A Comparison of Results between AO Hook Plate and TightRope for Acute Acromioclavicular Joint Dislocation: Yong Gun Kim, Ho Jae Lee, Dong Won Kim, Jinmyoung Dan; J Korean Fract Soc 2017;30(1):16-23. Published online January 31, 2017; DOI: https://doi.org/10.12671/jkfs.2017.30.1.16

PURPOSE
The purpose of our study is to compare the radiographic and clinical outcomes with respect to acromioclavicular (AC) joint dislocation depending on the surgical method: Hook plate (HP) versus TightRope (TR).
MATERIALS AND METHODS
Between May 2009 and May 2012, 51 patients with Rockwood type III-V lesions received clinical and radiographic follow-up. Patients were divided into two groups according to the surgical methods (HP: n=32; TR: n=19). Radiological follow-up included comparative coracoclavicular distance (CCD) measurements as a percentage of the uninjured shoulder. For clinical follow-up, a standardized functional shoulder assessment with the Constant score, University of California at Los Angeles (UCLA) score, and Korea shoulder score (KSS) were carried out.
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.

Abstract PDF

PURPOSE
To evaluate the clinical and radiologic results of the arthroscopic treatment using TightRope(R) (Arthrex, Inc, Naples, FL) for management of acute acromioclavicular dislocation.
MATERIALS AND METHODS
Twelve patients with acromioclavicular joint dislocation Rockwood type V are underwent the arthroscopic acromioclavicular joint reconstruction using TightRope(R) between March, 2008 and March, 2009. The average age was 40.4 years (range 25~63 years) and mean follow-up was 10 months (range 8~16 months). The shoulders were evaluated using parameters include radiologic measurements by comparing the clavicle posteroanterior and lateral radiographs with the contralateral one. Clinical evaluation was made for pain, function, and range of joint motion by Constant score and KSS (Korean Shoulder Score).
RESULTS
All twelve patients returned to their work without pain in 3 months after operation. The average Constant score and KSS score was 98.4 (range 97~100) and 97.8 (range 97~100) at the last follow-up. Because of technical error and indication error, two patients showed failures of TightRope(R) fixation on the coracoid side and the acromioclavicular joint was redislocated, so these cases were excluded. 10 patients were satisfied with functional results and cosmetic appearance.
CONCLUSION
Considering its less morbidity, less hospitalization, excellent cosmesis, early rehabilitation, this new technique offers an attractive alternative in acromioclavicular joint stabilization if the early technical error would be overcome.

Modified Spring Plate for Treatment of Unstable Distal Clavicle Fractures: Sang Myung Lee, Il Jung Park, Hyung Min Kim, Jae Chul Park, Sung Gil Cho, Yoon Chung Kim, Seung Koo Rhee; J Korean Fract Soc 2010;23(1):64-68. Published online January 31, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.1.64

Abstract PDF: PURPOSE
Unstable distal clavicle fractures should be treated surgically but may be difficult in firm fixation because of small distal fragment. Although a variety of fixation methods have been currently used, none of the methods seem to be firm fixation and little pain. We present a new technique using a spring plate which was modified from one third tubular plate and report the early results.
MATERIALS AND METHODS
Modified spring plate was made from one third tubular plate and the distal hole of the plate was cutting and sharpened by rasp. The sharp edge was bent just like an animal claw (C shape). Between May 2007 and June 2009, a total of six patients with distal clavicle fracture were treated using modified spring plate. A sling was applied in the immediate post operative period for six weeks and exercises were started immediately.
RESULTS
Union was achieved in all cases with excellent results without complication (mean Constant score, 96). All patients had returned to ordinary daily activities but mild limitation of abduction (150 degrees ) by seven weeks after surgery. After six months, the plate was removed.
CONCLUSION
The modified spring plate has provided stable fixation for unstable distal clavicle fixation without disturbance to the acromioclavicular joint, subacromial space, or rotator cuff.

