Radial Head Solutions

Evidence
Publication: Fractures in Brief: Radial Head Fractures

Why This Matters
Fracture patterns of the radial head can vary greatly. Because of this reality, Acumed offers the industry’s first three-in-one solution, providing the Anatomic Radial Head replacement, the Radial Head Plating System, and the Acutrak 2 Mini and Micro instruments, all in one tray

Publication Excerpt
Acumed’s commitment to offering a comprehensive solution for radial head fractures began with the launch of the original Radial Head Plate in 2003. Three years later, the Anatomic Radial Head (ARH) launched as the first anatomically shaped radial head prosthesis on the market. The Locking Radial Head Plate launched in 2008, followed by ARH partial grit-blasted stems, designed to promote bony ongrowth, in 2011. An all-new ARH Solutions system debuted in 2014.

  • Comprehensive Solutions

    A range of solutions for simple to complex elbow fractures

  • Acutrak 2 Headless Compression Screw

    Fully threaded, continuously variable thread pitch allows each thread along the entire length of the screw to aid in the reduction and compression of the fracture.

  • Radial Head Plating System

    The system offers a straightforward solution when the radial head is salvageable. Two lengths and two head curvatures provide options for varying patient anatomy and fracture patterns.

  • Anatomic Radial Head Solutions 2

    Anatomic Radial Head Solutions 2 offers the most comprehensive implant range on the market, with standard and long stems that bring the total combinations up to 924. Enhanced instrumentation includes new height gauges, as well as resection cutting guides.

Anatomic Radial Head Solutions 2

Evidence
Publication: The Effect of Prosthetic Radial Head Geometry on the Distribution and Magnitude of Radiocapitellar Joint Contact Pressures
Why This Matters This study states that the ARH Solutions head most closely mimics the native radial head anatomy in both average and peak contact pressures. It also shows how some competitive products, most notably the Wright Medical Evolve spacer, can produce radiocapitellar pressures that may be harmful to cartilage.

Publication Excerpt
“Commercially available radial head prostheses demonstrated reduced radiocapitellar contact areas and elevated contact pressures during compressive loading. These were significantly greater with symmetrical circular prostheses than with asymmetrical elliptical designs.”

  • 924 Options. Better Precision.

    ARH Solutions 2 now has 924 head and stem combinations (from 290 with ARH Solutions), meaning more implant size choices for the physician to accommodate varying patient anatomy.

  • A Comprehensive Solution to Radial Head Fractures

    The Anatomic Radial Head Solutions 2 set offers comprehensive solutions to radial head fractures, including Acutrak 2® Headless Compression Screws, the Radial Head Plating system, and both standard and long stems for radial head replacement.

  • Long Stems for Revision Surgery

    ARH Solutions 2 offers a full range of long stems (6 mm through 12 mm, in 1 mm increments) to address revision surgeries, or for primary radial head fractures that extend more distally.

  • 2nd Generation Anatomic Head

    The dish depth increases with head diameter, which is designed to help improve radiocapitellar wear characteristics over nonanatomic heads and the first generation Acumed Anatomic Radial Head.1,2 The head’s medial surface contouring has been refined to track against the radial notch of the ulna, and to better replicate the lateral trochlear ridge facet, which may help avoid cartilage erosion.2

Elbow Plating System

Evidence
Publication: Three-Dimensional Morphometry of the Proximal Ulna: A Comparison to Currently Used Anatomically Preshaped Ulna Plates

Why This Matters
Proper reduction of the olecranon plays a crucial role in the overall stability of the elbow. This study analyzed four different manufacturers’ plates and found the Acumed plate to have the best anatomic precontouring based on their criteria.

Publication Excerpt
“Summarizing all provided features of the 4 plates, we found that plate D [the Acumed Olecranon Plate] was the most suitable plate for our elbows.

  • Industry First

    The first-to-market comprehensive, precontoured elbow plating system.

  • Olecranon Plate

    The screw trajectory is designed to allow screws to capture fracture fragments and avoid other screws regardless of the screw length selected.

  • Anatomic Curvature

    Lateral tilt in the proximal region, a distal bow throughout the ulna, and six-degree proximal ulnar dorsal angulation (PUDA) are designed to restore native patient anatomy.

  • Coronoid Plate Family

    These plates are designed to act as a buttress to the coronoid and help counteract the tendency of the elbow to subluxate.

  • Specialized Instrumentation

    Elbow-specific tools such as an osteotomy cutting jig and a distal humerus targeting guide are designed to help streamline surgeries.
