What term is used for an incomplete or partial dislocation?

The term "subluxation" describes an incomplete or partial dislocation of a joint. In this condition, the joint surfaces lose their normal alignment but remain in partial contact. It's important to distinguish this from a complete dislocation, where the joint surfaces are entirely separated, which is typically referred to simply as a dislocation or luxation.

Subluxation can lead to instability in the affected joint and may result in pain and limited range of motion. This term is commonly used in clinical contexts, especially in rehabilitation and therapeutic settings, where understanding the nuances of joint injuries is essential for effective treatment.

The other terms do not accurately describe a partial dislocation, as "dislocation" and "luxation" indicate a complete separation of joint surfaces, while "fracture" pertains to a break in a bone rather than a relation between joint surfaces. Understanding these distinctions is crucial for providing appropriate care and fitting therapeutic shoes for individuals with joint issues.
