A posterior subluxation of L5 on S1 means that the lowest lumbar vertebra has translate posterior and is likely inferior relative to the spinous. In other words the lowest bone before your sacrum is has slipped backwards and the little bump, such as those you feel when you run your fingers over someone's vertebrae, is pointing slightly downward. A subluxation invloves a very, very small amount of displacement. Sometimes as little as a fraction of a millimeter.

What causes an Posterior annular tear of L5-S1?
A posterior annular tear is a tear in the ligament fibers that cover the inner core of a disc. The discs separate each vertebra in your spine. A posterior annular tear in the L5-S1 discs indicates the location in which these tears occur. L5 is the fifth and lowest of the lumbar vertebra and the S1 is the first and highest sacral vertebra.

What is posterior disc herniation of the L5 S1 impinging on the anterior aspect of the spinal cord?
Posterior means "rear" - Anterior means "front. What the report is saying is that the L5/S1 disk is herniated at the back of the disk (posterior) and is impinging on the front of the spinal cord as a result. This is very common for that particular disk, as well as the L4/5 disk.

Moderate to severe degenerative loss of disc height at the lumbosacral junction with mild degenerative type posterior subluxation and associated broad-based annular disc bulge which is subligamentous?
Fairly rare MRI term associated with spondylolisthesis at the L5/S1 level... The disk is dragged forward by the spinal slippage and on MRI appears to be herniated (which it isn't)...
