Summary
Endoscopic carpal tunnel release, using biportal Chow or uniportal Agee techniques, presents 31 potential complications, primarily affecting nerves. Careful technique and anatomical consideration are crucial for minimizing risks during carpal tunnel surgery.
Area of Science:
- Orthopedics
- Neurosurgery
- Surgical Anatomy
Background:
- Carpal tunnel syndrome (CTS) is a common condition requiring surgical intervention.
- Endoscopic carpal tunnel release (ECTR) offers minimally invasive options.
- Biportal Chow and uniportal Agee techniques are prevalent ECTR methods.
Purpose of the Study:
- To comprehensively review intra- and postoperative complications associated with endoscopic carpal tunnel release.
- To analyze the frequency and nature of complications, considering anatomical variations.
- To report complication rates from a prospective series using the uniportal Agee technique.
Main Methods:
- Literature review of biportal Chow and uniportal Agee techniques for ECTR.
- Analysis of 31 identified intra- and postoperative complications.
- Prospective study of 88 patients undergoing ECTR with the Agee technique.
Main Results:
- A total of 31 complications were identified in the literature review, with nerve structures being the most affected (14 cases).
- In the prospective series of 88 ECTR (Agee technique), 11 complications occurred, including residual symptoms, transient ulnar neurapraxia, and pain.
- Four cases required conversion to open surgery due to poor visualization during ECTR.
Conclusions:
- Endoscopic carpal tunnel release is associated with a range of complications, predominantly neurological.
- Understanding anatomical variations is key to managing and preventing complications in ECTR.
- The uniportal Agee technique demonstrated a manageable complication profile in this prospective series, though visualization challenges can necessitate conversion to open surgery.
