Two-photon intravital imaging of thrombus development.

Thrombus development in mouse mesenteric vessels following laser-induced injury was monitored by high-resolution, near-real-time, two-photon, intravital microscopy. In addition to the use of fluorescently tagged fibrin(ogen) and platelets, plasma was labeled with fluorescently tagged dextran. Because blood cells exclude the dextran in the single plane, blood cells appear as black silhouettes.

Subscapularis lengthening in shoulder arthroplasty.

Purpose: To report the technique and outcome of subscapularis (SSC) lengthening in shoulder arthroplasty.

Procedure: When external rotation measures less than 20 degrees, a coronal subscapularis lengthening is performed. This utilizes the interval between the anterior shoulder capsule and subscapularis to titrate the correct amount of anatomic length.
