Longer residual limb lengths provide an increased lever arm.
Longer residual limbs may produce increased joint moments; the two may be
correlated. These correlations have not been evaluated in transfemoral amputees
during transitional movements. Correlations between residual limb length and
involved side joint moment could contribute to justification supporting maximal
residual limb length preservation. This study investigated possible correlations
between hip or knee moment and residual limb length. TECHNIQUE: Hip and knee
joint moments were determined while 21 transfemoral amputees performed sitting
and standing movements and then evaluated for correlation with residual limb
length. DISCUSSION: Residual limb length was not correlated with either knee or
involved side hip moments during sit to stand or stand to sit. Conversely, weak
inverse correlations (p < 0.05) existed between sound hip moment magnitude and
residual limb length. These correlations suggest that in community ambulating
transfemoral amputees, longer residual limb length could decrease sound hip
kinetic burden during transitional movement. Beyond correlations between residual
limb length and sound hip transitional movement kinetics, there are other
considerations in determining residual limb length during amputation. CLINICAL
RELEVANCE: This study examines relationships between lower limb joint moments and
residual limb length related to sit-to-stand and stand-to-sit activities. The results have implications for amputation surgery and rehabilitation.
