Background: Based on different treatment outcomes and different treatment methods for acromioclavicular dislocation, we decided to evaluate the treatment outcomes of acromioclavicular joint dislocation using tightrope arthroscopy.

Methods: This retrospective cross-sectional study was performed on patients with acromioclavicular joint dislocation referred to Alzahra Hospital in Isfahan and Abadan-Iran from 2015 to 2017. Information that was assessed included age, sex, type of dislocation (Figure 1), duration of injury, cause of injury, complications such as osteoarthritis, changes in the distance between the joints, as well as the American Shoulder and Elbow Surgeons Shoulder Score (ASES) were collected after 6 months of surgery.

Backgroud: Changes in perianchor cysts around the all-suture anchors, which demonstrate distinguished features from the biocomposite anchors, have not been revealed sufficiently. The purpose of this study was to investigate serial changes of perianchor cysts according to the location of the inserted anchor in the glenoid in arthroscopic labral repair using all-suture anchors.

USC Epstein Family Center for Sports Medicine, Keck Medicine of USC, Los Angeles, CA, USA.

Backgroud: Recent literature suggests that three-dimensional magnetic resonance imaging (3D MRI) can replace 3D computed tomography (3D CT) when evaluating glenoid bone loss in patients with shoulder instability. We aimed to examine if 2D MRI in conjunction with a validated predictive formula for assessment of glenoid height is equivalent to the gold standard 3D CT scans for patients with recurrent glenohumeral instability.

Methods: Patients with recurrent shoulder instability and available imaging were retrospectively reviewed. Read More

Department of Orthopaedic Surgery, Kitasato University School of Medicine, Sagamihara, Japan.

Background: Rotator cuff tears (RCTs) are often associated with severe shoulder pain. Non-steroidal anti-inflammatory drugs, not recommended for long-term use, do not effectively manage RCT-induced pain, resulting in reduced quality of life. To improve management, a better understanding of the fundamental properties of RCT pain is needed. Read More

Background: Acute sternoclavicular fracture-dislocation is associated with high-energy trauma and is being increasingly recognized in children. These injuries are associated with compression of mediastinal structures and can be life-threatening. The management of acute sternoclavicular fracture-dislocation includes closed reduction or open surgical stabilization; however, limited success is reported with closed reduction. Read More

Introduction: Shoulder trauma with normal radiographs is a frequent emergency presentation. The predominance of pain makes clinical examination unreliable, and complementary imaging is often needed for diagnosis. The aim of the present study was to assess the contribution of ultrasonography (US) and magnetic resonance imaging (MRI) in deciphering such trauma. Read More

The surgical treatment of recurrent anterior shoulder dislocation is a difficult problem in the field of sports injury medicine. The main reason focus on dynamic and osseous constraints of shoulder joint could not recover well. At present, arthroscopic surgery is used at home and abroad, and could receive statisfied postoperative effect, but the choice of specific surgical methods is still controversial. Read More

Peachtree Orthopaedics, Atlanta, GA, USA. Electronic address:

Background: Glenoid labrum tears are a common cause of shoulder pain and instability and tear patterns have historically been ascribed into categorical descriptions such as anterior, posterior, and superior labral tears (SLAP) with multiple sub-types. Although often quoted as representing no more than 10% of instabilities, posterior shoulder instability may be more common than previously recognized. The purpose of this study was to review observed labral tear patterns and compare incidence and morphologies to historical descriptions. Read More

PLoS One 2021 21;16(5):e0251880. Epub 2021 May 21.

Department of Mechanical Engineering, Imperial College London, London, United Kingdom.

Objective: To develop and assess a novel guidance technique and instrumentation system for minimally invasive short-stemmed total shoulder arthroplasty that will help to reduce the complications associated with traditional open replacement such as poor muscle healing and neurovascular injury. We have answered key questions about the developed system including (1) can novel patient-specific guides be accurately registered and used within a minimally invasive environment?; (2) can accuracy similar to traditional techniques be achieved?

Methods: A novel intra-articular patient-specific guide was developed for use with a new minimally invasive posterior surgical approach that guides bone preparation without requiring muscle resection or joint dislocation. Additionally, a novel set of instruments were developed to enable bone preparation within the minimally invasive environment. Read More

Background: Limited evidence is available regarding the recommended technique of revision surgery for recurrent shoulder instability. Only 1 previous study has compared the results of soft tissue repair and the Latarjet technique in patients with persistent shoulder instability after primary surgical stabilization.

Case: An 11-month-old boy was brought to the emergency department because he was refusing to use his right arm. X-rays demonstrated an anteroinferior Salter-Harris I fracture-dislocation of the proximal humeral epiphysis. Closed reduction with sedation was unsuccessful, so open reduction under general anesthesia was pursued. Read More

BACKGROUND Early failure of osteosyntheses is common even with use of locking plates. In patients with comminuted fractures and epiphyseal osseous defects, we performed a series of osteosyntheses by locking plate in combination with an allograft bone augmentation. Because of encouraging short-term results in the literature, we assumed that the method could be a potential alternative to a reverse shoulder prosthesis. Read More

Clinical Scenario: Pathologies of the long head of the biceps brachii (LHB) tendon are a source of shoulder pain in many people. It is important to have a reliable assessment of the LHB tendon to make an accurate diagnosis and provide the correct treatment or referral if necessary. Shoulder ultrasound is very accurate in the diagnosis of rotator cuff tears. Read More
