Surgical Site Preparation / Incision /
Preparation of the Joint Surfaces

As the distributor of this device, Integra Lifesciences Corporation does not practice
medicine and does not recommend this or any other surgical technique for use on a
specific patient. The surgeon who performs any implant procedure is responsible for
determining and using the appropriate techniques for implanting the device in each patient.

Surgical Site Preparation

The foot is prepped and draped following normal sterile technique
The surgery is done under tourniquet to avoid bleeding

Incision

A dorsal longitudinal incision is commonly used. This enables correct exposure of the
metatarsophalangeal joint.
The incision is centered just medial to the extensor hallucis longus, and deepened to the
joint capsule, through the subcutaneous tissues
The joint capsule is released and retractors are placed to expose the base of the proximal
phalanx and metatarsal head

Preparation of the Joint Surfaces

The amount of the bone resection depends upon the desired length of the 1st metatarsal. (Note: some revision cases will not require extensive resection.)
A power saw may be used to resect the base of the proximal phalanx and the articular surface of the 1st metatarsal head
A cut, resecting a small wafer of bone, perpendicular to the axis of the proximal phalanx is made just distal to the articular surface. A similar cut is made in the metatarsal head perpendicular to the long axis of the metatarsal shaft (figure 1).
These cuts are made in order to decompress the joint, allowing the use of the reamers. Osteophytes should be carefully removed. Medial exostosis of the 1st metatarsal bone may also be resected.
