This article explains, in educational terms, intramedullary nail — how the technology works and where it fits. Locking plates have threaded holes that lock screws at a fixed angle to create angular stability, which the site FAQ notes is particularly relevant for osteoporotic bone, whereas non-locking plates rely on friction between the plate and bone. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Fracture Fixation and Joint Reconstruction
Implant material choice, commonly medical-grade titanium alloys or stainless steel, influences strength, imaging behavior, and biocompatibility, and is considered alongside the fracture pattern. Orthopedic trauma solutions address the fixation of fractures and the reconstruction of joints, using implants intended to stabilize bone so that healing can occur in a corrected position. Joint reconstruction encompasses hip and knee prostheses and arthroscopy systems, extending the portfolio beyond acute fracture care into reconstructive surgery.

Design and Technical Notes
INVAMED's CytroFIX system is organized by implant type and anatomical region, spanning intramedullary nails, plates, and screws manufactured from medical-grade titanium. Implants are intended for use by trained orthopedic surgeons and per the IFU. Fracture location and pattern strongly influence the choice among intramedullary nailing, plating, and screw fixation. Manufacturer statements about the CytroFIX range, including the 35+ implant variants figure, reflect the company's product information rather than guaranteed clinical outcomes.
Key Considerations
- Bone quality, including osteoporosis, is a key factor in favoring fixed-angle locking constructs where screw purchase may be reduced.
- Implant material such as Ti-6Al-4V titanium affects strength, imaging behavior, and biocompatibility, and is weighed alongside the fracture.
- Manufacturer statements about the CytroFIX range, including the 35+ implant variants figure, reflect the company's product information rather than guaranteed clinical outcomes.
Frequently Asked Questions
What is the difference between locking and non-locking plates?
Locking plates lock screws to the plate at a fixed angle for angular stability that is useful in osteoporotic bone, while non-locking plates rely on plate-to-bone friction; the choice is the surgeon's.
Who decides which implant is used?
A qualified orthopedic surgeon selects the implant based on the fracture, bone quality, and patient factors; this article is educational and not a treatment recommendation.
Clinical and Technical Context
Manufacturer statements about the CytroFIX range, including the 35+ implant variants figure, reflect the company's product information rather than guaranteed clinical outcomes. Whether external fixation or an arthroscopic approach is appropriate is a clinical decision made by the surgeon based on the injury and patient status. All INVAMED orthopedic implants are intended for use by trained surgeons and in accordance with the IFU and applicable regulatory approvals. Plate type, contouring, and screw configuration are determined by the surgeon based on the fracture pattern and bone quality.
