Transforaminal percutaneous endoscopic discectomy for lumbar disc herniation in athletes under the local anesthesia

Abstract Background Percutaneous endoscopic discectomy (PED) has been reported to be less invasive and effective procedure for lumbar disc herniation (LDH). Damage to the back muscle is considered minimal, which is particularly important for athletes. However, the results of PED for LDH in athletes have not been reported well. The purpose of this study was to evaluate the clinical outcomes of PED for LDH in athletes. Methods We retrospectively analyzed 21 athlete patients with LDH who had undergone PED. All patients received athletic rehabilitation immediately after surgery. The clinical outcomes were evaluated from the visual analogue scale (VAS) for leg pain and low back pain (LBP), the Oswestry Disability Index (ODI), complications and periods of return to sport. Results There were 18 men and 3 women, and the mean age at the time of surgery was 22.9 years (range: 15–43 years). The mean VAS scores for leg pain before and after surgery were 64.3 ± 2.7 mm and 12.4 ± 1.4 mm, respectively. The mean VAS scores for LBP before and after surgery were 62.1 ± 2.2 mm and 10.5 ± 1.1 mm, respectively. The mean ODI scores before and after surgery were 31.3 ± 14.0% and 14.6 ± 7.1%, respectively. The VAS for leg pain, as well as the LBP and ODI, significantly improved after surgery. There were no complications related to the surgery. Ninety-five percent (20/21) returned to play sports at the same performance level as before the procedure by an average of 9.2 weeks after PED. Conclusions PED is a minimally invasive and effective procedure for patients with LDH, especially in athletes. Not only the patients' leg pain but also their discogenic LBP improved. PED has the benefits of preservation of normal posterior structures and a faster return to sports.
