Definitions

  • the present invention relates to a wrist splint, in particular to a wrist splint for the prevention or the treatment of carpal tunnel syndrome.
  • a commonly used type of wrist splints the so-called carpal tunnel orthosis, which is described, for example, in the document EP 0916325 A1.
  • the so-called carpal tunnel syndrome (CTS) occurs due to nerve entrapment in the wrist area to tingling, numbness and pain of the thumb, the index finger and the middle finger of the affected hand.
  • CTS carpal tunnel syndrome
  • One possible therapy to treat CTS is the immobilization of the wrist with a special splint, a so-called carpal tunnel orthosis as it is described, for example, in the document EP 0916325 A1.
  • Such splints or orthoses are fixed by means of flexible straps around the forearm and the hand.
  • Such straps may include rigid pre-bent or bendable straps, and/or fasteners comprising plastic and/or metal inserts, and/or straps made from a textile material which can be usually secured by means of Velcro (hook and loop) fasteners.
  • the above document EP 0916325 A1 discloses an orthesis for and/or treatment of carpal tunnel syndrome, comprising a substantially rigid hand fixation brace extending immediately over the dorsal part of the hand, which brace has two ends, one of which is provided with a part to be fastened to the wrist and underarm while the other is provided with a finger coupling part.
  • the document DE 43 26 751 A1 discloses a hand and wrist orthosis that comprises a supporting body enclosing the wrist joint and the hand in a sleeve-like fashion, and a spoon- shaped rigid splint disposed on the inner wall area of the supporting body, which supports the hollow hand and makes it possible for the tip of the fingers to grip, wherein within the region of the phalanges and the metacarpal bones, the splint has three splint sections bent at predetermined angular positions relative to each other.
  • the document US 6,328,706 discloses a wrist support device for allowing limited extension and flexion of the wrist, while substantially limiting movement of the wrist in all other directions and further substantially limiting pressure from being placed on the wrist.
  • This wrist support device includes a first elongated channel-shaped rigid member for aligning with the longitudinal axis of the user's forearm for abutting against the posterior aspect of the forearm and a second small rigid substantially flat member independent from the first member for aligning with the longitudinal axis of the user's forearm and abutting against the anterior aspect of the forearm.
  • the two members are attached together and secured to the user's forearm by a plurality of releasable fastening members, such that when tightened, the wrist support device limits extension and flexion of the wrist and substantially limits pressure being placed on the wrist.
  • the main drawback of this wrist support device is that the rigid supporting member cannot be precisely fitted to the shape of the hand, while the inner cushioning layer beneath the rigid supporting member still allows some movement of the wrist. Neither this device provides enough support for the palm against the movement of the wrist downwards.
  • the wrist splints known in prior art are very complicated in terms of structure, or have a highly simplified construction that leads to an insufficient immobilization of the wrist, or have a configuration that is uncomfortable to wear.
  • a first elongated splint portion formed to substantially fit to a patient's forearm and hand in the region of the ulna and the metacarpal bone of the little finger;
  • a second elongate splint portion formed to substantially fit to a patient's forearm and hand in the region of the radius and the metacarpal bone of the indexing finger;
  • interconnecting members between the first and second elongate splint portions, the interconnecting members being formed to substantially fit to the dorsal side of the forearm or the hand;
  • splint body is made of a substantially rigid but permanently deformable material.
  • the splint body may be made of a longitudinally corrugated thin metal, for example, aluminium, plate or a thermoplastic material.
  • the splint body comprises a plurality of through-holes uniformly distributed over its entire area.
  • the splint body is formed as a multilayer structure of a substantially rigid but permanently deformable splint core, a first covering layer on one face of the splint core and a second covering layer on the opposite face of the splint core, said covering layers being made from an elastic material.
  • the splint core may comprise a plurality of through- holes uniformly distributed over its entire area, and the first and second covering layers may also comprise a plurality of through-holes in alignment with the through-holes of the splint core.
  • each of the at least one fastening member comprises Velcro fasteners at least at its ends.
