Comparative Study Between Conventional Radiofrequency Ablation vs Chemical Neurolysis of Ganglion Impar for Treatment of Chronic Non Cancer Related Coccydynia

• Status: Active Not Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 74 (estimated)
• Sponsor: Ain Shams University · Academic / Other
• Sex: All
• Age: 20 Years – 70 Years
• Healthy volunteers: Not accepted

Summary

Aim: compare effectiveness (satisfaction) and duration of pain relief between patients who perform the conventional thermal radiofrequency on the ganglion impar vs patients who perform the chemical neurolysis with alcohol in patients with non cancer coccydynia patients with non cancer coccydynia not responding to medical treatment will be divided into 2 groups before intervention , control group will receive conventional radiofrequency ablation of ganglion impar , while the study group will receive alcohol neurolysis

Conditions

• Pain Management

Interventions

Type	Name	Description
PROCEDURE	Radiofrequency ablation alone	The entry site was detected under fluoroscopy then local anesthesia was given using lidocaine 2% followed by the insertion of a radiofrequency cannulas (STRYKER 20 G, 9 cm with 1 cm active tip) targeting the junction between the coccygeal bones and pass through it anteriorly in the lateral view. Finally confirming the proper site with a contrast dye in lateral and A-P views. 10 ml of lidocaine 1 % was injected to tolerate the ablation then in the 1st group placing of the radiofrequency cable followed by ablation will be done at 80 degrees for 90 seconds.
PROCEDURE	Alcohol injection	The entry site was detected under fluoroscopy then local anesthesia was given using lidocaine 2% followed by the insertion 22 G spinal needle targeting the junction between the coccygeal bones and pass through it anteriorly in the lateral view. Finally confirming the proper site with a contrast dye in lateral and A-P views. 10 ml of lidocaine 1 % was injected to tolerate the ablation then injection of 5 ml 70% alcohol will be performed
