Injuries to the pelvis are typically caused by heavy blows, falls from height, crushing violence, or gunshot wounds. They can be categorized into three types: soft part bruising, bone fractures, and visceral injuries. The examination should aim to determine which category the injury belongs to.
Bruising of the soft parts is recognized by discoloration, dull aching pain, and swelling. Hematomas may appear as fine fluctuating swellings without skin bruising. Such swellings are most frequently found on the buttock. A contusion here can lead to abscess formation if indicated by increasing swelling, pain, tenderness, redness of the skin, local edema, and fluctuation.

Injuries to pelvic viscera must be ascertained next. The condition before injury should be known, including whether the bladder was full at the time. Pain, its position, character, and onset are crucial indicators of visceral injuries.
If blood is found escaping from the urethra or perineum bruising is present, a urethral laceration is likely. A catheter can confirm if the urethra is torn completely across. Rupture of the bladder varies in signs but often involves bleeding and inability to pass urine normally.

Foreign bodies in the rectum or vagina can be detected through digital examination. In the absence of a history, foreign bodies in the bladder are suspected if a child suddenly retains urine with slight hematuria.

Key Takeaways
- Injuries to the pelvis can be categorized into soft part bruising, bone fractures, and visceral injuries.
- Bruising of the soft parts is recognized by discoloration, pain, swelling, and possible hematoma formation.
- Fractures are diagnosed through careful examination for irregularities in bone outline or mobility.
Practical Tips
- Always check for bruising and swelling when assessing pelvic injuries.
- Use a catheter to confirm urethral lacerations and bladder ruptures.
- Digital examinations can detect foreign bodies in the rectum, vagina, or urethra.
Warnings & Risks
- Visceral injuries are often ambiguous and require thorough examination for accurate diagnosis.
- Fractures of the pelvis may be accompanied by significant pain and mobility issues.
Modern Application
While diagnostic methods have advanced significantly since 1884, understanding historical techniques remains crucial. Modern imaging technologies like X-rays and CT scans can confirm diagnoses more accurately than manual examination alone. However, knowing how to assess injuries manually is still essential in situations where such technology isn't available.
Frequently Asked Questions
Q: What are the typical causes of pelvic injuries?
Pelvic injuries typically result from heavy blows, falls from a height, severe crushing violence, or gunshot wounds.
Q: How do you diagnose a fracture in the pelvis?
To diagnose a fracture in the pelvis, place hands on each side of the symphysis pubis and run them along the bones to check for irregularities, mobility, or crepitus.
Q: What are signs of bladder rupture?
Signs of bladder rupture include severe pain, blood from the urethra, inability to pass urine normally, and sometimes a sudden increase in swelling in the perineum and scrotum.
