Objective: To observe and evaluate the clinical effect of cement reinforced pedicle screw fixation in the treatment of osteoporotic thoracolumbar fractures and its effect on the quality of life. Methods: From April 2015 to June 2017, 60 patients with osteoporotic thoracolumbar fractures were selected from Shanxi Coal Center Hospital.The patients were divided into two groups according to different treatment method, with 30 cases in each group.Routine percutaneous vertebroplasty was performed in the control group, and bone cement reinforced pedicle screw fixation was performed in the observation group.The scores of health and function, life satisfaction score, the scores of social and economic factors, self-concept score, visual analogue scale (VAS) and Cobb's angle were calculated and evaluated before operation and 6 months after operation in the two groups. Results: The scores of health and function, life satisfaction, social and economic factors, self-concept in the observation group at 6 months after operation were (60.2±6.0)points, (39.8±4.0)points, (32.0±3.5)points, (47.7±4.0)points, respectively, which were significantly higher than those in the control group[(48.0±5.5)points, (32.4±3.0)points, (29.3±2.0)points, (44.0±3.3)points], the differences were statistically significant (t=8.988.106, 3.668, 3.908, all P<0.05). The VAS score in the observation group was significantly lower than that in the control group at 6 months after operation[(1.5±0.4)points vs.(2.3±0.8)points](t=4.898, P<0.05). The Cobb angle of the observation group[(5.3±1.0)°] was significantly lower than that of the control group[(14.0±2.2)°] at 6 months after operation (t=19.718, P<0.05). Conclusion Treatment of osteoporotic thoracolumbar vertebrae fracture with bone cement reinforced pedicle screw fixation has better clinical effect and can obviously improve the quality of life.

Objective To evaluate the clinical effect and complications of total hip replacement (THR) in novel femoral neck fracture,old femoral neck fracture, aseptic necrosis of femoral head and coxa degenerative osteoarthropathy. To provide instructions to surgical indications and treatment effects analysis.Methods One hundrde and four patients were divided into 4 groups by disease type: novel femoral neck fracture group (n = 32 ), old femoral neck fracture group (n = 22) ,aseptic necrosis of femoral head group (n =34) and coxa degenerative osteoarthropathy group (n = 16). These patients were followed-up for 12 - 144 months after THR, their Harris standard score and complications data, before and after operation, were analyzed retrospectively. Results After operation, the Harris standard scores were 92. 6 ± 5.8,90. 1 ± 5. 2,86. 3 ± 4. 6,81.9 ±4. 1 in novel femoral neck fracture,old femoral neck fracture,aseptic necrosis of femoral head and coxa degenerative osteoarthropathy groups respectively, which were significantly higher than the scores before operation (25.6±1.8,36.7±2.6,52.9±4.3,42. 1 ±3.8,Ps ＜0.05). Conclusion THR has good effects in the four types of diseases. Short length of stay and high healing rate are marked characteristics of THR. More attention shoud be paid to the complications of THR.

Objective: To explore the effect of reconstructing the finger extension function by using partial flexor digitorum profundus tendon transposition. Methods: Twelve patients were treated by using the partial proximal end of the tendon core of flexor digitorum profundus tendon regionⅠand part of region Ⅱ to cut off to the base of the distal digital phalanx, and puncturing at the end of the phalanx with a 2.0 drill. The tendon strips were pierced to the back overlap sutured to the proximal end of the avulsion of the extensor tendon . Results: In 3-18 month follow-up, the average follow-up duration was 10.6 months. According to Dargan function evaluation method, 12 cases were excellent and one case was poor. Conclusions The method of reconstructing the extensor tendon by partial flexor deep tendon is a reliable method for the treatment of Mallet finger.
