Femoral head compression plate FNS

laterallockingtitanium

Product introduction
The Femoral Neck System (FNS) is a fixation system intended for the treatment of femoral neck fractures in adults. Model: FNS. Indicated for basal, transcervical and subcapital femoral neck fractures. Not indicated for pertrochanteric, intertrochanteric or subtrochanteric femoral fractures.

Features

• Enhanced anti-rotation & angular stability: The anti-rotation screw and main implant interlock with a 7.5° divergence to provide control of femoral head rotation. The plate and main implant form an angular-stable construct at a 130° neck–shaft angle to resist varus collapse and femoral neck shortening.
• Intraoperative active compression & postoperative dynamic sliding: Main implant and anti-rotation screw lock together to allow controlled dynamic sliding up to 20 mm under postoperative loading, enabling controlled impaction and load sharing during healing.
• Reduced implant footprint: Compact profile compared with a conventional Dynamic Hip Screw (DHS); lateral footprint comparable to three cannulated screws to facilitate minimally invasive insertion and reduce lateral prominence.
• Soft-tissue and bone preservation: Design aims to preserve lateral bone/soft-tissue space while providing rotational control and angular stability.

Application

• Indications: Basal, transcervical and subcapital femoral neck fractures in adults.
• Contraindications: Pertrochanteric, intertrochanteric and subtrochanteric femoral fractures.

Notes
Implant geometry and component locking are designed to combine rotational control with angular stability while permitting controlled sliding for fracture compression and physiologic load sharing during healing.
