HU Wei,LEI Tao,TANG Jun, et al. Comparative study of small incision tightrope system and clavicular hook plate in the treatment of acromioclavicular joint dislocation[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2018, 48(8): 595-599.
Abstract:Objective: To compare the clinical efficacy of small incision tightrope system and AO hook plate in the treatment of Rockwood type III acute shoulder dislocation. Methods: From January 2014 to December 2016, 69 cases of Rockwood type III acromioclavicular joint dislocation were treated in the Orthopedics Department of the Second Affiliated Hospital, Wenzhou Medical University. Among them, 30 cases were treated with small incision tightrope system and 39 with AO clavicle hook plate. The indexes of their postoperative imaging results, clinical outcomes and complications during operation and hospitalization between the two groups of patients were compared and analyzed. Results: Compared with the clavicle hook plate group, the operation time of the small incision tightrope plate group was the same (P>0.05), but the average blood loss was less and the length of incision was shorter (P<0.05). There was no significant difference (P>0.05) between the two groups in the beak lock distance. The incidence rate of shoulder pain in the small incision tightrope plate group was lower than that of the clavicle hook plate group, and there was no significant difference between the two groups in the Constant function of the shoulder joint (P>0.05). Dislocation occurred in 3 cases of small incision tightrope plate group. In clavicle hook plate group, postoperative complications occurred including skin irritation, wound infection and nerve injury. Conclusion: The overall efficacy of small incision tightrope plate in the treatment of Rockwood type III acromioclavicular joint dislocation is comparable to the clavicle hook plate. However, small incision tightrope plate has advantages in terms of minimal invasive surgery, low incidence rate in postoperative shoulder pain and shoulder joint activity limit, and less complications as well.
