The HARMONY® System builds on more than 25 years of clinical experience (1) of the cementless self-locking stem concept and is the universal choice for primary total hip arthroplasty.

Proven design

Horizontal grooves to provide axial stability.

Proximal and distal quadrangular sections designed to promote initial implant stability.

radio_button_checked

Refined anterior-posterior neck geometry designed to maximize range of motion and reduce the risk of “impingement” between the neck and cup.

Progressive anteroposterior tuliping in the metaphyseal zone designed to provide load transfer and promote osseointegration in the proximal femur.

Full-length hydroxyapatite coating to promote osseointegration and cementless secondary fixation of the implant.

Simple and flexible system

according to indications

Osteotomy level to facilitate identification of the level of blockage.

Slotted impaction hole to allow for rotational guidance of the stem during impaction and for retention during the cementing phase.

Mirror polished surface to optimize the stem/cement interface and limit the amount of wear particles.

radio_button_checked

Simple and flexible system according to indications

  • Simple and reproducible operating technique
  • Choice of several stem options to meet a wide variety of indications
  • Choice among several types of cutter holders depending on the approach
  • Simple instrumentation common to all stems in the system
