[Analysis of life quality on patients with thoracolumbar fractures]. / Análisis de calidad de vida en pacientes con fracturas toracolumbares.

Background: Patients with thoracolumbar fractures with TLICS 4 classification are at the limit of surgical fixation with regards to conservative treatment; however, results in our environment are not known, which is why this study has innovative characteristics. Objective: To determine the quality of life in patients with TLICS 4 thoracolumbar fractures using traditional fixation with regards to no fixation in a third level hospital. Material and methods: A cohort prospective study was carried out in patients with TLICS 4 classification thoracolumbar fractures using traditional fixation with regards to no fixation in beneficiaries from the Mexican Institute for Social Security. The SF-12 instrument, which assessed quality of life, was administered; age, sex, days of hospitalization, time of spinal cord injury were searched in the patients' medical history. It was used descriptive and inferential statistics using Student's t or Mann-Whitney U. Results: 20 patients participated and 9 had traditional fixation (45%). All patients had type E spinal cord injuries according to the International Standards for Neurological Classification of Spinal Cord Injury. Mean age of non-fixation was 42.2 ± 12.9 and of fixation 44.9 ± 10.2; in non-fixation 6 (67%) were male. The quality of life score was 29.1 ± 0.9 in the conservative treatment and 28.7 ± 1.3 in the surgical treatment, p < 0.462. Conclusions: No differences in quality of life were observed in patients with TLICS 4 thoracolumbar fractures using traditional fixation with regards to no fixation.

Introducción: los pacientes con fracturas toracolumbares con clasificación TLICS 4 se encuentran en el límite de la fijación quirúrgica con respecto al tratamiento conservador; sin embargo, resultados en nuestro medio no son conocidos, por lo que este estudio tiene características innovadoras. Objetivo: determinar la calidad de vida en pacientes con fracturas toracolumbares clasificación TLICS 4, mediante fijación tradicional con respecto a no fijación en un hospital de tercer nivel. Material y métodos: estudio de cohorte prospectiva en pacientes con fracturas toracolumbares clasificación TLICS 4 mediante fijación tradicional con respecto a no fijación en población derechohabiente del Instituto Mexicano del Seguro Social (IMSS).

Is There an Association With Spino-Pelvic Relationships and Clinical Outcome of Type A Thoracic and Lumbar Fractures Treated Non-Surgically?

BACKGROUND: The objective was to evaluate if there is an association of the spino-pelvic relationships and the global spinal alignment with the outcome of AO type A injuries treated nonsurgically. METHODS: This is a retrospective case series. Patients treated nonsurgically for AOSpine type A fractures (T1-L5) with at least 1 year follow-up identified. A standing antero-posterior and lateral 36-inch radiographs and measures of spino-pelvic relationships and sagittal alignment were obtained, as well as clinical assessment using the visual analog scale, the Short-Form 36 (SF-36) questionnaire, the Oswestry Disability Index (ODI), and labor status. RESULTS: Twenty-two patients with 33 fractures were included (L1 was the most injured level with 18.2%). There were 17 men (77.2%) and the mean age was 47.1 years. Follow-up ranged from 12 to 60 months (mean of 27.8 months). There were 22 type A1 (66.7%), 3 type A2 (9%), 6 type A3 (18%), and 2 type A4 (6%) fractures. The ODI ranged from 4% to 58%, with a mean of 24.4%. The SF-36 physical health score ranged from 23 to 82.25 (mean 49.59), and the mental health score ranged from 14.75 to 94.25 (mean 63.28). No association was identified between the spino-pelvic measurements, global alignment, and patient-reported outcomes. CONCLUSIONS: Type A fractures had a clinically relevant amount of long-term disability even when surgical treatment is not required. Spino-pelvic relationships and final global spinal alignment did not associate with outcome measurements.

Evaluation of the safety and reliability of the newly-proposed AO spine injury classification system.

OBJECTIVE: To evaluate the safety and reliability of the new AO Classification, a recent classification system for Thoraco-Lumbar Spine Trauma (TLST). DESIGN: Retrospective study. METHODS: We applied the new AO system in patients with TLST treated according to the TLICS. Two researchers classified injuries independently. Eight weeks later, the classification was repeated for intra and inter-observer agreement evaluation. To evaluate safety, we correlated the treatment performed based on the TLICS with the newer AO classification obtained. RESULTS: Fifty-four patients were included in this study, with a mean follow-up of 363.8 days. Twenty-three neurologically intact patients were initially treated conservatively. Their mean TLICS was 1.78 (1-4 points). Four patients underwent late surgery. Thirty-one patients were treated surgically. Their average TLICS was 7.22 points (4-10 points). Agreements in the four independent evaluations according to AO groups and subgroups were of 64.8% (35/54) and 55.5% (30/54) respectively. Kappa index for groups A, B and C was 0.75, 0.7 and 0.85 respectively. Kappa index for subgroups ranged from 0.16 to 0.85. Regarding safety, thirty (57.6%) patients with total subgroups agreement were analyzed. All patients with fracture in groups B and C underwent surgical treatment and patients in group A received surgery according to neurological status or failure of conservative treatment. CONCLUSION: The newer AO spine classification demonstrated good reliability at the level of groups. Subgroups demonstrated worse and varying reliability. Although the safety analysis was limited due to the low level of total concordance among all evaluations, patients from group A can be treated conservatively or surgically, whereas those from groups B and C are treated surgically.

Thoracolumbar Injury Classification and Injury Severity Score System: A Literature Review of Its Safety.

Study Design Systematic literature review. Objective The Thoracolumbar Injury Classification and Severity Score System (TLICS) is widely used to help guide the treatment of thoracolumbar spine trauma. The purpose of this study is to evaluate the safety of the TLICS in clinical practice. Methods Using the Medline database without time restriction, we performed a systematic review using the keyword "Thoracolumbar Injury Classification," searching for articles utilizing the TLICS. We classified the results according to their level of evidence and main conclusions. Results Nine articles met our inclusion and exclusion criteria. One article evaluated the safety of the TLICS based on its clinical application (level II). The eight remaining articles were based on retrospective application of the score, comparing the proposed treatment suggested by the TLICS with the treatment patients actually received (level III). The TLICS was safe in surgical and nonsurgical treatment with regards to neurologic status. Some studies reported that the retrospective application of the TLICS had inconsistencies with the treatment of burst fractures without neurologic deficits. Conclusions This literature review suggested that the TLICS use was safe especially with regards to preservation or improvement of neurologic function. Further well-designed multicenter prospective studies of the TLICS application in the decision making process would improve the evidence of its safety. Special attention to the TLICS application in the treatment of stable burst fractures is necessary.
