Common types of orthopaedic surgeries
- Joint Replacement (Arthroplasty): Replacing a damaged joint with an artificial one, most commonly the hip, knee, or shoulder, often due to arthritis.
- Fracture Repair: Using methods like pins, plates, or screws to fix broken bones and ensure proper healing.
- Arthroscopy: A minimally invasive procedure using a small camera and instruments to diagnose and repair issues inside a joint, such as a torn ACL.
- Spinal Surgery: Procedures to correct spinal problems, including fusions to stabilize vertebrae (common for scoliosis) and discectomies to remove a herniated disc.
- Hand and Wrist Surgery: Procedures to repair fractures, tendons, or address conditions like carpal tunnel syndrome.
- Foot and Ankle Surgery: Surgeries for a wide variety of issues, from Achilles tendon tears to bunions and arthritis in the toe, or realigning bones after a fracture.
- Soft Tissue Repair: Procedures to repair damaged muscles or tendons.
- Corrective Surgery: Procedures to correct problems with anatomical alignment.
- Joint Fusion: Fusing bones to relieve pain and provide stability, often in joints that are too damaged for replacement.
Minimally Invasive Surgery
Minimally invasive neurosurgery uses small incisions or natural openings to treat conditions like brain tumors, aneurysms, and spine disorders, leading to reduced trauma, faster recovery, less pain, and lower complication rates compared to traditional open surgery. Techniques often involve tiny cameras (endoscopes) and specialized instruments guided by advanced imaging like real-time iMRI, iCT, and robotic systems.
Techniques and approaches
- Keyhole craniotomy: Accessing the brain through a small, keyhole-sized opening in the skull.
- Endoscopic surgery: Using a flexible or rigid endoscope passed through a natural opening, such as the nose (endonasal surgery) or eye socket (transorbital surgery), to access lesions.
- Endovascular neurosurgery: Using a catheter to access blood vessels in the brain, often from a puncture in the groin, to treat issues like aneurysms.
- Percutaneous spinal techniques: Using a series of tubes or ports to access the spine, which allows surgeons to work through a small incision.
- Deep brain stimulation (DBS): Implanting a device that sends electrical impulses to regulate brain activity, used for movement disorders like Parkinson’s disease and epilepsy.
Advantages
- Reduced trauma: Minimizes disruption to surrounding tissues and muscles.
- Faster recovery: Patients often experience a shorter hospital stay and can become mobile sooner.
- Less pain: Typically involves less postoperative pain and a reduced need for pain medication.
- Lower complication rates: Reduced blood loss and lower risk of infection.
- Improved aesthetics: Can leave less noticeable scars, or no scars if natural orifices are used.
Other surgeries
Minimally invasive surgery (MIS) is a procedure that uses small incisions and specialized instruments, like a camera on a laparoscope, to perform operations with less trauma to the body than traditional open surgery. This approach offers several benefits, including faster recovery, less pain, shorter hospital stays, and smaller scars. While MIS is widely used, it is not suitable for every procedure or patient, and potential risks should be discussed with a surgeon.
How it works
Instead of one large incision, MIS requires only a few small cuts.
Surgeons use long, thin tools and cameras, such as a laparoscope, to perform the procedure inside the body.
A camera on the end of a laparoscope provides a magnified view of the surgical area on a monitor for the surgeon to see clearly.
Advanced forms of MIS use robotic arms controlled by the surgeon to perform the surgery with enhanced precision and dexterity.
In some cases, a gas like carbon dioxide is used to inflate the surgical area, creating space for the surgeon to work.
Benefits of minimally invasive surgery
- Faster recovery:Patients typically recover much more quickly compared to traditional open surgery.
- Less pain:Smaller incisions lead to less pain after the procedure.
- Reduced scarring:Scars are significantly smaller and less noticeable.
- Shorter hospital stay:Many MIS procedures result in a shorter hospital stay or can be done on an outpatient basis.
- Fewer complications:The reduced trauma can lead to a lower risk of complications.
Examples of minimally invasive surgeries
- Laparoscopic cholecystectomy:Gallbladder removal
- Arthroscopy:For joint surgery
- Endovascular aneurysm repair:For repairing abdominal aortic aneurysms
- Colorectal surgery:For conditions of the colon and rectum
- Bariatric surgery:For weight loss
- Spinal procedures:Including decompression, diskectomy, and fusion
Minimally invasive microscopic surgery uses a high-powered microscope and small incisions to perform procedures with less tissue damage, leading to faster recovery and less pain compared to traditional open surgery. The surgeon views a magnified, real-time image from a surgical microscope or endoscope to guide tiny instruments through small incisions. This technique is commonly used in spinal surgery for issues like herniated discs and spinal stenosis, and also in other areas of medicine.
How it works
- Small incisions: The surgeon makes one or more tiny cuts, often less than a half-inch long.
- Viewing: A surgical microscope or endoscope (a thin tube with a camera and light) is inserted through one incision to provide a magnified view of the internal anatomy.
- Image display: The magnified internal view is projected onto a screen for the surgeon to see clearly during the operation.
- Instrument insertion: Specialized, long, and narrow instruments are inserted through other small incisions to perform the surgical tasks.
- Procedure: The surgeon uses these instruments to manipulate tissues and perform the necessary steps, such as removing a herniated disc or a bone spur.
Benefits
- Less tissue damage: The small incisions and precise instruments cause minimal disruption to surrounding muscles and tissues.
- Reduced pain: With less trauma, patients typically experience less post-operative pain.
- Faster recovery: Patients often have a shorter hospital stay and a quicker return to normal activities.
- Less scarring: The small incisions result in less noticeable scars.
Common applications
- Spine surgery: This is a common application, used for conditions such as herniated discs, spinal stenosis, scoliosis, and tumors.
- Other areas: Endoscopic techniques are also used in other parts of the body, such as laparoscopy in the abdomen and arthroscopy in the joints.
