Suture augmentation of acromioclavicular and coracoclavicular ligament reconstruction for acute acromioclavicular dislocation.

ABSTRACT

ABSTRACT The objective of this report was to introduce a new suture augmentation of coracoclavicular (CC) and acromioclavicular ligament reconstruction for acute Rockwood grade III to V acromioclavicular dislocations.From January 2015 to January 2019, 43 patients with Rockwood III to VI acute acromioclavicular dislocations were retrospectively reviewed. For comparison, another series of 28 patients treated with double Endobutton technique from January 2011 to December 2014 were reviewed. A P < .05 was considered statistical significance.The mean follow-up period of the 2 series were 39.69 ±â€Š7.42 months (range, 24-54 months) and 37.86 ±â€Š8.23 months (range, 26-48 months) (P > .05), respectively. There were significant differences regarding CC space (11.62 ±â€Š2.54 mm vs 16.78 ±â€Š5.53 mm; P < .05), CC reduction loss (5.56 ±â€Š4.73 mm vs 26.25 ±â€Š4.42 mm; P < .05), and acromioclavicular space (6.89 ±â€Š1.87 mm vs 7.95 ±â€Š2.37 mm; P < .05). There were significant differences regarding the disabilities of the arm, shoulder, and hand questionnaire (3.3 ±â€Š2.8 vs 5.32 ±â€Š4.37; P < .05) and University of California-Los Angeles shoulder rating scale (31.19 ±â€Š2.48 vs 29.24 ±â€Š2.48; P < .05). The excellent to good percentages were 100% (n = 32) and 85% (n = 23), respectively.In conclusion, the suture augmentation of acromioclavicular and CC ligament reconstruction is a reliable technique for acute acromioclavicular dislocation with minimal complications.Type of study/level of evidence Therapeutic IIa.
