Objetivos

Los objetivos de este artículo fueron determinar, mediante la medición de diversos ángulos, la corrección de la hiperlordosis lumbosacra tras un proceso de elongación femoral bilateral según la técnica Icatme, así como la ausencia de síntomas neurológicos derivados de la estenosis del canal tras el alargamiento femoral.

Pacientes y métodos

En este estudio se incluyeron 34 pacientes acondroplásicos, con una edad media actual de 22,3 años, a los cuales se les ha practicado un alargamiento femoral según la técnica Icatme y en los cuales se ha medido, en radiografías de perfil de la columna dorsolumbar preelongación y postelongación, toda una serie de ángulos que se enumeran en el texto.

Resultados

Los resultados obtenidos mostraron una disminución del ángulo de lordosis lumbar, de Sezè y L5-S1, así como un aumento de los ángulos lumbosacro, de Junghans y sacro, que clínicamente se traduce en una corrección de la hiperlordosis lumbar, verticalización del sacro y mejora de la inflexión toracolumbar y lumbosacra, acercándose a los valores promedio estándar para los individuos no acondroplásicos.

Conclusiones

La estática de la columna lumbar del paciente acondroplásico se modifica tras un proceso de elongación femoral bilateral (técnica Icatme), que se acercan a los valores estándar de los individuos sin acondroplasia.

Tras un proceso de alargamiento de fémures según la técnica Icatme se consigue una corrección de la hiperlordosis lumbar con la cual se previene la aparición de sintomatología neurológica derivada de la estenosis del canal.

La incidencia de complicaciones neurológicas derivadas de la estenosis del canal lumbar es baja respecto a los individuos acondroplásicos sin elongación para iguales grupos de edad y sexo.

Objective

To determine through the measurement of different angles the correction of lumbar hyperlordosis after bilateral femoral lengthening using the Icatme technique and to assess the absence of neurological symptomatology secondary to stenosis of the lumbar canal after femoral lengthening.

Patients and methods

Thirty-four patients with achondroplasia were studied. Mean age was 22.3 years. The patients underwent femoral lengthening using the Icatme technique. X-rays of the lateral rachis taken before and after lengthening were used to measure a series of angles.

Results

The lumbar lordosis angle, Sezè's angle and the L5-S1 angle decreased while the lumbosacral angle, Jungham's angle and the sacrum angle increased, leading to correction of lumbar hyperlordosis, verticalization of the sacrum and improvement in thoracolumbar and lumbosacral inflection. Values were similar to the standard for individuals without achondroplasia.

Conclusions

Femoral lengthening using the Icatme technique in achondroplastics modifies the statics of the lumbar spine, making them similar to those of non-achondroplastics. The procedure corrects lumbar hyperlordosis and prevents the appearance of neurological symptomatology due to stenosis of the lumbar canal. The incidence of neurological complications due to stenosis of the lumbar canal in achondroplastics who have undergone femoral lengthening is low compared with that of achondroplastics of the same age and sex who have not undergone this procedure.
