Advantages of Percutaneous Lateral Lateral Discectomy (PELD).1 Less surgical trauma: Compared to conventional open surgery, minimally invasive spine surgery has a smaller incision, causes very little damage to the paravertebral muscles, and does not destroy the bony and stable structures of the spine.2 Fast recovery: Conventional open surgery generally requires a recovery period of 1-3 months after surgery because of the great damage to the structures of the spine and the paravertebral muscles, whereas minimally invasive spine surgery requires a recovery period of 1-3 months because of the small damage to the structures of the spine and the soft tissues of the paravertebral muscles. Lateral approach surgery is usually performed 3 hours after surgery, and the patient is discharged from the hospital the next day and resumes normal work after 2 weeks.3 Definitive efficacy and low complications of nerve root injury: Studies have shown that many patients undergoing conventional open surgery experience postoperative low back pain due to excessive damage to the paravertebral muscles and soft tissues from open surgery. Minimally invasive spine surgery is less likely to damage the nerve roots because of the small damage to the paravertebral muscles and other soft tissues and almost no damage to the bony and stable structure of the spine, so postoperative low back pain rarely occurs with satisfactory results. The incision in conventional open surgery of the lumbar spine is generally 10-15 cm, while in minimally invasive spine treatment, the incision is generally 0.7-1 cm, which has almost no effect on the patient’s appearance.6 Short hospitalization time: the patient is generally discharged from bed 3 hours after surgery, discharged the next day, and resumes normal work after 2 weeks, which greatly reduces medical costs and is easily accepted by patients.7 Surgery is performed under local anesthesia. This is especially suitable for patients who cannot tolerate general anesthesia surgery due to systemic factors or older elderly patients.
