Therapeutic IV.

Prospective randomized study of 120 patients of which 101 could be followed up. Forty-five patients (group A) had an open decompression and 47 (group B) were decompressed endoscopically. Average follow-up period for group A 271 days, for group B 275 days. Mean age of both groups: 53 years. There were 13 men and 41 women in group A and 17 men and 30 women in group B. No complications or night pain in either group. No significant difference in atrophy of the thenar eminence in the strength of the hand or in the 2 point discrimination. Results of pre- and postoperative nerve conduction and of temporary disability are listed in Figures 10 and 11. At follow-up 6 to 12 weeks postoperatively no difference could be found between the 2 groups in respect to scar pain, grip power and range of motion. Main advantage of the endoscopic approach: reduced postoperative pain and shorter disability.

The safety of the endoscopic technique for carpal tunnel release remains a major concern. Serious complications such as division nerves, tendons or vessels may occur. In this study the topography of the carpal tunnel was studied in fresh cadaver hands after the introduction of the blade assembly of a one portal system. By using a plastination method, it was possible to study the in situ relationships in detail by serial cross sections. Furthermore a modified Spalteholz method allowed the position of the blade to be viewed in whole specimens.
