Spine surgery worldwide market, sales growth rates of products

Demonstrating a very wide range of clinical approaches and technologies, products used in spine surgery range from the very well established to products demonstrating considerably more potential than actual, current sales.

The products in spine surgery include:

  • Posterior Pedicle Screw Fusion Systems
  • Anterior Cervical Plate Systems Anterior Thoracolumbar Systems
  • Anterior Lumbar Interbody Fusion
  • Thoracolumbar Interbody Fusion
  • Posterior Lumbar Interbody Fusion
  • Axial Lumbar Interbody Fusion
  • Interspinous Process Spacers
  • Cervical Artificial Discs
  • Lumbar Artificial Discs
  • Vertebroplasty
  • Balloon Kyphoplasty
  • Allografts
  • Demineralized Bone Matrices
  • Bone Morphogenic Proteins

Spine fusion systems represent the most well established products in spine surgery.  Novel and/or emerging technologies include artificial discs, vertebroplasty and kyphoplasty.  The more novel use of allografts, demineralized bone matrices and bone morphogenic proteins offer considerable promise, but clinical challenges have limited their more rapid growth.

Below are illustrated the relative growth rates (comparing CAGR from 2012 to 2020) of spine surgery products. (We are providing the growth rates represented graphically with the absolute values of the growth rates not shown on the x-axis to simply illustrate the relative growth rates.)

Clinical utility of advanced wound closure and securement products

Products for the advanced securement of wounds — stopping bleeding, sealing the wound, tightly closing the wound and preventing post-surgical adhesions — will be accepted by clinicians (and paid for by healthcare systems) to the extent that the provide very specific clinical utility compared to traditional alternatives, many of which (like sutures and tapes) are simple to use, cost little and otherwise are readily accepted in the business of wound management.

Clinicians (and healthcare systems) will accept and adopt for routine use those new products for hemostasis, closure, sealing and anti-adhesion of wounds, whether chronic or acute, based on the level of clinical utility they provide compared to those traditional products, and the extent to which those new products provide utility is based on the types of utility provided (from “critical” to “perceived”), a metric that varies by clinical specialty.  For example, a new product that prevents bleeding and dramatically reduces morbidity is much more likely to be adopted than a product that yields merely aesthetic (e.g., reduced scarring) or perceived benefits that have no impact on morbidity.

Advanced products offer different degrees of utility from, on the high end, the value of enabling procedures otherwise not possible or highly impractical to, on the low end, perceived benefits with no significant positive impact on morbidity.  Further, the impact of advanced products varies by clinical specialty, with some expected differences between, for example, cardiology procedures and cosmetic procedures. The four main categories of benefit from advanced products include:

  • Important and Enabling: Important to prevent excessive bleeding and transfusion, to ensure safe procedure, and to avoid mortality and to avoid complications associated with excessive bleeding and loss of blood.
  • Improved Clinical Outcome: Reduces morbidity due to improved procedure, reduced surgery time, and prevention of complications such as fibrosis, post-surgical adhesion formation, and infection (includes adjunct to minimally invasive surgery).
  • Cost-Effective and Time-Saving: Immediate reduction in surgical treatment time and follow-up treatments.
  • Aesthetic and Perceived Benefits: Selection is driven by aesthetic and perceived benefits, resulting in one product being favored over a number of medically equivalent treatments.

Below is illustrated the distribution — by clinical category — of the kind of utility provided by advanced wound securement products (fibrin and other sealants, high strength adhesives, hemostatic products and anti-adhesion products):

Wound management market trends

Underscoring the evolution of wound care as a distinct medical specialty, manufacturers are looking to design and market patient-centered, best practice-based products that address clinical and fiscal concerns. One area of concern is pressure ulcer prevention and treatment — a high priority in terms of a growing population of elderly and increasingly stringent reimbursement regulations.

A major trend underlying medical technology development is a focus on making products more cost effective. One way to keep costs low is to design products that extend wear time, reducing the expense of labor while preserving quality of care. One example is 3M™ Tegaderm™ High Performance Foam Adhesive Dressing, an extended-wear dressing that manages exudate over a longer period of time; the dressings are designed to adhere while exudate evaporates out of the dressing. To address concerns that longer wear time can thwart the ability to assess wound healing, newer clear products (eg, 3M™ Tegaderm™ Absorbent Clear Acrylic Dressing) allow visualization of the wound beneath the dressing. Unlike traditional dressings, these new dressings do not need to be pulled back to monitor healing progress — plus, they remain clean and do not compromise skin integrity.

Other cost-lowering options include designing more concentrated products so less is needed and making some products available as single-dose packets to control the spread of infection and reduce waste. In addition, innovations in multidose packaging will feature new delivery systems that allow the patient to carry the product throughout the care continuum.

Ease of use is a consideration for several reasons. Clinician turnover, especially in long-term and home care, is a challenge in terms of technique training and mastery. To help clinicians more easily identify specific products depending on patient need, 3M recently updated its Cavilon™ Professional Skin Care product line with new packaging. Also, multilayer compression for venous ulcers involves the ability to wrap several layers of dressing. Some products are applied at 50% of full strength; for the inexperienced practitioner, this may be difficult to gauge. 3M’s Coban™ 2 Layer Compression System is applied at full strength to reduce application variability and to ensure the patient receives the proper amount of compression, regardless of clinician skill with compression wrapping.

Patient comfort continues to be a critical consideration, not just in terms of dressing fit and wear time, but also with regard to ingredients. As such, fragrance-free products with no added scents are gaining global popularity.

To ensure patient-centered, best practice-based care, companies know they must provide not just cost-effective products, but also a great deal of tech support that facilitates product ease of use. Manufacturers must be cognizant of and responsive to patient and caregiver needs and prove, repeatedly and with conviction, that while it is subject to the ebb and flow of trends, quality of care is not “trendy.”

Product development focus appears to fall within several distinct categories, based on the nature of different wound needs and the benefits wound management products might provide:

  • Surgical Wounds
  • Traumatic Wounds
  • Burns
  • Chronic Wounds

Wound management challenges fall along the spectrum of least to highest difficulty from surgical wounds (clean wounds with defined margins and managed clinically at onset) to traumatic wounds (frequently involving multiple layers and more surgical intervention to manage) to burns (multiple layers and possible grafting need) to chronic wounds (high product use to manage exudate, moisture, infection, other challenges).

Dominated by a few companies, advanced wound closure still has upside for new players

The global market for products in “wound securement”, or the aggregate of products that are related to the closure and healing of wounds, is dominated by traditional products — sutures and the more recent clips and staples.  However, as simple and effective as these are, particularly since their use is engrained in the skillsets of practicing surgeons, advances in wound closure, hemostasis and even anti-adhesion are challenging the entrenched positions of suture, staple and clip suppliers.  Fibrin and other sealants have found acceptance in use by surgeons seeking tighter wound sealing, faster healing, less scarring and other benefits.  Hemostatic agents have proven highly versatile (in a range of clinical settings from the OR to the battlefield) in rapidly stopping bleeds in a way that traditional wound closure cannot. The end result of surgery also demands that the surgery itself cause a minimum of complications, and products in anti-adhesion (many actually being sealant products that are actually effective in what one might consider the “opposite” role) have proved effective in this capacity.

But old habits die hard, so very high caseload of wound closure is still addressed via sutures, staples and clips.  Consequently, the global market for wound closure and related products has companies like Ethicon (J&J) holding big pieces of the pies.
