Comparative Study
[Comparison of PFNA and InterTAN intramedullary nail in treating unstable femoral intertrochanteric fractures].
To compare the clinical effects of PFNA and InterTAN for the treatment of unstable intertrochanteric fractures in the elderly patients. ⋯ InterTAN with stronger anti-rotation function is more suitable for patients with early weight-bearing and it reduces the incidence rates of hip varus, femoral head screw cut-out and femoral neck shortening. However, for those patients with osteoporosis or unfit for surgery, PFNA is a good option. As the limited follow-up duration, long-term effects of the two surgical methods needs to be further observed and studied.

To evaluate the feasibility of minimally invasive internal fixation of pelvic anterior and posterior ring for the treatment of type C pelvic fracture, and to explore its operative techniques and therapeutic efficacy. ⋯ Internal fixation with reconstructive plates through the ilioinguinal approach and with percutaneous iliosacral screw for type C pelvic facture on pelvic anterior ring and pelvic posterior ring respectively have advantages of shorter operation time, smaller invasive trauma, less blood loss and etc. Thus, this technique is safe and practicable, yielding satisfying results.
-
To investigate the computer-assisted virtual reduction combined with 3D printing technique as preoperative planning and assess their therapeutic effects. ⋯ The computer-assisted virtual reduction combined with 3D printing technique can reduce the operative time, volume of intraoperative blood loss and blood transfusion in acetabular surgeries for patients with acetabular fractures. The technique is an effective method for preoperative planning, which worth promoting.

To retrospective analysis the mid-term follow-up effect of hip joint replacement in elderly patients with failure of intertrochanteric fractures of the hip joint internal fixation. ⋯ Salvage THA surgery could improve the hip function and the quality of life for old patients with intertrochanteric fracture fixation failure, and the middle-term follow-up results support that.

To investigate surgical skills and clinical effects of manipulative reduction and percutaneous Kirschner wire internal fixation in treating grade IV supination-external rotation ankle fractures. ⋯ Manipulative reduction and percutaneous Kirschner wire internal fixation in treating grade IV supination-external rotation ankle fractures has advantages of reliable efficacy, less complications. But higher require techniques were required for closed reduction. It is not suitable for severe crushed fracture and compressive articular surface fracture.