Long Term Follow up Results of the Operative Treatment of the Acromioclavicular Joint Dislocation with a Wolter Plate: Ki Ser Kang, Han Jun Lee, Jae Sung Lee, Jae Yoon Kim, Yong Beom Park; J Korean Fract Soc 2009;22(4):259-263. Published online October 31, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.4.259

Abstract PDF

PURPOSE
To evaluate the long-term clinical and radiological results of the operative treatment of the acromioclavicular dislocation with a Wolter plate. MATERIALS AND METHODS: We reviewed clinical and radiological data of twenty patients (mean age: 37 years) who underwent the operative treatment of acromioclavicular joint dislocation using a Wolter plate from September, 1999 to December, 2002 with minimum of five years follow-up (average 6 years 7 months). The clinical outcomes of twenty patients were evaluated by UCLA scoring and radiological results of fifteen patients with available radiograph were evaluated by Zanca view and stress view. RESULTS: The mean UCLA score was mean 33 points (range, 27~35) at final follow up. By clinical evaluation, twelve cases (60%) were excellent, six cases (30%) were good and two cases were poor (10%). By radiological evaluation, eight cases (54%) were excellent (without displacement), five cases (33%) were good (displacement <5 mm) and two cases (13%) were poor (displacement >5 mm). Erosive change in acromioclavicular joint was seen in poor case. CONCLUSION: Wolter plate fixation may be a useful modality for treating acromioclavicular joint dislocation. Great care should be taken to make the hook hole at the appropriate position during operation for long-term prognosis.

Result of Wolter Plate Fixation for the Treatment of Dislocation of Acromioclavicular Joint and Clinical Importance of Coracoclavicular Ligament Repair: Jang Suk Choi, Ki Young Kim, Kyong Chil Chung, Heui Chul Gwak, Dong Jun Ha, Kyoung Whan Kim; J Korean Fract Soc 2006;19(1):41-45. Published online January 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.1.41

Abstract: PURPOSE
To evaluate the clinical result of the Wolter plate fixation for the acromioclavicular joint dislocation and the necessity of coracoclavicular ligament repair with the operation.
MATERIALS AND METHODS
Twenty three patients operated between January 2003 to September 2005 with over 6 months of follow-up period were studied. The Constant-Murley scoring system was administered on 6 months postoperatively and stress films were taken for the surveillance of acromioclavicular joint and coracoclavicular distance after plate removal. All patients were classified into two groups in that coracoclavicular ligament was repaired (10 cases) or not (13 cases) and the clinical indices described above were compared.
RESULTS
With the Wolter plate fixation for the acromioclavicular joint dislocations, 20 cases of Constant-Murley scores were more than 'good' except complicated 3 cases. The scores of the repaired group were 7 cases of excellent, 2 cases of good and 1 case of moderate to poor, and that of not-repaired group were 6 cases, 5 cases and 2 cases respectively. With mean coracoclavicular interspace on x-ray at postoperative 6 months, repaired group showed residual 9% of displacement from initial 194% but not-repaired group showed 28% from initial 188%. There's no statistically significant difference in clinical scores between two group (p=0.072) and neither was residual coracoclavicular interspace displacement (p=0.067).
CONCLUSION
Short term follow-up of Wolter plate fixation for the acromioclavicular dislocation showed acceptable clinical results and there was no statistically significant difference between two groups of repaired coracoclavicular ligaments and not repaired.

Modified Phemister Technique with Mersilene Tape Augmentation in the Acute Acromioclavicular Joint Dislocation: Hyun Dae Shin, Kwang Jin Rhee, Young Mo Kim, Kyung Cheon Kim, Choong Hui Lee; J Korean Fract Soc 2005;18(2):83-88. Published online April 30, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.2.83

Abstract PDF: PURPOSE
To find out the consequences of the surgical treatment of acromioclavicular joint dislocation, using modified Phemister technique with Mersilene tape augmentation.
MATERIALS AND METHODS
We chose 26 patients who were able to follow up 1 year or more among the patients who were diagnosed as acromioclavicular joint dislocation in our hospital through February 2001 to March 2003 and took modified Phemister surgery with Mersilene tape augmentation. Patients with clavicle fracture were excluded. Evaluation of the surgical results was done with the condition or pain, function, range of motion by using Imatani evaluation system, and preoperative, postoperative and last follow up radiographs.
RESULTS
Most of the cases showed satisfactory result. Clinical evaluations were 16 excellent (62%), 10 good (38%), radiological evaluations were 14 excellent (54%), 10 good (38%), 2 fair (8%), and no poor group. On the final follow up six cases showed vertical translation, but none had clinical symptoms. Seven cases showed a little inflammation at where pin were inserted, but after the removal of the pin, the inflammation was gone.
CONCLUSION
The modified Phemister surgery for acromioclavicle dislocation is simple, but we can obtain strong fixation, and there is no burden of the removal of the metal plate, or complication of re- dislocation after the removal of the pin, so it is thought as a very effective surgery.

