Features

  • Comprehensive Plating System

    Standard, Variable Angle Locking, Fragment Specific and Extension Plates address a variety of fracture patterns.

  • Fracture Support

    The distal screw row is designed for subchondral support, while the two styloid screws target the radial column. Suture holes on the ulnar corner of the plate and an optional hook plate facilitate fixation of volar rim fractures.

  • Frag-Loc® Technology

    Patented two-part cannulated compression screw is designed to compress dorsal fragments and integrates with the optional avulsion hook plate for a dorsal approach to marginal rim fracture fixation.

  • Instrumentation

    Innovative instrumentation includes a targeting guide with radiopaque markings that allow visualization of anticipated screw trajectories. Kickstand posts are offered for distal first reduction and corrective osteotomy procedures.

  • Modular Extension Plate Attachments

    Offer surgeons the option to extend any of the long and wide Volar Distal Radius Proximal Plates up to 176 mm.

Distal Radius Fragment Specific (DRFS) Plates

Acumed Distal Radius Fragment Specific (DRFS) Plates are designed to independently address the fractures of the intermediate and radial columns. The modular nature of the plates, which include the Dorsal Rim Buttress Plate, Dorsal Lunate Plate, Volar Lunate Suture Plate, and Divergent Radial Styloid Plate, allows compression of fracture fragments from multiple directions.

DRFS Plates
Image

The Divergent Radial Styloid Plate buttresses the radial column. Targeted distal screw placement is designed to provide subchondral bone support, with one screw targeting the dorsal rim of the sigmoid notch and the other targeting the volar rim. In addition, fixed-angle screw trajectories are designed to avoid the sigmoid fossa, minimizing penetration of the distal radioulnar joint.

Image

The Dorsal Lunate Plate is designed to provide support to fracture patterns that involve the dorsal lunate facet of the distal radius and the sigmoid notch. The Dorsal Lunate Plate can be inserted through a smaller incision than a standard dorsal approach. For added stability, three plate screws are designed to target the subchondral bone and support the lunate facet.

Image

The Dorsal Rim Buttress Plate, designed for distal radius fractures, is positioned on the dorsal ulnar side of the radius. The plate extends radially to support dorsal lip comminution and buttress dorsal fragments. Three screws are designed to target the subchondral bone and support the lunate facet, while a screw can be inserted ulnar-to-radial for further radial styloid support.

Image

The Volar Lunate Suture Plate supports the volar ulnar corner of the distal radius. Built-in suture holes allow for sutures to be used with the plate to capture small articular fragments. Distal plate placement may maximize volar ulnar lip support, while three screws target the subchondral bone to support the lunate facet.

Standard Volar Distal Radius Plates

Standard Volar Distal Radius Plates

Acumed Acu-Loc 2 Standard Volar Distal Radius Plates have an optimized design to closely replicate the anatomical contours of the distal radius and assist in restoring its natural geometry.

Other optimized features include a lower profile, polished finish which may help minimize soft tissue irritation, and converging ulnar screws, additional suture holes, and added K-wire holes for provisional fixation.

Avulsion Hook Plate (Optional)

Standard Volar Distal Radius Plates

The Acumed Avulsion Hook Plate is designed to provide more stability than a K-wire when a fragment is too small for a single lag screw. When used with the Standard Volar Distal Radius Plate, the ultra-thin 0.8 mm Avulsion Hook Plate offers extended fixation and articular buttress for marginal rim fractures via either volar or dorsal surgical approaches.

Proximal Volar Distal Radius (VDR) Plates

Proximal Volar Distal Radius Plates

The Acumed Acu-Loc 2 Proximal Volar Distal Radius (VDR) Plates are designed for distal radius fracture and osteotomies, as well as segmented diaphyseal fractures. Customizable plate length and width options allow for sizing of varying patient anatomies.

In addition, converging ulnar screws, suture holes, and K-wire holes have been incorporated to support the volar ulnar lip and lunate facet. The 2.3 mm Variable Angle screws can also be used with this plate family.

Extension Plates

Extension Plates

Acumed Acu-Loc 2 Extension Plates are designed to lock to Acu-Loc 2 Proximal VDR Plates to provide rigid fixation of segmental fractures of the distal radius that extend into the diaphyseal region. The proximal plate end is tapered and the undersurface is designed for limited contact with the bone.

Frag-Loc Compression Screw

The Frag-Loc Compression Screw is a two-part cannulated compression screw for dorsal comminution that gives surgeons the option for steadfast dorsal compression through a small dorsal incision. In addition, the undersurface geometry of the screw head allows for sub-osseous purchase into the dorsal fragment while designed for minimizing hardware prominence.

Variable Angle Locking Screws

Extension Plates

Acumed Variable Angle Locking Screws can aid in the capture of specific fragments or accommodate variations in patient anatomy. They can be used in any distal hole of any of the gold colored Acu-Loc 2 Proximal VDR Plates or Acu-Loc Extra Articular Plates. The screws allow for a total variance of 5 mm or 15 degrees.

2.7 mm Low-Profile Hexalobe Screws

Extension Plates

Single Drill for Surgical Efficiency: When plating the distal radius and ulna, the 2.7 mm Low-Profile Hexalobe Screw and the 2.3 mm screws that are used for fixation both use the 2.0 mm Quick-Release Drill.

Reduced insertion torque for easier advancement: 2.7 mm Low-Profile Hexalobe Screws have a 58.5% reduction in insertion torque compared to 2.7 mm Hexalobe Screws.*

Tailored to your patient’s needs: A smaller diameter screw is designed to address fractures in smaller bones or smaller-stature patients.
