Application of shoulder arthroscopy-assisted acromioclavicular joint low-notch titanium plate system in patients with acromioclavicular joint dislocation
Objective To explore the effects of arthroscopic assisted low incision loop titanium plate system on pain severity,shoulder joint function,and levels of cortisol(Cor)and adrenocorticotropic hormone(ACTH)in patients with acromioclavicular dislo-cation.Methods Eighty-two patients with acromioclavicular joint dislocation admitted to the Affiliated Traditional Chinese Medicine Hospital,Southwest Medical University were selected.The patients were divided into a study group and a control group using random number table method,41 in each group.The study group was treated with arthroscopic assisted low incision loop titanium plate system.The control group was treated with open reduction and clavicular hook steel plate internal fixation.The pain level,shoulder joint function,and levels of Cor and ACTH at different time points after surgery were compared and analyzed between the two groups.Results The excellent rate of surgery in the study group was higher than that in the control group(P<0.05).On the first day after surgery,the levels of Cor and ACTH in both groups were higher than those before surgery,but the study group was lower than the control group(P<0.05).All shoulder joint function scores in the study group were higher than those before surgery(P<0.01).After 4 weeks and 6 months of surgery,the visual analogue scale(VAS)scores,daily activities,shoulder joint range of motion score in the study group were higher than those in the control group.After 6 months of surgery,the shoulder joint strength test scores of the study group was higher than those of the control group(P<0.01).Conclusions The treatment of acromioclavicular dislocation with low incision titanium plate system assisted by arthroscopy can effectively alleviate the pain degree,improve the joint function and stress re-sponse.The treatment has a definitely clinical efficacy.
