Cauda Equina Syndrome After Percutaneous Endoscopic Discectomy At L5-S1: A case Report / 대한척추외과학회지

The Cauda Equina syndrome after spine surgery is a relatively uncommon condition, but it is a serious complication that needs emergency treatment. A 35-year-old woman was transferred to our hospital and she presented with decreased perianal sensation and rectal tone after percutaneous endoscopic discectomy. Magnetic resonance image showed that the dura sac was compressed by herniated disc material at L5-S1. After performing emergency open discectomy for the cauda eguina syndrome, the patient's neurologic symptoms were completely resolved at 12 months follow-up. There has been no previous report on Cauda Equina syndrome after percutaneous endoscopic discectomy, and so we report here on one case.

Comparison of Clinical Results According to Amount of Preserved Remnant in Arthroscopic ACL Reconstruction using Quadrupled Hamstring Graft / 대한정형외과학회잡지

PURPOSE: To analyze the clinical results in an ACL reconstruction according to the amount of the tibial remnant of the ACL using a hamstring graft and looped sutures. MATERIALS AND METHODS: Sixteen patients who were followed up for at least 12 months after the ACL reconstruction with four strands of a hamstring tendon using a looped suture technique were enrolled in this study. The average follow-up was 35.1 months. At the last follow-up period, the patients were evaluated using the International Knee Documentation Committee (IKDC) scale and the HSS score, Lachman test, ant. drawer test, KT-1000, one-leg hoop test and proprioceptive function test (motion and position sense). They were then divided two groups according to whether they had more or less than 30% of the ACL remaining. The final results of the two groups were statistically compared. RESULTS: Average HSS score improved from 65.8 (preoperative) to 95.2 (last follow-up). No significant differences in functional outcome and mechanical stability were found except for proprioception. Regarding the threshold of the detection of the passive motion test at 30 degrees (p=0.030) and the reproduction of the passive positioning test at 15 degrees (p=0.032) and 30 degrees (p=0.024), the more remnant preserved group (>30%) showed better results than the less preserved group. CONCLUSION: Preserving the tibial remnant will preserve function of the mechanoreceptors and be helpful to the recovery of the function and healing of a graft after surgery.
