Return to play after rotator cuff tear in National Football League athletes.

Background: Rotator cuff tears are rare injuries in National Football League (NFL) athletes and there are limited data to help guide players and team physicians. The purpose of this study was to assess return to play (RTP) rates, performance levels, and career length following a rotator cuff tear during their playing career.

Methods: Using publicly available data, we identified players who sustained a rotator cuff tear between 2000 and 2019.

Cross-elements to enhance fixation in osteoporotic bone with application to proximal humeral locking plates: a biomechanical study.

Background: Proximal humeral fractures occur predominantly in elderly, osteoporotic individuals, especially women, with surgery performed in one-fifth. Proximal humeral locking plates are the gold standard operative treatment; however, complications are frequent, partially because of poor screw purchase in osteoporotic bone. A new method uses threaded posts through which threaded cross-elements orthogonally pass to create a 3-dimensional scaffold for bone engagement.
