Introduction In fracture healing mesenchymal stem cells (MSCs) infiltrate the wound site, proliferate extensively and differentiate along a cartilaginous or an osteogenic lineage in response to local environmental cues. The mechanical environment within a fracture callus may regulate endochondral ossification during fracture healing in one of two ways. Firstly, the biophysical stimuli, such as ...
Arthroscopic reduction and internal fixation (ARIF) is recommended as state-of-the-art treatment for patients with pure compression fracture of the tibial plateau. We describe a new technique for ARIF of pure compression tibial plateau fractures that uses a cannulated, bioabsorbable interference screw. After a guide pin is placed in the center of the compressed fragment and a tamp is used to el...
STUDY DESIGN Retrospective analysis of a prospectively collected patient database. OBJECTIVE To investigate the significance and relevant factors of postural kyphosis reduction during posterior surgical treatment of thoracolumbar burst fracture. SUMMARY OF BACKGROUND DATA Optimal reduction of kyphosis is a goal in the surgical treatment of thoracolumbar burst fracture. Several factors are k...
Vertebroplasty is a procedure in which polymethlymethacrylate (PMMA) is injected into a vertebral body compression fracture. It has been suggested that fractues greater than 65% to 70% of the original vertebral body height are too compressed to be treated successfully with this procedure. We describe six patients with severe compression fractures that were successfully treated with vertebroplas...
The concept of localization during the postpeak of compressive strain softening is presented. To explore localization in compression, a feedback-control method using a linear combination of displacement and force that partially subtracts the elastic response of the specimen to give a stable feedback signal is used. Results are presented from two test series (45 and 90 MPa) that use this method ...
This is an updated review of management of vertebral compression fracture for both benign osteoporotic and malignant causes. Vertebral compression fracture radiologic imaging evaluation is discussed. A literature review is provided of current indications for vertebral augmentation with percutaneous vertebroplasty and kyphoplasty as well as medical management. Limitations and potential benefits ...
