Abstract Percutaneous vertebroplasty PV and kyphoplasty PK are the 2 vertebral augmentation procedures that have emerged as minimally invasive surgical options to treat painful vertebral compression fractures VCF during the last 2 decades. VCF may either be osteoporotic or tumor-associated. Two hundred million women are affected by osteoporosis globally.

How is the interbody fusion surgery carried out? This is the reason why anterolisthesis refers to the condition of the spine in which the upper body of vertebral, the area shaped like drum at the front of each vertebrae slips forwards on to the vertebra.

Peer Reviewed Journal Medical material team The team researches and develops bone graft, a material used for endodontic treatment and orthopedic treatment.

The magnitude of slippage is graded by doctors in to scales from one to 1 to 4. To get exactly what this term means it is also very good to understand the meaning of the term vertebra.

The vertebra singular or vertebrae plural are those bones that form an opening in which the human spinal cord passes through. The vertebrae are positioned on top of one another like stacks. At the front part of each vertebra is a thick part of bone that is shaped like a drum and which is referred to as vertebral body.

Between every two vertebrae there are disks which are referred to as the intervertebral discs. The discs look like cushions and they are flat in shape. The main purpose of the intervertebral discs is that they absorb and protect the spinal cord and the vertebrae from shock.

In anterolisthesis, there is abnormal positioning of the upper vertebral body when compared to the body of the lower vertebra. As stated above, the upper vertebral body tends to slip in forward direction to the vertebra below it.

Causes of Anterolisthesis Anterolisthesis is mainly caused by great impact on the spinal cord anterolisthesis cervical spine or spondylosis or the vertebra mainly the c4 and c5 anterolisthesis c4 c5.

It could be due to falls from high heights, bullet wounds, impact from vehicle collisions, injury from sporting activities, and such related events. In severe cases, the anterolisthesis is accompanied by the fracture of other bones that are adjacent to the spinal cord.

All these events will gradually lead to degenerative anterolisthesis changes or mechanical breakdown of the segment. Spinal column and its different regions Source: To avoid this condition, the persons at risk especially the older members of the society are advised to engage in exercises for anterolistheis and to maintain good body posture when sleeping, sitting and in other daily activities.

Symptoms of Anterolisthesis The symptoms as of anterolisthesis may vary greatly because the intensity and severity of the same is dependent on the amount pinch that the slippage exerts on the nerve roots.

The symptoms may also vary depending on the area that is affected by the slippage. That pain may be localized or wide spread. The pain will keep on worsening because of the muscular spasms or guarding as the body attempts to protect itself.

The muscle spasms and guarding will cause them to tighten and this will cause inflammation and severe pains around the tissues that are adjacent to the disc, spine and nerve roots.

The pain receptors will thus generate more and severe pain thus creating endless vicious cycle of increasing pain. The pain may be experienced at one or both legs of the patient.

Some patients also complain of weakness of the legs and this may or may not be accompanied by numbness. In anterolisthesis, weakness of the muscles indicates that the condition may cause serious damage of the body nerves and it should be addressed as soon as possible.

Although prostate cancer is the most common male cancer in B.C. (with the exception of non-melanocytic skin cancer), relatively little is known concerning its etiology. formulated into acrylate-based bone cement; current bone cements are synthesized from methyl methacrylate (MMA) and employ inorganic additives for sufficient contrast, thereby weakening the mechanical properties of the material. throughout the material and debonding of the material at the cement-bone interface (8). Cement particles as a result of fracture can induce osteolysis at the bone-cement interface, further loosening the implant and ultimately resulting in failure (6). Bone cement failure can also occur from porosity.

Other anterolisthesis symptoms include: Inability to control the legs Abnormal sensations Inability to control the passage of urine or bowel movements If you had an injury, fall, or you were involved in an accident and you start experiencing the already mentioned symptoms then there is high possibility that you might be suffering from anterolisthesis.

What should you do if you suspect that you have Anterolisthesis? Anterolisthesis is serious condition that may have debilitating consequences if proper medical intervention is not sought as soon as possible.

If you think that you may have developed anterolisthesis you should act quickly. You can suspect to be having this condition if you experience lumbar spine instability or severe pain of the spine that does not subside after three days.the effect of thickness and pressure on the curing of pmma bone cement for the total hip replacement by guy m.

connelly a thesis presented to the graduate committee. Bone cement is used in orthopaedic surgery to replace or bind bone fragments resulting from trauma, to fill cavities, or to secure an implanted prosthesis. Any enduring bone cement must be biocompatible, be stable in the physiological environment, and have adequate mechanical properties for stresses applied during daily activity.

IN SHORT: Syringomyelia (SM) is an extremely serious condition in which fluid-filled cavities develop within the spinal cord near the brain.

It is also known as "neck scratcher's disease", because one of its common signs is scratching in the air near the neck. This thesis examines changes in strains within the cement mantle and bone surrounding distal ulnar implants, as a function of cement-stem interface bonding.

A method to embed strain gauges within the cement mantle of the restrictive distal. Thank you for the valuable information about ANTEROLISTHESIS. I was walking along a cement curb/wall the suddenly fell about 8 inches so that I stepped off into thin air, fell hard landing on the concrete with the base of my spine ‘tailbone’.
