An alterative to traditional metal plates and screws, the iBalance HTO system consists of nonabsorbable polyetheretherketone (PEEK) implant anchors that are inserted into the proximal tibial opening wedge osteotomy site during HTO procedures to maintain and fixate the osteotomy. The iBalance HTO implants and anchors are intended for permanent implantation and, in some cases, may negate the need for a second surgical procedure to remove hardware due to overlying soft-tissue irritation.
To promote healing and provide additional strength to the repair, biologics such as OSferion osteotomy wedge, Quickset™* cement, AlloSync™ demineralized bone matrix, and autologous conditioned plasma may be used.

Procedure

Using iBalance implants and instrument system to create a safety envelope with locked-in retractors, the iBalance HTO surgical technique builds confidence and familiarity with a step-by-step guide for creating safe, reproducible cuts. The technique significantly reduces the chances of neurovascular injury and lateral hinge fractures,1 and the instruments help align the osteotomy to the sagittal and coronal planes, thus preserving the tibial slope.

iBalance® HTO Surgical Technique

After determining the angle of correction preoperatively, the medial exposure of the tibia is established and the anterior, medial, and posterior soft tissues are safely elevated. The tibial osteotomy then begins by placing the Arthrex® HTO Cutting Guide on the medial tibia and drilling two 2.4 mm guide pins to within approximately 1 cm of the lateral cortex under fluoroscopy control. The surgeon may also choose to use the Arthrex Biplanar Alignment Guide to set the height and align the osteotomy with the patient's native tibial slope. Once the desired Arthrex Cutting Guide and retractors are in place, the osteotomy is completed utilizing an osteotome or specific saw blade. The osteotomy is then opened to the desired amount of correction via the Arthrex iBalance® HTO Opening Jack, Osteotome Jack or Osteotomy Wedge.
