Understand the classification of joints based on their movement: Joints are categorized as synarthrodial (immovable), amphiarthrodial (slightly movable), and diarthrodial (freely movable).
Recognize that amphiarthrodial joints allow limited movement and are typically found in areas requiring stability and slight flexibility, such as the pubic symphysis or intervertebral discs.
Compare the options provided: An immovable joint (synarthrodial), a freely movable joint (diarthrodial), a slightly movable joint (amphiarthrodial), and a hinge joint (a type of diarthrodial joint).
Identify that the correct answer corresponds to the amphiarthrodial joint, which is slightly movable, such as the pubic symphysis.
Conclude that the injury most likely affects the slightly movable joint, as this matches the definition and characteristics of an amphiarthrodial joint.
