Application Of Suture Anchor Combined With Allograft Tendon For The Treatment Of Acromioclavicular Joint Dislocation

Objectives Application of suture anchor combined with allograft tendon for thetreatment of acromioclavicular joint dislocation, hope for the acromioclavicular jointdislocation provide clinical evidence for the selection of surgical method.Methods In this article, through the method of retrospective study, the second hospital ofarmed police corps in Beijing orthopaedics between September2011and September2011admitted during the period of23cases of the acromioclavicular joint dislocation of patients,on the basis of clinical manifestation, imaging diagnosis, for fresh closed completelydislocation; Respectively using suture anchor, combined with allograft tendon for thetreatment of acromioclavicular joint dislocation and the aged>50line, theacromioclavicular joint surface damage serious clavicle distal resection, preoperative andpostoperative follow-up of all patients in the process of clinical manifestation and X-rayanalysis, respectively, the Constant-Murley score (CMS) and Karlsson standard evaluationof shoulder joint function; Using SPSS13.0statistical software package for data processing,and carry on objective scientific and reasonable analysis, the final results and conclusions.Results (1)All patients received follow-up follow-up time7to25months, an average of16months. All patients without infection, rejection, loose suture anchor, emergence andtail line, allogeneic tendon rupture complications. Preoperative CMS42~82points, withan average of62.61±9.85points, the optimal0cases, good in2cases,15cases,6cases;Qualitative evaluation Karlsson curative standard:0cases,7cases,13cases.3monthsafter the CMS65~96, an average of88.04±8.59points, compared with preoperative hasimproved significantly (t=-18.908, P <0.05), including14cases, good in5cases, can bein2cases,2cases, the treatment was82.6%(19/23); Karlsson is obviously better than thestandard after preoperative, of which15cases,6cases,2cases, the treatment was91.3%(21/23).(2)Including2patients in postoperative3months review the acromioclavicularjoint is reset when the part is missing, when no or only slight shoulder joint pain,discomfort, but at the time of the last follow-up shoulder joint range is no obvious changeafter, only on the X ray film of beak lock gap widened the postoperative had mild, distalclavicle slightly upward, but puffed up less than half the diameter of the clavicle,postoperative follow-up of3months CMS score and Karlsson standard evaluation for good, after the opinions from patients, no further treatment.(3)And2patients with ipsilateralmultiple fractured ribs conservative treatment, and patients with primary injury, failed toearly dislocation of acromioclavicular joint surgery. Shoulder joint activity by his greatchest, small muscles and the shoulder sleeve bearing, pull the chest wall, limited activity,missed the early function exercise of prime time. Two patients respectively in16days afterinjury,19days of dislocation of acromioclavicular joint surgery, postoperative follow-upof3months follow-up shoulder joint was up to120°or loading on shoulder joint pain, inaccordance with CMS and Karlsson standard are evaluated for the poor.Conclusions Application of suture anchor combined with allograft tendon anatomicreconstruction of beak lock ligament for the treatment of acromioclavicular jointdislocation, has a small surgical trauma, biology fixation, early functional exercises, fewercomplications, etc. Fixed the acromioclavicular joint is not strong, around the back jointanatomy and biomechanical function at the same time, makes the acromioclavicular jointand between coracoid process and clavicle can still keep certain micro, avoids theacromioclavicular joint fixed "fixed" too much happening, has obvious biomechanicaladvantage; Without traditional slip of internal fixation, fracture, rejection reaction, goodhistocompatibility, biological adaptability, can be reserved for a long time in the body donot have to remove secondary surgery. Cooperate with early functional exercise, can makethe shoulder joint restore to its original function.
