Transforaminal lumbar interbody fusion (TLIF) is an advanced form of spinal fusion procedure carried out on the lower back. It involves removal of two intervertebral discs and joining two or more spinal vertebrae together with the help of spinal cage and screws. The goal of TLIF procedure is to create a solid bone between two or more vertebrae, which can stop the movement between the bones, reducing the pain and inflammation internally. The procedure is recommended for the stabilization of the vertebrae when the spine is unstable. The TLIF procedure primarily involves decompression of the nerves in the lower back, removal of facet joints and intervertebral discs, and stabilization of the level of discs by insertion of the pedicle screws. The fusion of the spine is done by inserting a cage into a disc space. The high rate of fusion success, and more precise transforaminal decompression are the major factors expected to boost the TILF market during the forecast period. However, risks associated with post-surgical complications are likely to be a restraint for the TILF market during the forecast period.
The global TLIF market can be segmented into procedure type, and type of screws. In terms of procedure type, the TLIF market can be segmented into open surgery and minimally invasive surgery types. Open surgery accounted for a prominent share of the market in 2016, which is attributed to the rising prevalence of orthopedic disorders, ease of access to the vertebral portion of the body through a big and open incision, and low cost of the procedure. However, minimally invasive surgery type is expected to witness significant CAGR during the forecast period. The segment is anticipated to lead the market by 2025. The dominance is attributed to the increasing adoption of technologically advanced surgical procedure by surgeons, low probability of post-surgical complications, and better correction of the deformity in the vertebrae. In open surgery, the surgeons makes an incision through the middle of the lower back, cuts away & retracts the spine muscles to make the vertebrae & disc space accessible for the procedure. However, in minimally invasive surgery, a physician inserts a tube from the specific portion of the body, and perform complete surgical operations through the tube, using special surgical instruments.
In terms of screw type, the global TLIF market can be segmented into polyaxial screws, monoaxial screws, and cannulated screws. The monoaxial screws & polyaxial screws segments cumulatively held more than half of the market share in 2016 due to the reduced damage caused by them to the internal spinal muscles, causing less blood loss. However, the polyaxial screws segment is projected to expand at a significant CAGR during the forecast period. It is anticipated to lead the TLIF market by 2025. The dominance is attributed to their high resistance to corrosion, availability in various sizes, and their compatibility with an MRI scan.
Geographically, the global TLIF market can be segmented into North America, Europe, Asia Pacific, Latin America, and Middle East & Africa. In terms of revenue, North America held a prominent share of the global TLIF market in 2016, which is attributed to the rising demand for minimally invasive surgical procedures by patients, and availability of trained & expert physicians in North America. Asia Pacific is estimated to expand at a prominent CAGR during the forecast period due to rising incidence of road accidents and the increasing success rate of the procedure. However, North America is expected to maintain its dominance of the global TLIF market during the forecast period due to the rising per-capita expenditure of the population on the healthcare sector.
Prominent players operating in the global TLIF market include NuVasive, Inc., Zimmer Biomet, Stryker Corporation, Ulrich Medical, Z-Medical GmbH + Co. KG, and Medtronic.