  • the first covering layer may be made of a Velcro- compatible material and adapted for attaching to the Velcro fasteners of a fastening member of the wrist splint.
  • a wrist splint body comprising
  • first elongated splint portion dimensioned and shaped to be capable of partially covering, upon its bending, a patient's forearm and hand in the region of the ulna and the metacarpal bone of the little finger;
  • a second elongate splint portion spaced apart from the first splint portion and extending slightly inclined with respect to said first splint portion, said second splint portion being dimensioned and shaped to be capable of partially covering, upon its bending, a patient's forearm and hand in the region of the radius and the metacarpal bone of the indexing finger;
  • interconnecting members between the first and second elongate splint portions, the interconnecting members being shaped to be capable of substantially fitting, upon its bending, to the dorsal side of the forearm or the hand of a patient;
  • splint body is made of a substantially rigid, permanently deformable material.
  • the wrist splint body may be made of a longitudinally corrugated metal, for example, aluminium, plate or a thermoplastic material.
  • the wrist splint body may further comprise a plurality of through-holes uniformly distributed over its entire area.
  • the wrist splint body is formed as a multilayer structure of a substantially rigid but permanently deformable splint core, a first covering layer on one face of the splint core and a second covering layer on the opposite face of the splint core, said covering layers being made from an elastic material.
  • the wrist splint body may further comprise a plurality of through-holes uniformly distributed over its entire area.
  • Figures 1a and 1 b show the splint body of a preferred embodiment of the wrist splint according to the invention in a flattened state, in plan view and in cross-sectional view taken along the line B-B shown in Fig. 1a, respectively;
  • FIG. 2 is a top perspective view of a preferred embodiment of the wrist splint according to the invention when applied on a patient's wrist;
  • Figure 3 is a bottom perspective view of the same wrist splint as shown in Fig. 2;
  • Figure 4 is a plan view of a flattened splint body of the wrist splint according to the invention.
  • Figure 5 is a perspective view of a preferred embodiment of the wrist splint according to the invention in a spatially formed, ready-to-use state.
  • a wrist splint 10 to substantially prevent movement (i.e. to immobilize) of the wrist in any direction.
  • the wrist splint 10 comprises a splint body 11 , which in its initial state (i.e. in a state before its bending to form a splint body ready for use) is shown in Fig. 4.
  • the splint body 1 1 comprises a first elongated splint portion 14 dimensioned and shaped to be capable of partially covering, upon its bending, a patient's forearm and hand in the region of the ulna and the metacarpal bone of the little finger, and a second elongate splint portion 15 spaced apart from the first splint portion 14 and extending slightly inclined with respect to said first splint portion 14.
  • the second elongate splint portion 15 is dimensioned and shaped to be capable of partially covering, upon its bending, a patient's forearm and hand in the region of the radius and the metacarpal bone of the indexing finger.
  • interconnecting members 16, 17 between the first and second elongate splint portions 14, 15, which are integrally connected to the first and second splint portions 14, 15 at different locations along the splint portions 14, 15, wherein the interconnecting members 16, 17 are shaped to be capable of substantially fitting, upon its bending, to the dorsal side of the forearm or the hand of a patient.
  • an aperture 13 is defined by the splint portions 14, 15 and the interconnection members 16, 17. It is obvious for a skilled person that in case more than two interconnection members are used to interconnect the first and second elongate splint portions, more than one apertures are defined in the splint body.
  • a laterally projecting tab 12 is formed as an integral part of the first splint portion 14 at its front end. This tab 12 is dimensioned and shaped to be capable of substantially surrounding, upon its bending, a patient's hand in the region of the hypothenar.
  • the wrist splint 10 has a longitudinal splint direction 34, which is aligned substantially parallel to the longitudinal direction of the forearm when the splint is in use.
  • Figures 1 a and 1 b illustrate another preferred embodiment of the splint body of the wrist splint according to the invention.
  • the splint body 1 1 comprises a plurality of through-holes 18 uniformly distributed over its entire area as illustrated in Figure 1 a.
