A pedicle subtraction osteotomy (PSO) is a surgical procedure used in adults and children to correct certain deformities of the spine. A spine with too much kyphosis (forward curvature, or “hunchback”) or too little lordosis (inward curvature, or “swayback”) can be corrected with a PSO.

The PLIF technique includes performing a wide laminectomy and bilateral partial facetectomy to allow visualization and removal of the intervertebral disc. The TLIF technique includes performing a complete unilateral (one side only) facetectomy to allow visualization and removal of the intervertebral disc.

Anterior lumbar interbody fusion (ALIF) is a spine surgery that involves approaching the spine from the front of the body to remove disc or bone material from in between two adjacent lumbar vertebrae. The procedure may be performed either as an open surgery or using minimally invasive techniques.

Listen to pronunciation. (PEH-dih-kul …) A type of surgery used to rebuild the shape of the breast after a mastectomy. Tissue, including skin, fat, and muscle, is moved from one area of the body, such as the back or abdomen, to the chest to form a new breast mound.

There are several types of spinal fusion surgery options. The most commonly employed surgical techniques include: Posterolateral gutter fusion – the procedure is done through the back.

Conclusions: The available evidence suggests that both TLIF and PLIF could achieve similar clinical satisfaction and fusion rate in the management of degenerative lumbar diseases. However, TLIF was superior to PLIF with shorter operation time, less blood loss, and lower incidence of nerve root injury and dural tear.

Lumbar fusion surgery is major surgery. Most patients having TLIF surgery will stay in the hospital for between one to three days. Physical therapy then begins the day after surgery. You will have to limit your activity, making sure to avoid twisting the spine, but walking during your recovery will be important.

In general terms ALIFs (anterior lumbar interbody fusion) and PLIFs (posterior lumbar interbody fusion) have a success rate of about 70%. Success itself is not easy to define, but I suggest to my patients that they have a good chance of a significant reduction of pain.

Anterior lumbar interbody fusion, P/TLIF, and combined surgical costs were $75,872, $65,894, and $92,249, respectively (p<. 0001). Patients in the P/TLIF cohort had the greatest number of comorbidities, having the highest prevalence for 10 of 17 comorbidities investigated.

Pedicle subtraction osteotomy (PSO) is a posterior-based osteotomy that requires resection of the posterior elements, pedicles, and decancellation of the vertebral body in a V-shaped fashion through the transpedicular corridor ( FIG 1B ).

A PSO requires a wide laminectomy from the pedicle above to pedicle below the osteotomy level, resection of the bilateral pedicles at the PSO level, and vertebral body decancellation to the anterior vertebral body in a wedge shape.

Smith-Petersen osteotomy (SPO) is a chevron resection of the posterior elements that shorten the posterior column and lengthen the anterior column upon closure (FIG 1A). The chevron osteotomy is called a Smith-Petersen osteotomy if performed through a prior fusion or a Ponté osteotomy if done through a nonfused spinal segment.

The osteotomy hinges on the anterior column with closure of the middle and posterior columns creating a large cancellous bone footprint for fusion. A thorough understanding of spinal anatomy including spinal cord, nerve root, and vertebral segments is needed to safely perform these procedures.
