On the 3D reformatted CT images, sagittal curvature angle of the ulnar coronal process (△1), tangent angle of the coronal process apex to olecranon fossa (△2), projective length (L) and projective height (H) were measured; the transverse width of the coronal process was also measured at 5 mm and 10 mm from the tip (K1 and K2). The minimum value was used for △2° in order to avoid cutting into the joint while the mean value for other parameters. After the shape of the plate and angles of the screws were designed using computer 3D software, a new anatomic plate for coronal process was produced. Five cadaver specimens were used to test the internal fixation of the coronal process with our novel anatomic bone plate. Attachment of the bone plate to the coronal process and screw penetration into the joint cavity were observed by X-ray and 3D CT scanning. \u0000 \u0000 \u0000Results \u0000△1 was 45.52°±6.07°, △2 65.25°±7.09° (the minimum value 53.2°), L 52.27±7.78 mm, H 21.62±2.63 mm, K1 16.32±2.22 mm and K2 14.58±2.18 mm. Our new anatomic bone plate was designed based on the above data. X-ray and 3D CT scan after plate internal fixation showed that our self-designed bone plate produced fine attachment and no screws penetrated into the joint. \u0000 \u0000 \u0000Conclusion \u0000Our new anatomical bone plate may perfectly fit the anatomy of the adult ulnar coronal process in size and shape so that the coronary process can be fully covered and no screws will penetrate into the joint cavity. \u0000 \u0000 \u0000Key words: \u0000Bone plate; Elbow Joint; Anatomy; Cadaver","PeriodicalId":10145,"journal":{"name":"Chinese Journal of Orthopaedic Trauma","volume":"21 1","pages":"901-905"},"PeriodicalIF":0.0,"publicationDate":"2019-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42233606","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}

They were 16 males and 3 females with the average age of 36.2 years (from 22 to 57 years). According to Stephens-Sanders classification, the malunion was defined as type Ⅰ in 10 cases, as type Ⅱ in 6 and as type Ⅲ in 3.

Of the 30 recommendations, 26 obtained recommendation from these experts at a rate of above 95%, and 4 recommendation from these experts at a rate from 80% to 90%. The rates of strong recommendation were not high, ranging from 60% to 80% in 26 recommendations and <60% in 4. \u0000 \u0000 \u0000Conclusions \u0000The recommendations from the above 2 documents have been highly agreed upon by these experts we investigated but obtained a relatively low rate of strong recommendation. The present investigation may serve as a significant complement for recommendations from the 2 documents of expert consensus and a necessary reference for orthopaedic surgeons. \u0000 \u0000 \u0000Key words: \u0000Questionnaires; Ankle joint; Radius; Enhanced recovery after surgery; Expert consensus","PeriodicalId":10145,"journal":{"name":"Chinese Journal of Orthopaedic Trauma","volume":"21 1","pages":"864-868"},"PeriodicalIF":0.0,"publicationDate":"2019-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43347420","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}

They were divided into 2 groups according to the different reduction methods. The reduction was assisted by a double-needle repositor in 37 cases (group A); they were 21 males and 16 females with an age of 46.2±8.1 years and there were 13 cases of Garden type Ⅲ and 24 cases of Garden type Ⅳ. The reduction was conducted manually in another 30 cases (group B); they were 18 males and 12 females with an age of 48.8±9.1 years and there were 13 cases of Garden type Ⅲ and 17 cases of Garden type Ⅳ. The 2 groups were compared in terms of reduction time, anatomical reduction rate, operation time, intraoperative bleeding volume, fracture healing time, postoperative complications and Harris hip scores at the last follow-up. \u0000 \u0000 \u0000Results \u0000There were no significant differences between the 2 groups of patients in their preoperative general data, indicating they were compatible(P>0.05). All the 67 patients were followed up for 20 to 30 months (average, 24 months). The anatomic reduction rate in group A [94.6% (35/37)] was significantly higher than that in group B [83.3% (25/30)]; the reduction time, operation time and fracture healing time in group A (33.2±4.6 min, 70.2±5.0 min and 4.6±0.7 months) were significantly shorter than those in group B (45.8±8.6 min, 90.6±9.2 min and 5.6±0.6 months); the Harris hip scores at the last follow-up in group A (84.3±8.6 points) were significantly higher than in group B (81.2±7.8 points) (all P 0.05). \u0000 \u0000 \u0000Conclusion \u0000Reduction assisted by a double-needle repositor is fine for femoral neck fractures of Garden types of Ⅲ-Ⅳ, because it has advantages of limited invasion, simplicity, a high rate of anatomical reduction, quick reduction and good functional recovery. \u0000 \u0000 \u0000Key words: \u0000Femoral neck fractures; Fracture fixation, internal; Bone nails; Reduction; Double-needle repositor","PeriodicalId":10145,"journal":{"name":"Chinese Journal of Orthopaedic Trauma","volume":"21 1","pages":"758-763"},"PeriodicalIF":0.0,"publicationDate":"2019-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45843691","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}
