ABSTRACT

Resumen: Objetivo: Describir el efecto de la prótesis impresa en 3D Cyborg Beast en la funcionalidad de miembros superiores (MMSS) en adolescentes con amputación congénita parcial de mano. Casos Clínicos: Se seleccionaron 5 pacientes entre 12 y 17 años con amputación congénita parcial de mano en el Instituto Teletón Santiago. Los pacientes fueron entrenados en el uso de la prótesis por 4 sesiones. Se evaluó la función basal (sin prótesis), al mes y los 4 meses de uso de la prótesis con la pauta Bilan 400 points modificada y la percepción de funcionalidad de MMSS sin y con prótesis con la "Upper Extremity Function Index (UEFI)". Al mes y 4 meses de uso, el porcentaje de cambio para funcionalidad de mano fue de -11% y -4% para la extremidad no afectada y de -9% y -2% para la afectada. El porcentaje de cambio para la percepción de funcionalidad de MMSS fue de -62%. Conclusiones: El uso de la prótesis de mano Cyborg Beast no fue una solución funcional para los 5 pacientes incluidos en este estudio. Futuras investigaciones son necesarias para poder mejorar la funcionalidad de estos diseños de prótesis impresa en tecnología 3D.


Abstract: Objective: To describe the effect of the 3D-printed Cyborg Beast prosthesis on upper limbs function in adolescents with congenital hand amputation. Clinical Cases: Five patients aged between 12 and 17 years, with congenital hand amputation were selected. All patients were from the Teletón Institute in Santiago, Chile. The patients were trained for prosthesis use in four sessions. Hand function was evaluated without prosthesis, at 1 and 4 months of use with the modified Bilan 400 points scale, and upper limb function perception was evaluated with the 'Upper Extremity Functional Index (UEFI)'. At 1 month and 4 months of use, the percentage change for hand functionality for the unaffected limbs was between -11% and -4%; and -9% and -2% for the affected limb. The percentage change for the upper limbs perceived function was -62%. Conclusions: The use of the 3D-printed Cyborg Beast prosthesis was not a functional solution for the 5 patients included in this study. Future research is needed to improve the functionality of these types of 3D-printed hand prostheses.

ABSTRACT

Camptodactilia é uma deformidade congênita caracterizada por uma postura em flexão na IFP, geralmente encontrada no dedo mínimo. Afeta aproximadamente 1% da população. A causa primária para esta deformidade é ainda motivo de discussão, não havendo consenso na literatura mundial. Se não for tratada haverá uma piora progressiva em cerca de 80% dos casos. Essa patologia, de aparência relativamente simples, não é fácil de ser tratada. O problema reside no fato da existência de várias formas de apresentação clínica, o que faz com que não haja um modelo único de tratamento efetivo. O objetivo deste estudo é avaliar, retrospectivamente, os resultados dos casos tratados no serviço de Cirurgia da Mão do INTO-MS-RJ, a partir de um protocolo pré estabelecido; e realizar uma análise crítica dos resultados alcançados, separando os casos em seus respectivos subgrupos. Foram avaliados 22 pacientes, num total de 39 dígitos, de janeiro de 2004 a dezembro de 2012. Relacionamos as estruturas anatômicas alteradas encontradas nos casos que foram submetidos a procedimento cirúrgico e seus resultados, tanto no tratamento conservador, como para os cirúrgicos, enfatizando suas principais indicações. Os resultados foram analisados pelo método de Sierget e col da clínica Mayo. Observamos que os casos de camptodactilia isolada do dedo mínimo na forma flexível, >60º, que foram submetidos a tratamento cirúrgico, de maneira uniforme apresentaram resultados excelentes. Nas formas rígidas, nossas observações indicam benefícios com ganho de extensão e correção da deformidade, entretanto o arco de movimento com flexão ativa na IFP é sempre parcial. Com o tempo de evolução alguns casos apresentaram alguma perda de ganho previamente alcançado, o que corrobora a permanente vigilância necessária no acompanhamento, com uso sistemático de órteses, até a fase final do crescimento esquelético.

ABSTRACT

Pollicization substitutes a functioning finger for a deficient thumb. The most indication is thumb hypoplasia with absence or instability of the carpometacarpal joint. However, there are additional causes that may negate thumb function, such as trauma, macrodactyly, multi-fingered hand, and a mirror hand. The technique of pollicization represents a consolidation of contributions from surgeons over the last 100 years. A meticulous stepwise approach from incision to closure is necessary to optimize outcome. Following pollicization, cortical plasticity and motor relearning play a pivotal role in function following pollicization with connections and adjacent sprouting from nearby cortical and/or subcortical territories. Occupational therapy is necessary to encourage large object acquisition followed by smaller objects and ultimately fine pinch. Pollicization is more reliable in patients with isolated thumb hypoplasia and a mobile index finger with robust extrinsic and intrinsic muscle-tendon units compared to and patients with radial forearm deficiencies and diminished index mobility.

ABSTRACT

The records of 27 patients with Radial club hand deformity attending the Hospital and Rehabilitation Centre for Disabled Children (HRDC) were reviewed. This longitudinal intercalary deficiency of forearm growth has a varied clinical presentation and the goals of management are both improved function and cosmesis. We present the results of our treatment and review the current world literature on this challenging orthopaedic deformity.
