Complications of polyarticular JIA include skeletal abnormalities such as increased size of epiphyses, accelerated bone age, narrowed joint spaces, swan-neck and/or boutonniere deformities, joint subluxation, and cervical spine involvement.

Difficulty extending the spine may create a problem for intubation prior to surgery, so anesthesiologists need to be informed of the patient's diagnosis. Cervical spine radiography (in flexion and extension) may help to screen for potential difficulties during induction of anesthesia. High-level subluxation is a potential complication.
