BACKGROUND: Benign lesions in the proximal femur can cause pathologic fractures. To avoid fracture, benign tumors and tumor-like lesions in this region often are treated surgically, yet there have been few reports regarding the decision-making processes or protocols for nonsurgical treatment of these lesions. QUESTIONS/PURPOSES: In this study, we asked (1) whether some benign lesions of the proximal femur can be managed safely using a conservative protocol, and (2) if observed according to such a protocol, what are the outcomes of such lesions at this anatomic site? METHODS: Fifty-four consecutive patients who had been followed for at least 12 months were enrolled in this study. The mean age of the patients at first visit was 38 years (range, 13-70 years), and the minimum followup was 12 months (mean, 25 months; range, 12-59 months). After ruling out malignancy, lesions were categorized as aggressive benign tumors or nonaggressive benign lesions using a standardized approach. We used conservative treatment for most patients with nonaggressive, benign lesions. Surgery was performed only for patients with nonaggressive lesions who met our fracture risk criteria: pain on initiating hip movement, progressively worsening pain, cortical thinning, and the absence of a sclerotic margin. RESULTS: Of the 47 patients with a nonaggressive, benign lesion without fracture at presentation, 83% were treated conservatively and only 10% of these patients had progression of the lesion. No new pathologic fractures developed during followup. In 88% of patients who presented with pain that was managed conservatively, pain improved either partially or completely at final followup. CONCLUSIONS: Most nonaggressive, benign lesions in the proximal femur can be treated conservatively, and our protocol appears to be a useful outpatient guideline. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

ABSTRACT: OBJECTIVE: The radiologist plays an important role in the workup and staging of bone tumors. The purpose of this article is to review that role and to discuss recent changes to the primary malignant bone tumor staging system developed by the American Joint Committee on Cancer. CONCLUSION: Knowledge of staging parameters for the diagnosis and management of bone tumors will help the radiologist to generate meaningful reports for the referring physician.American Journal of Roentgenology 05/2006; 186(4):967-76.

ABSTRACT: A weighted scoring system is proposed to quantify the risk of sustaining a pathologic fracture through a metastatic lesion in a long bone. This system objectively analyzes and combines four roentgenographic and clinical risk factors into a single score. Retrospective analysis of metastatic long bone lesions was completed in 78 lesions that had been irradiated without prophylactic surgical fixation. Clinical data and roentgenograms were scored prior to irradiation by independent observers. The outcome identified 51 lesions that did not fracture during the subsequent six months and 27 lesions that fractured within six months. A mean score of 7 was found in the nonfracture group, whereas the fracture group had a mean score of 10. The percentage risk of a lesion sustaining a pathologic fracture could be predicted for any given score. As the score increased above 7, so did the percentage risk of fracture. It is suggested that all metastatic lesions in long bones be evaluated prior to irradiation. Lesions with scores of 7 or lower can be safely irradiated without risk of fracture, while lesions with scores of 8 or higher require prophylactic internal fixation prior to irradiation.Clinical Orthopaedics and Related Research 01/1990; 415(249):256-64.
