“…9,22) Recently, locking plates shaped as conventional hook plates but with locking screws are being commonly used, and good results are being reported. [6][7][8] An advantage of the hook plate is the relatively easy implantation procedure and early postoperative mobilization. 23) However, serious complications from the hook plate including subacromial impingement and pathologic acromial fractures require attention.…”

Background: Kirschner's wire (K-wire) transfixation and locking hook plate fixation techniques are widely used in the treatment of acute acromioclavicular joint (ACJ) dislocation. The purpose of this study was to compare the clinical and radiologic outcomes between K-wires transfixation and a locking hook plate fixation technique. Methods: Seventy-seven patients with acute ACJ dislocation managed with K-wire (56 shoulders) and locking hook plate (21 shoulders) were enrolled for this study. The mean follow-up period was 61 months. Results: At the last follow-up, the shoulder rating scale of the University of California at Los Angeles (UCLA) was higher in patients treated with locking hook plate than with K-wires (33.2 ± 2.7 vs. 31.3 ± 3.4, p=0.009). In radiologic assessments, coracoclavicular distance (CCD) (7.9 mm vs. 7.7 mm, p=0.269) and acromioclavicular distance (ACD) (3.0 mm vs. 1.9 mm, p=0.082) were not statistically different from contralateral unaffected shoulder in locking hook plate fixation group, but acromioclavicular interval (ACI) was significant difference. However, there were significant differences in ACI, CCD, and ACD in K-wire fixation group (p<0.001). Eleven complications (20%) occurred in K-wire transfixation group and 2 subacromial erosions on computed tomography scan occurred in locking hook plate fixation group. Conclusions: ACJ stabilization was achieved in acute ACJ dislocations treated with K-wires or locking hook plates. Locking hook plate can provide higher UCLA shoulder score than K-wire and maintain CCD, and ACD without ligament reconstruction. K-wire transfixation technique resulted in a higher complication rate than locking hook plate. (Clin Shoulder Elbow 2014;17(4):159-165)

“…Moreover, transarticular fixation using an HP may induce bony osteolysis, shoulder impingement, and rotator cuff damage, leading to poor functional results. 15,21) Considering the advantages and disadvantages of these two surgical methods, there is little radiologic and clinical outcome evidence regarding the management of acute highgrade AC joint injuries using HP vs. the tight rope (TR) method. Therefore, we compared the clinical and radiologic outcomes of the locking HP fixation technique with those of the single TR technique for treatment of acute high-grade AC joint separations.…”

Background: This study was conducted to compare the clinical and radiological outcomes of the locking hook plate fixation (HP) technique and the single tight rope (TR) technique applied for acute high-grade acromioclavicular (AC) joint separations. Methods: Between 2009 and 2014, 135 consecutive patients with acute AC joint separation Rockwood types III, IV, and V were subjected to surgical reconstruction. One hundred fourteen patients (84.4%) were available for retrospective evaluation. Of them, 62 and 52 were treated using the single TR group and clavicular HP group techniques, respectively. The visual analogue scale, Constant, American Shoulder and Elbow Surgeons (ASES), and Taft scores were used for clinical assessment. Postoperative shoulder range of motion was also assessed. An anteroposterior radiograph of the coracoclavicular distance (CCD) was obtained to evaluate the radiographic signs of recurrence. Results: The TR group patients had better Constant, ASES, and Taft scores than the HP group patients. The loss of reduction in terms of the CCD did not differ between groups. Subacromial osteolysis was observed in 34.6% of the cases in the HP group. However, there were no significant differences in the clinical outcomes between the patients with and without osteolysis in the HP group. Subcoracoid osteolysis, drill tunnel widening, and metal displacement were observed in 3.2%, 22.6%, and 4.8% of the cases in the TR group, respectively. Conclusions: The single TR technique was relatively more effective at treating acute high-grade AC joint injuries than the HP fixation technique (level of evidence: therapeutic; retrospective comparative study, Level III).

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.
