To evaluate the middle-long-term clinical effects of unilateral and bilateral percutaneous kyphoplasty(PKP) for vertebral fragility fracture in the elderly. ⋯ Middle-long-term clinical effects of unilateral and bilateral percutaneous kyphoplasty for vertebral fragility fracture are safe and satisfactory, and may be extended as a minimally invasive method. Unilateral approach for PKP has advantages of short operation time, relative less trauma, thus is a more ideal method.
-
To observe different bone cement dispersion types of PVP, PKP and manipulative reduction PVP and their effects in the treatment of senile osteoporotic vertebral compression fractures and the bone cement leakage rate. ⋯ Bone cement dispersion type is different in PVP, PKP and manipulative reduction PVP operation. The bone cement dispersion of mass type and mixed type to recovery of compressed vertebral body is better than diffusion type, and there is no obvious difference in clinical effect in different bone cement dispersion type early and middle term.
-
To investigate and the clinical effect of S-ROM modular stem in femur reconstruction in hip revision arthroplasty. ⋯ S-ROM prosthesis has satisfactory results in hip revision arthroplasty with Paprosky II and III femoral defects. Especially for patients with Crowe IV DDH and other proximal femoral deformities, it is possible to adapt to the medullary cavity morphology. Excellent initial stability, less complications and long-term biological fixation can be achieved with S-ROM in femur revision.
-
To investigate the feasibility and accuracy of a new navigation template for osteotomy in cubitus varus based on computer assistant design and 3D printing technology. ⋯ With the help of 3D printing technology, the accurate osteotomy in cubitus varus assisted by individualized navigate template can be realized. This technology can restore normal anatomical structure of the elbow joint to the greatest extent. It is worthy of popularization and application.
-
To evaluate the efficacy of capsular-enhanced repair with suture anchors in bipolar hemiarthroplasty for the treatment of femoral neck fractures in elderly patients. ⋯ The bipolar hemiarthroplasty with capsular-enhanced repair with suture anchors is effective in reducing postoperative complications of prosthesis dislocation.
