[Current advances in research of semaphorin 3A:a potential target for the treatment of nospecific low back pain].

Nonspecific low back pain is closely associated with afferent nerve ingrowth into degenerated IVDs and increasing the inflammatory response. Members of the class 3 semaphorins signal their response through two prominent receptors; the NRP (Neuropilin-1) and the Plexin A. Sema3A (Semaphorin3A) is primarily known for their role in modulating neuronal survival as well as neurite outgrowth and guidance via regulation of Sema3A-NRP-1-plexinA signal pathway.

Anteroinferior Psoas Technique for Oblique Lateral Lumbar Interbody Fusion.

Oblique lateral lumbar interbody fusion (OLIF) has been extensively used, with satisfactory outcomes for the treatment of degenerative lumbar disease. This article aims to demonstrate a modified lateral approach, also known as the anteroinferior psoas (AIP) technique for OLIF, which is expected to enhance security by operating under direct vision. The core procedures of our technique are as follows.

Although transforaminal lumbar interbody fusion (TLIF) is a widely accepted procedure, major complications such as cage retropulsion (CR) can cause poor clinical outcomes. Endplate injury (EI) was recently identified as a risk factor for CR, present in most levels developing CR. However, most EIs occurred in non-CR levels, and the features of EIs in CR levels remain unknown.

[Current advances on surgical treatment for knee articular cartilage injuries].

Chondral injuries are short of self-healing ability and need to surgical repair after articular cartilage injury. Conventional treatment includes debridement and drainage under arthroscope, micro-fracture, osteochondral autograft transplantation (OATS), mosaiplasty and osteochondral allografts (OCA), autologous chondrocyte implantation (ACI). Debridement and drainage could remove pain factor, and has advantages of simple operation, wide clinical application and early clinical effect.
