Sockets Manufactured by CAD/CAM Method Have Positive Effects on the Quality of Life of Patients With Transtibial Amputation

Patients with amputation need prosthesis to comfortably move around.
One of the most important parts of a good prosthesis is the socket. Currently,
the most commonly used method is the traditional socket manufacturing method,
which involves manual work; however, computer-aided design/computer-aided
manufacturing (CAD/CAM) is also being used in the recent years. The present study
aimed to investigate the effects of sockets manufactured by traditional and CAD/CAM method on clinical characteristics and quality of life of patients with
transtibial amputation.
DESIGN: The study included 72 patients with transtibial
amputation using prosthesis, 36 of whom had CAD/CAM prosthetic sockets (group 1)
and 36 had traditional prosthetic sockets (group 2). Amputation reason,
prosthesis lifetime, walking time and distance with prosthesis, pain-free walking
time with prosthesis, production time of the prosthesis, and adaptation time to
the prosthesis were questioned. Quality of life was assessed using the 36-item
Short Form Health Survey questionnaire and the Trinity Amputation and Prosthesis
Experience Scales. RESULTS: Walking time and distance and pain-free walking time
with prosthesis were significantly better in group 1 than those in group 2.
Furthermore, the prosthesis was applied in a significantly shorter time, and
socket adaptation time was significantly shorter in group 1. Except emotional
role limitation, all 36-item Short Form Healthy Survey questionnaire parameters
were significantly better in group 1 than in group 2. Trinity Amputation and
Prosthesis Experience Scales activity limitation scores of group 1 were lower,
and Trinity Amputation and Prosthesis Experience Scales satisfaction with the
prosthesis scores were higher than those in group 2. CONCLUSION: Our study
demonstrated that the sockets manufactured by CAD/CAM methods yield better
outcomes in quality of life of patients with transtibial amputation than the
sockets manufactured by the traditional method.
