Observation Of Clinical Efficacy Of Suture Button Plate Versus Clavicular For Acute Unstable Acromioclavicular Joint

【Objective】To investigate the clinical efficacy of loop plate system in the treatment of fresh Acromioclavicular dislocation of Rockwood III and above with minimally invasive microincisions compared with traditional clavicular hook plates with internal fixation.Explore the pros and cons of both treatments.【Methods】Choose between January 2015 and November 2020,Dali university first affiliated hospital of the acromioclavicular joint dislocation admitted in orthopaedic trauma patients in 45,retrospective case control study,in which 22 cases with traditional treatment clavicular hook plate(group A),23 cases with loops plate technology treatment(group B),two groups of patients with preoperative in gender,age,injury parting comparable,respectively on two groups of patients with intraoperative blood loss,operative time,length of hospital stay,postoperative complications and beak lock,the distance between two groups of patients after surgery for 4 weeks left forearm condole belt suspension and brake,In addition,early functional rehabilitation exercises were conducted.Meanwhile,visual analogue Scale(VAS)and postoperative shoulder Constant score under different surgical methods were compared.The reduction loss was measured according to the X-ray reexamination of the patients on the third day and 12 months after the operation.After collecting complete data,SPSS 25.0 was used for corresponding statistical analysis.【Results】In terms of incision length,intraoperative blood loss and operation time,the incision length of loop plate(5.6±0.5cm)was smaller than that of clavicular hook plate(8.5±1.9cm)in the two groups,with statistically significant difference(P < 0.01).However,the upper loop plate(80.7±27.1min)was longer than the clavicular hook plate(49.6±20.9min),and the difference was statistically significant(P < 0.01).There was no significant difference in intraoperative blood loss between the two(P > 0.05).In terms of length of stay,the length of stay of patients treated with loop steel plate(12.9±5.1 days)was shorter(P < 0.05)and patients treated with loop steel plate could recover physical labor earlier(P < 0.01).There was no significant difference in VAS score between the two groups before surgery(P > 0.05).At 12 months after surgery,the pain score of loop plate group(1.2±0.3)was still smaller than that of clavicular hook plate group(1.5±0.4),showing a statistically significant difference(P < 0.05).When the clavicular hook plate was removed,the pain score of the patients was compared with that of the patients treated with loop plate(12 months after the operation),and the difference was not statistically significant(P < 0.05).In terms of the Constant score 12 months after surgery,there was no statistically significant difference in muscle strength score between the two groups(P > 0.05),and the upper loop plate group was superior to the clavicular hook plate group in pain score,daily activity score and shoulder range of motion score(P < 0.01).In terms of therapeutic effect,X2 test showed that: the curative effect of loop steel group was significantly higher than that of steel group(P < 0.05).The loop steel plate group(150.0±2.0°;Compared with the clavicular hook plate group(136.8±5.7°),(101.6±11.6°).Lifting94.3±8.1° in abduction was more advantageous(P < 0.01).Three months after the removal of clavicular hook plate,there was still a difference in activity between the loop plate group(12 months after the operation)(P < 0.01).【Conclusion】Traditional loops of clavicular hook plate and steel plate for the treatment of patients with acute acromioclavicular joint dislocation can achieve satisfactory clinical effect,loops steel belongs to elastic fixed,on the function more in line with the biomechanics of the acromioclavicular joint structure,for pain relief and recovery of function has more obvious advantages,also do not need a second surgery to take out the characteristics of internal fixation,but the loops plate technology required for operation time is long,difficult operation,intraoperative blood loss,compared with traditional clavicular hook plate,though without secondary surgery took out a reset after the probability of loss is high.
