The aim of the study is to observe and document surgical practice and evaluate patients' outcomes following a MAST™ single or double level instrumented fusion procedure using PLIF (Posterior Lumbar Interbody Fusion) or TLIF (Transforaminal Lumbar Interbody Fusion) techniques for the treatment of the degenerative lumbar spine in a "real-world" patient population.
Instrumented lumbar fusion is usually done through an open procedure which involves an excessive intraoperative dissection and retraction of the paraspinal musculature leading, in a short term basis, to a prolonged recovery time from the surgery. This open approach is frequently associated with significant blood loss and need of transfusion, produces the majority of the perioperative pain, increases hospital stay and the chances of infection and delays the return to normal activities and to work. In a long term basis, the open procedure leads to denervation, atrophy and loss of the muscles independent function, resulting in an increased risk of "fusion disease", a term that has been coined to describe its occurrence.
The minimally invasive spinal surgery was developed as a potential solution to the above-mentioned problems by reducing the amount of iatrogenic soft tissue injury while reaching the same traditional goals of the open procedures. Besides minimizing the long-term effects of exposure-related muscle injury, minimally invasive lumbar fusion techniques hold the promise of immediate short-term advantages. Patients undergoing minimally invasive procedures are reported to recover earlier from the surgery. Shorter time to first ambulation, less pain medication consumption, less blood loss, less required transfusion, shorter hospital stay and earlier return to work are generally associated with the minimally invasive procedure as compared to the standard open surgeries. The minimally invasive access requires a surgical corridor targeted on the disease which is accomplished by using a series of tubular muscle dilators allowing a clear intraoperative visualization to perform these procedures together with the parallel use of image guided percutaneous insertion of pedicle screws and instrumentation.
The purpose of this study is to observe and document surgical practice and evaluate patients' outcomes following a MAST™ single or double level instrumented fusion procedure using PLIF or TLIF techniques for the treatment of the degenerative lumbar spine in a "real-world" patient population.

Inflammation of the SACROILIAC JOINT. It is characterized by lower back pain, especially upon walking, fever, UVEITIS; PSORIASIS; and decreased range of motion. Many factors are associated with and cause sacroiliitis including infection; injury to spine, lower back, and pelvis; DEGENERATIVE ARTHRITIS; and pregnancy.
A condition of persistent pain and discomfort in the BACK and the LEG following lumbar surgery, often seen in patients enrolled in pain centers.
The anterior concavity in the curvature of the lumbar and cervical spine as viewed from the side. The term usually refers to abnormally increased curvature (hollow back, saddle back, swayback). It does not include lordosis as normal mating posture in certain animals ( = POSTURE + SEX BEHAVIOR, ANIMAL).
Acute or chronic pain in the lumbar or sacral regions, which may be associated with musculo-ligamentous SPRAINS AND STRAINS; INTERVERTEBRAL DISK DISPLACEMENT; and other conditions.
The replacement of intervertebral discs in the spinal column with artificial devices. The procedure is done in the lumbar or cervical spine to relieve severe pain resulting from INTERVERTEBRAL DISC DEGENERATION.
