Methods: Anatomical study and a test method were applied to 43 cadavers of both sexes. During the period between 2000 and 2013, 34 patients of both sexes were operated upon using the new method. In the comparison group(n = 120), the fixation of the acromial extremity of the clavicle rupture was performed with hamate plate, Lee hook and Kirschner wires.Results: Its application allows, according to the evaluation scale of Constant and Murley(1987), 10% more preservation of the function of the shoulder compared with traditional methods of surgical treatment, and shortens the required hospital treatment and temporary disability periods.Conclusions: It is shown that the proposed author's method combines low invasiveness, minimum dimensions of the construction and low-cost treatment.展开更多

It has rare clinical syndrome, such as forehead radius, small maxilla ofa cial, wide long distance eye, collapse nose, widening cranial suture, incompleted closure of the frontal, clavicle hypoplasia, increased range of shoulder motion and other abnormalities. Often accompanied by teeth hypoplasia or impacted, through a careful observation of the clinical morphology, case history and X-ray examination can confirm the diagnosis.展开更多

Patients were followed up for 12 months, thereafter, various indicators including operative indexes, Constant-Murley (CM) score, disability of arm shoulder and hand (DASH) score, activities of daily living (ADL), and complications were compared between groups.Results: The incision length, intraoperative blood loss, operation time, and fracture healing time of the observation group were significantly lower than the control group (P<0.05). The postoperative CM scores of the two groups were significantly increased, moreover, the scores of muscle strength, daily life and activity were significantly in the observation group were higher than those of the control group (P<0.05), and no difference was found in the pain degree (P>0.05). There was a decrease trend in the DASH score and an increase trend in the ADL score in both groups, while both indexes were better in the observation group than in the control group (P<0.05). The total incidence of complications in the observation group was significantly lower than that in the control group (8.33% vs 18.75%,P<0.05).Conclusion: Compared with the reconstruction plate fixation, locking compression plate internal fixation has the advantages of more mini invasive, better amelioration of shoulder joint function and less complication for patients with mid-shaft clavicular fractures.展开更多
