Landmark-Guided Dextrose Prolotherapy for Coccydynia: A Retrospective Study
Sponsor: Gaziosmanpasa Research and Education Hospital
Summary
Coccydynia is a musculoskeletal pain condition that can lead to chronic pain and functional impairment, significantly affecting quality of life. Although conservative treatment is effective in many cases, the number of patients with refractory symptoms appears to be increasing, highlighting the need for effective and accessible treatment options. Prolotherapy is a regenerative injection therapy that aims to stimulate tissue healing and reduce pain through the modulation of nociceptive signaling, most commonly using dextrose solutions. This retrospective study aims to evaluate the effectiveness of landmark-guided (blind) dextrose prolotherapy in reducing pain and improving functional status in patients with mechanical or idiopathic coccydynia. The study includes patients who underwent prolotherapy to coccygeal ligaments between January 1, 2024, and June 1, 2025, with a treatment protocol consisting of 3-6 sessions administered at 3-week intervals using a 15% dextrose solution.

Dextrose prolotherapy
Landmark-guided (blind) prolotherapy was performed using a 15% dextrose solution under sterile conditions. The procedure was carried out based on anatomical reference points without ultrasound guidance. The coccygeal and sacrococcygeal ligamentous structures were targeted, and injections were administered to 3-4 periosteal insertion points using a 27G needle. A maximum of 0.5 mL was injected per site, with a total volume not exceeding 2-2.5 mL per session. The treatment protocol consisted of 3 to 6 sessions performed at 3-week intervals.
