Mr L Had His Left Leg Amputated at the Hip

Mr. L had his left leg amputated at the hip 20 years ago due to a farming accident. Although he was unable to maintain his work as a farmer, he was hired at the local grain elevator for assisting with record keeping. He has been functioning well at his job until he recently developed scoliosis. The scoliosis in his particular case is:

A) a progressive breakdown in the bone due to demineralization caused by a genetic disorder, which is often not diagnosed until middle age
B) most probably caused due to postural difficulties brought about by utilization of his prosthetic device
C) related to his lack of acceptance of his condition and refusal to comply with medical therapy
D) easily corrected with cutting of the opposing musculature of the spine
