The revolution in the global market of spinal implants

The world market of implants destined to orthopedic surgery and traumatology has experienced during the last years a strong period of expansion, linked in good measure to the development of new products and to the increase of the sanitary cost in the main developed countries. Thus, in the last decade the average annual variation rate stood at around 15%, with the market accounting for 19 trillion dollars at the end of the period. The forecasts for the next decade point to growth of the same order in a context of an increase in the percentage of older people and the maintenance of the aforementioned factors that explain the favorable evolution of the last decade.

Other factors such as increased incidence and prevalence of spinal disorders; development of technologically advanced, safe and cost-effective spinal devices; global increase in old age and the obese population; and the growing demand for minimally invasive spine surgery are driving the growth of the spinal implant market and surgical devices. However, factors such as strict regulations for the sale of state-of-the-art medical devices, high processing costs and the lack of adequate reimbursement in developing countries can restrict the growth of spinal implant market if adequate measures are not taken on time.

From the point of view of the products, the segment of knee implants reached in 2014 a volume of 5.9 trillion dollars, that is, 20.5% of the total value. It is followed by hip implants, with 4.5 trillion dollars, and spinal implants, with 4.3 trillion dollars, so that these three segments account for just over 55% of the total value of the global production of implants destined for orthopedic surgery and traumatology. The structure of the offer maintains a high concentration around seven multinational companies, mostly of American origin. This group of operators maintains a quota in the world market close to 85% of the total value.

Pedicle Screw System

According to recent studies, there is a direct relationship between technological innovation measured in the number of patents and the growth of income and employment of companies in the area. Likewise, the characteristics of the generated patents, which enjoy great commercial applicability, allow estimating that close to 90% of them could be the embryo of new companies that exploited the development of that patent.

Implant companies have seen an increase in the weight of electronic commerce in recent years. Thus, in 2017 most of the US hospitals, whose number is estimated at 6,800, made use of this supply system, mainly for the acquisition of medical devices. The volume of operations managed through this mechanism represents 10% of the total of 100,000 million euros that hospitals spend annually on medical and surgical supplies, pointing out the tendencies to a strong and sustained growth.

The US market for the conservation of spinal mobility devices is estimated to reach $ 3540 million by 2018.Likewise It is estimated a double-digit growth in the global market for minimally invasive surgery (MIS) which further drives the global market for implant spine; a clear example is the spinal fusion, which corresponds to a surgical procedure that prepares two adjacent vertebral bodies to fuse, forming a fused bone. The new Mobility Preservation Devices allow preserving the natural movement of the spine, unlike the spinal fusion techniques used previously.

Mobility conservation technologies are believed to revolutionize minimally invasive surgery (MIS) for spinal fusion, a sub-segment of the spinal fusion market, consisting of devices and procedures associated with less invasive surgery. Posterior screw / rod and intersomatic devices are implanted with minimal surgical damage to the patient, leading to faster recovery times. The number of MIS procedures is estimated to grow by 18% until 2015.

It is important to bear in mind that an adequate combination of private initiatives (entrepreneur spirit, trained human capital, developed business fabric) and direct government support to companies (favorable economic environment, development of adequate infrastructures) are the fundamental axes for further promote the implant market for orthopedic surgery and traumatology.

Orthopedic Surgery: A Comprehensive Overview

The surgery about musculoskeletal system in human bodies is referred to as orthopedic surgery. The surgeons can use surgical and non-surgical methods to treat problems related to joints, bones, muscles, nerves, and ligaments in the human body. The kind of treatment which is adopted varies from person to person. The orthopedic surgeons are capable of resolving problems involving injuries, spine disorders, degenerative diseases, sports injuries, tumors, hip and knee reconstructions and infections of various kinds. However, going to a surgeon doesn’t qualify one for a surgery straight away. Most of the times the patient is treated using various non-invasive techniques and medicines only.

Surgery And Risks Involved

Most of the doctors who enter the field of orthopedic surgery chose one of the following fields of specialization:

• Arthroscopy
• Joint Replacement
• Musculoskeletal Oncology
• Pediatric
• Rehabilitation
• Reconstructive Surgery
• Spine
• Sports Medicine
• Trauma and Fractures

While most of the procedures that are performed come without any possible risk but the ones that involve a surgery do come with certain limitations like any surgical procedure does. Some of the common risks involved with orthopedic surgeries involve:

Anesthesia: The type of anesthesia that is given depends on the type of surgery which is being performed. There are a lot of different types of anesthesia ranging from local to general and the risks of anesthesia vary with the type which is being selected.

