Enterferential current: It is used to increase circulation and reduce pain. In the lumbar disc herniation, the method of vacuum application with 4 electrodes is frequently used due to its greater efect. The treatment period is usually 20-30 minutes. Diadinamic current: It is applied more in acute period pain.

The commonest imaging finding in myelopathy is either focal or diffuse cord hyperintensity on the T2-weighted magnetic resonance (MR) images (T2 WI). Intramedullary T2 hyperintensity can pose a serious dilemma in spinal imaging because it has a myriad of causes, which can be difficult to differentiate.

The inter-lamellar matrix (ILM) lies between the lamellae of the annulus fibrosus (AF) of the inter- vertebral disc and has a thickness of less than 30mm. The ILM is comprised of four main components: Matrix, cross-bridges, elastic fibers, and cells; how- ever, those components are not restricted to the ILM alone (i.e., cross-bridges are ...

The annulus fibrosus (AF), which constitutes the outer part of the IVD, plays a key role in the mechanical and biological integrity of the IVD. Closure and repair of ruptured AF in herniated discs is yet an unmet clinical need. As a standard surgical treatment for disc herniation, discectomy leaves the ruptured AF as it is in case of limited ...
