PROSTHETICS

An amputation of any kind can be a life altering event. We understand that navigating the process of receiving a prosthesis can be difficult and overwhelming. It is our goal to work with each patient to support them in achieving the best outcome with the use of their prosthesis. At the heart of our business, we want to ensure that each patient is well taken of. We offer comprehensive information and guidance to help patients and caregivers make informed decisions during the prosthetic fitting process.

What is a prosthetist?2025-06-09T23:24:25+00:00
  • A prosthetist is a healthcare professional that is knowledgeable in the field of designing and building artificial limbs and other devices for those missing a body part or body parts.
What is a prosthesis?2025-06-09T23:24:32+00:00
  • A prosthesis is an artificial device that is intended to replace a missing body part. Individuals who have experienced limb loss due to injury, disease, or congenital conditions can benefit from prosthetic limbs.
What does prosthetic mean?2025-06-09T23:24:56+00:00
  • Although the words prosthetic and prosthesis are similar, there is a difference. Prosthetic refers to the field of medicine that focuses on designing and building artificial limbs to help people gain or improve mobility.
What are the different types of prostheses?2025-06-09T23:25:05+00:00
  • Lower Extremity
    • Above Knee (transfemoral)
      • A transfemoral prosthesis is an artificial leg that attaches above the knee.
    • Below Knee (transtibial)
      • A transtibial prosthesis is an artificial leg that attaches below the knee.
    • Below Ankle (syme)
      • A Symes prosthesis is an artificial foot that attaches below the shin.
  • Upper Extremity
    • Above Elbow (transhumeral)
      • A transhumeral prosthesis attaches to the patient above their elbow but below the shoulder.
      • There are two types of transhumeral prostheses – passive and active.
        • Note: Like a transradial prosthesis, a transhumeral arm can be passive or active, but the elbow’s absence can make restoring the patient’s functionality more challenging.
    • Below Elbow (transradial)
      • A transradial prosthesis attaches to the patient directly below their elbow.
      • There are two types of transradial prostheses – passive and active.
        • Passive: This style of prosthesis is only for cosmetic purposes and does not restore the function or movement of the missing limb. A passive prosthesis can be fabricated using lifelike silicone to mimic the look of a natural arm.
        • Active: This style of prosthesis is meant to restore the function of the missing limb. There are different types of active transradial prostheses. The first is a cable-operated prosthetic arm. This type of device uses a harness connected to the shoulders of the patient to allow the patient to control the prosthesis manually. This type of prosthesis is also referred to as a body-powered prosthesis. Another type of an active prosthetic arm is a myoelectric system. This system involves an electronic device that operates through electrical impulses generated by your muscles. This system is more involved, but it is a viable option for many transradial amputees.

 

 

What factors determine the type of prosthesis provided?2025-06-09T23:25:19+00:00
  • Level of Amputation. The different levels of body site amputations are listed below:
    • Lower Extremity
      • Toe Amputation
      • Foot Amputation
      • Below Knee Amputation
      • Knee Disarticulation
      • Transfemoral Amputation
      • Hip Disarticulation
    • Upper Extremity
      • Hand or Partial Hand Amputation
      • Wrist Disarticulation
      • Below Elbow Amputation
      • Above Elbow Amputation
      • Shoulder Disarticulation
      • Forequarter Amputation

 

  • Condition of Amputated Limb. After an amputation, a patient’s residual limb may experience a variety of conditions that can affect healing, comfort, and functionality. Any of these conditions can alter the prosthetic fitting process, but we work with the patient and their medical providers to ensure that the patient is receiving the most appropriate care with the current condition of their residual limb in mind.
    • Contractures: This condition can occur after an amputation where the soft tissues near the amputation site shorten and tighten, limiting joint movement.
    • Edema: This term refers to any swelling of the residual limb due to a buildup of fluid in the patient’s body. There are multiple causes of edema, and managing the size of the patient’s residual limb may be a bit difficult after a recent amputation, but we have many remedies to assist the patient with reducing the volume of their residual limb.
    • Muscle Atrophy: This condition is when a patient loses muscle mass after an amputation. This could be caused by underuse of the muscles in their residual limb. Muscle atrophy can also affect other muscle groups that are being used to overcompensate for the missing limb.
    • Phantom Limb Pain: This condition is caused by nerve endings at the amputation site sending pain signals to the brain, which interprets them as if the limb is still there. The pain can range from mild to severe and can last from a range of seconds to hours, sometimes even longer. The pain may be intermittent, but some amputees do have continuous phantom limb pain. Phantom limb pain can feel like tingling, throbbing, or sharp pins and needles. The pain can range from mild to severe, and may be constant or intermittent, depending on the patient.
    • Residual Limb Pain: There are many causes that can lead to residual limb pain. Some of the causes for this pain are excessive skin irritation, infection, nerve damage, poor blood supply, and pressure sores.
    • Skin Issues: There are different types of skin issues that may occur after an amputation or from wearing an ill-fitting prosthesis. Two of these issues are skin irritation and pressure ulcers. Skin irritation may come in the form of redness, chafing and blistering of the residual limb. Also, there can be pressure ulcers that develop from prolonged pressure on a certain area of the residual limb.

