Astragalectomy

Astragalectomy is a surgical procedure involving the removal of the talus bone (astragalus) from the ankle joint. This procedure is typically performed to address severe deformities, infections, or trauma that cannot be managed through other surgical methods.

Indications

Astragalectomy is indicated in cases where there is:

• Severe arthritis of the ankle joint
• Irreparable damage to the talus bone due to trauma
• Chronic osteomyelitis (bone infection) of the talus
• Severe deformities such as clubfoot that are unresponsive to other treatments

Procedure

The procedure involves the following steps:

1. An incision is made over the ankle joint to expose the talus bone.
2. The talus bone is carefully dissected and removed.
3. The remaining bones, including the tibia and calcaneus, are realigned and fused together if necessary.
4. The incision is closed, and the ankle is immobilized to allow for healing.

Postoperative Care

Postoperative care includes:

• Immobilization of the ankle using a cast or brace
• Physical therapy to restore mobility and strength
• Pain management with medications
• Regular follow-up visits to monitor healing and detect any complications

Complications

Potential complications of astragalectomy include:

• Infection
• Nonunion or malunion of the bones
• Loss of ankle mobility
• Chronic pain

Outcomes

The outcomes of astragalectomy can vary depending on the underlying condition and the patient's overall health. Many patients experience significant pain relief and improved function, although some may have residual stiffness or limited mobility in the ankle joint.
