Haptic Robot-assisted Surgery Improves Accuracy of Wide Resection of Bone Tumors: A Pilot Study

Fazel Khan MD, Andrew Pearle MD, Christopher Lightcap PhD, Patrick J. Boland MD, John H. Healey MD

Accurate reproduction of the preoperative plan at the time of surgery is critical for wide resection of primary bone tumors. Robotic technology can potentially help the surgeon reproduce a given preoperative plan, but yielding control of cutting instruments to a robot introduces potentially serious complications. We developed a novel passive (“haptics”) robot-assisted resection technique for primary bone sarcomas that takes advantage of robotic accuracy while still leaving control of the cutting instrument in the hands of the surgeon.

Staples Equal Sutures for Skin Closure After Soft Tissue Tumor Resection

David C. Moore BA, Meredith H. Sellers BA, Kristin R. Archer PhD, DPT, Herbert S. Schwartz MD, Ginger E. Holt MD

Wound closure accounts for a relatively constant portion of the time required to complete a surgical case. Both longer closure times and wound infections contribute to higher medical costs and patient morbidity.

Compressive Osseointegration Into a Custom Acetabular Implant Masquerading as Tumor Recurrence: A Case Report

Adam J. Schwartz MD, Christopher P. Beauchamp MD

Compressive osseointegration is a durable method of method of achieving fixation in long-bone reconstruction, and radiographic findings are well described. The radiographic appearance of integration into the pelvis is poorly defined in the available literature.

Which Treatment is the Best for Giant Cell Tumors of the Distal Radius? A Meta-analysis

Yu-peng Liu MD, PhD, Kang-hua Li MD, Bu-hua Sun MD, PhD

Intralesional excision and en bloc resection are used to treat giant cell tumors (GCTs) of the distal radius. However, it is unclear whether one provides lower rates of recurrences and fewer complications, and whether the use of polymethylmethacrylate (PMMA) after curettage reduces the risk of recurrence.

Surgical Technique: Unicondylar Osteoallograft Prosthesis Composite in Tumor Limb Salvage Surgery

Hongbin Fan MD, Zheng Guo MD, Zhen Wang MD, Jing Li MD, Xiangdong Li MD

After resecting tumors confined to one femoral condyle, a unicondylar osteoarticular allograft can be used for reconstruction without sacrificing the uninvolved condyle. However, unicondylar osteoarticular allografts have been associated with a high rate of joint degeneration. We describe a unicondylar osteoallograft prosthesis composite reconstruction replacing only one side of the joint to reduce compartment degeneration and avoid contamination of the tibia, but the survival, function, and complications of a unicondylar osteoallograft prosthesis composite are unclear.

Osteoporosis in Children and Young Adults: A Late Effect After Chemotherapy for Bone Sarcoma

Ulrike Michaela Pirker-Frühauf MD, Jörg Friesenbichler MD, Ernst-Christian Urban MD, Barbara Obermayer-Pietsch MD, Andreas Leithner MD

Premature bone loss after childhood chemotherapy may be underestimated in patients with bone sarcoma. Methotrexate (MTX), a standard agent in osteosarcoma protocols, reportedly reduces bone mineral density (BMD). The literature, however, has reported cases of BMD reduction in patients with Ewing's sarcoma treated without MTX. Thus, it is unclear whether osteoporosis after chemotherapy relates to MTX or to other factors.

2011 Mid-America Orthopaedic Association Dallas B. Phemister Physician in Training Award: Can Musculoskeletal Tumors be Diagnosed with Ultrasound Fusion-Guided Biopsy?

Jad G. Khalil MD, Michael P. Mott MD, Theodore W. Parsons MD, Trevor R. Banka MD, Marnix Holsbeeck MD

Percutaneous biopsy for musculoskeletal tumors commonly relies on imaging adjuncts including ultrasound (US), CT, or MRI. These modalities however have disadvantages (US) or are cumbersome, not universally available, and costly (CT and MRI). US fusion is a novel technique that fuses previously obtained CT or MRI data with real-time US, which allows biopsies to be performed in an US suite. It has proven useful in various body systems but musculoskeletal applications remain scarce. Our goal is to evaluate the fusion technology and determine its ability to diagnose musculoskeletal tumors.

Prereferral MRI Use in Patients with Musculoskeletal Tumors Is Not Excessive

Christopher T. Martin MD, Jose Morcuende MD, PhD, Joseph A. Buckwalter MS, MD, Benjamin J. Miller MD

Inappropriate MRI use has been targeted as a particular area of concern in orthopaedics, but it is unclear whether and to what extent its use is inappropriate in musculoskeletal oncology.
