The frequency of reduction loss after arthroscopic fixation of acute acromioclavicular dislocations using a double-button device, and its effect on clinical and radiological results

Abstract

Background: The aim of this study was to investigate the effect of reduction loss of more than 3 mm on clinical and radiological results after at least 2 years of follow-up after arthroscopic fixation of acute acromioclavicular joint dislocations using a double-button device. Methods: Thirty-six patients who had acute (< 3 weeks old), type III or V acromioclavicular (AC) joint dislocations underwent arthroscopic fixation of the AC joint using a double-button device. Clinical and radiological evaluations were performed at preoperative, postoperative first day, 3 months and last follow-up. When the coracoclavicular (CC) distances of patients at the last follow-up were compared to the early postop CC distances, those with a difference of 3 mm or less were grouped as group A and those with a difference of more than 3 mm were grouped as group B.

Mid-term clinical and sonographic outcomes of minimally invasive acromioclavicular joint reconstruction: mini-open versus arthroscopically assisted

“…Our absolute values at follow-up are comparable to data in the literature, with a certain loss of reduction being known to occur with different techniques [ 5 , 36 , 37 ]. In line with our data, a recent systematic review could not detect significant differences between open and arthroscopic ACJR techniques in terms of loss of reduction and complication rate [ 37 ].…”

Assessment of Coracoclavicular Ligament Healing on MRI After Arthroscopic TightRope Fixation for Acute Acromioclavicular Joint Dislocation

“…The most common injury mechanism in our study was traffic accidents (57.5%). However, in their studies of patients with acute AC dislocation, Çarkçı et al 8 and Olivos-Meza et al 26 stated that most injuries were sports-related (41.7% and 40.3%, respectively). We found Rockwood type 5 injuries in 24 (72.7%) patients, with a male predominance of 87.8%, which matches the findings of the previous studies.…”

“…We found Rockwood type 5 injuries in 24 (72.7%) patients, with a male predominance of 87.8%, which matches the findings of the previous studies. 8 , 26 Olivos-Meza et al 26 found that patients in whom reduction was preserved had a shorter interval to surgery than those with failed reduction ( t = 14.6; P = .0001), and the investigators advocated for early surgical intervention (before 3 weeks) to facilitate AC joint reduction. Our study disclosed a mean time elapsed before surgery of 5.3 days (range, 2-14 days), which was close to the values of Çarkçı et al 8 (6.7 days) and Olivos-Meza et al 26 (12.8 days).…”

Clinical and radiological outcome of acute high-grade acromioclavicular joint dislocation: A retrospective cohort study on Hook plate versus arthroscopic assisted single coracoclavicular tunnel with DogBone™ button dual FiberTape® construct

“…Similar categorization of CCD was performed by Çarkçı et al to assess differences in clinical scores in patients with higher loss (>3 mm) in reduction compared to lesser loss (<3 mm). 15 The subacromial osteolytic zone, if present, was measured in AP view of shoulder immediately after the HP removal and again, at last, follow up to assess its continuation or resolution. The axillary view was utilized to assess the quality of reduction in the horizontal plane.…”
