BK Prosthetics
These are used to manage daily limb volume fluctuations and fine-tune socket fit.
Prosthetic socks
Preventing this contracture for AK amputees is a major goal in early recovery.
Hip flexion contracture
This type of therapy helps reduce swelling and prepare the limb for prosthetic fitting.
Compression therapy (shrinkers or ace wraps)
This is the leading cause of lower extremity amputations in the United States.
dysvascular disease
This is the leading cause of upper extremity limb loss in the United States.
Trauma
This K-level is typical of a limited community ambulator who can traverse low-level barriers.
K2
This widely used socket design includes the ischium within the brim for a “bony lock.”
Ischial containment socket
This type of phantom discomfort can feel like burning, cramping, or electrical shock.
Phantom limb pain
These amputations typically do not require surgical amputation because the limb difference occurs before birth.
Congenital limb deficiencies
This UE amputation type accounts for ~90% of all upper extremity amputations.
Partial hand
This socket transfers weight through the patellar tendon and other pressure-tolerant areas.
PTB (patellar tendon bearing) socket
This suction system uses no interface and relies on compression of soft tissue to form a seal.
Skin-fit suction
This wrapping pattern helps avoid “choking” and improves limb shaping.
Figure-eight pattern
This cancer, most common in long bones, is a leading diagnosis requiring surgical amputation.
Osteosarcoma
Patients who do heavy manual labor often prefer this type of prosthesis for durability and control.
Body-powered prosthesis
This K1 foot is durable, simple, and has a cushioned heel but no articulation.
This amputation removes the entire femur and suspends from the iliac crest.
Hip disarticulation
This test helps identify hip flexor tightness, which can contribute to lumbar lordosis and back pain.
Thomas test
This foot deformity associated with neuropathy is often initially misdiagnosed as infection and worsens with continued walking.
Charcot foot
This high-level amputation is the most complex to control because it eliminates glenohumeral movement.
Shoulder disarticulation
This suction system uses a ring and one-way valve and requires alcohol spray to don.
Seal-in Suspension
This knee brakes under load to prevent buckling and is ideal for slower walkers.
Weight-activated stance-control knee
This amputation level causes loss of anterior lever arm, leading to increased knee extension during loading response.
Partial foot amputation
This complication—bone forming in soft tissue—is common in trauma amputations and requires surgical removal.
Heterotopic Ossification (HO)
This type of body-powered system is driven primarily by the CMC joint.
