Stability of the elbow: osseous constraints.
The elbow is considered a complex joint, and thus the elements contributing to stability of the elbow are no less intricate. The soft-tissue and articular surfaces that provide stability to the elbow share the capacity as a function of joint position and loading configuration. The issue of soft-tissue constraints is dealt with elsewhere in this volume, and the focus of this discussion is that of the articular contributions. In this context, the radial head is defined as a secondary stabilizer to resist valgus force. The coronoid is clearly the most important articular stabilizer of this joint.
