Patients were divided into Group A (quadrant channel technology) and Group B (delta large channel technology), which comprised 28 and 34 patients, respectively. The factors compared between the two groups were operation time, length of incision, blood loss, ambulation time, length of hospitalization, visual analogue scale (VAS) preoperatively, 7 days postoperatively, and 30 days postoperatively, and Oswestry dysfunction score (ODI).Results: The length of incision, blood loss, ambulation time, and length of hospitalization stay in Group A were significantly higher compared with Group B (P < 0.05). There was no significant difference between the two groups in operation time, preoperative ODI index, preoperative VAS scores, and thirty-day postoperative VAS scores (P > 0.05). The seven-day postoperative VAS score, seven-day postoperative ODI index, and thirty-day postoperative ODI index of Group A were significantly higher than those of Group B (P < 0.05). The preoperative VAS score and ODI index in both groups were significantly higher compared with after operation (P < 0.05).Conclusion: Both surgical methods achieved a good clinical outcome in the treatment of lumbar degenerative diseases. The delta large channel technique may offer some advantages over quadrant channel technology, such as less trauma and bleeding and faster recovery time.Keywords: quadrant channel, delta large channel technique, lumbar degenerative diseases
