Complete Fractures Unveiled: Understanding Various Types and Implications Across Age Groups

Written by Jennifer Huynh, BSN, RN, NCSN

As we continue our journey of reviewing fractures, this post will focus on an essential category: complete fractures. These fractures involve a break in the continuity of a bone, and by delving into specific types and their implications, we can better understand how they affect individuals across various age groups.

One crucial aspect we must address is the profound impact of aging on bone density. Osteoporosis, a well-known health condition associated with the aging population, postmenopausal women, and individuals on medications that affect bone health, is of particular concern. In osteoporosis, the bone tissue breaks down faster than it can be rebuilt, leading to brittle and porous bones. Unfortunately, this condition often remains unnoticed until a fracture occurs, typically affecting the hip, spine, or wrist. Osteoporosis weakens the bones, significantly increasing the risk of fractures. It is imperative to be aware of this disease process and take appropriate measures to promote bone health and minimize fracture risks, especially in the older adult population.

Now, let's delve into specific types of complete fractures and their common locations:

Transverse Fractures: This type features a fracture line that runs perpendicular to the long axis of the bone, resulting in two distinct fragments. Transverse fractures can occur in individuals of all ages due to direct trauma or stress on the bone. Common locations include the shafts of long bones like the tibia, fibula, ulna, and humerus. They are often seen in accidents or falls where a significant force is applied to the bone, resulting in a clean break across the bone.

Impacted Fractures: In impacted fractures, the bone fragments are driven into each other, causing compression and often resulting in a stable configuration. These fractures commonly occur in adults, especially in long bones like the femur and radius. High-energy impacts or falls can lead to impacted fractures. For example, a fall from a height or a high-speed collision can cause the ends of the bone to be driven into each other, creating a compression effect.

Pathologic Fractures: Pathologic fractures occur when the bone is weakened by an underlying disease or condition, such as cancer or osteoporosis. These fractures can affect individuals of all ages, but they are more prevalent in older adults due to age-related bone density changes. Other conditions, such as infections, can also lead to pathologic fractures. The weakened bone cannot withstand normal pressure or stress, resulting in a fracture with minimal force. Common locations include the vertebrae, long bones, and bones affected by metastatic cancer.

Avulsion Fractures: Avulsion fractures involve a fragment of bone connected to a ligament or tendon that breaks off from the main bone. This fracture type is common in adolescents and young adults, as their bones are still developing and are more susceptible to avulsion injuries during sports or sudden, forceful movements. Common locations include the ankles, finger bones (phalanges), and pelvis. Avulsion fractures are often seen in athletes who experience sudden, forceful movements that cause the tendon or ligament to pull away from the bone, taking a small piece of the bone with it.

Compression Fractures: Compression fractures involve the bone being wedged or squeezed together on one side, reducing its height. These fractures are frequently seen in older adults, particularly in the spine's vertebrae. Osteoporosis is a common underlying cause of compression fractures. The weakened vertebrae can collapse under the body's weight or minor trauma, leading to a compression fracture. This type of fracture can cause significant pain and a reduction in height.

Displaced Fractures: Displaced fractures occur when one or multiple fragments of the bone are out of their normal alignment. These fractures can affect individuals of all ages, and treatment often involves reduction or realignment for proper healing. Common locations depend on the specific bone involved. For example, a displaced fracture of the radius, one of the bones in the forearm, may occur due to a fall on an outstretched hand, causing the bone fragments to shift out of place.

Extracapsular and Intracapsular Fractures: These types refer to the location of the fracture relative to a joint's capsule. Extracapsular fractures involve fragments that remain outside the joint capsule and are more common in adults, often affecting the hip and wrist. Intracapsular fractures extend into or within the joint capsule and may involve the hip or shoulder joint, impacting individuals of all ages. In older adults, intracapsular hip fractures are common and may require surgical intervention for proper healing.

Fragility Fractures: Fragility fractures are caused by low-level trauma and are more prevalent in older adults, usually associated with weakened bones due to conditions like osteoporosis. These fractures may occur with minimal force and are more common in older age groups. Common locations include the hip, spine, and wrist. Fragility fractures are often a significant concern in older adults, as they can lead to reduced mobility, loss of independence, and other complications.

As nurses, understanding the different types of complete fractures and their implications across various age groups is crucial for accurate assessment and appropriate care. Proper identification of fractures allows us to plan the most effective interventions and ensure optimal patient outcomes. By recognizing the specific fracture type and its location, nurses can provide targeted care and support to patients during their recovery journey.

For instance, when caring for an older adult patient with an intracapsular hip fracture due to osteoporosis, nurses need to be vigilant about the potential complications that may arise, such as deep vein thrombosis (DVT) or pressure ulcers during prolonged immobility. They can work closely with the healthcare team to implement preventive measures, encourage early mobilization, and provide pain management to promote healing and reduce complications.

In pediatric patients with avulsion fractures, nurses must approach care focusing on growth and development. Adolescents are often involved in various sports and physical activities, increasing their risk of avulsion injuries. Nurses can educate young patients and their parents on the importance of rest and rehabilitation while ensuring they understand the healing process.

Moreover, nurses play a vital role in patient education, empowering individuals of all ages to make informed decisions about their care and lifestyle choices. For patients with fragility fractures due to osteoporosis or other bone-related conditions, nurses can offer guidance on calcium and vitamin D supplementation, proper nutrition, and exercises to improve bone strength and reduce the risk of future fractures.

The knowledge of fracture types and their common locations also enables nurses to advocate for appropriate diagnostic tests and interventions. For example, suppose a patient with known osteoporosis presents with new back pain. In that case, nurses can recognize the potential for a compression fracture and advocate for appropriate imaging studies to confirm the diagnosis and guide treatment.

As we continue our exploration of fractures and their implications, let us remember the importance of a multidisciplinary approach to patient care. Nurses work collaboratively with physicians, physical therapists, occupational therapists, and other healthcare professionals to provide comprehensive care and support to patients with fractures. This teamwork ensures patients receive the best care tailored to their needs and circumstances.
