Pelvic osteoplasty in osteolytic metastases: technical approach under fluoroscopic guidance and early clinical results.
OBJECTIVE
To describe a new fluoroscopically guided technique for osteoplasty (or cementoplasty) of the superior and inferior pubic rami and ischial tuberosities and to provide information about the access routes and initial results on pain management after this technique.


METHODS
Twenty-three lytic metastases of the superior and inferior pubic rami and ischial tuberosities were treated in 14 consecutive patients. Percutaneous access of the bones was performed under fluoroscopy. All patients had pain refractory to radiation and narcotic therapy and were unsuitable candidates for surgery according to multidisciplinary consensus.


RESULTS
Technical success was achieved in all cases. Clinically, effective pain relief was obtained in 92% of patients. One intraarticular asymptomatic minor complication and one major complication resulting from leakage near the pudendal nerve were observed. The latter was subsequently treated by radiofrequency ablation.


CONCLUSIONS
Pelvic osteoplasty appears to be a safe and highly effective palliative therapy for painful osteolytic malignant bone metastases.
