Orthopedic Surgical Techniques

ACL reconstruction is one of the most common knee surgeries. “ACL” stands for anterior cruciate ligament. It connects your thighbone to your shinbone with a twist in the middle and helps stabilize your knee. Most injuries happen during sports and activities in which sudden stopping, pivoting or landing causes the ACL to tear.

With ACL reconstruction, a surgeon replaces the damaged ACL with another piece of similar tissue, typically taken from another part of the patient’s knee or thigh. Surgeons make a small incision in the front of the knee, usually less than a centimeter, and inserts an arthroscope, which is a thin tube attached to a video camera. This allows doctors to see inside the knee while surgery is underway. There are newer techniques that have been developed over the last 10 years that allow surgeons to better reconstruct the ACL in a more “anatomic” fashion, including anteromedial portal drilling. This better restores the natural anatomy and is why it’s important to see a sports-fellowship trained surgeon.

Through the anterior approach to hip replacement, the hip joint is accessed from the front of the hip rather than from the side or back of the hip. The benefits of anterior hip replacement include: 

  • Shorter time in surgery
  • Decreased hospital stay
  • Shortened recovery time
  • Reduced post-operative pain
  • Less scarring
  • Rapid return to normal activities
  • Full weight-bearing after surgery
  • A natural fit for long-term success

The last several decades have seen significant advances in arthroscopic surgery, a minimally invasive technique used to diagnose and treat joint problems. Dignity Health Medical Group - Merced's orthopedic surgeon repairs and reconstructs joints using highly specialized instruments inserted through small incisions about half an inch long. Arthroscopic surgical procedures are used to lessen pain, reduce recovery time and allow a patient to regain the full use of the joint. Some arthroscopic procedures are also used in conjunction with open procedures to make the overall procedure less invasive.

For those suffering from moderate or advanced arthritis, joint replacement surgery restores freedom of movement and brings dramatic pain relief. These procedures require an orthopedic surgeon to remove the arthritic or damaged joint and replace it with an artificial composite usually made of titanium, surgical steel and polyethylene—a high-density plastic that is strong, durable and smooth. After recovery, patients are usually able to walk and resume their prior level of daily activities without pain or stiffness.

Spine surgery near you

From non-surgical treatment options to the latest minimally invasive procedures, our experienced orthopedic team is committed to getting you back to living a pain-free and active lifestyle. And, if physical therapy is necessary, our team works closely with other specialists to coordinate additional care. If back or neck pain is slowing you down, isn't it time you get back to life?

For some back, spine, and neck injuries, like spinal fractures or herniated discs, spine surgery is the only treatment option to repair damage and prevent injury. Spine surgery is also sometimes used as a treatment for chronic back pain that has persisted for several months and not responded to other types of treatment like pain medication, physical therapy, or bracing. Spine surgery in these cases is typically only recommended after other options have been exhausted.

Before recommending surgery, your doctor will likely assess your condition and symptoms using one or more of the following tools:

  • Patient history. Your doctor will probably want to know how long you have experienced back pain, whether an injury like a fall preceded your symptoms, where the pain is located, and how much it has been limiting your daily activities.
  • Physical exam. Next, your doctor will visually look at and feel your spine for any signs of injury, such as swelling or bruising.
  • Imaging tests. If your medical history suggests a trauma-related injury such as a broken bone (fracture), your doctor will likely use x-ray scans to look at your bones and assess your condition. Other standard scans include MRIs, PET, and CT, which can also provide a picture of your soft tissues and nerves.

Spine conditions treated

At Dignity Health Medical Group - Merced, CA, we treat a variety of spine conditions:

  • Degenerative disc disease. When the joints of the spine wear out, usually due to the natural aging process, which can cause pain in the neck, shoulders, arm, or back.
  • Herniated disc. Occurs when the soft center of a spinal disk pushes through a crack in the tougher exterior casing. A herniated disk can irritate nearby nerves and result in pain, numbness, or weakness in an arm or a leg.
  • Spinal fractures. Such as compression fractures, burst fractures, and fracture-dislocations are breaks in the vertebrae of the spinal column.
  • Spinal stenosis. A chronic condition that occurs when the spinal canal narrows, putting pressure on the spinal cord and nerves.
  • Spinal osteoarthritis. Occurs when the cartilage that protects the bones wears down, causing the bones to rub together, and is the most common type of arthiritis that affects the spine.
  • Spondylolisthesis. A displacement of a vertebra in which the bone slides out of its proper position onto the bone below it, typically following a break or fracture.
  • Sciatica. Or lumbar radiculopathy, is pain that starts in the lower back and radiates down the leg, usually on one side. It is caused by injury to or pressure on the sciatic nerve, and can also cause weakness, numbness, or tingling in the leg.
  • Spinal deformities. Such as scoliosis and kyphosis, involve problems of the curve or rotation of the spine.

Types of spine surgeries offered

Orthopedic surgeons at Dignity Health Medical Group - Merced, CA offer the following types of spine surgery:

  • Laminectomy. A procedure to remove the back of the vertebra, relieving pressure on the spinal cord
  • Laminotomy. A procedure to remove only a portion of the back of the vertebra
  • Discectomy. A procedure to remove a herniated disc to relieve pressure on the spinal nerves
  • Spinal fusion/lumbar fusion. A procedure to connect two or more vertebrae to limit movement and reduce pain  
  • Lumbar surgery. Surgery on the lower (lumbar) spine
  • Disc replacement.
