Fractures in the spine can significantly impact an individual's quality of life, causing pain, reduced mobility, and even leads to disability.wedge and compression fractures are two important types among the various types of spinal fractures.A wedge fracture results in a wedge-shaped deformity of the vertebra, while a compression fracture involves the general collapse of the vertebra.
Comparative Table: Wedge vs Compression Fractures
Below is the difference between Wedge and Compression Fractures in the tabular format:
| Aspect | Wedge Fracture | Compression Fracture |
| Fracture Shape | Wedge-shaped deformity | General vertebral collapse |
| Location | Often in the thoracic spine | Can occur anywhere in the spine |
| Causes | Primarily osteoporosis, but also trauma | Osteoporosis, trauma, cancer, high-impact events |
| Symptoms | Localized sharp pain, hunched posture, limited mobility | Sudden back pain, pain worsens with movement, kyphosis |
| Risk Factors | Osteoporosis, age, trauma | Osteoporosis, trauma, cancer, advanced age |
| Imaging Diagnosis | X-rays, MRI, CT scans | X-rays, MRI, CT scans |
| Conservative Treatment | Pain management, bracing, physical therapy | Pain management, bracing, physical therapy |
| Surgical Treatment | Vertebroplasty, kyphoplasty | Vertebroplasty, kyphoplasty, spinal fusion, decompression surgery |
| Prevention | Bone density testing, medication, exercise, nutrition, fall prevention | Bone density testing, medication, exercise, nutrition, fall prevention |

What is a Compression Fracture?
A compression fracture occurs when one or more vertebrae in the spine break.This can cause the vertebrae to collapse and become shorter, which can lead to bone fragments pressing on the spinal cord and nerves. This can reduce the amount of oxygen and blood that reaches the spinal cord.
Causes
- This type of fracture typically results from a combination of osteoporosis and trauma. Osteoporosis: The most significant risk factor for compression fractures is osteoporosis. As bones become less dense and more brittle, they are more prone to fractures.
- Trauma: Falls, car accidents, and other high-impact events can cause compression fractures, particularly in individuals with weakened bones.
- Cancer: Certain cancers, such as multiple myeloma and metastatic disease, can weaken the vertebrae, leading to fractures.
- Age: The risk of compression fractures increases with age due to the natural decline in bone density.
Symptoms
The symptoms of a compression fracture can vary depending on the severity and location of the fracture. Common symptoms include:
- Sudden onset of back pain, often after a minor injury
- Pain that worsens with movement or standing and improves with rest
- Loss of height over time
- Kyphosis, or a stooped forward posture
- Limited spinal mobility
What is a Wedge Fracture?
A wedge fracture is a specific type of compression fracture where the front part of a vertebra collapses, creating a wedge-shaped deformity. This type of fracture is most common in the thoracic (mid-back) and lumbar (lower back) regions of the spine. Wedge fractures are also associated with osteoporosis but can also result from traumatic injuries.
Causes
The causes and risk factors for wedge fractures are similar to those for other compression fractures. Osteoporosis remains the most significant risk factor, followed by trauma and certain medical conditions. High-energy trauma, such as car accidents or falls from significant heights, can also cause wedge fractures in healthy individuals.
Symptoms of Wedge Fractures
The symptoms of a wedge fracture are similar to those of other compression fractures, but the specific shape of the deformity can lead to additional issues:
- Sharp, localized back pain
- Increased pain with sitting or standing
- Loss of spinal alignment, leading to a hunched or stooped posture
- Difficulty walking or moving

Key Differences Between Compression Fracture and Wedge Fracture
- Fracture Shape: Wedge fractures create a wedge-shaped deformity, while compression fractures involve general vertebral collapse.
- Location: Wedge fractures often occur in the thoracic spine, compression fractures can occur anywhere.
- Causes: Both can result from osteoporosis or trauma, but wedge fractures are more commonly associated with osteoporosis.
