The patent-pending PROMO Tri-planar Hallux Valgus System contains a series of custom jigs and implants designed to measure, construct and fixate an osteotomy on the proximal aspect of the first metatarsal. The osteotomy created is oblique and patient specific depending on the severity of IM angle and rotation angle. The oblique cut allows rotation of the distal aspect of the metatarsal to simultaneously correct metatarsal internal rotation and varus deformity with no wedge resection.
The PROMO system comes equipped with specific PROMO plates sized and shaped around the oblique angulation of the osteotomy. PROMO also includes a PRECISION™ guided system which enables the user to place a cross screw across the osteotomy while avoiding hardware collision with the plating construct.
