Minimally invasive treatment proximal femur comminuted fracture inside and outside marrow united fixing system

Abstract

The invention discloses a minimally invasive treatment proximal femur comminuted fracture inside and outside marrow united fixing system. According to the minimally invasive treatment proximal femur comminuted fracture inside and outside marrow united fixing system disclosed by the invention, pins are placed in a minimally invasive manner through guiding sleeves, and all the guiding sleeves correspond to intramedullary pins and a proximal femur fixing plate, so that the purpose of treating without splitting the fracture position is achieved; and proximal femur comminuted fracture is treated bythe minimally invasive treatment proximal femur comminuted fracture inside and outside marrow united fixing system, minimally invasive treatment proximal femur comminuted fracture inside and outsidemarrow united fixing system is simple to operate, small in incision, good in integral fixing effect, reliable in tensioning, free from loosening, free from potential safety hazard after being used fora long term, favorable for accurate restoration , free from deformation, and good in treatment effects.

Description

technical field [0001] The invention belongs to the field of orthopedic medical technology, and in particular relates to a combined extramedullary and intramedullary fixation system for minimally invasive treatment of comminuted proximal femur fractures. 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, there are reports in the literature that more than 90% of patients with hip (intertrochanteric 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 sle...

AI Technical Summary

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
