Purpose: The purpose of this study was to introduce a new surgical technique and to evaluate the preliminary results after operative treatment with using TightRope$^{(R)}$ for treating acute acromioclavicular joint dislocation. Material and Methods: We studies 10 patients who were followed up for more than 6 months after operative treatment with using an TightRope$^{(R)}$. A longitudinal incision approximately 4cm in length was made from 1cm medial to the acromioclavicular joint to the coracoid process, and then coracocalvicular ligament augmentation using TightRope$^{(R)}$ was done after splitting the deltoid. For postoperative stability, two 1.6 mm Kirschner wires were inserted temporarily across the acromioclavicular joint in all cases. The radiologic results on the serial plain radiographs and the clinical results according to the UCLA score were analyzed. Results: Radiologically, 7 cases showed anatomical reduction, 2 cases showed a slightly loss of reduction and 1 case showed partial loss of reduction. Clinically, 6 cases were excellent, 3 cases were good and 1 case was fair. Conclusion: Coracoclavicular ligament augmentation using TightRope$^{(R)}$ for treating acute acromioclavicular joint dislocation is a minimally invasive, safe procedure that provides satisfactory radiologic and clinical preliminary results. Yet the long-term results have to be analyzed to determine the final results of this procedure.

Purpose: The purpose of this study is to evaluate the radiologic and clinical results of the arthroscopic coracoclavicular fixation of the acute acromioclavicular dislocation using $TightRope^{(R)}$ (Arthrex, Inc, Naples, FL). Materials and Methods: We performed the arthroscopic coracoclavicular fixation using $TightRope^{(R)}$ in twenty patients with the Rockwood type III or V acute acromioclavicular dislocation between February, 2009, and February, 2010. Mean follow-up was 13.4(range 8~22) months. Radiologic results were evaluated by comparing the distances between the clavicle and the coracoid process with those in the contralateral sides using the acromioclavicular stress radiographs. Clinical results were made according to the KSS(Korean Shoulder Scoring System), and the cosmetic satisfaction of the patient was assessed. Results: Radiologically, 18 cases showed excellent, 1 case showed good and 1 case showed fair results. Clinically, KSS was mean 98.5 (range 92~100) points and all cases revealed satisfactory cosmetic results. Because one case complained of skin tenderness and discomfort of palpation, we closed the knot with surrounding muscle & fascia. Then local wound infection occurred, so we treated it by incision and drainage under local anesthesia and antibiotic therapy for 2 weeks. Conclusion: Arthroscopic coracoclavicular fixation using $TightRope^{(R)}$ for treating the Rockwood type III or V acute acromioclavicular dislocation showed satisfactory radiologic and clinical results. It seems to be a good treatment method that has little postoperative complication, provides an early rehabilitation and an excellent cosmetic result, and does not require secondary operation for removal of metal implant.

Purpose: The proper surgical methods for treating acromioclavicular joint dislocation is still controversial. New methods should provide better early motion with sufficient strength. Materials and Methods: We performed arthroscopic stabilization using TightRope$^{(R)}$ (Arthrex, Inc, Naples, FL) in 10 cases of acromioclavicular joint dislocation between April, 2007, and December, 2007, and followup for a minimum of 10 months. We performed radiologic evaluation by comparing the clavicle anteroposterior radiograph with the contralateral one. Clinical evaluation was made for pain, function, and range of joint motion by Imatani's methods. Results: In clinical evaluation, 6 cases were excellent, 3 cases were good, and 1 case was poor. In radiologic evaluation, 9 cases were excellent and 1 case was poor. Redislocation occurred in 1 case. Conclusion: During short-term followup, 9 of 10 patients who underwent arthroscopic stabilization using TightRope$^{(R)}$ had excellent results in Imatini tests and radiologic evaluation, except 1 patient with redislocation.

Purpose: The purpose of this study is to analyze the results of acute acromioclavicular joint dislocation treatment with coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ (Arthrex). Materials and Methods: From October 2009 to March 2011, 30 patients with acute acromioclavicular joint dislocation underwent coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ and were followed up for at least 12 months after surgery. The radiologic results were qualified according to serial plain radiographs, and the clinical results according to University of California - Los Angeles (UCLA) Shoulder Scale, Constant score, and VAS pain score. Results: Using the UCLA scoring system, excellent results were observed in 22 cases (73%), good results in five cases (17%), fair results in two cases (7%), and a poor result in one case (3%). The average Constant score was $92.5{\pm}7.5$. According to radiologic results, anatomical reduction was achieved in 26 cases, and two cases showed a moderate loss of reduction, and two cases showed complete re-dislocation. Clinical results for patients with re-dislocation were unsatisfactory and reoperation was required. Conclusion: Coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ is a good option providing reliable functional results in patients with acute acromioclavicular joint dislocation.

