Chronic temporomandibular joint dislocation is defined as an acute dislocation that cannot be reduced or that recurs for more than one month. The management of dislocation depends on patient status and the duration of dislocation and ranges from conservative reduction to a surgical approach. In the present cases, a 64-year-old male was referred to our department for treatment of chronic dislocation for 6 weeks. The dislocation might be occurred by endotracheal intubation. A 70-year-old female was referred to our department with repeat right condyle dislocation after reduction of dislocation at a local clinic. When she visited for later treatment of new dentures, her condyle had been dislocated again for several weeks. In both cases, we tried to treat the dislocation with several manipulations, which were unsuccessful. Finally, chronic dislocation was successfully treated by surgical traction under general anesthesia without relapse. Surgical traction is a simple, effective option with the lowest morbidity of surgical procedures for chronic dislocation when conservative reduction is unsuccessful.

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.

Purpose: Acute traumatic peroneal tendon dislocation is relatively rare disease and their methods of treatment is controversial, that we want to assess the characters and outcomes of 8 patients with early surgical treatments. Materials and Methods: We evaluated the results of 8 patients who can follow up more than 28 months using sex, age, side, injury sports, concomitant injuries, Eckert and Davis classifications, anatomic variants, results and complications. Results: All of 8 patients was male, average age was 27, Right side was dominant (5/8), causal sports was variable. Concomitant injuries were distal tibiofibular ligament syndesmosis injury, Peroneus longus injury, lateral collateral ligament injury. On behalf of Eckert and Davis classifications 5 patients were Grade 1 and other 3 patients were Grade 2. 1 case of low lying peroneus brevis belly was found as an anatomic variants. 6 of patients shown excellent results, 2 patients were good. Post operative complications were discomfort of operation site and mild limited dorsiflexion on ankle joint. Conclusion: Careful history and physical exam is important for diagnosis. And surgical treatments can expect good results.

Purpose: We wanted to evaluate the clinical outcomes after operative treatment using two suture anchors and Kirschner wire for treating acute Rockwood type V acromioclavicular joint dislocation Materials and Methods: Between May 2006 and May 2009, 10 patients underwent surgical treatment for acute Rockwood type V acromioclavicular joint dislocation using two suture anchors and Kirschner wire and they were followed for a mean of 12.0 (range: 7-31) months. We analyzed the functional results by the Korean shoulder score, the Constant-Murley score and the reduction state of the acromioclavicular joint at the last follow-up. Results: All the cases achieved a satisfactory outcome. The mean Korean shoulder score was 89.9 (range: 81-100) points and the mean Constant-Murley score was 87.8 (range: 82-93) points. According to the radiologic findings, 8 patients achieved anatomical reduction of the acromioclavicular joint: there was a slight loss of reduction in one patient and a partial loss of reduction in one patient. None of the patients had deep infection or re-dislocation. Conclusion: The operative treatment using two suture anchors and Kirschner wire may be used for acute Rockwood type V acromioclavicular joint dislocation, and it has an advantage in that it can prevent chondral injury of the joint.

Temporomandibular joint dislocation causes considerable pain, discomfort, and swelling. The anatomic construction of the articular fossa and the eminentia articularis may predispose to dislocation, and weakness of the connective tissue forming the capsule is believed to be a predisposing factor. The capsule may be stretched and, more rarely, torn. Dislocation may be unilateral or bilateral and may occur spontaneously after stretching of the mouth to its extreme open position, such as during a yawn or during a routine dental operation. Manual reduction with the patient under muscle-relaxing condition or anesthesia is recommended method. After the reduction of an acute dislocation, immobilization of the jaw is recommended to allow the stretched and sometimes torn capsule to heal, thus preventing recurrence. A Barton's bandage may be applied for 2 to 3 weeks to prevent the patient from opening the jaw too wide. But, it results in recurrent dislocation in the neurologically disabled patient, because of loose intermaxillary fixation. This is a case report about management of recurrent temporomandibular joint dislocation by multiple loop wirings and intermaxillary elastics in cerebrovascular accident patient.

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.

Traumatic anterior dislocation of the shoulder is one of the most common directions of instability following a traumatic event. Although the incidence of shoulder dislocation is similar between young and elderly patients, most studies have traditionally focused on young patients due to relatively high rates of recurrent dislocations in this population. However, shoulder dislocations in older patients also require careful evaluation and treatment selection because they can lead to persistent pain and disability due to rotator cuff tears and nerve injuries. This article provides an overview of the nature and pathology of acute primary anterior shoulder dislocation, widely accepted management modalities, and differences in treatment for young and elderly patients.

Medial dislocation of the long head of the biceps brachii is a rare condition that usually occurs in association with tears of the subscapularis, chronic impingement, capsular defects or a fracture of the lesser tuberosity. Less commonly, a biceps tendon dislocation may occur after an acute traumatic event. Following a dislocation, the biceps tendon will assume either an intra- or extra-articular position depending on whether or not the subscapularis tendon detaches from its humeral insertion. Magnetic resonance imaging has been found to provide valuable information concerning the location of the biceps tendon and the integrity of the subscapularis tendon. We present a patient with a traumatic dislocation of the biceps brachii tendon in which the diagnosis remained elusive for an extended period of time. In this case, he was evaluated using MRI and reconstruction was performed by restoring the tendon to its anatomical position.

Background: The purpose of this study was to evaluate the clinical outcomes and complications of hook plate fixation in acromioclavicular (AC) joint dislocations and distal clavicle fractures. Methods: We retrospectively reviewed a series of 60 consecutive patients with hook plate fixation for AC joint dislocation (group I) and distal clavicle fracture (group II). Groups I and II had 39 and 21 patients, respectively. Clinical results were evaluated using the pain visual analogue scale (VAS), simple shoulder test, and Constant-Murley scores. In addition, subacromial erosion and stiffness were evaluated as complications. Results: At the removal, the pain VAS was $2.69{\pm}1.30$ and $4.10{\pm}2.14$ in groups I and II, respectively, which were significantly different (p=0.003). The simple shoulder test score was $9.59{\pm}1.60$ and $7.81{\pm}2.67$ in groups I and II, respectively, which were also significantly different (p=0.002). Subacromial erosion was significantly more frequent in group II (14/21 patients, 66.7%) than in group I (15/39 patients, 38.5%) (p=0.037), and stiffness was also higher in group II (17/21 patients, 81.0%) than in group I (22/39 patients, 56.4%), but it was not significant. Conclusions: Hook plate fixation showed good clinical and functional results for the treatment of acute unstable AC joint dislocation and distal clavicle fracture. But, in distal clavicle fractures, there are more subacromial erosion and stiffness compare with acute unstable AC joint dislocation.
