Objective To summarize the basic research and the cl inical appl ication of biodegradable interbody fusion Cage. Methods Recent l iterature concerning biodegradable interbody fusion Cage at home and abroad was extensively reviewed, and current developments of the basic research and the cl inical appl ication of biodegradable interbody fusion Cage were investigated. Results Basic research showes that the stiffness of biodegradable interbody fusion Cage is lower than that of metall ic Cage, so it can enhance interbody fusion. As interbody fusion proceeded, biodegradable interbody fusion Cage degrades constantly, but the speed of degradation can not keep in parallel with that of fusion. In addition, the tissue response to degradation products is controversy. Cl inical appl ication showes that the biodegradable interbody fusion Cage can enhance interbody fusion and maintain disc space height. The short term results are good, however, the long term results need further observation. Conclusion Biodegradable interbody fusion Cage can effectively enhance interbody fusion.
In order to solve the defect of blood vessel in tissue transplantation and complicated palmar amputation, bridge by "Y" type vein had been used from Jan. 1990 to Jul. 1996. Twenty-three cases were treated. In this series, there were 16 males and 7 females, with ages ranged from 10 to 42 years old. Six cases were the defect of lower legs anterior skin and tibia, 3 cases were the femur fracture with injury of femoral artery and tissue’s defect, 2 cases were defect of five fingers, 12 cases were complicated palmar amputation. RESULT: 15 cases with tissue transplantation and 12 cases with limb replantation were all survival without infection or necrosis. After the following-up for 3 years (ranged from 1 to 5 years), the function of injured limbs were satisfactory, 19 patients had resumed their original work. So, to bridge by "Y" type vein is a good method for repairing the defect of blood vessels in tissue transplantation and complicated palmar amputation, but skilled microsurgery technique is required.
ObjectiveTo evaluate the clinical results of the self-manufactured screw director of the calcaneous sustentaculum tali in the surgical treatment of intra-articular calcaneal fractures. MethodsBetween May 2012 and October 2013, 40 patients (47 feet) underwent surgical treatment of intra-articular calcaneal fractures, and the clinical data were analyzed. There were 29 males and 11 females with an average age of 46 years (range, 25-68 years). According to Sanders classification, 17 feet were rated as type Ⅱ, 20 feet as type Ⅲ, and 10 feet as type IV. The average time from injury to admission was 6.02 hours (range, 1-12 hours). All the patients were treated with the screw director of the calcaneous sustentaculum tali to fix the sustentaculum tali. The intraoperative times of fluoroscopy were recorded. The Böhler angle and Gissane angle were measured at pre- and post-operation. The clinical functional outcomes were evaluated according to the Maryland foot score system. ResultsThe intraoperative times of fluoroscopy were 2-4 times (mean, 2.85 times). Radiographic examination showed 45 screws were accurately implanted into the middle of the sustentaculum tali in implanted 47 screws except 1 screw which penetrated into the anteroinferior of the sustentaculum tali and 1 screw which penetrated into the anterior of the sustentaculum tali. The accurate rate of screw implant was 95.7%. All patients were followed up for an average of 12 months (range, 8-18 months). During the follow-up, incision skin necrosis and infection occurred in 2 cases, and sural nerve injury developed in 3 cases. Bone union was achieved at an average of 12.72 weeks (range, 9-18 weeks) postoperatively. The Böhler angle was improved significantly from (6.48±3.67)° pre-operatively to (29.40±4.65)° post-operatively (t=-31.38, P=0.00). The Gissane angle was improved significantly from (99.30±5.85)° pre-operatively to (130.84±5.08)° post-operatively (t=-28.32, P=0.00). The Maryland foot score was 90.66 on average (range, 65-98) at last follow-up; the results were excellent in 41 feet, good in 3 feet, and fair in 3 feet with an excellent and good rate of 93.6%. ConclusionThe self-manufactured screw director of the calcaneous sustentaculum tali can significantly improve the accuracy of the screw implanted into the sustentaculum tali and reduce the harm of intraoperative fluoroscopy to the body.
Artificial intelligence (AI) has been widely used in all walks of life, including healthcare, and has shown great application value in the auxiliary diagnosis of pulmonary nodules in the medical field. In the face of a large amount of lung imaging data, clinicians use AI tools to identify lesions more quickly and accurately, improving work efficiency, but there are still many problems in this field, such as the high false positive rate of recognition, and the difficulty in identifying special types of nodules. Researchers and clinicians are actively developing and using AI tools to promote their continuous evolution and make them better serve human health. This article reviews the clinical application and research progress of AI-assisted diagnosis of pulmonary nodules.
