Operative intervention is recommended for complete acromioclavicular (AC) joint dislocation to restore AC stability, but the best operative technique is still controversial. Twelve fresh-frozen male cadaveric shoulders (average age, 62.8 7.8 years) were equally divided into endobutton versus the modified Weaver-Dunn groups. Each potted scapula and clavicle was fixed in a custom made jig to allo...

BACKGROUND Ulnar collateral ligament reconstruction is commonly performed in major league pitchers, but little is known about pitching performance after a return to major league play. HYPOTHESIS Pitching performance after ulnar collateral ligament reconstruction returns to baseline by the second season after surgery. STUDY DESIGN Cohort study (prognosis); Level of evidence, 2. METHODS Dat...

BACKGROUND Numerous surgical techniques have been described to address injuries to the coracoclavicular ligaments. PURPOSE To compare the biomechanical properties of tendon graft reconstructions with those of the native coracoclavicular ligaments and various other repair methods. STUDY DESIGN Controlled laboratory study. METHODS Eleven fresh-frozen human cadaveric shoulders were tensile t...

In the present study the stiffness of the superficial ligaments of 14 human cadaver wrist joints have been determined. In these experiments the tested, fresh-frozen carpal joints are divided into a number of bone-ligament-bone complexes, which are loaded in a tensile testing machine at a rate of 66% of the ligaments' initial length per second to a maximal strain of 15%. From the force-elongatio...

To explore the effect of occlusal adjustment in mandibular second molar with different distal alveolar bone losses on stress distribution periodontal ligament, a left was modelled using finite element analysis based X-ray CBCT scanned images and effects. The equivalent ligament analyzed to study biomechanical properties molars areas losses. Results demonstrate that tissue plays an important rol...

INTRODUCTION The aim of our study was to compare US, conventional MRI and MR arthrography findings in patients with anterior shoulder instability and with a clinical diagnosis of labral capsular ligamentous complex lesion. At the same time we evaluated the accuracy of MR arthrography in the diagnosis of this lesion. METHODS After approval of the local Ethics Committee, our department's Trauma...

Traumatic injury of the aorta, inferior vena cava, and iliac vessels due to penetration of the anterior anulus fibrosus and anterior longitudinal ligament is a recognized complication of lumbar disc surgery. The authors report, to the best of their knowledge, the first case of discectomy-related superior rectal artery injury treated by endovascular intervention.

We present a case of suprascapular nerve idiopathic total palsy lasting for 2 years, with intraoperative finding of suprascapular nerve partial section by the superior transverse scapular ligament. This highlights the importance of early surgical management with an open procedure for suprascapular neuropathy of unknown etiology.
