The PFN Lag Screw has a diameter of 11mm and is channeled throughout its entire length. It also features a cannulated structure and works integrally with the compression screw.
The PFN Cannulated Set Screw is used to secure the PFN Compression Screw and the PFN Lag Screw.
The PFN Compression Screw works in integration with the PFN Lag Screw. If compression up to 5mm is desired on the fracture line, the compression screw should be selected to be 5mm shorter than the lag screw. If 10mm compression is desired, the compression screw should be selected to be 10mm shorter than the lag screw.
Linear Guide Mechanism Horizontal Machining Center HMC-500SH Machine frame adopts fully box-structured base to ensure long-term operation accuracy and stability of machine. Feed rate is greatly uprate, while cutting capacity and machining speed are both raised. To be shorten the cycle time. 3 axes configuration of pre-tension ball screw to eliminate thermal expansion. Direct-drive spindle assures the transmission accuracy and avoid lag error. Horizontal machining center without APC. Space-saving and suitable for tailor-made production line. Characteristics: stable, four slides with eight blocks supported the broad base to acquire the optimal dynamic balance during processing.
PFN Intramedullary Nails: These are used in proximal femoral neck fractures, subtrochanteric fractures, and intertrochanteric fractures. The proximal part of the nail has a triangular cross-section with a radiused, angled design that prevents rotation. The distal part has a circular cross-section with a slot that allows for both dynamic and static locking. Additionally, the distal part is channeled, designed to reduce thigh pain. The proximal section includes a channel at a 125° angle through which the integral compression and compression screw pair passes. This screw pair can provide up to 10mm of compression at the fracture line using the appropriate sizes. An inner compression screw is used to restrict the movement of this screw pair. Additionally, a peak screw is located at the proximal end. The nail has a cannulated, closed structure and features a 5° lateral offset angle.
