Protection of L1 nerve roots by pre-relieve tension in parallel endplate osteotomy for severe rigid thoracolumbar spine deformity

Abstract

Background: This is a retrospective study of the use of parallel endplate osteotomy (PEO) for correction of severe rigid thoracolumbar spine deformity. Methods: From July 2016 to January 2019, 12 patients with severe rigid thoracolumbar spine deformity underwent PEO on T12 or L1 vertebrae were studied. Results: Following PEO at T12 or L1, the mean kyphosis and scoliosis correction rates reached 77.0 ± 8.9% and 75.5 ± 8.0%, respectively and the intraoperative estimated blood loss was 1950 ± 1050 mL, and the mean operative time was 6.98 ± 4.02 h. The SF-36 scores of physical function, role-physical, bodily pain, general health, vitality, social function, role-emotional and mental health changed from 63

Efficacy and Safety of Rivaroxaban for Extremely Aged Patients with Venous Thromboembolism: A Retrospective, Cross-Sectional Real-World Study

“…36 In the last few years, investigators have determined the predictive value of the ACCI on the long-term prognosis of patients with malignant tumors (such as ovarian cancer, prostate cancer, pancreatic cancer, gastric cancer, colorectal cancer, hilar cholangiocarcinoma and so on). [37][38][39][40][41][42][43] Recently, ACCI has also been regarded as a haemorrhagic and thrombotic scoring system. 26 However, the predictive value of the ACCI score on the efficacy and safety of rivaroxaban in patients with VTE has not been reported.…”

Evaluation of parallel endplate osteotomy for severe rigid spinal deformities: a retrospective analysis of 36 cases with a minimum 2-year follow-up

“…Those osteotomies are mostly PSO, VCD, eggshell and so on. PEO, which has been described in our previously published paper [ 15 ], includes the pedicle of the vertebral arch, 4/5 of the posterior vertebra, the bilateral walls of the vertebra and the posterior wall of the vertebra (5 mm to the endplate), which does not require thorough pedicular osteotomy like PSO and resection of the intervertebral disc above and below the osteotomy site like VCR. Moreover, the endplate as a mark in PEO is easy to identify which has a large operating space, and is especially suitable for pedicle deformity or agenesis which is unrecognizable, which is easier to operate for orthopedic surgeons.…”

“…All surgeries were performed as a single-stage procedure by a single surgeon (the corresponding author, SXD) through a posterior incision. The surgical procedure has been described in our previous paper [ 15 ].…”
