Objective:
We conducted an open observational study to assess the short and longterm effect of single local glucocorticosteroid injection for trochanteric bursitis.
Methods:
75 patient diagnosed with trochanteric bursitis based on clinical criteria were injected; 20, 32, and 22 patients each received 6, 12, and 24 mg betamethasone, respectively, mixed with 4 cm3 of 1% lidocaine. A standardized baseline questionnaire was administered to assess the severity and functional limitation due to trochanteric pain, including the visual analog scale for pain. Patients were followed at Weeks 1, 6, and 26 to determine their response to treatment.
Results:
77.1, 68.8, 61.3% of responding patients reported improvement in pain at Week 1, 6, and 26, respectively. Patients receiving higher doses of betamethasone were more likely to experience pain relief (p < 0.0123).
Conclusion:
Corticosteroid and lidocaine injection for trochanteric bursitis is an effective therapy with prolonged benefit.
