A 12-year-old boy is brought to the clinic by his concerned parents. The boyâs forearm is bowed, and his parents are confused as to the possible diagnosis and treatment options. You notice that the right forearm of the child is bowed ulnarwards and is shorter compared to the left forearm. The pronosupination is markedly decreased on the right side but is also limited on the left side. The patient has a good grip, pinch, and grasp. He is neurologically intact as well.
The parents say that they first noticed the deformity around 6 or 7 years ago, and the mother informs you that she had noticed a hard bump on the forearm. She has recently noticed another bump on his right leg. The child does not complain of pain and is using both of his hands quite well. The parents were informed by a previous physician that the child has Madelungâs deformity and are concerned that the disease is now involving other areas of his body.
You order a radiograph of the forearm. The anteroposterior radiograph is shown (Slide 1). The childâs skeletal radiograph survey is also presented (Slide 2 and Slide 3).
Which of the following is not true regarding the possibility of malignant degeneration in this child:
A 12-year-old boy is brought to the clinic by his concerned parents. The boyâs forearm is bowed, and his parents are confused as to the possible diagnosis and treatment options. You notice that the right forearm of the child is bowed ulnarwards and is shorter compared to the left forearm.

The parents say that they first noticed the deformity around 6 or 7 years ago, and the mother informs you that she had noticed a hard bump on the forearm. She has recently noticed another bump on his right leg. The child does not complain of pain and is using both of his hands quite well.

Figure 39 shows the AP radiograph of a 62-year-old man with degenerative osteoarthritis secondary to trauma. History reveals that he underwent total elbow arthroplasty 3 years ago. He continues to report instability and constant pain. A complete work-up, including aspiration and cultures, is negative. Treatment should consist of removal of the components and**

Figure 27 shows the radiograph of a 26-year-old man who sustained a closed head injury and a closed elbow dislocation 6 weeks ago. Examination reveals 65 degrees to 115 degrees of flexion, and intensive physical therapy has resulted in no improvement.

During an anterior approach to correct thoracolumbar scoliosis, there is a sudden decrease in somatosensory-evoked potential (SSEP) and motor-evoked potential (MEP) signals. Correction maneuvers have not been attempted when signals go down. All neuromonitoring and anesthesia concerns have been addressed, and the measured abnormalities persist. What is the likely reason behind the neuromonitoring abnormalities?
