Definitions

  • the present invention relates to a device for variable arm or shoulder positioning.
  • Such devices are used for the conservative or postoperative care of various shoulder injuries. After a shoulder injury, it is desirable to ensure the result of the operation, to avoid complications and to reduce the pain caused by muscle relaxation. A suitable position of the shoulder joint must also be ensured in order to create the basis for physiological movements.
  • the surgeon can often only determine the appropriate position of the arm in the operating room.
  • the corresponding angular position of the arm is then defined, i.e. the surgeon prescribes the optimal abduction angle (spreading angle) of the arm.
  • immobilization bandages are the TRICODOR Gilchrist bandage from Beiersdorf AG and the OMOTRAIN from Bauerfeind. Such mostly elastic bandages are close to the body and should shoulder and arm by looping around the upper body, the hip, the waist, the arm and / or fix the shoulder. They are used for the treatment of postoperative and post-traumatic indications on the shoulder and upper arm.
  • immobilization bandages proves to be uncomfortable and non-functional, since the fixation of the arm caused by them in extreme internal rotation can quickly lead to an adhesion of the axillary recess and thus to an undesirable contracture in the shoulder joint. Furthermore, immobilization of the elbow joint at a 90 ° angle can lead to severe hypertension of the biceps brachii muscle after a day or two, and accompanying sensitivity disorders in the area of the ulnar muscle. The patients complain of sensitivity disorders in the 4th and 5th fingers. Furthermore, immobilization bandages hinder adequate dressing of the patient and cause hygiene problems.
  • Known embodiments are abduction pillows from Ortho 5,dietechnik Kurtze GmbH, the DonJoy arm sling ULTRA SLING from medi Bayreuth, the inflatable medi shoulder abduction pillow SAK from medi Bayreuth and the abduction carrying wedge LÜBECK from ADEV Orthoticiandie jacket.
  • the abduction wedges or cushions are hung across a shoulder of the patient with a sling and rest on the waist or on the iliac crest on the opposite side of the patient's body.
  • the patient's forearm is attached to the wedge or pillow with loops.
  • DE-U-29717429 describes a bandage system with an abduction cushion which is divided in two in the longitudinal direction and consists of two molded body parts.
  • the shaped body parts are connected to one another via elastic bands running above and below, with spacing-changing spacers from the spacing in the intermediate spaces formed between the two shaped body parts Material of the abduction cushion for changing the abduction angle can be inserted.
  • abduction pillows are usually more comfortable for the patient than the Gilchrist bandage, they do not meet the requirements of medical professionals because they hardly take biomechanics, the function of the shoulder joint and the operative result into account.
  • DE-A-1 280 471 describes an adjustable abduction splint with a support part which can be ascertained on the left and right on the body of a wearer by tension members and on which an upper arm splint is articulated via a vertically and horizontally movable armpit.
  • the upper arm splint is fastened in a horizontally rotatable and lockable manner to a wing of a hinge which can be pivoted in the vertical plane, the other wing of which is connected to the supporting part.
  • the angle between the wings of the hinge can be determined by a strut which is adjustable in length, the ends of which are articulated on the support part or on the wing of the hinge.
  • abduction splints are ABDUKTOR, System Dr. Berrehail, from Polytech Silimed Europe GmbH, the arm abduction orthosis in modular design from Otto Bock, orthopedic industry, QUADRANT from medi Bayreuth, S.C.O.I. from medi Bayreuth and ARTROSWING from Ormed Medizintechnik.
  • the arm abduction splints are adjustable splints that are attached to the upper body with several straps and hold the arm in one position. Depending on the type and condition of the injury, the position of the rail is variable in some versions.
  • Abduction splints more or less meet the requirements of medical professionals, but take the well-being of the patient into account Patients insufficient. Abduction splints cause great discomfort to the patient when worn, which is particularly evident during the night's sleep. Furthermore, these rails can rarely be created independently. Experience has shown that the abduction splints, which are associated with high costs, are rarely or not worn by the patient.
  • the requirements for an optimal arm abduction orthosis can be divided into three groups.
  • the first group includes the physician's requirements, the second group the patient's requirements, and the third group the physiotherapist's requirements for an arm abduction orthosis.
  • the doctor requests an arm abduction orthosis with an individually adjustable arm length and with a selectable abduction angle, which can be quickly and easily put on in the recovery room immediately after the operation.
  • this ensures cost savings, since the provisional with an immobilization bandage (e.g. Gilchrist Association) is not required.
  • this ensures an enormous saving of time, because in contrast to the conventional, technically complex abduction splints, no medical technician is required to put the splints on and the doctor can easily put the orthosis on the patient himself under anesthesia.
  • the physiotherapist demands an arm abduction orthosis that can be adjusted to the current range of motion by the patient and therapist depending on the pain, the healing of the operated structures and the rehabilitation result. Furthermore, the The orthosis enables the earliest possible functional treatment, since this only requires a short treatment to restore joint mobilization. In addition, the shoulder joint should be secured when the elbow and wrist move, thus helping to reduce postoperative edema. The function of the hand should be able to be used in everyday movements, for example when eating, despite the provision of the arm orthosis.
  • an abduction cushion In order to avoid the disadvantages of the existing solutions and to better meet the described requirements for an arm abduction orthosis, the inventor first developed an abduction cushion.
  • This orthosis consists of a base cushion with an abduction angle of approx. 30 °, which can be extended to a larger abduction angle by means of an extension element.

  • the axillary wedge preferably has a dorsally raised shape.
  • it is not necessary to increase the width of the armpit wedge because on the one hand the support surface of the forearm is sufficient to increase the abduction angle and on the other hand a smaller wedge offers greater comfort.

Le dispositif selon la présente invention peut être utilisé en particulier pour le traitement conservateur ou post-opératoire de différentes lésions de l'épaule. Ledit dispositif comporte de préférence un élément distal (1), un élément proximal (2) et un coin axillaire (3) réglable en hauteur par rapport à l'élément distal (1) et / ou à l'élément proximal (2). Dans un autre mode de réalisation de la présente invention, l'élément distal peut être réglé au moins angulairement par rapport à l'élément proximal et dans un troisième mode de réalisation préféré, le coin axillaire et l'élément distal sont tous deux réglables. L'avantage du dispositif selon la présente invention est de permettre le réglage simple et variable de l'orthèse en fonction de la taille du patient et des impératifs médicaux.
