[Preliminary comparative study of spinal robot-assisted pedicle screw placement using different surgical approaches].

Objective: To compare the effectiveness of spinal robot-assisted pedicle screw placement through different surgical approaches and to guide the clinical selection of appropriate robot-assisted surgical approaches.

Methods: The clinical data of 14 patients with thoracolumbar vertebral diseases who met the selection criteria between January 2023 and August 2023 were retrospectively analyzed, and all of them underwent pedicle screw placement under assistant of the Mazor X spinal surgery robot through different surgical approaches. The patients were divided into posterior median approach (PMA) group ( =6) and intermuscular approach (IMA) group ( =8) according to the surgical approaches, and there was no significant difference in age, gender, body mass index, disease type, and fixed segment between the two groups ( >0.

Long-term clinical observation of patients with acute and chronic complete spinal cord injury after transplantation of NeuroRegen scaffold.

Spinal cord injury (SCI) often results in an inhibitory environment at the injury site. In our previous studies, transplantation of a scaffold combined with stem cells was proven to induce neural regeneration in animal models of complete SCI. Based on these preclinical studies, collagen scaffolds loaded with the patients' own bone marrow mononuclear cells or human umbilical cord mesenchymal stem cells were transplanted into SCI patients.

Comparison of the Effectiveness of Radiofrequency Neurotomy and Endoscopic Neurotomy of Lumbar Medial Branch for Facetogenic Chronic Low Back Pain: A Randomized Controlled Trial.

Objective: To compare the effectiveness of radiofrequency neurotomy (RN) and endoscopic neurotomy (EN) of lumbar medial branch (MB) for facetogenic chronic low back pain (FCLBP).

Methods: Forty patients with FCLBP were included and randomly assigned to the control group and the experimental group. The control group (20 cases) underwent X-ray-assisted RN and the experimental group (20 cases) underwent EN of the lumbar MB.

Risk factors for non-fusion segment disease after anterior cervical spondylosis surgery: a retrospective study with long-term follow-up of 171 patients.

Background: The purpose of this study was to investigate the incidence and causes of non-fusion segment disease (NFSD), both adjacent and non-adjacent to a fused segment, after anterior cervical arthrodesis.

Methods: This is a single-center study. Between January 1998 and January 2011, two surgeons' 171 patients who had an anterior cervical decompression and fusion were followed clinically for more than 5 years.

Modified Percutaneous Lumbar Foraminoplasty and Percutaneous Endoscopic Lumbar Discectomy: Instrument Design, Technique Notes, and 5 Years Follow-up.

Background: Conventional percutaneous endoscopic lumbar discectomy (PELD) with an "inside-outside" technique has 4.3% - 10.3% surgical failure rate, especially in central herniated discs (HDs), migrated HDs, and axillary type HDs.

New instrument for percutaneous posterolateral lumbar foraminoplasty: case series of 134 with instrument design, surgical technique and outcomes.

Current solutions for treating uncontained lumbar disk herniation include laser assisted endoscopic foraminoplasty and Transforaminal Endoscopic Spine System, both of which have some issues in clinical practice. This study aims to report the design of a new instrument for percutaneous posterolateral foraminoplasty. 148 patients with uncontained lumbar disk herniation were treated with percutaneous foraminoplasty followed by transforaminal endoscopic discectomy.

Adipose-derived stem cells improve the viability of nucleus pulposus cells in degenerated intervertebral discs.

Patients with degenerative disc disease (DDD) experience serious clinical symptoms, including chronic low back pain. A series of therapies have been developed to treat DDD, including physical therapy and surgical treatment. However, the therapeutic effect of such treatments has remained insufficient.

The strategy and early clinical outcome of full-endoscopic L5/S1 discectomy through interlaminar approach.

Objective: To analyze the surgical strategy, safety and clinical outcome of full-endoscopic discectomy through interlaminar approach in the case of L5/S1 intervertebral disc excision.

Methods: From April 2011 to December 2011, 72 cases of intracanalicular non-contained disc herniations at L5/S1 level were treated with full-endoscopic discectomy through interlaminar approach. L5/S1 disc herniation was divided into three types according to position of herniated disc related to S1 nerve root: axilla type, ventral type and shoulder type.

Evaluation of endoscopic dorsal ramus rhizotomy in managing facetogenic chronic low back pain.

Objective: To study the effectiveness of surgical dorsal endoscopic rhizotomy for the treatment of facetogenic chronic low back pain.

Methods: From April 2011 to November 2011, 58 patients who were diagnosed with lumbar facetogenic chronic low back pain (CLBP) and thereafter experienced >80% reliefs of pain with two comparative lumbar medial branch blocks were recruited in the study. Of those 58 patients, 45 cases (the operation group) received dorsal endoscopic rhizotomy, and the remaining 13 cases (the conservative group) received conservative treatment.

Establishment of a rat model of adjuvant-induced osteoarthritis of the lumbar facet joint.

To study the establishment of adjuvant-induced osteoarthritis of the lumbar facet joint in a rat model. Complete Freund's adjuvant (experimental group) and saline (control group) were randomly injected into the right and left side of rat, respectively. The rats were killed, and degeneration of lumbar facet joint was evaluated at macroscopic level and scored based on OARSI scores system.
