What is Cuboid Syndrome or Cuboid Subluxation?
There are 7 tarsal bones present in the rear and mid-foot and one of them is the cuboid bone. Cuboid syndrome (cuboid subluxation) is a condition which occurs after an injury to the joints and ligaments present near the cuboid bone. This condition often occurs with peroneal tendinopathy or after a major ankle inversion sprain. It can also occur independently. The calcaneocuboid joint becomes partially dislocated, i.e. between the heel bone (calcaneus) and the cuboid present anteriorly. Treatment comprises of physically manipulating the displaced joint back into position by a physician.
Symptoms of Cuboid Syndrome or Cuboid Subluxation
- Pain and weakness in the foot.
- Pain upon weight bearing.
- Worsening pain when the whole body weight is shifted to the affected foot.
- There may be significant overpronation of the foot.
- Swelling may be present.
- Pain may develop gradually. It may sometimes subside completely and then start again.
Causes of Cuboid Syndrome or Cuboid Subluxation
- Trauma or injury to the foot.
- Stress to the foot over time.
- Sports persons or athletes are commonly affected by this as they are involved in activities which put a lot of pressure on their feet such as jumping or running.
- If the patient has pre-existing overpronation or underpronation of the foot, then the risk for injury and developing this condition increases.
Treatment of Cuboid Syndrome or Cuboid Subluxation
- Patient should seek medical consultation immediately.
- The physician will physically reduce the cuboid bone back into its normal position.
- The foot can be taped to maintain the aligned position.
- Proper foot wear should be used.
- A cuboid pad can also be used to maintain the joint position.
- Ice therapy can be used to reduce any swelling.
- Pain killers can be given for pain relief.
- Arch support insoles can be used to keep the joint in position.
- If the cause is peroneal tendonitis, then this should be treated.
- Corticosteroid injections can be given for pain relief.