Infections: Most of the surgical procedures especially the invasive ones will require good post-operation care. This is to avoid infections of any sort from developing in the body. Most of these infections are easy to manage, and some might require further surgeries to handle as well. The risk of infections is higher in surgeries that involve hip or joint replacement procedures.

Blood clot: A blood clot can form anywhere in a vein after surgery. If it is in the veins, the clot is fairly risk free. However, if it travels to the lungs, it can cause severe breathing issues and would require prompt medical care. Doctors make use of blood thinners and other medicines to eliminate the risks of blood clots in bodies.

Choosing The Right Orthopedic Surgeon

When choosing an orthopedic surgeon, it is important to make sure of a few things first.

• The doctor should have specialized in the area your problem is related to.
• All the necessary equipment and medications should be available for the procedure
• You have a clear idea of the procedure and how it will be performed. Ask all the necessary questions before-hand. Discuss with your doctor the different types of anesthesia and how one is different from the other.

If it is a surgery that your condition requires, make sure that not only the surgery but your post-operation care is up-to-the-mark as well. There are a lot of new techniques being introduced every other day which eliminate the chances for surgery. Make sure you have discussed and researched about them all before you decide on a surgical procedure with your orthopedic surgeon.

Your Complete Guide to Spinal Implants

Surgery is not required in most of the spinal conditions, however, there are times when it becomes very important for the patient to undergo one. Unique and specially designed spinal instrumentation used in the spinal implants are an integral part of all the surgical processes. One can expect these implants to provide strength to the spine and stabilize it, fix the deformities, and facilitate fusion.

The special conditions which might give rise to the need for surgery include traumatic fracture, slippage of the spine, scoliosis, and chronic degenerative disc disease apart from numerous other critical spinal instabilities.

What Are Implants?

Metals like titanium, stainless steel, and titanium-alloy are used to manufacture spinal implants whereas there are some which are made from non-metallic compounds. Patients of different ages and sizes can easily be accommodated because of the variety of shapes available in these implants.

Scientists all over the world are working hard to bring further improvements to these implants so that they can result in more favorable outcomes. In quite a few years, some breakthroughs have been achieved in this regard and they include the development of special plates, the creation of small implants for children, and enabling the doctors to correct the deformities 3-dimensionally.

The different groups of these implants are:

Rods

These rods are really strong along with being flexible which allows the surgeon to contour them according to the need of the patient while bringing alignment to the spine.

Pedicle Screws

These are the strong points which provide a place for attachment to the rods. Initially, they were used in lumbar spine only but the advancements in technology have enabled the surgeons to use them in thoracic spine as well.

Hooks

Used for anchoring purposes along with rods and other kinds of implants.

Plates

The plates help in conforming to the contouring of the spine. Screws which are adjusted in adjacent vertebrae tend to hold them in place. They can be contoured in the future as well depending on the anatomy of the patient.

Cages

Having perforated walls, these are minute hollow devices. If the height of a disc is lost because of a collapse, then cages can be used for restoration purposes and the pressure on the nerve roots is also relieved.

How To Use These Implants?

The use of these implants depends on a great volume of the specific needs of a particular patient. Titanium implants are said to be resilient and light along with allowing usage with MRIs. Low volume and low profile implants are the best options which sometimes are not visible through a scan but the bone forming and bone fusion can be inferred.

Future Of These Implants

Scientists are keenly working on bioresorbable implants which are completely gone in the matter of time when the problem is resolved. They are designed in a way that they break down when they come in contact with water.

The better treatments for patients are surfacing every now and then but the scope and usage of any kind of treatment depends a great deal on the needs of the patients.

Ѕріnаl Fuѕіоn, Different Types And Hоw Sріnаl Fuѕіоn Ѕurgеrу Is Dоnе

Whаt іѕ sріnаl fuѕіоn?

A ѕріnаl fuѕіоn is ѕіmрlу the uniting оf twо bоnу ѕеgmеntѕ, whether a frасturе or a vеrtеbrаl jоіnt. Thе rеаѕоn for іnѕtrumеntаtіоn with rоdѕ and screws іѕ tо асt as аn ‘іntеrnаl саѕt’ tо stabilize thе vеrtеbrа until thе fusion, оr bоnу re-growth, can оссur.

Sріnаl fuѕіоn is a “wеldіng” process by whісh two оr mоrе оf thе ѕmаll bоnеѕ (vеrtеbrае) thаt mаkе uр thе ѕріnаl column аrе fuѕеd tоgеthеr wіth bone grаftѕ аnd іntеrnаl dеvісеѕ ѕuсh аѕ mеtаl rods tо hеаl іntо a single ѕоlіd bone.

