Introduction:

Identify the progress of patients who had internal tibial torsion and were treated with surgical correction, performing derotating tibial osteotomy.

Material and methods:

Retrospective study included patients diagnosed with abnormal gait-causing internal tibial torsion in which conservative treatment failed, between January/2016 and January/2019.

Results:

12 patients with an age range of 4.3-17.8 years of whom nine patients (75%) were female and three (25%) male; the weight range was 12.36-59.30 kg; among the associated pathologies were found myelomeningocele three patients (25%), cerebral palsy two patients (16.6%); the postoperative hospital stay of six patients (50%) one day, five patients (41.67%) stayed two days, and three days only one patient (8.33%); three patients (25%) minor complications and one patient (8.33%) major complications; progress was good in 11 patients (91.67%) and regular in one patient (8.33%).

Conclusion:

It is the first series communicated in Ecuador, where reference is made to the use of tibial osteotomy in the supramaleolar area, combined with Kirschner pin fixation, correcting internal tibial torsion in children where conservative treatment failed, resulting in a safe procedure and favorable results in the evolution of gait, including patients with neuromuscular disease and under five years of age.
