Gamma probe guided surgery for osteoid osteoma: is there any additive value of quantitative bone scintigraphy?

چکیده
OBJECTIVE The aim of this study is to evaluate the efficiency of gamma probe guided osteoid osteoma surgery and the applicability of quantitative analyses obtained from preoperative bone scan images. MATERIAL AND METHODS This study involved 12 osteoid osteoma patients who were treated with gamma probe guided surgery after preoperative bone scan. The calculated contrast ratios between nidus and adjacent healthy bone from preoperative bone scan and the calculated percentages of count reduction after resection of nidus during intraoperative gamma probe application were compared. Patients were followed up for any recurrence or complications. RESULTS The mean contrast ratio between nidus and adjacent healthy bone calculated from preoperative bone scan was 43.6% (range 33-53%). Following the nidus excision, an average of 55.8% (range 28-73%) count reduction was estimated with gamma probe in the tumor area. There was no correlation between preoperative scintigraphic contrast ratio and intraoperative gamma probe count reduction ratio (r = 0.46, p = 0.13). Complete cure was achieved in 11 (92%) patients with single operation, during the postoperative follow up period. None of the patients had any major or minor complications during or after the surgery. CONCLUSIONS Due to high clinical success and low complication rate in osteoid osteoma surgery, gamma probe application is an effective and safe method that should be used more extensively in daily practice.

Two cases of osteoid osteoma tumor (OO) are presented and our early experience with intraoperative gamma probing to localize OO during surgery is reported. The concept of radioguided surgery was developed 60 years ago and the gamma detection probe technology for radioguided biopsy and/or resection of bone lesions has been applied since the early 1980s. Bone scintigraphy is very important for in...

Osteoid osteoma is a benign bone tumor that rarely involves joints. Although there are several reports of arthroscopic osteoid osteoma excisions, to our knowledge, there are no reports of this type of treatment for osteoid osteoma in carpal bones. We report two cases of arthroscopic (a person who had a pain in the left wrist and the other one with carpal tunnel syndrome) with excision of oste...

Osteoid osteoma is a benign bone tumor that when located on the base of the coracoids process of the scapula is very rare and diagnosis and treatment is often delayed because of its rarity. Almost any bone can be involved, but half of cases involve the femur or tibia. The radiologic features of osteoid osteoma are well known, but these tumors may present with unusual features and be easily misd...
