Dr. Usman Zahir MD's Expert Contributions
There a wide variety of causes for leg pain while walking, it depends where the location is: 1.) Is the pain just around a specific area of the leg, like the knee? (That would mean more of a joint problem) 2.) Does the pain start in the lower back and then travels down the leg? (More of a nerve problem) 3.) Did you have a recent fall or injury? With a bit more information, most causes are easier to figure out. READ MORE
During a laminectomy we are increasing the space for nerves by removing a part of the spine called a lamina. During a laminectomy we take care not to damage the facet joints. The facet joints are on each side of the spine and they play a very important role in keeping our spines stable. As surgeons we also do our best to preserve muscles and ligaments that support the spine. Today, laminectomies can be performed with less invasive methods - this helps minimize the risk of instability (slips in the spine). When the facet joints are damaged or wear out there is a greater chance of causing the spine to weaken and become unstable overtime...this can result in back pain, leg pain, and/or weakness READ MORE
