What it is Filled
The elbow is the free-upper-limb region between arm and forearm that houses the compound synovial joint of distal humerus, proximal radius and proximal ulna, whose shared capsule encloses a humeroulnar hinge, a humeroradial articulation, and a proximal radioulnar pivot.
In scope
- Elbow identity, organism, side and anatomical boundaries
- Local articulations, stabilising tissues and their documented condition
- Elbow bending, straightening and contribution to forearm rotation
- Local symptoms, visible changes and task-dependent functional limitations
- Elbow-specific restrictions, supports, interventions and reassessment
Out of scope
- Whole-person health, diagnoses and treatment plans
- Complete upper-limb anatomy and coordinated limb performance
- Shoulder, wrist and hand structure and function
- Systemic diseases that may affect the elbow
- Standalone models of implants, braces and prosthetic devices
- Pipe elbows and other non-biological angled connectors
Why it exists Filled
Enable an AI agent to recognise a biological elbow, record its structure and functional state, and identify which movements, observations or interventions require further evidence or authority.
Distinguishing features Filled
- The referent is an anatomical region or joint complex at the upper-arm-forearm junction, rather than a manufactured bend.
- In the human reference case, its anatomical identification involves the distal humerus and proximal radius and ulna; a shoulder or wrist has different participating bones.
- The referent encompasses the elbow articulation or region rather than only the olecranon, the palpable bony prominence commonly called the point of the elbow.
- An elbow assessment distinguishes bending and straightening from forearm rotation; observed rotation alone does not identify elbow motion.
- A suspected non-human elbow requires organism-specific anatomical correspondence rather than identification from a visible limb bend alone.
What robots and AI may and may not do Filled

May

Open questions
- Does registry entry vr.tr.elbow cover human elbows only, or homologous structures across other organisms?
- Does an existing Vercy world model already own the elbow concept, requiring a registry link rather than a separate publication?
- Which anatomical boundary should be canonical for the elbow region, particularly for adjacent tendons, bursae, nerves and vessels?
- Which measurement conventions and reference populations should support interpretation of elbow motion and task capacity?
- Which authoritative assessment and care sources should define action constraints and reassessment criteria for different elbow states?
