Results and Discussions
This paper focuses on a new method of using data obtained from CT images
combined with digital CAD and rapid prototyping model for surgical planning and
this new application enables the surgeon to choose the proper configuration and
location of internal fixation of plate on humerus bone during orthopaedic surgery.
The method gives rise to various advantages and disadvantages. Oka et al. [
8
] found
that the process can be used in various studies of biomechanics, computational stress
analysis. Design of optimal training regimens to minimize the risk of injury can also
be performed. The verification required from the biological experiments for the
structure analysis makes the process slightly difficult. The study of parameters and
loads of the bone makes the process a time-consuming one.
The limitations of this study are that the soft tissue considerations were not
employed. The strengths of this work are that the resultants are very close to the
previous works performed using RP. In conclusion, the virtual bone that we
studied can be used as prototype model for the studies regarding humerus fracture
with application in medical researches.
