A Comparison of Results between AO Hook Plate and TightRope for Acute Acromioclavicular Joint Dislocation

Abstract

Results:Comparing the functional results, no differences were observed between the two groups (Constant score: HP, 78.5; TP, 81.4; UCLA score: HP, 29.2; TP, 29.9; KSS: HP, 79.2; TP, 80.7). Time to restoration of the range of motion (ROM) above shoulder level was longer in the HP group than in the TR group. However, the ROM at 1 year postoperation and final follow-up revealed similar results between the two groups. The AC joints were well reduced in both groups, the CCD increased to 44.7% in the HP group and to 76.5% in the TR group at the final follow-up; however, no one was significantly superior to the others. Furthermore, there were 8 cases (25.0%) and 5 cases (26.3%) of AC joint arthritis in the HP group and TR group, respectively. However, the observed AC joint arthritis has a poor correlation between clinical symptom and radiological results in both groups. Conclusion:Both HP and TR fixation could be a recommendable treatment option in acute unstable AC joint dislocation. Both groups showed excellent radiologic and functional results at the final visit. Moreover, there was no significant difference in statistics, except for the time to restoration of ROM above shoulder level.

Combination of Clavicular Hook Plate with Coracoacromial Ligament Transposition in Treatment of Acromioclavicular Joint Dislocation

“…The follow-up cases also showed a high recovery rate, and it was therefore approved by most of the surgeons. We performed the same plate fixation to maintain the stability of the AC joint in 25 patients 7 .…”

“…However, scholars have been inclined to apply surgical methods to patients with Rockwood type III-V dislocation. In recent years, advantages like easy operating, higher joint mobility and clavicle-like design have been well-recognized by the orthopaedists when using internal fixation with clavicular hook plate for treating patients with moderate or severe AC joint dislocation 6,7 . However, the internal fixation alone without ligament repair and construction may not be sufficient to maintain the stability of AC joint and will result in a high recurrence rate of dislocation 8 .…”
