Study Notes

Pelvic Fractures Overview

Head, chest, and abdominal injuries commonly accompany pelvic fractures.
Fractures of extremities and spine can also occur with pelvic fractures.
Most hemorrhage results from exposed fractures, soft tissue injury, and local venous bleeding; arterial injuries play a lesser role.

Hematomas and Signs

Scrotal, labial, flank, and inguinal hematomas are common indicators of intrapelvic hemorrhage alongside pelvic ring injuries.

Mechanisms of Injury

Types of pelvic fracture mechanisms include:
- Anteroposterior compression (e.g., open book injury).
- Lateral compression.
- Vertical shear.
- Combined mechanisms.

Diagnosis

Diagnosis involves:
- Patient history and physical examination focusing on airway, breathing, circulation, disability, and exposure.
- Radiological examinations including AP view, inlet view, outlet view, and CT scans to assess displacement.

Management Protocols

Initial management includes airway control, breathing, circulation, disability assessment, and exposure while maintaining temperature.
For stable fractures:
- Rest and non-weight bearing advised.
- Pain management through analgesics.

Unstable Fractures

Unstable fractures require more aggressive management:
- Resuscitation phase focusing on blood loss management.
- External fixators reduce motion across the fracture surfaces to enhance clot formation and aid mobility.

Complications

Potential complications from pelvic fractures include:
- Hemorrhage and genitourinary injuries affecting bladder, urethra, ureters, and genital structures.
- GIT injuries and infections from open pelvic injuries.
- Thromboembolism and issues like malunion or nonunion leading to limb shortening.

Sacral Fractures Management

Stable fractures with less than 1 cm displacement managed conservatively (bed rest and gradual weight bearing).
Unstable fractures with more than 1 cm displacement typically need surgical fixation and possible decompression.

Complications of Sacral Fractures

Risks include non-union, malunion, incontinence, venous thromboembolism, and various surgical complications (infection, chronic pain, nerve injuries, and sexual function issues).

Acetabular Fractures

Types of acetabular fractures include anterior wall, posterior wall, and classified into columns (anterior column, posterior column, both columns).

Treatment of Acetabular Fractures

Undisplaced fractures management focuses on conservative methods such as skin traction.
Displaced fractures often require open reduction and internal fixation or skeletal traction if surgery is not feasible.

Long-Term Complications

Long-term issues associated with fractures include sciatic nerve injury, hip osteoarthritis, avascular necrosis of the femoral head, and hip instability.

Radiological Strategies

Standard x-rays essential for initial assessments; include specific views targeting fracture details (internal/external oblique views for better visualizing fracture lines).### Anatomy of the Pelvic Region
The innominate bone consists of three parts: ilium, pubis, and ischium.
Key ligaments include those of the pelvic ring, sacrum, symphysis pubis, and sacroiliac joint.

Types of Pelvic Fractures

Low Energy Fractures: Common in elderly with osteoporosis; often due to falls or stress injuries.
Avulsion Fractures: Occur in younger patients from muscle contractions, affecting areas like ASIS (sartorius muscle) and AIIS (rectus femoris).
Direct Fractures: Includes single breaks in the pelvic ring; types are fractures of iliac bone, pubic/ischial bone, sacroiliac joint subluxation, and diastasis of the symphysis pubis.

Classification of Fractures

Stable Fractures: Characterized by isolated breaks; symptoms include localized tenderness with treatment via bed rest and physiotherapy.
Unstable Fractures: More than one break in the pelvic ring; require careful management due to increased risks associated with injury.

Associated Complications

Early complications: General shock, hemorrhage, local vital structure injuries.
Late complications: Deep vein thrombosis (DVT), persistent pain, limb length discrepancies.

Clinical Management

Assessment: Includes airway management, breathing, circulation, disability, and exposure.
Stable Fractures Management: Rest, non-weight bearing activities, and pain management.
Unstable Fractures Management: Resuscitation, possibly requiring external fixation and management of hemorrhage.

Radiologic Examination

Common Views: Anterior-posterior (AP), inlet (anterior/posterior displacement), and outlet (vertical displacement) views are crucial for diagnosis.
CT scans provide detailed visualization of fractures and associated injuries.

