The present disclosure relates generally to spinal orthoses, and more particularly, to a mechanically advantaged spinal system, which may be a progressive spinal system. Spinal orthoses are frequently prescribed and worn to limit body motion, to reduce body-realized load, and/or to improve body function, essentially according to accomplishment of the same purpose: 1) compression of the abdomen, 2) limitation of spinal motion, and 3) protection of the torso. Indications of use may include, without limitation, osteoporosis, spondylolysis, burst fracture, spinal stenosis, spondylolisthesis, chronic back pain, degenerative disc disease, herniated or bulging disc, ligament strain/sprain, compression fracture, spinal stabilization, post-laminectomy, or the like. Irrespective of the indication, however, orthosis design necessarily dictates functionality and overall performance.
Typically, orthosis attributes and features are selectively balanced according to the needs of a particular patient, wherein consideration may be given to such features as the overall weight and adjustability of the orthosis, including its ability to accommodate patient size variation, the ease of donning (putting on) and doffing (taking off), the overall functionality and cosmesis (desirable physical appearance), and, as with essentially any medical tool or device, durability of materials and cost. Unfortunately, in spinal bracing, one benefit or attribute must typically be traded to get another, e.g. comfort versus support, rigid control versus softness, and/or custom-like fit versus simplicity.
Functionality and performance are obviously critical considerations; however, the patient must be able to properly and effectively don the device in order for the functionality and performance to be realized. Moreover, patients must be encouraged to regular wear. Mechanically advantaged devices have been introduced to assist in a patient's ability to put on and wear an orthosis, with proper force delivered thereby. Strings and cords that serve to tighten these devices are tensively woven about pulleys or posts. The strings are typically connected to a plurality of pull tabs that a patient must pull bi-directionally away from the body, looped about his or her thumbs. These devices may be effective, but the tightening movement necessary may be outside the range of movement for at least some patients. Moreover, the narrow strings or cords may disadvantageously tangle, fray or jam, and at least some such devices require very particular positioning after patient doffing in order to allow for re-donning with functionality of the tightening system to be retained. And, the added weight and construction complexity of the pulleys or posts, generally installed inside enclosed pockets during manufacture, may impact comfort of wear and cost.
Cost of treatment is frequently an important consideration, first in the initial prescription and purchase, and thereafter during the course of the healing process. That is, over the treatment period, as a patient heals, the necessary level of support and control typically changes. In order to accommodate the changing needs, purchase of one or more additional orthoses may be disadvantageously necessary. Customization of posterior plates' lordosis and kyphosisspecifications, as well, may be disadvantageously prohibitive, wherein a patient is generally relegated to selection of closest general-fit options to his or her needs.
Therefore, it is readily apparent that there is a need for a spinal orthosis system, wherein a comfortable, supportive and cost-effective treatment is enabled, with custom-like fit, mechanically advantaged and easily adjustable force delivery, adaptability to patient healing and progression of needs, simplicity and durability of design, and ease and encouragement of patient use, thereby avoiding the above-discussed disadvantages.
Briefly described, in one embodiment, the present apparatus and method overcomes the above-mentioned disadvantages and meets the recognized need for such a device by providing a mechanically advantaged progressive spinal system, wherein a string- and pulley-free strap arrangement facilitates adjustment of tension and enhances patient delivered muscle strength, wherein posterior plate curvature may be quickly and easily adjusted to best accommodate a patient's lordosis and kyphosis, and wherein modular components allow for adaptation of mobility and support to improving patient needs.
According to its major aspects and broadly stated, the present device is a mechanically advantaged progressive spinal system with modular brace components ranging from an orthopedic belt to a full sagittal-coronal control orthosis, wherein a foundational element is tensively adjusted with a single, unidirectional pull and resulting force delivery from straps rerouted 3:1 and 2:1 for a 6× mechanical advantage, and wherein select posterior plate angles are adjusted with a simple joint and strap feature.
More specifically, the system of the present disclosure can comprise a mechanically advantaged belt and a plurality of plates and shells, functioning as a system of orthotic braces capable of progressively diminishing support and control, and increasing mobility, adapting to patient improvement. Each of the braces of the system serves to compress the abdomen, limit spinal motion, and protect the torso, but they range in height and stiffness to allow for proper support according to the necessary circumstances of patient status. Additionally, the mechanically advantaged belt has two selectable profiles, and may be circumferentially reduced and/or expanded, according to patient size and preference.
