Your Metatarsophalangeal joint (MTP) connects your phalanges (bones of the toes) to the longer metatarsal bones in your foot. This joint forms the ball of the foot. Deformities of the lesser toes (all but the big toe), can cause the MTP joint to become unstable, causing the second toe to either cross over the big toe or push against the third toe in a sweeping effect. Either of these situations can result in a condition known as hammertoe, one of the most common deformities. Hammertoe causes difficulty and pain in walking and can cause the joint to stiffen if left untreated.
If your MTP joint requires surgical intervention, the HAT-TRICK MTP Joint Repair System offers a state-of-the art approach to treatment that may help reduce some complications common in standard toe surgery:
The HAT-TRICK MTP Joint Repair System provides a complete repair of the lesser MTP joint that is less invasive and more anatomically correct than current surgical standard of care techniques.
Traditional MTP surgery requires a metatarsal osteotomy. This means bone (“osteo”) removal (“otomy”) in order to shorten the metatarsal bone and re-align your toe. The bone removal is held in place with screws and wires that cause additional pain and discomfort during the healing process. Complications from this surgery range from stiffness and pain to floating toe, where the ligaments contract and bend your toe upward.3
The HAT-TRICK MTP Joint Repair uses special instruments and techniques to reattach ligaments and bones in their proper alignment without removing bone, avoiding permanent bone modification and unnecessary ligament and joint cutting.4
