TL;DR: It is demonstrated that the new cortical trajectory and screw design have equivalent pullout and toggle characteristics compared with the traditional trajectory pedicle screw, thus confirming preliminary clinical evidence.

TL;DR: The 3Dprinted porous titanium interbody cage resulted in statistically significant reductions in ROM, increases in the bone ingrowth profile, as well as average construct stiffness compared with PEEK and PSP.

TL;DR: It is demonstrated that an interpositional graft consisting of rhPDGF-BB (75 or 150 μg) and a type I collagen matrix was able to improve the biomechanical strength and anatomic appearance in an ovine model of rotator cuff repair compared to a suture-only control and the 500-μg rhPD GF-BB group.

TL;DR: It is demonstrated that repair of a chronic tendon tear with the polyurethane scaffold mesh provides greater mechanical strength in the critical healing period than that of traditional suture anchor repair.

TL;DR: Evidence is provided that the cortical screw trajectory represents a good option to obtain fixation for the lumbar spine with low-quality bone and provides denser bone that allows for utilization of smaller screws to obtain mechanical purchase that is equivalent to long pedicle screws placed in traditional pedicle screw trajectories for both normal- and low- quality bone.
