reported. Data on similar complications have not been found in the literature. Theories trying to explain the myasthenic, myopathic effect of the beta-blocking agents are reviewed. In the opinion of the authors the quinidine-like membrane stabilising effect played a role in their case, although the possibility of the direct effect of the drug on the neurotransmitters cannot be excluded either.

Two cases of isolated sacral myeloradiculitis are described with retention of urine, sensory disorders in sacral segments and pleocytosis in the CSF. The patients were treated with steroids and recovered after 30 days of treatment. The differential diagnosis and literature are reviewed.

The article reports on a case which appeared as though two tunnel syndromes were present simultaneously, namely, the cubital and the carpal tunnel syndromes. Thorough electrophysiological examination revealed, however, that this simulated pattern was due to the presence of an anastomosis after Martin-Gruber. Three months after surgery the patient was free from symptoms. Intraoperative neurography had established the compression and its resolution. Anastomosis of Riche-Canieu was an additional, secondary finding.
