OBJECTIVE The purpose of this study was to analyze the relationship between fracture pattern and the development of acute radiculopathy after osteoporotic lumbar compression fracture. METHODS This study included 59 patients who underwent bone cement augmentation for osteoporotic compression fracture below the L2 level, which can lead to radiculopathic radiating pain. The patients were divided...

In the United States, there are 1.5 million fractures attributed to osteoporosis every year. Among them are 700,000 vertebral fractures.1 Vertebral compression fractures have a greater than 15% reduction in vertebral body height and are most often observed in the thoracolumbar transition zone.2 Patients typically present with back pain and get diagnosed with a vertebral fracture following X-ray...

BACKGROUND Primary immunoglobulin light chain amyloidosis (AL amyloidosis) is a plasma cell disorder which mainly affects heart, kidneys, liver, and peripheral nervous system. Cases of atypical AL amyloidosis presented as spontaneous vertebral compression fractures have been rarely reported, and data about the management and clinical outcomes of the patients are scarce. METHODS Herein, we pre...

BACKGROUND Interlocking nailing, which has become the method of choice for treating fractures of the femoral and tibial shafts, still lacks ability to provide the important contact-compression at the fracture. An intramedullary compression nail is described, which provides axial compression at the fracture site with tightening of the specially designed distal interlocking screw. This uses the s...

Mechanisms of femoral fracture of the condyles and shaft were experimentally investigated through controlled knee impact ofdenuded femurs in six human cadavers. High-speed movies recorded knee joint compression, femoral displacements and deformation, and fracture initiation. Fracture initiated at 10.6 + 2.7 kN knee load after 1.3 + 0.1 cm ofknec joint compression for a 10.1 kg rigid impact at 1...

INTRODUCTION Current methods of fracture care use various adjuncts to try and decrease time to fracture union, improve fracture union rates and enhance functional recovery. Intermittent pneumatic compression (IPC), one such modality, is used in the management of both fractures and soft-tissue injuries. METHODS AND RESULTS A search of PubMed, Medline, CINAHL, DH data and Embase databases was p...

Lesser Model glassy polymers, polymethyl methacrylate (PMMA) and polycarbonate (PC) are used to experimentally probe several aspects of polymer f...

STUDY DESIGN A unique case report. OBJECTIVE To report a case of severe thoracolumbar kyphosis with abdominal compression causing gastric disturbance after treatment of an osteoporotic vertebral compression fracture and its ultimate management by vertebral column resection (VCR). We propose a new terminology "sternum-into-abdomen deformity" to describe this condition. SUMMARY OF BACKGROUND ...
