Abstract

Background: the aim of this study was to measure the effects of high volume image-guided injections and structured rehabilitation (HVIGI&SR) for greater trochanter pain syndrome (GTPS).

Methods: 31 consecutive subjects were recruited (23 retrospectively; 8 prospectively) over 5 months. GTPS was diagnosed based on history and examination findings, alongside radiological examination. The HVI-GI used a 22-gauge spinal needle to administer 10ml of 0.5% Marcaine and 50 mg hydrocortisone just deep to the periosteum underlying the gluteal tendon insertion under ultrasound guidance, followed by structured rehabilitation. A visual analogue scale (VAS) for pain was used as the main outcome measure.

Results: the mean VAS improved from 81.7 mm (±17.6) to 42.3 mm (±28.3), (p<0.05) in the prospective subjects at a mean of 6 weeks, considered clinically significant. In the retrospective subjects the mean VAS had improved from 74.6 (±10.9) mm to 38.2(±31.2) mm at two weeks (p<0.01) and 31.3 (±27.6) mm at the final time point, a mean of 60 weeks (p<0.01). The Hip and Groin Outcome Score in the prospective group showed a non-significant increase from 173.2 to 296.1 (p=0.12).

Conclusion: HVIGI&SR should be considered when short- and medium-term pain-relieving treatment for GTPS is required. Controlled studies are warranted to fully establish effectiveness, and assess long term effects.

Level of evidence: case series.

Keywords: VAS scale; greater trochanter pain syndrome; injection; ultrasound.
