Pressurizing anatomical bone fracture plate for symphysis pubis orthopedic

Abstract

The invention provides a pressurizing anatomical bone fracture plate for symphysis pubis orthopedic. The pressurizing anatomical bone fracture plate comprises a main body plate and two front wing plates; the main body plate comprises a middle plate and side wing plates located on the two sides of the middle plate, the bottom face of the middle plate is in the anatomic form of pubis and pubis union so as to be attached to the inner side of the pubis and pubis union, and the side wing plates extend from the two sides of the middle plate so as to be connected to the upper part of the pubic ramus; and the front wing plates are connected to the outer side of the middle plate, the two front wing plates are used for being correspondingly connected to pubis on the left side and the right side of the symphysis pubis, and the bottom faces of the front wing plates are in the anatomic form above the pubic ramus so as to be attached to the upper part of the pubic ramus. By means of the technical scheme of the pressurizing anatomical bone fracture plate for symphysis pubis orthopedic, the pressurizing anatomical bone fracture plate for symphysis pubis orthopedics can reduce damage to symphysis pubis.

Description

technical field [0001] The invention relates to a pubic symphysis orthopedic pressurized anatomical bone plate. Background technique [0002] The incidence of pelvic fractures caused by high-energy trauma has been increasing in recent years. Pelvic fractures can easily lead to massive active bleeding and even threaten the lives of patients. In order to ensure the stability of the pelvis, it is necessary to ensure the stability of the anterior pelvic ring and the posterior pelvic ring. The study of pelvic biomechanics found that the anterior ring is very important for the stability of the entire pelvis, and accounts for 40%. Therefore, when performing anterior pelvic ring fracture surgery, it is necessary to fix the anterior ring. [0003] At present, common anterior ring fixation methods include: external fixation bracket, pedicle screw-rod system subcutaneous internal fixation technique (INFIX), percutaneous hollow screw fixation, and pubic plate fixation. Yet above-ment...

AI Technical Summary

Problems solved by technology

Yet above-mentioned various fixation methods all have its weak point

Defects of external fixator: pinhole infection, abscess formation, iliac bone osteomyelitis, aseptic loosening, loss of reduction, nerve injury, etc., and have obvious restrictions on the patient's position, and the incidence of related complications can reach 10% to 62% %

INFIX defects: the establishment of subcutaneous soft tissue channels and the penetration of crossbars may cause damage to the iliac vessels, femoral nerves, and bladder; the pressure of the iliopsoas and femoral nerve compartments caused by INFIX can cause femoral nerve paralysis; screw placement Too deep into the bone and insufficient pre-bending of the connecting rod will compress the femoral nerve and femoral artery; traction during the operation can easily damage the lateral femoral cutaneous nerve

Defects of percutaneous hollow nail fixation: it may damage the femoral artery and vein, obturator vascular nerve bundle and spermatic cord, and even stray into the acetabulum; it is not suitable for patients with abdominal wall infection or bladder injury

The traditional pubic symphysis plate and pubic ramus plate need to strip more soft tissue and periosteum, which often may damage the inguinal blood vessels, nerves, and bladder, and the fixation plane of a single plate is single, and the fixation effect is limited
