Missed Medial Clavicular Physeal Fracture-Posterior Dislocation Complicated by Brachiocephalic Pseudoaneurysm: A Case Report.

Case: We present a 17-year-old male patient with an initially missed posterior sternoclavicular fracture dislocation who presented with symptoms related to thrombotic emboli arising from a pseudoaneurysm. He was treated 6 weeks after injury with a figure-of-eight tendon allograft repair with good clinical outcomes.

Conclusion: This is a unique presentation that highlights the significant risk of a missed diagnosis, life-threatening complications that may ensue, and biomechanically superior surgical intervention.

Acquired Acromion Compromise, Including Thinning and Fragmentation, Is Not Associated With Poor Outcomes After Reverse Shoulder Arthroplasty.

Background: Acquired acromial compromise, including thinning (less than 30% of the normal acromion) or fragmentation resulting from acromiohumeral impingement or previous acromioplasty, is a concern in reverse shoulder arthroplasty (RSA). This condition may lead to shoulder pain and difficulties in arm elevation because of acromial insufficiency fracture.

Questions/purposes: (1) Do patients with acromial compromise (thinning less than 30% of normal acromion or fragmentation) have worse functional outcome scores, ROM, and strength after RSA compared with patients without acromial compromise? (2) Are patients with acromial compromise at a higher risk of complications such as acromial insufficiency fracture after RSA? (3) Do patients who develop acromial insufficiency fracture have predisposing associated factors and worse clinical outcomes?

Methods: Between January 1, 2016, and December 31, 2020, we treated 398 patients with RSA, and all patients were considered potentially eligible for this study.

Stress fracture of the clavicle associated with sternocostoclavicular hyperostosis combined with bony ankylosis of the acromioclavicular joint and ossification of the coracoclavicular ligament.

Sternocostoclavicular hyperostosis (SCCH) has been reported in patients with pustulotic arthro-osteitis, but there are few reports of marked ossification of the lateral part of the clavicle. Here, we report a case of stress fracture in a patient with SCCH with marked ossification of the lateral part of the clavicle. In this case, the clavicular fracture was proximal and no dislocation.

Quality and stability of reduction of operated acromioclavicular dislocation using dual acromioclavicular and coracoclavicular stabilization.

Introduction: Dual stabilization is advocated in acute acromioclavicular dislocation (ACD), but has been little assessed.

Objective: This preliminary study performed clinical and radiological assessment of dual acromioclavicular (AC) and coracoclavicular (CC) stabilization in acute ACD. The study hypothesis was that dual stabilization allows satisfactory reduction that remains stable over time.

Traumatic posterior sternoclavicular joint dislocation - Current aspects of management.

The posterior sternoclavicular joint dislocation is a rare and potentially life-threatening injury, as massive haemorrhage can occur at the time of trauma, during reduction manoeuvres and drilling. These injuries are rare and a collective experience of managing them is of paramount importance. We present our multidisciplinary experience of managing several of these injuries in our centre, with learning points we have identified.

Aortic arch impingement with Salter Harris II epiphyseal fracture of the medial clavicle: A novel use of video assisted thoracoscopy.

Posterior dislocation of the sternoclavicular joint (SCJ), although uncommon, can be life-threatening. Displacement of the clavicular head poses a threat to the vital structures of the mediastinum. We describe the case of a 15-year-old boy with traumatic Salter Harris II medial clavicular fracture with posterior dislocation of the metaphysis resulting in impingement of the aortic arch, left subclavian and common carotid artery, as well as partial obstruction of the brachiocephalic vein.

Simultaneous acromioclavicular dislocation, proximal humeral fracture, and reverse Hill-Sachs lesion: a case report.

Background: In cases with injuries to the shoulder region, the combination of acromioclavicular joint dislocation, reverse Hill-Sachs lesion, and proximal humeral fracture is a very rare condition.

Case Presentation: This study described a 38-year-old male Persian patient with simultaneous acromioclavicular joint dislocation, proximal humeral fracture, and reverse Hill-Sachs lesion due to motor vehicle crash injury who underwent arthroscopic acromioclavicular joint fixation using tight rope technique. In the 7-month follow-up period following the surgical fixation, range of motion was approximately normal.

Sonographic Fracture Diagnosis in Children and Adolescents.

Background: Clinical examination after trauma, especially in young children, often proves difficult. As a result, the majority of images show unremarkable findings in the imaging workup of trauma by radiography. Sonography represents an imaging technique without the use of X-rays.

Current Concepts in Sternoclavicular Joint Injuries.

Therapeutic Level V. See Instructions for Authors for a complete description of levels of evidence.

Complications after operative treatment of high-grade acromioclavicular injuries.

Background: Treatment of Rockwood type III-V acromioclavicular (AC) joint injuries remains controversial. Numerous reconstruction techniques have been proposed. The purpose of this study was to describe the complication profile in a large cohort of patients who underwent surgical management of AC joint separations using a variety of reconstruction strategies.
