Abstract
Introduction: Trochanteric bursitis is a common hip problem that can be refractory to treatment. The available modalities of treatment can be less effective. We evaluated the use of extra-corporeal shockwave therapy treatment for trochanteric bursitis.
Methodology: 22 patients with the clinical and radiological (in 6 patients) diagnosis of trochanteric bursitis were treated in a dedicated shockwave therapy clinic using Swiss dolocast radial shockwave therapy machine. 3 sessions of treatment were given one week apart, delivering 2000 impulses at 10 Hz at each session. Patients were evaluated prior to treatment, 3 months, 6 months and 12 months following their treatment. The visual analogue score (VAS) was used in all patients pre and post treatment. Hip disability and osteoarthritis score (HOOS) was performed post-treatment.
Results: Between December 2005 and November 2008 22 patients were treated for symptoms of trochanteric bursitis. There were 17 women and 5 men. The average age was 55.8 years (range 33–76 years). 6 patients had proven increase signal on MRI scan the rest were mainly clinical diagnosis and after a limited response to steroid injections. Their VAS improved from 10 to 5. Their post-treatment HOOS score averaged 255.
Of the 6 patients who had MRI proven increased signal 5 patients had significant improvement. The average improvement in the VAS was 10 to 2.3 and their HOOS scores were 349.2 (range 427–243).
Conclusion: Though the number of patients in this study is only 22 it seems that radial shockwave therapy treatment for trochanteric bursitis is promising, especially on those who have got high signal on MRI scans.
