Abstract:
Few cases in which open reduction and internal fixation was performed for displaced pisiform fractures have been reported. We present a new surgical technique for the treatment of depressed intra-articular pisiform fractures. First, the depressed fragment was reduced by pushing the bone tamp. Then, the fracture void resulting from the reduction of the depressed fragment was filled with a shaped hydroxyapatite block. Finally, the fragments were sutured using braided polyblend polyethylene sutures. The postoperative radiography could achieve a well-reduced articular facet, and this procedure had a good clinical outcome.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
