The Schatzker classification system divides tibial plateau fractures into six types
- Schatzker I: lateral tibial plateau fracture, with minimal (<4mm) depression or displacement.
- Schatzker II: lateral tibial plateau fracture with fragment depression
- Schatzker III: compression fracture of the lateral (IIIA) or central (IIIB) tibial plateau
- Schatzker IV: medial tibial plateau fracture with split/depressed component
- Schatzker V: bicondylar (lateral and medial) tibial plateau fractures
- Schatzker VI: transverse tibial plateau fracture with metaphyseal-diaphyseal discontinuity (also known as Type C articular fracture in the AO classification)
1951 – Attempts at classifying tibial plateau fractures were first made in the 1950’s by Palmer
Common themes for these fractures were established at this time, including fracture of one condyle or bicondylar involvement and subchondral depression.
1979 – Joseph Schatzker published a formal classification system for tibial plateau fractures by using AP radiographs of a group of 94 patients. The emphasis on this classification system was to guide treatment with relation to the original fracture pattern and mode of injury
Many other classification systems for tibial plateau fractures have since been described including that from Khan et al. (2000), however the Schatzker and AO/OTA systems remain the two used most commonly today
- Does not include fractures in the coronal plane or others not seen on plain AP radiographs
- Tibial plateau fractures that were operatively managed had better outcomes than those that were managed non-operativley; but patients with a tibial plateau fracture and associated osteoporotic bone had poorer outcomes when managed operatively than non-operatively.
- Soft tissue injury is another management consideration for tibial plateau fractures, but it does not lie in the classification system put forward by Schatzker
- Interobserver reliability varies with the Schatzker classification as only plain radiographs are used. This may be improved by adding other imaging modalities, such as CT or MRI to the plain radiograph, but no current literature is sold on advanced imaging being a necessity for the purposes of the classification system on its own.
- In terms of surgical planning, the use of cross-sectional imaging are more accurate than the plain AP radiographs used in the Schatzker classification system
