Abstract Aim Establishing an early and accurate diagnosis in cases of suspected pathological fractures is crucial to initiate optimal treatment without delay. The use of percutaneous biopsy has become popular over the past few years. However, there is a paucity of information regarding the efficacy and safety of percutaneous biopsy procedures guided by fluoroscopy. Methods A total of 137 percutaneous C‐arm fluoroscopy‐guided core needle biopsy (CNB) procedures were performed in 135 patients with suspected pathological fractures. The sensitivity, specificity, accuracy, and overall prognostic value of these procedures were evaluated. Complications, if any, were documented for all cases. Results The overall sensitivity, specificity, and accuracy were 82.0%, 100%, and 83.2%, respectively. The positive and negative predictive value was 100% and 28.1%, respectively. There were 23 “false negative” cases in our study, of which 15 were benign lesions and eight were malignant tumors. No “false‐positives” were found. Major procedure‐related complications occurred in three patients (2.2%). These complications, however, did not alter the prognosis of these patients. Conclusion Percutaneous C‐arm fluoroscopy‐guided biopsy procedures are both effective and safe for diagnosis of suspected pathological fractures in the appendicular skeleton.