Dіffеrеnt types оf spinal fuѕіоn ѕurgеrу

Antеrіоr іntеrbоdу ѕріnаl fusion іѕ performed vіа an іnсіѕіоn іn a раtіеnt’ѕ аbdоmеn. The vеrtеbrаl bodies аrе approached frоm thе frоnt аnd a fеmоrаl ring (саdаvеr bоnе), оr суlіndrісаl саgе, іѕ рlасеd between thе two vertebral bodies. Thе fеmоrаl rіng оr саgе instrumentation іѕ filled wіth bone graft uѕuаllу оbtаіnеd frоm the раtіеnt’ѕ hip (iliac сrеѕt).

Hоw iѕ sріnаl fuѕіоn ѕurgеrу dоnе?

Thеrе are mаnу surgical approaches аnd methods tо fuse thе ѕріnе, аnd they аll іnvоlvе placement оf a bоnе graft bеtwееn thе vеrtеbrае. Thе spine mау bе аррrоасhеd аnd thе graft placed frоm thе back (роѕtеrіоr аррrоасh), from thе front (anterior approach) оr by a соmbіnаtіоn of bоth. In thе neck, thе аntеrіоr аррrоасh is mоrе common; lumbar and thoracic fusion is uѕuаllу реrfоrmеd роѕtеrіоrlу.

The ultimate gоаl of fuѕіоn іѕ tо оbtаіn a solid unіоn between twо оr mоrе vertebrae. Fuѕіоn mау оr mау nоt involve use оf supplemental hаrdwаrе (іnѕtrumеntаtіоn) such аѕ plates, ѕсrеwѕ аnd саgеѕ. Inѕtrumеntаtіоn is sometimes used to соrrесt a dеfоrmіtу, but uѕuаllу іѕ juѕt uѕеd аѕ аn іntеrnаl ѕрlіnt to hold the vertebrae tоgеthеr to whіlе thе bоnе grаftѕ hеаl.

The bоnе may bе tаkеn еіthеr frоm аnоthеr bone іn thе раtіеnt (аutоgrаft) оr from a bоnе bаnk (allograft). Fusion using bоnе taken from thе patient hаѕ a long hіѕtоrу оf uѕе and rеѕultѕ in рrеdісtаblе healing. Autograft is сurrеntlу thе “gоld standard” source of bоnе fоr a fusion. Allograft (bоnе bаnk) bоnе mау bе uѕеd as аn alternative tо thе patient’s оwn bone. Althоugh healing and fusion іѕ not аѕ predictable аѕ with thе раtіеnt’ѕ оwn bоnе, аllоgrаft dоеѕ not rеԛuіrе a ѕераrаtе іnсіѕіоn tо take thе patient’s own bone fоr grаftіng, аnd therefore іѕ аѕѕосіаtеd wіth lеѕѕ pain.

Phуѕісаl thеrару аnd rеhаbіlіtаtіоn іѕ gеnеrаllу rеԛuіrеd and can be a ѕоmеwhаt lengthy process.

 

Types of Spinal Implants

Spinal problems are increasing rapidly nowadays, mainly due to our sedentary lifestyle and other postural and physical habits. Most of the spinal problems can be treated by non-surgical procedures, but sometimes surgery is the only option that includes the use of specially designed spinal implants.

Conditions requiring spinal implants:

These implants can correct deformities, reduces pain, neurological defect and helps to stabilize the spine. Conditions requiring spinal implants include disc slip, degenerated disc, spinal tumor, spondylosis, fracture of the vertebrae, posterior rami syndrome and spinal instability such as scoliosis and kyphosis. In the cervical spine, most common problems are compressed nerve root or herniated disc while in lumbar spine kyphosis and scoliosis are the main problems. All these issues can be corrected by spinal implants.

Spinal Implants:

The spinal implants are made from titanium, alloy or steel which is stainless, and some from non-metals (plastics). They are especially designed in various shapes and sizes so that they may fit in different patients of various ages and sizes.

Research is being done in this field to further refine the implants that work more accurately. With the invention of screw, rods and hooks, surgeons are able to treat deformed spine in all the three dimensions. The specific type of plates and small sized implants are being designed for spinal fusion and for children respectively.

Types of Spinal Implants:

1) Fusion implants:

Fusion implants are used with bone grafts and it includes; rods, screws, plates, hooks and cages.

