Description

Hallux valgus orthopedic fixing device

Technical Field

The utility model relates to the technical field of limb correction, in particular to a hallux valgus correction fixing device.

Background

Hallux valgus is a very common hallux deformity, which is a three-dimensional deformity with the hallux pronated on the coronal plane; hallux valgus in cross section; while the hallux is dorsally stretched in the sagittal plane.

Initially, hallux valgus deformity was primarily a conservative treatment. The treatment of children and teenagers is to wear specially made orthopedic shoes while constantly training the muscles of the arch. And in adults, the adult is fixed by a special orthopedic device. For very serious deformities, the deformity needs to be corrected by Kramer osteotomy or Chevron osteotomy, the stability is lacked when the angle between metatarsals exceeds 14 degrees, the foot is stressed by external fixing of a brace or wearing orthopedic shoes after the operation, the postoperative care is complicated, and the rest is needed for 6-8 weeks, so that many patients are difficult to receive the operation treatment.

SUMMERY OF THE UTILITY MODEL

In order to solve the prior art problem, the utility model provides a hallux valgus orthopedic fixing device. The fixing device includes: an orthopedic plate;

one end of the orthopedic plate is detachably connected with a fixed rod, and the fixed rod and the orthopedic plate are arranged at an angle.

Furthermore, the orthopedic plate is a Z-shaped plate, and the fixing rod is perpendicular to the orthopedic plate.

Furthermore, one end of the orthopedic plate is provided with a connecting hole, and one end of the fixing rod is fixed in the metatarsal bone through the connecting hole.

Further, the fixing rod is a screw.

Furthermore, wave-shaped bulges are arranged on two opposite sides of one end of the orthopedic plate, which is positioned in the metatarsal bone marrow cavity.

The utility model provides a technical scheme's beneficial effect is: the utility model discloses in, be provided with the orthopedic plate, the one end of orthopedic plate can be dismantled and be connected with the dead lever, inserts the bone marrow intracavity of metatarsus with the one end of orthopedic plate, and the other end passes through the dead lever and fixes the one end at the metatarsal to can offset heavy burden, and eliminated the distortion power between the osteotomy, guaranteed the stability between the osteotomy face effectively like this, can make its repairing process go on in stable environment, until healing completely, patient's rehabilitation time has shortened half than other methods, it is painful to reduce patient.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1-4, a hallux valgus orthopedic fixation device comprising: an orthopedic plate 1; the orthopedic plate 1 is a Z-shaped plate, a connecting hole 3 is formed in one end of the orthopedic plate 1, a fixing rod 2 is connected in the connecting hole 3, the fixing rod 2 is perpendicular to the orthopedic plate 1, one end of the fixing rod 2 is fixed to one end of the metatarsal bone through the connecting hole 3, the end portion, far away from the connecting hole 3, of the orthopedic plate 1 is fixed in a medullary cavity of the other end of the metatarsal bone, and wavy line protrusions 4 are arranged on two opposite sides of the end portion. The fixing rod 2 can be a screw, the diameter of the thread is 4mm, and the length of the screw with the diameter of 1.8mm can be 20, 22, 24, 26 and 28 mm.

This use neotype complete work flow can be: stoffella's Chevron osteotomy, Stoffella's Chevron osteotomy line is 90-120 degrees from distal metatarsal, note: firstly, cutting bones outside a joint capsule; the second is to maintain two points of bony contact with the metatarsal heads during maximum lateral movement of the metatarsal bones. After osteotomy, adduction, plantarflexion and dorsiflexion of the broken ends are allowed, the metatarsal heads are moved outwards and measured by a special tool, the position is kept by a bone holder after eversion and pronation correction, the depth of the metatarsal medullary cavity is measured to select a proper orthopedic plate 1, and finally the end part of the orthopedic plate 1 provided with the wavy line bulge 4 is inserted into the metatarsal medullary cavity and is forcibly inserted, so that the metatarsal heads can be contacted by several millimeters when bearing weight. The depth of the metatarsal medullary cavity is measured by a measuring scale, if the metatarsal medullary cavity is too long, the metatarsal medullary cavity can be cut off, the other end of the orthopedic plate 1 pushes the metatarsal head to the outside, the fixing rod 2 is inserted into the connecting hole 3 and screwed into the metatarsal head, the fixing rod 2 enables the metatarsal head to have continuous outward pushing force, and therefore severe hallux valgus can be treated, even if the angle between the three-bristle cudrania bones exceeds 24 degrees, the metatarsal head can be taken out for internal fixation after 5 weeks of operation.

By using the fixing device, the thumb valgus correction angle is averagely 18 degrees and the correction angle between metatarsals is 9 degrees through the follow-up diagnosis of an average 20 months of 72 feet. The pain of 47% of patients before operation is different in degree when wearing shoes, and the pain of 96% of patients after operation is relieved. The sneakers can be worn by 50% of patients 2 weeks after surgery, half of the patients start to work again 2 weeks after surgery, and 75% of the patients work again 4 weeks later.

It is worth explaining, in the utility model, be provided with the orthopedic plate, the one end of orthopedic plate can be dismantled and be connected with the dead lever, with the one end of orthopedic plate insert the metatarsal bone marrow intracavity, the other end passes through the dead lever to be fixed in the one end of metatarsal, thereby can offset heavy burden, and eliminated the distortion power between the osteotomy, guaranteed the stability between the osteotomy face like this effectively, can make its repair process go on in stable environment, until the fracture completely heals, patient's rehabilitation time has shortened half than other methods, it is painful to reduce patient.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
