Purpose: This study examined the clinical outcomes and usefulness of triamcinolone acetonide (TA) injections as an option in the conservative treatment of patients with lateral malleolar bursitis of the ankle.
Materials and Methods: A total of 27 patients (27 ankles), in whom TA injection had been performed between March 2016 and June 2017, were reviewed retrospectively. After the aspiration of fluid in the lateral malleolar bursal sac, 1 mL (40 mg) of TA was injected into the malleolar bursal sac. After the injection, the ankle was compressed with an elastic cohesive bandage for 2 to 4 weeks. The clinical outcomes and side effects were evaluated at the following time points: 2 weeks, 4 weeks, 3 months, 6 months, and 1 year after TA injection therapy. The responses to treatment were assessed according to the degree of fluctuation, shrinkage of the bursal sac, and soft tissue swelling.
Results: The mean age was 62.1 years (range, 41∼81 years); there were 19 males and 8 females. Complete resolution was observed in 26 patients (96.3%) after the first or second application of a TA injection, and a partial response was observed in 1 patient (3.7%) after the first TA injection. The physical component scores of Medical Outcomes Study 36-item Short-Form Health Survey improved from 71.1 to 76.0 at the last follow-up (p=0.001). Associated complications were 1 patient (3.7%) with skin atrophy and 3 patients (11.1%) with transient hyperglycemia in diabetes mellitus.
Conclusion: TA injection is a useful and safe procedure for patients not responding to the usual conservative treatment of lateral malleolar bursitis of the ankle.