 

  • Functional Ability Pre- and Post-Amputation. (Lower Extremity Only) When designing and fabricating a prosthesis, a patient’s functional ability, or activity level, is taken into consideration to ensure that the patient receives a prosthesis that best meets their lifestyle and activity level. To meet insurance requirements, the patient must have an established activity level, or potential to reach a certain level in a reasonable time. For consistency, insurance companies across the board use a system for different activity level qualifications, these are also known as K-Levels. The K-Level scale ranges from K0 – K4. A description of each level will be listed below:
    • Level 0: The patient does not have the ability or potential to ambulate (walk) or transfer safely with or without assistance and a prosthesis does not enhance their quality of life or mobility. When a patient is qualified at this level, it is highly unlikely that insurance will cover the cost of a prosthesis.
    • Level 1: The patient has the ability or potential to use a prosthesis for transfers or ambulation on level surfaces at fixed cadence, typical of the limited and unlimited household ambulator.
    • Level 2: The patient has the ability, or potential, for ambulation with the ability to transverse low level environmental barriers such as curbs, stairs or uneven surfaces. This level is typical of the limited community ambulator.
    • Level 3: The patient has the ability, or potential, for ambulation with variable cadence. This level is typical of the community ambulator who has the ability to transverse most environmental barriers. The patient may have vocational, therapeutic, or exercise activity that demands prosthetic utilization beyond simple locomotion.
    • Level 4: The patient has the ability, or potential, for prosthetic ambulation that exceeds basic ambulation skills. The patient must exhibit high impact, high stress or high energy levels. This activity level encompasses the prosthetic demands of a child, active adult, or athlete.

 

  • The Patient’s Desired Hobbies and Goals. One of the goals of wearing a prosthesis is to help a patient complete their Activities of Daily Living (ADLs) and live a fulfilling life. Before designing a prosthesis, one of our prosthetists will consult with the patient about their lifestyle. They will discuss their activities before and after their amputation, and any goals they would like to achieve with the use of their prosthesis. Goals vary based on the patient and what type of amputation they’ve had (upper extremity vs lower extremity). Examples of common ADLs are listed below:
    • Personal Care: This includes activities such as bathing, toileting, and dressing oneself.
    • Personal Hygiene: This includes activities of grooming, such as brushing hair and brushing teeth.
    • Mobility: This includes walking confidently, making transfers, and climbing stairs safely.
    • Eating: This includes preparing and eating meals independently, or with minimal assistance.
    • Communication: This includes making phone calls and sending electronic messages. This also includes writing by hand.
    • Household Management: This includes maintaining a clean living space. Examples of this would be washing dishes, doing laundry, and running errands like grocery shopping and picking up mail.
    • Medication Management: This includes managing the scheduling and intake of medications as prescribed or directed.

 

  • Patient Presentation. Before and during the process of a patient being fit with a prosthesis, our prosthetist will take into account the patient’s presenting concerns and any co-existing health conditions. These factors will play a role in the final design of a patient’s prosthesis.
    • Patient Concerns: The process of designing a prosthetic limb is not solely in the prosthetist’s hands. We value patient feedback, and genuinely take into consideration any concerns or preferences they may have regarding the prosthetics process. If feasible, we will gladly work with the patient to design a prosthesis that they will love. Some common topics that patients present with, are concerns about the comfort level of a prosthesis, personal customizations, durability, ease of use, functionality and technology features available.
    • Medical Conditions: Our doors are open to patients of all health statuses. There are many causes of amputations and we are here to meet patients where they are. Some of the leading medical conditions that lead to amputations are cancer, congenital conditions, diabetes, infections, nerve damage, non-healing wounds, trauma, and vascular diseases. While the patient may see us for their prosthetic needs, it is important for them to have a comprehensive care team that can monitor any conditions that they may have.

