**Core Concept**
Triple arthrodesis is a surgical procedure that involves fusion of three joints in the hindfoot. It is typically performed to correct severe flatfoot deformity, degenerative joint disease, or other conditions affecting the hindfoot. The procedure involves fusion of the talonavicular, calcaneocuboid, and subtalar joints.

**Why the Correct Answer is Right**
The triple arthrodesis procedure involves fusion of these three joints to restore stability and alignment to the hindfoot. This is achieved by removing the articular cartilage and fusing the bones together using screws, plates, or bone grafts. The subtalar joint, talonavicular joint, and calcaneocuboid joint are all involved in this procedure, which helps to correct the deformity and alleviate pain. The goal of the triple arthrodesis is to restore a more normal alignment and function to the hindfoot.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the three joints involved in the triple arthrodesis procedure.
**Option B:** This option is incorrect because it does not accurately describe the procedure or the joints involved.
**Option C:** This option is incorrect because it implies that the procedure involves fusion of only two joints.

**Clinical Pearl / High-Yield Fact**
It's essential to note that triple arthrodesis is typically reserved for cases where conservative management has failed, and the patient has significant pain or deformity affecting their quality of life. The procedure can be quite complex and requires careful consideration of the patient's overall health and surgical risks.

**Correct Answer:** C.
