Artificial Bone Replacement
Are there total knee replacement options, besides traditional artificial joint replacement surgery?
Yes: Alternatives to total knee replacement include partial knee repalcement and osteotomy. Partial knee replacement is done if the arthritis is confined to only one part of the knee. Osteotomy is done if there is an angular deformity contributing to overloading of one side of the joint. ...Read moreSee 5 more doctor answers
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
Have scientists found total knee replacement options, other than traditional artificial joint replacement surgery?
Yes: Depending on the nature of the condition, there are several options. Cartilage repair surgery continues to develop for early knee damage. For more significant involvement of 1 side or compartment of the knee, a partial knee replacement may relieve pain and restore function. If the knee has severe damage, a total knee replacement is indicated. ...Read moreSee 2 more doctor answers

Progressive: For cervical, encourage ambulation day one, with progress towards longer walks, getting the heart rate up. Simultaneously, passive range of motion of the neck, increasing as tolerated, with return to low impact upper extremity weights, bands after two weeks, increased as tolerated, keeping total weight to a level where the surgical site is isolated and effort is smooth, and easy. ...Read moreSee 1 more doctor answer
Yes: Most knee replacements are made of cobalt alloys because they are harder. The titanium is generally too soft to work as a knee surface. There is, however, one total knee replacement made of titanium where they have hardened the end of the titanium (making it a ceramic compound). ...Read moreSee 1 more doctor answer
Like a fusion: Similar to a disk fusion, access to the spine is from the front. The disk is removed, the vertebrae are prepared and the disk replacement is placed in between the two vertebrae. Find a neurosurgeon or ortho spine surgeon who does many of these to achieve maximal success. ...Read moreSee 2 more doctor answers
Depends: The answer depends on the anatomy of the problem and of course the symptoms present. Many people have degenerative discs and live pain free. Fusions can be done if there is instability or deformity present. Disc replacement can be done in the absence of instability and deformity if the patients pain correlates well with the imaging findings. See a spine surgeon to discuss further. ...Read more
Need specialist: There are several locations and surgeons who perform many disk replacements and can answer your questions about who can get a disk replacement. Fda regulations specify age 18-59. There cannot be much instability in the segment being considered for disk replacement. Make sure you investigate the place where you're considering having it done- preferably a place that participated in the studies. ...Read moreSee 1 more doctor answer
Are there any other total knee replacement options, other than traditional artificial joint replacement surgery?
Several choices: Depending on the wear status of the knee, unicompartmental replacement may be an option. Osteotomy (realignment) of the leg may also be an option. As for total knee replacements, there are custom cutting guides, custom implants, and computer navigation options, but none have been shown to be superior to traditional tka performed by an experienced surgeon. ...Read moreSee 2 more doctor answers
Pain relief: Joints are typically replaced when they become arthritic and painful. Artificial joints do not function as well as normal joints, but do perform better than painful/arthritic joints. Range of motion and strenght are typically improved with joint replacement surgery, which leads to better function. Artificial joints will all eventually wear out and there are some limitations with there use. ...Read more

An X-Stop is : Indicated for treatment of lumbar spinal stenosis at one or two levels but not usually at l5-s1 as there is usually not proper available anatomy to secure its placement there. Artificial disc is indicated for treatment of back pain without presence of severe degeneration or spinal stenosis or any instability at that spinal segment. They are used for different diagnoses so not interchangeable. ...Read more
No: X-stop, achieves decompression by elevating the two dorsal processes, into a slightly bent forward position, which simulates bending forward on a shopping cart to reduce symptoms of spinal stenosis. An artificial disc actually replaces a damaged disc and provides more normal intervertebral biomechanics and does not, ideally alter sagittal balance. ...Read more
Uncommon: Infection after tha is a known complication that occurs in 0.1-2% of hip replacement procedures. Factors that can affect this incidence include patient conditions such as obesity, diabetes, or immune system diseases, as well as the length of surgery time, wound closure methods, and experience of the surgeon. Some hospitals and surgeons have higher rates of infection. ...Read moreSee 2 more doctor answers
It depends: It depends on many things. What is the age of the patient? Is there pre-existing arthritis? What is the type of fracture? Most of the time, if you can preserve the normal bone and cartilage it is better than metal and plastic. For elderly, they already have arthritis or the bone is too soft for screws, etc. So the best option is a replacement. ...Read moreSee 1 more doctor answer
No such thing: You either have a cow bone (allograft) or synthetic bone. Cow bone usually is harder, and actually are very good bone graft material (they are more expensive than human cadaver bone and synthetic bone). Their bone structure is similar, but more dense than our bone. Upon resorption, they would be replaced by much denser bone fill. All grafting material resorp and replaced by our real bone. ...Read moreSee 2 more doctor answers
