Pes cavus (high arch) is when the sole of the foot is distinctly hollow when bearing weight. Pes cavus is often a sequela of lower extremity nerve disorders from neurologic disease or stroke. Often patients will have foot drop and an equinus deformity. Treatment consists of tendon transfers and bony structural changes to form a stable plantigrade foot for weightbearing.
Arthrex has developed a comprehensive line of products from the EndoBlade™ system to treat equinus deformity, tendon transfers with Tenodesis screws and InternalBrace™ ligament augmentation, multiple diameters of Headless Compression FT and PT Screws, BioSync® wedges for Cotton/Evans osteotomies, and an extensive line of plates and screws in the Comprehensive Foot System.

Procedure

The titanium Compression FT (fully threaded) screws come in 2.5 mm Micro, 3.5 mm Mini, 4.0 mm Standard, 5.0 mm Large, and 7.0 mm XL. The variable-stepped thread pitch and headless design helps reduce the risk of profile complications, provides compression, and allows for simplified insertion. Surgeons can now achieve zero-profile, stable fixation. The Compression FT family of screws now offers 5 diameters and 91 screw lengths to fit various orthopedic applications throughout the body.

Arthrex offers a multitude of fixation options for 1st metatarsal osteotomy corrections. For surgeons that prefer a minimally invasive approach, Arthrex offers a comprehensive product line for percutaneous osteotomies and fixation with Compression FT screws.
For surgeons that prefer a traditional plating approach, Arthrex offers the versatile proximal 1st metatarsal osteotomy plate. Ludloff, Mau, proximal, crescentic, proximal Chevron, and Scarf osteotomies can all be fixated using the same plate. Arthrex also offers proximal opening wedge osteotomy plates to reduce the IM angle.

First Metatarsal Osteotomy

Arthrex offers the TenodesisScrew System in order to treat patients with a dysfunction of the posteriortibial tendon, where the tendon is stretched beyond its functional length, isdiseased or has ruptured. As a result,the FDL tendon is transferred into a bone tunnel into the navicular and fixatedwith a screw from the Bio-Tenodesis System.

Flexor Digitorum Longus Tendon Transfer With DX Button and Tension-Slide Technique

The FDL Implant System comes in two size offerings of 4.75 mm × 15 mm and 5.5 mm × 15 mm with everything included for an FDL tendon transfer in association with the tension-slide technique. The addition of the Spring Ligament InternalBrace™ procedure completes this simple and reproducible method of fixation that reliably seats the tendon against the cortex of the bone socket, maximizing the surface area for tendon-to-bone healing as well as augmenting the repair of the superior and inferior band of the spring ligament complex.
The InternalBrace surgical technique is intended only to augment the primary repair/reconstruction by expanding the area of tissue approximation during the healing period and is not intended as a replacement for the native ligament. The InternalBrace technique is for use during soft tissue-to-bone fixation procedures and is not cleared for bone-to-bone fixation.
