[Objective]To explore the short-term outcome of targeted foraminoplasty in percutaneous endoscopic lumbar discectomy(PELD).[Methods]A retrospective study was conducted on 28 patients who underwent targeted foraminoplasty in PELD for lumbar disc herniation from September 2017 to March 2018 in our institution.Their clinical outcomes were evaluated with Visual Analogue Scale(VAS)for leg pain and back pain score,Oswestry disability index(ODI),modified MacNab's criteria as well.[Results]All patients received successful surgical procedures with operation time of 25~90 min,intraoperative blood loss of 10~25 ml,frequency of fluoroscopy of 8~15 times,and hospital stay of 4 to 7 d.No serious complications happened in any of them,such as nerve injury,dural tear and infection.All of them were followed up for 7~12 months with an average of(9.30±2.28)months.Both the VAS and ODI scores significantly decreased postoperatively compared with those before operative,with statistically significant differences(P<0.05).In term of Modified MacNab's criteria,the clinical results were graded as excellent in 18,good in 8,fair in 1 and poor in 1.[Conclusion]This targeted foraminoplasty in PELD is an effective and safe treatment for lumbar disc herniation with advantages of reducing the difficulty in PELD and minimizing radiation exposure.
