We report two cases of migration of K-wires from the acromioclavicular joint to the neck. A 73-year-old man complained of right shoulder pain for one month and had undergone orthopedic surgery because of acromioclavicular joint dislocation about 27 years earlier. Another 56-year-old man complained of left shoulder pain and neck pain for 5 years and had undergone orthopedic surgery because of acromioclavicular joint dislocation about 25 years earlier. In both cases, we took X-rays to look for the cause of shoulder pain and discovered broken and migrated K-wires in the neck. We removed the K-wires from the trapezius muscle and the paraspinal muscle respectively. K-wire fixation technique is simple and effective but should be followed up with X-rays periodically. In addition, we should warn patients of the possibility of migration of K-wire. And it is desirable for us to avoid using K-wire near major neurovascular structures like the sternoclavicular joint and the clavicle.

Synovial chondromatosis is a rare disease. The knee is the most commonly affected joint but the shoulder joint is very rarely affected. We report typical synovial chondromatosis of the shoulder joint which was managed by arthroscopic removal of multiple loose bodies, synovectomy, good objective and functional outcome was obtained until postoperative 7-year follow-up. Arthroscopy can be used as an effective and useful therapeutic method for synovial chondromatosis of the shoulder joint.

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.

Neuropathic shoulder arthropathy or Charcot's shoulder is an extremely rare disease, and sometimes it is associated with cervical syringomyelia. Clinical symptoms of the disease include edema of the shoulder and restriction in range of motion. Radiological diagnosis can be made through plain radiography through a characteristic, atrophic destruction of the joint. We experienced a Charcot's joint of the shoulder wherein destruction of the joint progressed extremely quickly and reviewed the literature concerning this condition.

Background: To compare the treatment of the proximal humerus fracture using a Polarus nail or Philos plate, we aimed to analyze the functional recovery and the factors affecting the selection between the two types of surgery. Methods: The study included 107 patients with proximal humerus fracture who underwent surgery at our institution. Of these patients, 67 underwent surgery with Polarus nails (G1) and 40 with Philos plates (G2). In G1, the cases of two- and three-part fractures were 60 and 7 cases, in G2, the cases of two-, three-, and four-part fractures were 28, 10, and 2 cases, respectively. The average age was 61 years old, and the average follow-up period was 32.5 months. We compared radiological results, the functional recovery retrospectively. Results: The radiological union time was 6.8 weeks and 8.7 weeks on average in G1 and G2 (p < 0.05). At the one-year follow-up period, these were visual analogue scale (VAS) 1.355, forward flexion (FF) 130.968, external rotation (ER) 50.161, internal rotation (IR) L2 in G1, and VAS 0.781, FF 135.806 ER 51.25, IR L1 in G2, respectively, showing no significant differences between the two groups (p > 0.05). Similar observations were made at the final follow-up. In terms of functional recovery, no significant differences were seen at the one-year or at the final follow-up period (p > 0.05). Conclusions: For the surgical treatment of proximal humeral fracture, the selection of the type of surgery is affected by the fracture pattern. However, both methods give satisfactory outcomes and do not show significant differences in the functional outcome after the surgery.

Repair of the rotator cuff tear is a joint-tightening procedure that can worsen joint stiffness. This paradoxical phenomenon complicates treatment of rotator cuff tear with joint stiffness. As a result, there is controversy about how and when to treat joint stiffness. As many treatments have been published, this review discusses the latest findings on treatment of rotator cuff tear with joint stiffness.

Calcific tendinitis of the shoulder joint, also known as chemical furuncle of the shoulder, causes intense shoulder pain and usually occurs within 1-2 cm from the insertion of the rotator cuff. We experienced a rare case of calcific tendinitis in the posterosuperior labrum of the shoulder joint in a 39-year-old male patient who presented with severe pain and weakness in the right shoulder. Radiographs and magnetic resonance imaging (MRI) findings showed calcific tendinitis in the posterosuperior labrum of the shoulder joint. A 1-week attempt at conservative treatment failed, so the calcified deposit in the posterosuperior labrum was arthroscopically removed. The patient's symptoms were completely relieved, and satisfactory clinical outcomes were achieved. Postoperative follow-up X-ray and MRI showed no recurrence of calcific tendinitis.

Eponymization serves as a means of paying tribute to individuals who have made significant contributions to our culture. Each eponym is often linked with a story for everyone to discover. To aid in the retention of these stories, this review offers readers an overview of the individuals behind the eponymous terms, as well as their original descriptions, within the context of acromioclavicular joint pathology and orthopaedic surgery.

Calcific tendinitis is the leading cause of shoulder pain. Among patients with calcific tendinitis, 2.7%-20% are asymptomatic, and 35%-45% of patients whose calcific deposits are inadvertently discovered develop shoulder pain. If symptoms are present, complications such as decreased range of motion of the shoulder joint should be minimized while managing pain. Patients with acute calcific tendinitis respond well to conservative treatment and rarely require surgery. In contrast, patients with chronic calcific tendinitis often do not respond to conservative treatment and do require surgery. Clinical improvement takes time, even after surgical treatment. This review article summarizes the processes related to the diagnosis and treatment of calcific tendinitis with the aim of helping clinicians choose appropriate treatment options for their patients.

Rheumatoid arthritis (RA) is a systemic disease with medication as the treatment of choice. However, surgical treatment is recommended when no improvement is noted despite aggressive conservative treatment. Synovectomy provides desirable outcomes for RA patients in the early stage with a glenohumeral joint of Larsen grade II or less; conversely, arthroplasty is recommended for patients with a glenohumeral joint of grade III or higher. RA patients often have attenuation and dysfunction of the rotator cuff, and reverse shoulder arthroplasty has been proven to provide favorable outcomes in some patients. RA is often complicated with osteoporosis and bony deformity; therefore, close attention is necessary to prevent fractures during shoulder arthroplasty.
