BACKGROUND Locking plates transmit load through fixed-angle locking screws instead of relying on plate-to-bone compression. Therefore, locking screws may induce higher stress at the screw-bone interface than that seen with conventional nonlocked plating. This study investigated whether locked plating in osteoporotic diaphyseal bone causes a greater periprosthetic fracture risk than conventional...

The advent of internal fixation with bone plates and screws represents a tremendous advancement in the methods of fracture fixation. During this era, the emphasis was on anatomic reconstruction and rigid internal fixation. Although these principles are applicable to a great number of fractures, not all can be treated in this manner. In fact, the disruption of the soft tissue envelope required t...

The principle of the locking compression plate (LCP) is represented by the combination of two completely different anchorage technologies and two opposed principles of osteosynthesis in one implant it combines the principles of conventional plate osteosynthesis for direct anatomical reduction with those of bridging plate osteosynthesis. Since the LCP can be used as a conventional plate using on...

ABSTRACT BACKGROUND Minimally invasive internal fixation is also called "biological internal fixation". This concept is used widely in the treatment of various fractures but to date, there have been no report about such application in the repair of isolated ulnar bone fractures. METHODS Eleven patients with fracture of isolated ulnar bone (four AO type 22A11 and seven AO type 22A12), mean ...

Background: Manubriosternal joint dislocation as a result of trauma is rare with only few case reports published in the literature. Materials that have been used for fixation of displaced manubriosternal joint are steel wires, polydioxanone ropes, and plates with screws. Case: We present a case of manubriosternal dislocation in which fixation was done with locking compression plate. It is a cas...

BACKGROUND The Lapidus bunionectomy is a popular procedure for severe bunion deformity where metatarsus primus varus is equal to or exceeds 15 degrees. We evaluated a new locking compression plate which may improve outcomes with the Lapidus procedure. METHODS Ten matched pairs of cadaver feet were used to compare the standard crossed 4.0-mm compression screw method of fixation to the LPS Lapi...