The Treatment of Acromioclavicular Dislocation Comparison Study between Bosworth Screw and Wolter Plate Technique: Jae Do Kang, Kwang Yul Kim, Hyung Chun Kim, Kyung Chil Jung, Mun Sup Lim, Jin Hyung Kim, Seong Joo Lee; J Korean Soc Fract 2003;16(4):548-554. Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.548

Abstract PDF: PURPOSE
Acromioclavicular joint dislocation are frequently seen and various operation treatment modalities have been suggested. The purpose of this study is to compare the clinical results of two operative methods, Bosworth screw procedure and Wolter plate technique.
MATERIALS AND METHODS
We have analysed 30 patients with acromioclavicular dislocations, which had been treated by Bosworth screw & Wolter plate technique from June 1996 to February, 2002 with minimal 1 year follow up. All patients were assessed clinical and radiological results by ASES Score and UCLA Score.
RESULTS
Using the Shoulder evaluation scheme of ASES and UCLA Score at the one year follow up examination, 93.4% of the patients had excellent results in Wolter plate group. In Bosworth screw group, 4 complications such as loosening of the screw, or breakage of screw were seen. 2 complicated patients were over 40 years old and then conversions to Wolter plate operation was needed and obtained good results.
CONCLUSION
Bosworth procedure has a merit not to damage acromioclavicular joint, but the technique is difficult, sometimes may be encountered loss of fixation due to overcorrection and anterior displacement of the clavicle. However, Wolter plate implant provides enough stability for active postoperative physiotheraphy, and hence accelerates rehabilitation. Therefore, this technique is thought to be a good modality in the treatment of acute acromioclavicular seperation.

Abstract PDF: PURPOSE
To evaluate the result of modified Bosworth method augmented with Mersilene tape(MBM) compared with modified Bosworth method(MB).
MATERIALS AND METHODS
Thirty two acromiclavicular dislocation wrer treated with MB(15cares) or MBM(17 cases) and the mean follow up period was 26 months(12-43 months). We assessed the radiological and clinical evaluation(X-Ray & Weitzman Criteria) and complications.
RESULTS
Twenty nine cases(91%)(MB 13, MBM 16) were "excellent" or "good" according to the Weitzman criteria. At last follow-up, mean difference of the coracocalvialar distance between the normal and the injured site were 1.9mm(MB) and 1.6mm(MBM) and two ceses were developed the arthritis, and then performed the distal clavicle resection.
CONCLUSION
Modified Bosworth method augmented with Mersilene tape is a good option for acromioclavicular dislocation in stabilizing the joint, even if the screw loosening occurs with early postoperative ROM.

Modified Phemister Operation for Acromioclavicular Dislocation: Jin Yung Park, Gun Nam Kim, Byung Sam Min, Moon Jib Yoo; J Korean Soc Fract 2001;14(3):456-462. Published online July 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.3.456

Abstract PDF: PURPOSE
To evaluate the clinical results after modified Phemister operation for complete dislocation of acromioclavicular joint.
MATERIALS AND METHODS
Thirty-seven cases of Fifty-three cases complete dislocation of acromioclavicular joint which were treated modified Phemister operation, follow up for at least one year, were evaluated. After operation, applied Kenny-Howard brace for six weeks and removed the inserted pins at ten to twelve weeks postoperatively. The ROM exercise was started at postoperative six weeks and meticulous ROM exercise was begun at pin removal. The clinical results were evaluated with range of movement, comparision of the coracoclavicular distance after surgery with that of follow up, and complications.
RESULTS
The range of motion were forward elevation 150 degree, external rotation 71 degree, external rotation at 90 degree abduction 77 degree, and internal rotation T8. The comparision of coracoclavicular distance after surgery(0,6mm) with that of follow up(1.0mm) showed no significant ligament laxity. The complication were subluxation in 2 cases, heterotrophic calcification in 3cases, broken K-wire in 2cases, pin site infection in 7cases and distal clavicle osteolysis in 3cases, which were healed at follow up radiographically.
CONCLUSION
To prevent of redislocation of acromioclavicular joint, we tried to insert the pin during relatively long period for sufficient healing of ruptured coracoclavicular ligament. Although immobilization period was relatively long period, clinical results were good.

