Which of the following structures are important to anterior/posterior postural observation and analysis?

The vertebral column is assessed posteriorly for lateral curvature indicative of scoliosis, which is a key abnormality detectable only from this view; the scapulae are evaluated for bilateral symmetry and balance, including winging or unequal height. These two structures provide the most clinically meaningful reference points for identifying frontal plane postural deviations during an anterior/posterior assessment.

The glenohumeral joint and elbow/wrist are not primary landmarks for anterior/posterior postural analysis; they are more relevant to lateral or functional movement observation.

The vertebral column is assessed for lateral curvature (scoliosis) rather than rotation in an anterior/posterior view, and elbow/wrist rotation is not a standard focus of this observation plane.

Glenohumeral joint rotation is better evaluated during lateral or functional assessment, not specifically during anterior/posterior postural observation.
