First Step in Prosthetic Construction

Toronto’s Sunnybrook Centre for Independent Living (SCIL) has a 25-member team of prosthetists, technicians and other experts. SCIL helps complex trauma patients regain independence and mobility with customized prostheses and individualized rehabilitation.

Prostheses are made in the on-site lab. The first step in creating a new limb is to make a socket in the stump or residuum. The artificial body part attaches inside the socket. The prosthetist takes detailed measurements of the residuum and then creates a cast of it – similar to that for a broken limb. When that cast dries, plaster is poured into it to make a form of the limb. The form is then carefully smoothed down and filed until it becomes an exact replica of the residuum. The amputee is fitted with a test socket and a limb and learns to walk with this set before the definitive socket and limb are finalized.

Technician Paul Russell says there is “a bit of an artistic feel and flow,” as some amputees need their sockets to be very strong and others want them to be light. “You’re trying to walk the line between something that’s strong enough and something that is not too heavy.”

Patients often develop a strong, lifelong bond with their prosthetist. The more the experts get to know the amputees, the better they are able to create sockets that work for their lifestyle. Getting the artificial limb for the first time can be a life-changing experience.
