Best treatment for trochanteric bursitis

The short version: the best evidence points to shockwave therapy or structured home exercise as the most durable options, while steroid injections give fast relief that fades and may worsen the long-term picture.

The 2009 Rompe trial that directly compared the three main options for greater trochanter pain syndrome is the most informative single study here [1]. At one month, corticosteroid injections looked like a miracle: 75% success, pain down to 2.2 out of 10. Shockwave therapy managed only 13% success, and home training just 7%. But by four months the picture had flipped. Shockwave reached 68% success, home training 41%, and the steroid group had already dropped to 51%. By fifteen months, home training led at 80% success, shockwave was close at 74%, and the steroid group had fallen to 48% — worse than doing nothing at home [1]. The steroid group's pain score at 15 months was actually higher than at 4 months, suggesting the initial relief came at a cost.

The 2016 narrative review confirms that what doctors call "trochanteric bursitis" is usually a gluteal tendon problem, not a bursa problem [2]. Ultrasound studies of 877 patients with lateral hip pain found gluteal tendinosis in half of them, while isolated trochanteric bursitis was present in only 20% [2]. That matters because injecting steroid into a degenerating tendon is known to increase rupture risk. The review also cites a 2009 trial of shockwave therapy for GTPS that reduced pain from 8.5 to 2.7 at 12 months, and a small PRP case series where 81% reported moderate or better improvement at 15 months [2]. A 2024 pilot study of combined focused and radial shockwave for gluteus medius tendinopathy reported 91% treatment success at the first follow-up, with improvements lasting about 26 months and no adverse events [4].

The 2022 natural history study of 58 patients followed for about six years is worth noting: most partial tears stayed stable, and nonoperative management produced functional outcomes comparable to published surgical results [5]. That suggests surgery is rarely needed.

The evidence is moderate quality. The Rompe trial is the only head-to-head comparison with long follow-up, and it was not funded by a device manufacturer. The pattern is consistent across other tendinopathy sites: steroid gives quick relief but the benefit erodes, while mechanical treatments like shockwave and exercise produce slower but lasting improvement. The mechanism fits — steroid suppresses inflammation temporarily but impairs tendon healing, while shockwave stimulates blood flow and collagen remodeling through mechanotransduction [3].

My call: structured home exercise or radial shockwave therapy, not steroid injection. Confidence: moderate.
