Definitions

  • the present invention relates to braces for use in scoliosis therapy.
  • the present invention relates to the application of improved bracing to heal or assist in healing the scoliotic spinal curve of a patient having scoliosis.
  • braces are not adjustable, users have the same treatment whether asleep, when more aggressive treatment is possible, and awake, when more aggressive treatment is very painful.
  • the present invention teaches a method and apparatus for dynamic scoliosis orthosis. More particularly, the present invention teaches an apparatus for improving scoliosis treatment and therapy, as well as a method for making a brace and using a brace in treating patients with scoliosis.
  • Figure 1 is an isometric view of a first embodiment of the dynamic scoliosis orthosis (brace);
  • Figure 2 is an orthographic rear view of a first embodiment of the dynamic scoliosis orthosis (brace);
  • Figure 3 is a close-up view of the apical pad portion of figure 2 with the adjustment key shown removed from the brace, and;
  • Figure 4 is a substantially orthographic cross-sectional view of the rod portion of the brace taken at the location indicated by the section arrows in figure 2.
  • FIGS 1 through 4 illustrate an exemplary embodiment of a Dynamic Scoliosis Orthosis or brace (or harness) 10.
  • Brace 10 comprises a rod 15, a pelvic mold 30, an auxiliary pad 40, an apical pad 45, an extension arm 50, and an adjustment key 75.
  • Rod 15 may be made of a variety of materials or composite of materials including metals such as aluminum, carbon fiber, polymers or fibers and resins. Ideally the material selected will provide a rigid and stable support for the harness, thus providing steady force on the curved spine.
  • the exemplary embodiment of the invention teaches a carbon fiber rod because it is light weight, flexible and still extremely strong.
  • Rod 15 has a general elliptical cross-sectional shape so as to minimize the distance that rod 15 protrudes outwardly from the user's back, and so as to provide a greater resistance to bending in a lateral or side-to-side direction than in a fore-aft direction. Such difference in the resistance to bending provides for increased flexure mobility of the user of brace 10 and yet allows brace 10 to provide substantial scoliotic correctional loading to the spine of the user of brace 10.
  • the rod may be curved or straight, depending on what is best for the patient.
  • the rod further comprises a first (upper) end 20 and a second (lower) end 25.
  • the present invention further teaches treating a double curved spine by enlarging the pelvic mold so as to extend further up the user's body.
  • First end 20 is coupled to pelvic mold 30 which contacts the user or wearer of brace 10 below the scoliosis curve of the user.
  • Pelvic mold 30 is preferably custom fit for each wearer, and is formed from rigid polymers such as polypropylene. The custom fit of pelvic mold 30 maximizes the effectiveness of rod 15 by providing a tight and secure anchor for rod 15.
  • pelvic mold 30 may also be generically sized, and customized to fit snugly to the patient with inserts (not shown.) Inserts may also be used to improve the ease with which the present invention is cleaned.
  • pelvic mold 30 has a fastener 35 to aid the wearer in donning and removing the brace 10.
  • the fastener 35 may be a belt and buckle, hook and loop, or a friction mechanism.
  • Auxiliary pad 40 is coupled to second end 20 of rod 15 and contacts the user or wearer's body above the scoliosis curve of the user. Generally, auxiliary pad 40 is
  • Auxiliary pad 40 is preferably formed from a rigid polymer, a metal, or a composite, selecting the materials best suited for the patient's need.
  • Auxiliary pad 40 can be permanently coupled to the rod 15 using an epoxy, a mechanical mechanism or any other means known in the art.
  • auxiliary pad 40 When permanently attached to rod 15, auxiliary pad 40 preferably includes a removable and replaceable cover to improve the ease with which the pad is cleaned, replaced, or customized.
  • auxiliary pad 40 may also be releasably coupled to rod 15 via a tab and sleeve configuration, or a non-permanent mechanical means known in the art. It is noted that auxiliary pad 40 may be replaced as the patient grows, or as the pad is worn out.
  • Extension arm 50 preferably includes an adjustment mechanism 55, adjustable mount bracket 57, guides 60, and an adjustment key 75.
  • Extension arm 50 is adjustably coupled to the rod 15 between the ends 20 and 25 of rod 15 by means of adjustable bracket 57.
