Description for medicine or protocol of treatment in detail: |
[Product Performance and Main Structural Components] This product is made of TC4 alloy powder material that meets the chemical composition requirements of the GBT 13810 standard, manufactured using laser selective melting technology. The product has a hollow structure, with the outer ring designed as a bone-like trabecular porous structure, and both the upper and lower end surfaces designed with multiple anti-slip teeth. The product is delivered in either sterilized or non-sterilized packaging. Sterilized packaging products are sterilized by irradiation and have a shelf life of 4 years. Non-sterilized packaging products have a shelf life of 8 years. [Scope of Application] This product is intended to be used in conjunction with a spinal internal fixation system, providing intervertebral stability during cervical (C2/3-C7/T1) and thoracolumbar (T1/2-L5/S1) fusion surgeries, maintaining intervertebral height, and facilitating intervertebral fusion. [Installation and Usage Instructions] 1. Formulate the surgical plan, determine the required surgical approach, and select the model and size of the interbody fusion cage based on X-rays. 2. Use the standard surgical approach to expose the vertebrae to be fused. Prepare the fusion area according to the surgical procedure specified for the indication, and use a burr to trim the inferior edge of the upper vertebra and the superior edge of the lower vertebra so that they match the edges of the trial mold and prosthesis. 3. Choose the trial mold according to the intervertebral height, intervertebral preparation technique, and the patient’s anatomical shape. Properly position the trial mold along the correct cranial-caudal direction and insert it into the intervertebral space. Determine the required size of the fusion cage based on the most suitable trial mold. 4. Use a distractor or distraction screws to open the intervertebral space and adjust to the proper intervertebral height. 5. Using implantation instruments, place the fusion cage filled with autologous bone onto the holder and implant it into the intervertebral space. 6. Perform auxiliary fixation using spinal screws and rods or plates, place a drainage tube, and routinely suture the incision. 7. Postoperatively, the patient should wear a brace and undergo rehabilitation in collaboration with the doctor. |

随机方法(请说明由何人用什么方法产生随机序列): |
本试验采用分层随机方法,以临床试验机构和治疗部位(胸腰椎和颈椎)为分层因素,采用基于网络的中央随机系统(即基于网络的交互式网络应答系统,Interactive Web Response System,IWRS),对筛选合格的受试者进行随机分组,随机分组时间为签署知情同意且通过入组筛选后。随机化分组保证了除处理因素外,其他可能产生混杂效应的非处理因素在各组中尽可能保持一致,以保持各组的均衡性;1:1 的随机化分组保证了每位受试者都有同等的机会被分配到试验组或者对照组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This trial uses a stratified randomization method, with clinical trial sites and treatment sites (thoracolumbar and cervical spine) as stratification factors. A web-based central randomization system (i.e., Interactive Web Response System, IWRS) is used to randomly assign eligible subjects. Randomization occurs after signing the informed consent and passing the enrollment screening. Randomized grouping ensures that, apart from the treatment factor, other non-treatment factors that may cause confounding effects are kept as consistent as possible across groups to maintain group balance. A 1:1 randomization ratio ensures that each subject has an equal chance of being assigned to the experimental group or the control group. |
