The research study covers the present scenario and growth prospects of the global motion preservation market for 2016-2020. Based on product, the market is segmented into the following: cervical artificial disc, lumbar artificial disc, and interspine spacers.
New products with two level disc replacement application in
cervical spines are going to be the next trend in the market. Such
devices are expected to boost the
cervical artificial discs segment. In August 2016 LDR, a medical device company, announced that the FDA had approved the sales and distribution of its artificial disc replacement product named Mobi-C Cervical Disc. This is the only device approved in the US for use in one- and two-level disc replacement in the cervical spine.

Technavio analysts highlight the following three factors that are contributing to the growth of the global motion preservation market:
- Increased prevalence of spinal disorder patients
- Effective stability facilitation in artificial spine implants
- Growing preference of advanced nucleus arthroplasty
Increased prevalence of spinal disorder patients will increase usage of motion preservation surgeries
The incidence of spinal disorders such as herniated discs, DDD, spondylolisthesis, prolapsed intervertebral disc, and spinal stenosis is on the rise worldwide. Though these disorders affect people of all ages, most individuals aged 60 years and above are susceptible to them. “Aging causes the cartilage between the facet joints to deteriorate, leading to various spinal disorders. A rise in the population of this age group will increase the prevalence of spinal disorders, particularly scoliosis and spondylolisthesis,” says Srinivas Sashidhar, a lead orthopedics and medical devices research analyst at Technavio.
In 2013, a statistical report by the UN estimated that 841 million people worldwide were aged 60 years and above, accounting for 11.7% of the global population. This number is likely to increase to two billion by 2050. This rise in the cases of spinal disorders will increase the volume of spinal implant surgeries to relieve pain and preserve spinal motion.
A 2015, a clinical study in Saudi Arabia stated that lumbar spinal disorder can affect people of all ages. The study included 1,669 individuals with spinal disorders, of which about 52.9% had lumbar spinal disorders.
Thus, growing prevalence of spinal disorders among the geriatric population has increased the demand for cervical artificial discs globally.
Age ranges of most common spinal disorder
|Spine disorder name||Age (Males)||Age (Females)|
|Lumbar disc degeneration||50-54 years||55-59 years|
|Lumbar disc hemiation||45-49 years||45-49 years|
|Cervical disc degeneration||50-54 years||50-54 years|
|Cervical disc herniation||45-49 years||45-49 years|
|Sciatica||45-49 years||50-54 years|
|Cervical Spondylosis||50-54 years||50-54 years|
Effective stability facilitation in artificial spine implants drives adoption of surface-modified titanium
Titanium is increasingly used as an alternative metal over stainless steel to manufacture cervical spinal implants. Titanium implants are strong, lightweight, and have minimum interference during computed tomography (CT) and magnetic resonance imaging (MRI) after implantation as compared to stainless steel. “Also, titanium implants maintain a porous structure on the inner surfaces, promoting the integration of bone for enhanced fusion and retroserrated toothing on the caudal and cranial surfaces of the implant that provides effective primary stability,” adds Srinivas.
Growing preference of advanced nucleus arthroplasty motion preservation technology that shows fastest recovery
Nucleus Arthroplasty is an advanced technology in motion preservation technology that has a novel treatment approach. In this technology, the degenerated nucleus of patients is replaced by surgical intervention. The main purpose of nucleus arthroplasty surgery is to maintain geometry of the index intervertebral disc and prevent adjacent segment degeneration by preserving the motion. This technology shows better patient outcome (specially in young individuals) compared to fusion surgeries and better management of DDD.
