Brief Summary
This study is a randomized controlled trial, assessing the effect of a single platelet rich plasma (PRP) injection in post traumatic (concussive) greater occipital neuralgia. This study will compare the effects of a single PRP injection to injection with steroid and anesthetic. There will also be a third arm to the study, in which patients will receive an injection with normal saline. This study will assess the severity and frequency of headache symptoms before and after receiving the injection.

Outcome Measures
Primary Outcomes (2)
Evaluate the feasibility of platelet-rich plasma for patients with post-traumatic greater occipital neuralgia
The feasibility will be determined based on recruitment (greater than 30% of those screened eligible), attendance (70% intervention appointment attendance), retention (70% complete study protocol), and the acceptability of the protocol
Screening, pre-injection to 3-months post injection
Evaluate the safety profile of platelet-rich plasma for the treatment of post-traumatic greater occipital neuralgia
Safety will be determined based on adverse reactions monitored through daily headache diary reporting and communication with the study team
from immediately post-injection to 3-months, daily recording
Secondary Outcomes (4)
Change in headache severity as measured by the Numerical Pain Raiting Scale (NPRS)
Pre-injection to 3 months post injection, daily recording.
Change in headache frequency (days per month with headache).
Pre-injection to 3 months post injection, daily recording.
Headache Impact Test-6
Pre-injection, 1 month, and 3 month time points.
Quality of Life in Following Brain Injury Questionnaire
Pre-injection, 1 month, and 3 month follow-ups.
Study Arms (3)
Autologous Platelet Rich Plasma Injection
EXPERIMENTALPRP contains high concentrations of platelets, growth factors, and anti-inflammatory molecules.
Standard Treatment
ACTIVE COMPARATORSteroid and anesthetic injection: the clinical standard.
Normal Saline
PLACEBO COMPARATORPlacebo injection, with no known treatment effects.
Interventions
60mL of blood will be drawn from the antecubital vein and processed via centrifugation. Samples will be centrifuged as per manufacturer instructions, yielding 5mL of PRP.
Steroid injections will be prepared to include 20mg Depo-Medrol and 2mL 2% lidocaine.
Eligibility Criteria
You may qualify if:
- Eligible participants will be males or females at least 18 years of age who suffer from post-traumatic headaches secondary to GON. Patients must fulfill the ICHD-3 criteria in establishing a diagnosis of GON. This diagnosis will be established by an experienced Physiatrist with extensive experience in headache and related disorders. To meet this criteria, patients must have experienced previous successful temporary relief with local anesthetic or steroid injection surrounding the GON in the past, but have not received local steroid injection within past 3 months. Pre-treatment numerical pain rating scale for daily headache intensity must be ≥4/10, with a headache frequency ≥10 days/month. Possible secondary causes of ON must be ruled out with reasonable level of investigation prior to enrollment.
You may not qualify if:
- Inability to provide informed consent; history of surgery in the occipital region; unstable psychiatric or medical condition; rheumatologic or inflammatory disorders; widespread neurologic disorders (eg. MS); coagulopathy; immunosuppression; active cancer; herpes zoster infection in last 6 months; pregnancy; steroid or other local GON or LON infiltration in past 3 months.
