The Process of Prosthetic Making and Fitting
A prosthesis, or artificial limb, is a custom-made device designed to replace a missing or damaged body part. Each prosthetic limb is tailored to the individual’s unique needs and body shape.
Step 1: Measurements
The prosthetist takes precise measurements of the patient’s body, ideally before amputation. This ensures the prosthetic limb closely matches the natural limb.
Step 2: Post-Operative Action
The prosthetist and surgeon collaborate to dress the surgical wound. A compressive garment is typically used to remove fluid from the residual limb, promoting healing and shaping the amputated stump.
Step 3: Post-Wound Healing
Once the wound has healed and swelling has reduced, the prosthetist creates a plaster mold or fiberglass cast of the residual limb. This cast is used to build a positive model of the patient’s limb, which is then modified to design the wearable interface.
Step 4: Final Fabrication
The prosthetic limb is assembled and shaped to fit the patient’s needs. Factors considered during design include:
– Patient’s overall health
– Muscle, tendon, and bone position in the residual limb
– Functional goals (e.g., daily use, walking, running)
– Gait pattern (for lower limb prosthetics)
– Weight-bearing requirements (for lower limb prosthetics)
Materials Used
Prosthetic materials vary depending on the patient’s needs, preferences, and budget. Common materials include:
– Thermoplastics
– Resin
– Carbon
– Silicone
– Aluminum
– Titanium
Customization and Adjustments
The prosthetic limb is customized to provide a natural appearance and feel. Adjustments are made over time to ensure optimal fit and function. Physical therapy helps patients learn to use their new limb and perform daily activities.
Advances in Prosthetic Technology
Modern prosthetics can be designed for specific activities, such as:
– Running
– Skiing
– Shooting a crossbow
– Eating with a fork
– Playing basketball
With ongoing advancements in technology and design, prosthetic limbs continue to improve, offering greater mobility and independence for individuals with amputations.
