💡 MRI vs CT Scan vs X-ray?

➡️ MRIs use magnetic fields and radio waves (no radiation) to create highly detailed 3D images of soft tissues like muscles, ligaments, and the brain.

• How it works: Uses powerful magnets and radio waves to create detailed 3D images of soft tissues and organs without using radiation.

• Best for: Examining soft tissues like muscles, tendons, ligaments, and the brain; good for spinal injuries, tumors, and nerve issues.

• Limitations: More time-consuming, can be noisy, and may not be suitable for people with certain metal implants (like pacemakers).

➡️ CT scans use radiation to create detailed 3D images, often used for emergencies, complex fractures, and organs.

• How it works: A series of X-rays are taken from multiple angles and combined by a computer to create cross-sectional, 3D images.

• Best for: Detailed views of bones, internal organs, and soft tissues; often used for trauma and emergencies due to its speed.

• Limitations: Uses more radiation than a standard X-ray.

➡️ X-rays use radiation to create 2D images, primarily for bones and dense structures.

• How it works: Uses a small amount of radiation to create a 2D image.

• Best for: Detecting fractures, dislocations, and other issues in bones.

• Limitations: Poor at showing soft tissue details.

12/03/2025

Did You Know: The path your pain travels can indicate which lumbar nerve is irritated, a condition known as lumbar radiculopathy or sciatica, with different nerves affecting different areas. For example, pain radiating down the back of the thigh and into the calf and heel is often associated with an L5 or S1 nerve root, while an L4 nerve root might cause pain that moves more into the front of the thigh and shin.

How nerve location relates to pain:

• L4 Nerve Root: Irritation here can cause pain, numbness, or weakness that travels down the front of the thigh and shin. You may experience weakness when trying to lift your foot (dorsiflexion).

• L5 Nerve Root: This often causes pain that travels from the lower back and buttocks down to the outer thigh, the front or side of the lower leg, and the top of the foot. Weakness in the ability to lift your foot (dorsiflexion) is common.

• S1 Nerve Root: This is a common cause of pain that radiates down the back of the thigh, into the calf, and to the heel and outer side of the foot. Weakness is present when rising onto your tiptoes, and the Achilles reflex may be lost.

When to seek immediate medical attention:

Seek immediate medical help if you experience severe leg weakness, loss of sensation in the leg, or sudden bladder or bowel incontinence, as these can be signs of a more severe condition.

UC San Diego Health made history recently during an anterior cervical spine surgery.

The health system became the first in the world to perform the procedure using a fully personalized implant designed for a patient’s unique anatomy.

The anterior cervical spine surgery, which is one of the most common spine procedures, involves making an incision in the front of the neck, removing a damaged disc and fusing the adjacent vertebrae together.

A standard artificial disc, or traditional implant, is placed in the space where a damaged disc has been removed, according to UC San Diego Health. Traditional customized implants are created through advanced imaging, artificial intelligence (AI) and 3D printing.

“Every spine is unique, just like a fingerprint,” said Joseph Osorio, MD, PhD, associate professor of neurological surgery at University of California San Diego School of Medicine and neurosurgeon at UC San Diego Health. “With this technology, we can create an implant specifically for each patient, instead of asking their body to adapt to a standard device. It’s a fundamental shift in how we approach complex spine surgery.

UC San Diego Health claims the new technological approach allows for more precise spinal alignment, reduced surgical complications and faster recovery times for those suffering from conditions like spinal stenosis, degenerative disc disease, or spinal deformities.

“This is the first step in a larger transformation,” Osorio said. “We envision a future where every implant, whether for the spine, hip, or knee, is made for one person, not mass-produced for everyone.”

💡Interesting facts about the cervical spine:

Humans and giraffes both have seven cervical vertebrae, the same number as most mammals. The first vertebra is the atlas, named after the Greek god who carried the world, because it supports the weight of your skull. The second vertebra, the axis, has a unique pivot point that allows for the rotation of your head to say "no".

• Same number as giraffes: A surprising fact is that giraffes and humans have the same number of cervical vertebrae (seven). Most mammals share this trait, with the exceptions being sloths and manatees.

• The Atlas and Axis: The first vertebra, called the atlas (C1), is a ring-shaped bone that holds your head up. The second vertebra is the axis (C2), which has a special projection called the odontoid process or dens that the atlas pivots against, allowing you to turn your head.

