The Acumed Hand Fracture System is designed to surgically treat various metacarpal and phalangeal fractures, fusions, and osteotomies and includes five solutions in one tray. Versatile screws, customizable plates, and dedicated instrumentation offer a comprehensive system to streamline the surgical experience. The system features precontoured standard plates, specialty plates, and Hexalobe MultiScrews. Hexalobe Lag Screws and threaded K-wires are also included for less complicated fractures. The Acumed Small Bone Fixator and Small Bone Distractor provide external fixation options.
The system includes customizable Locking Plates, Small Bone External Fixator, Small Bone Distractor, partially threaded lag screws, and Hexalobe Multiscrews that act as both a nonlocking and variable angle locking screw in one.
Rolando Fracture Hook, Metacarpal Neck Fracture, Avulsion Hook, Curved Medial/Lateral and Rotational Correction plates.
Versatile Screw-and-Plate System
The system was the first in the industry to allow multiple Hand Fracture System screw diameters in every hole of every plate in the system.
Specialized instruments in the system include an osteotomy cutting guide, the SaveLoc compression sleeve, unique clamps and forceps, and a plate cutter.
The Hand Fracture System Plate Family
The 0.8 mm Avulsion Hook Plate is designed to provide more stability than a K-wire when a fragment is too small for a single lag screw. The prongs in the 0.8 mm Avulsion Hook Plate are used to support an avulsion fragment when the avulsed fragment is too small for a lag screw and more stability is desired than pinning with K-wires alone can provide. This can often occur at the insertion of the collateral ligaments in the proximal phalanges.
The 1.3 mm Rolando Fracture Hook Plate is designed for a three-part fracture pattern at the base of the first metacarpal. The prongs on the proximal end of the 1.3 mm Rolando Fracture Hook Plate should contact the dorsal surface of the abductor pollicis longus (APL) tendon and support any comminution of the base of the first metacarpal. These prongs are not intended to compress the APL tendon down to the bone and a gap may be visible between the plate prongs and the bone on X-ray.
The 1.3 mm Metacarpal Neck Plate is designed to provide fixation for metacarpal neck fractures. The plate is positioned dorso-laterally. If a medial placement is preferred, the plate opposite to the hand may be used, i.e., the right metacarpal neck plate on the left hand.
The 1.3 mm Rotational Correction Plate is designed to be used with an osteotomy for correcting rotational malunions. A Rotational Osteotomy Cutting Guide is included in the Hand Fracture System that is designed to facilitate precise placement and orientation of cuts for rotational osteotomies of the metacarpals.
The 0.8 mm Offset Plate is designed to provide fixation for diaphyseal fractures. The 0.8 mm Curved Medial/Lateral Plate is designed for diaphyseal fractures when a medial or lateral approach is preferred. Offset Plates and Curved Medial/Lateral Plates, like all of the Hand Fracture System plates, are low profile, designed to reduce soft tissue irritation. All plates may be bent to fit and cut to length to better fit specific patient anatomy.
Standard plates include the Offset Plate, 6- and 10-Hole Straight Plates, and T-Plates. These plates come in 0.8 mm and 1.3 mm thicknesses, except the Offset Plate which is 0.8 mm only. Plates may be bent to fit and cut to length to better fit individual patient anatomy. Custom plate cutters included in the Hand Fracture System tray are designed to leave a rounded edge, designed to reduce soft tissue irritation. Plate cutters may be used with any Hand Fracture System plate except the Avulsion Plate.
ORIF of First Metacarpal Base Fracture: Marc J. Richard, MD: A 55-year-old, right-hand-dominant male fractured the base of his right first metacarpal during a fall at work. He was treated with a Rolando Fracture Hook Plate from the Acumed Hand Fracture System.
Phalangeal and Forearm Open Fractures Treatment With Internal and External Fixation: Marc J. Richard, MD: A 34-year-old gunshot wound victim with a highly comminuted forearm fracture and an index finger injury was treated with the Acumed Small Bone External Fixator and an anatomic forearm plate.
Metacarpal Lengthening Using Distraction Osteogenesis: Marc J. Richard, MD: Post-amputation of his thumb, a 38-year-old male opted for metacarpal lengthening with the Acumed Small Bone Distractor to create a thumb that could allow pinch and grasp.
Open Reduction and Internal Fixation of the Proximal Phalanx: Marc J. Richard, MD: A 62-year-old man sustained a proximal phalanx fracture in Iraq. After initial external fixation, he was treated with open reduction and internal fixation using a Curved Medial/Lateral Plate from the Acumed Hand Fracture System.
Open Reduction & Internal Fixation of a Fifth Metacarpal Neck Fracture: Marc J. Richard, MD: A 24-year-old woman sustained multiple fractures in a motor vehicle accident, including a metacarpal neck fracture. This fracture was reduced and fixed using a Metacarpal Neck Plate from the Hand Fracture System.
Hexalobe MultiScrew and Lag Screw Technology
1. Designed to be used with any plate in the Hand Fracture System, 1.5 mm and 2.3 mm Hexalobe MultiScrews act as nonlocking screws when inserted into unthreaded slots and locking variable angle screws when inserted into threaded holes. The Hexalobe MultiScrew design allows for angles of up to 15 degrees in any direction for a total of 30 degrees. The SaveLock Compression Sleeve is designed to aid with plate reduction.
2. Designed to be used as an adjunct to plate fixation or for fractures which can be treated with lag screws alone, the 1.5 mm and 2.3 mm Hexalobe Lag Screws do not require overdrilling of the near cortex. Hexalobe Lag Screws are intended to be used independently of plates or through slotted plate holes only. When using lag screws as nonlocking screws in plates, ensure the screw engages the far cortex since lag screws are partially threaded and unable only partially to engage the near cortex. It is recommended to not use more than two lag screws per plate if they are being used as nonlocking screws.
Numerous Possible Plate Configurations
The Acumed Hand Fracture System offers plates in 0.8 mm and 1.3 mm thicknesses. Plates can be cut to length and bent to fit to better treat a wide variety of fracture patterns.
Multiple Choices, Multiple Options
Custom plate cutters are included in the Acumed Hand Fracture System, and are designed to create a smooth rounded edge on all plates except the Avulsion Plate. These plates feature divots that aid in provisional fixation when used with the system's forceps and clamps.
