Zdravkovic classification divides scapular fractures into three types according to their anatomical location.
Type | Description |
---|---|
Type I | fracture of the body of scapula |
Type II | fracture of the apophysis including the coracoid and acromion |
Type III | fracture of the supero-lateral angle including the neck and glenoid |
Gay et al. used a semiquantitative score to objectively assess the extent of lung fibrosis. In the study, each lobe was scored separately and mean of all lobes was used as a fibrotic, ground glass, and total score for each patient.
Alveolar score | Description |
---|---|
0 | no alveolar disease |
1 | ground glass opacity involving <5% of the lobe (minimal disease) |
2 | ground glass opacity involving <25% of the lobe |
Warrick classification of lung involvement in interstitial lung disease is a quantitative scoring method of disease extent and severity. The grading involves the following features of the disease:
Feature | Grading |
---|---|
Global disease extent | Estimated to the nearest 5% |
Extent of reticulation | Proportion of total disease extent |
Extent of ground-glass | Proportion of total disease extent |
Wells classification of lung involvement in systemic sclerosis is a quantitative scoring method of disease extent and severity. All lobes are scored independently. Maximum score for each lobe is 5.
Grade | Description |
---|---|
1 | Ground glass opacity alone |
2 | Ground glass opacity > reticular pattern extent |
3 | Ground glass opacity = reticular pattern extent |
4 |
Otosclerosis is a primitive dystrophia of the temporal bone that leads to abnormal bone growth. Veillon classification divides sites and extension of otosclerosis based on finding on HRCT of the temporal bone into 6 types.
Type | Description |
---|---|
Ia | isolated thickening of the footplate hypodensity |
Ib | isolated anterior fenestral hypodensity <1mm (AFH) |
II | isolated anterior fenestral hypodensity >1mm (AFH) |
The Sanders classification is based on CT evaluation of calcaneus in coronal plane. The classification was published in 1992 and it takes into account location and number of fracture lines. The image is evaluated in coronal plane where it shows the posterior articular facet in its widest (latero-lateral) profile, where the location of primary fracture line with relation to the posterior articular facet is determined (intra-articular fracture).
Type | Description |
---|---|
Type I |
Ideberg classification of glenoid fractures has five basic types. It is based on evaluation of
338 glenoid fractures and was published in 1995.
Type | Description |
---|---|
Type I | anterior glenoid rim fracture: avulsion fracture of the anterior glenoid rim IA: fragment size <=5mm IB: fragment size >5mm measured on the film |
Type II |
Odontoid fractures are classified into three types. Type III is not an odontoid fracture but rather fracture of the vertebral body.
Type | Description |
---|---|
Type I | avulsion fracture of the tip of dens (rare) |
Type II | fracture at the base of dens - most common (cca 2/3) |
Type III | fracture extends into the body of the vertebra, does not involve dens (cca 1/3) |
Three types of fracture of the base of the first metacapal bone (thumb) are distinguished by eponyms.
Type | Description |
---|---|
Winterstein | oblique extraarticular fracture of the base |
Bennett | oblique intraarticular fracture of the base with dislocation of the peripheral fragment due to lateral traction of the shaft by abductor pollicis longus |

The Gehweiler classification divides fractures of the first cervical vertebra into five types. Type III is also refered to as Jefferson fracture. The classical Jefferson fracture is a four part fracture, where both the anterior and the posterior arch is fractured twice, but fractures with two or three fracture parts may also occur.
Type | Description |
---|---|
Type I | fracture of the anterior arch |
Type II | fracture of the posterior arch |
