What is the probability of bone growth 10 mnth post L3-S1 fusion after removal of growth stimulator&complete non-union at L3L4 with 2 loose screws L3?

Ans: First you must why is there no bone growth in a 30 yo? Are you a heavy smoker ? You need a bone density test. You need to eat better and do some passive exercise. There is calcium you can and should take. Better get going or you will have more problems as you age ...Read more

Vertebra (Definition)

Any of the bones that make up the vertebral column. Each vertebra contains an arched, hollow section through which the spinal cord passes. In humans, the vertebrae are divided into cervical, thoracic, and lumbar sections, and the sacrum and coccyx are both made up of a series of fused vertebrae. The vertebrae are separated ...Read more

Bony structure under medial malleolus bilaterally, no pain w/ compression, tibial nerve is palpable, mild flat foot.Could it be misaligned calcaneus?

Misaligned talus: Is usually what happens with what you are describing. This happens in a pronatory foot. Orthotics are good conservative treatment. An implant between the talus and calcaneus is a surgical option. ...Read more

Do granules of a dental bone graft move around? Like under your interior jaw bone near the extraction site.

Do granules of a dental bone graft move around? Like under your interior jaw bone near the extraction site.

Hopefully minimal: One of the reason why the bone graft fail is the instability or movement of the graft. True grafting required graft stabilization with membrane, cages (titanium fixture to protect graft), or screw in the case of block graft. Micromovement of graft will hinder the fibroblast migration and adhesion and interupt vascular genesis. Must achieve good clotting and full closure for graft stabilization. ...Read more

Post. disc herniation w/ assoc. annular tear,completely effaces ventral thecal & produces mass effect upon cord, Max AP 7 mm mod. foramen encroc@ C4-5?

Spine Specialist: By definition you have spinal stenosis in the neck due to the disc herniation. If it is causing problems, see a spine specialist to discuss your options. Epidural steroid injections may relieve the pain, but the disc will take time to heal. If its getting worse or your are noticing weakness see a surgeon to discuss your options. ...Read more

Mri- c5-6 there is apparent central bony bar abutting the ventral cervical cord. What does this mean?

Mri- c5-6 there is apparent central bony bar abutting the ventral cervical cord. What does this mean?

May mean nothing : The bar is a bone spur. Caused by disc degeneration at that level. It is a common finding and may not mean anything clinically. The important question is whether or not there is actual spinal cord compression. Per your question, it sounds as if the spinal canal is narrowed a bit (stenosis), but there is not any spinal cord compression. Frequently, pt and traction can be of benefit. ...Read more

What does this mean? L-5 s-1 there is central disc protrusion which contacts the thecal sac and bilateral facet degenerative change thickening flavum

What does this mean? L-5 s-1 there is central disc protrusion which contacts the thecal sac and bilateral facet degenerative change thickening flavum

Disc & Facet Issues: Looks like by the verbage you gave, your MRI suggests that you have disc herniation at L5/S1. "Central" just means in the middle of the spinal canal,"bilateral facet degenerative change thickening flavum" suggests arthritis of the facet joint and the ligament that protects the spine is thickened due to that arthritis. Protrusion is just another name for a herniation. ...Read more

37 week pregnant.Cervical length is normal. Found loose cord around neck at time of scan. Placenta is anterior in uterus. Maturity grade 1. Suggest?

Normal findings: All of the findings you list are normal. I would continue expectant management and plan on a normal vaginal delivery. A cord around the neck is a common finding and usually doesn't create a problem during labor. (I'm assuming the baby's head is down) Best wishes! ...Read more

All solid zirconium that support span of 4 unit bridge covering teeth 11 to 14 broke after 10 weeks. Previous porc bridge also broken. Causes/options?

All solid zirconium that support span of 4 unit bridge covering teeth 11 to 14 broke after 10 weeks. Previous porc bridge also broken. Causes/options?

Dynamic forces: Many factors can lead to this, but most important are the support base and the bite. This is a long span to cover when starting with the canine, but do not expect the zirconium to fx. Likely clenching/grinding without occlusal guard/compliance . See the expert in reconstruction - Prosthodontist. Consider 2 crowns and 2 implants (12,13) with crowns and bite correction (lower arch). good luck. ...Read more

X-ray results showed- advanced L5-S1 degenerative disc disease, moderate facet in lower lumbar spine, L5-S1 4mm retrolistnesis and moderate sclerosis ?

X-ray results showed- advanced L5-S1 degenerative disc disease, moderate facet in lower lumbar spine, L5-S1 4mm retrolistnesis and moderate sclerosis ?

Worn down: L5-S1 is the lowest motion segment in the spine. The MRI shows that level has become "worn down" leading to degeneration of the disc and the facet joints, sclerosis, and a slight slippage (retro listless) of one vertebrae on the other. Don't hesitate to be seen. Many good treatment options available. ...Read more

2Tarlov cysts at S2 (racepinephrine) 17X15mm and 14X13mm causing scalloping of bone. Feel head and ear pressure. Need surgical removal? Any other treatment methods?

Tarlov cysts: Hello, these are benign perineural cysts or cysts in between the coverings of the nerves, usually found co-incidentally at MRI of low back. Yours are 1.7cm and 1.5cm and are small by comparison. These should not be symptomatic, let alone need surgery, your head and ear pain probably unrelated. But see an expert ~ a neuro-surgeon to ask ! thanks ...Read more

What supports the vertebrae after a microdiscectomy?

What supports the vertebrae after a microdiscectomy?

Microdiscectomy: During a micro discectomy only a very small portion of the disc is removed. The outer portion of the disc known as the annulus remains almost completely intact. There are also joints, ligaments, and muscles around the spine which help to support it. ...Read more

How does articular cartilage differ in appearance from spongy bone?

How does articular cartilage differ in appearance from spongy bone?

Lots: For the most part (with exceptions) articulate cartilage is found at the terminal end of a bone with intent to articulate with the other bone also having articular cartilage. Cartilage is cartilage and bone is bone. Articular cartilages lie over some spongy bone and bone gets more dense further down. The cartilage helps to protect the bone, lubricates, absorbs impact. ...Read more

Will the endodontist lower price? Charged 1700 on top of dentist's 1500 for crown

Will the endodontist lower price? Charged 1700 on top of dentist's 1500 for crown

Ask questions: It is always wise to discuss the fees prior to starting treatment. Fees are often regional, but are largely determined by either 1) the maximum allowed fee based on contractual agreement with an insurance company or 2) whatever the dentist decides is fair. Root canal therapy fees vary widely. Some endodontists will spend more time on a case and charge more (good), some less time and charge more. ...Read more

Local back pain from lifting weights. X-rays lumbar/pelvis/SI joint. Mild Ensteophyte formation at illiac crests. is this common? follow up needed?

Osteophytes are spurs: Osteophytes are bone spurs and accumulate with life and uncertain how much they are contributing to you back pain which can occur for lots of reasons - bone, disc, muscle, tendon, bursa etc. I suspect you had the osteophytes way before you were lifting weights. You need an evaluation for the reason you have back pain. ...Read more
