Definitions

  • the present invention falls within the field of orthopedic devices. More specifically, the invention refers to a semi-rigid splint in the form of a bracelet used for the treatment or prevention of carpal tunnel syndrome and related conditions by modifying the morphology of the carpal tunnel.
  • the hand is made up of different bones, muscles, and ligaments that allow for a large number of movements. With respect to the bones of the hand, humans have a total of twenty-seven, of which eight constitute the wrist. These eight bones, known as the carpal bones, are arranged in two rows, the bones in each row being tightly knit.
  • the proximal row is composed of the scaphoid, lunate, triquetrum, and pisiform bones, while the distal row comprises the trapezium, trapezoid, capitate, and hamate bones.
  • the scaphoid, lunate, and part of the triquetrum articulate with the distal end of the radius to form the radiocarpal joint.
  • the distal surface of the proximal row forms a deep concave notch into which the bones of the distal row fit, forming the midcarpal joint.
  • the anatomical space formed by the carpal bones and the annular or transverse carpal ligament is called the carpal tunnel.
  • the carpal tunnel Through the interior of this tunnel pass: the tendons of the superficial and deep flexor muscles of the fingers, the tendon of the long flexor muscle of the thumb, and the median nerve.
  • Carpal tunnel syndrome is usually caused by increased pressure on the median nerve.
  • the median nerve When the median nerve is compressed, it usually causes pain, numbness, tingling, and/or weakness in the hand and forearm.
  • the morphology of the hand and wrist, as well as possible repetitive movements of the hand, can contribute to the development of this syndrome.
  • Treatment of carpal tunnel syndrome aims to reduce pressure on the median nerve and prevent irreversible nerve damage over time.
  • Non-pharmacological treatments for mild or moderate cases of this syndrome include the use of orthopedic devices that maintain the position of the wrist, cause stretching of the transverse carpal ligament, or modify the shape of the carpal tunnel.
  • Orthopedic devices that maintain wrist position are the most commonly used for carpal tunnel treatment. They are passive splints that only maintain the position of the wrist joint. They are usually placed mainly on the ventral side of the forearm, wrist and hand. They are usually made of rigid material (such as, for example, the devices disclosed in patents US6106492A, US5769804A, US6383157B1), semi-rigid (see, for example, US20040176714A1, US5766141A, US7081102B1) or flexible (see, for example, US4883073A, US50 US1B6515 , US6213969B1). These devices do not cause a modification of the carpal tunnel space and neither do they modify the compressive forces that are produced on the median nerve. In addition, many of them cause unwanted anterior compression of the carpal tunnel.
  • the third type of devices used for the treatment of carpal tunnel syndrome are semi-rigid or soft splints that modify the shape of the carpal tunnel, increasing its space. These devices mainly perform the corrective forces on the bones of the forearm; that is, without a direct effect on the carpal bones (see, for example, US4966137A, US5385537A, US6120472A, US5413553A), affecting the functional capacity of the upper extremity of the user and, consequently, the normal development of their daily activity . In addition, they do not prevent compression on the ventral or anterior part. of the carpal tunnel, do not control the position of the wrist and/or do not conform to the carpal bones of the distal row (see, for example, US5478306A, US5921949A).
  • the present invention proposes a solution to the aforementioned limitations, by means of a novel three-dimensional orthopedic device that has improved efficacy compared to known devices.
  • the object of the present invention relates to a three-dimensional orthopedic device for the treatment of carpal tunnel syndrome and related conditions by increasing circularity and the antero-posterior diameter of the carpal tunnel, without causing compression of said anatomical space and without affecting the functional capacity of the user's upper extremity.
