CD is most often idiopathic, however, in a small number of patients, CD occurs within one day to one year after mild to severe trauma. This type of CD is further classified as posttraumatic CD. OnabotulinumtoxinA (Botox) injections are considered to be a controversial treatment for posttraumatic CD and have produced variable result. This report describes the case of a 32-year-old female presenting with a two year history of posttraumatic CD and associated head, neck, and shoulder pain after obtaining a severe head injury during a motorcycle accident. OnabotulinumtoxinA was used to successfully treat her posttraumatic CD muscle spasms and associated chronic pain. Three months after her first and second ONA treatments, the patient reported at least 50% improvement in her overall pain symptoms and a noticeable reduction in cervical paraspinal muscle spasms.展开更多

It is associated with severe pain in the greater, lesser, and/or third occipital nerves, and often accompanied by tenderness or trigger points in the surrounding musculature. OnabotulinumtoxinA (ONA) has been recently utilized in nerve blocks to treat occipital neuralgia, but current literature supporting such use is scarce. We describe a case of occipital neuralgia in a patient following C1 fracture and vertebral artery dissection due to gunshot injury. Successful treatment with bilateral ONA nerve blocks led to an 80% - 90% improvement in pain, with decreased Visual Analog Scale (VAS) pain scores immediately following treatment and upon follow-up 1 month later.展开更多

Occipital neuralgia is typically idiopathic, but also is characterized as a common form of posttraumatic headache. Typical treatments include nerve blocks with local anesthetic, nerve stimulation, pulsed radiofrequency, and cryoablation. OnabotulinumtoxinA (ONA) has recently been utilized in nerve blocks to treat occipital neuralgia, with the potential for a longer duration of pain relief than local anesthetic. Our study retrospectively examined 63 patients treated for occipital neuralgia, including 19 with ONA. 80 - 155 units of ONA were administered bilaterally in the surrounding musculature. A total of 61 patients, including 17 of those subsequently treated with ONA, were treated with local anesthetic, using a 1:1 mixture of 0.25% bupivacaine and 1% lidocaine, plus triamcinolone. Patients reported VAS pain scores before and after their procedures, and again during 4-week follow-up visits. Information on opioid use, overall pain relief, and duration of full relief was also recorded upon follow-up. Patients treated with ONA exhibited significant decreases in average VAS pain scores from 4.1 ± 2.6 pre-procedure to 2.1 ± 2.4 post-procedure (p = 2 × 10<sup> -5</sup>), and 3.0 ± 2.5 4 weeks later (p = 0.0234). Mean overall relief was 75.8% ± 25.0%. Treatment with local anesthetic suggested equally efficacious reduction of VAS scores;however, treatment with ONA showed a significantly higher percentage of overall pain relief leading to follow-up. Opioid use did not exhibit significant change, regardless of treatment type. Our results support the hypothesis that use of Onabotulinum-toxinA in occipital nerve blocks leads to significant decreases in pain, while possibly exhibiting a longer duration of action than that of local anesthetic.展开更多
