3S HEMI TOE IMPLANT SYSTEM The 3S Hemi Implant System consists of a cobalt chromium (CoCrMo) implant to replace the articulating surface of the proximal phalanx of the first metatarsophalangeal joint and corresponding instrumentation to facilitate insertion. • Radiused, low profile anatomical head shape to allow for natural articulation and to provide the option of preserving host bone • Tri-spade stem design intended to maximize stability and bone-to-implant contact for optimal osteointegration • Sharp chisel-tip stem for simple initiation and placement • Simple surgical technique for reduced OR

3S HEMI IMPLANT SYSTEM SURGICAL TECHNIQUE STEP 1: Expose the 1st metatarsal phalangeal joint with a 4cm to 5cm slightly curved dorsal incision just medial to the EHL tendon, allowing proper dissection to expose the joint capsule. STEP 2: Retract the tissues, then incise the capsule with a “T” incision at the MPJ for exposure of the phalangeal base and the metatarsal head. Carefully release the capsular structures from the medial, dorsal, and anteriolateral aspects of the joint. STEP 3: Resect the articular surface of phalanx with an oscillating or sagittal saw, making the cut perpendicular to...
