Assessment of spinopelvic morphology in adolescent with idiopathic scoliosis : comparison with normal adolescents
Notice bibliographique
Résumé
Introduction and aims:The aims of this study were to assess the clinical, radiological and functional outcomes following the treatment of a lumbar Chance fracture and to analyze the spectrum of associated abdominal injuries as seen in the seat belt syndrome.Method: All patients diagnosed with L1-L4 Chance fractures at the British Columbia Children's Hospital were included in this study.Patient data, injuries, treatment and complications were collected from hospital charts.A review of all available spinal radiology including pre-treatment, post-treatment and follow-up x-rays, CTs and MRIs was done to measure pre-treatment, post-treatment and follow-up kyphosis angles.We have also described and calculated a Chance fracture deformity index.Patients were seen at followup to assess for range of motion, tenderness and neurologic status.Furthermore, a functional outcome questionnaire by the American Academy of Orthopaedic Surgeons (AAOS) Pediatric Instruments was completed by the patients.Results: Between December 1984 and February 2001, 27 patients aged 3-17 years were treated for lumbar Chance fractures.The mean age at injury was 11.1 years.There were 17 females and 8 males.All injuries occurred as a result of a motor vehicle accident.Seventeen were rear-seat passengers, and 8 were front-seat passengers.Of the 25 patients, 17 were treated surgically.Of these 17, 7 were treated with either pedicle screws or laminar hooks and rods, 4 with intersegmental spinous process (ISP) wires alone, 2 with sublaminar wires and 4 with a combination of screws/hooks, rods and ISP wires.Of the 8 patients treated conservatively, 4 were treated with a hyperextension cast and 4 were treated with a hyperextension brace.Twelve patients had abdominal injuries.Three cases involved abdominal arterial vascular trauma.Significant improvement in intra-vertebral kyphosis, segmental kyphosis and vertebral kyphosis remodelling (6.5 v. 4) was noted in the operative group compared with the nonoperative group.The diseasespecific AAOS Lumbar Spine Questionnaire scores were poor for pain and disability: 29.22 (26.41-31.98);but the SF-36 scores for both MCS and PCS were within the normal range: 47.79 (44.03-51.54)and 47.71 (42.59-52.82),respectively.Conclusion: An abdominal and spinal CT must be taken when presented with a Chance fracture with abdominal symptoms.Injury type and kyphosis angle are the main factors that aid in treatment planning in pediatric lumbar chance fractures.A purely soft-tissue injury or a kyphosis angle greater than 20r equires surgical intervention.
