Compare the results of internal fixation of shaft of humerus fractures using dynamic compression plating (DCP) or antegrade interlocking intramedullary nail (IMN). Fifty patients with diaphyseal fracture of the shaft of the humerus and fulfilling the inclusion criterion were randomly assigned to one of the two groups. Twenty-five patients were managed with closed antegrade interlocking intramed...

PURPOSE Lens fiber cell membranes contain aquaporin-0 (AQP0), which constitutes approximately 50% of the total fiber cell membrane proteins and has a dual function as a water channel protein and an adhesion molecule. Fiber cell membranes also develop an elaborate interlocking system that is required for maintaining structural order, stability, and lens transparency. Herein, we used an AQP0-defi...

BACKGROUND When an implant is inserted in the bone the healing process starts to osseointegrate the implant by creating new bone that interlocks with the implant. Biomechanical interlocking capacity is commonly evaluated in in vivo experiments. It would be beneficial to find a numerical method to evaluate the interlocking capacity of different surface structures with bone. In the present study,...

Recent advances in 3D printing technologies bring wide range of applications from fast prototyping to product manufacturing. However, one intrinsic limitation of 3D printing is that we cannot fabricate a single object that is larger than the working volume of a 3D printer. To address this issue, we may partition the given object into 3D parts of manageable sizes for printing, and then assemble ...

OBJECTIVE To compare ender nails and unreamed interlocking nails in a randomized clinical trial study. METHODS From March 2001 to March 2003, 131 patients with tibial fractures of the central two thirds of the tibia were admitted to the emergency ward of Shohada Hospital, Tabriz, Iran and were randomized to either an ender tibial nail or an undreamed interlocking tibial nail as their primary ...

The ability of an interlocking screw fixation technique to minimize bone loss related to stress shielding in the tibia was investigated and compared to the abilities of cement and press-fit fixation. Full bony ingrowth has been associated with greater stress shielding than partial ingrowth; therefore, the effect of intimate bonding of the stem to bone on subsequent bone loss was also studied. A...
