The authors analyzed the extent of proximal junctional (PJ) motion and intradiscal pressure changes in a cadaveric model of long-segment thoracolumbar pedicle screw–only fixation versus hybrid constructs involving supplemental Mersilene tape or single-level or 2-level sublaminar band insertion. The study identified sublaminar banding as a comparatively effective surgical technique that can mitigate PJ stresses and thereby expand the transition zone between the rigid instrumented and mobile non-instrumented levels in long-segment thoracolumbar constructs.

Transpsoas lateral lumbar interbody fusion (LLIF) is a common spinal procedure, which may be performed using a standalone cage or a cage with posterior instrumentation. The authors compared surgical outcomes between these two techniques and found that standalone LLIF may be associated with higher rates of subsidence and reoperations. These results will aid surgeons in preoperative discussions with patients set to undergo this procedure. Moreover, further biomechanical research is warranted for making a stable cage design for the standalone approach.

In this experimental study, the authors evaluated the anatomical feasibility of different nerve transfers to provide new nerve supply to the lower limb as well as the outcomes of nerve transfer for restoration of function in an animal model of spinal cord injury. In the future, such transfers might help patients with spinal cord injuries to regain control of some movements, possibly enabling them to stand independently or even step forward with assistive devices.
