Resumen (ES)
We performed 186 procedures in 167 patients with leg length discrepancy. Proximal
and distal methaphyseal corticotomy was utilized. The rate of distraction was 1 mm per day.
The distraction started 10 days postop. We treated 114 femora and 69 tibiae, one humerus, one
ulna and one fibula. The average of lengthening was 54.4 mm and 15.9 percent of lengthening for
the bone. The healing index was 46.5 days/cm with 42.8 days/cm for femur and 50.3 days/cm for
tibiae. The etiology was divided in groups: poliomyelitis sequelae, 33.4%; congenital, 22.5%; infections,
11.4%; short stature, 10.5%; trauma, 7%; dysplasias, 7%; development dysplasia of the
hip, 6.1%; metabolic, 2.6%. The complication was divided in four groups and we found that the
major complication was present in the group with poliomyelitis sequelae and congenital problems. In
our study, we found that contractures and pin tract infections were the most common complication.
and distal methaphyseal corticotomy was utilized. The rate of distraction was 1 mm per day.
