Definitions

  • the invention relates to a device and a method for measuring the position of a first part to another part of a joint in a human or animal body.
  • Such devices are known in the field of signal generators for computer games. For example, gloves with sensors are used to convey the movement of a hand to a controller. Depending on the quality of the device, even minimal movements of a joint are detected, analyzed and reported to a control device. Such devices have a wide range of applications and the continuous improvement of the sensors enables a virtually error-free imaging of the movement of a human or animal body in a computer program.
  • the invention is based on the finding that the selected transmission of a signal opens up completely new fields of application of such devices only in the case of a defined position of a musculoskeletal system.
  • a defined position of a musculoskeletal system For example, in the sporting field overuse of a joint can be prevented by early attention is drawn to a malposition.
  • the device allows the device to avoid misalignments, especially after surgery.
  • a special field of application opens up when the misalignment is a dislocation.
  • a dislocation is, for example, a dislocation with loss of contact of the socket and the head-carrying shaft. Such dislocations occur, for example, after total hip replacement and endanger the success of artificial joint replacement as a very painful complication. Dislocations can lead to illness, prolonged hospitalization and reoperation. They cause a not inconsiderable increase in the cost of treatment.
  • Dislocation is the leading cause of second surgeries in patients over the age of 70 years. In some studies, the dislocation rate is fifty percent. The prevention of dislocation is therefore a great challenge for patients and is of great importance for orthopedic surgeons and not least for health care providers.
  • the invention therefore relates above all to devices in which the first part is an artificial joint part, in particular a joint ball, and the second part is an artificial joint part and in particular a joint socket.
  • a movement limit that permits misalignment is a flexion of more than 90 degrees, a rotational movement of the thigh over 45 degrees (internal / external rotation) or an extension (abduction) as well as an extension in the hip joint .
  • Normal movement sequences are thus not affected by the device and only when a previously defined movement limit value is exceeded, a signal is triggered in order to avoid a malposition.
  • the device according to the invention thus allows uncomplicated movements of daily life, and only for specific movements of the joint, a signal is triggered before reaching a malposition, which prevents a person or possibly also an animal from continuing the movement in this direction of movement.
  • the device thus constitutes a contemporary simple and effective strategy for minimizing risk of dislocation after endoprosthesis implantation, which does justice to the active early postoperative limitation of the range of motion in the operated hip joint on the one hand, and the related demands on the patients on the other hand. It helps in the early phase after surgery to avoid dislocation-inducing movements and also to learn and maintain safe behaviors in everyday life.
  • the device preferably has a sensor which detects the position from the distance of a point on the first part to a point - A - the second part determined.
  • This sensor can be arranged in an artificial hip joint and for determining the position of the distance fixed points on the socket and ball joint and / or rotation between these parts can be measured to each other.
  • the device has a plurality of sensors that detect the position. As a result, flexion, extension, abduction and external and internal rotation can be determined.
  • the sensors are generally intended to record the position and movement of joint-defined reference points within a coordinate system in space and to provide corresponding data about the joint position.
  • sensors in the form of strips or punctiform but also be mounted as flat plates on the body, for example, over an artificial hip joint.
  • At least one sensor is a strain gauge.
  • strain gauges are arranged crossing each other.
  • a simple embodiment provides that sensors are arranged on a textile fabric. For example, their integration on or in clothing is conceivable. A placement of the sensors in an endoprosthesis itself is possible. Especially for patients after hip joint surgery, it is advantageous if the sensors are attached to a pair of pants. Accordingly, the sensors can be arranged for example for shoulder injuries in a shirt or jacket.
  • the sensors can be measured by impedance measurement (inductance capacitance measurement), resistance measurement, induction measurement and Phase shift work. As movement limit values, diffraction, extension, rotation, abduction, spread and force, negative and positive accelerations can be determined.
  • the measurement is carried out accordingly with goniometers, strain gauges, inclinometers, pressure sensors, ac- celerometers or force sensors.
  • goniometers bridging an articular joint can measure the angle of the joint position of an endoprosthesis in different planes.
  • strain gauges positioned above and next to a joint can provide further data about movements of a joint or, in particular, of an artificial joint replacement via their change in length.
  • a special embodiment provides that at least one sensor is arranged on a part of the joint.
  • sensors act on a signal generator via an analyzer.
  • the signal is preferably an optical or acoustic signal.
  • vibration can also serve as the preferred signal.
  • a signal generator is attached to a textile. This leads for example to a pair of pants with sensors, analyzer and signal generator, which avoids malpositions of a musculoskeletal system as an easy-to-wear textile.
  • the invention is solved by a method for measuring the position of a first part to another part of a joint in a human or animal body in which a signal is triggered only when a movement limit value permitting misalignment is exceeded.
  • a preferred use of the device according to the invention is the use for avoiding dislocations, in particular in the medical field.

  • On the plug head 4 is a first part 6 of a sensor 7, which cooperates with a further part 8 of this sensor. The sensor can thereby measure the distance between the parts 6 and 8 or a relative rotation of the plug head to the pan inlay.
  • the prosthesis head 4 If certain movement limit values are exceeded, the prosthesis head 4, as shown in the schematic X-ray image shown in FIG. 2, can pop out of the cup inlay 3, resulting in an unacceptable dislocation. [26] To avoid this, the sensor 7 measures the relative position between the prosthetic head and the cup inlay and reports corresponding values to an analyzer that triggers an alarm system when a limit value is exceeded.
