“…The hook plate is one of the most commonly used implants for acute ACJ dislocations with good clinical and biomechanical results. 20,21) Koukakis et al 9) reported that the use of hook plate results in excellent functional outcome for the treatment of ACJ dislocations and it is suitable for inexperienced surgeons. Unlike the previously used Wolter plate, hook plates do not require drilling into the acromion and is a relatively less challenging surgical technique.…”

“…Unlike the previously used Wolter plate, hook plates do not require drilling into the acromion and is a relatively less challenging surgical technique. 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.…”

“…[6][7][8] Unlike the old Wolter plate, hook plate has been designed with an extension hook under the acromion to provide more stable fixation. 9) Its use has increased since the advent of locking plate with locking screws and good results are being reported. 10,11) But there are few reports comparing the clinical outcomes of these two techniques, and there is no report comparing two techniques in Korea.…”

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)

“…On the other hand, the technique's disadvantage is evident-it requires a second operation to remove the implant. Furthermore, this technique was usually associated with some complications, such as shoulder pain, subacromial impingement, loosening and unhooking of the plate, limited postoperative range of motion (especially abduction of the shoulder) and fractures distal to the plate [12,18].…”

Numerous procedures have been described for the operative management of acromioclavicular (AC) joint injuries. Some of these techniques, including hardware fixation and non-anatomical reconstructions, are associated with serious complications and high failure rates. Recently, AC joint reconstruction techniques have focused on anatomical restoration of the coracoclavicular ligaments to achieve optimal clinical outcomes. We used a triple endobutton technique to separately reconstruct the trapezoid and the coronoid portions of the coracoclavicular ligament. We evaluated the preliminary clinical and radiological results of this technique in patients with acute complete dislocation of the AC joint. All patients achieved a significant improvement in the pain and function of shoulder at a mean follow-up interval of 12 months (range, 8-14 months). Excellent reduction of the AC joint was maintained. The triple endobutton technique may be safe and effective for the treatment of acute complete AC joint dislocations.

“…[6][7][8][15][16][17][18] The use of AO hook plates in the treatment of dislocations is simpler and takes less time than the use of Wolter plates. In fact, Koukakis et al 19) have reported that successful treatment of acromioclavicular joint dislocation using AO hook plates is possible even if surgeons are not familiar with such cases, given they are aware of the basics of plate fixation. Henkel et al 2) carried out surgery using AO hook locking plates in ligament repair on 19 patients, of which 90% returned to work and resumed normal physical activity.…”

BACKGROUND: To evaluate clinical and radiological outcome using AO hook locking plate in acute acromioclavicular joint injuries.METHODS: This study was based on patients with Rockwood type 3 or 5 acromioclavicular joint injuries who received surgery with AO hook locking plate from June 2008 until June 2009. Among the 22 patients, 19 of them were male and 3 were female, the mean age was 44.4 +/- 15.57 years (20-72 years) and follow-up period was 15.5 +/- 3.90 months (12-23 months). Preoperatively, postoperatively, and at the final follow-up after the plate removal, both coracoclavicular distances were measured from the anteroposterior radiograph. Also, the Shoulder Rating Scale of the University of California at Los Angeles scores (UCLA scores), the American Shoulder and Elbow Surgeons scores (ASES scores), Constant scores, and the Korean Shoulder Society scores (KSS scores) were measured at the final follow-up to evaluate the function of the shoulder joint.RESULTS: At the time of injury, the mean coracoclavicular distance of the injured side was 17.69 +/- 4.23 mm (9.57-27.82 mm) and the unaffected side was 7.55 +/- 2.20 mm (3.24-13.05 mm). The mean coracoclavicular distance measured postoperatively and at the final follow-up was 6.87 +/- 2.34 mm (4.07-14.13 mm) and 8.47 +/- 2.96 mm (4.37-17.48 mm), respectively. The mean UCLA, ASES, Constant, and KSS scores measured in the final follow-up were 33.5 +/- 1.30 (31-35), 90.8 +/- 8.36 (72-100), 78.6 +/- 8.80 (62-100), and 94.4 +/- 5.08 (84-100) each.CONCLUSIONS: From this short-term research, the surgical treatment using AO hook locking plates in acute acromioclavicular joint injuries is clinically and radiographically satisfying and considered as a useful treatment method.
