China MASFIN Femur Intramedullary Nail Implant Manufacturer, Manufacturers
Product Description
The introduction of femoral intramedullary nail has completely changed the way orthopedic surgery is performed, providing a minimally invasive solution for stabilizing femoral fractures. This device is a slender rod inserted into the medullary cavity of the femur for internal fixation of fractures. The design of intramedullary nails enables them to distribute weight and stress along the length of the bone, promoting optimal healing while reducing the risk of complications.

Indications & Clinical Application
Standard Locking
- The MASFIN Femoral Nail with standard locking is indicated for fractures in the femoral shaft: 32-A/B/C (except subtrochanteric fractures 32-A [1–3].1 and 32-B [1–3].1).
- Femoral shaft fractures (except subtrochanteric fractures).
Recon Locking
- The MASFIN Femur Nail with recon locking is indicated for fractures in the femoral shaft in case of combination with femoral neck fractures: 32-A/B/C combined with 31-B (double ipsilateral fractures).
- Subtrochanteric fractures.
- Combined femoral shaft and neck fractures.
- Additionally the Expert Lateral Femoral Nail is indicated for fractures in the subtrochanteric section: 32-A [1–3].1 and 32-B [1–3].1.

Key Design & Anatomical Benefits
Anatomical Fit & Entry
- The lateral flattened cross-section ease insertion.
- The curvature of shaft part fits the femoral anatomical characters.
- Optimal Lateral Entry Point: Easier access to entry site, time-saving surgical technique.
- Less soft tissue damage with lower risk of avascular necrosis.
Spiral Flute Engineering
- The design of spiral flutes on the shaft part reduce the inserting resistance and improve the stress distribution, avoiding the stress concentration of the contact position after placement.
- The spiral flutes on the right side are clockwise, on the left side are anticlockwise.

Frequently Asked Questions (FAQ)
What material is used for the MASFIN Femoral Nail system?
The system is manufactured from high-grade Titanium Alloy treated with Micro-arc Oxidation surface treatment to enhance durability and biocompatibility.
What are the primary clinical indications for standard vs recon locking?
Standard locking is mainly indicated for femoral shaft fractures (32-A/B/C). Recon locking is specifically designed for subtrochanteric fractures and complex combinations of femoral shaft and femoral neck fractures (32-A/B/C combined with 31-B).
How does the spiral flute design benefit surgical placement?
The specialized spiral flutes reduce insertion resistance, distribute mechanical stress evenly along the nail, and minimize stress concentration at the contact zones after placement. The flutes are engineered clockwise for right nails and anticlockwise for left nails.
What advantages does the lateral entry point offer?
An optimal lateral entry point facilitates easier surgical access, saves operation time, reduces damage to surrounding soft tissues, and substantially lowers the risk of avascular necrosis.
What regulatory certifications and packaging options are available?
The implant is certified under ISO13485 and NMPA standards. Each component is provided in individual sterile packaging (1 pc/package) with a minimum order quantity (MOQ) of 1 piece.
