hip
Enable an AI agent to identify a hip, describe its anatomical and functional state, and determine which observations or actions are appropriate given available evidence and constraints.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to identify a hip, describe its anatomical and functional state, and determine which observations or actions are appropriate given available evidence and constraints.
The hip is the synovial ball-and-socket joint (articulatio coxae) in which the femoral head articulates with the acetabulum of the pelvis, transmitting body weight to the lower limb and permitting multi-axial motion of the thigh.
It can be Attach an examination, image or reported symptom to the correct hip and anatomical structure.; Compare hip movement or task performance over time under recorded assessment conditions.; Compare left and right hips while retaining separate findings and avoiding an assumption that either side is normal.; Check whether a proposed movement, loading task or assessment conflicts with documented hip-specific restrictions.; Identify missing or conflicting evidence that requires clarification before interpreting hip condition or planning an action.; Link local findings to relevant clinical assessments and intervention records without inferring a diagnosis from a single observation..
Distinguishing features
Locate the articulation of a femoral head with an acetabulum; a pelvic landmark or sacroiliac articulation alone does not identify the hip joint.
Distinguish the joint itself from the broader lateral or anterior hip region by recording the anatomical referent of each observation.
Identify the proximal femoral articulation with the pelvis rather than the distal femoral articulation at the knee.
Distinguish a living hip containing replacement components from an isolated prosthetic device.
Resolve anatomical usage explicitly when the word 'hip' could instead denote a garment measurement, external body contour or plant fruit.
Scope
+ Identity, laterality and anatomical location of a particular hip
+ The femoral head-acetabulum articulation and its local supporting structures
+ Hip movement, stability and contribution to weight bearing
+ Locally observed symptoms, structural changes and functional limitations
+ Hip-specific intervention history, implanted components and action constraints
- The pelvis or femur as complete skeletal structures
- Lumbar spine and sacroiliac joints as independent anatomical entities
- The knee and the remainder of the lower limb
- Whole-person gait, mobility and systemic disease models
- Clinical encounters, treatment protocols and implant product specifications
Characteristics
- Anatomical referent
- joint; surrounding hip region; external landmark; unresolved Prevents observations about different anatomical extents from being treated as observations of the same structure.
- Organism and species
- reference to the individual organism and its species Anatomical interpretation and movement expectations depend on the organism.
- Laterality
- left; right; unresolved Separates the two hips and prevents findings or actions from being assigned to the wrong side.
- Articular configuration
- native; partially replaced; totally replaced; other surgically altered configuration; unknown Changes which structures exist and how observations and constraints should be interpreted.
- Joint alignment
- reported alignment or congruence, assessment method, time and uncertainty Records the relationship between articulating structures without inferring it from symptoms alone.
- Range of motion
- degrees by movement direction, with active or passive method, position and assessment time Makes movement limitation interpretable and comparable across assessments.
- Pain or discomfort
- location, reported quality, named severity scale, timing and provoking activity; absent or unknown where applicable Separates the reported experience from assumptions about its anatomical cause.
- Load-bearing performance
- observed task, loading conditions, assistance, symptoms and completion Shows what the hip contributes during a specific activity without confusing performance with permission to load it.
- Local tissue condition
- structure-specific observation, method, date and uncertainty Keeps findings about cartilage, bone, capsule, labrum and nearby soft tissues anatomically distinct.
- Current movement and loading restrictions
- reference to an applicable instruction, its issuer, affected side, conditions and review date Supports action decisions using documented constraints rather than assumed restrictions.

Hip identity and boundaries Establishes which hip and which anatomical extent an observation concerns.
The word hip can refer to a joint, a surrounding region or a body contour, and paired hips require unambiguous identification.
Organism and side
Anchors a hip to its organism and laterality.
Identified hip
Records the organism, species and side supported by the available identification evidence.
- Which organism, species and side does this hip record describe? definition
- What evidence establishes the side, and do examination notes and image labels agree? provenance
Joint and regional extent
Separates the articulation from adjacent tissues and neighbouring anatomical regions.