 

  • Insurance Coverage.
    • Insurance coverage varies from patient to patient. Even patients who have the same insurance carrier may have different health insurance plans which have different benefit details. Our knowledgeable patient coordinators are always happy to talk to patients to explain their benefits and any requirements that their insurance carrier may have to ensure coverage. Please visit our BILLING page for more details on this topic.
What is a prosthetic leg?2025-06-09T23:25:50+00:00

What are the benefits of a prosthetic arm?2025-06-09T23:27:20+00:00
  • Patients have reported many benefits of wearing their prosthetic arms. Our goal is to provide a prosthesis that will change the patient’s life for the better. Examples of benefits of a prosthetic are below:
    • Enhanced Independence: After receiving a prosthetic arm, many patients are able to perform tasks on their own, providing them with greater independence in life. For those who have had a limb previously, they appreciate that a prosthetic arm can restore their ability to perform daily activities, such as eating, dressing, and using tools.
    • Enhanced Mobility: A prosthetic arm can enhance a patient’s overall mobility. A prosthetic arm is meant to mimic the movement and coordination of a natural limb. This allows patients the ability to engage in activities of daily living.
    • Improved Mental Health: After wearing a prosthetic arm, many patients report a boost in confidence, and an enhanced self-image. These effects can lead to an overall better mental health status.
    • Improved Quality of Life: Gaining functionality from wearing a prosthetic arm means that patients have the opportunity to participate in life in ways they may not have been able to previously. This includes engaging in social interactions, work and recreational activities.
What are prosthetic components?2025-06-09T23:27:25+00:00
  • There are many components involved in a finalized prosthesis. Although many components are similar, there are differences between lower extremity and upper extremity prosthetic components. Below you will find detailed information on each component involved in a completed prosthetic device.
What are the components of a lower extremity prosthesis?2025-06-09T23:27:31+00:00
  • Socket
    • A prosthetic socket is a crucial component of a prosthesis. It provides a stable base for the patient’s prosthetic leg, distributing weight and supporting the patient during movement. Each socket is custom made to fit the patient’s residual limb. A prosthetic socket is made with many materials. When selecting the materials, we take many factors into consideration. We choose lightweight materials to help reduce fatigue when the patient is using the prosthesis. Although we use lightweight materials, we also ensure that they are durable and can withstand daily wear and tear. Ultimately, the choice of material depends on the specific needs of the patient and their lifestyle and activity needs.
  • Suspension Mechanism
    • The job of a suspension system in a prosthesis is to ensure the patient’s comfort, stability, and functionality while wearing their prosthesis. The suspension system is responsible for keeping the patient’s prosthetic leg securely attached to their residual limb, preventing it from slipping and shifting during movement. The suspension system also helps to distribute the patient’s body weight evenly, reducing pressure points and maximizing comfort.
  • Knee Joint (above knee prosthesis only)
    • A prosthetic knee joint serves many essential purposes for above knee prostheses. The prosthetic knee joint is designed to replicate the natural movement of a biological knee. This allows for flexion and extension during walking, running, and other activities. The knee joint also provides stability while standing and walking, helping the patient to maintain balance and prevent falls. As with other prosthetic components, the prosthetic knee joint supports the patient’s body weight, distributing pressure to reduce stress on their residual limb. Some prosthetic knees can even adapt to different terrains and walking speeds, allowing patients to explore a variety of environments with more confidence.
  • Shank (Pylon)
    • A pylon serves as the main structural component that connects the socket to the foot. Pylon has the necessary strength and stability to support the patient’s weight as they use their prosthesis. The pylon also helps the patient to maintain proper alignment. It ensures that the foot is positioned correctly in relation to the residual limb and the ground. Proper alignment is essential for an efficient and steady gait. The pylon works in conjunction with other prosthetic components to distribute the force that is exerted when the patient is walking or running. This assists in reducing stress on the residual limb. Pylons are adjusted to meet the patient’s needs, activity level and type of prosthetic foot used. We always look for the most appropriate set up when designing and fabricating prosthetic devices.
  • Foot
