BACKGROUND:Bone cement used in the vertebroplasty treatment of osteoporotic vertebral compression fractures is nonabsorbable and has stronger intensity than normal bone tissue, which can cause further fractures of adjacent segments. OBJECTIVE:To investigate the short-term effect of vertebroplasty with artificial bone in the treatment of osteoporotic thoracolumbar fractures. METHODS:A total of 21 patients with osteoporotic vertebral compression fractures were enrol ed, including 7 males and 14 females, aged 61-89 years old. Al the patients were subjected to vertebroplasty with calcium sulfate injection. Visual analog scale and Oswestry Disability Index assessment were used before and at 0, 24, 48 weeks after treatment;meanwhile, X-ray and CT were used to observe the fil ing and leakage of artificial bone. RESULTS AND CONCLUSION:After treatment, al the patients showed improvements in the scores of visual analog scale and Oswestry Disability Index (P<0.01). X-rays and CT scans showed that there were three cases of leakage but without spinal cord and nerve compressions. After 3 months, most of the artificial bone was absorbed. These findings indicate that vertebroplasty with artificial bone can ease pain and improve living conditions of patients with osteoporotic vertebral compression fractures.

BACKGROUND: Hip arthroplasty is now an effective method of effectively solving the problem of femoral neck fracture in the elderly, but there is a risk of big trauma, high joint dislocation and postoperative complications. OBJECTIVE: To explore the application value of 3D printing guide plate in hip arthroplasty in the elderly by retrospective study and literature retrieval. METHODS: (1) Clinical data of 25 elderly patients with femoral neck fracture undergoing hip arthroplasty from February 2017 to October 2018 in Liaoning Jinqiu Hospital were retrospectively analyzed. In the guide plate group, 13 patients received hip arthroplasty using 3D printing guide plate. In the non-guide plate group, printing guide plate was not used in 12 cases. The application value of SuperPATH technique with 3D printing guide plate in hip arthroplasty in the elderly was observed. (2) Wanfang database was retrieved by the first author for studies published from 2000 to 2019. The key words were “3D, hip”. According to the inclusion criteria, 31 articles were selected to analyze the application value of 3D printing guide plate in hip arthroplasty in the elderly. RESULTS AND CONCLUSION: (1) The results of retrospective analysis showed that the operation time and the times of X-ray fluoroscopy were less in the guide plate group than those in the non-guide plate group (P < 0.05). Intraoperative blood loss and Harris score of hip function at the final follow-up were not significantly different between the two groups (P > 0.05). (2) Literature search results showed that 3D guide plates could be used to compensate for some defects of surgery in hip arthroplasty. There are many approaches to implement joint arthroplasty. Both conventional and minimally invasive approaches have direct anterior approach and posterolateral approach. According to several literature analysis, direct anterolateral approach can reduce trauma, and minimally invasive approach can reduce the risk of surgery. The above results show that the use of 3D printing guide plate in elderly hip arthroplasty can reduce the operation time and the times of intraoperative X-ray fluoroscopy, and the effect is better. 3D guide plate has application value in hip arthroplasty, and it has advantages in combination with minimally invasive techniques.

Objective:To analyze the curative effect of arthroscopic debridement combined with extracorporeal shock wave therapy in the treatment of knee osteoarthritis. Methods:All cases were divided into 2 groups:the control group were treated with arthroscopic debridement,the treatment group were treated with arthroscopic debridement combined with extracorporeal shock wave therapy. The Lysholm score and VAS score was used to determine the changes in patients. Results:After 1 months and 3 months, Lysholm score in the two groups of patients was higher than that before operation (P<0.05) . Lysholm score in the treatment group were higher than that in the control group, VAS score was lower than that in control group (P<0.05) . After 6 months, Lysholm score and VAS score showed no significant difference in 2 groups (P>0.05) . Conclusion:Arthroscopic debridement combined with extracorporeal shock wave therapy in early stage can achieve the functional recovery and pain-relief effect, can better improve the patient's joint function and quality of life.
