Purpose The poor prognosis in patients with floating knee injuries is mainly contributed to articular involvement(Fraser’s typeⅡ).This study aims to evaluate and compare the functional outcomes among different Fraser’s typeⅡfloating knee injuries after surgical *** Twenty-seven patients with Fraser’s typeⅡfloating knee injuries(54 fractures)between September 2014 and December 2015 were enrolled prospectively in this study and were distributed according to Fraser’s floating knee classification into three different groups as typeⅡA(ipsilateral femoral shaft and tibial intra-articular involvement,n=11),typeⅡB(ipsilateral tibial shaft and femoral intra-articular involvement,n=9)and typeⅡC(both femoral and tibial intra-articular involvement,n=7).The differences among the groups were evaluated and *** functional outcomes of these injuries at one year were analyzed using knee Injury and Osteoarthritis Outcome Score(kOOS)which covers 5 subscales of pain,other symptoms,activities of daily living,sports and recreation,and quality of *** result was also compared with standardized age-sex matched healthy population using paired samples *** All the patients were male,and the injury mechanism was solely roadside *** mean age was 29.8 years and injury severity score 17.9(comparable in all the three groups).Most injuries were observed on the right side(20 cases,74.1%).Based on paired samples t-test,the kOOS score of patients with Fraser’s typeⅡA was found to be better than that of typeⅡB and typeⅡ*** with the reference age-sex matched control group,patients with Fraser’s typeⅡB andⅡC fractures had significantly lower mean score in all kOOS subscales(all p<0.01).However,Fraser’s typeⅡA only revealed significant difference regarding the subscales of activities of daily living(p<0.0001),sports and recreation(p<0.0001),and quality of life(p<0.0001).Conclusion The results of this study show that patients with Fraser’s typeⅡA fractu

Reconstruction of chronic acromioclavicular joint disruption with artificial ligament prosthesis

引用

Chinese Journal of Traumatology 2013年第4期16卷 216-220页

作者： devendra kumar chouhan Uttam Chand Saini Mandeep Singh Dhillon Department of Orthopaedics Post Graduate Instituteof Medical Education & Research Sector 12 Chandigarh160012 India

Objective： Management of Rockwood type 3 acromioclavicular disruptions is a matter of debate. Should we adopt conservative or operative measures at first presentation？ It is not clear but most of the evidences are in favour of conservative management. We present our expe- rience in managing these patients surgically. Methods： We present a prospective series of eight cases of chronic Rockwood type 3 acromioclavicular joint disruptions treated surgically. Anatomical reconstruction of the coracoclavicular ligament was done by artificial braided polyester ligament prosthesis： Results： All the patients were able to perform daily activities from an average of the 14th postoperative day. All patients felt an improvement in pain, with decrease in ave- rage visual analogue scale from preoperative 6.5 points （range 3-9 points） to 2.0 points （range 0-5 points）, Constant score from 59% to 91% and American Shoulder and Elbow Surgeons shoulder score from 65 to 93 points postoperatively. These results improved or at least remained stationary on midterm follow-up, and no deterioration was recorded at an average follow-up of 46 months. Conclusion： This midterm outcome analysis of the artificial ligament prosthesis is the first such follow-up study with prosthesis. Our results are encouraging and justify the further use and evaluation of this relatively new and easily reproducible technique.
