External Fixation Hardware

Modular External Fixation Hardware

Any locally available 4.0 or 5.0 mm diameter self-drilling Schanz Screws and compatible modular external fixator hardware, instruments, and surgical drill can be used for this skills training module.

Humeral Fracture Modular External Fixation Hardware List

#	Item	Quantity	Reference Photo	Function	Reusable for Simulation Training
1	Any powered orthopedic surgical drill that is compatible with 4.0 or 5.0 mm diameter self-drilling Schanz screws	1		Drives Schanz Screw into fracture fragment, also referred to as "power drive"	Yes
2	Chuck Key for Surgical Drill	1		Used to tighten or loosen the drill chuck jaws over the Schanz screw	Yes
3	Triple Drill Sleeve Assembly, 5.0 mm (consisting of an inner trochar, middle drill sleeve and outer cannula components)	1		Protects the soft tissue when drilling Schanz Screws; the triple drill sleeve assembly must be inserted before drilling to protect the soft tissue overlying the humerus in the real clinical scenario; the inner trochar is removed before drilling	Yes
4	Self-Drilling Schanz Screws, 5.0 mm x 200 mm x 30 mm	4		Inserted into fracture fragments, also referred to as "pins" and "half-pins"	No; re-using Schanz Screws may cause mechanical failure of the 3D Printed Adult Humeral Bone Models
5	Jacobs Chuck T-Handle	1		Allows for manual advancement of the Schanz Screw to the desired depth	Yes
6	Chuck Key for Jacobs Chuck T-Handle	1		Used to tighten or loosen the Jacobs Chuck T-Handle chuck jaws over the Schanz screw	Yes
7	Universal Clamp (Single Pin)	4		Combines pin-to-rod	Yes
8	Connecting Rod, 11 mm x 150 mm	2		Links pins with clamps, available in several sizes	Yes
9	Rod-to-Rod Connector	2		Combines rod-to-rod	Yes
10	Connecting Rod, 11 mm x 100 mm	1		Links pins with clamps, available in several sizes	Yes
11	11 mm Spanner with T Handle	1		Assists in final tightening of clamps	Yes

4.0 mm diameter Schanz Screws may also be used for open humeral shaft fractures.
