STUDY DESIGN A single surgeon case series and meta-analysis of literature. OBJECTIVE To evaluate the clinical outcome and patient satisfaction following coccygectomy for coccygodynia in adults and children using a curvilinear paramedian skin incision and to conduct a meta-analysis of the literature to determine the associated infection rate with different surgical factors. METHODS 45 consecutive patients (40 adults and 5 children) underwent surgical coccygectomy for persistent coccygodynia symptoms using a paramedian curvilinear incision. Postoperative clinical outcome scores, patients' satisfaction and wound complications were assessed. A systematic literature search using specific MesH terms was then conducted covering the period from 1980 to 2020. Only those studies reporting infection rates post coccygectomy were included in a meta-analysis. RESULTS The average age of patients was 39 years with a mean duration of symptoms prior to surgery of 7.4 years. The mean Oswestry Disability Index improved from 29 to 7.7 (P < .001). The mean pain Visual analogue scale improved from 8 to 2 (P < .001) and the median patient satisfaction score was 8 (out of 10) suggesting good to excellent outcome. The clinical improvement was the same in children and adults. There was a total of 5 (11%) wound infections, 2 of which needed surgical debridement. Meta-analysis of the included studies showed that the use of prophylactic antibiotics for 24 hours, nonabsorbable skin sutures and glue were associated with low infection rate. CONCLUSIONS Coccygectomy using curvilinear paramedian skin incision for chronic coccygodynia is an effective procedure with similar or lower complication rates as reported in the literature.
