Hands-Off and Hands-On Casting Consistency of Amputee below Knee Sockets Using Magnetic Resonance Imaging
The connection between the residual limb and prosthetic device is crucial to its success. Amputees themselves have stated socket fit is the most important characteristic of the prosthesis.
Plaster of Paris is applied either directly to the residual limb or to the covering elastomeric liner. Prosthetists can shape the plaster during casting using either use their hands (Hands-on) or an air pressure bladder can be used. When the methods were compared and reviewed in an MRI scan, it was shown that there was no significant difference between the two methods for transverse cross section surface area or for cast length.
The authors clarified that the intra cast differences were less than one layer of socking, which is commonly used by amputees due to normal residual limb size fluctuations. Although, there were general less variances seen in these measurements using the hands-off method and it is suggested that this could be improved by use of a special designed casting device. > From: Safari, et al., ScientificWorldJournal (2013) 486146.