According to one embodiment, the belt structure has two general support members of breathable mesh, with a soft patient interface. Each general support member has a plurality of internal structural support elements provided in a spaced-apart configuration; each has an outer surface substantially covered with hook and pile fastener; and each has a pair of straps fixed proximate the inner posterior surface thereof for selective attachment of a posterior plate. The inner anterior surface of one of the two general support members has an accessible pocket, wherein an anterior plate may be selectively carried therewithin. The inner anterior surface of the other of the two general support members has hook and pile fastener complementary to that of the outer surface provided thereon, whereby the two general support members may be removably secured together proximate the front of the body of the patient.
The posterior belt closure mechanism has two closure support members, each removably carried on the outer surface of the outer posterior surface of a respective one of the two general support members. One of the closure support members has the ends of an elongate closure strap affixed thereto, and has two support rings positioned therebetween. The other of the closure support members also has two support rings positioned thereon, wherein the elongate closure strap extends from each of the affixed points on the first closure support member through the support rings of the other closure support member, and back through the support rings of the first closure support member, whereafter the elongate closure strap is looped through a strap connector element. A D-ring cinching strap is affixed to one of the general support members of the belt, serving to activate the 6× mechanical advantage of the closure mechanism, wherein patient muscular pulling force delivered thereto causes slidable movement of the strap connector element there along, thereby delivering a pulling force on the elongate closure strap, tightening the belt, with inverse handling steps for loosening.
According to the needs of the patient, one or more of a plurality of selectable features may be added. For example, an extender may be attached, wherein the anterior plate is pre-drilled to facilitate acceptance thereof. An optional belt panel also may be added to enable accommodation of sizes up to and including 5×. Additionally, in order to facilitate progressive adaptation, pluralities of posterior configurations are possible for use with the mechanically advantaged belt. A first posterior configuration is tailored for aggressive support, with a molded and padded posterior shell adapted with belt retainer straps and a central spinal relief zone. This posterior configuration is also adapted for use with a taller thoracolumbosacral orthosis (TLSO).
Another posterior configuration is used for a standard chairback brace or lumbosacral orthosis (LSO), wherein firm support is enabled by a padded posterior plate with adjustable lordosis and kyphosis straps and belt retainer straps. Yet another available posterior configuration is used for a mid-lumbosacral orthosis (mid-LSO), wherein moderate support is enabled by a padded posterior plate with an adjustable lordosis strap and belt retainer straps. The posterior plates with adjustable lordosis and/or kyphosis are configured as sturdy structures with bend-accommodating regions and adjustable straps related thereto. Each plate may be selectively bent relative to its bend-accommodating region(s), wherein the related adjustable strap may be tightened to enable maintenance of the selected bend during wear of the orthosis.
Thus, a feature and advantage of the present system is its ability to perform a cost-effective orthosis, suitable for utilization throughout an entire treatment period, wherein, for example, a four stage progressive brace system may be followed, with a first stage configuration having a rigid posterior shell deployed with the mechanically advantaged belt having a rigid anterior plate therein, a second stage configuration having a semi-rigid posterior plate and a rigid anterior plate, a third stage having a rigid anterior plate but no posterior plate, and a fourth stage having no anterior or posterior plate.
Another feature and advantage of the present system is its ability to allow for custom-like lumbar lordosis and/or kyphosis fit, without heating or remolding.
Another feature and advantage of the present system is its ability to perform as a mechanically advantaged device operated with one hand.
Yet another feature and advantage of the present system is its ability to deliver at least a 6:1 mechanical advantage.
Still another feature and advantage of the present system is its ability to eliminate risk of tangling, jamming, tearing and/or fraying relative to strings or cords.
Yet still another feature and advantage of the present system is its ability for easy and effective donning and doffing, without necessitating complex stretching or arrangement after doffing and/or prior to donning.
Still yet another feature, and advantage of the present system is its ability to be cost-effectively manufactured.
Yet another feature and advantage of the present system is its ability to tensively adjust without the need for pulleys or posts.
