Which term indicates a partial displacement of a bone from its joint?

The term that indicates a partial displacement of a bone from its joint is "subluxation." This condition involves a situation where the bone is not fully out of its normal position within the joint, meaning that while the articulation is compromised, the bone remains partially in place. This can result in pain and instability in the joint, but it is less severe than a complete dislocation, where the bone is entirely displaced from its joint socket.

Dislocations involve a total displacement and typically require significant intervention to correct, while fractures refer to breaks in the bone itself, not displacement within the joint. Strains involve the stretching or tearing of muscles or tendons, which is unrelated to bone displacement. Understanding these distinctions is vital for recognizing the nature of joint injuries and the appropriate treatment they may require.
