Introduction: Injections are used to treat a wide variety of pathologies. Our aim was to evaluate the efficacy and safety of foot and ankle injections in our clinic.

Materials and methods: We performed a retrospective review of notes and a telephone questionnaire audit into the clinical outcome of all patients who underwent an injection of the foot or ankle in a year. All procedures were performed in an out-patient setting by a consultant musculoskeletal radiologist using either ultrasound or X-ray guidance, with a minimum of two year follow-up. According to the pathology treated, the type of injection included depomedrone, hyaluronic acid and high volume saline injections.

Results: Overall 410/446 (92%) patients reported a significant improvement in symptoms and 227 (62%) reported complete resolution of their pain, with 127 (28%) remaining asymptomatic at two year follow-up. The mode time of recurrence of pain was three months. 59 (13%) underwent a further injection and 102 (23%) underwent operative intervention within the follow-up period. There were no reported infections. Complications occurred in two percent of patients, including steroid flare, pain and plantar plate ruptures.

Conclusion: Injections are a safe and effective option for treating a variety of foot and ankle conditions and reduce the need for surgery. They are particularly effective for the treatment of ankle soft tissue impingement. They appear ineffective in providing significant improvement in pain for longer than three months in conditions such as plantar fasciitis and hallux rigidus.
