Purpose : There has been considerable controversy as to the method of the treatment of acute acromioclavicular joint dislocation classified to type III injury. The purpose of this study is to compare the conservative and operative treatment of the type III acute acromioclavicular joint dislocation in terms of clinical and radiological results. Materials and Methods: We treated 31 cases of acute, type III acromioclavicular joint dislocation, 17 cases were treated by operative methods and 14 patients by conservative treatment, and 1 year minimum follow-up was done from January 1990 to January 1996. We used UCLA Shoulder Rating Scale for clinical results. And for the radiological results coracoclaviclar distance were measured. We used Fisher's exact test for statistical analysis of results between the two treatment methods. Results: Fifteen(88.2%) of seventeen patients in operative treatment and eleven(78.6%) of fourteen patients in nonoperative treatment were rated excellent or good on the UCLA rating scale. In radiographic evaluation, the average coracoclavicular distances of preoperative state, immediate postoperation(or postreduction) and last follow-up were as follows. In operative cases, it was 1.75±0.21mm, 1.14±0.24mm and 1.33± 0.22mm respectively. In nonoperative cases, it was 1.65±0.14mm, 1.26±0.26mm, and 1.42±0.27mm respectively. Conclusion : This study demonstrated that there was no significant difference in clinical and radiological results between the operative and nonoperative treatment groups. So, nonoperative treatment is recommended for acute type III acromioclavicular dislocation as general rule.

Purpose: To find out the early results after surgical treatment of the acute acromioclavicular dislocation with LIGASTIC artificial ligament. Material and Method: 6 patients who were diagnosed as acute acomioclavicular joint dislocation and treated with LIGASTIC artifical ligament through March 2005 to July 2005. The radiologic and clinical results using Imatani evaluation system were analyzed. Results: By clinical evaluation, 4 cases(67%) were excellent and 2 cases(33%) were good. By radiologic evaluation, 3 cases(50%) were excellent and 3 cases(50%) were good. All cases showed satisfactory results. Till the final follow up, there were no complication. Conclusion: Surgical treatment of the acute acromioclavicular dislocation with LIGASTIC articifial ligament is simple, but provides enough stability for early postoperative rehabilitation, decreases arthritis of acomioclavicular joint and there is no burden of removal of the fixture, so it is thought as a very effective surgery.

Background: Modified Phemister operation has been widely used for the treatment of acute acromioclavicular (AC) joint dislocation. Additionally, the use of suture anchor for coracoclavicular (CC) fixation has been reported to provide CC stability. This study was conducted to evaluate the clinical and radiological results of a modified Phemister operation with CC ligament augmentation using suture anchor for acute AC joint dislocation. Methods: Seventy-four patients underwent the modified Phemister operation with CC ligament augmentation using suture anchor for acute AC joint dislocation and were followed-up for an average of 12.3 months. The visual analogue scale (VAS), range of motion, Constant score, and Korean shoulder scoring system (KSS) were used for clinical assessment. Acromioclavicular interval (ACI), coracoclavicular distance (CCD), and acromioclavicular distance (ACD) were obtained to evaluate the radiological assessments. Results: At the last follow-up, the mean VAS Score was 1.7 points, the mean joint range of the forward flexion was $164.6^{\circ}$, external rotation at the side was $61.2^{\circ}$ and internal rotation to the posterior was a level of T12. The mean Constant score and the mean KSS was 82.7 points and 84.2 points, respectively. At the mean ACI, CCD, and ACD, significant differences were found preoperatively and at the last follow-up. When the ACI, CCD, and ACD were compared with the contralateral unaffected shoulder at the last follow-up, the affected shoulders had significantly higher values. Conclusions: The modified Phemister operation with CC ligament augmentation using suture anchor is clinically and radiologically effective at acute AC joint dislocation.

Acromioclavicular (AC) joint dislocations account for about 9% of shoulder injuries. Among them, acute high-grade injury following high-energy trauma accounts for a large proportion of patients requiring surgical treatment. However, there is no gold standard procedure for operative treatment of acute high-grade AC joint injury, and several different procedures have been used for this purpose in clinical practice. This review article summarizes the most recent and relevant surgical options for acute high-grade AC joint dislocation patients and the outcomes of each treatment type.

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 ($33.2{\pm}2.7$ vs. $31.3{\pm}3.4$, 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.

We experienced acromial erosion and subsequent fracture after the treatment of Rockwood type V acromioclavicular dislocation with hook plate and coracoclavicular ligament augmentation. It was treated by using a surgical technique to address an acromial fracture and subsequent losses of reduction in acromioclavicular joint with two trans-acromial cortical screws (crossbar technique). The reduction state of acromioclavicular joint could be maintained by these two screws. Our crossbar technique could be considered as a good salvage procedure for the reduction loss caused by cutout or significant erosion of acromion after insertion of clavicular hook plate.

The management of acute acromioclavicular dislocations has usually followed the accepted principles of obtaining an anatomical reduction of the joint and maintaining it until soft tissue healing has occurred. So, the preferred treatment for acute acromioclavicular dislocation is controversial. We analysed operatively treated twenty-eight cases for acute acromioclavicular dislocation between February 1994 and January 1997 and reviewed postoperatively to evaluate the results of three different methods. We collected retrospectively the data via clinical history, associated injury, type of injury, radiographic review, Taft score, and final results. Follow up time averaged 14 months. (range, 12 to 21 ) In according to Rockwood's classification, ]7 cases were type Ⅲ, 1 case was type IV, and 10 cases were type V. Ten cases were treated with the modified Phemister method, ten cases with the modified Bosworth method and eight cases with the modified Weaver-Dunn method. ]n patients treated by modified Phemister method, the Taft score was 9.4 points and 8 cases achieved good or excellent results. In patients treated by modified Bosworth method, the Taft score was 9.8 points and 8 cases achieved good or excellent results. In patients treated by modified Weaver-Dunn method, the Taft score was 10.3 points and 7 cases achieved good or excellent results. The overall Taft score was 9.9 points and 23 cases achieved good or excellent results. There were four complications, such as calcification or metallic loosening or breakage of K-wire, but did not influence late results. In conclusions, there was no significant difference of results regarding the different three methods. However, our results indicated that the coracoclavicular ligament reconstruction by transfer of coracoacromial ligament produced better results.
