We evaluated 31 painful shoulders of 30 patients with chronic arthritis by ultrasonography (US) and compared the results with those of magnetic resonance imaging (MRI). Both US and MRI revealed effusion in the subacromial-subdeltoid (SA-SD) bursa, biceps tendon sheath (BTS) and glenohumeral (GH) joint, but MRI was more accurate in depicting joint inflammation because of its ability to visualize...

The surgical technique for repair of acute proximal hamstring tears is relatively recent. Installation of the patient is critical. The approach is either vertical under the gluteal fold in case of a complete tear with tendon retraction of more than 6 cm, or horizontal in the gluteal fold for retraction of less than 6 cm or for partial tears. After identification and neurolysis of the sciatic ne...

We propose a partial solution to the cosmological constant problem by using the simple observation that a three-brane in a six-dimensional bulk is flat. A model is presented in which Standard Model vacuum energy is always absorbed by the transverse space. The latter is a tear-drop like space with a conical singularity, which preserves bulk supersymmetry and gives rise to conventional macroscopi...

Introduction: The clinical outcomes of rotator cuff repair vary among patients and are affected by multiple factors including chronic inflammation. Although inflamed synovium is a common clinical observation at the time of surgery, the role of this inflammation plays on clinical outcomes is not well elucidated. Several recent studies have shown that there is elevation of pro-inflammatory cytoki...
