The lumbosacral joint connects L5-S1
Lumbarization of the s 1, or top segment of the sacrum, refers to a birth defect where the sacrum is not fused to the rest of the spine properly. Experts believe it is simply something that happens inside the womb, and very rarely affects a person's health.
Your spinal cord is made up of 5 different areas, based on how many vertebrae (pieces of spine) make it up. You have: 7 CERVICAL 12 THORACIC 5 LUMBAR 5 SACRAL 5 COCCYGEAL Therefore the lumbosacral junction (where lumbar meets sacral) is assumed to be at L5 (the 5th and last lumbar vertebrae) and S1 (the 1st sacral vertebrae).
The S1 nerve is the first sacral nerve. It leaves the the spine via a foramen in the top fused bone of the Sacrum. The sacrum forms the posterior part of the Pelvis and this is where the Root nerve S1 can be found before it quickly joints the lumbosacral plexus.
The sacrum bone in the posterior pelvis comes from the fusing of 5 sacral vertebrae, which are numbered from superior (S1) to anterior (S5). The sacral bones fully fuse typically by around age 23, but sometimes the S1 vertebra does not fus with the others. When this happens, it's called lumbarization.
the spinal nerves which comprise the brachial plexus are C5 - C8 and T1. lumosacral plexus are L1 - L5, S1 - S4 and SR.

no it is not, a lumbosacral sprain is the severe stretching, while a lumbosacral strain is a partial or complete tearing
Acute left lumbosacral paravertebral myofascitis ICD-9 code is 724.2
The lumbosacral junction is located in the lower center of the back and between the hips. It consists of the L5 vertebral and the first sacral vertebral body.
Lumbarization (US) lumbarisation (UK) refers to a spinal bone that takes on some of the appearances and physical characteristics of another type of vertebrae or spinal bone. At S1 lumbarisation means the S1 segment, which is usually, one of five fused segments making up the sacrum or tail bone, is not fully fused or attached to the rest of the tail bone. IT is a "sacral" segment that looks like a "lumbar" segment. It appears to be 6th lumbar vertebrae. It may have a disc or a rudimentary disc space. Functionally, a lumbarized S1 usually does not have all the functions of a normal lumbar vertebra. In most instances, this finding is interesting, but does not usually cause pain or disability. In some rare cases the joint may become irritated and painful due to injury.
