Medartis | Hand 1.2-2.3 System

Designed to perform.

The hand is one of the most complex and most frequently utilized parts of the human musculoskeletal system. It is composed of a multitude of closely balanced structures, e.g. bones, muscles, ligaments, tendons, joints and nerves. The goal of hand surgery is to minimize the impact of hand diseases and injuries on daily activities and to restore and obtain as much functionality as possible.

The APTUS Hand System offers a comprehensive selection of both basic and specialized plates for treatment of fractures, osteotomies and arthrodesis of the hand. With 65 unique titanium plates the system stands out with a 1.2 multidirectional and angular stable locking system along with 1.5 self-drilling screws for hand osteosynthesis. It also includes indication specific plates, a broad selection of hook plates for bony avulsions, and plates combining locking and compression in one step. Color-coded instrumentation, a secure connection between screw and screwdriver, new forceps and clamps to support the surgical procedure and a modular storage solution complete the performance you expect.

The science behind.

Outcomes of Unstable Scaphoid Nonunion With Segmental Defect Treated With Plate Fixation and Autogenous Cancellous Graft Putnam JG, Mitchell SM, DiGiovanni RM, Stockwell EL, Edwards SG 2019 J Hand Surg Am.

The authors describe the clinical performance of the Scaphoid plate for treating scaphoid non-unions with a segmental defect. They conclude that: "The combination of scaphoid plate fixation and pure cancellous bone grafting for scaphoid nonunion with segmental defects yields reliable union rates and good patient outcomes.”

Plate Fixation With Cancellous Graft for Scaphoid Nonunion With Avascular Necrosis Putnam JG, DiGiovanni RM, Mitchell SM, Castañeda P, Edwards SG. 2019 J Hand Surg Am.

This study reviewed the clinical performance of the Scaphoid Plate for scaphoid nonunions with avascular necrosis, showing excellent union rates and good patient-reported and functional outcomes.

Holding and Positioning Instrument

Firmly hold and position the plate using the plate holding forceps (A-2052).

Lag Screw Clamp

The lag screw clamp is available in a left (A-2066.01) and right (A-2066.02) design option to accommodate different fracture locations and surgeon’s preference. Different screw types like cortical, Trilock but also CCS can be used with the Clamp.

Plate Cutting

Ensure that there are no remaining plate segments in the cutting pliers (visual check). Insert the plate from the front into the open cutting pliers. Always ensure that the labeled side of the plate is facing upwards. Hold the implantable plate segment with your hand during and after cutting.

Temporary fixation using olive K-wires

The olive K-wires can be inserted through the screw holes or through the K-wire holes in the plate.The K-wires with olive are available in a threaded and a non-threaded option, and with different tip lengths (10 or 15 mm).
