简要总结
Lumbar degenerative diseases such as lumbar disc herniation (LDH) and lumbar spinal stenosis (LSSS) are common and frequently encountered in orthopaedics. With the acceleration of the aging process of society, their incidence rate increases year by year. At present, conservative treatment is the preferred choice for this type of disease, and surgical treatment is feasible in cases where conservative treatment is ineffective. The main surgical methods include simple laminectomy and nucleus pulposus removal, intervertebral fusion and internal fixation, intervertebral disc replacement, and non fusion surgery. Simple nucleus pulposus removal surgery has drawbacks such as loss of intervertebral height and foramen height, which can affect spinal stability; Intervertebral fusion and internal fixation surgery has the problem of accelerating adjacent segment degeneration; The current therapeutic effect of lumbar disc replacement is not yet clear, and the technology is not yet mature. In response to the shortcomings of the above surgical methods, the advancement of science and technology has driven the development of spinal surgery, and a new surgical concept has emerged - spinal non fusion fixation technology. The INTRA-Spine dynamic stability system between vertebral lamina is one of the non fusion technologies of the spine. The core concept of this technology is to provide dynamic fixation on the basis of sufficient decompression of nerves, with the rotation center located between the vertebral lamina, which is closer to the normal movement center of the lumbar spine. It simulates the normal physiological structure of the lumbar spine with minimal damage and trauma, and maximizes the preservation of surgical segment mobility while maintaining spinal stability, Reducing stress concentration in adjacent segments caused by local fusion, thereby reducing the acceleration of adjacent segment degeneration, theoretically has good clinical and imaging efficacy.
详细描述
Retrospective analysis of patients admitted to the Department of Orthopedic and Spinal Surgery of our hospital who underwent the INTRA Spine dynamic stabilization system and lumbar fusion technology for the treatment of lumbar degenerative diseases. General, clinical, and imaging data were collected before and 7 days, 6 months, and 12 months after surgery. The general information of the patient includes gender, age, course of disease, conservative treatment time, surgical time, nail/implant placement time, bleeding volume, and length of hospital stay; The clinical treatment effect was evaluated using the visual analogue VAS score for low back and leg pain, the Japanese Orthopedic Association's JOA score for evaluation of treatment, and the Oswestry Dysfunction Index questionnaire ODI score; The imaging data includes measuring the lateral position of the surgical segment and adjacent segments through lumbar lateral X-ray films, the Cobb angle, flexion and extension range of motion (ROM), intervertebral disc height, and intervertebral foramen height in the over extension and over flexion positions. The optimal measurement angle value is used, and each measurement data is measured three times and its mean is taken. Perform analysis of variance (intra group follow-up time) and t-test (inter group) on the obtained data using statistical software SPSS; Statistics and analysis of clinical efficacy and imaging manifestations.This clinical study has a funding of 50000 RMB.

结局指标
主要结局
Cobb angle of surgical space and adjacent space in neutral position, over extension and over flexion position
时间窗: 2 Years
Cobb angle of surgical space and adjacent space in neutral position, over extension and over flexion position
VAS
时间窗: 2 Years
The visual analog scale (VAS) is used for pain assessment. It is widely used in clinical practice in China, and the basic method is to use a vernier ruler with a length of about 10cm, marked with 10 scales on one side, with both ends marked as "0" and "10" respectively. A score of 0 indicates painlessness, and a score of 10 represents the most severe pain that cannot be tolerated.
JOA
时间窗: 2 Years
The Japanese Orthopaedic Association Scores (JOA) is a neurological function scoring system recommended by the Japanese Orthopaedic Association, which includes four parts: upper limb motor function, lower limb motor function, sensory and bladder function, with a total score of 29 points. The lower the score, the more severe the neurological dysfunction.