Complications of Sacral Fractures

Stable fractures (less than 1 cm displacement): Managed with bed rest and weight bearing.
Unstable fractures (over 1 cm displacement): Require surgical fixation and possible decompression.
Possible outcomes: Non-union, malunion, incontinence, thromboembolism, and sexual dysfunction.

Mechanisms of Injury

Anteroposterior Compression: Can lead to open book injuries.
Lateral Compression: Results in lateral compression fractures.
Vertical Shear Injuries: Different injury mechanism requiring distinct diagnostic approaches.

Bleeding Sources

Pelvic fractures commonly involve bleeding from fractured surfaces, small venous or arterial tears, and major vessel disruption.

Treatment of Fractures

Undisplaced fractures treated conservatively with traction.
Displaced fractures may require open reduction and internal fixation or skeletal traction if surgical risk is high.
Complications include sciatic nerve injury, avascular necrosis of the femoral head, and hip instability.

Summary

Pelvic fractures are complex injuries with significant implications, necessitating careful management to address structural and functional outcomes. Key considerations include the type of fracture, potential complications, and a structured approach to assessment and intervention.### Limb Shortening Complications
Early complications include general shock, hemorrhage (Hge), and local vital structure injuries.
Late complications may involve deep vein thrombosis (DVT), persistent pain, and length discrepancy.

Management of Sacral Fractures

Stable fractures (less than 1cm displacement) are managed with bed rest and gradual weight-bearing.
Unstable fractures (more than 1cm displacement) require surgical fixation, potentially with decompression.

Complications of Sacral Fractures

Risks include non-union, malunion, incontinence of urine and stool, and venous thromboembolism.
Surgical complications may arise such as hardware prominence, infection, chronic pain, and iatrogenic nerve injury.
Sexual complications can also occur.

Acetabular Fractures Classification

Fractures are categorized by parts of the acetabulum: anterior wall, posterior wall, and column fractures.
Types include anterior column fractures, posterior column fractures, and both columns fractures.

Diagnostics for Acetabular Fractures

Standard diagnosis utilizes plain X-rays and specific views:
- Internal oblique view for posterior lip, anterior column.
- External oblique view for anterior lip, posterior column.

Treatment Approaches

Undisplaced fractures respond well to conservative treatment and skin traction.
Displaced fractures necessitate open reduction with internal fixation or skeletal traction if surgical conditions are unsuitable.

Complications of Acetabular Fractures

Potential complications include sciatic nerve injury, osteoarthritis of the hip, avascular necrosis of the femoral head, and hip instability.

Pelvic Fractures Overview

Commonly associated with abdominal, chest, and head injuries, as well as fractures of extremities and spine.
Major hemorrhage typically stems from soft tissue injuries, local venous bleeding, or exposed fractures; arterial injuries are less common.

Indications of Intrapelvic Hemorrhage

Scrotal, labial, flank, and inguinal hematomas may indicate pelvic ring injuries and accompanying hemorrhage.

Mechanism of Injury Classifications

Injuries categorized as:
- Anteroposterior compression (e.g., open book injuries)
- Lateral compression
- Vertical shear
- Combined mechanisms

Diagnosis of Pelvic Fractures

Diagnosis involves taking a history and performing physical examinations focused on airway, breathing, and circulation (ABC) while checking for associated injuries.

Innominate Bone Structure

Composed of three parts: ilium, pubis, and ischium.

Pelvic Ring Ligaments

Include ligaments connecting sacrum to ischium, sacroiliac joint (SIJ), and pubic symphysis.

Low Energy Pelvic Fractures

Commonly seen in elderly patients through domestic falls and stress fractures, often related to osteoporosis.
Can also involve avulsion injuries from large muscle contractions in younger patients.
Isolated fractures result in stable fractures with localized tenderness and require bed rest followed by physiotherapy.

High Energy Pelvic Fractures

Associated with multiple breaks in the pelvic ring and considered unstable; often require more extensive diagnostic and treatment approaches.
Injuries to associated organ systems frequently observed due to the energy transfer during injury.
