Nice lecture.. Am a student in a medical school, specializing in orthotics and prosthetics, and honestly.. I'd request you to do more of this lectures cause they are really helpful
Circumduction: additional reasons: 1. Not fully seated in socket (socket too tight) and making prosthesis effectively longer. 2. Medial boarder of socket is impinging, possibly due to inadequate adductor relief, adductor roll development, or in too far, and circumduction is more comfortable. 3. Gait habit, possibly because patient learned to walk with locked knee initially and doesn't trust a prosthetic knee that flexes, 4. Improper sagittal plane alignment, not accomodating hip flexion contracture so that knee flexion moment cannot be obtained at late stance, carrying over into swing phase, causing a longer leg requiring circumduction to clear. Lateral trunk bend: common; may be biomechanically necessary for many due to nature of most TFAs. A lot of this is from the loss of leverage from the normal attachment of adductors magnus and longus. If they are even attached. So then the abductors shorten due to loss of antagonistic function and the pt is left with weak abductors. Careful coronal plane socket and prosthetic alignment can often reduce the external hip adduction moment. Ivan Long's observations are important to understand proper TF prosthetic alignment. Of course a true abduction contracture is difficult.

Hi,I'm studying this feld like you.!.😅
Thank you I much appreciate because it was difficult to catch up during lectures but on watching I've been able to make ends meet 🤗 from Kenya

Excellent explanation on gait deviations
Thanks from Canada!!
This is such a boring topic for me to read alone. You made it very easy to remember and understand. Great
Thanks!
With just first and single video I hit subscribe. Thank you so much. Can't thank enough
Thank you soo much, this will really help with my upcoming board exams!
thank you for your good explanation again sir.
Can u please explain the other deviations like,vaulting,wide base,hip hicking etc plzzzzz
excellently explained. thank you!
Excellent video, I do have short residual limb
Great lecture! Keep them coming..
thank you sir
excellent
