Small recent case series using CT-based navigation suggest such approaches may aid in surgical planning and improve accuracy of intended resections, but the accuracy and clinical use have not been confirmed.
Surgical Technique: Tibia Cortical Strut Autograft Interposition Arthrodesis After Distal Radius Resection
Distal radius reconstruction after en bloc tumor resection remains a surgical challenge. Although several surgical techniques, either reconstructing the wrist or achieving a stable arthrodesis, have been described, it is unclear to what degree these restore function.
Approximately one in five patients with giant cell tumor of bone presents with a pathologic fracture. However, recurrence rates after resection or curettage differ substantially in the literature and it is unclear when curettage is reasonable after fracture.
Using the CUSUM Test to Control the Proportion of Inadequate Open Biopsies of Musculoskeletal Tumors
Biopsies of musculoskeletal tumors lead to alterations in treatment in almost 20% of cases. Control charts are useful to ensure that a process is operating at a predetermined level of performance, although their use has not been demonstrated in assessing the adequacy of musculoskeletal biopsies.
Joint-preserving surgery is performed in select patients with bone sarcomas of extremities and allows patients to retain the native joint with better joint function. However, recurrences may relate to achieving adequate margins and there is frequently little room for error in tumors close to the joint surface. Further, the tumor margin on preoperative CT and/or MR images is difficult to transpose to the actual extent of tumor in the bone in the operating room.
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.
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
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.
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.
