Emerging treatments
Pulsed radiofrequency
Pulsed radiofrequency involves the creation of a controlled radiofrequency electrical field around a nerve, without causing significant tissue destruction by avoiding temperatures above 107.6°F (42°C). This technique has been reported in the treatment of coccygodynia through a caudal epidural approach to S3-S4. Of 21 patients treated, 81% had good or excellent outcomes at 6 months post-treatment.[42] This technique has also been used to target the ganglion impar.[43]
Extracorporeal shock wave therapy
Extracorporeal shock wave therapy can be used to treat painful musculoskeletal disorders. In one study 34 patients (29 females, 5 males) were treated once a week for chronic coccygodynia with variable numbers of sessions. After 6 months, the visual analog scale score decreased to ≤3 in 79.4% of patients.[44]
