Jm. Agee et al., ENDOSCOPIC CARPAL-TUNNEL RELEASE - A PROSPECTIVE-STUDY OF COMPLICATIONS AND SURGICAL EXPERIENCE, The Journal of hand surgery, 20A(2), 1995, pp. 165-171
A 63-center prospective study of endoscopic carpal tunnel release usin
g the Agee Carpal Tunnel Release System was conducted in 1049 procedur
es in 988 patients. Prior experience with endoscopic release varied si
gnificantly among surgeon participants. Surgeons evaluated the newly r
edesigned system for blade visibility, blade height, and mechanical fu
nction. Data on patient complications were collected at the time of su
rgery and 3-4 weeks postoperative. The results indicated minimal compl
ications and no confirmed injuries to vessels or nerves; the symptoms
from one possible digital nerve injury eventually resolved completely.
Surgeons were able to observe the point of entry of the blade into th
e transverse carpal ligament in 97.5% of procedures. Introduction of t
he blade assembly into the carpal tunnel was rated easy or adequate in
90.6% of procedures, and blade height was rated adequate in 97.4% of
procedures.