  • Apical pad 45 is extendably and retractably coupled to extension arm 50.
  • Apical pad 45 is similar in form and structure to auxiliary pad 40, but is positioned to create a counter force to auxiliary pad 40 on the user's spine over the apex of the curvature of the user's spine.
  • a load is applied that is a counter load to the load applied by auxiliary pad 40 and pelvic mold 30.
  • the amount of load exerted by apical pad 45 is adjustable via adjustment mechanism 55.
  • Adjustment mechanism 55 may be any of a rack and pinion gear, a sliding lock, a toothed track secured by screws, or any other mechanism commonly known in the art.
  • Removable adjustment key 75 engages into adjustment mechanism 55 and rotationally operates to adjust adjustment mechanism 55.
  • a knob or like adjust device may be integrally built into adjustment mechanism 55 to operatively adjust apical pad 45.
  • Adjustment mechanism 55 allows the user to increase the corrective load apical pad 45 exerts on the apex of the spine of the user to decrease the term of treatment of the user. Increasing the load is a common practice for patients, especially at night when the load can be greatly increased without severe discomfort to the user. Adjustment mechanism 55 is adjusted within guides 60 and according to setting marks 65 and 70.
  • Setting mark 65 preferably corresponds to a night time tension adjustment setting and setting mark 70 preferably corresponds to a day time tension adjustment setting.
  • Setting marks 65 and 70 are preferably placed on apical pad 45 by a physician and are placed to maximize the effectiveness of the treatment.
  • the invention also teaches adjusting the setting to minimize the pain caused by the treatment.

  • extension arm 50 may be coupled to rod 15 either permanently or non-permanently by selectively using means coupling means known in the art.
  • extension arm 50 may be adjustable on rod 15 so as to provide multiple fixation points on rod 15, thus allowing for periodic adaptation or fit of the user as the user grows. Such adaptation greatly reduces the cost of treatment by avoiding the need for the user to purchase multiple braces over time as the user grows.
  • brace 10 has only three contact points, it has an open design, thus maximizing the freedom of motion of the user of the brace.
  • the three- contact-points also minimize the amount of contact between the brace and the user, thus brace 10 is cooler and spares sensitive skin from excessive contact.
  • the "three contact points" refer to the three principal load applying contact points.
  • the first principal load applied in a first substantially lateral direction by auxiliary pad 40 is applied at a first contact point.
  • the second principal load applied in a second substantially lateral direction (substantially opposing the first lateral direction) by apical pad 45 is applied at a second contact point.
  • the third principal load applied in the first substantially lateral direction (substantially opposing the second lateral direction) by pelvic mold 30 is applied at a third contact point.
  • Any other loads and load points associated with brace 10 are substantially incidental to the described scoliosis correcting principal loads and principal load points.
  • the amount of surface area contact of the torso of the body of the user of brace 10, the torso being understood to have an upper boundary of the user's neck and a lower boundary of the user's waist, divided by the total surface area of the torso of the body of the user of brace 10, shall be understood to be a brace to torso contact ratio.
  • the brace to torso contact ratio is no more than 60%. In alternative embodiments, the brace to torso contact ratio is no more than 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 5% and 3% respectively. Furthermore, the minimal nature of the invention reduces any embarrassment the user may feel because brace 10 can be concealed beneath clothing. Finally, the three-contact-points allow the wearer to breathe normally, without restricting chest expansion.
  • the elliptical cross-section of rod 15 functions to maximize the user's freedom of movement by allowing the user to bend forward and backward while still providing a load on the apex of the curve of the spine of the user.
  • Brace 10 thus allows the wearer flexion and extension movements.
  • brace 10 The modular design of brace 10 allows parts of brace 10 to be replaced and exchanged without having to replace the entirety of brace 10.
  • Brace 10 may be fitted to treat either a right or left curved spine.
  • Benefits of the dynamic scoliosis orthosis (DSO) invention include: an adjustable tension loading that allows for individualized settings for different user tolerance and for periods of low force if there is pressure sensitive skin, respiratory distress, etc., an open design that is lighter than standard thorico lubo sacral orthosis
  • brace 10 is primarily intended for the correction of single scoliotic curves. However, especially with the addition of an enlarged pelvic girdle, double curves (extending pelvic high) could also be treated.
