Tratamiento del pie zambo congénito a lo largo de la historia / Congenital clubfoot treatment throughout history

El tratamiento del pie zambo congénito ha evolucionado a lo largo de la historia. Desde la Antigüedad hasta finales de la Edad Media se utilizaron las manipulaciones e inmovilizaciones seriadas. Del Renacimiento al siglo XVII se crearon las primeras ortesis. En el siglo XVIII comenzó el uso de moldes de yeso y se desarrollaron ortesis y calzados complejos. El período del siglo XIX hasta la tercera década del XX, se caracterizó por la práctica de las tenotomías, siendo la cirugía el principal enfoque terapéutico. En el siglo XX, Joseph Kite e Ignacio Ponseti describieron su eficaz método no quirúrgico, lo que produjo el regreso a las manipulaciones e inmovilizaciones seriadas frente a la cirugía agresiva. Cuando se revisa la historia del tratamiento del pie zambo, sorprende ver que los médicos tratantes cometían los mismos errores una y otra vez, porque ignoraban constantemente lo que ya habían aprendido de sus antecesores y, en su lugar, a menudo se veían confundidos por las nuevas informaciones o tendencias. En el siglo XXI, los avances en biología celular, genética molecular, diagnóstico por la imagen, biomecánica y biomateriales hacen prever que se puedan diseñar tratamientos personalizados para los pacientes con pie zambo(AU)

Congenital clubfoot treatment has evolved throughout history. Serial manipulations and immobilizations were used from antiquity to the end of the Middle Ages. From the Renaissance to the 17th century the first orthotics were created. In the 18th century, the use of plaster casts began and complex orthotics and footwear developed. The period from 19th century until the third decade of the 20th century was characterized by the practice of tenotomies, with surgery being the main therapeutic approach. In the 20th century, Joseph Kite and Ignacio Ponseti described their effective non-surgical method, which led to the return to serial manipulations and immobilizations in the face of aggressive surgery. When reviewing the history of clubfoot treatment, it is surprising to see that the treating doctors made the same mistakes over and over again because they constantly ignored what they had already learned from their predecessors and, instead, were often confused by the new ones information or trends. In the 21st century, advances in cell biology, molecular genetics, diagnostic imaging, biomechanics and biomaterials suggest that personalized treatments can be designed for patients with clubfoot(AU)

Myelomeningocele sac associated with worse lower-extremity neurological sequelae: evidence for prenatal neural stretch injury?

OBJECTIVE: To determine whether the presence of a myelomeningocele (MMC) sac and sac size correlate with compromised lower-extremity function in fetuses with open spinal dysraphism. METHODS: A radiology database search was performed to identify cases of MMC and myeloschisis (MS) diagnosed prenatally in a single center from 2013 to 2017. All cases were evaluated between 18 and 25 weeks. Ultrasound reports were reviewed for talipes and impaired lower-extremity motion. In MMC cases, sac volume was calculated from ultrasound measurements. Magnetic resonance imaging reports were reviewed for hindbrain herniation. The association of presence of a MMC sac and sac size with talipes and impaired lower-extremity motion was assessed. Post-hoc analysis of data from the multicenter Management of Myelomeningocele Study (MOMS) randomized controlled trial was performed to confirm the study findings. RESULTS: In total, 283 MMC and 121 MS cases were identified. MMC was associated with a lower incidence of hindbrain herniation than was MS (80.9% vs 100%; P < 0.001). Compared with MS cases, MMC cases with hindbrain herniation had a higher rate of talipes (28.4% vs 16.5%, P = 0.02) and of talipes or lower-extremity impairment (34.9% vs 19.0%, P = 0.002). Although there was a higher rate of impaired lower-extremity motion alone in MMC cases with hindbrain herniation than in MS cases, the difference was not statistically significant (6.6% vs 2.5%; P = 0.13). Among MMC cases with hindbrain herniation, mean sac volume was higher in those associated with talipes compared with those without talipes (4.7 ± 4.2 vs 3.0 ± 2.6 mL; P = 0.002). Review of the MOMS data demonstrated similar findings; cases with a sac on baseline imaging had a higher incidence of talipes than did those without a sac (28.2% vs 7.5%; P = 0.007). CONCLUSIONS: In fetuses with open spinal dysraphism, the presence of a MMC sac was associated with fetal talipes, and this effect was correlated with sac size. The presence of a larger sac in fetuses with open spinal dysraphism may result in additional injury through mechanical stretching of the nerves, suggesting another acquired mechanism of injury to the exposed spinal tissue.
