Background: The two most common diseases affecting the first metatarso-phalangeal joint (1st MTP jt) of the foot are hallux limitus/rigidus (osteoarthritis) and hallux valgus (bunion), but other pathologies also affect the region. There are a range of treatments for these conditions: one treatment option is intra articular injection therapy, and this is one of the most common therapeutic interventions in musculoskeletal healthcare. Therapeutic injections of corticosteroids provide a treatment option for patients with joint or peri-articular pain, those who are not surgical candidates, in those in whom conservative treatment has failed or for those awaiting surgery. They are accepted as an important treatment modality, but currently there are no evidenced-based guidelines about administration technique or regimen of the 1st MTP jt. This is a scoping review protocol for the study to identify key concepts in intra-articular corticosteroid injections for pathology of the first metatarsophalangeal joint.Methods and analysis: Scoping reviews are used to assess and understand the extent of the knowledge in an emerging field or to identify, map, report, or discuss the characteristics or concepts in that field. The Joanna Briggs Institute (JBI) is an international research organisation based in the Faculty of Health and Medical Sciences at the University of Adelaide. The JBI develops and delivers evidence-based information, software, education, and training and its guidance is widely cited across a range of disciplines, academic fields, and professional backgrounds. This scoping review will follow the JBI process who recommend the PCC framework (‘Population–Concept–Context’) to frame the research question. The ‘Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Reviews’ will be used to guide the reporting of this protocol and will also subsequently be used to structure the reporting of the full review (PRISMA-ScR). Dissemination: Findings will be presented to explore speciality-specific and profession-specific commonalities and differences. The scoping review results will be disseminated via publication in peer-reviewed journals (it is envisaged that at least two publications will be developed) and presentation at national/international conferences.
