Minimally invasive tuberositas comminuted fracture back side pressurizing type fixation bone fracture plate

Abstract

The invention relates to a minimally invasive tuberositas comminuted fracture back side pressurizing type fixation bone fracture plate, which is formed by connecting a tuberositas back side fixing plate and a backbone fixing plate through a connecting plate, wherein the tuberositas back side fixing plate is in an arc-shaped curved surface structure anastomotic with the tuberositas back side surface, both ends of the tuberositas back side fixing plate are respectively provided with locking holes, locking nails penetrating through the tuberositas crown head end back side and the crown bottom end back side are respectively locked in the two locking holes, the backbone fixing plate is in a connecting plate structure anastomotic with the thighbone backbone back side surface, both ends of the backbone fixing plate are respectively provided with locking holes, and locking nails penetrating through the thighbone backbone are respectively locked in the two locking holes. When spherical nails are locked in a waist-shaped spherical groove, the direction and the angle can be adjustable, the tension of the femoral neck and the tuberositas and the tension of the broke bone of the tuberositas are respectively realized, the tuberositas comminuted fracture part is completely fixed, the spherical nails are penetrated and connected onto the backbone fixing plate in a matched way for tightly locking the thighbone backbone, the integral fixation effect is good, the accurate resetting is favorably realized, and the treatment effect is good.

Description

technical field [0001] The invention relates to the field of orthopedic medical technology, in particular to a minimally invasive trochanter comminuted fracture posterior side pressurized fixed bone plate. Background technique [0002] With the aging of my country's population and the linear increase of fractures in middle-aged and elderly people, relevant data show that the average life expectancy in China has reached 73 years, and the activity level of middle-aged and elderly people is gradually decreasing, which also leads to the incidence of osteoporosis in middle-aged and elderly people. One of the reasons for the gradual increase in the incidence rate, it has been reported in the literature that more than 90% of patients with hip (trochanteric and femoral neck) fractures are over 65 years old, and 3 / 4 of them are women. The traditional treatment method is mainly based on the dynamic hip, that is, the DHS pressurized sleeve goose-head nail. Although its therapeutic effec...

Problems solved by technology

The traditional treatment method is mainly based on the dynamic hip, that is, the DHS pressurized sleeve goose-head nail. Although its therapeutic effect has long been recognized, it is relatively complicated to install clinically and causes too much damage to the skeleton. The femoral neck and the ball head fixation part It is a tension nail, relatively poor in stability, and there are many product breakages in clinical applications; the tension nail only produces tension after installation, and it is difficult to achieve correct reduction during surgery, and the contact between the bone plate and the bone surface is too large. less, resulting in incorrect reset, unstable fixation, and poor therapeutic effect; the diameter of the head sleeve of the DHS sleeve goose-head nail is 13mm, and the length is 25-30mm. The goose-head nail sleeve basically blocks the medullary cavity between the trochanters, preventing the circulation of blood and bone marrow in the medullary cavity, which also affects the re-growth speed of the fracture, prolongs the healing time, and increases the pain of the patient
