Symptomatic sacrococcygeal joint dislocation treated using closed manual reduction: A case report with 36-month follow-up and review of literature

Dislocation of the sacrococcygeal joint is a rare injury from trauma to the buttocks, most often from falling backwards. Standard of care for this injury has not been determined because it is rare. Left untreated this can cause coccydynia in the long-term. Here we present a case report to describe the treatment of an anterior sacrococcygeal dislocation with closed manual reduction. A 13-year-old female presented to the emergency department with buttock pain after slipping backwards down the stairs. On X-ray the coccyx was in bayonette apposition to the anterior distal sacrum and shortened by 6 mm. To manage the injury, closed manual reduction of the sacrococcygeal joint was performed. To our knowledge, this is the first successful case of sacrococcygeal dislocation treated with closed manual reduction, resulting in complete relief of symptoms at 36 months follow-up. Sacrococcygeal dislocations can be treated with closed manual reduction, resulting in lower morbidity and faster recovery compared to surgical treatment.