Observation anatomical boundary
Assigns each observation to the joint, a named local structure or an unresolved regional location.
- Does this observation concern the femoral head-acetabulum articulation, a surrounding structure or only a reported hip-area location? boundary
- Where does the observation cross into a pelvis, femur, lumbar spine or other neighbouring model? boundary
Hip structure and integrity Describes the articulation and local tissues as observed, including altered anatomy.
Hip function and permissible assessment depend on the configuration and condition of the articulating and supporting structures.
Articular configuration
Captures native or altered joint anatomy and the relationship between articulating components.
Articulating structures and alignment
Records which native structures or replacement components form the hip and what evidence describes their alignment.
- Which native articulating structures and replacement components are present in this hip? definition
- What examination, imaging or operative evidence describes their alignment, and when was it obtained? provenance
Local tissue integrity
Keeps observations of articular and periarticular tissues distinct.
Structure-specific condition
Records supported observations about named hip tissues without treating an unexamined structure as normal.
- Which hip structure was assessed, and what condition or change was actually observed? measurement
- Which local structures remain unassessed or cannot be resolved by the method used? boundary
Hip movement and load Captures movement capacity and hip contribution to specified loaded activities.
A structural description alone does not establish how a hip moves or performs during standing, transfers or locomotion.
Directional movement
Records hip motion with the conditions needed to interpret it.
Measured hip motion
Describes motion by direction, active or passive assessment, position and limiting response.
- What range was measured for each assessed hip movement, using which position and active or passive method? measurement
- Was the observed endpoint associated with pain, resistance, weakness, compensation or a documented precaution? measurement
Loaded task performance
Relates the hip to specific tasks while preserving whole-body and environmental context.
Hip contribution under load
Records performance during a named activity and distinguishes local evidence from whole-person limitations.
- During which task and loading conditions was hip performance observed, with what assistance or support? measurement
- What supports attributing the observed limitation to this hip rather than another joint, balance or general capacity? boundary
Hip symptoms and action context Connects reported symptoms, intervention history and current constraints to decisions about this hip.
Hip-area symptoms do not establish their source, and action decisions require current, attributable instructions and evidence.
Symptom location and course
Records symptoms in their spatial, activity and time context.
Reported hip symptom pattern
Preserves the location and course of symptoms separately from any proposed anatomical explanation.
- Where is discomfort reported, when does it occur, and which activities provoke or relieve it? measurement
- Who reported or observed it, and what evidence, if any, connects it to a particular hip structure? provenance
Interventions and current constraints
Tracks changes to the hip and the instructions governing proposed activities or assessments.
Hip intervention history
Links relevant procedures or injuries to the affected side, anatomical changes and dated evidence.
- Which documented injuries or interventions changed this hip, and when? provenance
- Which anatomical or functional consequences are documented, and which remain unknown? boundary
Permitted next action
Checks a proposed hip-related action against applicable instructions and unresolved information.
- What current instruction governs the proposed hip movement, loading task or assessment, and who issued it? provenance
- Does the proposed action meet those conditions, or must a specific uncertainty be resolved first? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Kinds and varieties
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- native (unreplaced) hip joint
- hip region (coxal region of the lower limb)
- primary osteoarthritis of hip
- total hip arthroplasty / prosthetic hip
- hip dysplasia (developmental dysplasia of the hip)
- femoroacetabular impingement morphology
- pediatric / immature hip
- hip fracture (proximal femoral fracture involving the hip)
- Which of these kinds and varieties hold for the sense of hip this model covers, and on what evidence? provenance
Sources
- pending research - will be replaced
What the second pass must settle
- Does the registry intend hip to mean the joint specifically or the broader anatomical region?
- Should this entry cover hips across species, or should its initial operational scope be human anatomy?
- Which adjacent registry entries own the labrum, capsule, periarticular muscles and bursae, and how should shared observations be linked?
- Which assessment methods and contextual reference values should support comparisons across age, species and surgically altered hips?
- Does an existing Vercy world model already cover this anatomical concept and therefore provide the authoritative publication?
