To investigate the hidden blood loss and related risk factors of osteoporotic vertebral compression fractures after percutaneous kyphoplasty. ⋯ There is a certain degree of occult hemorrhage in kyphoplasty for osteoporotic vertebral compression fractures. The risk factors of hidden hemorrhage are diabetes history, operation method, operation time, operative segment and number, loss of vertebral height and recovery ratio.

Randomized Controlled Trial
[Case control study on ultrasound guided microtraumatic treatment of acute subacromial bursitis].
To evaluate the efficacy of ultrasound guided microtraumatic treatment of acute subacromial bursitis. ⋯ The ultrasound guided microtraumatic treatment of acute subacromial bursitis worked faster than traditional closed therapy. The short term curative effect and the comprehensive curative effect is better than the traditional closed treatment. The US guided subacromial injection technique is effective in guiding the needle into the subacromial bursa in patients with acute subacromial bursitis.

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 compare of clinical effects of different surgical methods in the treatment of elderly femoral neck fractures. ⋯ For elderly femoral neck patients, if there is a significant shift in the fracture (Garden III, IV), the preferred treatment is hip replacement. Postoperative complications are relatively small, satisfactory joint function recovery. If the fracture displacement is not obvious (Garden type I, II) or patients with more medical diseases, poor physical condition, poor surgical tolerance, postoperative life expectancy is not high, the first choice is closed reduction and cannulated screw fixation.

To investigate the advantages of minimally invasive surgery-transforaminal lumbar interbody fusion(MIS-TLIF) under Quadrant channel in the treatment of grade I and II degree degenerative lumbar spondylolisthesis. ⋯ The MIS-TLIF under Quadrant channel has advantage of minimally invasive trauma, less bleeding, faster function recovery and better effect in surgical treatment of grade I and II degree degenerative lumbar spondylolisthesis.