Coracoid Process Fracture Associated with Acromioclayicular Dislocation and Partial Rupture of Coracoclavicular Ligament: A Case Report: Seok Woong Yoon, Tae Sung Hwang, Byung Gue Park, Ki Hoon Kil; J Korean Soc Fract 1999;12(3):693-697. Published online July 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.3.693

Abstract PDF: A coracoid process fracture associated with acromioclavicular dislocation has been reported infrequently. A coracoid process fracture associated with coracoclavicular ligament rupture has been reported only in two cases. Two separated injury mechanisms seem to be involved in this instance; one is direct trauma to the shoulder girdle causing dislocation of acromioclavicular joint, and the other is sudden avulsive pull on coracoid process by the conjoined tendons of short head of biceps brachialis and coracobrachialis, and pectoralis minor muscle causing fracture of the coracoid process. We reported one case of coracoid process fracture associated with acromioclavicular dislocation and partial rupture of coracoclavicular ligament. The lesion was treated by open reduction and interanl fixation using two Kirschner - wires for the acromioclavicular joint and a cortical screw for coracoid process, and the result was satisfactory without complication.

Results Following The Surgical Treatment of Acromioclavicular Joint dislocations; A Comparison of Phemister With Bosworth Operation: Jin young Park, Suk Joo Lyu, Ki Hyuk Moon, Myung Ho Kim; J Korean Soc Fract 1998;11(1):8-15. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.8

Abstract PDF: To compare the results the Bosworth with Phemister operation, we performed the Bosworth operation in 7 case and then Phemister operation in 9 case serially from 1994 to 1997 and followed them up postoperatively. The average follow-up was 19.2 months, with the longest being 32 months, and the shortest being 12 months. The extraarticular coracoclavicular fixation was done with a cancellous screw in Bosworth operation, the transarticular fixation with two or three Kirschner wires in Phemister operation and the coracoclavicular ligaments were sutured to all patient in phemister operation group. The average immobilization period 6.8 weeks(S.D.:1.0 weeks) in Bosworth operation, 6.5 weeks(S.D.:1.4 weeks) in Phemister operation. The cancellous screw or the Kirschner wires were removed in 12.6 weeks(S.D.:1.6 weeks) postoperatively in Bosworth operation, 11.8 weeks(S.D.:1.7 weeks) in Phemister operation and physiotheraphy was progressed to obtain the full range of motion. All of the patients were evaluated on a subjective(pain, night pain, medication. instability, activities of daily living), objective(range of motion) and roentgenographic(degree of displacement) basis at last follow-up. Shoulder function was assessed according to the shoulder score devised by the American Shoulder and Elbow Surgeons. The pain of Shoulder persisted remained in 1 case of Bosworth operation and in 3 cases of Phemister operation. The night pain around acromioclavicular joint was remained in 2 cases of Phemister operation. Average shoulder function index in Bosworth operation was 95 points and in Phemister operation 87 points. Average range of motion of Bosworth operation was 176degree (S.D.:9degree in forward elevation, 68degree(S.D.:11degree in external rotation, 88.6degree(S.D.:12degree in cross-rotation at 90degreeabduction, 22cm (S.D.:11cm) in cross-body adduction and T9 in internal rotation and Phemister operation 147degree(S.D. 18degree in forward elevation, 72degree S.D.:12degree in external body adduction and T8 in internal ratation. All of the patients were satisfied for results of operation. After surgery, loss of reduction was found in 3 of 7 in Bosworth operation and all of the patients were over 40 years and then conversions to Phemister operation was needed. According to short-term follow-up we prefer the transarticular Phemister method and Bosworth operation may be avoided in patients over 40 yeras old.

