Definition:
The capsular pattern is a proportional limitation of the passive movements of the
elbow:
There is usually more limitation of flexion than of extension.
As a rule, the pro- and supination are not limited; in a severe arthrtitis
both rotations may be equally painful at the end of range.
Flexion> Extension
Examples:
| FLEXION | EXTENSION | PRONATION | SUPINATION | |
|---|---|---|---|---|
| SLIGHT CAPSULAR PATTERN | - 20° | - 10° | Normal | Normal |
| SEVERE CAPSULAR PATTERN | - 60° | - 45° | ++ at end of range | ++ at end of range |
