Trochanteric bursitis is a common cause of musculoskeletal pain and often requires medical intervention and should be distinguished from sciatica and irradiating pain of pelvic and spinal origin. Previously, the etiology of the trochanteric pain syndrome was thought to be caused by inflammation. The current study was performed in order to assess the efficacy of trochanteric injections. Methods: 158 patients were treated for trochanteric bursitis (132 females/26 males, range 22 - 88 years). 59b were treated with corticosteroid injection, 60 with hyaluronate and 39 were injected using a combination of both. Patients were followed by the HOOS score for a minimum of 12 months. Results: Pre-operative HOOS scores were similar in all groups. Following injection, the HOOS score increased from 27 ± 4 to 66 ± 2 after six months and 77 ± 4 after a year. At 12-month follow-up, the average score of patients treated by corticosteroids injection was 44 ± 7 compared with 62 ± 8 for the hyaluronate injected group and 64 ± 6 for the combination injection group. Discussion: It appears that injection therapy is highly efficacious for treating trochanteric bursitis. The effect of hyaluronate or hyaluronate and steroid combination appears to be longer lasting than that of steroid alone.
