Posterior iliac osteotomy for fixed pelvic obliquity
RE Lindseth
In nine children with a myelomeningocele and fixed pelvic obliquity due to
uncorrectable lumbosacral scoliosis, a bilateral posterior iliac osteotomy
was done and a wedge of bone was transferred form the low side to the high
side of the pelvis. This produced a mean correction of 14 degrees (41 per
cent) of the pelvic obliquity and a mean correction of the trunk list from
the midline of seven centimeters (69 per cent). Two to seven-year
follow-ups showed that the correction was permanent, without tendency for
the obliquity to return as long as the scoliosis did not progress. The
procedure resulted in several complications, including fracture of the
pelvis and transient sciatic-nerve palsy; however, it provided a means of
correcting pelvic obliquity that could not be corrected by standard
procedures.
