I’m genuinely impressed with the Ultrassist Human Lumbar Spine Model model! It’s not only well-designed and well-crafted, but it also has a sturdy quality. It fits in well in the OT office we use it. The level of detail is fantastic, and you can really point out the details of the back’s mechanics. Nice model. The only negative is that the stand doesn't feel as well made as the model.

The material of the product is pretty good with good size! I wish it's a little bit harder material but it's overall well made and good accuracy of the lumbar spine and sacrum.

I own a lot of odd things and this blended in perfectly. It’s a little over a foot tall. Love how it is see through. The hole in the bottom that sits on the stand isn’t deep enough so we just drilled further. Overall cool item.

I think this would make a great item to display in a dr's office or school etc.. very solid, detailed, and expandable to view the inner workings/tendons/ligaments etc.. that make our backs work like they do!

This item is a clear plastic human spine, which appears to be made of vertebrae from T 11 through L5 and includes the sacrum and coccyx. T 11 through L5, and the L5-S1 segment are articulated with a spring which is visible through the clear plastic material. White plastic intravertebral disc’s are also present and articulated through the spring as well. This model does exhibit range of motion flexion and extension. It is very limited and rotation. Sacrum and coccyx are molded from one solid piece of plastic. There is a yellow plastic spinal cord traveling through the. Vertebral foramen with branching nerve roots and ganglia exiting through the intervertebral foramina at each segment, and these are appropriately labeled T12, L1, etc. There are some accuracy issues with the inserted plastic spinal cord as it appears to indicate that the cauda equina begins at L5-S1. The conus medullaris should be occurring in the adult at L1 to L2 level.Overall, this is a decently constructed, pretty model, and reasonably accurate for display or limited office instruction for a patient. However, the lack of any demonstrated pathologic changes, such as ruptured discs or retrolisthesis limits its use in this capacity. It could be useful for learning some of the basic vertebral anatomy however, for the price, more accurate models can be purchased.If you’re looking for something to look cool on your desk or possibly to make it to an award, this would work just fine. If you want to purchase a serious teaching aid, perhaps consider something different.

The whole thing is assembled on a strong coil spring giving it excellent rigidity while also allowing for movement. The vertebra are crystal clear, the discs are functional like real discs and the spinal cord is pliable. The base holds it steady and the whole model is easily taken off and put back for up close examination. It is very impressive and I even noticed how a vertebra can be moved out of position slightly and then can be slid back into place so they sit correctly again. I think it offers a great value for anyone who might need a visual aid about the spinal cord or wants to give an extremely nice gift to someone in the medical field.

The actual spinal column itself is really very well done. Clear vertebrae, nice (but basic) representation of the cord and nerves, realistic discs, and realistic movement. The only letdown is the display base itself. It's not particularly robust. It works, but it could be better at this price point.Overall a very nice scale, lifelike representation of a spinal column (but somewhat basic).

As a display piece, it has a couple shortcomings that are, frankly, unacceptable at the $100 price point: 1) The pedestal is a nice, heavy chunk of what I assume is painted wood. It has the weight to offer good stability, but it wasn't cut particularly square and wouldn't look great on display. 2) The hole at the bottom of the spinal acrylic wasn't drilled wide enough to accept the base's peg, and probably not deep enough at only 5/16". Nor was it even drilled round. It looks like someone was in too much of a rush and melted the acrylic, caving in the hole. That or it was a formed hole and that process wasn't carried out nearly as well as the rest of the piece.That said, the realism and visual feedback are impressive. The lady of the house says it's destined to be an adult toy if I don't get the base fixed...UPDATE: A 1/4" drill bit looked like the right size to match the base's post, so I expanded the partial hole in the acrylic, following its path as straight as possible. I drilled the existing hole probably an inch deeper (what anyone was thinking in drilling it so shallow is beyond me), and now have a stable display. However, following the existing hole revealed another flaw in the execution: it wasn't even drilled straight to start with. The whole thing sits at an angle now.
