Outcomes of spinal cord injury following cervical fracture in ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis (DISH): A prospective cohort study / Lesión medular cervical traumática en pacientes afectados de espondilitis anquilosante y DISH. Estudio comparativo prospectivo

Introduction The ankylosed spine is prone to increased fractures risk even after minor trauma. The lower cervical spine is most frequently injured, and fractures of the ankylosed spine tend to precipitate spinal cord injury (SCI). The objective of the current study is to assess the incidence, management, and outcomes of patients with ankylosis of the spine sustaining a cervical fracture with associated SCI over a 7-year period. Material and methods Prospective cohort study. Patients referred to the institution with a cervical fracture associated with SCI on a background of AS or DISH from 2009 to 2017 were reviewed. Demographics, mechanism of injury, fracture type, neurological level of injury, time to surgery, surgical management, neurological status (AIS), spinal cord independence measure (SCIMIII) scale at admission and discharge, and hospital length of stay. In September 2019 the summative data was analyzed using NDI, VAS, SV-QLI/SCI and length of survival were analyzed for statistical significance. Pathological fractures and dementia were excluded. Results 1613 patients with traumatic SCI were admitted in this period of whom 37 (12 AS and 25 DISH) met the inclusion criteria (mean age 65 years AS; 67 DISH). Fracture-dislocation was the most frequent fracture type (33% AS patients, 24% DISH patients). C4 was the most common neurological level of injury. SCIMIII score at admission was 1 point and 59 at discharge. AIS at admission was A (50%). At time of discharge no patient had neurologically deteriorated. Post-discharge mortality was 58% in AS patients and 32% in DISH patients (p=0.13).ConclusionsBoth AS and DISH patients have high levels of disability and mortality associated with trauma to the cervical spine...

Introducción Los pacientes afectados de espondiloartropatías son susceptibles de fracturas cervicales ante un traumatismo de baja energía, siendo la lesión medular una posible complicación devastadora. El objetivo del presente estudio es describir y evaluar la evolución de la lesión medular de estos pacientes con un seguimiento medio de 7 años. Material y métodos Estudio analítico longitudinal de cohortes prospectivo de pacientes afectados de espondiloartropatías ingresados en nuestro centro en el periodo del 2009 al 2017. Criterios de inclusión: diagnóstico de espondilitis anquilosante (EA) o hiperostosis idiopática difusa (DISH), fractura cervical, presencia de lesión medular. Ingreso en nuestro centro en el postoperatorio inmediato y edad superior al diagnóstico de 18 años. La presencia de demencia o fractura patológica se catalogaron como criterios de exclusión. Se han evaluado las variables de interés: edad, sexo, número de pacientes afectados de EA, DISH, mecanismo energético, tipo de fractura, tiempo hasta la cirugía, tipo de cirugía realizada, SCIM III ingreso/alta, nivel de lesión cervical, ASIA ingreso/alta, tiempo estancia, seguimiento en años. En septiembre del 2019 fueron nuevamente evaluados en consultas externas mediante: cuestionario de discapacidad cervical (NDI), escala visual analógica numérica, cuestionario de calidad de vida validado en castellano para lesionados medulares (QLI) y análisis de la supervivencia. Resultados Mil seiscientos trece pacientes afectados de lesión medular ingresaron en nuestro centro en el periodo de estudio, de los cuales 37 pacientes (12 EA y 25 DISH) cumplían los criterios de inclusión con una edad media de 65 años (EA) y de 67 años (DISH). La fractura luxación fue el tipo de fractura más prevalente (33% EA, 24% DISH). El nivel neurológico de lesión más prevalente tras la fractura cervical fue C4. El SCIM III al ingreso fue de 1 punto y de 59 puntos al alta. La escala ASIA al ingreso fue ASIA... (AU)

Demographics, mechanism of injury, fracture type, neurological level of injury, time to surgery, surgical management, neurological status (AIS), spinal cord independence measure (SCIMIII) scale at admission and discharge, and hospital length of stay.

RESULTS: 1613 patients with traumatic SCI were admitted in this period of whom 37 (12 AS and 25 DISH) met the inclusion criteria (mean age 65 years AS; 67 DISH).

Post-discharge mortality was 58% in AS patients and 32% in DISH patients (p=0.13). CONCLUSIONS: Both AS and DISH patients have high levels of disability and mortality associated with trauma to the cervical spine. Despite their distinct clinical differences, in this cohort there were no statistically significant differences between AS and DISH patients regarding fracture type, SCIMIII, AIS, hospital stay, mortality, VAS, and SV-QLI/SCI after cervical fracture over 7 years follow-up.

La camptocormia y el sídrome de Pisa (pleurothotonus) se caracteriza por una postura anormal en el tronco, con una flexión de la columna toracolumbar de entre 15-45° durante la bipedestación y la marcha que se corrige completamente con el decúbito supino. Se asocia a la enfermedad de Parkinson y a otras enfermedades neurodegenerativas, siendo su fisiopatología incierta. Se presentan 3 casos de camptocormia secundaria a antipsicóticos atípicos (AU)

Camptocormia is an involuntary flexion between 15-45° of the thoracolumbar spine when standing, walking or sitting, which disappears completely in the supine position. Is associated to Parkinson's disease and other neurodegenerative conditions, being its physiopatology unknown. We report three cases of atypical anti-psychotic induced camptocormia (AU)
