This invention can be used for treating disease and the damage that comprises tubulose short bone and other bone section.

External device (ED) (the FR of the axial restraint of known a kind of orthopedic usefulness, A, 2559380) this device contain a kind of be parallel above the metallic rod of body, this bar is equipped with two draw point chucks, the dop of chuck utilizes spiral fastening in addition, and a chuck is installed to such an extent that can vertically move by means of thread spindle.

Above-mentioned this device can be fixed the tubular bone section, and the disconnected section of bone is vertically moved.But under the situation of the parallel storing of the fixed draw point of cantilevered, when applying load, steel skids off in bone to meeting.In addition, place the groove of draw point in the chuck and make each other at a distance of certain distance, and these grooves have determined draw point to be placed in strict given place, this situation not necessarily always allows the bone section of TA.

In treatment during bone injury, adopt a kind of disconnected section of being used for to bone section or fracture in bigger adjusting range, to carry out external shaft to fixed orthosis (GB, A, 2168255).

The central mounting that orthosis is made up of a usefulness three parts or more parts, these ingredients can be slided each other relatively by means of telescopic joint slip, but can not relatively rotate.The part of central authorities' mounting is equipped with locking device, this device can be selectively to each of mounting to the ingredient effect.

In addition, also be provided with a stressed cylinder, three members are housed on the cylinder at least, these three members can screw in mutually, and can move along common axis when rotating a member.Three members are placed in an end of cylinder, and install additional with pin, and pin may extend in the eccentric cavity of cylindrical stent.

Above-mentioned this orthosis can be adjusted relative central bracket of the member of installing with pin and the mutual configuration of member.But pin is contained in all circular holes of member each other at a certain distance, and owing to there is not possibility freely to select to settle the place of rod member in the bone section, has just determined to use inconvenience in advance.Externally in the orthosis of axial restraint, do not have possibility to adjust draw point and be placed in the interior angle of member, in addition, introduce draw point in the one side of the palm back of the body, thereby cause bending the damage of hand muscle meat.

When the damage of treatment joints of hand, but the external fixator (GB, A, 2146533) of utilization dynamometry, and this holder has two oblong bearings, the built-in positioning needle that is placed with of each bearing.Two bearings are connected with the direction hinge, and this hinge contains and is used for adjusting the distally bearing moves degree relative to the nearside bearing part.Have several circular holes on the nearside bearing, in order to put positioning needle and corresponding checknut part.The plunger of adjusting its length is arranged on the bearing in distally.The adjustment spiral that moves back and forth in the bearing groove of distally can be used to adjust the degree of stretching out of plunger.But the external fixator of dynamometry can be fixed the joint of adjacent two bones along the side surface of wrist.
