The differential diagnosis of the restriction in a patient with shoulder, elbow and hip joint limitations who had mental retardation and bipolar psychiatric disorder was evaluated. Development of heterotopic ossification (HO) due to akinetic rigidity syndrome in a patient with mental retardation and bipolar psychiatric disorder will be discussed. The reason of pain, swelling, warmth and motion limitation in the shoulder, elbow and hip joints, based on clinical observations, laboratory results and bone scintigraphic data was in accordance with HO. Bone scintigraphy showed that the reason of excessive activity increase in these areas was due to HO, which developed as a result of rigidity and immobility. Treatment of extrapyramidal signs lessened rigidity but continuation of motion limitation due to ossification was observed although there was a decrease compared to previous findings. Shoulder, elbow and hip are the sites where HO frequently develops and periarticular ossification due to immobilization can explain the reason of such clinical presentation.
