Restraint techniques used to control young people are being reviewed by the Justice Department after a report by the Commission for Children and Young People and Child Guardian highlighted "systemic issues" at the state's two centres in Brisbane and Townsville.
The report examines the cases of six young detainees who suffered serious injuries between September 2009 and November 2010, including a dislocated shoulder and fractured upper arm; four fractured wrists; and a fractured forearm.
One of the youngsters, who suffered a broken right wrist after being put in transport wrist locks by two workers, was just 148cm (4ft 10in) tall and weighed only 28kg.
The technique involves immobilising a young person's forearm and then bending their hand inwards, causing medium to high levels of pain.
Youth Affairs Network of Queensland executive director Siyavash Doostkhah said the report was "disturbing", especially with the State Government prepared to open Queensland's first two boot camps.
Mr Doostkhah welcomed the recommendations but said "an urgent independent inquiry" was needed, which should investigate excessive use of solitary confinement.
A Department of Justice spokesman said the recommendations were being addressed.
