Going strictly on my somewhat dated experience as a Vocational Rehabilitation Counselor with medical terminology I would guess -- from the context -- that your phrase should read:
"the acetabulum was fixed into the pelvis, the femur in a primary femoral revision"
I don't have a clue regarding the spelling part of your question.
I am not familiar with the etiquette/limitations of legal/medical transcription. Is it possible/proper for you to contact the physician's office (through the court, if necessary, to avoid any appearance of impropriety) to ask for clarification?
