Description

Inner side steel sheet before shin bone distal end

Technical Field

The utility model relates to a physiotherapy instrument, in particular to a tibia far-end front inner side steel plate.

Background

Tibial pilot fractures are fractures of the distal tibial articular surface caused by vertical violence, and this complex injury is challenging to handle even for experienced trauma orthopedists. Analysis of the preoperative axial CT is important for selecting surgical access and fixation. The distal tibia at the CT axis is often divided into three major fracture blocks, a posterior lateral fracture block (Volkmann fracture block), an anterior lateral fracture block (Chaput fracture block), and a medial fracture block. Soft tissue conditions are a major factor in determining the timing of the surgery. Open reduction internal fixation is the predominant treatment for pilot fractures. The distal screw of the distal anterolateral steel plate of the tibia commonly used at present often misses or can not effectively fix the medial fracture block of the distal tibia, so that the medial low-notch steel plate or the medial column screw is necessary to fix the medial fracture block, and the steel plate screw placed in the medial minimally invasive incision can effectively support and prevent the ankle joint from inverting and malformation. The volume of the steel plate occupies a certain space, increases the difficulty of closing the wound in the stage I, and increases the medical expense. The tibia far-end anterior-medial steel plate is designed, so that the anterior-lateral bone block and the posterior-lateral bone block of the tibia far end can be effectively fixed, and the medial fracture block can be effectively fixed.

The utility model will be further described with reference to the accompanying drawings in which:

the utility model provides an inboard steel sheet before fixed shin bone pilot fracture's 3 preceding of shin bone distal end, including steel sheet body 1, steel sheet distal end 3 is provided with horizontal capable arm 11, it is crooked to the inboard that the arm 11 is gone to the side, the steel sheet is provided with locking hole 2 from near-end 4 to 3 even equidistance of distal end, steel sheet distal end 3 is provided with three locking hole 2 that are the triangular arrangement, it is provided with four locking hole 2 to go to arm 11 and keep away from 1 one end of steel sheet body, steel sheet body 1 and the arm 11 of going to go all have certain radian, make steel sheet body 1 and the arm 11 of going to go laminate with the shin bone respectively, it is 2 cross distributions to go to arm 11 and keep away from four locking holes that 1 one end of steel sheet body set up.

The working principle of the utility model is as follows:

a tibia far end 3 front inner side steel plate is designed according to the morphological data of the tibia far end 3CT of Chinese people, three locking holes 2 are designed at the far end 3 of an inner side trailing arm of the steel plate to fix an inner side tibia fracture block, a plurality of combining holes are designed at the near end 4 to be fixed on an inner side tibia bone, and screws can penetrate through outer side cortex of the tibia to be supported and fixed. The lower edge of the transverse arm 11 is close to the lower edge of the anterior cortex of the distal tibia 3, and four locking holes 2 are designed to fix a fracture block at the distal tibia 3 by anterior and posterior screws. The screw holes of the longitudinal arm and the transverse arm 11 are smoothly transited according to the anatomical morphology.

The patient is in a floating position. The posterior lateral approach of the ankle joint is reset to fix the lower fibula fracture, the posterior lateral tibial fracture block is reset simultaneously, and the kirschner wire is temporarily fixed or fixed by screws. And performing anterior-medial incision on the distal end 3 of the tibia, cutting skin, subcutaneous fascia, deep fascia and periosteum, performing periosteal stripping, lifting a shank extensor muscle group outwards, exposing a bone on the anterior side of the distal end 3 of the tibia, exposing a joint surface of the distal end 3 of the tibia in an assisting manner by a spreader, and realizing the flattening of the joint surface and the temporary fixation of a kirschner wire for fracture reduction. The gap after fracture reduction is filled with autogenous bone or allogeneic bone. C-arm fluoroscopy proves that the articular surface is dissected and reset, and the lower limb force line is good. Exposing the inner bone of the tibia, placing a front inner steel plate at the far end 3 of the tibia, adjusting the position of the steel plate, enabling the steel plate to be tightly attached to the bone, drilling by an electric drill, measuring depth, fixing by screws with corresponding lengths, fixing the steel plate on the inner bone by screws with an inner side arm, fixing an inner side fracture block by screws with the far end 3 of the inner side arm, and supporting and fixing the fracture block at the far end 3 of the tibia by the subchondral bone of a transverse arm 11. The C-arm fluoroscopy again proves that the fracture reduction is good, and the internal fixation position and the screw length are satisfactory.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
