Also know as a CPO, American Board for Certification (ABC) Certified Prosthetist Orthotist, professional specializing in fitting prosthetic & orthotic devices.

Dynamic alignment
Adjusting prosthesis to maximize amputee’s gait.

Edema
Increased fluid in tissue causing swelling.

Endoskeletal Prosthesis
Prosthesis that gains its strength from an internal pylon (pipe) composed of modular adjustable components sometimes covered by a soft cosmetic cover.

Ertl Procedure
Below knee amputation technique which surgeon will bridge the distal Tibia and Fibula with a bone graph. Once healed the distal end can tolerate weight loading.

Exoskeletal prosthesis
Prosthesis that gains its strength from a hard outer surface, typically plastic, non adjustable but more durable. GAIT TRAINING- Learning how to walk with prosthesis

Femur Bone
Bone in thigh

Fibula
Smaller and thinner outside bone lower leg below knee.

Fibula head
Upper lateral protrusion on the Fibula.

Forequarter
arm, shoulder, Clavicle, and Scapula removed

Gait
Walking pattern of person.

Humerus Bone
Bone from shoulder to elbow

Hyperextension
Extending angle of joint past normal.

Immediate Post-Operative Prosthesis

Interface
Surface that comes in contact with patients skin

Ischial containment
Above knee amputee socket which will contain patient’s pelvic butt bone, aiding in weight bearing and controlling socket for a more efficient gait.

Ischial Tuberosity
Pelvic butt bone where patient sits.

KAFO
Knee/ Ankle/ Foot/ Orthosis

Keel
Internal structure of prosthetic foot that gives it strength and/or energy responsive characteristics

K Level
Medicare requires the physician to categorize an amputee's potential activity level by designating a K-level. That K-level will limit an individual to certain componentry dependent upon their potential activity level. Categorized K Level 0-4.

Kyphosis
Patient has a humpback condition caused by a spinal curvature.

Lateral
Away from the midline of body.

Liner
Material used as an interface to offer comfort and skin protection usually consisting of gel, foam, or flexible thermoplastic.

Lordosis
Lumbar spinal curvature.

Lower extremity
Lower leg from pelvis to toes

LSO
Lumbo/ Sacral/ Orthosis

Malleolus
Predominant medial and lateral bones of ankle

Medial

Myodesis
Amputation surgical technique which muscles are tied to the bone.

Myoelectric arm
Upper extremity prosthesis which muscular signals are read by electrodes in socket, converting signal to activate and function electric hand and elbow.

Neuroma
Nerve bundle that grows in a network and usually causes pain

Also known as BRACE, external device applied to limit or assist motion or correct deformities of human body.

Patella
Knee cap

Peripheral Vascular Disease
Also known as PVD, disease of blood vessels

Permanent prosthesis
Prosthesis which appears cosmetic and/or anticipated will be used once residual limb has matured.

Pes Planus
A foot flat arch

Phantom pain
Pain that was in limb prior to amputation, patient still feels the pain after limb is removed.

Phantom Sensation
Also known as GHOST SENSATIONS, patient still feels limb that has been amputated. Some feel cramping, itching, toes curling but limb is not there.

Pistoning
Residual limb slipping up and down inside the prosthetic socket, usually due to residual limb being smaller than socket.

PLY
Thickness of sock, the more ply the thicker the sock (Ex. 1-ply, 2-ply, 3-ply, 4-ply, 5-ply)

Bone in lower arm between wrist and elbow connected to thumb.

Range of motion
The amount of movement in a joint also known as ROM.

Residual limb
Also known as STUMP, the remaining portion of limb after amputation.

Revision
When the residual limb is surgically modified. (Ex. Removal of sharp boney prominence, shorten residual limb for better vascular supply etc.)

Rigid dressing
Post operative dressing usually manufactured out of plastic, fiberglass cast, or plaster to create a socket fit applied after amputation to controls swelling and protect residual limb.

Scoliosis
S shaped curvature of spine

Socket
Component of prosthesis which contains the residual limb.

Stump shrinker