  • the splint body 11 is formed as a multilayer structure consisting of a splint core 20, a first (or outer) covering layer 21 on its outer surface, and a second (or inner) covering layer 19 on its opposite (i.e. inner) surface facing toward the skin of the patient.
  • the splint core 20 is made of a substantially rigid but permanently deformable thin plate to provide the supporting function for the splint body.
  • the covering layers 19, 21 are preferably made from an elastic material so that they can adapt their shapes and dimensions to the bended (or otherwise spatially formed) splint core 20.
  • the outer covering layer 21 may, for example, be made of a foamed, preferably washable material.
  • the inner covering layer 19 may be formed, for example, as a skin- compatible fabric or the like. However, other materials for the covering layers 19, 21 may also be readily conceivable.
  • the covering layers 19, 21 and the splint core 20 each contain through-holes on their entire area in a uniformly distributed manner, wherein the through-holes of the covering layers 19, 21 are in alignment with the through-holes of the splint core 20, together forming the through-holes 18 of the entire splint body 11.
  • the through-holes and the covering layers may be applied independently of each other, i.e. there may be an embodiment of the splint body which comprises a plurality of through-holes, but is not provided with covering layers, and it is also conceivable that in an alternative multilayer embodiment of the splint body, there are no through-holes formed on the splint core, (i.e. the splint core has a plain surface), while the splint core is covered by inner and outer covering layers (which do not contain through-holes either).
  • the splint body 11 (or the splint core 20 in a multilayer configuration of the splint body) is made of a substantially rigid but permanently deformable material.
  • the splint body 1 1 (or the splint core 20) may be made of a longitudinally corrugated thin metal plate, preferably aluminium plate.
  • the corrugated metal plate has a thickness of preferably 0,2-1 mm, more preferably about 0,6 mm.
  • the splint body 11 (or the splint core 20) may equally be made of a thermoplastic material, which may be fitted to the shape of the wrist in a heated state, and after cooling it provides a dimensionally stable splint for the wrist. It should be note that any other materials may readily be used for the splint body (or splint core) that have self- supporting property and suitable for permanent deformation in any way, in particular by hand.
  • FIGs 2 and 3 are top and bottom perspective views, respectively, of a preferred embodiment of the wrist splint according to the invention when applied on a patient's wrist, whereas Fig. 5 depicts the same wrist splint in a spatially formed, ready-to-use state in a perspective view.
  • the wrist splint 10 of the invention will now be further described with reference to Figures 2, 3 and 5.
  • the wrist splint 10 comprises a splint body 11 as described above and at least one bendable, non-stretchable and releasable fastening member for securing the splint body 1 1 to a patient's forearm 22 and hand 23.
  • a first fastening member 30 is arranged at the rear end 51 of the splint 10
  • a second fastening member 31 is arranged approximately at the middle of the splint 1 1 (preferably in the region of the wrist)

It is noted that although the splint body of the wrist splint according to the invention substantially fits to the shape of the forearm and the hand of most patients, some additional subsequent adjustments of the shape of the splint body (e.g.
  • the at least one fastening member is used to firmly secure the splint body to the forearm and the hand thereby preventing movement of the wrist in any direction.
  • the orientation of the second splint portion 15 is ideal since, as depicted by the dot and dash- line in FIG. 2, the radius 33 is "extended” and is substantially “connected” with the metacarpal bone of the middle finger 27 by means of the second elongation splint portion 15 of the splint 10.
  • the outwardly projecting lateral tab 12 which preferably has an arcuate outer edge, substantially covers the hypothenar region adjacent to the little finger 29, thereby strongly supporting the of the inner side of the palm 24 and preventing the wrist from moving downwards.
  • the wrist is optimally fixed relative to the forearm 22 without restricting the mobility of the thumb 25 and the other fingers, i.e. index finger 26, middle finger 27, ring finger 28 and pinky finger 29 in any way.
  • the splint 10 forms a stable immobilization device that prevents the movement of the wrist in all direction.
