What Is Posterior Lumbar Decompression and Fusion with Instrumentation?
PLDFI is a surgical procedure designed to reduce pressure, alleviate pain, and stabilize the bones in the lumbar region of the spine, commonly referred to as the lower back. This procedure relies on using a decompression technique combined with a chosen fusion technique to address symptoms of spinal conditions in the lower back, providing long-term relief and preventing further spine degradation.
Who is a candidate for PLDFI?
A candidate for posterior lumbar decompression and fusion with instrumentation is typically a patient suffering from chronic, debilitating lower back pain and/or leg pain caused by conditions such as lumbar spinal stenosis, spondylolisthesis, degenerative disc disease, or spinal instability. This surgical procedure is generally considered when non-surgical treatments like physical therapy, medications, and injections have failed to provide adequate relief. Ideal candidates are those experiencing persistent pain, neurological symptoms like numbness or weakness in the legs, and a reduced quality of life due to their spinal condition.
PLDFI with Posterior Lumbar Interbody Fusion (PLIF)
Posterior lumbar decompression and fusion with posterior lumbar interbody fusion (PLIF) is performed under general anesthesia to ensure your comfort throughout the duration of the procedure. A SpineCare of NY surgeon will access the spine through a midline back incision. Next, they will remove part of the lamina (laminectomy) and extract the damaged disc material. Bone graft material is then placed in the disc space to complete the decompression portion of the surgery. Fusion is then done with specialized implants like rods and screws, which are inserted into the affected vertebrae to maintain stability. The procedure aims to decompress nerves, stabilize the spine, and promote vertebral fusion, typically taking several hours depending on the case complexity and number of vertebral levels treated. This surgery’s ultimate goal is to reduce pain and improve function for the patient.
PLDFI with Transforaminal Lumbar Interbody Fusion (TLIF)
Posterior lumbar decompression with transforaminal lumbar interbody fusion (TLIF) is performed under general anesthesia. To begin, your surgeon makes an incision in the middle of the lower back to access the spine. After retracting the muscles, a portion of the lamina is removed (laminectomy) to expose the compressed nerves. The surgeon then accesses the disc space through the foramen, the opening where nerves exit the spine, removing the damaged disc material. A bone graft or cage is inserted into the empty disc space to restore height and relieve nerve pressure. Fusion using screws and rods is done to stabilize the spine. Additional bone graft material may be added along the sides of the spine to promote further fusion. The procedure aims to decompress the nerves, stabilize the spine, and encourage vertebral fusion, typically taking several hours depending on the complexity and number of levels treated.
PLDFI with PLIF or TLIF Recovery and Results
The results and recovery from posterior lumbar decompression and fusion with instrumentation (PLDFI) using either posterior lumbar interbody fusion (PLIF) or transforaminal lumbar interbody fusion (TLIF) techniques are generally favorable. Studies have shown good to excellent outcomes in 90-96% of cases, with significant improvements in back pain and return to normal activities for most patients. Recovery typically begins with a hospital stay of 1-3 days when a minimally invasive approach is used. Patients usually require pain medication for 1-2 weeks post-surgery and can often return to work and start driving within 2 weeks. The total recovery period ranges from 6 to 12 weeks, with more rigorous activities resuming after about 3 months. However, individual healing processes and the number of vertebrae fused can affect recovery time. While complications are uncommon, potential risks include nonunion, persistent pain, infection, and hardware-related issues.
