Calcaneal Osteotomy for Flatfoot
A calcaneal osteotomy is a common technique used to treat stage II flatfoot deformity. Arthrex's recently launched Minimally Invasive Surgery platform allows surgeons to perform this osteotomy through a tiny incision. Surgeons can then achieve fixation using the 7.0 mm Compression FT screws or the 6.5 Compression PT screws.
Compression FT Screws Technique
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 surgeons an array of fixation options for the Cotton osteotomy. The titanium porous BioSync® wedges offer a zero-profile, stable construct, designed to exactly match the anatomy of the cuneiform. For surgeons who prefer allograft wedges, Arthrex also offers precontoured allograft AlloSync™ wedges designed with the same anatomical shapes and sizes as the BioSync family of products.
FDL Tendon Transfer
FDL tendon transfer is used for posterior tibial tendon dysfunction. Arthrex has developed the Tenodesis Tension-Slide Technique for FDL tendon transfer. The flexor digitorum longus tendon is traced to the master knot of Henry and harvested. It is then transferred to the navicular and stabilized with the DX button on the dorsal cortex as well as a Tenodesis screw for aperture fixation. This procedure can be done in conjunction with the InternalBrace™ augmentation repair of the spring ligament.
Lateral Column Lengthening (Evans Osteotomy)
Arthrex offers multiple implant options for lateral column lengthening procedures including the BioSync® titanium porous wedges or the AlloSync™ allograft wedges. Both products are available in several shapes and sizes, allowing surgeons to choose between a permanent structural implant or an allograft implant.
The ProStop arthroereisis subtalar implant is intended to assist in treating the hyperpronated foot by stabilizing the subtalar joint. It is intended to block forward, downward, and medial displacement of the talus, thereby limiting excessive eversion of the hindfoot. The conical shape of the ProStop mimics tarsal canal anatomy for improved fit and resistance to implant migration, while the soft thread design supports better implant-to-bone contact.
