Twenty-eight wrists of 25 patients with carpal tunnel syndrome (CTS) and 28 wrists of 14 normal control subjects were studied with high-frequency real-time ultrasonography. Three general findings could be observed in CTS, regardless of its cause: swelling of the median nerve at the entrance of the carpal tunnel; flattening of the median nerve in the distal carpal tunnel; and increased palmar flexion of the transverse carpal ligament. Quantitative analysis proved these findings to be significant. We conclude that high-resolution sonography is able to diagnose median nerve compression in the carpal tunnel syndrome and to detect some of its potential causes.

Precise clinical and electroneurographic examinations were made of 51 patients before and after anterior transposition of the ulnar nerve. The mean follow-up period was 9.6 years. In 86%, hand function improved, while in 10% it remained unchanged. Subcutaneous transposition was better than submuscular transposition, especially with regard to sensation. This method is simple and involves low morbidity for patients.

The authors conclude that the rate of postoperative bleeding in face lifts under the use of low-molecular-weight heparin is higher than generally expected. As no symptomatic thrombosis or embolism without using low-molecular-weight heparin occurred, it seems that the use of low-molecular-weight heparin in face lifts is not categorically necessary in low-risk patients.
