The surfactal Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) constitute a modern method with multiple biomedical applications. This article presents a comparative-dissection study with different anterior lumbar spine cadaveric specimens, based on previous contribution advances. Two new unalike specimens are selected for CAD-CAM—Specimen 1 and Specimen 2. Improved programming for lumbar spine CAD is developed from former publications. Objective results demonstrate the amount of biomedical-surgical practical/ functional that can be obtained from computational surfaces of these anatomical samples. The selected cadaveric specimens 1 and 2 are evaluated and compared anatomically and functionally after software implementation. The programming-software method(s) explanations with series of demonstrative images constitute the formal surfactal-computational resulting part. The designed computational optimization program for anatomical imaging of specimens is proven be efficacious. Consequent anatomical deductions for surgical applications are got from every image, by using appropriate subroutines and designed patterns. Out coming demonstration of the particular anatomy for any individual is determined. The singular-patient difficulties that can be found at tools manufacturing and/or surgical theatre intervention are verified. Explanations of optimization applications in future biomedical surgery, surgical robotics integrated systems, and tools manufacturing form an important part of results. Projection to surgical robotics, spinal prostheses, orthopedics, spine-rehabilitation apparatus and Forensic Robotics [Casesnoves, 2020] constitute concrete consequences.
