They were 114 males and 66 females, aged from 16 to 83 years (average, 47.6 years). The levels of plasma D-dimer were detected at admission, one day preoperation, and 1, 3, 5 days postoperation. B-ultrasound examination of both lower extremities was performed before and after surgery. According to the results of B-ultrasound, the patients were divided into a DVT group and a non-DVT group. The 2 groups were compared in the plasma D-dimer levels measured at different time points. DVT risk factors were screened by univariate analysis, and multivariate logistic regression analysis was used to determine independent risk factors. \u0000 \u0000 \u0000Results \u0000Of this cohort, 54 cases (30%) developed DVT and 39 cases (21.7%) did preoperation. Of the 39 cases (mixed DVT in one and distal DVT in 38 ones), DVT disappeared in 14 postoperation. Of the 40 cases (22.2%) of postoperative DVT (proximal DVT in one, mixed DVT in one and distal DVT in 38 ones), 15 developed newly postoperation. Multivariate logistic regression analysis showed that age, time from injury to operation, pre-operative and postoperative D-dimer elevation were independent risk factors for DVT in the patients. The D-dimer levels in the DVT group were significantly higher than in the non-DVT group at one day preoperation, and 1, 3, 5 days postoperation (P<0.05). The area under the receiver operating characteristic curve was 0.704. When the critical value of D-dimer was 1.4 mg/L, its sensitivity for DVT diagnosis was 0.944 and its specificity 0.246 (poor). When the concentration of D-dimer was 4.45 mg/L, its sensitivity for DVT diagnosis was 0.574 and its specificity 0.817 (the highest). \u0000 \u0000 \u0000Conclusions \u0000Perioperative DVT may happen in patients with tibiofibular fracture, mostly at the distal end beyond the popliteal vein. Clinically, patients who are advanced in age, have plasma D-dimer elevation at admission and after operation, and have waited long for operation should be alert to the occurrence of DVT. The plasma D-dimer level with a recommended threshold of 4.45 mg/L may have a certain diagnostic value for patients with tibiofibular fracture. \u0000 \u0000 \u0000Key words: \u0000Tibia; Fibula; Fractures, bone; Deep vein thrombosis; Risk factors; D-dimer","PeriodicalId":10145,"journal":{"name":"Chinese Journal of Orthopaedic Trauma","volume":"21 1","pages":"952-958"},"PeriodicalIF":0.0,"publicationDate":"2019-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44952942","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 83 males and 76 females with a mean age of 42.6 years (from 14 to 79 years). They were divided into 2 groups according to their range of motion at the latest follow-up and the secondary elbow arthrolysis they had undergone or not. The stiffness group had extension-flexion and/or pronation-supination <100° and secondary elbow arthrolysis while the non-stiffness group had extension-flexion and pronation-supination ≥100° and no secondary elbow arthrolysis. Age, gender, fracture side, mechanism of injury, AO fracture classification, open/close fracture, additional fracture, preoperative nerve injury, time from injury to surgery, surgical approach, configuration of plating, medication for anti-heterotopic ossification and implant removal were analyzed as risk factors for elbow stiffness using Logistic regression analysis. \u0000 \u0000 \u0000Results \u0000The mean follow-up period for this cohort was 32.0 months (from 10 to 63 months).

They were divided into 2 groups by their treatment methods. In the 9 patients treated by instrumentation with 3D-printed patient-specific guides, there were 6 males and 3 females with an age of 54.6±8.6 years, 4 left and 5 right sides involved, and one case of Takakura stage 1, 3 cases of Takakura stage 2 and 5 cases of Takakura stage 3a.

The distribution of the insertion and starting points, appearance and attachment area of the trapezium and conical ligaments were observed. The lengths of the 2 ligaments, the coronal and sagittal lengths of the clavicular attachment area, the distances from the most lateral point to the distal end of the clavicle, and the angles at the coronal and sagittal positions of the 2 ligaments were measured. Subsequently, the 12 cadaveric specimens were randomly divided into 4 groups (n=3). Group A retained the intact acromioclavicular ligament, group B the intact coracoclavicular ligament, group C the intact trapezium ligament and group D the intact conical ligament. In an electronic machine for versatile mechanical tests, a 100 mm/min load speed was applied for destructive static stretching of the ligament specimens in the vertical direction. The load-displacement curves were recorded and drawn by a computer in connection with the biomechanical testing machine. The rupture strengths of the 4 ligaments were recorded. \u0000 \u0000 \u0000Results \u0000The average lengths of the conical and trapezium ligaments were 10.6 mm and 12.5 mm, respectively.

The coronal and sagittal lengths of the clavicular attachment area of the trapezium ligament averaged 14.2 mm and 8.7 mm, respectively. The distances from the most lateral points of the conical and trapezium ligaments to the distal clavicle averaged 35.5 mm and 23.6 mm, respectively. The average angles at the coronal and sagittal positions were 6.2° and 11.3° for the conical ligament and 38.7°and 6.9° for the trapezium ligament, respectively.

Collected were their baseline parameters including age, gender and American Society of Anesthesiologists (ASA) scores, preoperative blood parameters including coagulation indicators [D-Dimer, fibrinogen degradation product (FDP), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), international normalized ratio (INR) and thrombin time (TT)] and platelets indicators, and fracture parameters including number of fractured vertebrae and duration of fracture. The 2 patients groups were divided into 5 age groups: 4 age groups for each 10 between 50 and 90 years and one age group for >90 years. The values of D-Dimer and FDP were compared between the 2 patient groups in each corresponding age group.

According to the Pauwels classification, there were 24 cases of type Ⅰ, 16 cases of type Ⅱ and 7 cases of type Ⅲ; according to the Garden classification, there were 23 cases of type Ⅱ, 19 cases of type Ⅲ and 5 cases of type Ⅳ. All the fractures were immobilized with KHS after closed reduction or open reduction (3 cases). The fracture union time, femoral head necrosis and femoral neck shortening were observed after operation. The Harris scores were used to evaluate therapeutic effects at the final follow-up. \u0000 \u0000 \u0000Results \u0000All the patients were followed up for an average of 29.7 months (from 22 to 39 months). All the fractures obtained solid bony union after 9 to 15 weeks(average, 12.2 weeks). Femoral head necrosis occurred in one case (2.1%). Femoral neck shortening ≤ 5 mm was observed in 6 cases and femoral neck shortening >5 mm <10 mm in 2 cases, giving a total shortening rate of 17.0%. The Harris scores at the final follow-up ranged from 77 to 98 points, averaging 92.2 points. There were 42 excellent, 3 good and 2 moderate cases, giving an excellent and good rate of 95.7%. \u0000 \u0000 \u0000Conclusion \u0000KHS can lead to excellent therapeutic effects in the treatment of femoral neck fractures. \u0000 \u0000 \u0000Key words: \u0000Femoral neck fractures; Fracture fixation, internal; Bone plates; Therapeutic effect","PeriodicalId":10145,"journal":{"name":"Chinese Journal of Orthopaedic Trauma","volume":"21 1","pages":"939-944"},"PeriodicalIF":0.0,"publicationDate":"2019-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41498121","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}
