ed, and lumbar spondylolisthesis aggravates intervertebral disc and facet joint degeneration.

Lumbar spinal pelvic structure of degenerative lumbar spondylolisthesis has undergone significant changes. Lumbar lordosis and pelvic dumping phenomenon in the mechanism of lumbar degeneration plays an important role. Lumbar facet joint degeneration and lumbar intervertebral disc degeneration are mutually promoted, and lumbar spondylolisthesis aggravates intervertebral disc and facet joint degeneration.

To assess the early clinical effects of oblique lateral lumbar interbody fusion (OLIF) combined with posterior long-segment internal fixation through O-arm CT navigation for the treatment of degenerative scoliosis.

The clinical data of 15 patients with degenerative scoliosis treated by OLIF combined with posterior long-segment internal fixation through O-arm CT navigation between April 2016 and December were retropectively analyzed. There were 3 males and 12 females, aged from 55 to 73 years old with an average of (62.2±5.3) years. The operation time, intraoperation blood loss, the rate of excellentand good of pedicle screw placement, and complications were recorded. Before surgery, 1 week after surgery and at the final follow-up, the visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the patients' clinical symptoms;standing X-ray film, lumbar spine CT examination was performed at 6 months after surgery to observe coronal scoliosis Cobb angle, lumbar lordosis (LL), interth posterior long segment internal fixation through O-arm CT navigation is satisfactory in treatment of degenerative scoliosis. It has the advantages of minimal invasion, accurate navigation of nail placement, high bone fusion rate and few complications. It can provide new options for minimally invasive treatment of degenerative scoliosis.

To explore the clinical effect of channel-assisted minimally invasive transforaminal lumbar interbody fusion combined with percutaneous short segmental vertebral fixation for the treatment of non-specific lumbar intervertebral infection.

The clinical data of 12 patients with non-specific lumbar intervertebral infection treated from January 2014 to January 2018 were retrospectively analyzed. There were 8 males and 4 females, aged 39 to 65(51.00±12.36) years old. Infection site located in L2, 3 of 2 cases, L3, 4 of 3 cases, L4, 5 of 6 cases, L5S1 of 1 case. There were 3 cases of hypertension, 2 cases of diabetes, and 2 cases of urinary tract infection. None of the 12 patients had a history of lumbar puncture and surgery. Debridement, autogenous bone grafting, minimally invasive transforaminal lumbar interbody fusion via Quadrant invasive system, and percutaneous short segmental vertebral fixation were performed in the patients, the diseased tissue samples were collected for bacterial culture and pathologicaand minimally invasive transforaminal lumbar interbody fusion via Quadrant invasive system combined with percutaneous short segmental vertebral fixation is a safe, clinically reliable, minimally invasive surgical procedure for the treatment of non specific lumbar intervertebral space infections.

Debridement, autogenous bone grafting and minimally invasive transforaminal lumbar interbody fusion via Quadrant invasive system combined with percutaneous short segmental vertebral fixation is a safe, clinically reliable, minimally invasive surgical procedure for the treatment of non specific lumbar intervertebral space infections.

To explore the clinical effects of anterior cervical discectomy with fusion (ACDF) and anterior cervical corpectomy with fusion (ACCF) in treating adjacent two-segment cervical spondylotic myelopathy (CSM).

The clinical data of 37 patients with adjacent two segment CSM treated from January 2016 to December 2017 were retrospectively analyzed, including 15 males and 22 females, aged from 43 to 69 years old with an average of 54.6 years. The patients were divided into ACDF group (group A,

=17) and ACCF group (group B,

=20) according to the different surgery. The operation time and intraoperative blood loss were recorded;the Cobb angle and cervical curvature in the cervical fusion segments before surgery and 1, 12 months after surgery were observed;Japanese Orthopaedic Association (JOA) score was used to evaluate the surgical efficacy, and the postoperative complications were analyzed.

All patients were followed up for 12 to 24 months with an average of 18.5 months. Operation time and intraoperative blong-term follow-up shows that ACDF and ACCF have good surgical procedures, mature technology, and close efficacy.

Two types of anterior cervical decompression and fusion for the treatment of two segment cervical spondylotic myelopathy can effectively decompress and improve the Cobb angle and cervical curvature of the affected vertebra. The ACDF surgical procedure can directly removethe compressive thing at intervertebral level, which will lead to little vertebral body damage and favorably recovered cervical curvature. The ACCF surgical procedure has a large operation space, which can easily remove the posterior vertebral osteophyte and the calcified posterior longitudinal ligament. Gefitinib EGFR inhibitor Long-term follow-up shows that ACDF and ACCF have good surgical procedures, mature technology, and close efficacy.

To evaluate the early clinical efficacy and safety of vesselplasty for the treatment of spinal metastases complicated by posterior wall destruction of vertebral body.

The clinical data of 19 patients(21 segments) with spinal metastases complicated by posterior wall destruction of vertebral body treated from January 2016 to January 2017 were retrospectively analyzed. There were 15 males and 4 females, aged 40 to 85 years old with a mean of (66.00±10.25) years . All patients had severe low back pain before the operation, which were diagnosed by CT as damage-type metastatic tumor of the vertebral posterior wall. All patients were treated by vesselplasty technique. Nineteen vertebrae received percutaneous unilateral pedicle puncture and two vertebrae received percutaneous bilateral pedicle puncture. VAS, ODI were recorded before operation, 1 d and 3 d after operation respectively. X-ray and CT scan were used to observe bone cement leakage and complications.

All the operations were successful and postoperative pain was significantly relieved.
