There are several options for proximal humerus reconstruction in young children after resection of a malignant tumor and no one technique has been definitively shown to be superior to others, leaving the decision to surgeon and patient choice. Claviculo pro humeri (CPH) is a biologic reconstruction of the proximal humerus using the patient’s ipsilateral clavicle as a rotational osseous flap. CPH represents a potential option for this complicated clinical problem in very young children, but little is known about it because the indications for its use are so uncommon.
To decrease the recurrence rate after intralesional curettage for aneurysmal bone cysts, different adjuvant treatments have been recommended. Liquid nitrogen spray and argon beam coagulation have provided the lowest recurrence rates, but unlike the high-speed burr, these adjuvants are not always available in operating rooms.
What Sports Activity Levels Are Achieved in Patients With Modular Tumor Endoprostheses of Osteosarcoma About the Knee?
Advances in multimodal treatment have improved survival of patients with nonmetastatic osteosarcoma. At the same time, implant design has improved the outcomes of limb salvage with modular endoprostheses. However, little is known about sports activity in long-term survivors with osteosarcoma.
Do Long Term Survivors of Ewing Family of Tumors Experience Low Bone Mineral Density and Increased Fracture Risk?
Multimodal treatment regimens for Ewing’s sarcoma have led to survival rates approaching 70% of patients with no metastases at diagnosis. However, these treatments have long-term side effects. Low bone mineral density (BMD) and risk of fractures can occur owing in part to chemotherapy and limited mobility from local control of the primary tumor.
What Are the Results Using the Modified Trapdoor Procedure to Treat Chondroblastoma of the Femoral Head?
Treatment of chondroblastoma in the femoral head is challenging owing to the particular location and its aggressive nature. There is little published information to guide the surgeon regarding the appropriate approach to treating a chondroblastoma in this location. We developed a modified trapdoor procedure to address this issue. The primary modification is that the window surface of the femoral head is covered by the ligamentum teres rather than cartilage as in the traditional procedure.
Bone metastasis is a poor prognostic indicator in melanoma. Some authors have advocated only palliative treatment for patients with osseous disease.
Despite improvements in treatment of primary osteosarcoma, treatment of patients who have local recurrence is not well defined.
Prosthetic replacement is the most commonly used option for reconstruction of osteoarticular bone loss resulting from bone neoplasm resection or prosthetic failure. Starting in late 2001, we began exclusively using a single system for large-segment osteoarticular reconstruction after tumor resection; to our knowledge, there are no published series from one center evaluating the use of this implant.
Embolization of Hypervascular Bone Metastases Reduces Intraoperative Blood Loss: A Case-control Study
Small case series suggest that preoperative transcatheter arterial embolization minimizes bleeding and facilitates surgery for hypervascular metastatic bone tumors. However, control groups would make our confidence in clinical recommendations stronger, but small patient numbers make prospective trials difficult to conduct on this topic.
What Are the 5-year Survivorship Outcomes of Compressive Endoprosthetic Osseointegration Fixation of the Femur?
Aseptic complications such as stress shielding leading to bone loss are major problems associated with revision of cemented and uncemented long-stem tumor endoprostheses. Endoprosthetic reconstruction using compressive osseointegration fixation is a relatively new limb salvage technology designed to enhance osseointegration, prevent stress shielding, and provide fixation for short end-segments.
