Background: There is no standardized therapeutic strategy for locked posterior shoulder fracture-dislocation (PSFD), and no consensus exists on the analysis of preoperative factors. This retrospective study aimed to evaluate functional results and complications in a series of PSFD cases managed with open surgical treatment. Methods: Patients diagnosed with locked PSFD who underwent open surgical treatment with reduction and osteosynthesis between April 2016 and March 2020 were included. All participants were treated with open reduction and internal fixation. Functional assessment used the modified University of California, Los Angeles (UCLA) mod scale, American Shoulder and Elbow Surgeons (ASES) questionnaire, subjective shoulder value (SSV), and visual analog scale (VAS). Complications were evaluated clinically and radiologically by X-ray and computed tomography. Results: Twelve shoulders were included (11 patients; mean age, 40.6 years; range, 19- 62 years). The mean follow-up duration was 23.3 months (range, 12-63 months). The UCLA mod, ASES, SSV, and VAS scores were 29.1±3.7, 81.6±13.5, 78±14.8, and 1.2±1.4 points, respectively. The overall complication rate was 16.6%, with one case of post-traumatic stiffness, 1 case of chronic pain, and no cases of avascular necrosis. Conclusions: Open surgical treatment of locked PSFD can achieve good functional results. A correct understanding of these injuries and good preoperative planning helped us to achieve a low rate of complications.

Purpose: Traumatic posterior dislocation of the shoulder in a child is extremely rare, and posterior dislocation of the shoulder concomitant with ipsilateral humeral surgical neck fracture has not been reported in a child previously in Korea. Materials and Methods: The authors treated a 10-year-old with posterior dislocation of left shoulder and an ipsilateral humeral surgical neck fracture, that occurred during Taekwondo practice, by open reduction of the shoulder and pin fixation under general anesthesia. Results: A normal range of motion with complete union and good remodeling was achieved without redislocation or avascular necrosis of humeral head at 1 year after surgery. Conclusion: The authors report a successfully treated case of traumatic posterior dislocation of the shoulder with an ipsilateral humeral surgical neck fracture in child.

The aims of this retrospective study were to evaluate the results of inferior capsular shift operation which were approached anteriorly or posteriorly according to a main instability direction in contact sports population who had multidirectional shoulder instability. Fifty-three shoulders in 47 athletes who engaged in contact sports underwent an anterior or posterior inferior capsular shift procedure for the correction of multidirectional instability of the shoulder joint. The surgical approach was selected according to the predominant direction of the instability. Follow up was average of 42 months(24∼73 months). After anterior inferior capsular shift, anterior dislocation was recurred in three shoulders, posterior dislocation in one, and inferior dislocation in two shoulders. After posterior inferior capsular shift, one dislocation occurred anteriorly, one inferiorly and one posteriorly. The excessive tightening of capsule or improper diagnosis could be causative factors for the development of dislocation in the opposite direction to the preoperative major instability. Of six patients who could not return to their sports, five had bilateral repairs. Successful repair based on the criteria of the American shoulder and elbow association was achieved in 92% of anterior repairs, and 81 % of posterior repairs.

Sternoclavicular joint posterior dislocations are considered a very uncommon, and type of injury where if esophagus or airway injury occurs behind the clavicle, it poses a high risk to the patient. In addition, if epiphyseal fracture occurs as a result of the sternoclavicular joint posterior dislocation, surgical treatment is often required. However, in the absence of a complete ossification of the clavicle, it is difficult to differentiate between a simple dislocation and epiphyseal fracture-dislocation solely based on simple radiographs or computed tomography scans. In this case report, the authors present a case in which a sternoclavicular joint posterior dislocation was diagnosed in a 14-year-old male athlete. The case report discusses how the posterior dislocation without epiphyseal fracture was diagnosed using an ultrasound and subsequently treated with successful outcomes using manual reduction. The case report presents our findings along with discussion that includes a literature review of relevant research.

A posterior shoulder dislocation with a fracture is rare. Most fractures are impression fractures of the humeral head or lesser tuberosity fractures. However, there are no reports of a complete rupture of the rotator cuff with a combined posterior glenohumeral dislocation. We report a unique case of a posterior shoulder dislocation with an avulsion fracture of the greater tuberosity and a complete rupture of infraspinatus, teres minor and subscapularis tendons, which were treated surgically.

Pure anterior bilateral shoulder dislocations are rare clinical features, especially in traumatic forms. They are most often posterior, occurring during an epileptic seizure. Few cases are described in the literature, and the mechanism varies from case to case. We report a specific case of pure bilateral anterior shoulder dislocation in a 29-year-old judo player following an accident during his training and discuss the circumstances, mechanism, treatment, and prognosis.

Purpose: Bilateral traumatic locked posterior dislocations of the shoulder are very rare and there has been no report on the operative treatment for this injury in the Korean medical literature. Materials and Methods: We present here a case of bilateral locked posterior dislocations of the shoulders after trauma and this was successfully treated with open reduction and lesser tuberosity transfer on the right shoulder and subscapularis tendon transfer on the left shoulder. Results and Conclusion: Twenty-four months later, the clinical and radiologic results were excellent.

Purpose: This study evaluated clinical results, and recommended treatment protocol of traumatic anterior shoulder dislocation in the patients older than 60 years of age. Materials and Methods: Thirty-eight patients with first traumatic anterior shoulder dislocation aged over 60 years were included. The average age was 69.4 (range, 60 to 87 years). There were 8 men (average age of 71.6) and 30 women (average age of 69). Most common cause of injuries was a fall on the outstretched hand. The additional injuries were evaluated using MRI or CT arthrogram in the patients with significant pain and weakness while movements after 2 weeks sling immobilization. Results: Fifteen patients (39%) had rotator cuff tears and 5 patients (14%) had greater tuberosity fractures. The sizes of rotator cuff tears were diverse; 2 partial tears, 1 small tear, 4 medium tears, 3 large tears and 5 massive tears. Among 5 massive cuff tears, 3 patients revealed cuff arthropathy after reduction. 4 patients (11%) had recurrent dislocation more than one time during 1 month after the first dislocation. Bankart lesions revealed in 5 patients and three of them had associated rotator cuff tears. 3 out of 5 patients with Bankart lesions, 13 out of 15 patients with rotator cuff tears and 3 patients with displaced greater tuberosity fracture had operations. Conclusion: The injury mechanism of shoulder dislocation in patients older than 60 years of age seems to have either anterior or posterior mechanism. The diagnosis and treatment should be approached 2 weeks after dislocation.

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.

Clavicular hook plate is known to be an effective treatment on acromioclavicular (AC) joint injury, but there have been some reports of complications, like osteolysis and bony erosion of the undersurface of acromion. Fifty-five year old male underwent open reduction and hook plate insertion on Rockwood type 5 acromioclavicular joint dislocation. He complained of protrusion of posterior acromion at 1 month after the surgery, and acromial fracture was noted in simple radiographs. The hook plate was removed and any other treatment for osteosynthesis was refused by the patient. At the 18 months after the surgery, the patient had no pain and a full range of motion with no tenderness around the shoulder joint. After two years, plain radiographs revealed complete bony union of the acromion fracture.
