Incarceration and institutionalized are different words with similar meanings. The end result is being deprived of one's freedom and forced to live in adverse conditions.
I was in the foster care system for a duration of my childhood. At age 8 I was sent a AA (Abusive Assholes) foster home. I was screwing around in the garage (like many kids do) and I spilled turpentine. The AA Parents beat me senseless and broke my right arm as punishment for my transgressions.
After several hours in the ED which included an asthmatic attack and an arm cast I was taken to a juvenile care facility. I was placed into a room and I was still in agonizing pain from the broken arm. I was cold, alone and frightened. I had very little sleep when the door was opened. I was ordered to get on my feet and follow the guard to an adjoining examination room.
The guard ordered me to undress. I was still shaken. I couldn't take the fear anymore. I sat down on the floor and started crying. A few moments later some kind of health care provider entered the room, looked down at me and said "I don't have time for this. Luke, help me get this little bastard undressed. We need to give him an exam. He has bruises in addition to the broken arm. Dot the I's and cross the T's." They both picked me up. Luke held me from behind while the woman took my shoes, socks, sweatpants and underwear off. Luke then released me and told me to remain still. I was screaming out of fear. Then the scissors were used to cut off my undershirt. Luke replied " You are one damn skinny kid. Now do as the nice lady tells you or you're gonna have trouble, get it?"
The not so nice lady barked at me to step on the scale. She recorded my height and weight then told me to sit on the table. My blood pressure and pulse were taken. She looked at me and said "You have bruises on your chest and back in addition to that broken arm. Did they touch your private areas or rear end? Tell me right now." I was still crying but I managed to shake my head no. Then the two of them held me down on my stomach. My buttocks were spread open and inspected momentarily then in went the thermometer. Although it seemed like an eternity, it was removed within a few minutes.Then she had me sit up and gave my upper body a brief exam of the heart and lungs. I was a train wreck at this point, still sobbing and shaking. "Ok mister time for a shot. You need to calm down and this will help you sleep. By the time you are through eating breakfast you will be quiet and stupid. Now back on your stomach and don't force me to give this to you. I complied, got my shot, got dressed, had breakfast and was sent back to my room. Things didn't get much better during my stay. 9 more months of hell.