Still another feature and advantage of the present system is its ability to conform to a patient's body with one easy pull.
Yet another feature and advantage of the present system is its ability to enable progressive increase of mobility and decrease of support as a patient improves.
Still yet another feature and advantage of the present system is its ability to be easily disassembled and cleaned.
Another feature and advantage of the present system is that it is MRI compatible.
These and other features and advantages of the invention will become more apparent to one skilled in the art from the following description and claims when read in light of the accompanying drawings.

A cinching strap 116 is carried by general support member 88b, wherein a first end of cinching strap 116 (folded under itself at loop end 112 as viewed in
The series presented in
As previously noted, according to the needs of the patient, system 10 can add one or more of a plurality of selectable features. For example, an extender (not illustrated) may be attached, wherein an anterior plate (not illustrated), carried in accessible pocket 98b is in one embodiment pre-drilled to facilitate acceptance thereof. An extender is a product that extends the coverage area of the brace. The extender can attach to the anterior panel via plural, e.g., four, screws to extend support up to the patient's sternal notch. System 10 can accommodate different types of extenders with different patient interfaces (e.g., pivoting, single pad, dual pads, etc.). Additionally, to enable accommodation of sizes through 5×, an extender panel (not illustrated) may be selectively incorporated.
Moreover, and beneficially, in order to facilitate progressive adaptation to patient needs, a plurality of posterior configurations are possible for use with mechanically advantaged belt 80, wherein mechanically advantaged progressive spinal system 10 includes a plurality of plates and shells 20, further described individually as posterior shells 204, 304, and 404 (plates and shells 20 referring collectively or generally to shells 204, 304 and 404), wherein use in progressive series can dynamically accommodate most courses of treatment. First posterior configuration 200 is representatively depicted' in
To facilitate utilization of posterior shell 204 with mechanically advantaged belt 80, posterior shell 204 in the illustrated embodiment is adapted with two belt retainer straps 210a, 210b. Each belt retainer strap 210a, 210b is removably installed on posterior shell 204 through upper ports 212a, 212b and lower ports 214a, 214b, respectively, and each belt retainer strap 210a, 210b can have a hook and pile fastener provided thereon. In such manner, at least one end of each belt retainer strap 210a, 210b may be unfastened from posterior shell 204, passed through one of pair of plate attachment straps 94 (
In specific embodiments, posterior shell 204 is constructed with a fourteen and one-half (14.5) inch back height, but may alternately be formed as a taller shell 20, with a back height of seventeen and one-half (17.5) inches, wherein utilization as a taller thoracolumbosacral orthosis, or taller TLSO is facilitated.

A third posterior configuration 400 is representatively depicted in
To facilitate utilization of posterior shell 404 with mechanically advantaged belt 80, posterior shell 404 like above is provided with two belt retainer straps 411a, 411b. Each belt retainer strap 411a, 411b is, like above, removably installed on posterior shell 404 (with interior padding 406 removed) through upper ports 412a, 412b and lower ports 414a, 414b, respectively. Each belt retainer strap 411a, 411b in one embodiment has hook and pile fasteners h/p provided thereon. In such manner, at least one end of each belt retainer strap 411a, 411b may be unfastened from posterior shell 404, passed through one of pair of plate attachment straps 94 (
As illustrated in
Because shell 404 is shorter than shell 304, shell 404 may be provided with only a single central strap for selectively bending the initially flat shell 404 into a shape providing for more aggressive posterior support. Similar to LSO 302, for mid-LOS 402, lordosis strap 408 may be used for adjustment of posterior shell 404. Posterior shell 404 can be a sturdy structure, but with bend accommodating regions 416a, 416b provided, wherein adjustable strap 408 may be selectively tightened to enable maintenance of a selected bend or deformation during use with posterior configuration 400. After removal of interior padding 406, adjustment of lordosis can be accomplished with posterior shell 404 lying over a table edge or the like, with lordosis strap 408 loosened. Posterior shell 404 may be bent to a selected angle or deformation, with bending accommodated at regions 416a, 416b, after which lordosis strap 408 may be tightened and re-secured, e.g., via hook and pile fastener h/p, to maintain the selected bend or deformation.
