PROMO or Proximal Rotational Metatarsal Osteotomy is a hallux valgus correction system designed to allow complete bunion correction in multiple planes. Recent studies have shown that up to 87% of hallux valgus (bunion) deformities contain a frontal plane rotational deformity.1  While traditional single-plane procedures such as the scarf or chevron osteotomes only correct the transverse deformity, PROMO simultaneously corrects the metatarsal internal pronation as well as the varus deformity through a single, oblique osteotomy.

The patent-pending PROMO System contains a series of custom jigs and implants utilized in the measurement, construction and fixation of an oblique plane osteotomy specific to the patient’s deformity. Unique plates are included that are 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.

Features & Benefits:

  • Corrects all deformity parameters including rotation in the frontal plane. May help decrease chance of recurrence2
  • Single Oblique Osteotomy. Reduces the likelihood of shortening which can help prevent transfer metatarsalgia. Osteotomy allows for placement of an interfragmentary screw which increases the rigidity of the construct
  • Custom jigs aid in construction of the oblique plane osteotomy. Repeatable and streamlined technique
  • Avoids fusing the first TMT joint. Helps sustain patient joint health
