Systems, methods, and software are provided for assessing manufacturing errors of a prosthetic socket to facilitate a clinical assessment of the socket. The embodiments disclosed herein may align and compare a manufactured socket shape to a desired socket shape to determine whether clinically significant errors are present in the manufactured socket. A mean radial error (MRE) may be calculated and compared to a set threshold. If the MRE falls below the threshold an interquartile range (IQR) may be calculated and compared to an IQR threshold. If the IQR falls below the IQR threshold, surface normal angle errors (SNAE) may be calculated and plotted to the surface model. If the SNAE plot does not include closed contour regions, the socket may proceed to patient fitting. If the MRE or IQR thresholds are exceeded, or if the SNAE plot indicates closed contour regions, the socket may be reshaped accordingly, prior to fitting.

The inside of the multifunctional prosthetic scarves are prepared with polyurethane templates that allow the wearer to attach strips of real human hair onto them. The scarves give a realistic appearance and a firm secure fit. The multifunctional prosthetic scarves fit well without a tight or pressured feeling on the scalp reducing humidity build up on the scalp which prevents the scalp from sweating and causing irritation to the skin. The multifunctional prosthetic scarves' comfortable and distinguished feel allows the wearer to adjust the appearance by providing an appearance of having a full head of hair. Other head coverings provide a simplistic appearance for the person who is going under chemotherapy but may be uncomfortable and appear artificial. Although the velcro hair may appear to provide some hair it is a small amount of hair it provides. These headwear accessories are constraining and do not allow the scalp any breathing room causing the scalp to sweat. The scalp becomes irritated and often produces a restless desire to scratch. All of these products make the scalp sweat or itch unlike the multifunctional prosthetic scarf that will fit well without a tight or pressured feeling while preventing the scalp from sweating and itching.
