Background:
Assessment of shoulder function is an essential part of clinical practice. Current scoring relies on multiple subjective and / or objective components. We present a single angular measurement, the coronal plane angle, which relates to the functional assessment of the shoulder.
Materials And Methods:
One hundred patients were prospectively enrolled and assessed using the Constant-Murley score and the Oxford shoulder questionnaire, and the coronal plane angle was measured for both symptomatic and asymptomatic shoulder.
Results:
NINE PATIENTS WERE EXCLUDED FROM THE STUDY: Four had apprehension and five were not able to get their hand to head. The mean coronal plane angle on the symptomatic side was +11.3 degrees and the asymptomatic side -1.5 degrees (P = 0.01). Pearson's correlation of 0.9 and 0.84 was demonstrated for the Constant-Murley and Oxford shoulder scores, respectively, with the coronal plane angle.
Conclusion:
The coronal plane angle is a single objective assessment and provides a simple alternative to shoulder assessment for the majority of patients.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
