This guide offers an educational, technical overview of orthopedic & trauma solutions and the device technologies used in this field. Joint reconstruction encompasses hip and knee prostheses and arthroscopy systems, extending the portfolio beyond acute fracture care into reconstructive surgery. 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
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. 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.
Core Technologies and Options
Intramedullary Nails. An intramedullary nail is a rod inserted into the medullary canal of a long bone to act as an internal splint that shares load and stabilizes a fracture from within. Interlocking screws at the proximal and distal ends control length and rotation and can provide static or dynamic fixation depending on how they are placed. Tibia Nails. Tibial nailing stabilizes tibial shaft and selected metaphyseal fractures with an intramedullary rod, allowing the bone to heal along a restored axis. High-purity titanium construction is intended to combine strength with biocompatibility, and versatile locking options let the surgeon tailor stability. Femoral Nailing and PFN. Femoral nailing addresses fractures of the femoral shaft and, in the case of the proximal femoral nail (PFN), fractures of the proximal femur and trochanteric region. Anatomical curvature that matches femoral anatomy and a low-profile proximal geometry are intended to support accurate placement and fit. Locking and Compression Plates. Locking plates use threaded screw holes that lock the screw head to the plate at a fixed angle, creating a fixed-angle construct that provides angular stability without relying on plate-to-bone compression. As the site FAQ notes, this angular stability is especially useful in osteoporotic bone, whereas non-locking plates depend on friction between the plate and bone surface. Cannulated and Cortical Screws. Cannulated screws are hollow so they can be placed over a guidewire, which supports accurate positioning for fractures amenable to screw fixation. Cortical screws are designed for purchase in the dense cortical bone and are available in variants that suit different fixation needs. Magnetic Lengthening Nails. A magnetic intramedullary lengthening nail contains an internal, magnetically driven mechanism that allows gradual, controlled limb lengthening after implantation. By adjusting the nail externally, the surgical team can progress lengthening incrementally as part of a limb-reconstruction plan.
Comparing the Approaches
Intramedullary nail vs Locking plate. An intramedullary nail stabilizes a long-bone fracture from within the medullary canal as a load-sharing splint, while a locking plate is applied to the bone surface and provides a fixed-angle construct. INVAMED offers both approaches within CytroFIX, including intramedullary nails and titanium locking plates such as the Distal Tibia Medial Plate. Plate vs Nail for distal tibia fracture. For distal tibia fractures, both plating and nailing are described in the literature, and the decision is influenced by how close the fracture is to the joint and the soft-tissue condition. INVAMED provides both the CytroFIX Distal Tibia Medial Plate and the CytroFIX Intramedullary Tibia Nail for these scenarios. Titanium implants vs Stainless steel implants. Titanium alloys such as Ti-6Al-4V are valued for a favorable strength-to-weight ratio, corrosion resistance, and biocompatibility, and generally produce fewer imaging artifacts than stainless steel. INVAMED's CytroFIX implants are described as medical-grade titanium (Ti-6Al-4V ELI), reflecting the titanium option within this comparison.

Key Considerations
- 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.
- Implant material such as Ti-6Al-4V titanium affects strength, imaging behavior, and biocompatibility, and is weighed alongside the fracture.
Frequently Asked Questions
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.
What diameters do the femoral nails come in?
According to invamed.com content surfaced via the search index, CytroFIX intramedullary nails cover femoral fractures in the 9 to 13 mm diameter range, along with tibial and humeral options.
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.
