Anatomic and morphometric evaluation of the coccyx in the adult population
Öz
Background: To evaluate the sacrococcygeal anatomy and morphometry with lower abdomen magnetic resonance (MR) images in asymptomatic adult subjects
Methods: We retrospectively reviewed the images of 216 adult patients who underwent MR imaging of the lower abdomen for reasons other than coccydynia in the radiology clinic. In this evaluation, coccyx (Co) thickness (from Co1 middle section), sacrococcygeal angle, fusion between vertebrates, number of coccygeal vertebrae, sacrococcygeal joint angle, intercocsigeal joint angle, coccyx type, presence of subluxation, coccyx flat length, coccyx curvature length, sacrum flat length, sacrum curvature length, sacrococcygeal flat length,
sacrococcygeal curvature length, sacral angle, coccyx curvature index, sacrum curvature index, sacrococcygeal curvature index were measured.
Results: The mean number of coccyx vertebrae was 3.5 ± 0.75 in females and 3.8 ± 0.78 in males. The mean coccyx thickness was 7.3 ±1.4 mm in females and 8.4±1.8 in males. Subluxation was determined in 59 (27.3%) cases, and not in 157(72.7%) cases. The mean length of the coccyx was 35.4±6.6 mm in females and 38.9±8.7 mm in males. The mean length of the coccyx curvature was 37.5±7.2 mm in females and 41.7±9.1 mm in males.
The most common coccyx type in both males and females was type II coccyx in 98 (45.4%) patients. The sacrococcygeal angle was 109±15 degrees in females and 113±13 in males.
Conclusion: Knowledge of the vertebrae anatomy of asymptomatic patients may prevent unnecessary surgery in coccydynia. Wide ranges of similar studies are needed to be done with patients with coccydynia.
