Background: osteoblastoma is a bone-forming tumor accounting for about 1% of all primary bone tumors and 3% of benign bone tumors. The gold-standard treatment is surgical excision; nevertheless, minimally invasive radiological techniques such as thermoablation and, more recently, high intensity focused ultrasound are gaining more importance. The aim of the present paper is to analyze surgical indications based on our experience and on the evidences in the literature. Methods: all patients affected by osteoblastoma who underwent surgical excision in January 2009 and December 2018 were reviewed; eleven patients were enrolled in the study. The epidemiological aspects, size of the disease and site of onset, symptoms, surgery type, indications, and results are reported for every case. Results: all treatments were based on a preoperative diagnosis; pain was constant in all cases. Intralesional surgeries were performed in 9 out of 11 cases; the remaining 2 cases underwent wide resection. No early or late complications occurred after the surgical procedure. The indications for surgery were lesions very close to nerves or joints, unclear diagnosis, risk of fracture, lesion too large for radiofrequency thermoablation, or failure of minimally invasive treatments. At a medium follow-up of 88 months, no local recurrences were verified. Conclusions: osteoblastoma is a rare tumor with difficult diagnosis. Identification is based on symptoms, imaging, and histology. When possible, minimally invasive techniques is preferred for treatment but surgery is still considered the gold standard.

Abstract
Background: osteoblastoma is a bone-forming tumor accounting for about 1% of all primary bone tumors and 3% of benign bone tumors. The gold-standard treatment is surgical excision; nevertheless, minimally invasive radiological techniques such as thermoablation and, more recently, high intensity focused ultrasound are gaining more importance. The aim of the present paper is to analyze surgical indications based on our experience and on the evidences in the literature. Methods: all patients affected by osteoblastoma who underwent surgical excision in January 2009 and December 2018 were reviewed; eleven patients were enrolled in the study. The epidemiological aspects, size of the disease and site of onset, symptoms, surgery type, indications, and results are reported for every case. Results: all treatments were based on a preoperative diagnosis; pain was constant in all cases. Intralesional surgeries were performed in 9 out of 11 cases; the remaining 2 cases underwent wide resection. No early or late complications occurred after the surgical procedure. The indications for surgery were lesions very close to nerves or joints, unclear diagnosis, risk of fracture, lesion too large for radiofrequency thermoablation, or failure of minimally invasive treatments. At a medium follow-up of 88 months, no local recurrences were verified. Conclusions: osteoblastoma is a rare tumor with difficult diagnosis. Identification is based on symptoms, imaging, and histology. When possible, minimally invasive techniques is preferred for treatment but surgery is still considered the gold standard.File | Dimensione | Formato | |
