beforeandafterPIPThe Proximal Interphalangeal Joint, or PIP Joint, is the second joint of your lesser toes. Hammertoe and claw toe conditions can cause this joint to become fixed and unable to straighten. This is a gradual deformity and cannot be straightened by any means other than surgery.

The surgery required to straighten your toes typically involves removal of bone portions through an incision on top of your toe. The bone removal allows your toe to be straightened. Once straightened, a long wire known as a K-wire is pushed through the front of your toe, with a portion sticking out of the end of your toe. This wire helps keep your toe in a fixed position for four to six weeks, and is then removed.

These types of surgery have multiple issues with pain and fusion, and 10 to 46 percent of patients are dissatisfied post-surgery. 1

The complications of a K-wire type of surgery are many and include2:

Less Invasive

The HAT-TRICK PIP Fusion system provides an alternative to wires sticking out of your toes. The HAT-TRICK PIP Fusion system consists of a device known as a PEEK (polyetheretherketone) implant, which is a technology that has been used in orthopaedic and spine procedures for many years. The PEEK implant is radiolucent, which allows your surgeon – and you – to see the fusion progress on an x-ray. By contrast, metal implants such as wires and screws appear solid on an x-ray and do not always allow a full view of your healing. The HAT-TRICK PIP Fusion system also provides your surgeon with a technology designed to achieve a better fusion and, ultimately, a less invasive healing process

The surgery involves an incision to gain access to the joint and minimal bone removal. Your surgeon will implant the HAT-TRICK PIP device into your toe with half in the middle phalanx and half in the proximal phalanx. This unique compression technology is exclusive to the HAT-TRICK PIP Fusion System and holds your toe in place, allowing full fusion to occur.

Anatomically Correct

The HAT-TRICK PIP device is available as a straight, or 10-degree curve implant, to return your toes to their anatomically correct position. Based on your condition, your surgeon will ultimately determine if a 0° or a 10° is most appropriate for you.
