Spinal intervention involves the treatment of all maladies that afflict the spine. The aim of spinal intervention is pain management, wherein the focus is solely on the spine. The spine consists of 33 bones, which include 12 thoracic vertebrae, seven cervical vertebrae, five sacral vertebrae, five lumbar vertebrae, and four coccygeal vertebrae. The pedicle, which is a stub of a bone that connects the lamina to the vertebral body to form an arch, is crucial in spinal intervention, as it offers a safe and secured tunnel. Through this tunnel, the interventionist examining the spine can get safe access to the vertebral body for vertebroplasty, biopsy, and kyphoplasty. The pedicles located in the cervical area are small and they have poor access to the vertebral body. The size of the pedicles gradually increases from the upper thoracic spine i.e. T4 to the lower lumbar spine i.e. L5. Progressive angulation occurs toward the cervical area from T4. Therefore, both pedicle size and angulation are equally important while planning a transpedicular procedure during intervention.
Spinal decompression is performed to create sufficient space for the nerves in the spinal canal, thereby diminishing the pain caused by neural impingement. Spinal fusion is performed to stop movement at one or more vertebral segments so as to relieve the pain and correct the spinal instability. The aim of spinal fusion is to unwind the spinal nerves that cause pain. This helps restore an appropriate gap between the vertebrae that surround the diseased disc, eliminating the pain caused during movement of the affected part.
Increase in the incidence of complications associated with the spine is one of the factors expected to increase health care costs worldwide. Other major factors are rise in the incidence of neurological diseases and neck deformities caused by obesity and injuries and increase in the incidence of degenerative disc disease, spondylolisthesis, prolapsed intervertebral circle, herniated disc, and spinal stenosis. The global spinal intervention market is expected to expand significantly in the next few years, due to high investments by major players in R&D activities and availability of government funds for promoting advanced technologies. However, lack of skilled, highly qualified, and well-experienced medical practitioners; high costs of surgery; and lack of awareness among patients about diagnosis are expected to be restraining factors for the global spinal intervention market during the forecast period.
The global spinal intervention market can be segmented based on surgery type, procedure type, technology, end-user, and region. Based on surgery type, the market can be segmented into open surgery and minimally invasive (MI) surgery. Due to occurrences of unsuccessful spinal surgeries, speedy research in newly developed techniques has been started to improve the outcome. Advancements in percutaneous techniques used in interventional procedures have lowered the invasive nature of the surgery. They have also avoided issues involved in open surgery such as infection and scarring. Based on procedure type, the global spinal intervention market can be classified into laminectomy, corpectomy, facetectomy, discectomy, and foraminectomy. Facetectomy is a procedure performed to remove the facet cartilage with the spine, which can promote easy fusion of bones. Non-fulfilment of this procedure can leave the facet articular cartilage inside, which may block the bone fusion by permitting the movement and contact between two cartilaginous surfaces in the particular part. Discectomy is a procedure allowing the removal of the herniated disc from the spinal canal. Laminectomy is a back surgery procedure performed to release the compressed spinal cord. Corpectomy is a procedure that helps relieve the damage caused to the vertebrae and the intervertebral discs. Foraminectomy is a spinal surgery procedure that decompresses the spinal nerves strained by the tissues, the disc material, or the bone that has narrowed the foraminal canal. Based on technology type, the global spinal intervention market can be classified into spinal fusion technology, spinal fixation technology, spinal non-fusion technology, annulus repair, dynamic stabilization, artificial disc replacement (or disc nucleus replacement), and vertebral compression fracture treatment. Based on end-user, the global spinal intervention market can be segregated into hospitals, research centers, and others.
Geographically, the global spinal intervention market can be divided into five major regions: North America, Asia Pacific, Europe, Latin America, and Middle East & Africa. The market in North America is expected to lead the global market during the forecast period, due to increasing number of spinal surgeries in countries in the region.
