Summary about Disease
A pathological fracture is a broken bone that occurs in an area of bone weakened by an underlying disease. Unlike fractures caused by significant trauma, pathological fractures happen due to minimal or no injury. These fractures often indicate a serious underlying condition affecting bone strength.
Symptoms
Pain in the affected area, which may worsen over time.
Swelling or tenderness around the fracture site.
Difficulty using or moving the affected limb or area.
Deformity of the bone in severe cases.
A fracture may occur after only minimal trauma or even during normal activities.
Causes
Osteoporosis: A common condition causing decreased bone density.
Cancer (Metastatic): Cancer that has spread to the bone from other parts of the body. Common primary cancers include breast, prostate, lung, kidney, and thyroid.
Bone Tumors (Primary): Tumors that originate in the bone itself (benign or malignant).
Infections: Osteomyelitis (bone infection) can weaken the bone.
Genetic Bone Disorders: Conditions like osteogenesis imperfecta.
Paget's Disease: A chronic disorder that disrupts the normal bone remodeling process.
Other Conditions: Hyperparathyroidism, renal osteodystrophy, and certain medications (e.g., long-term corticosteroid use) can weaken bones.
Medicine Used
The medicines used to treat pathological fractures vary depending on the underlying cause of the weakened bone.
Pain Management: Analgesics (pain relievers) such as acetaminophen, NSAIDs (nonsteroidal anti-inflammatory drugs), or opioids.
Osteoporosis Treatment: Bisphosphonates (alendronate, risedronate, zoledronic acid), denosumab, teriparatide, romosozumab, and calcium/vitamin D supplements.
Cancer Treatment: Chemotherapy, radiation therapy, hormone therapy, targeted therapy, and immunotherapy to treat the underlying cancer causing the bone weakening.
Bone-Targeted Therapies for Cancer: Bisphosphonates and denosumab to strengthen bone and reduce the risk of further fractures.
Antibiotics: For fractures caused by infection (osteomyelitis).
Medications for Paget's Disease: Bisphosphonates.
Medications for Hyperparathyroidism: Vitamin D and calcium supplements, calcimimetics, surgery.
Is Communicable
No, a pathological fracture itself is not communicable. However, if the underlying cause is an infection (like osteomyelitis), the infection might be communicable, but not the fracture itself.
Precautions
Address Underlying Condition: The primary focus is on treating the underlying disease that caused the bone weakening.
Fall Prevention: Implement measures to prevent falls, especially for individuals with osteoporosis or other conditions that increase fracture risk (e.g., removing tripping hazards, using assistive devices).
Nutrition: Ensure adequate intake of calcium and vitamin D for bone health.
Weight Management: Maintain a healthy weight to reduce stress on bones.
Regular Exercise: Weight-bearing exercises can help strengthen bones (under the guidance of a healthcare professional).
Medication Adherence: Follow prescribed medication regimens for the underlying condition and bone health.
Avoid Smoking and Excessive Alcohol Consumption: These habits can negatively impact bone health.
How long does an outbreak last?
A pathological fracture is not an outbreak, rather an incident that takes place with individuals with the listed dieases.
How is it diagnosed?
Physical Examination: To assess the affected area for pain, swelling, and deformity.
Imaging Studies:
X-rays: To visualize the fracture and assess bone structure.
Bone Scan: To detect areas of abnormal bone activity, such as tumors or infections.
MRI (Magnetic Resonance Imaging): To provide detailed images of the bone and surrounding tissues.
CT Scan (Computed Tomography Scan): To provide cross-sectional images of the bone.
Bone Biopsy: In some cases, a bone biopsy may be performed to analyze the bone tissue for cancer, infection, or other abnormalities.
Blood Tests: To evaluate calcium levels, vitamin D levels, parathyroid hormone levels, and markers of bone turnover. Blood tests can also help identify underlying conditions such as cancer or infection.
Review of Medical History: To identify any pre-existing conditions that could contribute to bone weakening.
Timeline of Symptoms
The timeline of symptoms can vary widely depending on the underlying cause and the severity of the bone weakening.
Gradual Onset: In some cases, pain may develop gradually over weeks or months as the underlying condition weakens the bone.
Sudden Onset: The fracture itself may cause sudden, severe pain, especially if it occurs with minimal trauma.
Progression: Pain may worsen over time if the fracture is not treated or if the underlying condition progresses.
Associated Symptoms: Other symptoms may develop depending on the underlying cause, such as fatigue, weight loss (in the case of cancer), or fever (in the case of infection).
Important Considerations
Underlying Cause is Key: The primary focus is on identifying and treating the underlying condition responsible for the bone weakening.
Multidisciplinary Approach: Management often involves a team of specialists, including orthopedists, oncologists, endocrinologists, and radiologists.
Stabilization: Fractures may require surgical stabilization with plates, screws, rods, or bone cement to provide support and promote healing.
Pain Management: Adequate pain control is essential for improving quality of life.
Rehabilitation: Physical therapy and occupational therapy can help restore function and mobility after fracture repair.
Prognosis: The prognosis depends on the underlying cause, the extent of bone damage, and the individual's overall health. Addressing the primary condition improves the long term outcome.
