OBJECTIVE: To describe the results of surgical treatment of Scheuermann's disease by the posterior approach. METHOD: A descriptive, retrospective, longitudinal study in which patients with Scheuermann's disease, treated surgically by the posterior approach at the Hospital de Traumatologia y Ortopedia [Hospital for Traumatology and Orthopedics] "Lomas Verdes" IMSS. The Cobb method was used to measure the kyphosis in all the patients, of T5-T12. The surgical technique used was vertebral shortening by the Ponte osteotomy technique, at the apex of the deformity, accompanied by transpedicular instrumentation and posterior arthrodesis. RESULTS: Five patients were included; three men and two women, with an average age of 16.6 years. The initial average kyphosis was 76º, which was corrected to 42º after surgery. Blood loss was 590 ml, with a surgery time of 3 hours. Three patients were submitted to neurophysiological monitoring. No neurological lesion was found. There was no loss of correction at 6 months of evolution. CONCLUSIONS: The vertebral shortening technique with posterior instrumentation eliminates the use of the anterior approach to release the anterior longitudinal ligament. Osteotomies by the Ponte technique make the spine more flexible, and together with pedicular instrumentation, correct the deformity and preserve the correction over time.

Objective: This study aims to evaluate the outcome of surgical treatment of congenital torticollis in our hospital. Methods: We collected the medical records of all patients diagnosed with congenital torticollis in the last 3 years at Shriners Hospital, Mexico City. The cases of congenital torticollis treated with surgery were selected and we evaluated the type of surgical technique, bleeding, time of surgery and complications, as well as the associated diagnoses of hip dysplasia. Results: We found 11 patients, of whom 7 met the inclusion criteria. Three women and four men with mean age of 10.7 years, five of whom had right, and two left side affections. All were surgically treated, five with unipolar and two with bipolar release. The surgery time was similar in both techniques and no complications were found in any of the groups. In two cases there were associated diagnoses, Klippel-Feil syndrome and congenital talipes equinovarus (CTEV) in one and psychomotor retardation in another. No association was found with hip dysplasia. All patients had improved range of movement and head tilt. There were no complications related to the surgical procedure or need for reintervention in our patients. Conclusions: Surgical treatment of congenital torticollis by uni- or bipolar release is an effective and safe method for these patients, presenting aesthetic and functional benefits.
