Cannulated Screws
Cannulated screws are orthopedic fixation screws with a hollow shaft that accommodates a compatible guide wire for guided insertion. Stahlmann Pro offers titanium and stainless steel cannulated screws in diameters from 3.0mm to 7.3mm, with cortical, cancellous and multiple thread configurations.
Cannulated Screws for Orthopedic Fixation
Selecting a cannulated screw involves more than choosing its diameter. Overall length, threaded length, guide wire compatibility and drive size help distinguish the available options.
The Stahlmann Pro range includes screws with listed applications in forearm, hand, foot, ankle, femoral and pelvic fixation. Indications vary by screw model. Each product page provides its specifications, listed applications and catalogue codes so buyers can identify the required configuration.
Cannulated Cortical and Cancellous Screws
The range includes both cortical and cancellous screw designs.
The 3.5mm and 4.5mm cannulated cortical screws have thread profiles designed to provide pullout resistance and insertion efficiency similar to standard cortex screws of the corresponding diameter.
The supplied specifications for 3.0mm, 4.0mm, 7.0mm and 7.3mm cannulated cancellous screws describe deep cutting threads with a large pitch. This thread profile is designed to increase resistance to pullout and support efficient insertion and removal.
The 6.5mm Cannulated Screw is listed separately with 16mm thread, 32mm thread and fully threaded self-drilling configurations.
Available Screw Diameters and Configurations
| Product | Thread configurations listed in the catalogue |
|---|---|
| 3.0mm Cannulated Cancellous Screw | Short thread and long thread |
| 3.5mm Cannulated Cortical Screw | Short thread and full thread, including self-tapping versions |
| 4.0mm Cannulated Cancellous Screw | Short thread and full thread, both self-tapping |
| 4.5mm Cannulated Cortical Screw | Short thread and full thread, including self-tapping versions |
| 6.5mm Cannulated Screw | 16mm thread, 32mm thread and full thread, all self-drilling |
| 7.0mm Cannulated Cancellous Screw | 16mm thread, 32mm thread and full thread, all self-drilling |
| 7.3mm Cannulated Cancellous Screw | 16mm thread, 32mm thread and full thread, all self-drilling |
Thread Length and Fixation Requirements
For partially threaded screws intended to create interfragmentary compression, the threaded portion must engage the far bone fragment. Different thread lengths help match that engagement to the fragment dimensions.
Overall screw length and thread length are separate measurements. For example, the catalogue lists a 70mm screw with either a 16mm or 32mm threaded portion in the 6.5mm, 7.0mm and 7.3mm ranges.
The supplied specifications for the 3.5mm and 4.5mm cortical screws and the 4.0mm cancellous screw identify fully threaded versions for stabilization where little or no compression across the fracture site is required.
Titanium and Stainless Steel Options
All seven screw ranges are available in titanium and stainless steel. Separate catalogue codes identify each material option.
When requesting a quotation, specify the screw diameter, overall length, thread configuration and material. Including the exact product code helps distinguish versions that share the same dimensions.
Guide Wire and Instrument Compatibility
Guide wire requirements vary by screw diameter. Confirm compatibility for the individual product rather than using one guide wire size across the range.
| Screw diameter | Specified guide wire diameter |
|---|---|
| 3.0mm | 1.1mm, with a threaded trocar tip |
| 3.5mm | 1.2mm |
| 4.0mm | 1.2mm |
| 4.5mm | 1.6mm, with a threaded trocar tip |
| 7.0mm | 2.0mm |
| 7.3mm | 2.2mm |
Drive dimensions also differ. The supplied specifications list a 2.5mm hexagonal drive for the 4.0mm screw, a 3.5mm hexagonal drive for the 7.0mm screw, and a 4.0mm hexagonal socket for the 7.3mm screw.
