Abstract:
Treatment of rigid claw toe is still subject to discussion and evolution. Arthrodesis or arthroplasty of the PIPJ is apparently the most reliable procedure. K wire seems be the most reliable way to solve this clinical issue, but different implants specifically created to treat PIPJ deformities are being developed, and still have to be tested clinically. The use of screws to fix the PIPJ is a valid alternative, although some problems remain to be solved, specifically pain in relation to the tip of the screw. Longer follow-up studies are needed to increase our knowledge of the treatment of this specific deformity.

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