Nine dogs presented to the Veterinary Medical Teaching Hospital of Konkuk University and Woosung Animal Hospital with a history of pelvic limb lameness. On physical examination, 9 dogs all showed a consistent weight bearing lameness and mild muscle atrophy. There was cranial drawer sign with pain in 9 dogs. Mediolateral radiographic projection revealed cranial subluxation of the tibial tuberosity in a tibial compression view. The right and left stifle joints were affected in 7 dogs and 2 dogs respectively. TightRope cranial cruciate ligament (CCL) technique for treatment of CCL deficiency was performed. Polyester and nylon were used to stabilize the stifle in 3 dogs and 6 dogs respectively. Suture sizes were 0.8 mm (n = 2), 0.9 mm (n = 4), 1.1 mm (n = 2), and $1.1mm{\times}2$ strands (n = 1) in diameter. Mean (${\pm}SD$) surgical duration was $48.3{\pm}8.5$ minutes (range 35 to 60 minutes). Preoperative and postoperative mean (${\pm}SD$) cranial drawer signs were $8.6{\pm}1.6$ mm (rage 7 to 12 mm) and $1.2{\pm}1.0$ mm (rage 0 to 3 mm) respectively. Immediate postoperative radiographs of the affected limb revealed no evidence of cranial subluxation of the tibial tuberosity in a tibial compression view of 9 dogs. Normal limb function was regained in 8 dogs within 8 weeks postoperatively. A consistent weight bearing lameness resolved in all dogs after TightRope CCL technique, but reoccurred in one dog (case No. 6) 2 weeks after surgery. Cranial subluxation of the tibial tuberosity was identified in a tibial compression test. During the second surgery, breakage of surgical button was identified and a tibial wedge osteotomy was performed. Based on surgical time, complication, stifle stability, and functional recovery, the present study indicated that TightRope CCL technique is effective treatment for the dogs with CCL deficiency.

A Korean water deer was rescued with non-weight-bearing lameness of the right hind limb. Clinical and radiographic examination revealed a craniodorsal coxofemoral luxation. The cause of the right coxofemoral luxation (CL) was unknown. We performed minimally invasive arthroscopic-assisted reduction with toggle pin fixation (mini TightRope$^{(R)}$). Craniodorsal CL in the water deer was reduced and stabilized successfully. At 60 days after admission, the water deer was successfully released back into the wild. This minimally invasive surgical technique can be used to correct coxofemoral luxation in wild animals.

Purpose: The purpose of this study was to evaluate the radiologic and clinical outcomes after operative treatment using endobuttons for unstable distal clavicle fractures. Materials and Methods: Between October 2007 and September 2009, 9 consecutive patients who were followed up for at least more than 12 months after operative treatment using a TightRope$^{(R)}$ were studied. The radiologic results on the serial plain radiographs and the clinical results according to the American Shoulder Elbow Surgeons (ASES) score were analyzed. Result: Bony union was shown in 8 cases (88.9%) and the average time to union was 12.9 (range: 9~16) weeks. The average coracoclavicular distances at the postoperative and final follow-up were 5.6 mm and 6.2 mm, respectively, with no statistically significant difference (p>0.05). The average ASES score was 90.3 (range: 78~96) and the clinical outcomes were 6 excellent, 2 good and one fair. There were no complications such as implant failure or infection except for one case of nonunion due to loss of the initial reduction. Conclusion: A major advantage of TightRope$^{(R)}$ fixation for unstable distal clavicle fractures is that no further surgery is needed to remove the implant. We suggest that this technique provides an alternative for fracture with a distal fragment, which is difficult to fix.

The purpose of this study was to explore relationships between family of origin and youth transitioning from out-of-home care. Data were collected from six youths transitioning from out-of-home care and were analyzed using the phenomenological approach. The results of this study were as follows. Four categories and twelve subcategories were drawn from the meaning units. The four categories were 'chaos in separation', 're-established relations but with distance', 'completely ended relationships with the family of origin', and 'redrawing family boundaries'. First, the participants who were separated from their parents due to poverty or divorce reunited with their parents, and they appeared to continue their relationships with the family of origin after transitioning from out-of-home care. The youth were receiving various forms of support from their parents in order to be independent, and they were experiencing stable independence through this support. Second, the participants who were separated from their parents due to serious child abuse or parental death had broken relationships with their parents. The youth were independent and relied on new alternative relationships that were not with the family of origin, but they experienced somewhat unstable self-reliance. In short, participants' relationships with families of origin in this study can be defined as a tight rope between love and hate. Based on these results, child welfare practice and policy implications were discussed to help out-of-home care youth's relationship with their family of origin.