Surgical Treatment of Acromioclayicular Joint Dislocation with Coracoclavicular Ligament Reconstruction using Coracoacromial Ligament: Seung Rim Park, Hyoung Soo Kim, Joon Soon Kang, Woo Hyung Lee, Joo Hyung Lee, Min Seon Rim; J Korean Soc Fract 1997;10(4):949-955. Published online October 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.4.949

Abstract PDF: Several treatment methods for complete acromioclavicular(AC) joint dislocation have been recommended. This study was performed to evaluate the results of the injuries that had been treated operatively with Bosworth technique combined with coracoclavicular ligament reconstruction using coiacoacromial ligament. Between September 1992 and October 1995, 19 cases were treated with this method. We made an assessment of the results suggested by Taft. Subjectively, fifteen patients had no pain or stiffness. 17 patients had normal strength and full range of motion objectively. On the roentgenographic bases, 16 cases showed normal findings and one showed the subluxation of the AC joint. The overall Taft score was 10.8 points and 84 % of the patients showed good or excellent results. The advantages of this method include anatomical reduction of the AC joint and early motion of shoulder. Ligament reconstruction enables early removal of the lag screw which precludes joint stiffness and metal problems. We conluded that this method was a good surgical method for complete AC joint dislocation.

Treatment with bone block transfer of coracoacromial ligment in acromioclayicular injury: Byung Chang Lee, Sang Soo Kim, Dae Moo Shim, Sang Do Cha; J Korean Soc Fract 1996;9(1):146-153. Published online January 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.1.146

Abstract PDF: Several studies have shown the effectiveness of reconstruction of acromioclavicular ligament with coracoacromial ligament in treating the Grade III acromioclavicular joint injury. One of these is a bone block transfer of coracoacromial ligament into the medullary canal of the clavicle to prevent occasional pullout of the transfered ligament. Eleven cases with complete acromioclavicular dislocation(acute 3, chronic 8) were treated by this method. We modified slightly the original method described by Shoji et at. to increase the success rate. Failure of coracoclavicular reconstruction occurred in two cases. All except one patient regained nearly painlefs range of shoulder motion. One patient showed severe restriction of shoulder abduction and definite deformity. In functional evaluation by the Weitzman criteria, five were excellent, four good, one fair, and one poor. Radiologic results for restoration of coracoclavicular interval showed marked improvement but were not consistent with clinical results. Main technical problems were harvesting bone block and fixation of ligament. To obtain good osseus healing without pull out of transferred ligament, we found that preservation of bone ligament junction and careful harvest of full thickness acromiai bone block was important.

Complication Folloing Operative Treatment in Complete Acromioclavicular Joint Dislocation: Sung Kwan Hwang, Jae In Ahn, Heui Jeon Park, Zi Hoan Cha; J Korean Soc Fract 1988;1(1):64-70. Published online November 30, 1988; DOI: https://doi.org/10.12671/jksf.1988.1.1.64

Abstract PDF: The conservative treatment such as plinting, bandaging and harnessing in the partial disrupton of the acromioclavicular joint(Grade II or less) has been successuful, but many surgeons prefer to operative treaments for complete A-C dislocation(Grade III). Though more than 55 operative methods of treatment were reported in the literature, they could be divided into four categories: 1) acromioclar reduction and acromioclavicular fixation, 2) acromicoclavicular reduction, coracoclavicular ligament repair, and coracoclavicular fixation, 3) distal clavicle excision, and 4) muscle transfers. Among numerous operative methods, we used Weaver-Dunn technic, A-O tension Band technic, and Modified bosworth technic in total 28 cases of complete A-C dislocation from March 1984 to June 1988 at the Yonsei University Wonju College of Medicine, Wonju Christian Hospital. In most cases, excellent or good results were obtained, but we stillfound swveral postperative complications. We experienced neither deep wound infection nor osteomyelitis. All 6 cases had fixation-related complications. After close examination of operation notes and X-rays, following suggestions were considered. 1. Reduce every A-C joint anatomically before inserting K-wires through A-C joints. 2. Start shoulder motion several days after operation to provide enough time form healing of deltoid and trapezius muscles. 3. Surgenous play a major role to prevent commplications such as malposition of fixatives and incomplete A-C joint reduction
