Morphometric evaluation of coccyx in patients with coccydynia and classification

Abstract

Aim: This study aimed to aimed to classiffication the morphological and pathological anatomic features of patients with coccydynia.Patients and Method: Patients over 16 years of age who were admitted to Alanya Alaaddin Keykubat University Educational Research Hospital with complaints of coccydynia between April 2015 and April 2018, were included in the study. The sitting and standing coccyx and anterior-posterior pelvic radiographs of the patients were examined retrospectively.Results: It was observed that coccyx scoliosis, hypermobility, and dislocation were unrelated to sacrococcygeal angulation. There was a positive correlation between sacrococcygeal and intercoccygeal angles in the measurements of sitting and standing coccyx radiographs of the patients. There was a correlation between the length of the sacrum and length of the coccyx and also the intercoccygeal angle and coccyx length in the unoperated patients. There was a positive correlation between length of the sacrococcygeal joint and sacrococcygeal angle in males. Fusion in the sacrococcygeal joint was less in females. Conclusion: In the evaluation of patients with coccydynia, it should not be forgotten that the coccyx is a spinal segment which can move in all planes and develop pathology. Side and AP positioned sitting and standing dynamic radiography is an effective method for the detection of pathology in this patients. New classification including pathology in all three planes is needed in the classification of patients with coccydynia. We believe that our classification will eliminate this deficit.
