Hub Cap - Modular Hand System
Introduction
The Hub Cap Limited Wrist Fusion Plate was designed to provide outstanding fixation and a straightforward technique. As a targeted solution for four-corner and other limited wrist fusions, the plate offers the kind of innovations upon which Acumed has built its reputation.
Four-corner fusions have been used with a high degree of success over the past 20 years to treat SLAC, SNAC and other arthritic conditions in the wrist. Up to seven 2.1mm or 2.7mm screws secure the plate to the Capitate, Lunate, Hamate, and Triquetrum. The screws are kept in place with the optional screw cover that threads into the center of the plate.
The Mini Hub 4-C and Mini Hub STT Limited Wrist Fusion Plates, provide all the same features that have made the Hub Cap a success: excellent screw placement, provisional stability, rounded and polished crown, grit blasted underside, screw cover, and Acumed’s advanced instrumentation.
Indications
Designed to address specific indications throughout the hand, from the carpals to the phalanges, the Modular Hand System offers the surgeon innovative fixation solutions.
Ultimately encompassing both fracture and
fusion fixation, the system is contained in a
modular tray that allows for customization
and expansion as future innovative products
are introduced.
Key Features and Benefits
– Variable screw placement is facilitated by the screw-plate interface and scalloped design that allows for maximized purchase in the four carpals. The enhanced screw placement, when combined with Acumed's 2.7mm or 2.1mm screws, makes for a solid construct that fits the patient.
– Provisional stability during insertion is achieved through both the K-Wire holes and the Plate Post. Creating this early stability ensures accurate screw placement and eliminates plate tilt, or dishing, which could lead to prominence of the plate above the dorsal surface of the carpals.
– Up to seven 2.1mm or 2.7mm screws secure the plate to the Capitate, Lunate, Hamate, and Triquetrum. These screws can in turn be locked down with the optional screw cover that threads into the center of the plate.
– Advanced instrumentation includes a dual-purpose reamer that captures and contains bone debris as it creates the spherical depression to prepare the fusion site for the Hub Cap. A unique bone graft harvester designed specifically for use on the distal radius is also included in the system.
– The Hub Cap's center hole enables using the post for provisional stability, removing it to pack bone graft, and locking of the screws with a cover - all at the surgeon's discretion.
– Scalloped holes enable placement of either 1 or 2 screws into each carpal, based on surgeon preference.
– Rounded and polished crown allows tendons to glide naturally over the top of the titanium plate, while grit blasted underside promotes bony ongrowth.
– Single hole provides a dedicated starting point that facilitates accurate placement of the remaining screws.
