Accurate roentgenographic determination of lumbar flexion-extension.

abstract：BACKGROUND:There are few data on the types of procedures orthopaedic oncologists perform in their first years of practice. Because fellowships are graduating fellows each year and the number of tumor patients is limited, defining the practice patterns of early-career orthopaedic oncologists may help diminish early empl...
