Cirugía de la anquilosis de cadera por osificación heterotópica secundaria a lesión medular / Surgical treatment of hip ankylosis due to heterotopic ossification secondary to spinal cord injury

Objetivo: Exponer nuestra experiencia en el diagnóstico y tratamiento quirúrgico de la anquilosis de cadera secundaria a osificación heterotópica periarticular. Material y métodos: Estudio descriptivo, longitudinal, de cohortes, retrospectivo, de 20 pacientes consecutivos (30 caderas) afectos de osificación heterotópica periarticular secundaria a lesión medular en los últimos 10 años, con un seguimiento mínimo de un año. Se realizó una revisión de las historias clínicas y pruebas de imagen, se valoró el tipo y localización de la osificación heterotópica periarticular, la movilidad pre- y postoperatoria, tipo, nivel y causa de la lesión medular según escala ASIA, tiempo desde la lesión medular hasta la cirugía, existencia de hábito tabáquico, abordaje quirúrgico utilizado y complicaciones asociadas a la cirugía. Resultados: Se evaluaron un total de 20 pacientes (30 caderas): 16 pacientes presentaron un lesión medular completa ASIA A y 4, ASIA B. Todos los pacientes presentaban una anquilosis completa de la cadera que limitaba la sedestación en silla de ruedas, la higiene y los cambios posturales. La movilidad posquirúrgica media fue de 90° de flexión, 20° de rotación interna y 40° de rotación externa. En todos los pacientes se realizó fisioterapia intensiva en la articulación intervenida en el postoperatorio inmediato así como la administración de 200 mg de celecoxib cada 24h durante un mes con el fin de prevenir la recidiva de la osificación. En ningún caso de la serie tuvimos recidivas de la osificación. Conclusiones: El tratamiento quirúrgico mediante exéresis de la osificación hasta conseguir un rango de movilidad adecuado es el tratamiento de elección para los pacientes con anquilosis de cadera

Objectives: To expose our experience in the diagnostic and surgical treatment of neurogenic heterotopic ossification of the hip. Material and methods: We designed an observational retrospective descriptive study including 20 patients (30 hips) with neurogenic heterotopic ossification of the hip secondary to spinal cord injury attended in our institution in the last 10 years, with a minimum of one year follow-up. Medical files and imaging studies were reviewed. The study variables analyzed were: type and localization of neurogenic heterotopic ossification, pre-post excision range of motion, level and aetiology of spinal cord injury, ASIA score, smoking history, surgical approach and complications associated with surgery. Results: A total of 20 patients were treated with resection of heterotopic ossification in 30 hips. 16 patients presented ASIA A spinal cord injury and 4 ASIA B spinal cord injury. Preoperatively all the patients had severe ankylosis in the hip that made sitting in a wheel chair and activities such as repositioning and hygiene difficult. The average postoperative motion at the follow-up evaluation was 90° in flexion, 20° of internal rotation and 40° of external rotation. Immediately after surgery all the patients followed a specific intensive physiotherapy regime for the hip and celecoxib 200 mg was administrated daily orally for a month to prevent recurrence of heterotopic bone formation. None of the patients reviewed suffered a recurrence of heterotopic bone formation. Conclusions: Surgical excision of hip ossification in order to achieve functional ROM of the hip is the best treatment for patients with neurogenic heterotopic ossification of the hip
