What is Spine Replacement?

What is hip replacement surgery? 

Hip replacement surgery is a medical procedure in which a damaged or diseased hip joint is replaced with an artificial joint, known as a prosthesis. This surgery is typically performed to relieve pain and improve function in cases of severe arthritis, hip fractures, or other conditions affecting the hip joint. The prosthetic hip joint is designed to mimic the natural movement of the hip, allowing for improved mobility and reduced discomfort.

 

Types of hip replacement surgery? 

Various types of spine surgery are as follows:

  • Cervical disc replacement: During this procedure, a surgeon removes damaged disc portions or the entire disc and replaces it with a bone graft or artificial parts. The common benefits of this surgery include more mobility, quicker recovery, improved function, and lower risk of future pain.
  • Discectomy: This surgery involves the removal of a portion of a herniated or bulging disc that is pressing on spinal nerves, causing pain and other symptoms.
  • Foraminotomy: During this surgical procedure, a surgeon widens the area around the bones in the spinal column. This surgery helps in relieving the pressure on compressed spinal nerves.
  • Spinal laminectomy: A laminectomy surgery involves removing all or part of the lamina (the back part of the bone that covers your spinal canal). The aim of this surgery is to decrease compression to the spinal cord. Laminectomy is a common spinal stenosis treatment.
  • Microdiscectomy: It is a minimally invasive procedure in which a surgeon removes pieces of a herniated or ruptured disc to relieve back pain.
  • Lumbar discectomy: A lumbar discectomy is spine surgery involving an injured disc in the patient’s lower back region. There are two types of lumbar discectomy: minimally invasive arthroscopic discectomy and open spine surgery. Open spine surgery is the more common procedure for a herniated disc in the lumbar area.
  • Vertebroplasty/ Kyphoplasty: A kyphoplasty treats a compression fracture. The surgeon uses a balloon and special cement to stabilize the bone. The procedure restores some height to the compressed vertebrae (bones that form your spinal column).
  • Foraminotomy: This surgery enlarges the space where spinal nerves exit the spinal canal, relieving nerve compression caused by conditions like spinal stenosis or foraminal stenosis.
  • Artificial Disc Replacement: This surgery involves replacing a damaged or degenerated spinal disc with an artificial disc, allowing for continued motion at the affected spinal level.

Spinal fusion: Spinal fusions permanently connect two or more vertebrae. You may need a spinal fusion to treat spinal instability, scoliosis, or a herniated disc. During a spinal fusion, the surgeon connects two adjacent vertebrae in order to avoid pain caused by their movement against each other. The surgeon uses small screws and rods to connect the vertebrae, and they are then left to heal and fuse together naturally. The physician may also take a small bone graft from another part of your body to help the vertebrae fuse

 

What is spine surgery? 

Spine surgery refers to surgical procedures performed on the spine to address conditions such as herniated discs, spinal stenosis, fractures, or deformities. The goal is often to relieve pain, stabilize the spine, or treat neurological issues by correcting abnormalities in the spine's structure. Common types include spinal fusion, discectomy, and laminectomy. It's important to note that surgery is usually considered after non-surgical treatments have been explored.

 

Types of spine surgery? 

There are various types of spine surgery, each addressing specific conditions or issues. Some common types include:

Spinal Fusion: Joins two or more vertebrae to stabilize the spine, often used for conditions like degenerative disc disease or spinal instability.

Discectomy: Removes a portion of a herniated disc that may be pressing on nerves, alleviating pain and reducing inflammation.

Laminectomy: Involves removing part of the vertebral bone (lamina) to relieve pressure on the spinal cord or nerves, commonly used for spinal stenosis.

Foraminotomy: Enlarges the openings where nerve roots exit the spinal canal, addressing issues like foraminal stenosis.

Vertebroplasty and Kyphoplasty: Procedures to treat vertebral compression fractures by stabilizing and strengthening the affected vertebrae.

Artificial Disc Replacement: Involves replacing a damaged or degenerated disc with an artificial one, aiming to maintain spinal flexibility.

Microdiscectomy: A minimally invasive procedure to remove a portion of a herniated disc, typically with smaller incisions and quicker recovery.

Spinal Cord Stimulator Implantation: Involves placing a device near the spine to deliver electrical impulses, helping manage chronic pain.

The choice of surgery depends on the specific condition, its severity, and individual patient factors. Always consult with a healthcare professional to determine the most suitable treatment approach.
