Cyclic and Load-to-Failure Properties of All-Suture Anchors in Human Cadaveric Shoulder Glenoid Bone.

Purpose: To evaluate the cyclic displacement and ultimate load to failure of 4 all-suture anchors in human cadaveric shoulder glenoid bone.

Methods: Four all-suture anchors indicated for glenoid labral repair were tested in 14 matched pairs of human cadaveric fresh-frozen glenoids. Anchors were inserted at 4 different locations for a total of 112 tests (12-, 3-, 6-, and 9-o'clock positions for right glenoids).

Greater Tuberosity Decortication Decreases Load to Failure of All-Suture Anchor Constructs in Rotator Cuff Repair.

Purpose: To evaluate the effect of greater tuberosity decortication on ultimate load to failure and displacement after cyclic loading with an all-suture anchor.

Methods: A 2.9-mm all-suture anchor was evaluated in decorticated and nondecorticated greater tuberosities of 10 matched pairs of human cadaveric shoulders.

Slight Reduction in the Insertion Depth for an All-Suture Anchor Decreases Cyclic Displacement in the Shoulder Glenoid.

Purpose: To determine if the depth of anchor insertion affects the biomechanical performance of a 1.5-mm all-suture anchor in glenoid bone.

Methods: A 1.

The effect of biceps adhesions on glenohumeral range of motion: a cadaveric study.

Background: Previous studies have demonstrated that the humerus slides along the long head of the biceps tendon (LHBT). Blocking this motion may result in decreased glenohumeral (GH) range of motion (ROM). The goal of the study was to characterize the excursion of the LHBT and measure the effect of biceps adhesions on GH ROM.

Polycomb group protein ezh2 controls actin polymerization and cell signaling.

Polycomb group protein Ezh2, one of the key regulators of development in organisms from flies to mice, exerts its epigenetic function through regulation of histone methylation. Here, we report the existence of the cytosolic Ezh2-containing methyltransferase complex and tie the function of this complex to regulation of actin polymerization in various cell types. Genetic evidence supports the essential role of cytosolic Ezh2 in actin polymerization-dependent processes such as antigen receptor signaling in T cells and PDGF-induced dorsal circular ruffle formation in fibroblasts.
