Chiari Malformation Clinical Trial
Official title:
Clinical Study of Atlanto-occipital Decompression Lateral Joint Release Combined With Occipital-neck Fusion in the Treatment of Chiari Malformation Combined With Type II Skull Base Depression
The research background of this study is that Chiari malformation (CM) is a congenital malformation in the foramen magnum region, often associated with syringomyelia, basilar depression, odontoid dislocation and other craniocervical junction deformities. The traditional surgical method for Chiari malformation with skull basilar depression is simple decompression without fixation, so it cannot effectively maintain the stability of the cervical spine and reduce the compression of the brainstem and cervical cord, often resulting in poor curative effect and aggravated symptoms. The cervical spine is the most flexible and most mobile part of the spine, and the instability of the cervical spine will directly affect the quality of life of patients after surgery. Subsequently, with the continuous advancement of technology and the continuous development and improvement of surgical methods, Investigators can relieve spinal cord compression by using atlanto-occipital decompression and dissection followed by C1/2 lateral arthrolysis combined with occipitocervical fusion. So, is this surgical combination the most effective surgery for patients with Chiari malformation and type II skull basilar depression? How should doctors adjust to the best surgical approach to treat patients with Chiari malformation and type II skull basilar depression? These questions have long puzzled neurosurgeons. By conducting this research, investigators hope that participants can participate in it, and work with them to answer this question, and jointly promote the development and progress of doctors' careers, while benefiting more patients.

Primary | Chang of Chicago Chiari outcome score | The Chicago Chiari Malformation Prognosis Scale (CCOS) is a comprehensive quantitative scoring criterion for surgical prognosis in patients with Chiari malformations, first proposed by the Department of Neurosurgery of the University of Chicago School of Medicine. CCOS covered four scoring criteria, including improvement in pain symptoms, improvement in non-pain symptoms, ability to live, and surgery-related complications, with a single score of 1-4 for a total score of 4 to 16, and at the last follow-up, the higher the patient's score indicated the better the patient's postoperative prognosis. | through study completion, an average of 1 year | |
Secondary | Occurrence of complications | 1)Minor complications such as pain, neck stiffness, and poor wound healing. 2)Serious complications such as vertebral artery injury, dyspnea, cerebrospinal fluid leakage, and severe intracranial infection. | The second week after surgery | |
Secondary | Chang of Magnetic Resonance Imaging | Measurements of radiographic improvement, such as cerebellar tonsillar hernia length. | through study completion, an average of 1 year | |
Secondary | Chang of Visual Analog Score for pain | Visual Analog Score stands for visual analogue scoring method and is one of the commonly used pain scoring criteria. The main thing is to draw a 10cm horizontal line on the paper, the beginning end is 0, the other end is 10, the middle part represents different degrees of pain, let the patient choose the degree of pain by himself. A score below 3 represents mild pain; 4-6 are divided into pain that interferes with sleep, but is tolerable; A score of 7-10 indicates unbearable pain. | through study completion, an average of 1 year | |
Secondary | Chang of Japanese Orthopaedic Association Scores | The patient's lumbar spine function and improvement were mainly evaluated from four aspects: subjective symptoms, daily activity ability, clinical signs, and bladder function. The scoring range is 0~29 points, and the higher the total score, the milder the patient's condition. | through study completion, an average of 1 year | |
Secondary | Chang of Neck Disability Index | Neck Disability Index consists of 10 items, including: neck pain and related symptoms (pain intensity, headache, concentration and sleep) and activities of daily living (personal care, lifting heavy objects, reading, work, driving and playing). Each item has a minimum score of 0 and a maximum score of 5, with higher scores indicating greater levels of dysfunction. | through study completion, an average of 1 year |
