[Comparison of clinical effects of two anterior cervical decompression with fusion on treating two segment cervical spondylotic myelopathy].

Objective: To explore the clinical effects of anterior cervical discectomy with fusion (ACDF) and anterior cervical corpectomy with fusion (ACCF) in treating adjacent two-segment cervical spondylotic myelopathy (CSM).

Methods: The clinical data of 37 patients with adjacent two segment CSM treated from January 2016 to December 2017 were retrospectively analyzed, including 15 males and 22 females, aged from 43 to 69 years old with an average of 54.6 years.

[Effect observation of percutaneous pedicle screw fixation combined with percutaneous vertebroplasty for the treatment of osteoporotic thoracolumbar fractures].

Objective: To evaluate the clinical effects of percutaneous pedicle screw fixation(PPSF) combined with percutaneous vertebroplasty(PVP) for the treatment of osteoporotic thoracolumbar fractures.

Methods: The clinical data of 94 patients with osteoporotic thoracolumbar fractures treated from January 2014 to December 2015 were retrospectively analyzed. There were 31 males and 63 females, aged from 65 to 70 years old with an average of 67.

[Case-control study on minimally invasive percutaneous plate osteosynthesis for the treatment of distal tibial comminuted fractures at different operation times].

Objective: To compare clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) in treating distal tibial comminuted fractures at early and delayed stage.

Methods: From January 2006 to January 2012,66 patients with distal tibial comminuted fractures were treated by MIPPO. All patients were divided into primary group and delayed group according to operation time.
