Pubic symphysis dissection type vertical locking bone plate

Abstract

The invention discloses a pubic symphysis dissection type vertical locking bone plate. The bone plate is mainly applied to pubic symphysis separation caused by trauma and placed in front of and on theupper edge of pubic symphysis during open reduction treatment of pubic symphysis separation with pubic symphysis anterior approach (Pfannenstiel incision) to achieve the treatment purposes of anatomical reduction and internal fixation reinforcement.

Description

technical field [0001] The invention relates to an anatomical vertical locking bone plate of the pubic symphysis, which is used for open reduction of the pubic symphysis anterior approach (Pfannenstiel incision) to treat pubic symphysis separation, and is placed on the front and upper edge of the pubic symphysis to achieve anatomical reduction and strong internal fixation the purpose of treatment. Background technique [0002] Currently, pelvic ring injuries account for approximately 3% of all skeletal injuries throughout the body. In pelvic ring injuries, pubic symphysis separation is a common form of injury, mostly caused by high-energy injuries, and pelvic ring injuries combined with pubic symphysis separation account for 24% of pelvic fractures. [0003] Separation of the pubic symphysis is a typical open book-like injury, which destroys the integrity of the pelvic ring, the sense of restraint disappears, the pelvic ring loses its stable state, and the sacrum becomes un...

AI Technical Summary

Problems solved by technology

However, the single-plane steel plate has insufficient shearing effect against the vertical direction of the pelvis, and it is often prone to fracture failure of the internal fixation.

At present, two reconstruction plates are mostly used, which are placed vertically on the front surface and upper edge of the pubic symphysis. However, the disadvantages of biplane fixation of the two reconstruction plates are that it requires multiple bending and shaping during the operation, the fixation strength is poor, and the stress load Concentration, unreliable fixation, easy to loosen and break
