Description

Chronic coccydynia is a multifactorial pain syndrome affecting the coccygeal region and is often associated with trauma, prolonged sitting, obesity, or idiopathic causes. Patients frequently report severe localized pain that worsens with sitting and transitions from sitting to standing. Conservative treatment options include physical therapy modalities and manual therapy techniques, while interventional procedures such as ganglion impar block are commonly used in refractory cases.

This prospective randomized controlled trial aims to compare the clinical effectiveness of osteopathic manual therapy and ganglion impar block in patients with chronic coccydynia. Eligible patients will be randomly allocated into two groups. The osteopathic manual therapy group will receive standardized manual therapy sessions targeting pelvic alignment, sacrococcygeal mobility, and surrounding soft tissue structures. The ganglion impar block group will undergo fluoroscopy-guided ganglion impar injection performed under sterile conditions.

Primary outcome measures will include pain intensity assessed by the Numeric Rating Scale (NRS). Secondary outcomes will include functional disability assessed by the Oswestry Disability Index (ODI). Assessments will be performed at baseline, week 3, and month 3 follow-up.

The study is conducted at Medicana Zincirlikuyu Hospital in collaboration with Istanbul Atlas University. Ethical approval has been obtained from the Istanbul Atlas University Clinical Research Ethics Committee. The findings of this trial will contribute to the evidence base regarding non-surgical management options for chronic coccydynia.
