Abstract:
Percutaneous transforaminal endoscopic discectomy (PTED) is a minimally invasive technique to treat lumbar disk herniation from a lateral approach. Performed under local anesthesia, the incision size for PTED is around 8 mm with no paraspinal muscle cutting or detachment from their insertion. PTED has been associated with less blood loss, faster rehabilitation, and less scarring of tissue than conventional open microdiscectomy. High-quality randomized controlled trials comparing PTED with open microdiscectomy have not been conducted yet. However, PTED has been proven to be an effective technique allowing patients to return home only 2 hours after surgery. By the means of this article and video (Supplemental Digital Content 1, http://links.lww.com/CLINSPINE/A1), we would like to show the spine surgeon the PTED technique for the treatment of a single-level lumbar disk herniation.
Insights
Percutaneous transforaminal endoscopic discectomy (PTED) offers a minimally invasive option for lumbar disc herniation. This technique allows for faster recovery and same-day discharge, showcasing its effectiveness.
Area of Science:
- Minimally Invasive Spine Surgery
- Neurosurgery
- Orthopedic Surgery
Background:
- Lumbar disc herniation is a common condition requiring surgical intervention.
- Conventional open microdiscectomy involves significant tissue disruption.
- Minimally invasive techniques aim to reduce surgical trauma and improve patient outcomes.
Purpose of the Study:
- To demonstrate the technique of Percutaneous Transforaminal Endoscopic Discectomy (PTED).
- To highlight PTED as a minimally invasive treatment for single-level lumbar disc herniation.
- To provide a visual guide for spine surgeons on performing PTED.
Main Methods:
- PTED is performed via a lateral approach with local anesthesia.
- Utilizes a small incision (approx. 8 mm) without paraspinal muscle cutting.
- Focuses on the endoscopic visualization and removal of herniated disc material.
Main Results:
- PTED is associated with reduced blood loss and tissue scarring compared to open surgery.
- Patients undergoing PTED experience faster rehabilitation.
- Effective technique allowing same-day discharge (2 hours post-surgery).
Conclusions:
- PTED is an effective minimally invasive technique for lumbar disc herniation.
- The procedure offers advantages in terms of recovery time and patient comfort.
- Further high-quality trials are needed, but current evidence supports PTED's efficacy.
