Background

Fracture conservation therapy is a well-suited treatment for simple fractures, particularly in the elderly, children, and patients with poor physical quality or resistance to surgical treatment. Common fixing means are splints, plasters, etc. Simple conservative treatment of fracture can relieve the pain of patients and reduce the economic cost, and is a good choice for patients with bone fracture. Such as: for simple distal radius fracture, 1 group of over 20000 patients with distal radius fracture in our country reported by the great book of orthopedics, Canbel orthopedics, have conservative treatment of fracture with good prognosis. The remarks are that: they have no experience with conservative treatment of such fractures.

However, conventional splints and plasters have common disadvantages, such as: the skin compression, the external fixation tightness, no external force, automatic regulation and control and no physical treatment effect are realized; moreover, functional exercise or detumescence can cause fracture displacement, and the reduction and loss cannot be dynamically controlled.

At present, the improved fixing modes at home and abroad, such as plastic plaster and polymer splints, are only different in appearance or connection mode, and cannot solve the problems in clinic.

Description of clinical problems:

and A, radius shortening deformity: the conservative treatment of distal radius fracture cannot provide axial traction force at two ends of the fracture no matter the splint is improved by any material, the contraction and deformity of the radius is easily caused by the traction of the muscle of the splint, and finally the fracture is formed to be healed by deformity

And B, healing the distal radius deformity: causing dislocation of the lower ulnar and radial joints, affecting the rotation, flexion and extension functions of the wrist joints of patients, causing residual pain, and reducing the score of the wrist joints and the satisfaction degree of the patients

More patients are contracted and displaced again after the plaster is fixed for 2 weeks, for example, the ulna head is contracted on the radial articular surface in fig. 3, and the lower ulnar dislocation is formed.

Patients with C unplanned secondary surgery with persistent chronic pain remains can cause adverse events.

The technical scheme of the invention has the following substantial technical effects and the realization process: applying multidisciplinary theoretical research, the utility model creates a new product: the external fixation device has the advantages of reliable curative effect of conservative treatment and no operation, has the effects of sliding stretching and pressurizing similar to an operation ' external bone fixation device ' (external fixator '), is internally implanted with the balloon, can dynamically expand and adjust the skin pressure, can dynamically stretch axially through magnetic force, can externally adjust and replace the wrist palm bending angle, and solves the problem of conservative treatment of fracture. In addition, static or dynamic weak magnetic field generated by matching promotes detumescence and fracture healing.

Not only can provide the magnetic force and the magnetic field of the coronal plane, but also can provide the axial stretching and pressurizing acting force through the auxiliary reduction connection and the sliding device at the far end and the near end of the fracture at the axial position. Combining with the clinical practical performance of the patient, the swelling lasts for aggravation 8-24 hours after the trauma, and the swelling obviously subsides in 3-5 days, at the moment, the plaster is replaced or the fracture is displaced and is restored again, so that the patient is suffering; the fracture position can not be adjusted through plaster without replacement, so that the 'fire fighting waterless-dry emergency' is commonly said, the reduction and the loss can not be interfered, and regret can be left. This requires the use of magnetomechanical related principles and mechanics, in combination with the medical principles described above.

The back holding portion described in the above expression is a hand back holding portion.

The more obvious the swelling is, the smaller the holding force is, and the dynamic stability is achieved.
