There were 19 males and 6 females, aged 48-76 years (mean 60.1±7.0 years). Cervical spinal cord function was assessed using the Japanese Orthopaedic Association (JOA) spinal cord function score, and the rate of improvement in neurological function was calculated. The quality of life of patients was assessed using the neck disability index (NDI). Axial symptoms were assessed and indexed using the visual analog scale (VAS). The C0-2 angle of the cervical spine was measured by X-ray preoperative and at the last follow-up. The cervical curvature was evaluated by the C2-7 angle, and the cervical vertebra activity was observed by the dynamic X-ray of the cervical spine. \u0000 \u0000 \u0000Results \u000025 patients were followed up for a period of 26-64 months (mean 35.9±8.1 months). At the last follow-up, the JOA score was 14.32±3.24, the NDI score was 7.61±1.23, and the VAS score was 1.42±0.78. The differences between the three scores were statistically significant compared with the preoperative scores. The neurological improvement rate at the last follow-up was 79.61%±13.23%. The preoperative C0-2 angle was 26.04°±6.28°, and the last follow-up was 24.92°±5.51°; the C2-7 angle was 19.55°±9.42° before surgery, and the C2-7 angle at last follow-up was 17.97°±8.80°. The C2-7 angle at last follow-up was slightly reduced compared with that preoperative, but the difference was not statistically significant. The preoperative cervical vertebra ROM was 35.31°±12.24°, and at the last follow-up it was 32.23°±9.65°. The ROM of cervical vertebrae at the last follow-up was slightly lower than that before surgery, but the difference was not statistically significant. Among them, the reduction of the ROM of overflexion was greater than that of the over-extension, which was the main reason for the decrease of ROM. The OPLL bone mass continued to grow at the last follow-up of 11 patients. \u0000 \u0000 \u0000Conclusion \u0000The extended to C1, 2 posterior single-door laminoplasty for the treatment of ossification of the posterior longitudinal ligament combined the upper cervical spine can achieve adequate spinal cord decompression, satisfactory neurological improvement, and improve the postoperative cervical curvature and activity.

With the development of tissue engineering, the strategies and methods for repairing osteochondral defects in the past decade have made great progress, and some osteochondral tissue stratified stent products have gradually entered the clinical trial stage.. The related articles on tissue engineering for the treatment of osteochondral defects were retrieved by searching databases with key words osteochondral defects, cartilage repair and hierarchical scaffolds. This paper discussed the research status of hierarchical scaffolds in osteochondral tissue engineering during recent five years. In this work, the classification of hierarchical scaffold including monophasic scaffolds, bilayered scaffolds, multilayered scaffolds and gradient scaffolds, are summarized by comparing different experiment researches. Furthermore, the advantages and disadvantages of different types of hierarchical scaffolds were introduced through analyzing relevant studies. Monophasic scaffolds can support the adhesion and proliferation of osteoblasts and chondrocytes, but lack the inherent stratified structure features required for osteochondral regeneration.. Bilayered scaffolds consist of a chondral layer and subchondral layer which base on the biocompatibility of monophasic scaffolds. Biphasic scaffolds are significantly better than monophasic scaffolds in simulating natural cartilage, but the interface between chondral and subchondral layer is poor binding. Compared with bilayered scaffold, trilayered scaffolds are added with an intermediate layer which simulates the calcification of normal cartilage between the two layers, so as to obtain better connection of the bone and cartilage layer. Unlike hierarchical scaffolds, gradient scaffolds provide a gradient connection between the layers, which is more similar to the native osteochondral tissue. In the past five years, the development of osteochondral layered scaffolds mainly depended on the novel structure and fabrication methods of scaffolds. However, correlational clinical studies are quite few. Further high quality and large clinical studies are still required.","PeriodicalId":36405,"journal":{"name":"中华骨科杂志","volume":"39 1","pages":"1413-1420"},"PeriodicalIF":0.0,"publicationDate":"2019-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48384811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Main fracture lines were concentrated in the area on the dorsal side of the central area and the scaphoid area. The fracture lines of type B fracture mainly concentrated in scaphoid region, which accounted for 29.85% (20/67), and dorsal side and central area accounted for 26.87% (18/67). The fracture lines of type C fracture accounted for 27.46% (39/142) in scaphoid area and 31.69% (45/142) in central area. The fracture line of type C fracture increased in the lumbar fossa region (17.61%, 25/142) and the lower ulnar region (12.68%, 18/142) compared with type B fracture (28.69%).

There were 7 males and 4 females with an average age of 41.2 years old (range, 25-67 years). Injuries were caused by falling down in 7 cases, traffic accident in 3 cases, and falling from height in 1 case, respectively. On the basis of Luo's three columns classification in tibial plateau, there were 9 cases of medial column fracture and 2 cases of medial combined with posterior column fracture. Six cases were concomitant with fibular head fracture and 2 cases with the injury of common peroneal nerve. Preoperative magnetic resonance imaging showed that there were anterior cruciate ligament injury in 3 cases, posterior cruciate ligament injury in 4 cases, medial meniscus injury in 5 cases, lateral meniscus injury in 3 cases, medial collateral ligament injury in 6 cases, iliotibial band injury in 2 cases and posterolateral complex injury of the knee joint in 9 cases, respectively.

