Which nerve arises from the inflammation and can be affected post-fracture?

• A. Ulnar nerve
• B. Radial nerve
• C. Median nerve
• D. Inferior alveolar nerve

Answer: (B)

The radial nerve is particularly associated with post-fracture complications, especially in scenarios involving the humerus. When there is a mid-shaft humeral fracture, the radial nerve can be injured due to its anatomical path, which runs in close proximity to the humerus. This type of trauma may lead to symptoms like wrist drop, characterized by the inability to extend the wrist and fingers due to paralysis of the extensor muscles innervated by the radial nerve. The other nerves listed have different anatomical considerations. For instance, the ulnar and median nerves are typically associated with injuries involving the elbow or wrist, but they do not usually arise from the inflammation of fractures in the humerus. The inferior alveolar nerve is mainly associated with dental procedures and mandibular fractures, and not with major limb fractures, making it less relevant in the context of trauma-related nerve injuries.
