question is : translate all of the bold faced medical terms into simple language as if you are explaining it to a patient or to someone who may not understand medical terminology and incorporate these simple translations into your story.

Laura had just recently recovered from an automobile accident in which she incurred numerous injuries including greenstick fractures of her left femur, a slipped femoral capital epiphysis, subluxation of the pubic symphysis, chondromalacia patellae, and compound fractures of the tibia, fibula and calcaneus.
Fortunately for her, there was no tendinopathy or ligamentous sprain of the upper appendicular skeleton and she had excellent strength in shoulder adduction bilaterally. This helped her ambulate with her crutches.
Jim was anxious to meet Laura at the gym. They had shared many hours of rehabilitation and encouragement between them. Jim had been diagnosed with ankylosing spondylitis and he was determined not to have kyphoscoliosis like his father. Jim was also an aspiring body builder who longed for hypertrophic skeletal uscles. Of course, this level of desire compounded with his exercise regimen and previous medical history produced osteoarthritic changes in the vertebral column with the development of exostoses that increased his kyphosis.

He was afraid of scoliosis occurring. There was no apparent exaggerated lordosis overall but there were signs of intervertebral disk herniations forming. While driving to the gym, Laura witnessed an automobile accident between an ambulance and a delivery truck. During the accident Laura experienced tachycardia. She could feel her own symptoms exacerbating and hoped that there was no possibility of a thrombus dislodging from her injuries caused by a deep vein thrombosis with the already critical situation. Laura had recently learned that she was anemic and hypovolemic and had been taking medications to help offset this condition.

Right now she was the “best” person to take charge and she had to determine what to do.

The driver of the ambulance was wearing a Medical Alert bracelet that read “anti-coagulants”. He was exsanguinating and yelled out to Laura that the box in the back of the rig contained a cardiac donor organ that was urgently needed across town at Mercy Hospital.

Laura, called Jim who had been expecting her and asked him if he could help her. Jim and Laura escorted the donor organ to Mercy Hospital. Actually it was a great idea to call Jim, since Laura was not ambulating well yet and Jim had great speed. When Jim met Laura, she was tachypneic and really needed assistance herself.

Her gait was virtually ataxic at this point due to weakness. Another ambulance came to rescue the injured parties.
Jim gave the donor organ to the cardiologist for typing and cross matching the tissue to offset the possibility of hemolysis and subsequent organ rejection and/or organ failure.

It was going to be given to a young father who following cardiac catheterization was diagnosed with 90% blockage in the right main coronary artery. His subsequent cerebrovascular angiogram was not just a screening tool.


He was experiencing amaurosis fugax and it was thought he may be showering emboli from his cardiac valves, possibly the mitral valve. Although neither Laura nor Jim actually ever made it to the gym to work out, they both felt that the day they themselves had already had an intense workout.
