Disease Description (Causes and Symptoms)

• Definition and pathophysiology: The clavicle (collarbone) is a long bone that connects the sternum and scapula, securing the shoulder to the trunk. If a crack or complete fracture occurs in the clavicle due to trauma (a direct blow, falling onto an outstretched hand, a traffic accident, or neonatal injury during childbirth), the fracture fragments may become displaced due to the pull of the surrounding muscles. Fractures of the middle portion (shaft) are the most common. Severe displacement, open fractures, and injuries to nearby nerves or blood vessels may occur.
• Main symptoms: Local pain, swelling, tenderness, a sharp protrusion toward the shoulder (displacement of the bone fragment), and pain with arm or shoulder movement. Rarely, an open fracture that breaks through the skin, sensory or motor abnormalities due to injury to the brachial plexus or subclavian vessels, impaired blood flow (paleness or coldness of the hand), or breathing difficulty (in cases of pleural injury or pneumothorax) may occur.
• Diagnostic summary: Medical history (mechanism of injury) and physical examination (assessment of local tenderness, deformity, and neurovascular status). The basic test is a plain X-ray of the clavicle (anteroposterior view, with a 45° cephalic tilt if necessary). CT or chest imaging (to check for pneumothorax) may be added if the fracture is complex, involves a joint, has severe displacement, or an associated chest injury is suspected.

Treatment Methods

• Conservative treatment (in most cases):
  • Acute pain control: Rest, ice application, and pain relievers (acetaminophen or short-term NSAIDs).
  • Immobilization: Support the shoulder with a figure-of-eight bandage or sling to stabilize the fracture fragments. Immobilization is generally about 3–4 weeks in children and 6–8 weeks in adults (the rate of bone union varies by individual).
  • Rehabilitation: After the initial immobilization, range-of-motion recovery and muscle-strengthening exercises (physical therapy). Gradual resumption of activities depending on pain and radiographic evidence of union.
• Surgical treatment (considered in the following cases):
  • Open fracture, nerve or vascular injury, or vascular compression (loss of pulse, peripheral ischemia),
  • Severe displacement (marked shortening or deformity), multiple trauma, or when rapid functional recovery is desired in a highly active patient,
  • Nonunion or malunion causing functional problems.
  • Methods: Metal plate fixation (plate-screw fixation), intramedullary pinning, and reduction and fixation. Bone grafting or other adjunctive procedures may be performed if necessary.
• Medications and additional treatment:
  • Open fractures require appropriate cleansing, antibiotics, and tetanus prevention.
  • NSAIDs are commonly used for pain control, but because high-dose or long-term use may potentially affect bone union, discuss this with the treating physician.
• Precautions and risk of complications:
  • Nerve or vascular injury (brachial plexus, subclavian vessels), nonunion or malunion, chronic pain, and pneumothorax due to pleural injury (rare).
  • Open fractures have an increased risk of infection.
  • If severe pain, loss of sensation, or a pale, pulseless hand develops during treatment, immediate emergency evaluation is necessary.

Pre-Outpatient Visit Checkpoints (Including Suggested Items to Bring and Questions)

• Recommended items to bring:
  • A list of all medications currently being taken (including prescription drugs, OTC medications, and supplements)
  • Previous tests and imaging (such as prior X-rays or CT scans, if available)
  • A record of when and how the injury occurred (mechanism) and changes in symptoms (pain intensity, presence of numbness or tingling, presence of a wrist pulse, etc.)
  • Photos (if the shoulder deformity is clearly visible)
• Checkpoints before the outpatient visit:
  • Pain level (0–10), and the difference between resting and moving
  • Skin condition (whether there is warmth, redness, skin penetration, or bleeding)
  • Sensation and motor function of the hand and fingers (not the ankle, but a simple check of the upper limb)
  • Whether breathing difficulty or neck or chest pain is also present
• Information helpful for the consultation:
  • Whether there are multiple injuries (other injuries to the chest, upper limbs, pelvis, etc.)
  • Occupation and activity or exercise level (may affect treatment goals and the decision to operate)

Examples of General Questions to Ask the Doctor

• "Does my fracture require surgery? Is nonsurgical treatment sufficient?"
• "What is the expected recovery period, and when can I return to daily activities such as driving, work, and sports?"
• "What are the main side effects of the prescribed medication, and what precautions should I take when taking it?"
• "When should physical therapy begin, and at what intensity?"

Examples of Disease-Specific Questions

• "Could you explain whether the degree of displacement of the fracture fragments on my X-ray meets the criteria for surgery?"
• "An open fracture (or nerve or vascular symptoms) is suspected. Is this a situation requiring emergency surgery or additional imaging, such as CT or angiography?"
