coracoclavicular ligament by suspensory fixation to manage the acute acromioclavicular
joint dislocation.
Methods: From January 2016 to December 2017, 18 cases of acute acromioclavicular joint
dislocation were carried out with arthroscopic reconstruction of coracoclavicular ligament
by double Endobutton plate suspensory fixation. Anteroposterior view X-ray plain
radiographs were obtained on the second day, 6 months and 12 months after the surgery,
MRI was performed in 1 year after operation. Meanwhile, subjective and objective scoring
were obtained by Vsual Analogue Scale (VAS), Rating Scale of the American Shoulder and
Elbow Surgeons (ASES) and University of California at Los Angeles Shoulder Rating
Scale (UCLA).
Results: All patients were followed up for 12 to 30 months (an average of 18 months).
There was no patient with infection, neurovascular injury, loosening and breakage of
internal fixation, re-dislocation of acromioclavicular joint, clavicular fracture, coracoid
process fracture, etc. Postoperative X-ray showed that all acromioclavicular joints were
completely relocated. The follow-up of MRI after 1 year showed no obvious dislocation of
acromioclavicular joint and good recovery of acromioclavicular space. Postoperative
shoulder joint function, VAS, ASES, UCLA and acromioclavicular distance were
significantly improved compared with those before surgery, with statistically significant
differences (all P<0.05).
Conclusion: Arthroscopic reconstruction of coracoclavicular ligament by suspensory
fixation to manage the acute acromioclavicular joint dislocation has the advantages of
minimal invasive, rapid functional recovery and less complications and satisfactory early
clinical results.