    • A prosthetic foot is a vital component to a lower extremity prosthesis. It has many functions that are critical to the success of the overall prosthesis. A prosthetic foot has the job of supporting the patient’s weight while they are standing, walking, and performing other activities. The foot absorbs impact and distributes the force evenly across the ground. This reduces stress on the patient’s residual limb, while also providing stability to the entire prosthesis. Prosthetic feet are designed to replicate the movement of a biological foot. This allows for smooth transitions between the different phases of walking or running. Some prosthetic feet can adapt to different terrains, and some can even propel the patient forward with each step. Ultimately, the foot chosen to be a part of the final prosthesis depends on the patient’s needs, preferences and activity level. If the patient’s needs or activity level changes, the foot on the prosthesis can be re-evaluated and changed if necessary.
What are the components of an upper extremity prosthesis?2025-06-09T23:27:39+00:00
  • Socket
    • A prosthetic socket is the base of an upper extremity prosthesis. It connects the residual limb to the prosthetic arm. Each socket is custom made to fit the patient’s residual limb. A secure fit is crucial for the patient’s comfort by minimizing pressure points and preventing skin irritation. A secure fit also allows for effective control of the prosthesis. A prosthetic socket helps to distribute pressure evenly across the residual limb during activities, reducing stress and potential injury. We strive to design and fabricate prosthetic sockets that allow for more natural movements, contributing to an overall improvement in function for the patient.
  • Suspension Mechanism
    • The suspension system of a prosthetic arm is vital for keeping the prosthesis firmly attached to the residual limb. The suspension system provides stability, allowing patients to perform activities without fear of their prosthesis shifting or falling off during use. The suspension system helps distribute stress away from any single area of the residual limb within the socket, preventing discomfort, pressure sores, friction, and irritation. A proper suspension system allows for natural movement patterns, giving the patient the ability to participate in daily activities more effectively.
  • Elbow Joint (above elbow prosthesis only)
    • The key role of a prosthetic elbow joint is to allow for flexion and extension of the prosthetic arm. This replicates the natural movement of a patient bending and straightening their arm. Since the elbow joint provides movement, it enhances the overall functionality of the prosthetic arm, allowing patients to reach, lift, and manipulate objects more effectively. A prosthetic elbow helps distribute the weight of the prosthetic arm evenly, reducing stress on the patient’s residual limb and improving their comfort level. Along with the suspension mechanism, a prosthetic elbow joint contributes to the stability of the patient’s prosthetic arm during activities. It ensures that the arm stays in the appropriate position when needed. The elbow joint is often used in conjunction with control systems, such as myoelectric units, which allow the patient to operate the prosthetic arm with electrical signals from their muscles. Some advanced prosthetic elbows can adapt to different activities and movements. This allows patients to switch between different tasks without any delay. Overall, an elbow joint is a very important component of an upper extremity prosthesis.
  • Forearm
    • The forearm of an upper extremity prosthesis serves many key functions in the design of the overall prosthesis. The forearm connects the prosthetic socket to the wrist joint and terminal device, creating a complete and functional prosthetic arm. By providing strength and structural integrity to the prosthetic arm, it helps to support the weight of the terminal device and any objects the patient may be handling. The forearm component also allows for natural movements from the patient, granting them the ability to perform tasks such as lifting, reaching, and manipulating objects. It is important that the forearm is in proper alignment. This is crucial for effective movement and function of the prosthetic arm, ensuring that the wrist and terminal device operate harmoniously with the patient’s movements.
  • Wrist Joint
    • A prosthetic wrist joint provides range of motion by allowing for rotational and flexion movements. These movements enable the patient to position their terminal device appropriately for different tasks. By enabling movements such as turning the palm up or down, the wrist joint improves the overall functionality of the prosthetic arm. This helps facilitate everyday activities of daily living such as eating, writing, and using tools. The wrist joint is crucial in providing stability to the terminal device. It ensures that the terminal device remains steady while handling objects. This is highly important for tasks that require precision. The wrist joint also helps distribute the weight of the terminal device and any objects being held by the terminal device. This helps the patient by reducing strain on their residual limb, and enhancing their overall comfort while using their prosthesis.
  • Terminal Device
    • A terminal device can come in a variety of devices. It can be a hand, hook, or specialized tool. Terminal devices are chosen based off of the needs and lifestyle of the patient. The purpose of a terminal device is to allow the patient to have direct interaction with objects. The device allows patients to grasp, hold, and manipulate objects. Most terminal devices are designed to replicate the natural movements of a biological hand. This type of design enhances the patient’s ability to perform tasks that require fine motor skills.
