XU Fangzao,WANG Gencun. Early removal feasibility of hook plate for acromioclavicular joint dislocation[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2021, 51(11): 920-923.
Abstract：Objective: To explore the feasibility of early removal of the hook plate of the acromioclavicular joint and its therapeutic effect. Methods: Clinical data of 32 patients with acromioclavicular joint dislocation treated in our hospital from January 2017 to December 2019 were retrospectively analyzed. Results: Thirtytwo patients completed the initial internal fixation implantation, regular follow-ups and internal fixation removal in our hospital. The VAS pain score of the patients in the 6-month removal group was significantly higher than that in the over-6-month removal group (4.58±1.08 vs. 2.20±1.36, P<0.001). The shoulder function score of the patients in the 6-month removal group was 72.92±7.13, significantly lower than that of the patients in the over-6-month removal group (80.50±5.58, P=0.002). When the plate was removed, no significant difference was found in VAS pain score and shoulder function score between both groups. There was no significant difference in the widening distance of coracoclavicular joint space between the two groups after the removal of internal fixation[(1.70±1.19)mm vs. (2.20±2.02)mm, P=0.442]. Conclusion: Early removal of internal fixation after hook plate fixation of acromioclavicular joint dislocation can relieve the patients of pain, discomfort and functional limitation without increasing the re-dislocation risk of the acromioclavicular joint.
