Interbody (IB) devices are designed to replace the intervertebral discs of the spine, which enhances stability in the region and promotes fusion between the two vertebral bodies. These devices are threaded, allowing them to be used in conjunction with bone graft material. Over time, the packed graft is gradually replaced by natural bone, forming a solid piece. IB fusion procedures typically add a posterior fixation device to the associated level. These procedures are often referred to as 360° fusions, as surgeons will implant interbody devices from an anterior approach and flip the patient over to implant a posterior pedicle screw device. This combination increases the fusion success rate over an interbody fusion device implantation without the addition of fixation devices.

Motion preservation devices are an exciting and often controversial segment of the spinal implant market. These devices are used for treating pathologies similar to those that spinal fusion procedures address. However, unlike spinal fusion, motion preservation devices act to preserve the natural motion of the spine. Some motion preservation devices are used for treating pathologies that were previously untreatable with traditional fusion procedures, thus creating new markets for spinal implants.

Electrical stimulation devices are used for stimulating bone growth after a spinal fusion procedure. Spinal electrical bone growth stimulators are often used as an adjunct therapy in order to increase the chance of a successful solid spinal fusion. In the United States, electrical stimulation devices are designed specifically for lumbar and cervical fusions. However, some lumbar devices have historically been used off-label to augment the healing process for cervical fusion procedures.

Spinal instrumentation is used to stabilize the spine during fusion procedures, typically by lessening the pressure put on the spine until successful fusion has occurred. This ensures that bone growth does not occur in a way which further impedes proper movement, and that growth is as efficient as possible. As a category, spinal instrumentation includes a wide variety of products, including fixation products discussed in the cervical and thoracolumbar fixation segments of this report.

Spinal fusion is a surgical procedure designed to combine two or more vertebrae together, eventually forming a fused bone. Spinal fusion is primarily used for eliminating or significantly reducing the pain caused by abnormal movement of the vertebrae through immobilization. Supplemental bone tissue, either autograft or allograft, is used for promoting bone tissue growth. Fusion is accomplished by using either an instrumented or non-instrumented surgical approach. Instrumented fusions incorporate fixation devices to secure and stabilize the fusion site and interbody devices to fill the intervertebral disc space as well as enhance and promote fusion. Non-instrumented fusions use bone tissue to promote growth but do not incorporate any implant devices into the procedures. Interbody device markets, including those used in the thoracolumbar region of the spine, are discussed in a subsequent chapter. All procedures and markets in this analysis are instrumented fusions because they involve the implantation of plates, screws, rods, wiring or cable fixation devices.

A vertebral compression fracture (VCF) occurs when the bone tissue of the vertebral body collapses in the spine. There are various causes of VCFs, but the most common is osteoporosis. Typically, the lumbar region of the spine is affected, resulting in the anterior section of the vertebral body collapsing. This can cause the spine to tilt forward. In multi-level cases, kyphosis (hunchback of the spine) can result from a VCF. In addition, VCFs can result from malignancy, infection or trauma to the spine.

The total orthopedic navigation system market includes the capital equipment, LUA and services and maintenance revenue market segments. For the purposes of this report, the LUA market segment includes navigation-specific disposable, reposable and reusable devices. The capital equipment market segment includes the surgical navigation platform cost and the cost of the orthopedic software application. The capital equipment market segment does not include the cost of surgical imaging systems.

The full report suite on the global market for ear, nose and throat (ENT) navigation systems includes three segments: capital equipment, limited use accessories (LUA) and services and maintenance revenue. Regional volumes of ENT procedures using a navigation system are also reported.

Overall, the global spine navigation system market was valued at $402.8 million in 2021. This is expected to increase over the forecast period at a CAGR of 18.6% to reach $1.3 billion.

The full report suite on the global market for minimally invasive surgery (MIS) robotic systems includes three segments: capital equipment, limited use accessories (LUA) and services and maintenance revenue. Regional volumes for robotic-assisted MIS procedures are also reported.

The elbow naturally operates as a hinge joint, with the majority of the natural range of motion occurring on one plane, although it also includes a rotational component. The joint involves the articulation of three bones: the humerus, the radius and the ulna. The articulation of the head of the radius on the ulna allows for forearm pronation and supination, resulting in the ability to rotate the wrist.

There is a greater variety of treatments available for hand and wrist conditions compared to larger anatomical areas of the body. The distinction between traumatic devices and reconstructive devices are a bit obscured, as there is overlap in indications. This is especially true for anatomies that are distal to the wrist joints. In particular, the distal radius plate market, which is almost solely used for traumatic fracture treatment, is also used for reconstruction of the hand and wrist. The hand and wrist market is segmented into wrist fusion devices and distal radius plates.

Shoulder devices are considered a small joint in this report; however, they are sometimes classified as large joints because they are often marketed in a similar manner to hip and knee implants, but have historically exhibited market revenue growth rate similar to devices for the distal extremities.
Shoulder reconstruction devices discussed in this report include: total shoulder implants, reversed-shoulder implants, partial shoulder implants and shoulder implant revisions.

The full report suite on the global market for robotic-assisted neurosurgery systems includes two segments: capital equipment and services and maintenance revenue. Regional volumes of robotic-assisted neurosurgery procedures are also reported.

The full report suite on the global market for robotic radiosurgery systems includes two segments: capital equipment and services and maintenance revenue. Regional volumes of robotic radiosurgery procedures are also reported.

The orthopedic segment of the IGS market has the greatest overall potential because of the sheer number of procedures performed due to the population growth, a growing elderly population, and increasing obesity rates in India. Over the forecast period, the use of orthopedic IGS systems is set to make inroads into sport orthopedics, expanding to include more shoulder and knee procedures.
