Objective To analyze and compare the effectiveness of the closed reduction with elastic intramedullary nail ing and open reduction with Kirschner wire fixations in the treatment of O’Brien type III radial neck fractures in children. Methods Between November 2007 and November 2010, 31 children with O’Brien type III radial neck fractures were treated by the closed reduction with elastic intramedullary nailing fixation (closed reduction group, n=18) and by the open reduction with Kirschner wire fixation (open reduction group, n=13). There was no significant difference in age, gender, disease duration, and fracture classification between 2 groups (P gt; 0.05). Results The incisions of 2 groups healed primarily. Allthe patients were followed up 1-2 years (mean, 1.5 years). Limitation of the elbow extension occurred in 2 cases of the closed reduction group, l imitations of the elbow extension, flexion, and forearm pronation in 6 cases of the open reduction group. There was no significant difference in elbow flexion, extension, pronation, and supination between affected side and normal side in the closed reduction group (P gt; 0.05). Except in supination (P gt; 0.05), there were significant differences in flexion, extension, and pronation between affected side and normal side in the open reduction group (P lt; 0.05). According to Metaizeau’s grading criterion, excellent results were achieved in 16 cases and good in 2 cases in the closed reduction group; excellent results were achieved in 4 cases, good in 4 cases, fair in 3 cases, and poor in 2 case in the open reduction group; and there was significant difference between 2 groups (Z=3.435, P=0.001). The X-ray films showed anatomical reduction in 2 groups before removal of internal fixation; redisplacement occurred in 4 cases after removal of internal fixation in the open reduction group, no redisplacement occurred in the closed reduction group. There was no avascular necrosis of radial head and epi physes during follow-up. Conclusion Comparison with the open reduction with Kirschner wire fixation, the closed reduction with elastic intramedullary nailing fixation is a rel iable and good treatment for O’Brien type III radial neck fractures in children, because it has the advantages of minimal invasion, easy operation, stable fixation, early mobilization, and less complication.
Objective To compare the efficacy of plating versus intramedullary nailing in the treatment of adult humeral shaft fracture. Methods We identified eligible studies in PubMed (1950 to September 2007), MEDLINE (1950 to September 2007), OVID CINAHL (1950 to September 2007), OVID EBM (3rd Quarter 2007), CBMdisk (1978 to June 2007) and CNKI (1981 to June 2007). We also handsearched several Chinese orthopedic journals. Data were extracted and evaluated by two reviewers independently. Randomized controlled trials (RCTs) comparing plating versus intramedullary nailing for humeral shaft fracture in adults were included and the quality of these trials was critically assessed. Data analyses were conducted with Stata 10.0. Results Six RCTs involving 425 patients were included, among which the statistical heterogeneity was not significant (Pgt;0.1). Cumulative meta-analyses showed that intramedullary nailing might increase the re-operation rate in studies conducted before the year of 2000 (OR=0.39, 95%CI 0.17 to 0.90, P=0.03), but the difference was not significant in studies conducted after 2000 (OR=0.54, 95%CI 0.27 to 1.08, P=0.08). Intramedullary nailing might increase the incidence of shoulder impingement compared with plating (OR=0.13, 95%CI 0.03 to 0.65, P=0.01). The rates of non-union, deep infection, iatrogenic radial nerve injury and internal fixation failure were similar between plating and intramedullary nailing. Meta-analyses were not conducted for union time, operation time and bleeding (transfusion) volume, because the relevant data were not available from the included trials. Conclusion Intramedullary nailing may increase the incidence of shoulder impingement. The rates of re-operation, non-union, deep infection, iatrogenic radial nerve injury and internal fixation failure are similar between plating and intramedullary nailing. Further well-designed and large-scale randomized controlled trials are required to determine the effects of plating and intramedullary nailing on these outcomes.
ObjectiveTo evaluate the effectiveness of titanium elastic nails for severe displaced proximal humeral fractures in older children. MethodsBetween April 2009 and July 2012, 31 cases of severe displaced proximal humeral fractures were treated with closed or open reduction and fixation with 2 titanium elastic nails, and the clinical data were retrospectively analyzed. There were 23 boys and 8 girls, aged from 10 to 15 years (mean, 12.8 years). The causes of injury were sports injury (16 cases), traffic accident (11 cases), and falling from height (4 cases). The interval from injury to operation was 6 hours to 7 days (mean, 72 hours). According to Neer-Horwitz classification, 17 cases were rated as type III fracture and 14 cases as type IV fracture. There were 21 cases of metaphyseal fractures and 10 cases of epiphyseal fractures. ResultsSatisfactory reduction of fracture and stable fixation were obtained in all patients (closed reduction in 23 cases and open reduction in 8 cases). Primary healing was achieved in all incisions; no infection and neurovascular injury occurred. All patients were followed up 12-36 months with an average of 20 months. X-ray films showed that all fractures healed at 7-10 weeks (mean, 8 weeks). During follow-up, no disturbance of development or angulation deformity caused by premature physeal closure or bone bridge formation was observed. At last follow-up, the average Neer score of the shoulder was 95.7 (range, 83-100). The appearance and motion of the shoulder were normal. There was no significant difference in the upper extremity length between affected side and contralateral side[(67.68±2.56) cm vs. (67.61±2.54) cm; t=-1.867,P=0.072]. ConclusionTitanium elastic nails for severe displaced humeral fractures in older children is a safe and effective method with a low complication incidence.
ObjectiveTo compare the effectiveness of locking compression plate and elastic intramedullary nail for the treatment of benign long bone pathological fractures in children, so as to provide the evidence for clinical treatment. MethodsSeventy-two children with long bone pathological fractures who accorded with the inclusion criteria between January 2005 and July 2013 were randomly divided into 2 groups. Fracture was fixed with elastic intramedullary nail in 33 cases (group A) and with locking compression plate in 39 cases (group B). There was no significant difference in sex, age, body mass index, primary lesion, location of fracture, side of fracture, and interval between injury and operation between 2 groups (P>0.05). ResultsGroup A had shorter operation time, less intraoperative blood loss, and less overall costs than group B, showing significant differences (P<0.05). Primary healing of incision was obtained. All the patients were followed up 1-7 years (mean, 3.4 years). Tumor lesions disappeared and the pathological fracture healed after operation by X-ray film observation, and group A had faster fracture healing time than group B (P<0.05). There was no loosening and displacement of internal fixation, bone resorption, and bone defect nonunion in 2 groups. Recurrence was found in 2 cases (6.1%) of group A and 3 cases (7.7%) of group B, showing no significant difference (χ2=0.074, P=0.580). Re-fracture was found in 1 patient with tibial bone cyst of group B after 3 months of operation, and healed after 1 year of open reduction and internal fixation. According to X-ray film and comprehensive function evaluation of shoulder, elbow, hip, knee, and ankle, the results were all excellent in 2 groups at last follow-up. ConclusionElastic intramedullary nail fixation should be the first choice, and locking compression plate should be the second choice for children with benign long bone pathological fractures.
