Endoscopic carpal tunnel release: a prospective study of complications and surgical experience.
A 63-center prospective study of endoscopic carpal tunnel release using the Agee Carpal Tunnel Release System was conducted in 1049 procedures in 988 patients. Prior experience with endoscopic release varied significantly among surgeon participants. Surgeons evaluated the newly redesigned system for blade visibility, blade height, and mechanical function. Data on patient complications were collected at the time of surgery and 3-4 weeks postoperative. The results indicated minimal complications 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 the transverse carpal ligament in 97.5% of procedures. Introduction of the 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.
