Fracture of the Arm

Overview

A fracture of the arm refers to a break in any of the three major bones that make up the upper extremity: the humerus (upper arm bone), radius (thumb-side forearm bone), or ulna (pinky-side forearm bone). These fractures are among the most common orthopedic injuries, affecting people of all ages from children learning to walk to elderly individuals at risk of falls. The severity can range from small cracks (hairline fractures) to complete breaks where the bone is separated into two or more pieces.

Arm fractures significantly impact daily activities, as the arms are essential for most tasks including eating, dressing, working, and maintaining balance. The location and type of fracture determine the treatment approach and recovery timeline. Upper arm fractures (humerus) often occur near the shoulder or elbow joints, while forearm fractures (radius and ulna) commonly happen near the wrist. Understanding the specific type of fracture is crucial for appropriate treatment and optimal recovery.

Modern medical advances have greatly improved outcomes for arm fractures. Treatment options range from simple immobilization with casts or splints to complex surgical procedures involving plates, screws, or rods. Most arm fractures heal well with proper treatment, though the recovery process requires patience and often includes physical therapy to restore full strength and range of motion. Early recognition and appropriate treatment are key to preventing complications and ensuring the best possible functional outcome.

Symptoms

Recognizing the symptoms of an arm fracture is crucial for seeking timely medical attention. The symptoms can vary depending on the location and severity of the fracture, but certain signs are common across all types of arm fractures. Immediate recognition of these symptoms helps prevent further injury and ensures appropriate treatment.

Primary Symptoms

Causes

Arm fractures result from forces that exceed the strength of the bone. The specific cause often determines the type and pattern of fracture. Understanding these causes helps in both treatment planning and prevention strategies. Different age groups tend to experience arm fractures from different mechanisms of injury.

Traumatic Causes

Falls

The most common cause of arm fractures across all age groups:

• FOOSH injuries: Fall On an OutStretched Hand, causing radius or ulna fractures
• Direct impact falls: Landing directly on the arm or shoulder
• Height falls: Falls from ladders, stairs, or elevated surfaces
• Same-level falls: Tripping or slipping accidents

Sports Injuries

Athletic activities account for many arm fractures:

• Contact sports (football, hockey, rugby)
• Extreme sports (skateboarding, snowboarding, mountain biking)
• Gymnastics and cheerleading
• Baseball and softball (sliding injuries)
• Martial arts and combat sports

Motor Vehicle Accidents

• Direct impact from dashboard or steering wheel
• Bracing against impact
• Ejection from vehicle
• Motorcycle accidents (high-energy trauma)

Pathological Causes

Some fractures occur due to weakened bone structure:

• Osteoporosis: Age-related bone density loss
• Bone tumors: Both benign and malignant
• Metabolic disorders: Affecting bone strength
• Medications: Long-term steroid use weakening bones
• Nutritional deficiencies: Vitamin D or calcium deficiency

Stress Fractures

Repetitive stress can cause small cracks in arm bones:

• Overuse in throwing sports (baseball, javelin)
• Weight-bearing activities (gymnastics, pole vaulting)
• Military training or occupational repetitive tasks

Diagnosis

Accurate diagnosis of arm fractures is essential for proper treatment planning. The diagnostic process combines clinical examination with imaging studies to determine the exact location, type, and severity of the fracture. Modern imaging techniques allow for precise visualization of bone injuries and associated soft tissue damage.

Initial Assessment

Medical History

• Mechanism of injury (how the fracture occurred)
• Time of injury and initial symptoms
• Previous fractures or bone conditions
• Current medications and medical conditions
• Occupation and activity level
• Dominant hand (for treatment planning)

Physical Examination

The healthcare provider will assess:

• Visual inspection: Deformity, swelling, bruising, wounds
• Palpation: Point tenderness, crepitus (grinding sensation)
• Range of motion: Active and passive movement assessment
• Neurovascular status: Sensation, pulse, capillary refill
• Associated injuries: Other body areas affected

Imaging Studies

X-rays

The primary diagnostic tool for fractures:

• Multiple views (anteroposterior, lateral, oblique)
• Include joints above and below the injury
• Comparison views of the uninjured arm (in children)
• Stress views for ligament injuries

Advanced Imaging

• CT scan: Complex fractures, surgical planning, intra-articular fractures
• MRI: Soft tissue injuries, stress fractures, pathological fractures
• Bone scan: Occult fractures, stress fractures
• Ultrasound: Pediatric fractures, real-time assessment

Fracture Classification

Fractures are classified by several characteristics:

• Location: Proximal, midshaft, or distal
• Pattern: Transverse, oblique, spiral, comminuted
• Displacement: Non-displaced or displaced
• Skin integrity: Closed or open (compound)
• Joint involvement: Extra-articular or intra-articular

Special Considerations

• Pediatric fractures: Growth plate assessment (Salter-Harris classification)
• Elderly patients: Bone quality evaluation, fall risk assessment
• Athletes: Return-to-play considerations
• Occupational requirements: Job-specific functional needs

Treatment Options

Treatment for arm fractures depends on multiple factors including the type and location of fracture, patient age, activity level, and overall health. The primary goals are to restore anatomy, promote healing, and return function while minimizing complications. Treatment approaches range from conservative management to complex surgical interventions.

Non-Surgical Treatment

Immobilization

Most stable, non-displaced fractures can be treated without surgery:

• Casting: Plaster or fiberglass casts for stable fractures
• Splinting: Initial treatment allowing for swelling
• Functional bracing: Allows some movement while protecting the fracture
• Sling immobilization: For proximal humerus fractures

Closed Reduction

Realigning displaced fractures without surgery:

• Performed under sedation or local anesthesia
• Manual manipulation to restore alignment
• Followed by immobilization
• Regular X-rays to monitor alignment

Surgical Treatment

Internal Fixation

Various surgical techniques to stabilize fractures:

• Plates and screws: Metal implants holding bone fragments
• Intramedullary nails: Rods inserted through bone canal
• Pins and wires: For smaller fragments or pediatric fractures
• External fixation: Pins connected to external frame

Surgical Indications

• Open (compound) fractures
• Displaced intra-articular fractures
• Multiple fracture fragments (comminuted)
• Failed conservative treatment
• Associated neurovascular injury
• Polytrauma patients

Pain Management

• Acute phase: NSAIDs, acetaminophen, short-term opioids