  • Cosmetic Cover
    • The primary purpose of a cosmetic cover for a prosthetic arm is to improve the appearance of the arm and hide mechanical components of the prosthesis. A cosmetic cover can make a prosthetic arm look more natural and less mechanical. This can help boost the patient’s confidence and self-esteem. Cosmetic covers can be designed to match the patient’s skin tone. Cosmetic covers can be very detailed and include details such as hair, freckles, and more, allowing for a more personalized experience. Although not the primary purpose, a cosmetic cover can also provide a bit of protection from dirt and debris entering the prosthetic arm.
  • Control System
    • All parts of a prosthetic arm are important, but the control system plays a crucial role in its functionality and usability. The control system allows the patient to operate the prosthetic arm effectively. The control system enables them to make movements such as grasping, lifting, and positioning objects. The system enhances the precision of the prosthetic arm’s movements. This allows for fine-tuned movements and a more natural interaction with objects. Control systems are tailored to meet the specific needs of the patient. We can make adjustments in speed, sensitivity, and response based on the patient’s activities and personal preferences. Some control systems have feedback features that provide patients with information about their arm’s position or grip strength. This feedback helps them improve control and effectiveness of their prosthesis.
  • Battery (myoelectric prosthesis only)
    • The primary purpose of a battery for a patient’s prosthetic arm is to provide the necessary power for electronic components such as motors, sensors, and control systems. In myoelectric prostheses, the battery powers the motors that control the movement of the joints, such as the elbow and wrist, and also powers the terminal device. Modern prosthetic batteries are designed to be rechargeable and efficient. This allows patients to effectively manage their power supply, and ensure that the arm remains operational during daily activities. The batteries are also designed to be lightweight and compact, lessening the overall weight of the prosthetic arm.
What do I bring to my first appointment?2025-06-09T23:31:59+00:00
  • What you need to bring to your first appointment depends on what we’ll be seeing you for. There are different requirements for orthotic appointments versus prosthetic appointments.
    • Shoes/Foot Orthotics:
      • Please bring your current shoes that you wear on a regular basis. This would include athletic shoes, walking shoes, and/or work shoes, etc.
      • Please bring your current foot orthotics, if you have any. This would include custom molded foot orthotics, over-the-counter foot orthotics, heel lifts, metatarsal pads, etc.
      • Please bring socks to wear with your shoes.
      • Please be prepared to discuss your symptoms, daily activities and lifestyle needs. This will help our practitioner determine the best shoes and foot orthotics for you specifically.
    • Orthotic Device – Ankle Foot Orthosis (AFO):
      • Please be prepared to talk about your symptoms and any functional goals you may have. (Ex: difficulty walking, tripping while walking, experiencing ankle instability, etc.)
      • Please bring socks to wear with your AFO.
      • Please bring shoes that you plan on wearing with your AFO. If you’re unsure, it doesn’t hurt to bring 2 pair of shoes. Please avoid slip-on shoes, slides, or shoes without support.
      • Please bring any mobility aids that you currently use. This will help our practitioner observe your gait with and without the use of the mobility aid. (Ex: cane, walker, crutches, etc.)
    • Orthotic Device – Knee Orthosis (KO):
      • Please be prepared to talk about your symptoms and any functional goals you may have. (Ex: pain, instability, locking when walking, etc.)
      • Please bring shorts or loose-fitting pants to provide easy access to your knee for our practitioner during the evaluation and fitting of your knee brace.
    • Prosthetic Devices:
      • If you’ve already been fit with a prosthesis, please bring it with you to your appointment. Even if it’s broken, outdated, uncomfortable, and you don’t wear it, bringing it to your appointment will provide us with helpful insight on how to build your new prosthesis.
      • Please be prepared to talk about your symptoms and any functional goals you may have.
      • Please bring any prosthetic supplies you are currently using. This would include prosthetic liners, sleeves, socks, shrinkers, etc.
      • Please bring any mobility aids that you currently use. This will help our practitioner observe your gait with and without the use of the mobility aid. (Ex: cane, walker, crutches, etc.)
      • For lower extremity prosthetic patients: Please bring shorts to change into, if necessary.
      • For upper extremity prosthetic patients: Please bring a short sleeve top or tank top to change into, if necessary.
    • For any appointment, if you have any questions or concerns, it’s best to come with them written down so you don’t forget to ask about any of them.
    • Some patients prefer to bring a caregiver, friend, or family member to help them communicate and remember what was discussed during the appointment. Also, if you require physical assistance, it’s best to bring whoever helps you so that they can be informed on the process as well.
