Phalangeal and metacarpal fractures are the second and third most common fractures of the upper limb, respectively, after distal radius fractures. Together, they account for approximately 40% of all upper extremity fractures.
Neutralization screw fixation represents an advancement in the management of phalangeal and metacarpal fractures. By combining stability, soft tissue preservation, and minimally invasive approach, this technique meets the key objectives of hand surgery: enabling early mobilization, promoting functional recovery, and reducing the risk of potential complications.
The implants in the Stand-Alone Screws range are intended for the fixation of fractures, osteotomies, and bone arthrodeses in adults, and are appropriately sized for the device.
A minimally invasive alternative for shaft fracture fixation.
- Three screw diameters: Ø2.0 mm, Ø3.0 mm, and Ø4.0 mm.
- Cannulated screws for guided insertion over the K-wire (Ø0.9 mm for Ø2.0 mm screws; Ø1.3 mm for Ø3.0 mm and Ø4.0 mm screws).
- Non-compressive design to provide neutralization and avoid bone shortening.
- Evolutive diameter to maximize cortical anchorage and optimize isthmus filling.
- Self-drilling and self-tapping properties: both the screw tip and head have been specifically designed to facilitate insertion.
- Mutualized instrumentation for Ø3.0 mm and Ø4.0 mm screws for simplified use.
A 2-in-1 instrument for selecting the appropriate screw size: measurement of the isthmus diameter using the tip and measurement of screw length using the differential gauge.
- Designed to support bone fragment alignment and fracture reduction.
- Cannulated instrument allowing guided positioning over the K-wire (Ø0.9 mm for Ø2.0 mm screws; Ø1.3 mm for Ø3.0 mm and Ø4.0 mm screws).
- Pointed tip allowing insertion into the first cortex without pre-drilling.
- Color-coded ring system enabling efficient selection of instruments corresponding to the screws used during surgery.
- Double function:
- Facilitates screw insertion in cases of rotational instability.
- Supports screw removal by providing anchorage when the screw spins freely due to loss of cortical engagement.
- Radiolucent instrument.
- Compatible with all screw diameters in the range.
