Background: Gluteal tendinopathy is a common condition causing lateral hip pain. It is also a common comorbid cause of chronic pain. Hydrodissection, a minimally invasive technique involving injection of fluid to separate fascial layers and release entrapped nerves and tendons, has emerged as a potential treatment. Its use in Gluteal Tendinopathy has not been reported.

Case Description: We present the case of a 67-year-old female with refractory left gluteal tendinopathy confirmed on magnetic resonance imaging (MRI) imaging. Despite extensive conservative therapies, including medications and physical therapy, she continued to experience left lateral hip pain. Intervention: the patient underwent ultrasound-guided gluteal tendon hydrodissection as a targeted approach to address perineural inflammation and nerve entrapment. Hydrodissection of the gluteus maximus and gluteal medius tendons was performed on the left side. A low concentration (5%) dextrose solution was used to free the tendons from surrounding scar tissue and muscle adhesions. The procedure was performed in a theatre setting. Outcome: following the hydrodissection procedure, the patient experienced improvement in lateral hip pain, with sustained improvement over two months when followed up in clinic. Functional outcomes, including range of motion and daily activities, improved substantially. No complications were reported.

Conclusions: This case supports the potential role of dextrose hydrodissection as a safe, minimally invasive treatment option for gluteal tendinopathy. Hydrodissection offers an alternative to more invasive interventions and warrants further investigation in the management of gluteal tendinopathy.
