The aims of present study were (1) to determine changes in kinematic and kinetic
variables at 3 and 12 months after open reduction and internal fixation (ORIF) of
pelvic ring fracture and (2) to determine the factor(s) associated with gait
disorders that correlate with gait parameters measured at 12 months after
surgery. Nineteen patients with pelvic ring fractures underwent ORIF and examined
at 3 and 12 months postoperatively. The study also included a similar number of
age-matched control subjects. Peak hip abduction angle, peak hip extension moment
in the stance, peak hip abduction moment, and peak ankle plantarflexion moment at
3 months after ORIF were significantly lower than the respective control values.
At 12 months, complete recovery was noted in peak hip abduction moment and peak
ankle plantarflexion moment, whereas the recovery in peak hip abduction angle and
peak hip extension moment in the stance was partial. The existence of
neurological lesions and strength asymmetry of hip abductor and adductor at 3
months post-ORIF correlated with decreased peak hip abduction moment after ORIF.
Our results highlighted characteristic gait patterns up to 12 months after ORIF
for pelvic fracture, and these patterns correlated with neurological lesion and
weakness of hip abductor and adductor muscles.