They were randomly divided into four groups: continuing immobilization group, instant micromovement group, 1-week micromovement group and 2-week micromovement group. Postoperative radiographs were taken at 1, 2, 3 and 5 weeks to observe callus growth. The maximum load, deflection and rigidity of callus at fracture end were measured 5 weeks after operation. At 1, 2 and 3 weeks after operation, the histological morphology of callus was observed, and the expression and distribution of osteocalcin (oc) in callus were detected. \u0000 \u0000 \u0000Results \u0000At 5 weeks after operation, the X-ray scores of fracture line in 1-week micromovement group and 2-week micromovement group were 10.384±0.744 mm, 10.412±0.482 mm, significantly higher than those in continuing immobilization group (7.518±0.536). The anteroposterior diameter and the exterior and interior diameter of the external callus in 1-week micromovement group and 2-week micromovement group were 14.3±3.2 mm, 14.0±2.8 mm and 14.6±2.1 mm, 15.2±3.1 mm, which were smaller than those in the continuing immobilization group 15.3±2.3 mm and 16.7±1.9 mm, but there was no significant difference. The bone mineral density value and proportion rate in the fracture site were 0.446±0.020 g/cm2, 0.416±0.021 g/cm2 and 1.171%±0.056%, 1.143%±0.040% in 1-week micromovement group and 2-week micromovement group, which were significantly higher than those in continuing immobilization group which were 0.376±0.022 g/cm2 and 0.912%±0.051%.

There was no difference of the deflection of callus between groups. The rigidity of callus in 1-week micromovement group was 590.4±24.2 N/mm, which was significantly higher than that in other groups; the rigidity of callus in the 2-week micromovement group was 540.6±22.8 N/mm, which was significantly higher than those in the instant micromovement group and the continuing immobilization group (152.4±21.7 N/mm, 174.8±20.6 N/mm). \u0000 \u0000 \u0000Conclusion \u0000Micromovement begins from one or two weeks can significantly raise external callus formation and vagueness level of fracture line, accelerating bridging callus formation, and can significantly raise bone mineral density and rigidity of callus. It also accelerates the maturity, hypertrophy and mineralization of chondrocyte, resulting in the stimulation of the fracture healing through endochondral ossification; it seemingly can improve the amount and density of osteoclasts in callus to stimulate the maturity and mineralization of chondrocyte.

Now,these ankle fracture eponyms are still found in medical literature, textbooks and even mass media. Many special named ankle fractures can be explained by the Lauge-Hansen classification now, and they may have little practical use. However, it is still necessary to summarize and review these ankle fracture eponyms, in order to correct the wrong usage of these and to remember the sages in this field.We reviewed both common and less frequently used ankle fracture eponyms, focusing on imaging features to identify and differentiate these injuries.

Methodological Indexfor Non-randomized Studies (MINORS) was used to evaluate the quality of the literatures. The meta-analysis was performed using Review Manager 5.3 and Stata 15.0 statistical software. \u0000 \u0000 \u0000Results \u0000A total of 35 literatures were included, including 22 English literatures and 13 Chinese literatures. There were 3 630 patients with 45.2% of males, aged from 14 to 89 years old (mean, 62.6 years). The average of length of stay (LOS), operation time (OT) and blood loss (BL) of OLIF procedure were 6.7 days, 117 minutes, and 128 ml, respectively. The VAS scores of low back pain of postoperative and final follow-up decreased by 4.33 and 4.70, respectively. The VAS scores of leg pain decreased by 4.57 points and 5.31, respectively. Compared with preoperative, the postoperative JOA score increased by 7.58 and the postoperative ODI were also improved by 33.89%. All the postoperative imaging data were significantly different from those before surgery. The surgical level intervertebral heightincreased 4.14 mm, and the intervertebral foramen height and intervertebral foramen area increased by 3.54 mm, 53.96 mm2, while the dura sac cross-sectional area increased by 36.61 mm2, and the overall lumbar lordosis increased by 13.78° with the local segmental lordosis increased by 4.62°. The overall incidence of complications of OLIF was 32%, with a 95% confidence interval of 25%-38%. \u0000 \u0000 \u0000Conclusion \u0000OLIF is a minimally invasive procedure for the treatment of lumbar degenerative diseases. OLIF has a simply procedure and short learning curve, with short LOS and operation time, less blood loss. OLIF can effectively open the narrow intervertebral space and increase the spinal canal and nerve root canal, significantly improve the symptoms, while the complication rate is low, so OLIF is worthy of widespread clinical application. \u0000 \u0000 \u0000Key words: \u0000Lumbar vertebrae; Spinal fusion; Meta-analysis","PeriodicalId":36405,"journal":{"name":"中华骨科杂志","volume":"39 1","pages":"1320-1332"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49068964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
