Abstract Background: When vertebroplasty is used to treat Kummell disease with bone deficiency at vertebral anterior border, bone cement displacement often occurs intraoperative or postoperative. We designed and used a new bone cement screw system to avoid the serious complication. The purpose of this study is to evaluate the safety and effectiveness of this novel operation method through more than 3 years of follow-up. Methods: From January 2012 to August 2016, 27 patients suffering from single-segment Kummell disease with bone deficiency at vertebral anterior border were treated by vertebroplasty combined with novel bone cement screw. Bone cement is released into the diseased vertebrae through screw to fully fill the intravertebral vacuum cleft. Screw fixation of bone cement can avoid intraoperative or postoperative displacement. All patients were operated by unilateral technique, only one screw was implanted for each patient. The clinical efficacy was evaluated using Odom’s criteria and statistical analysis based on the results of vertebral body index (VBI), vertebral body angle (VBA), bisegmental Cobb angle (BCA), visual analogue scale (VAS), oswestry disability index (ODI), and the MOS 36-item short from health survey (SF-36). Results: The operation was completed successfully in 27 cases. The average operation time was 49.63±10.82 min, and the average volume of cement injected was 4.70±0.87 ml. The patients’ preoperative VBI, VBA, BCA, VAS and ODI scores were 43.11±5.94, 21.04±2.55, 45.00±6.26, 7.59±0.84, and 79.85±7.58, respectively. The postoperative measurements were 78.70±2.55, 12.70±2.11, 26.11±4.73, 3.22±0.93 and 50.04±9.28. At the last follow-up, the measurements were 78.04±2.30, 13.15±2.38, 27.07±4.87, 2.04±0.65, and 22.85±5.06, respectively. There was significant difference between the preoperative and postoperative data, as well as the preoperative and the last follow-up data (P<0.05). Compared the results of SF-36 preoperative and at the last follow-up, there were significant differences in physical function, role-physical, body pain, vitality, and social function these 5 items (P<0.05). However, there were no significant differences in general health, emotional function and mental health. Finally, 26 patients (96.3%) had good to excellent clinical outcomes according to Odom's criteria. Conclusions: This 3-year follow-up study shows that the novel bone cement screw system combined with vertebroplasty has a good short and medium-term therapeutic effect on patients with Kummell disease and bone deficiency at vertebral anterior border, while its long-term efficacy is subject to further studies.

Patients with rheumatoid arthritis who had undergone total ankle arthroplasty and had a minimum of 2 yr follow-up were studied. Of the original 21 patients 17 were available for review. Twenty-three ankle replacements with an average follow-up of 5.6 yr were studied. On follow-up 2 ankles were rated excellent, 13 were rated good, 4 were rated fair, and 4 were rated poor. Thus, 83% were satisfactory on follow-up. Radiographic analysis revealed migration and settling of the talar component in 14 of 15 cases. Bone cement radiolucencies were found in 14 of 15 cases. Bone cement radiolucencies were found in 14 of 15 tibial components with tilting in 12 of these components. The postoperative position of the implant did not correlate with the development of radiolucencies or migration of the implant.

Scanning microscopy was used to study the surface of human gallstones and the surface of fractures. The specimens were obtained by operation, washed with water, dried at room temperature and shadowcasted with carbon and aluminum. Most of the specimens belong to patients from a series of X-ray follow-up study, examined during the last twenty years. So it was possible to evaluate approximately the age of these gallstones and to get information on the intensity of growing and solving.Cholesterol, a group of bile pigment substances and different salts of calcium, are the main components of human gallstones. By X-ray diffraction technique, infra-red spectroscopy and by chemical analysis it was demonstrated that all three components can be found in any gallstone. In the presence of water cholesterol crystallizes in pane-like plates of the triclinic crystal system.
