A few minutes with Dr. Dwight Tyndall on his approach to spine care — and what patients can expect.
Dr. Tyndall performs minimally invasive spine surgery at the state-of-the-art Lakeshore Surgicare ambulatory surgery center — calmer than a hospital, often lower cost, and you recover at home the same day. See what your day at the surgery center looks like.
Dr. Tyndall sees patients at the state-of-the-art Lakeshore Bone & Joint Institute in Crown Point. Take a look inside.
"Dr. Tyndall is amazing! I went to him for severe sciatica. After a minimally invasive discectomy, I was back to work in just two weeks, completely pain-free."
"I highly recommend Dr. Tyndall and his team. He explained my cervical disc replacement options so clearly and performed my surgery flawlessly. Highly skilled and compassionate."
"Thanks to Dr. Tyndall's surgical expertise, I was discharged same-day and experienced very minimal pain. I'm finally active again after years of back problems."
"Personable, intelligent, outgoing and so very medically knowledgeable. It was an honor and a learning experience to be with Dr. Tyndall and his impressive and kind staff."
"Cares, knowledgeable, excellent work on my back fusion — no pain! Carrie the nurse is just fabulous! The whole team made me feel comfortable and confident in my care."
"Dr. Tyndall and his staff are wonderful! This was my first visit and I was very impressed. He took the time to listen, explain everything clearly, and made me feel at ease about my treatment options."
Back and neck symptoms rarely fit neatly into a box. Dr. Tyndall identifies what is actually driving the pain, then considers the least invasive path forward.
Not sure where to begin? Request an evaluation →Disc material pressing on a spinal nerve can cause pain, numbness, or weakness that travels into an arm or leg.
Care may include physical therapy, injections, or minimally invasive microdiscectomy.
Narrowing around the spinal nerves often leads to leg pain, cramping, numbness, or difficulty walking and standing.
Care may include epidural injections or minimally invasive laminectomy.
Changes in the spinal discs can produce persistent back or neck pain, stiffness, and reduced mobility.
Care may include physical therapy, lifestyle medicine, or artificial disc replacement.
A vertebra slipping forward can create instability and compress nerves, causing back pain or radiating leg symptoms.
Care may include bracing, physical therapy, or minimally invasive stabilization.
A pinched nerve in the neck or lower back can cause tingling, numbness, pain, or weakness in the arms or legs.
Care may include nerve blocks, foraminotomy, or disc replacement.
Persistent or recurring pain deserves a fresh, comprehensive evaluation—not a one-size-fits-all answer.
Care may include diagnostic review, revision planning, or complex salvage surgery.
Operating with real-time computerized navigation.
Small incisions and advanced computerized navigation minimize muscle damage, leading to faster healing, less postoperative pain, reduced blood loss, and smaller scars. Dr. Tyndall was the first surgeon in Indiana to use computerized navigation for outpatient MISS.
Explore MISS →Many spine procedures, including disc replacements, can be performed safely in an ambulatory surgery center, allowing you to recover at home the same day. This approach leads to less surgical pain, faster recovery, and a better patient experience.
Explore Same-Day Surgery →Motion-preserving alternatives to spinal fusion. The damaged disc is replaced with an artificial disc that maintains your spine's natural flexibility, reducing stress on adjacent levels and avoiding the limitations of fusion.
Explore Disc Replacement →An ultra-minimally invasive technique using tiny endoscopes to treat herniated discs, spinal stenosis, and nerve compression through the smallest incisions possible — often under 1 centimeter.
Explore Endoscopic Surgery →Targeted decompression procedures to relieve pressure on spinal nerves. Microdiscectomy removes the herniated portion of a disc; laminectomy removes a small portion of bone to widen the spinal canal.
Explore Decompression →When fusion is necessary for spinal stability, Dr. Tyndall uses the latest minimally invasive fusion techniques. He also has expertise in complex revision surgery for patients who have had unsuccessful previous spine operations.
A minimally invasive procedure to treat vertebral compression fractures. A small balloon is used to restore vertebral height, then bone cement is injected to stabilize the fracture and relieve pain.
