Cuboid bone subluxation

When the foot is exposed to microtraumas or a sudden shock, it can lead to cuboid syndrome, a subluxation of the cuboid bone. This condition frequently affects sportsmen and dancers due to the nature of their activities. Understanding the causes, symptoms, and treatments of cuboid syndrome is essential to differentiate it from other plantar conditions and to effectively manage it.

Where is the cuboid bone located?

The foot is an anatomically complex structure divided into the forefoot and rearfoot. The forefoot includes the phalanges (toe bones), while the rearfoot consists of seven tarsal bones, including the cuboid bone. Positioned midway but slightly offset to the outer side of the foot, the cuboid bone is more prone to repeated trauma due to its location.

Symptoms of a cuboid bone subluxation

Cuboid syndrome symptoms can be confused with other foot problems, making early recognition important to prevent complications. Common symptoms include:

  • Pain on the outside of the foot, especially when bearing weight;
  • Discomfort limiting movement;
  • Difficulty or inability to perform jumping and lateral movements;
  • Significant swelling on the affected foot;
  • Increased sensitivity of the foot’s sole;
  • Occurrence of stress fractures in other foot areas.

Similar foot pain

The symptoms of cuboid subluxation often resemble those of other foot injuries such as:

Thus, a podiatrist will typically conduct several diagnostic tests to exclude other pathologies and confirm cuboid syndrome.

Diagnosis

Due to the complexity of cuboid syndrome, professional evaluation by a podiatrist is necessary. Diagnostic methods may include:

These assessments allow for an accurate diagnosis and tailored treatment plan.

Cuboid syndrome causes and risk factors

The primary cause of cuboid syndrome is misalignment of the cuboid bone relative to surrounding foot bones. Injuries to the joints and ligaments near the cuboid also contribute, alongside other risk factors such as:

  • Obesity;
  • Specific plantar conditions like flat foot;
  • Excessive foot pronation during walking;
  • Sports requiring fast lateral movements (e.g., tennis);
  • Calf muscle inflexibility;
  • Running on uneven terrain;
  • Use of improper footwear;
  • Insufficient rest between sports sessions.

Cuboid subluxation prevention

Preventative measures to reduce the risk of cuboid bone subluxation include:

  • Maintaining a healthy weight;
  • Avoiding frequent running on steep or unstable surfaces;
  • Using orthopedic inserts;
  • Ensuring adequate rest after sports;
  • Wearing shoes adapted to foot size and activity.

Medical treatment for cuboid subluxation

If cuboid syndrome develops despite preventive efforts, a podiatrist can offer various treatments to relieve foot pain, such as:
