Resumen

Las prótesis de húmero impresas en 3D ofrecen una solución para pacientes de edad avanzada con pérdida de hueso y no unión. Este implante específico para el paciente proporciona una fijación estable y mejora la función de las extremidades, reduciendo la morbilidad del sitio donante asociada con los injertos óseos tradicionales.

Área de la Ciencia:

La cirugía ortopédica es una cirugía ortopédica.
Ingeniería biomédica de la ingeniería biomédica.
La medicina regenerativa es una medicina regenerativa.

Sus antecedentes:

La no unión del eje humeral con la pérdida ósea segmentaria presenta un desafío significativo, particularmente en pacientes de edad avanzada.
Los métodos tradicionales de reconstrucción como los injertos fibulares implican una considerable morbilidad en el sitio del donante.
Los avances en la tecnología de impresión 3D presentan soluciones innovadoras específicas para el paciente.

Objetivo del estudio:

Evaluar la eficacia de una prótesis de húmero intercalar personalizada impresa en 3D para el tratamiento de la no unión del eje humeral con pérdida ósea extensa.
Evaluar la viabilidad de este enfoque en un paciente anciano con un defecto óseo segmental significativo.

Principales métodos:

Una paciente de 70 años con una historia de 6 años de no unión del eje humeral y pérdida ósea de 13,68 cm se sometió a reconstrucción.
Se diseñó una prótesis humeral intercalar específica para el paciente utilizando impresión 3D, incorporando una celosía porosa para la osteointegración.
La prótesis fue asegurada con una placa de titanio personalizada y tornillos de bloqueo.

Principales resultados:

La reconstrucción logró una fijación estable y restauró la alineación humeral.
El paciente experimentó una mejor estabilidad de las extremidades y una recuperación funcional, lo que permitió una movilización temprana.
La prótesis personalizada impresa en 3D demostró una osteointegración y estabilidad exitosas.

Conclusiones:

Las prótesis de húmero intercalar personalizadas impresas en 3D son una alternativa viable al injerto óseo convencional para casos específicos de no unión humeral con grandes defectos óseos segmentarios.
Esta tecnología ofrece una fijación estable, promueve la recuperación funcional temprana y minimiza la morbilidad del sitio donante.
Los implantes impresos en 3D específicos para el paciente representan un avance prometedor en la reconstrucción ortopédica.

Bones of the Upper Limb: Humerus

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Line Loss

Line Loss

The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Reducing Line Loss

Reducing Line Loss

In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

Data Reporting and Recording

Data Reporting and Recording

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Major Losses in Pipes

Major Losses in Pipes

When a fluid flows through a pipe, it experiences energy losses due to frictional resistance along the pipe walls, known as major losses. These energy losses result in a pressure drop, which varies based on the flow conditions — whether laminar or turbulent — and the specific physical properties of the fluid and pipe.
Fluid flow can be classified as laminar or turbulent, primarily based on the Reynolds number. This dimensionless number reflects the relative influence of inertial to viscous...

Minor Losses in Pipes

Minor Losses in Pipes

In pipe systems, minor losses refer to energy losses arising from components such as valves, bends, fittings, expansions, and other features that disrupt the steady flow of fluid. These disturbances cause energy dissipation through turbulence and resistance, which engineers quantify to manage system efficiency effectively.
Valves play a significant role in generating minor losses by obstructing or redirecting the fluid flow. When a valve is closed or partially closed, it restricts the flow...
