Hallux rigidus and hallux valgus are chronic forefoot conditions associated with pain, inflammation and functional impairment. Topical cannabidiol (CBD) cream has been shown to decrease inflammation, swelling, and pain response in arthritis models with minimal side effects, although the intervention has never been studied in hallux valgus or hallux rigidus. The purpose of this study is to determine if topical CBD cream is an effective treatment for pain secondary to hallux rigidus and hallux valgus.

Registry facts
Hallux rigidus and hallux valgus are chronic forefoot conditions associated with pain, inflammation and functional impairment. While operative interventions exist, nonoperative modalities are the mainstay of treatment for most patients. Options include shoe wear modification, manual and physical therapy, intraarticular injection of corticosteroids or sodium hyaluronate, oral nonsteroidal anti-inflammatories, and foot orthoses. Oral anti-inflammatories are the most effective non-operative strategy, but unfortunately, are associated with major adverse side effects and are contraindicated in many patients. Topical cannabidiol (CBD) cream has been shown to decrease inflammation, swelling, and pain response in arthritis models with minimal side effects, although the intervention has never been studied in hallux valgus or hallux rigidus. This prospective randomized trial will compare topical CBD cream vs placebo cream for the treatment of pain secondary to hallux valgus and hallux rigidus. The primary outcome of interest in the change in pre and post-treatment Visual Analog System (VAS) pain scores. VAS pain score is a measurement on a continuum of values of pain intensity. The purpose of this study is to determine if topical CBD cream is an effective treatment for pain secondary to hallux rigidus and hallux valgus.

Interventions
Patients will receive Mg-CBDa (magnesium-cannabidiolic acid) cream for topical treatment of hallux rigidus or hallux valgus.
Patients will receive placebo cream (neutral emollient containing no active agent) for topical treatment of hallux rigidus or hallux valgus. The ingredients of the placebo cream are as follows: Butyrospermum parkii (shea butter), caprylic/capric triglycerides medium-chain triglycerides (MCT oil), food coloring to match the CBD oil. There will be 345 grams of shea butter and 62ml MCT oil per batch.

Weekly visual analog system (VAS) pain scores will be measured daily for four weeks. The VAS pain score is a measure of pain severity. It is measured on a scale from 0 to 10, with 10 being the worst pain the patient has experienced. No patients completed full enrollment so no data was analyzed.
Population: No data were analyzed for this outcome because there were no participants data collected.
The foot function index (FFI) is a questionnaire that measures foot pain and disability. It is self-administered and consists of 23 items divided into 3 subscales (pain, disability, and activity limitation). The pain subcategory consists of 9 questions (scored out of 90) and is a measure of pain in different situations, such as walking with shoes versus barefoot. The disability subcategory consists of 9 questions (scored out of 90) and measures functional activities, such as difficulty walking upstairs. The activity limitation subcategory consists of 5 questions (scored out of 50) and measures limitations caused by the foot problem. All three subcategories are summed together to get a final number, with higher numbers indicating worse pain.
