Fluoroscopic-Guided Hydrodilatation Offers Significant Relief for Frozen Shoulder, Prospective Study Finds
Prospective research shows minimally invasive hydrodilatation substantially reduces pain, restores shoulder function and improves emotional well-being in patients with adhesive capsulitis.
A prospective clinical study has found that fluoroscopic-guided hydrodilatation is an effective minimally invasive treatment for frozen shoulder, providing significant improvements in pain, shoulder mobility and overall quality of life. The procedure, performed under real-time X-ray (fluoroscopy) guidance, stretches the tightened shoulder capsule by injecting saline, local anesthetic and corticosteroid directly into the joint.
Researchers evaluated patients before treatment and again at one and three months using validated outcome measures, including the Visual Analog Scale (VAS) for pain, the Disability of the Arm, Shoulder and Hand (DASH) score, the Shoulder Pain and Disability Index (SPADI), and the Hospital Anxiety and Depression Scale (HADS). The study demonstrated statistically significant improvements across all clinical assessments following the procedure.
Pain levels declined markedly during follow-up, with the average VAS score falling from 7.6 before treatment to 3.1 after three months. Functional disability also improved substantially, as DASH scores dropped from 70.2 to 35.3, while SPADI scores decreased from 74.5 to 39.2, reflecting better shoulder movement and reduced daily limitations.
Beyond physical recovery, the study highlighted important psychological benefits. Patients reported significant reductions in anxiety and depression symptoms as pain decreased and shoulder function improved. Researchers noted that restoring mobility enabled patients to resume normal daily activities, contributing to better overall mental well-being.
The procedure was well tolerated, with no major complications reported during the study period. Investigators concluded that fluoroscopic-guided hydrodilatation offers a safe alternative for patients whose symptoms persist despite conservative treatments such as pain medications, physiotherapy and corticosteroid injections alone.
Frozen shoulder, or adhesive capsulitis, affects approximately 2–5% of the general population and is particularly common among adults aged 40–60 years, especially those with diabetes or thyroid disorders. The condition is characterized by progressive pain, stiffness and restricted shoulder movement, often lasting many months if left untreated.
Orthopedic specialists note that hydrodilatation works by mechanically stretching the contracted joint capsule while delivering anti-inflammatory medication directly into the shoulder. When combined with structured physiotherapy, the technique can accelerate recovery and improve long-term shoulder function. Experts emphasize, however, that larger randomized controlled trials are still needed to compare fluoroscopic-guided hydrodilatation with ultrasound-guided procedures and other established treatment options.