• "Vertebra prominens": The seventh cervical vertebra (C7) is unique because it has a long, palpable spinous process at the base of the neck, which is why it's called the "vertebra prominens". This is similar to the spinous processes of the thoracic vertebrae.

• Unique shapes: While C1 and C2 are very unique, the third through sixth cervical vertebrae are similar to each other in structure.

• Supports the brain: The cervical vertebrae protect the spinal cord and also carry the vertebral arteries that supply blood to the brain.

• Flexibility and risk: The cervical spine's flexibility allows for a wide range of motion for head and neck movements, but this increased mobility also makes the cervical spine more vulnerable to spinal cord injuries.

• No disc between C1 and C2: Unlike other vertebrae, there is no intervertebral disc between the atlas (C1) and the axis (C2).

Our Story

SASPINE (Surgical Associates in Spine) is one of the nation’s most elite spine practice management companies. We now have offices in Houston as well as the San Antonio medical center. Our CMO, Steven J. Cyr, M.D., is a spine surgeon who has gained a reputation for surgical excellence in Texas, throughout the nation, and abroad. All of our providers are experienced at isolating the source of pain and accurately diagnosing and treating symptoms and conditions using both non-operative and operative means. We strive to treat the whole patient from the onset of pain to post-surgical rehabilitation.

Our philosophy is to seek conservative, non-surgical solutions for a patient’s neurological, muscular, or skeletal problems first. If non-surgical treatment fails to provide significant pain relief and surgery is required, our patients benefit from surgical procedures provided by world-class surgeons, including Dr. Steven J. Cyr, who trained at the prestigious Mayo Clinic in Rochester, Minnesota. The Mayo clinic spine fellowship is a combined fellowship providing both neurosurgical and orthopaedic expertise to its fellows, making them experts in treating cervical, thoracic, and lumbar spine conditions. Both the Neurosurgery and Orthopaedic departments have consistently been ranked number 1 in the country for more than 20 years. This unique approach provides patients with a level of care provided by few surgeons in the world. As a previous collegiate athlete, bodybuilder, and Orthopaedic surgeon, Dr. Cyr’s unique background enables him to understand the source of muscular and skeletal issues unlike many others. Coupled with fellowship training in Orthopaedic and Neurosurgery of the spine, his ability to diagnose the source of pain and identify solutions to address it are rare.

Dr. Cyr previously served in the United States Air Force as the Chief of Spine Surgery and Spine Surgery Consultant to the Surgeon General and the Pentagon. Dr. Cyr was also an assistant professor to the orthopedic surgery residents, physician assistant fellows, and medical students at Wilford Hall Medical Center and the Uniformed Services University of the Health Sciences. His extensive experience includes treating Level 1 trauma victims and combat injured Soldiers, Airmen, Sailors, Marines, and civilians during two tours to Iraq during Operation Enduring Freedom. This experience provided him with skills rarely seen in the private sector. His training also allowed him the opportunity to lend innovative techniques to the military. Dr Cyr performed the first total disc replacement procedure as well as endoscopic spinal surgery in the Air Force in addition to surgery for degenerative disc disease, herniated discs, failed back syndrome (revision surgeries for failed operations), spine trauma, scoliosis surgery, and cancer of the spine. He specializes in addressing complicated spine issues and has gained notoriety for successful repairs of failed surgeries on patients from numerous other states and around the world. He is a member of the Society for Minimally Invasive Spine Surgery but believes every patient must be evaluated individually and a treatment plan tailored to that patient’s diagnosis crafted to provide the best outcome, which commonly involves open procedures.

Dr. Cyr and his mid-level providers, who are hand-picked and specially trained by him, define success by the number of people who are able to live a better quality of life after treatment. In attention to his methodical and meticulous approach to surgical excellence, Dr Cyr is a man of character and compassion who believes in treating patients like family. This reputation is apparent in the heart-felt testimonies regularly provided by patients who have received his care. In addition, he has become world renowned as a premier provider of spine surgery with success rates rarely seen elsewhere. He has been named a Texas Super Doctor, Castle-Connelly Top Spine Surgeon multiple years in a row, and America’s Top 10 Orthopaedic surgeons, amongst many other recognitions and awards. We are excited to show you the SASPINE difference. Come see for yourself what sets us apart.
