“…Fluoroscopy X-rays can be used to guide and confirm needle placement, with or without the use of contrast media [116,117]. Careful patient positioning before the procedure facilitates patient comfort and safe and efficient access to the joint -for the 1 st MTPJ a supine position is appropriate, with a bent knee to allow the foot to rest flat on the table or radiography sensor [118].…”

Introduction: Therapeutic injections provide a treatment option for patients with joint and periarticular pain, those who are not surgical candidates, whom conservative treatment has failed, or those that are awaiting surgery. Injectable glucocorticoids are one of the most common therapeutic interventions in musculoskeletal healthcare and are widely used in pathologies of the first metatarsophalangeal joint. The aim of this paper is to highlight current concepts around first metatarsophalangeal joint injection injection accuracy.
Anatomy: The first metatarsophalangeal joint is a condyloid synovial juncture and consists of the head of the first metatarsal, the base of the proximal phalanx, six muscles, eight ligaments and two sesamoid bones, with associated ligamentous attachments. The joint capsule is shaped like a box.
Methods: To achieve the research aim, a scoping review was undertaken with a search strategy that identified evidence via the following sources: Electronic databases, Google scholar, and Reference lists.
Results: The search yielded 193 articles, 48 of which appeared of potential relevance. After removing duplicate articles this total was reduced to 37 articles. After scanning the content, 27 were excluded to leave 10 articles. Twenty eight further articles were found through related author research, examination of reference lists and free text searches of Google Scholar. One reference was unobtainable. The final count of papers utilised for review was 37 which produced three themes, one of which was injection accuracy.
Injection accuracy: In the long history of injection therapy, infiltrations have often been performed without image guidance, i.e., using palpation guidance, anatomical landmarks and clinical judgement to direct needle entry and advancement. Needle placement may also be confirmed by use of diagnostic imaging. Typical imaging modalities are fluoroscopy or ultrasound, used alone or in combination with contrast media.
Discussion: The perceived wisdom is that if an injectate misses its target it is likely to be less effective and lead to false negative reporting of poor treatment outcomes, but the literature is not equivocal. This article discusses the recent literature in the field.
Conclusions: The literature suggests that steroid injections are safe and effective for the short-term relief of joint pain. When injecting small synovial joints using palpated-guided methods, clinicians must be alert to the potential for failure of technique from the needle penetrating too far into the articulation and exiting the joint on the contralateral side from the entry point. Use of shorter needles and use of imaging, +/- the use of contrast media, might reduce the number of such failures.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
