Description
Technical Field
The utility model relates to a steel sheet technical field is used in the fracture, particularly, relates to a hook locking of treatment shin bone outside rear side platform fracture dissects steel sheet.
Background
1. Treatment of external tibial posterior plateau fractures is a difficult point in trauma orthopedics.
2. Most of the fractures are caused by high-energy injury, and belong to intra-articular fractures. Often with collapse of the articular surface, depending on the source of treatment
The collapse exceeding 2mm necessitates surgical reduction of internal fixation, which is a relatively common method using a steel plate.
3. The principle of treating the fracture in the joint is three points:
anatomical reduction
Strong internal fixation
Early stage functional exercise
And to achieve the three principles, bone grafting is sometimes required to be structured, and in addition, the main force steel plate is required to be placed behind a tibia lateral platform for fixation.
4. The position of the operation body: in the prone position.
5. Surgical approach: a posterior approach or a posterolateral approach to the knee joint.
6. Internal fixation instrument: typically less than 5 holes, or T-shaped steel plates.
Internal fixation devices of the prior art are typically smaller than 5-hole anatomical or T-shaped plates.
Although the posterolateral approach is adopted to treat the posterolateral fracture of the tibial plateau, the tibial plateau posterolateral approach has the advantages of clear exposure of the fractured end, convenient reduction and internal fixation, relatively small trauma compared with the posteromedial approach, good clinical curative effect and the like. But the requirement for the placement of the posterolateral steel plate is also satisfied, and a short T-shaped steel plate should be selected as far as possible, because the tibialis anterior vessel bifurcation is sent from the popliteal artery 4-5cm below the highest point of the fibula, according to the literature report: the distance from the lateral platform joint surface to the position penetrating the human periosteum is 27-62mm, the distance from the tibial anterior artery to the spareribs is 17-50 mm, and the distance from the tibial anterior artery to the anterior region of the crus is limited by penetrating the periosteum, so that the extension of the posterolateral incision to the far end is limited; the possibility of blood vessel injury can be increased due to the overlong steel plate, if the fracture involves a lower metaphysis area, the branch of the tibialis anterior blood vessel must be well exposed in the operation, and a part of the periosteum is cut to increase the activity of the blood vessel if necessary, so as to ensure the safe emplacement of the distal screw. But still has a few branches of the anterior tibial artery, and the person is advised to confirm the blood vessel deformation by CT angiography (CTA) before operation. Therefore, the preoperative preparation and the intraoperative treatment are complicated.
In some cases of posterolateral fractures, the inner side of the fibula protrudes, which affects the reduction operation and the placement of the supporting steel plates, and because scar formation and anatomical structure variation occur after the first internal fixation, blood vessels and nerves are easily damaged when the internal fixation is removed, so the internal fixation is recommended not to be removed after the fracture is healed. However, it is troublesome for patients with special requirements or patients allergic to the metal of the steel plate to have to take the steel plate for treatment.
In addition, the anatomical form behind the tibial plateau is irregular, the change of a metaphysis transition area is large, the morphological structure of a posterior medial plateau and the morphological structure of a posterior lateral plateau are different, the development of a posterior plateau anatomical steel plate is difficult, the clinical popularization is not realized, the replacement of a 'T' -shaped steel plate, a clover steel plate, LC-DCP and the like at the distal end of a radius is frequently used clinically, the support and the fixation are performed after the operative shaping, but the steel plate is not a special steel plate for lower limbs, the structural strength is weak, the follow-up effect of medium and short term is satisfactory, and the follow-up effect of long term is deficient.
An effective solution to the problems in the related art has not been proposed yet.
