Arc Wrist Tower

Publication: Arthroscopic Management of Scapholunate Instability

Why This Matters

Wrist arthroscopy plays a valuable role in the management of scapholunate instability. A spectrum of injuries can occur to the scapholunate interosseous ligament, which may be di”cult to detect with imaging studies. Wrist arthroscopy enables detection and management of injury to the scapholunate ligament under bright light and magnified conditions, in both acute and chronic situations.

Publication Excerpt
“Once the K-wires are placed into the scaphoid, the wrist is then resuspended in the traction tower. The arthroscope is then placed in the MCU portal. This allows the surgeon to look across the wrist to better judge the rotation and reduction of the scapholunate interval as the K-wires are advanced.”
Geissler WB. Arthroscopic management of scapholunate instability. J Wrist Surg. 2013;2(2):129-135.
  • For Wrist Arthroplasty and Fracture Reduction

Total Wrist Fusion Plating System

Publication: Total Wrist Fusion: A Functional Assessment

Why This Matters

Wrist arthrodesis significantly alters wrist function, but is an option for patients with unremitting wrist pain. Acumed’s Total Wrist Fusion plates place the wrist in 15 degrees of extension and 0–10 degrees of ulnar deviation, a position that is intended as a balance between anatomic resting position, hand function, and grip strength.

Publication Excerpt

“The number of operations performed prior to the wrist total fusion (seven of these being unsuccessful limited wrist fusion after treatment for scaphoid non-union) is interesting. It may be that total wrist fusion should be performed earlier for these problems rather than limited carpal arthrodesis, which will inevitably result in total arthrodesis at a later date.”

“Pryce (1980), in a very complete study, showed better grip strength both in 15° extension and 15° ulnar deviation, than in neutral in both planes.”

1. Field J, Herbert TJ, Prosser R. Total wrist fusion: a functional assessment. J Hand Surg Am. 1996;21(4):429–433.
  • Approach-Specific Plate Options

    The system oers left and right specific plates as well as a neutral plate. All plates have a 15-degree bend that is intended to maximize grip strength.1

  • Second Metacarpal

    The system includes four plates designed specifically for second metacarpal placement to avoid tendon irritation.

  • Ulnar Deviation

    Second metacarpal plate placement puts the wrist into ulnar deviation. This is intended to allow better grip strength.1

  • Converging Screw Design

    The plates’ converging distal screw design is intended to assist with pullout resistance.

  • Neutral Plate Option

    The Neutral Plate was designed to be used with a proximal row carpectomy.

Anatomic Midshaft Forearm Plating System

Publication: Radius Morphology and Its Effects on Rotation With Contoured and Noncontoured Plating of the Proximal Radius

Why This Matters

The Anatomic Midshaft Forearm Plating System allows surgeons to restore the natural curvature of the proximal radius through the application of a precontoured plate. Restoration of native geometry is crucial to reestablishing patient range of motion and overall forearm pronation and supination.

Publication Excerpt
“This study has shown a significant sagittal bow of the proximal shaft of the radius. Plating this with contoured plates in the sagittal plane improves rotation when compared with straight plates. Additional ulna plating is not a source of reduced forearm rotation.”
1. Rupasinghe SL, Poon PC. Radius morphology and its effects on rotation with contoured and noncontoured plating of the proximal radius. J Shoulder Elbow Surg. 2012 May;21(5):568-573.
  • The First Precontoured Radius Plates

    Due to the sagittal bow of the radius, plating with contoured plates in the sagittal plane improves rotation when compared with straight plates.1 For every 5 degrees of radial curvature that is not restored, the patient may lose 15 degrees of rotational motion.1

  • Three Plate Options

    Acumed oers two contoured radius plate options, including volar and dorsolateral approach options and an ulna plate.

  • Precontoured Plate Advantages

    Precontoured plates are intended to minimize the need for intraoperative plate bending to help save operating time. This allows surgeons to focus on restoring anatomy and re-establishing forearm pronation-supination.1

  • Creative Instrumentation

    Innovative instrumentation includes a swiveling plate clamp, an angled drill guide, and a soft tissue spreader to aid in plate implantation. An oset drill guide enables dynamic compressive drilling for additional compression across the fracture site.

Ulna Rod

Publication: Interlocking Contoured Intramedullary Nail Fixation for Selected Diaphyseal Fractures of the Forearm in Adults

Why This Matters

The advantages of an interlocking intramedullary nail system are that it is technically straightforward, it allows a high rate of osseous consolidation, and it requires less surgical exposure and operative time than plate osteosynthesis.

Publication Excerpt
“It [IM fixation] results in a union rate comparable with that following plate fixation. In addition, it requires no periosteal stripping and the incisions are smaller than those required for plate fixation, making the technique particularly appealing when the overlying soft-tissue envelope is tenuous.”
Lee YH, Lee SK, Chung MS, Baek GH, Gong HS, Kim KH. Interlocking contoured intramedullary nail fixation for selected diaphyseal fractures of the forearm in adults. J Bone Joint Surg Am. 2008;90:1891–1898.
  • Minimally Invasive

    The rod is designed to be inserted through a small incision with minimal canal reaming.

  • Rotational Stability

    The rod’s paddle-blade tip and interlocking screws are designed to lock and rotationally secure bone segments to assist in fracture union.

  • Straightforward Technique

    The straightforward surgical technique is designed to streamline the surgical experience.

  • Precontoured Rods

Osteotomy System

Publication: A Study Comparing the Outcomes of Transverse Ulnar Shortening Osteotomy Fixed With a DCP to Oblique Osteotomy Fixed with a Procedure Specific Plate

Why This Matters

Ulna shortening osteotomies performed with Acumed’s system had a significantly lower hardware removal rate (3.3%) compared to transverse osteotomies (16.6%) and demonstrated a shorter duration for radiological healing.

Publication Excerpt
“The rationale being that the TO [Transverse Ostetomy] involves making bony cuts freehand and must be perfectly parallel to each other. The OO [Oblique Osteotomy] made using a dedicated instrumentation system allows a reliable technique for the bony cuts. Theoretically, the OO may provide more surface area for bone healing and better union rate than the TO.”
Singhal R, et al. A study comparing the outcomes of transverse ulnar shortening osteotomy fixed with a DCP to oblique osteotomy fixed with a procedure specific plate. J Hand Surg Asian Pac. Vol. 2020 Dec;25(4):441-446.
  • A Streamlined Approach

    Featuring the industry’s first adjustable cutting guide, the Acumed Osteotomy system helped simplify the ulnar shortening osteotomy, by eliminating the need for numerous cutting jigs.

  • Osteotomy Compression

    The reduction clamp’s speed-lock wheel is designed to help maintain hands-free compression, while the temporary reduction peg is engineered to stabilize the ulna during the osteotomy and assist with osteotomy compression.

  • Cutting Guide

    The cutting guide oers continuous adjustment from 1 to 10 mm, allowing a resection of the amount desired.

  • Reference Lines

    The reference lines on the Ulnar Shortening Plate spaced 2 mm apart, help facilitate the creation of the osteotomy when a “freehand cut” is preferred.
