OSferion is an osteoconductive bone graft substitute and bone void filler consisting of 100% High Purity Beta-Tricalcium Phosphate (β-TCP). OSferion's micro and macro porous structure allows it to be resorbed and replaced by bone during the healing process when used in conjunction with rigid fixation devices. These revolutionary osteotomy wedges have an unprecedented compressive force of 15-20 MPa (2900 pounds/square inch), comparable to cortical bone, adding improved stability to the correction site. OSferion wedges can be used in conjunction with the Arthrex distal femoral and high tibial opening wedge osteotomy plates and screws. The chamfered wedge design of the implants corresponds to the shape of the open wedge correction performed with the Opening Wedge Osteotomy System. After insertion of the osteotomy plate, the appropriate size OSferion wedges are prepared in a sterile fashion using autogenous blood, or osteotomy site bone marrow and placed within the osteotomy site by hand. The OSferion wedges are placed on either side of the secured osteotomy plate within the osteotomy. They can be trimmed to size using a rongeur.

The ContourLock HTO Plate® System is indicated for use as a fixation device during opening and closing wedge osteotomies of the proximal tibia. This next generation titanium plating system consists of three distinct plate variations, including a straight wedge, A/P sloped wedge and a flat plate with no wedge, that are compatible with the current titanium cortical and cancellous HTO Plate Screws. As the result of an improved locking bushing system, each of the screws lock tightly into the plate bushings without having to use the Locking Guide for Titanium HTO Plates, further simplifying the plate and screw insertion process. This plating system will be the focus of ongoing clinical studies that evaluate its potential for early weight-bearing postoperatively.

Titanium
Anatomically curved and low profile, ContourLock DFO plates are available in right and left orientations and multiple sizes, depending on the desired amount of correction. The toothless design facilitates greater flexibility through infinite correction potential up to 20 mm without compromising strength.
Titanium Femoral Opening Wedge Osteotomy Plates provide a straight-toothed option to aid in maintaining the osteotomy correction.
These plates are fixated to bone using titanium locking 6.5 mm cancellous and 4.5 mm cortical screws. Each screw can be angled to the proper anatomic orientation within a swiveling bushing before being locked.
Stainless Steel
Low-profile, stainless steel Femoral Opening Wedge Osteotomy Plates are available with a straight tooth to facilitate maintaining the osteotomy. These plates are optimal for unique anatomy that requires a customized fit with multiple bends. The plates are fixated using standard AO stainless steel 6.5 mm cancellous and 4.5 cortical screws.
All of the Femoral Opening Wedge Osteotomy Plates are designed to work in conjunction with the standard <a href="http://www.arthrex.com/knee/opening-wedge-osteotomy-instrument-set">Opening Wedge Osteotomy Instruments Sets.</a>

ContourLock™ Distal Femoral Osteotomy (DFO) Plates and Screws

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.

The Two-Hole Osteotomy Support Plate Implant System includes an anatomically contoured two-hole titanium plate and two 4 mm x 30 mm titanium self-tapping cancellous screws. It is indicated for fixation following proximal tibial or distal femoral opening and closing wedge osteotomies. These non-locking screws fit snugly into the plate in a recessed fashion to create a low profile construct, when inserted using a standard 2.5 mm hex driver. The two-hole plate is the perfect option for supporting a fractured lateral tibial cortex during HTO procedures, as well as supporting the anteromedial tibial cortex during slope changing HTO procedures. The plate has a built-in offset hole to accept small K-wires to facilitate positioning it over the osteotomy site. The plate can be slightly bent to conform to variations in bony anatomy easily using Universal Bending Irons from the Opening Wedge Osteotomy System Set.
