1. Spur sign
The spur-like presentation of the lateral bone of the main bone (the remnant of the iliac normally attached to the trunk) on a pelvic flat sheet (preferably on a closed-hole oblique piece) is a characteristic sign of a bispolar fracture of the acetabular.
2. Gull wing sign
Signs similar to seagull wingspan on orthotopic pelvic plates are characteristic of compression fractures of the medial articular surface of the usuar apex and corresponding subchondral bone, generally indicating poor prognosis.
3. "Wind-curled pelvis"
On the basis of lateral squeeze (LC) grade 1 or grade 2 ipsilateral injury, lateral violence continues to act on the contralateral pelvis, resulting in contralateral pelvic spinosacral ligament, sacrotus nodular ligament, and sacroiliac anterior ligament injury, resulting in book-like injury, also known as "Windswept" pelvic.
4. Book-like fracture
Pubic joint rupture and extensive separation in front of the pelvic ring, tearing of the anterior sacroiliac ligament with mild separation of the sacritis iliac joint, but intact posterior sacroiliac ligament prevents the displacement of the pelvis in the vertical direction.
5. Riding transistor fracture (sphenoid fracture)
Disruption of the bilateral inferior branch of the pubic bone anterior to the pelvic ring causes instability, and displacement is often insignificant, but may cause damage to internal organs, especially the urogenitourinary, and generally to posterior urethral membrane injury.
Small extension:
Clinically, the urethra of men is divided into anterior and posterior urethra. The posterior urethra generally includes the prostate urethra and the membranous urethra. The anterior urethra generally includes the bulbous urethra and the cavernous urethra.
The narrowest part of the male urethra is the membrane urethra, which is clinically prone to inflammatory stenosis. In pelvic fractures, it is easy to cause damage to the membrane urethra.
Common perineal riding straddle injuries can easily damage the urethra of the ball, causing ball urethral damage. In addition, there are three stenosises in the urethra, namely the inner orifice of the urethra, the outer orifice of the urethra, and the membranous part.
6. Vertical shear damage
Upward and posterior dislocation of the sacroiliac joint with ipsilateral pubic upper and lower branch fractures, resulting in upward displacement of the hemilateral pelvis. Associated injuries include fractures of the 5th lumbar transverse process, sciatic spine avulsion fractures, and traction of the sacral nerve.
7, new moon fracture
Iliac fracture dislocation involving the articular surface. May be accompanied by damage to the L5 nerve root.
