Treatment of Cervical Intervertebral Disc Herniation by Radio Frequency Target Combined with Collagenase / 昆明医科大学学报

Objective To observe the treatment effect of radio frequency target combined with collagenase in treatment of cervical intervertebral disc herniation. Methods From March 2011 to September 2011, 40 patients with cervical intervertebral disc herniation were divided into 2 groups: Group A and Group B. Patients in Group A were given radio frequency target radiofrequency for treatment of the cervical intervertebral disc herniation and patients in Group B of 20 were given radio frequency target combined with collagenase for treatment of cervical intervertebral disc herniation. Results 40 patients were followed up for 6 months. At the 1st week and 6 months after surgery, the VAS score difference between before and after surgery in patients were compared between two groups by t test. There was no statistically significant difference at the 1st week after surgery between two groups (P>0.05), while 6 months after surgery, there was statistically significant difference between two groups (P<0.05) .Conclusion Radio frequency target combined with collagenase for treatment of cervical intervertebral disc herniation can alleviate the pain symptoms of patients,and the short-term and long-term curative effect is very good. The long-term curative effect has statistically significant difference with pure target radiofrequency ablation treatment. Radio frequency target combined with collagenase for treatment of cervical intervertebral disc herniation has good safety, few side effects, low risks and good short-term and long-term curative effect, so it deserves to be generalized.

Cervicogenic Headache Caused by Cervical C3-C4 Intervertebral Disc Herniation : A case report

Cervicogenic headache is a syndrome characterized by chronic hemicranial pain referred to the head from either bony structures or soft tissues of the neck. Although the pathophysiology and source of pain in this condition have been debated, the pain is believed to be referred from one or more muscles, occipital nerves, facet joints, intervertebral discs, or vascular structures. Among the various possible pain sources, cervicogenic headache from discogenic origin (disc herniation or damaged annulus fibrosus) has been called "discogenic cervical headache". We report a case of cervicogenic headache caused by C3-C4 intervertebral disc herniation. A 33-year-old man presented with headache and posterior neck and right shoulder pain. These symptoms did not improve after therapy with medication, trigger point injection, intramuscular stimulation, greater occipital nerve block, third occipital nerve block, or cervical medial branch block. However, after diagnostic cervical epidural block, the patient's symptoms improved dramatically. Diagnostic magnetic resonance imaging findings confirmed C3-C4 intervertebral disc herniation.

The Evaluation of Curative Effect and Safety Posteolateral Cervical Disc Herniation Discectomy Via Posterior Approach / 医学研究杂志

Objective To investigate the indication,safety and the validity of intervertebral discectomy via posterior approach.Methods There were 8 cases in our group.All received posterolateral intervertebral discectomy and nerve root decompression via posterior approach.The average follow-up period was 5.2 years.The improvement on pain and neurological signs were evaluated.Results Pain disappeared completely in 5 patients and significantly alleviated in the other 3.As to muscle strength and tendon jerk,we observed significant improvement in 6 patients and improvement in the other 2 patients.7 patients got back to their original work and 1 patient shifted to an easy job.No patient had complication.Conclusions Nucleus pulposus removal via posterior approach was a secure and effective one for posterolateral cervical intervertebral disc herniation.
