Tibial Shaft Transverse Fracture Simulator

The 3D printed bone models of the Tibial Shaft Transverse Fracture Simulator feature a semi-engraved model number, gender symbol, and two drilling direction arrows on the base of each model to assist with model identification and proper orientation of the simulator.

This data-driven, gender-specific, easy to print, environmentally friendly, hygienic, and cruelty-free simulator can be locally made to provide the highest fidelity orthopedic surgical simulation training at the lowest cost in resource-constrained settings. Clear cellophane is wrapped around the slightly distracted 3D printed proximal and distal fracture fragments to simulate the soft tissue envelope and permit visual inspection for targeted self-assessment by the learner. The vise clamps are positioned so the fracture ends are distracted by 2.0 - 3.0 mm but are otherwise properly aligned to simulate a fracture with restored angulation, and rotation.

Materials and Equipment

1
For the Tibial Shaft Transverse Fracture Simulator, the 3D Printed Adult Tibial Bone Model 1 (left) is the proximal fragment, and the 3D Printed Adult Tibial Bone Model 2 (right) is the distal fragment.

2
Roll of clear cellophane wrap to simulate the soft tissue envelope overlying the proximal and distal fragments (left), 2 blue vise clamps to secure the Tibial Shaft Transverse Fracture Simulator (middle), and 4 black G-clamps to secure the blue vise clamps to a table (right).
Miscellaneous Supplies
  • Clear cellophane
  • Vise clamps (minimum 2)
Based on user feedback, we are now recommending learners obtain two 2-in-1 vise clamps instead of two table clamps and four G-clamps to secure the bone models. These 2-in-1 vise clamps are easier to use, cheaper overall ($17 USD/clamp) and can be obtained locally but the delivery times are longer (2 weeks) because they are imported. We will be updating our simulator build video to showcase these 2-in-1 vise clamps soon.
3
Any powered orthopedic surgical drill that is compatible with 5.0 mm diameter self-drilling Schanz screws can be used.
Powered Surgical Drill and Accessories
  • 5.0 mm diameter self-drilling Schanz screw
  • Chuck key
  • Powered surgical drill
The Arbutus Medical HEX Drill Kit uses autoclavable drill covers to permit faster turnaround on reprocessing orthopedic surgical drills in resource-constrained settings.[1]

Collect Supplies

Obtain the following supplies:

2
Arbutus Medical HEX Drill with 5.0 mm diameter Schanz Screw and Chuck Key
Assemble Drill and Insert Schanz Screw
  • Follow the surgical drill manufacturer's instructions on how to assemble the surgical drill and insert a 5.0 mm diameter self-drilling Schanz screw using the chuck key.
  • If using the Arbutus Medical HEX Drill Kit, follow the video instructions to assemble the Arbutus Medical HEX Drill and insert a 5.0 mm diameter self-drilling Schanz screw.
A sterile person is NOT required to assemble the Arbutus Medical HEX Drill for simulation training.
3
Test Drill to Confirm Drilling Direction
  • If using the Arbutus Medical HEX Drill Kit, push on the forward drilling direction switch on the right side of the drill for clockwise rotation. NOTE: Different drills have different locations for the switch that controls forward drilling direction.
  • Test the surgical drill by squeezing the on/off trigger to confirm that the drill is ready for use. The Schanz screw tip should be rotating in a clockwise direction when the Schanz screw tip is pointing away from you.
