What percentage of trauma-related amputations are UE? - 🧠ANSWER
✔✔68%
,How many people in the US are living with limb loss? - 🧠ANSWER ✔✔2.1
million
Reasons for transfemoral amputation (AK) - 🧠ANSWER ✔✔complications
from BKA, infection from TKA, failed vascular reconstruction
Knee disarticulation - 🧠ANSWER ✔✔Amputation through the knee joint;
femur intact
transtibial amputation - 🧠ANSWER ✔✔below knee amputation; most
common as it preserves more joints
Syme's amputation - 🧠ANSWER ✔✔surgical removal of the foot at the
ankle joint with removal of the malleoli
Transmetatarsal amputation - 🧠ANSWER ✔✔removal of the midsection of
the metatarsals, typically following unhealed ulcer on palmar MT head
Lisfranc amputation - 🧠ANSWER ✔✔amputation at tarsometatarsal joint
Transverse terminal limb deficiency - 🧠ANSWER ✔✔What we think of as a
surgical amputation (transfemoral, transradial)
,Intercalary defects - 🧠ANSWER ✔✔absence or hypoplasia of a middle
section of long bone, such as a femur or radius, with normal distal
structures such as the hand, foot, or digits
Transverse intercalary limb deficiency - 🧠ANSWER ✔✔phocomelia,
hypoplastic foot or hand (vestigial digits)
Longitudinal terminal limb deficiency - 🧠ANSWER ✔✔pre-axial, central,
post-axial -- list missing bone
Longitudinal intercalary - 🧠ANSWER ✔✔proximal femoral focal deficiency
How do you determine level of amputation? - 🧠ANSWER ✔✔- lowest level
that will heal
- lowest level that provides adequate soft tissue for covering
- lowest level that will provide pain free residual limb during WBing
Myodesis - 🧠ANSWER ✔✔attaching muscle to bone
Myoplasty - 🧠ANSWER ✔✔refers to attachment of anterior and posterior
compartment muscles to each other over end of bone
Transtibial surgical procedure - 🧠ANSWER ✔✔- long posterior
