Retropharyngeal tendinitis may be more common than we think: a report on 45 cases seen in Danish chiropractic clinics

Abstract

Objective: This study presents information from 45 cases of retropharyngeal tendinitis that were collected in Danish chiropractic clinics.

Methods: A practicing Danish chiropractor collected cases of retropharyngeal tendinitis from colleagues who were members of the Danish Society of Chiropractic and Clinical Biomechanics. Only cases where a patient history of acute severe neck pain, cervical stiffness, and dysphagia were considered, and these were supplemented with imaging in the form of x-rays, computed tomography, or magnetic resonance imaging scans. All cases were reviewed independently by the chiropractor and a medical radiologist with a specialty in musculoskeletal disorders before acceptance into this case series.

Results: Forty-five cases fulfilled the inclusion criteria and were included in this review. Sixteen of these were recruited from a single chiropractic practice. Nineteen were males and 26 were females with an average age of 48 years. All but 2 patients had the characteristic depositions of calcium hydroxyapatite in the tendon of the longus colli muscle, and the average diameter of the retropharyngeal space was 8.1 mm.

Conclusions: Patients presenting with a triad of acute severe neck pan, stiff neck, and dysphagia may have retropharyngeal tendinitis. This condition may be a more common than previously thought among patients presenting with acute neck pain in the primary health care sector.
