Our 17-gauge needle, once inserted into the joint, accepts the 1.19 mm Nitinol wire for quick and easy joint access. The OSI Introducer Needle has been passed through the reverse compression screw of the Hip Tool. Significantly more bone marrow is delivered to the cancellous bone graft stabilized by the 125-degree Hip Tool.
The smooth 3.2 mm guidewire is designed for blunt tip insertion into the joint, completely avoiding the need for traditionally sharp or large diameter trocars. OSI dilators dilate the soft tissue in 5.4 mm, 6.5 mm, and 8.5 mm diameters.
The threaded tip guidewire is designed for its strategic placement within the femoral head, humeral head, or femoral condyles during core decompression. The OSI Coring Trephine symmetrically circumscribes the guidewire creating a core sample for later histopathologic analysis when necessary. Inquire about our additional core decompression products that facilitate endoscopic evaluation of the core track. See our White Paper, The Effects of Oxidized Low-Density Lipoproteins on the Pathogenesis of Osteoarthritis and Avascular Necrosis.
In the image below, precise core decompression using the OSI Bone Coring Trephine and 3.2 mm threaded guidewire is demonstrated. A substantially undisturbed column of bone can be sent to pathology, while that bone more laterally situated can be returned to the femoral head. OSI's core decompression system does not ream away the antecedent bone and is the only system that affords this degree of surgical control.
The smooth tip guidewire is designed for lateral wall portal establishment during the treatment of bone marrow edema lesions in patients with subchondral lesions and the Biomass Delivery Curette will be used for graft delivery.
The Nitinol wire is freely passed through the Introducer Needle to facilitate arthroscopic shaver insertion and portal retention.
The Teardrop Probe is designed for safely sounding the depth of bone and marrow harvesting sites when using the Beacon Biomass Harvesting Trephine.
