Gamma Probe-Guided Surgery in Postoperative Recurrent Osteoid Osteoma of Left Index Finger

Osteoid osteomas are painful benign osteoblastic tumors that usually affect the metaphysis or diaphysis of long bones. Hands are rarely involved. Identification of recurrent lesion by anatomical imaging modalities is a challenge especially in postoperative setting. Diagnosis of osteoid osteoma is based on typical clinical signs, radiographs, bone scintigraphy, thin-slice computed tomography, or magnetic resonance imaging. Atypical locations, multicentricity of nidus, or incomplete excision of the nidus result in a high rate of recurrence. Here we present a case of recurrent osteoid osteoma at an unusual site in left index finger and was operated under gamma probe guidance.
