We evaluated the 2- to 7-year results of a rotating-hinge knee replacement after excision of malignant tumors of the knee joint. There were 25 distal femoral and 7 proximal tibial replacements. The 5-year prosthetic survival for distal femoral replacements was 88%, compared with 58% for proximal tibial replacements. Seven patients underwent prosthetic(More)
PURPOSE Life expectancy is routinely used as part of the decision-making process in deciding the value of surgery for the treatment of bone metastases. We sought to investigate the validity of frequently used indices in the prognostication of survival in patients with metastatic bone disease. METHODS The study prospectively assessed 191 patients who(More)
BACKGROUND Limb salvage following resection of a tumor in the proximal part of the humerus poses many challenges. Reconstructive options are limited because of the loss of periarticular soft-tissue stabilizers of the glenohumeral joint in addition to the loss of bone and articular cartilage. The purpose of this study was to evaluate the functional outcome(More)
OBJECTIVE Low-grade myxofibrosarcoma often relentlessly recurs after surgical resection, with an unusual infiltrative growth pattern and sometimes without a discrete tumor nodule at pathologic examination. This study was undertaken to determine and show patterns of recurrent low-grade myxofibrosarcoma at CT and MRI. CONCLUSION Unlike in most other(More)
UNLABELLED Myxofibrosarcoma (MFS) has a high local failure rate of up to 79%. We conducted a retrospective analysis on all patients with the diagnosis of myxofibrosarcoma seen between 1990 and 2004 to assess whether improved imaging with MRI reduced local recurrence, increased survival, and whether radiotherapy following resection influenced outcome.(More)
BACKGROUND Pathologic proximal femur fractures result in substantial morbidity for patients with skeletal metastases. Surgical treatment is widely regarded as effective; however, failure rates associated with the most commonly used operative treatments are not well defined. QUESTIONS/PURPOSES We therefore compared surgical treatment failure rates among(More)
PURPOSE Unstable, dorsal, intra-articular, fracture-dislocations of the proximal interphalangeal (PIP) joint can be difficult to treat and often lead to long-term pain, stiffness, and functional deficit. We present the outcomes of patients sustaining such injuries that were treated by a novel dynamic external fixator. This fixator uses a system of K-wires(More)
We report a rare malignant endovascular papillary angioendothelioma (Dabska tumor) arising within the deep periosteal soft tissue of the ulna of an 8-year-old girl. To our knowledge, this is the first report of a Dabska tumor of deep soft tissue that did not extend down from the dermis. This Dabska tumor appears to be a focal change within a larger,(More)
Aneurysmal bone cyst and giant cell tumor of bone have historically been considered benign lesions that can behave in locally aggressive fashion. The clinical and pathologic findings share some common characteristics. When considering a radiographic differential diagnosis, these entities are usually considered together. There are some very distinct(More)
BACKGROUND AND OBJECTIVES Limb-sparing surgery has become the preferred surgical treatment of malignant bone tumors. The objective of this study was to evaluate factors that influence the morbidity and outcome of prosthetic knee replacement after resection of malignant tumors of the distal femur. METHODS Eighty-two patients who had a resection of(More)
