Clavicle Fracture Complications: What to Watch Out For

A clavicle fracture, also known as a broken collarbone, is a common injury that can occur due to various reasons such as sports injuries, falls, or accidents. While most clavicle fractures heal well with proper treatment and care, there can be complications that may arise during the healing process. It is important to be aware of these complications and know what to watch out for to ensure timely intervention and prevent further damage. In this article, we will explore some of the common complications associated with clavicle fractures and discuss the signs and symptoms that should not be ignored.

1. Nonunion

Nonunion refers to the failure of the fractured clavicle to heal properly. This complication can occur when the broken ends of the bone do not come together or remain separated despite the passage of time. Nonunion is more likely to occur in cases where the fracture is severe, the bone fragments are displaced, or there is inadequate blood supply to the fractured area.

Signs and symptoms of nonunion may include:

  • Persistent pain and tenderness at the fracture site
  • Difficulty in moving the arm or shoulder
  • Visible deformity or abnormality in the clavicle
  • Delayed or lack of improvement in symptoms over time

If nonunion is suspected, further evaluation such as X-rays or CT scans may be necessary to confirm the diagnosis. Treatment options for nonunion may include surgical intervention to realign the bone fragments and promote healing.

2. Malunion

Malunion occurs when a clavicle fracture heals in an abnormal position or alignment. This can happen if the broken ends of the bone are not properly aligned during the healing process. Malunion can lead to functional limitations, cosmetic concerns, and increased risk of future fractures.

Signs and symptoms of malunion may include:

  • Visible deformity or asymmetry in the clavicle
  • Persistent pain or discomfort
  • Restricted range of motion in the shoulder or arm
  • Difficulty in performing daily activities

Treatment options for malunion depend on the severity of the misalignment and the impact on the individual’s quality of life. In some cases, surgical intervention may be necessary to correct the malalignment and improve function.

3. Infection

Infection is a potential complication that can occur after a clavicle fracture, particularly if an open fracture (where the bone breaks through the skin) or surgical intervention is involved. Infection can delay the healing process and lead to further complications if not promptly treated.

Signs and symptoms of infection may include:

  • Increased pain, redness, or swelling at the fracture site
  • Drainage of pus or fluid from the wound
  • Fever or chills
  • Generalized malaise or feeling unwell

If infection is suspected, medical attention should be sought immediately. Treatment typically involves antibiotics to control the infection and, in severe cases, surgical debridement to remove infected tissue.

4. Nerve Damage

Clavicle fractures can sometimes result in nerve damage, particularly if the fracture fragments impinge on or compress nearby nerves. The nerves most commonly affected in clavicle fractures are the brachial plexus nerves, which control movement and sensation in the arm and shoulder.

Signs and symptoms of nerve damage may include:

  • Numbness or tingling in the arm, hand, or fingers
  • Weakness or paralysis in the arm or shoulder
  • Loss of sensation or muscle control
  • Difficulty in performing fine motor tasks

If nerve damage is suspected, a thorough neurological examination and imaging studies may be necessary to assess the extent of the injury. Treatment options for nerve damage may include physical therapy, medication, or, in severe cases, surgical intervention to repair or reconstruct the damaged nerves.

5. Shoulder Impingement

Shoulder impingement is a common complication that can occur during the healing process of a clavicle fracture. It happens when the fractured ends of the clavicle impinge on the surrounding structures in the shoulder joint, such as the rotator cuff tendons or the acromion process of the scapula.

Signs and symptoms of shoulder impingement may include:

  • Pain or discomfort in the shoulder, particularly with overhead activities
  • Weakness or loss of strength in the affected arm
  • Restricted range of motion in the shoulder
  • Clicking or popping sensations in the shoulder joint

Treatment options for shoulder impingement may include physical therapy, anti-inflammatory medications, and modifications in activities to avoid exacerbating the symptoms. In some cases, surgical intervention may be necessary to relieve the impingement and restore normal shoulder function.

In conclusion, while clavicle fractures are common injuries that usually heal well with proper treatment, it is important to be aware of the potential complications that can arise during the healing process. Nonunion, malunion, infection, nerve damage, and shoulder impingement are some of the complications that may occur. Recognizing the signs and symptoms of these complications is crucial for timely intervention and appropriate management. If you experience any persistent or worsening symptoms after a clavicle fracture, it is important to consult a healthcare professional for further evaluation and guidance.
