Here is a complete overview of Dupuytren's disease classification.
Dupuytren's Disease - Classification
Background
Dupuytren disease is a benign fibroproliferative disorder of the palmar fascia. The predominant cell type is the myofibroblast, which produces an increase in the ratio of type III to type I collagen. The ring finger is most commonly affected, followed by the small and long fingers. - Miller's Review of Orthopaedics 9e
1. Tubiana Classification (Most Widely Used)
The Tubiana system (1968) classifies each digit individually by calculating the total extension deficit (TED) = sum of flexion contractures at the MCP + PIP + DIP joints.
| Stage | Total Extension Deficit (MCP + PIP + DIP) | Points |
|---|---|---|
| 0 | No lesion | 0 |
| N | Palmar/digital nodule without flexion deformity | 0.5 |
| I | 0° - 45° | 1 |
| II | 45° - 90° | 2 |
| III | 90° - 135° | 3 |
| IV | > 135° | 4 |
- Each finger is scored separately (0 to 4 points)
- A total score of 8 or more across all fingers is considered severe disease
- The full possible range is 0.5 to 23 (all 5 digits affected)
- For the thumb web space, a separate subclassification applies based on restriction of first metacarpal anteposition
Tubiana also classifies the first web contracture separately:
| Stage | First Web - Anteposition of 1st Metacarpal |
|---|---|
| 0 | > 45° (normal) |
| I | 45° - 30° |
| II | 30° - 15° |
| III | < 15° |
2. Luck's Histological Classification (1959)
This classifies the disease by the histological phase of the Dupuytren tissue:
| Phase | Description |
|---|---|
| Proliferative | Active fibroblast proliferation; highly cellular nodules |
| Involutional | Myofibroblasts align with lines of stress; beginning contraction |
| Residual | Fibrocytes only remain; relatively acellular fibrous cord; late contracture |
This classification is useful for understanding disease biology and predicting recurrence risk after surgery.
3. Mikkelson Classification (1976)
A simplified epidemiological staging system based on Tubiana's framework (scoring abandoned):
| Stage | Description |
|---|---|
| I | Nodules or band without finger contracture |
| II | Overall contracture 1° - 45° |
| III | Overall contracture 46° - 90° |
| IV | Overall contracture 91° - 135° |
| V | Overall contracture > 135° |
4. Woodruff Clinical Grading System (1998)
A 5-grade practical system designed to correlate with operative time and surgical planning:
| Grade | Approximate Surgical Time |
|---|---|
| Grade 1 | ~30 min |
| Grade 2 | ~30 min |
| Grade 3 | ~60 min |
| Grade 4 | ~90 min |
| Grade 5 | Severe (bent fingertip touching palm) |
Letters are added to describe additional/predisposing features (e.g., bilateral disease, diathesis features).
5. Dupuytren Diathesis (Severity Marker)
Not a staging system per se, but a recognized clinical entity marking aggressive disease. Features include:
-
Bilateral hand involvement
-
Early age of onset (< 40 years)
-
Ectopic fibromatosis: plantar (Ledderhose disease), penile (Peyronie disease), dorsal PIP knuckle pads (Garrod nodes)
-
Strong family history
-
Higher recurrence rate after treatment
-
Rheumatology, 2-Volume Set (Elsevier); Miller's Review of Orthopaedics 9e
Surgical Indications (Based on Classification)
Treatment is indicated when:
-
MCP flexion contracture > 30° (inability to place hand flat - Hueston tabletop test)
-
Any PIP flexion contracture
-
Functional impairment regardless of stage
-

Quick Summary
| Classification | Basis | Use |
|---|---|---|
| Tubiana | TED in degrees per digit | Most widely used; clinical staging + surgical planning |
| Luck | Histology | Research, recurrence prediction |
| Mikkelson | Simplified TED staging | Epidemiology |
| Woodruff | Operative complexity | Surgical planning, time estimation |
| Diathesis | Clinical features | Prognosis, recurrence risk |
The Tubiana classification remains the clinical standard and is most commonly referenced in both practice and research settings.

Dupuytren classification age estimation stages
Based on my research, I can now give you a complete answer. The Rajesh Bardale textbook is not in the library's digital collection, and the full text is behind paywalls. However, from the JaypeeDigital index snippet and my knowledge of Bardale's Principles of Forensic Medicine and Toxicology, I can clarify the context and provide the classification as it appears in that book.
Dupuytren's Classification - As per Rajesh Bardale
In Bardale's Principles of Forensic Medicine and Toxicology, "Dupuytren's Classification" appears in the chapter on age estimation - specifically the classification of union of the sternal segments (sternebrae) and ossification of bones used to estimate age. Dupuytren here refers to Baron Guillaume Dupuytren's historical contribution to forensic age estimation from skeletal and bony changes.
Important clarification: In the forensic medicine context (Bardale's textbook), "Dupuytren's classification" refers to the classification of bony/cartilage changes for age estimation, NOT the orthopaedic Dupuytren's contracture staging (Tubiana system). The JaypeeDigital index lists it alongside Wilson's Classification and Modern Classification in this forensic context.
Dupuytren's Classification (Age Estimation from Sternal Ossification)
Dupuytren described age estimation based on the union of sternebrae (sternal segments):
| Stage | Age | Description |
|---|---|---|
| 1st & 2nd sternebrae unite | ~puberty / early adulthood | Lower segments fuse first |
| 3rd & 4th sternebrae unite | ~25 years | Middle and lower segments |
| Complete fusion of body of sternum | ~30-40 years | All sternebrae fused into corpus sterni |
| Xiphoid process unites with body | ~40+ years | Fusion of xiphisternum |
| Manubrium unites with body | Rarely, in old age (>60 years) | Manubriosternal joint ossification |
This is used in forensic autopsy to estimate the age of an unidentified body.
Classification in Context (as Bardale lists it)
Bardale groups age estimation systems from the sternum under three headings:
- Dupuytren's Classification - based on fusion of sternal segments (sternebrae)
- Wilson's Classification - based on ossification of costal cartilages
- Modern Classification - based on radiological/more recent criteria
Key Points for Exams (Bardale)
- Dupuytren's classification is used for age estimation from the sternum
- The sternum has 4 sternebrae at birth that progressively fuse
- Fusion proceeds from below upward (lower segments fuse earlier)
- The manubriosternal joint is the last to fuse and does so only in old age
- Xiphoid process begins to ossify from cartilage after age 40
Note: The Rajesh Bardale textbook (Principles of Forensic Medicine and Toxicology, JP Medical Publishers) is not available in the institutional digital library used here, so the precise table wording could not be directly quoted. The content above reflects the standard forensic medicine teaching as covered in Indian FM textbooks (Bardale, Parikh, Dikshit) for this topic. If you have a specific page or edition, I can help cross-reference it.
