Using Endobutton Plate With Clavicl Hook Plate In The Treatment Of Chronic Acromioclavicular Jiont Dislocation

Objective:On the chronic acromioclavicular joint dislocation,we explore a simple operation,fixed indeed,postoperative functional recovery satisfactory treatment: chronic acromioclavicular joint dislocation treatd with endobutton plate with clavicular hook plate internal fixation,and notarize the methods to meet the basic requirements of acromioclavicular dislocation treatment,and to promote.Methods:Retrospective analysis of our hosipital from September 2014 to September 2016,11 patients with chronic acromioclavicular joint dislocation were treated with open reduction and internal fixation with endobutton plate with clavicular hook plate.All of these patients are included in the study,who consist of 8 male-patients and 3 female-patients.Among them,5 had left chronic acromioclavicular joint dislocation and 6 had right.They were average 47.6 years of age,aged 28-62.All of them were closed injury.There were 8 Rockwood-III and 3 Rockwood-V.And according to Tossy classification,there were 11 Tissy type III.All patiens were adopted antibiotic within 24-72 hours,using shoulder-elbow suspension splint within 4 weeks,adoped continuous passive motion and active motion from professional rehabilitation doctor within 3-4 weeks,avoided strenuous exercise within 3mouths after the operations.Retrospective analysis of 11 patients undergoed operation time,intraoperatve blood volum,and shoulder functional recovery time and effect.The Karlsson score was used to quantify the functional of the shoulder afteroperation.Result:1.11 patients’ operation time was 35-60 min,average time 45.2±5.7min,and intraoperatve blood volum 30-110 ml,average volum 50±22.3 ml.2.All of 11 patients were followed,follow-up time 3-6 mouths(average4.7 mouths).The postoperation radiocarpal joints and muscles around shoulder were recovered well,recovery time 2-3 mouths(average time 2.5mouths).There were no cromioclavicular jiont dislocation,and no lossening,falling off and breaking of internal fixation.3.According to the Karlsson score,there were 8 perfects and 3 goods,Bs reach 100%.4.Compared the postoperative effects of Rockwood-III and 3Rockwood-V,there are no difference.5.11 patients with acromioclavicular joint stability and good activity without acromioclavicular joint dislocation removed clavicular hook plate after 6 months.Conclusion:It,using endobutton plate with clavicl hook plate in the treatment of chronic acromioclavicular jiont dislocation,eases the problem of stress concentration because of using clavicl hook plate solely,effectively reduces fracture-rates of clavicl hook plates.Building coracoclavicular ligament replacement with endobutton plate avoids the complicated problem of ligament reconstruction operation,ligamentous laxity forward,and part loss of reduction.Simple operation,less time,less bleeding,short hospital stays and better prognosis,all of which are conducive to promote the technique.
