Background & Aims: Acute acromioclavicular (AC) joint dislocation is common in shoulder injuries. Considering the biomechanics of this joint, the use of a treatment method, which can restore joint physiology and biomechanics to the extent possible, is important. This study aimed to compare the treatment of acute AC joint dislocation by screw fixation with and without ligament reconstruction. Me...

Acromioclavicular (AC) joint injuries are common and often seen in contact athletes, resulting from a fall on the shouldertip with adducted arm. This joint is stabilized by both static and dynamic structures including the coracoclavicular (CC)ligament. Most reconstruction techniques focus on CC ligament augmentation as the primary stabilizer of the AC joint.The best surgical technique for some ...

Background: Reconstructions of acute acromioclavicular (AC) dislocations have been thought to result in superioroutcomes than chronic dislocations. The use of tendon graft in reconstructions has demonstrated favorablebiomechanical properties. To determine whether utilizing tendon graft during repair of acute AC dislocations results insuperior outcomes and lower complication ra...

BACKGROUND Several different surgical techniques have been described to address the coracoclavicular (CC) ligaments in acromioclavicular (AC) joint injuries. However, very few techniques focus on reconstructing the AC ligaments, despite its importance in providing stability. The purpose of our study was to compare the biomechanical properties of two free-tissue graft techniques that reconstruct...

INTRODUCTION Techniques for reconstruction of the dislocated acromioclavicular (AC) joint are numerous. Most, however, do not incorporate reconstruction of the disrupted acromioclavicular ligaments and capsule. Evidence exists supporting the importance of these ligaments particularly in providing horizontal stability to the AC joint. Recently, biomechanical studies have demonstrated improved AC...

Introduction: Quantitative evaluation is recommended to improve diagnostic ability and serial assessment of dopamine transporter (DAT) density scans. We decided to compare the ordered subsets expectation-maximization (OSEM) with filtered back-projection (FBP), and to investigate the impact of different iteration and cut-off frequencies on SBR values.

INTRODUCTION Surgical treatment of chronic complete acromioclavicular (AC) joint dislocation is still debated and no gold standard surgical procedure has been identified. MATERIALS AND METHODS A retrospective series of 90 patients treated for AC dislocations is reported here. Patients were divided into three groups: group 1 receiving AC reconstruction with a Dacron vascular prosthesis; group ...
