Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Posterior interbody fusion (PLIF), combined with segmental instrumentation, has become increasingly popular since it was first described by Mercer in 1936 and expanded upon by Cloward. More recently however, the transforaminal approach to the intervertebral disc, known as transforaminal lumbar interbody fusion (TLIF), has gained popularity. Originally described by Harms in the late 1990s, the TLIF has arguably developed into the most commonly performed and efficacious posterior interbody fusion method in modern spine surgery.
Transforaminal lumbar interbody fusion (TLIF) utilizes a more lateral window in order to access the interbody space without excessive dural retraction. Theoretical advantages of TLIF include increased fusion success, more complete foraminal decompression, better correction of deformity, and more effective treatment of discogenic pain.
Transforaminal lumbar interbody fusion (TLIF) have demonstrated excellent fusion rates with acceptable complication profiles for treating single and multilevel lumbar disc pathology and instability. TLIF have been shown to be superior to posterolateral fusion alone for deformity correction and more cost effective than anterior interbody combined with posterior segmental instrumentation.

ReSpace TiCell Cage
ReSpace TiCell Cages are anatomically shaped interbody spacer implants with curved contour. These implants intended to be inserted into the intervertebral disc space for intervertebral body fusion. The interbody spacers are designed to restore height and lordotic angle in the spine. The spacers have teeth on the endplate-engaging surfaces to provide stability, resist shear and rotational forces, and to help prevent migration of the spacer within the disc space. The open central cavity on them allows for placement of graft material allowing for subsequent bone growth through the interior of the devices.
ReSpace TiCell Cages are indicated for lumbar spine stabilization (between L.I.-S.I. segments). TLIF spine surgery will be combined with posterior fixation using pedicle screws and rods.

Inclusion Criteria
All subjects who had previously indicated for TLIF surgery can participate in this study, with the following evidence:
1. Has degenerative disease of the lumbosacral spine in one or two adjacent levels (L1 to S1), manifested by:

1. Instability as defined by ≥3 mm translation or ≥5-degree angulation
2. Decreased disc height, on average by ≥2 mm, but dependent upon the spinal level
3. Scarring/thickening of ligamentum flavum or annulus fibrosis
4. Herniated nucleus pulposus
5. Vacuum phenomenon
6.

7. Stenosis, or narrowing, of the lumbar spinal canal and/or intervertebral foramen requiring significant decompression leading to segmental instability, or
8. Recurrent disc herniation
* Skeletally mature adults ages 18 - 80 years of age

Exclusion Criteria

4. Lumbar scoliosis \>30 degrees.
5. Patients who had a previous diagnosis of osteoporosis with a Tscore of -2.5 or below in the last 12 months. If subject has a prevalent fragility fracture and a T-score hasn't been assessed in the last 12 months, a DEXA (dual x-ray absorptiometry) scan will need to be obtained.
6. Morbidly obese, as defined by a Body Mass Index (BMI) \>40.
7. Presence of active malignancy or prior history of malignancy (noninvasive basal cell carcinoma of the skin and non-invasive squamous cell carcinoma localized only to the skin is allowed).

3. Use of NSAIDs and/or steroids for longer than two weeks postoperatively through the 24 Month Follow-Up Visit is not recommended. Such patients must be excluded from data analysis in case of non-fusion.
10. Co-morbidities, which in the investigator's opinion, precludes the subject from being a surgical candidate.
11. Autoimmune disease, which in the investigator's opinion, is known to affect bone metabolism or the spine (e.g., spondyloarthropathies, juvenile arthritis, rheumatoid arthritis, Graves' disease, Hashimoto's thyroiditis).
12. Any endocrine or metabolic disorder, which in the investigator's opinion, is known to affect osteogenesis (e.g., Paget's disease, renal osteodystrophy, Ehlers-Danlos syndrome, or osteogenesis imperfecta).
13. Known hypersensitivity or allergy to any components of the study treatments including, but not limited to bone morphogenetic proteins (BMPs); injectable collagen; protein pharmaceuticals (e.g.: monoclonal antibodies or gamma globulins); bovine collagen products; and/or instrumentation materials (e.g., titanium, titanium alloy, cobalt chrome, cobalt chrome alloy, or PEEK).
14. History of any allergy resulting in anaphylaxis.
15. Is mentally incompetent. If questionable, obtain psychiatric consult.
16.
