Abstract

AIM:

To evaluate the pelvic incidence (PI) of coccydynia patients treated by different methods and to determine whether it is a risk factor or a prognostic factor.

MATERIAL AND METHODS:

Patients who were treated for coccydynia were evaluated retrospectively, and 110 patients were enrolled. Spinopelvic parameters were measured by using Surgimap software, and the position of the coccyx was evaluated according to the Postacchini classification. The results were compared to spinopelvic parameters of healthy population.

RESULTS:

The mean PI of the coccydynia patients did not differ from the healthy population, and there were no differences between treatment subgroups. The Postacchini classification showed that patients with type-3 and type-4 configurations had higher PI. When treatment groups were evaluated according to Postacchini classification, 80% of the surgery group had type-3 and type-4 configurations (50%, 30% respectively).

CONCLUSION:

This is the first study to evaluate the PI of coccydynia patients. Patients with higher PI were prone to having type-3 of type-4 coccyx configurations and undergoing surgical treatment.
