Fractures

Definition and Causes of Fractures

A fracture is a complete or partial break in the continuity of a bone structure. When the force applied to a bone exceeds its tensile strength, the bone tissue yields and breaks.

Common causes include:

Classification and Types of Fractures

Fractures are categorized based on their pattern, the integrity of the surrounding skin, and the degree of bone displacement. Understanding these types helps nurses anticipate specific interventions.

ClassificationDescriptionClinical Significance
Closed (Simple)Skin remains intact over the fracture site.Lower risk of external bacterial contamination.
Open (Compound)Broken bone protrudes through the skin or a wound leads to the fracture.High risk of osteomyelitis and severe infection.
GreenstickBone is splintered on one side and bent on the other; common in children.Heals relatively quickly due to flexible pediatric bone.
ComminutedBone breaks into three or more pieces.Often requires surgical fixation for proper alignment.

Clinical Manifestations

The clinical presentation of a broken bone varies depending on the site and severity, yet several classic signs consistently appear during assessment. Nurses must systematically evaluate these indicators.

The Bone Healing Process

Bone repair is a unique physiological regeneration process rather than mere scar formation. It proceeds through distinct overlapping phases to restore full structural integrity.

  1. Hematoma Formation: Bleeding from fractured bone vessels forms a clot at the site within the first 24 to 72 hours.
  2. Fibrocartilaginous Callus Formation: Granulation tissue invades the hematoma, and fibroblasts and chondroblasts form a soft bridge of cartilage and fibrous tissue.
  3. Bony Callus Formation: Osteoblasts deposit spongy bone, converting the soft callus into a hard bony bridge over several weeks.
  4. Remodeling: Osteoclasts resorb excess bony debris while osteoblasts lay down compact bone along lines of stress, restoring the original bone contour.

Emergency Management and Immediate Care

Immediate nursing care at an accident scene focuses on preventing further injury, controlling hemorrhage, and stabilizing the patient.

Never attempt to realign or push protruding bone ends back beneath the skin in an open fracture. Instead, cover the wound with a sterile dressing to minimize infection risks. Immobilize the joint above and below the fracture site using splints before moving the patient. Conduct frequent neurovascular assessments—checking pulse, color, temperature, and capillary refill—to ensure adequate distal tissue perfusion.

Medical and Surgical Interventions

Treatment aims to achieve reduction—setting the bone back into proper alignment—and immobilization until healing occurs.

Closed reduction involves manual manipulation of the bone under anesthesia, followed by casting or traction. Open reduction internal fixation (ORIF) requires surgical incision to align bone fragments, securing them with metal plates, screws, or intramedullary nails. External fixation uses transfixing pins inserted through the skin and bone into a rigid external frame, commonly utilized for complex open fractures with extensive soft tissue damage.

Potential Complications

Fractures can trigger local and systemic complications that threaten limb viability and patient survival if unrecognized.

Nursing Care Plan and Rehabilitation

Comprehensive nursing care extends from acute admission through rehabilitation. Interventions focus on pain control, skin integrity maintenance, and promoting independence.

Nurses must regularly inspect cast edges for roughness and check skin under traction ropes. Encourage deep breathing exercises to prevent atelectasis from immobility. Collaborate with physical therapists to teach safe ambulation techniques using assistive devices like crutches or walkers. Nutritional support rich in calcium, vitamin D, and protein is vital to facilitate bone matrix synthesis.
