This article explains, in educational terms, external fixation — how the technology works and where it fits. 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. 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
Joint reconstruction encompasses hip and knee prostheses and arthroscopy systems, extending the portfolio beyond acute fracture care into reconstructive surgery. Implant material choice, commonly medical-grade titanium alloys or stainless steel, influences strength, imaging behavior, and biocompatibility, and is considered alongside the fracture pattern. 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.
External Fixation and Arthroscopy
External fixators stabilize a fracture using pins or wires connected to an external frame, which can be useful in complex or contaminated injuries where internal fixation is not immediately appropriate. Arthroscopy systems allow minimally invasive visualization and treatment within a joint, supporting reconstructive procedures alongside the trauma portfolio. INVAMED's orthopedic and trauma range includes external fixators, hip and knee prostheses, and arthroscopy systems in addition to nails, plates, and screws. Whether external fixation or an arthroscopic approach is appropriate is a clinical decision made by the surgeon based on the injury and patient status.
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. Bone quality, including osteoporosis, is a key factor in favoring fixed-angle locking constructs where screw purchase may be reduced. 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
- Implant material such as Ti-6Al-4V titanium affects strength, imaging behavior, and biocompatibility, and is weighed alongside the fracture.
- All INVAMED orthopedic implants are intended for use by trained surgeons and in accordance with the IFU and applicable regulatory approvals.
- Bone quality, including osteoporosis, is a key factor in favoring fixed-angle locking constructs where screw purchase may be reduced.
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.
What material are CytroFIX implants made from?
INVAMED describes CytroFIX implants as medical-grade titanium (Ti-6Al-4V ELI), selected for high strength, corrosion resistance, and biocompatibility, with an anatomical design and interlocking options.
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
INVAMED offers CytroFIX Cannulated Screws and CytroFIX 2.0 Cortical Screws, including 2.0 mm cortical and locking cortical variants available in variable-angle, fixed-angle, spherical, and dynamic versions. Which implant and technique are appropriate depends on the fracture type, bone quality, and patient factors, and is determined by the treating orthopedic surgeon. 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. INVAMED's CytroFIX Intramedullary Tibia Nail features high-purity titanium construction with versatile proximal and distal locking options.