Rods:

Rods have been used since the advent of the implants. The purpose of these rods is to make the affected segments of the spine non-mobile for the accurate alignment of the spine. Rods are made up of titanium or stainless steel, but it is flexible, which allows the surgeon to fit the rod according to the contour of the spine.

Screws:

These are called pedicle screws because they are fixed in the pedicles of the vertebra. They are used for the lumbar segments, but because of the ongoing progress in this field, it is also being used for thoracic spine. Rods should be fixed according to the contour of the spine and for that purpose screws are used as they provide anchorage points for rods.  In this way, it promotes fusion and removes deformities.

Hooks:

Hooks are used with rods; they help in anchoring them and other implants to the vertebrae.

Plates:

Plates are used with screws so that it may be held in place in a vertebra. Plates are adjusted according to the size of the patient and for that purpose, contouring tool may be used.

Cages:

Cages are used mostly for collapsed disc and nerve root impingement. These are small devices. These are placed between vertebrae and a bone graft may be packed between them to promote the growth of the affected vertebral column.

2) Non-fusion implants:

These are not combined with bone grafts. Examples are; Growth-sparing devices and artificial discs. These growth sparing devices are used in children who have the growing skeleton.

Conclusion:

It is better to use low-volume and low-profile implants so that they are not visible through the skin and there is no post-operative pain. Titanium is better as it is light and can be seen on MRI. Progress is being made in this field so that better results can be obtained.

Your spinal cord is a bundle of nerves that keeps running down the center of your back. It conveys signals back and forward between your body and your cerebrum. A spinal cord injury upsets the signals. Spinal cord injuries ordinarily start with a blow that dislocates or cracks your vertebrae, the bone circles that make up your spine. Most injuries don’t slice through your spinal cord. Rather, they cause damage when bits of vertebrae tear the cord tissue or press down on the nerve parts that convey signals.

Spinal cord injuries basically can be divided into complete and incomplete. With a complete spinal cord injury, the cord can’t send signals below the level of the injury. Therefore, you are paralyzed below the injury. With an incomplete injury, you have some development and sensation below the injury.

A spinal cord injury is a therapeutic emergency. Prompt treatment can diminish long term complications. Medications may incorporate pharmaceuticals, traction to balance out the spine, and surgery. Later treatment typically incorporates prescriptions and rehabilitation treatment. To get around and do some everyday tasks, mobility aids and assisting devices are important.

The ability to control your appendages after spinal cord injury relies on upon two components: the place of the injury along your spinal cord and the seriousness of injury to the spinal cord. The most minimal piece of your spinal cord that functions typically after injury is alluded to as the neurological level of your injury.

Paralysis from a spinal cord injury might be alluded to as:

• Tetraplegia-Otherwise called quadriplegia, this implies your arms, hands, trunk, legs and pelvic organs are all influenced by your spinal cord injury.
• Paraplegia-This paralysis influences all or part of the trunk, legs and pelvic organs.

Your doctor will perform a progression of tests to decide the neurological level and fulfillment of your injury. Spinal cord injuries of any sort may bring about one or a greater amount of the accompanying signs and manifestations:

• Exaggerated reflex spasms
• Loss of movement
• Loss of sensation, including the ability to feel warmth, chilly and touch
• Trouble breathing and coughing
• Loss of bladder or bowel control
• Changes in sexual function and fertility
• Pain or an exceptional stinging sensation created by damage to the nerve filaments in your spinal cord

Emergency signs and symptoms of spinal cord injury may include:

• Intense back pain or weight in your neck, head or back
• Imbalance and trouble walking
• Weakness, paralysis or in-coordination in any body part
• Numbness, shivering or loss of sensation in your hands, fingers, feet or toes
• A strangely positioned or contorted neck or back
• Loss of bladder or bowel control
• Disabled breathing after injury

Any individual who encounters huge injury to his or her head or neck needs prompt therapeutic assessment for the likelihood of a spinal injury. Truth be told, it’s most secure to accept that trauma victims have a spinal injury until proven otherwise since:

• A severe spinal injury isn’t generally promptly obvious. In the event that it isn’t perceived, more serious injury may happen.
• Paralysis or numbness may grow promptly or go ahead continuously as swelling and bleeding happens in or around the spinal cord.
• The time between injury and treatment is important in measuring the complications and the amount of possible recovery.

Unfortunately, there’s no real way to invert damage to the spinal cord. However researchers are working progressively on new therapeutic methods, including prostheses and prescriptions that may advance nerve cell recovery or enhance the function of the nerves that stay after a spinal cord injury. spinal cord injury treatment are generally focused on averting further injury and enabling individuals with a spinal cord injury to come back to a dynamic and beneficial life.
