TissueDB/Simulators/Long Bone Drilling Simulator

Long bone drilling is the psychomotor skill this trainer rehearses for learners new to using a drill. The Long Bone Drilling Simulator adapts ETALO's Basic Bone Drilling Simulator (Education To Advance Limb-Saving Options for Open Fractures and Osteomyelitis) into a low-cost build. A bone analog sits in a stabiliser on a flat surface; the learner drills into it. Two variants exist: bamboo with clay, and PPR pipe with play-dough. The original instructions are at the ETALO Basic Bone Drilling Simulator page on Appropedia.
| Field | Details |
|---|---|
| Features and Basic Operation | The learner drills into a bone analog — bamboo or PPR pipe — held in a clay or play-dough stabiliser on a flat surface. This rehearses basic bone drilling for learners new to using a drill. An optional plunge-detector layer is documented separately. |
| Current Development Status | Pilot-tested |
| Estimated Build Time and Cost | Not stated in source., ~US$10 |
| Specialized Tools and Equipment | Hand or electric drill with drill bit |
| Version | Version 1 |
| Development Team Contact Information | ETALO — orthopaedic surgeons, engineers, and education/assessment specialists from Uganda, USA, and Canada. Developed for the Global Surgical Training Challenge, 2020. |
Tissues
| Tissue | Qty | Material | Cost | Notes |
|---|---|---|---|---|
| Bone | 1 piece | Bamboo | $1–3 | Variant A: Small-diameter bamboo stick or pole. Acts as bone for drilling practice. |
| Bone | 1 piece | PPR Pipe | $2–5 | Variant B: PPR (Polypropylene Random Copolymer) pipe. Small-diameter plumbing pipe. Acts as bone for drilling practice. |
Structural Parts
| Part Name | Qty | Material | Cost | Notes |
|---|---|---|---|---|
| Stabiliser | Sufficient to stabilise bone | Clay (moldable) or Play-dough | $3–10 | Non-hardening modelling clay (Variant A) or play-dough (Variant B). Holds bone analog in place during drilling. |
Build Instructions
Phase 1: Variant A — Bamboo + Clay
Step 1: Apply moldable clay to a hard flat surface as a stabiliser.
Step 2: Insert the bamboo (acting as bone) into the clay so it is held securely in place for drilling.
Phase 2: Variant B — PPR Pipe + Play-Dough
Step 1: Apply play-dough to a hard flat surface as a stabiliser.
Step 2: Insert the PPR pipe (acting as bone) into the play-dough so it is held securely in place for drilling.
Additional Bone Layer Options

The following bone analog materials are listed in the ETALO Basic Simulator Matrix but are not demonstrated in the instructional videos:
- Animal bone
- Play-dough pipe (hardened)
