A retrospective review of surgically treated lower-extremity long-bone fractures in wheelchair-bound patients was conducted. Between October 2000 and July 2009, eleven lower-extremity fractures in 9 wheelchair-bound patients underwent surgical fixation. The Short Musculoskeletal Function Assessment, Short Form, and Spinal Cord Injury Quality of Life questionnaires were used to assess functional...

INTRODUCTION The Segond injury corresponds to a marginal avulsion fracture of lateral tibial plateau, resultant from flexion traumas, stress in varus and internal rotation. The structure responsible for avulsion is the lateral collateral ligament, and anterior cruciate ligament and lateral meniscal injuries are also frequently present(1-4). Hall and Hochman(5) provided the first report of an in...

BACKGROUND The rat fracture fixation models have been widely adopted, but current implant designs suffer from operational difficulty, massive soft-tissue dissection, and radiological intervention. The authors developed a new tibia fracture-healing model using minor invasive intramedullary fixations with polyetheretherketone (PEEK) threaded rods, which have excellent x-ray translucency and no ma...

The diaphyseal tibia fracture is best treated with intramedullary nail but in some cases where the nail is not applicable, plate fixation will be the next option of fixation. The extensile anterior approach is normally used for conventional compression plate fixation in tibia shaft fractures. The extensive surgical dissection may devitalizes the bony fragments and interfere with the fracture un...

The combination of plate and intramedullary nailing has been established as the treatment proximal tibial fractures. Nevertheless, at distal end tibia, application plate-assisted is rarely applied a therapeutic technique. authors provide technical note on use reduction plating technique for nail insertion management tibia fractures.

OBJECTIVE To compare the fixation stability of intramedullary nails to that of locked plates for the treatment of distal metaphyseal tibia and fibula fractures. METHODS A simulated, distal metaphyseal tibia fracture was created in 8 pairs of cadaveric tibia-fibula specimens. One of each pair was treated using an intramedullary nail (Trigen IM Nail System; SN Richards, Memphis, TN) and the oth...

INTRODUCTION Aging decreases chondrogenesis, bone formation, callus vascularization and remodeling during facture healing in mice, which is associated with reduced cyclooxygenase-2 (COX-2) expression, and is restored by administration of an EP4 agonist. Activation of the EP4 receptor stimulates cAMP and activation of the protein kinase A (PKA) signaling pathway. These findings suggest that enha...

INTRODUCTION Monocondylar tibia plateau fractures with non-comminuted fragments can be treated using percutaneous screws. Currently indirect methods of reduction are used and thus the technique is limited to fragments with less than 5 mm depression. The first author has designed a device for direct elevation and reduction of the fragments thus potentially expanding the indications of percutaneo...

This case report illustratesa theory of a mechanism of injury for anterior cruciate ligament (ACL) tears. Studies show ACL injuries can occur with maximal quadriceps muscle contraction. When the timing of the foot plant is miscalculated and is a split second later than planned, the exaggerated muscle contractions cause the tibia to shift more anterior than what would have occurred had the foot ...
