Curettage and Graft Alleviates Athletic-Limiting Pain in Benign Lytic Bone Lesions

Vincent M. Moretti MD, Rachel L. Slotcavage MD, Eileen A. Crawford MD, Richard D. Lackman MD, Christian M. Ogilvie MD

Solitary bone cysts (SBC), nonossifying fibromas (NOF), and fibrous dysplasia (FD) create benign intramedullary lytic bone lesions. They are typically asymptomatic and treated conservatively. We present a series of lesions that caused performance-limiting pain in young athletes, a symptom phenomenon and possible treatment indication that has been poorly described in the literature.

Multiplanar Osteotomy with Limited Wide Margins: A Tissue Preserving Surgical Technique for High-grade Bone Sarcomas

Raffi S. Avedian MD, Rex C. Haydon MD, PhD, Terrance D. Peabody MD

Limb-salvage surgery has been used during the last several decades to treat patients with high-grade bone sarcomas. In the short- and intermediate-term these surgeries have been associated with relatively good function and low revision rates. However, long-term studies show a high rate of soft tissue, implant, and bone-related complications. Multiplanar osteotomy with limited wide margins uses angled bone cuts to resect bone tumors with the goal of complete tumor removal while sparing host tissue although its impact on local recurrence is not known.

Extraarticular Knee Resection for Sarcomas with Preservation of the Extensor Mechanism: Surgical Technique and Review of Cases

Pawel Zwolak MD, Stefanie P. Kühnel MD, Bruno Fuchs MD, PhD

Sarcomas in or contaminating the knee are rare but extremely challenging to treat. Complete resection of the joint is necessary, and often the entire extensor mechanism is removed as well. Reconstruction of the knee is challenging, and the resulting function may be compromised.

Analysis of Nondiagnostic Results after Image-guided Needle Biopsies of Musculoskeletal Lesions

Justin Yang MD, Frank J. Frassica MD, Laura Fayad MD, Douglas P. Clark MD, Kristy L. Weber MD

Image-guided needle biopsies are commonly used to diagnose musculoskeletal tumors, but nondiagnostic (ND) results can delay diagnosis and treatment. It is important to understand which factors or diagnoses predispose to a ND result so that appropriate patient education or a possible change in the clinical plan can be made. Currently it is unclear which factors or specific lesions are more likely to lead to a ND result after image-guided needle biopsy.

Case Report: Mesenchymal Chondrosarcoma of the Lumbar Spine in a Child

Aristidis H. Zibis MD, PhD, M. Wade Shrader MD, Lee S. Segal MD

Chondrosarcomas of the spine constitute 4% to 10% of all primary spinal bone tumors and approximately 70% of the cases occur during the second or third decade of life. Mesenchymal chondrosarcoma is a rare aggressive variant of chondrosarcoma. The prognosis of mesenchymal chondrosarcoma is usually poor with a tendency for late local recurrence and metastasis.

Radiofrequency Ablation of Osteoid Osteoma in Atypical Locations: A Case Series

Shahram Akhlaghpoor MD, Alireza Aziz Ahari MD, Abbas Arjmand Shabestari MD, Mohammad Reza Alinaghizadeh MSc

Osteoid osteoma has a nidus surrounded by sclerotic bone with a size usually less than 20 mm. Its diagnosis is made on typical presentation of nocturnal pain and imaging findings. Excision of the niduses, which are often small and difficult to precisely identify, sometimes may result in resection of surrounding normal bone. Minimally invasive percutaneous treatments have been used to try to minimize resection of normal bone. Although minimally invasive radiofrequency ablation generally relieves pain, its ability to relieve pain is less well known in locations other than lower extremity long bones.

Intercalary Allograft Reconstructions Using a Compressible Intramedullary Nail: A Preliminary Report

Benjamin J. Miller MD, Walter W. Virkus MD

Although intercalary allograft reconstructions are commonly performed using intramedullary devices, they cannot generate compression across host-allograft junctions. Therefore, they sometimes are associated with gap formation and suboptimal healing conditions.

Case Report: Hemosiderotic Fibrohistiocytic Lipomatous Lesion: A Clinicopathologic Characterization

Vincent M. Moretti MD, John S. J. Brooks MD, Christian M. Ogilvie MD

A hemosiderotic fibrohistiocytic lipomatous lesion, also called hemosiderotic fibrolipomatous tumor, is a rare and recently described fibrolipomatous entity. Initially considered the result of a reactive inflammatory process from trauma or vascular disease, newer evidence suggests it may be neoplastic in origin.
