To compare therapeutic effects of three fixation methods with three Kirschner wires,and to find the best fixation method. ⋯ There are different effects among three kinds of operative approaches for the humerus supracondylar fractures. The fixation method with one Kirschner wire through middle part of coronoid fossa is better than the other two fixation methods.
-
To investigate the clinical results of the proximal femoral nail antirotation (PFNA) system in the treatment of unstable intertrochanteric femoral fractures. ⋯ Due to advantages of high union rate, short operation time, and early postoperative mobilization, PFNA osteosynthesis is an idea method for surgical treatment of unstable intertrochanteric femoral fractures.

Comparative Study
[Anatomic comparison between spinous process screws and pedicle screws techniques of the second cervical vertebar].
To compare anatomic difference between spinous process screws and pedicle screws techniques of the second cervical vertebra. ⋯ The C2 spinous process screw fixation has the anatomic feasibility and is easier to perform than pedicle screw fixation.
-
To investigate the clinical results of pedicle-screw placement and reduction on the level of injured vertebrae in treating thoracolumbar fractures. ⋯ Posterior short-segment fixation system and pedicle-screw placement on level of injured vertebrae is one kind of effective method in treating thoracolumbar fracture, which can maintain corrective effect and obtain better clinical outcomes.

Spinal cord injury is a difficult medical problem and current therapeutic methods could not obtain satisfactory results. Recent 20 years, stem cell technology developed rapidly, embryonic stem cells and adult stem cells were used for treating neurological disease and nerve injury of animal models and the clinical results were confirmed. ⋯ Recently, induced pluripotent stem cells were developed as a new method for the treatment of spinal cord injuries by the autologous transplantation. Starting from this work, the purpose of this review is to assess the differentiate ability of induced pluripotent stem cells into neurocyte and review the latest developments in this area.
