FAQs: Prosthetic Components for Medical Applications

Prosthetic components are precisely engineered mechanical devices which provide ambulation for people with limb loss, specifically transtibial (below-knee), transfemoral (above-knee), transradial (below-elbow), and transhumeral (above-elbow) amputations. Prosthetic knee joints can range from being mechanical, microprocessor controlled, to more advanced configurations. Other components include ankle-foot mechanisms which provide dorsiflexion and plantarflexion control, pyramid adapters which align and adjust prosthetic limbs, socket adapters which connect prosthetic limbs to patient sockets, pylon tubes which provide structural support, shock absorption, and stabilization, and foot components which incorporate dynamic response, multi-axial designs, and more. Other adjunct components include joint rotation adapters, elbow joints, wrist rotators, and terminal devices related to upper limb prosthetics, which are all integrated into prosthetic limbs.

Titanium Ti-6Al-4V provides exceptional strength-to-weight ratio enabling lightweight prosthetics reducing energy expenditure by 20 to 30 percent during ambulation, excellent biocompatibility for skin contact, corrosion resistance to perspiration and environmental exposure, and fatigue strength supporting millions of gait cycles. Aluminum 7075-T6 and 6061-T6 deliver lightweight construction with adequate strength for prosthetic frames and adapters, cost-effectiveness, excellent machinability for complex geometries, and corrosion resistance with anodized finishes. Stainless steel provides maximum strength for high-stress components including knee joint pins and fasteners, wear resistance at articulating surfaces, and proven durability. Carbon fiber composites offer ultimate weight reduction with strength comparable to aluminum at 40 percent of the weight, energy storage and return for dynamic prosthetic feet, and design flexibility for patient-specific applications.

Complex three-dimensional shapes are produced in the CNC milling of knee joint housings, ankle mechanisms, and socket adapters with built-in alignment features. CNC turning creates cylindrical pylon tubes, joint pins, and rotation adapters. Concentricity of the parts is achieved within 0.002 inches. Coordinate drilling creates mounting hole patterns with position accuracy of ±0.005 inches. Topology optimization with FEA software. 30 to 50 percent of structural material is retained while weight is significantly reduced. Cold composite machining and diamond tooling prep the carbon fiber components. Anodizing adds a lustrous finish to aluminum while it provides protection against corrosion.

Mounting hole position tolerances of ±0.002 enable alignment and interchangeability of components, bearing bore tolerances of ±0.001 facilitate smooth articulation of the joint, and ±0.002 concentricity which is required to achieve rotation of parts. Flatness of 0.005 inches is controlled on mounting surfaces and overall dimensions are controlled to ±0.010 inches for compatibility of components. Critical interface dimensions ensure a socket standardized to the prosthesis and a patient socket, it is controlled within ±0.003.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.

All components are manufactured under ISO 13485 certified quality management systems for medical devices, ensuring full compliance with FDA regulations for Class I and Class II prosthetic devices, European Medical Device Regulation (MDR) requirements, ISO 10328 structural testing for lower limb prosthetics including static and cyclic loading, complete traceability from raw material through final product, and adherence to Good Manufacturing Practices ensuring patient safety, mobility, and quality of life for individuals with limb loss.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

Standard prosthetic adapters and pylon components take 8-14 business days while custom patient specific joints and mechanisms take 3 to 5 weeks and include design optimization, machining, and surface treatment. In 7 to 10 days we can complete patient fitting trial components which streamlines the process for prosthetic fabrication and delivery.

Absolutely. We create specialized components that enhance energy return and impact absorption to accommodate running and sporting activities. For swimming and other water sports, we use corrosion-resistant and sealed materials to fabricate water-resistant components. For pediatric users, we incorporate adjustable growth features. For elderly users, we design lightweight components that minimize energy expenditure. We create heavy-duty components for occupational use that support loads over 150 kilograms. Advanced prosthetics include microprocessor-controlled joint housings. We also design custom geometries for bilateral amputees, hip disarticulation, and congenital limb differences

Correctly mounted interfaces within ±0.002 inches guarantee alignment and preservation of the correct position of the prosthetic. Thus, compensatory gait patterns are avoided and energy expenditure is reduced. The joint surfaces articulated with friction coefficients of <0.1 which allowed the prosthetic limb to mimic the movement of a natural joint. The prosthetic limb’s weight was reduced by 30 to 50 percent, as strategic material removal lightweight optimization was applied. This reduced the metabolic cost of walking by 15 to 25 percent. Optimized geometry prevented under designed stress concentration of stressful regions leading to prolonged component life of over 3 million gait cycles (5 years of normal use). The load bearing components were designed to support 5 times body weight during running and jumping, thus, the materials provided were adequate and of good quality. The durable, corrosion-resistant finish that withstands damage from perspiration, water, and the environment was impressive. Excellent modular design and quality manufacturing allowed components to be interchanged and alignment adjusted, improving the fit and function of the prosthetic limb, thus, improving the quality of life of limb loss gaiters.
