Precision Cannulated Screw Systems Manufacturing

A cannulated screw is an orthopedic fixation screw manufactured with a hollow channel through its central axis. The channel can support guidewire-assisted placement during a surgical procedure. For device OEMs, producing these components requires controlled machining and inspection across the screw’s geometry, threads, drive features, and internal passage. MoManTech supports precision orthopedic component manufacturing for trauma, spine, joint, and extremity applications.

A cannulated screw contains a central hollow passage, while a non-cannulated screw is generally solid through its shaft. The cannulated design can be guided over a wire during placement, whereas a non-cannulated design does not use that internal channel. Manufacturing requirements differ accordingly, particularly around concentricity, internal geometry, thread quality, inspection, and process control.

MoManTech provides contract manufacturing for highly engineered orthopedic medical device components, including surgical implants and instrumentation. The appropriate manufacturing scope for a cannulated screw system depends on the supplied design, specifications, production requirements, and documentation needs. Capabilities include design-for-manufacturability consultation, CNC machining, Swiss turning, wire EDM, additive prototyping, finishing, part marking, inspection, and quality documentation.

Yes. MoManTech supports prototype development and low-volume production for precision-machined and 3D-printed orthopedic components. Its capabilities are suited to OEMs developing new spinal, trauma, large joint, and foot-and-ankle devices. The team can participate during planning through design-for-manufacturability consultation, then apply appropriate machining, additive, inspection, and quality-control processes to support the device program.

Available processes include precision CNC milling and turning, multi-axis Swiss lathe work, wire EDM, and additive manufacturing for prototyping or custom fixturing. MoManTech also provides finishing, laser marking, comprehensive inspection, and documented quality support. The process selection is based on the component design, required features, material requirements, production stage, and applicable customer specifications.

Material selection is determined by the device design, customer specifications, and applicable regulatory requirements. MoManTech’s catalog identifies metal additive options including 17-4 stainless steel, 316L stainless steel, and titanium beta, along with plastic and composite options such as Onyx, carbon fiber, Kevlar, fiberglass, and HSHT fiberglass reinforcement. Machined material requirements should be reviewed during project planning.

MoManTech describes comprehensive quality control, inspection, and documented quality support as part of its medical device manufacturing services. Its work is performed under ISO 13485:2016 compliance and FDA-regulated processes, according to the supplied company and service information. Documentation requirements can be aligned with the OEM’s specifications and the needs of the applicable device program.

An OEM can begin by sharing the component design, drawings, specifications, intended application, material requirements, production expectations, and documentation needs. MoManTech can then review manufacturability and identify suitable machining, wire EDM, additive, finishing, inspection, and marking capabilities. This planning stage helps establish an appropriate path for prototype development, low-volume production, or production manufacturing.
