Intraoperative localization of an osteoid-osteoma using a gamma probe.

Department of Orthopedics and Traumatology, School of Medical Sciences, Campinas State University (UNICAMP), Av. Vital Brasil, 251-Cidade Universitaria Zeferino Vaz, Campinas, CEP 13083-970, SP, Brazil.

The purpose of this study was to evaluate whether intraoperative nidus detection with a hand-held gamma probe was efficient enough for use as a routine procedure. Thirty-seven patients with osteoid-osteomas were submitted to surgical treatment. The first group consisted of 19 patients submitted to open nidus resection using a hand-held gamma probe as guide. The control group consisted of 18 patients operated on by conventional technique. The procedures were classified as successful if nidus resection could be confirmed by histology or postoperative imaging studies. Patients in the gamma group were followed for a mean of 13 months; patients in the control group for a mean of 39 months. In the gamma group, 17/19 procedures were successful; in the control group, only 12/18 procedures were successful. The gamma probe helped to locate the osteoid-osteoma nidus, and the same probe could be used in various hospitals.
