Upper & Lower Limb Prosthetic Process - Macy O&P
Prosthetics are our passion at Macy O&P. We utilize 3D scanning, printing, and CAD software to measure and design the best fitting devices for our patients. We specialize in both lower and upper extremity prostheses. This includes myoelectric and microprocessor controlled prostheses, as well as specialized prostheses for heavy duty use, swimming, and running.


What makes up a prosthesis?
The most common type of amputation that we treat at Macy O&P is that of a below the knee (BK), or transtibial amputation. A BK prosthesis has 4 important components:
1) Socket – The interface that is customized to the shape and size of the patient’s residual limb so that it can surround and house it.
2) Pylon – This piece connects the socket to the foot. Pylons can look like a long pipe, can be cosmetic, or even a low- profile connecting component.
3) Foot – A prosthetic foot aims to mimic a human foot and help patient achieve their goals. Every amputee has different goals so matching a foot to help achieve those goals and functional level is important. Some feet work great for stability with transfers where other designs are more
4) Suspension – How the prosthesis stays attached to patient. Some options include, but are not limited to, pin locking, suction, or even a landyard strap.
