Minimally Invasive Spine Fusion
Advanced spinal fusion using small incisions for faster recovery and less tissue damage.
Using innovative technology, a minimally invasive surgery (MIS) spinal fusion can now be accomplished using two small poke-hole incisions with minimal tissue dissection, resulting in a faster recovery. Using the MIS procedure, Posterior lumbar fusions (PLF) and transforaminal lumbar interbody fusions (TLIF) can both be performed in less time, with less tissue damage, and less pain than traditional open spinal fusion surgery.
Overview and Indications
Posterior Lumbar Fusion (PLF) is the general term used to describe the technique of surgically mending two or more lumbar spine bones together along the sides of the bone. Minimally invasive PLF is generally always performed in conjunction with instrumentation (metal screws/rods) to impart immediate stability while the bone mends.
MIS TLIF includes the PLF described above, as well as performing an interbody fusion, which means the intervertebral disc is removed and replaced with a bone spacer. MIS PLF and MIS TLIF are commonly performed for conditions such as spondylolisthesis and degenerative disc disease.
Surgical Technique
The surgery is performed utilizing general anesthesia. A 1-inch poke-hole incision is made on each side of the low back, directly over the involved spinal levels. The fascia and muscle is gently divided using special cannulated retractors and sleeves. The pedicle screws and rods are implanted and the facet joints are fused through the two tiny incisions under x-ray guidance.
Post-Operative Care
Most patients are usually able to go home 1–3 days after surgery. Before patients go home, physical therapists and occupational therapists work with patients and instruct them on proper techniques of getting in and out of bed and walking independently.
Patients are instructed to avoid bending at the waist, lifting (more than five pounds), and twisting in the early postoperative period (first 2–4 weeks). Patients can gradually begin to bend, twist, and lift after 4–6 weeks as the pain subsides and the back muscles get stronger.
Results
The results of Minimally Invasive Spinal Fusion surgery are generally excellent. Numerous research studies demonstrate greater than 92–98% good or excellent results from MIS fusion surgery. Most patients are noted to have a significant, rapid improvement of their back pain and return to many, if not all, of their normal daily and recreational activities.
