Coccydynia

Coccydynia is used to describe coccygeal pain or pain affecting the tailbone region.1 The exact incidence of coccydynia is unknown, but it is more prevalent among females as well as obese patients. Other etiologies include trauma, infection, neoplasms, and degenerative disease. The pain is typically worse with prolonged sitting, standing, or moving from a sitting to a standing position. Diagnosis is based on clinical assessment with a focused history and physical exam. Dynamic films, including lateral radiographs, can help aid in the diagnosis by highlighting coccygeal mobility, fusion of the sacrococcygeal and superior intercoccygeal joints, osteolytic lesions, fractures, osteoarthritis, subluxation, and pelvis rotation. The majority of patients with coccydynia can be treated with conservative measures. When conservative treatments fail, interventional treatment can be considered, which range from minimally invasive procedures to surgery.
