Brief Summary
The purpose of the study is to analyze the outcomes of patients with coccygodynia (pain in and around the coccyx region) treated with coccygectomy (a procedure during which the coccyx is removed) and to report on the rate of complications of the procedure. The study will also aim to find pre-operative clinical predictors of good outcomes after coccygectomy. The investigators hypothesize that coccygectomy will not improve scores on the Short Form-36 (SF-36), Oswestry Disability Scale (ODI), tolerable sitting time, or Visual Analog Pain Scale (VAS). Also, the investigators hypothesize that there are no independent variables associated with improved outcomes.

Outcome Measures
Primary Outcomes (11)
Pain Change From Baseline at 2 Years
Patients will complete the100mm Visual Analog Scale (VAS) at Baseline and 2 years after procedure. Patient will be instructed to indicate pain intensity by marking a 100mm line where one end, 0 indicates no pain and 100 indicates extreme pain on the other end.
Baseline,1 year and 2 years
Patient Health Status- SF-36v2:Physical Functioning
The SF-36 is on a 0-100 scale, with higher scores indicating a more favorable/better health state.
Baseline,1 year and 2 years
Patient Health Status- SF-36v2: Role Functioning-Physical
The SF-36 is on a 0-100 scale, with higher scores indicating a more favorable/better health state.
Baseline,1 year and 2 years
Patient Health Status-SF-36v2: Role Functioning- Emotional
The SF-36 is on a 0-100 scale, with higher scores indicating a more favorable/better health state.

Lower Back Disability
Oswestry Disability Index used to measure a patient's permanent functional disability. Scores range from 0 to 100. scores between 0 and 20 described as "minimal disability", scores between 21and 40 described as "moderate disability",scores between 41and 60 described as "severe disability",scores between 61 and 80 described as "crippled" and scores between 81 and 100 described as " bed bounded"
