Utilidad del sistema Myo Plus en pacientes amputados transradiales / Use of the Myo Plus system in transradial amputation patients

Las amputaciones de miembro superior son infrecuentes pero provocan una gran discapacidad. Suelen ser de etiología traumática y en varones jóvenes menores de 40 años y activos. La frecuencia de la amputación de nivel transradial es del 35% de los casos, siendo la prótesis mioeléctrica la que aporta mayor funcionalidad. Un 25% de los pacientes abandona el uso de la prótesis, siendo la complejidad de su uso, mediante 2 electrodos convencionales, una de las causas más frecuentes del abandono. El sistema Myo Plus, con 8 canales de electromiografía, facilita al paciente el control protésico utilizando el miembro fantasma y consiguiendo los patrones de cierre, apertura y pronosupinación de la mano en un tiempo menor al convencional y más fácilmente. Además, conlleva un menor tiempo de rehabilitación, disminuyendo los costes y los desplazamientos innecesarios, sin incrementar el tiempo de fabricación del encaje (AU)

Upper limb amputations are uncommon but cause severe disability. It is usually of traumatic origin and in young males less than 40 years-old, and active. The frequency of amputation at transradial level is around 35% of cases, with the myoelectric prosthesis achieving greater functionality. Around 25% of the patients give up using of the prosthesis, due to its complexity of use by means of 2 conventional electrodes, one of the most common causes for giving up. The Myo Plus system with an 8-channel electromyograph helps the patient to control the prosthesis using the phantom limb and achieving the closing, opening, and pronation-supination patterns of the hand in a time less than the conventional one and more easily. It also leads to less rehabilitation time, decreasing costs and unnecessary travel, without increasing the time for the manufacture of the socket (AU)

Paciente con amputación transfemoral derecha, clavo gamma y síndrome hemimotor derecho: valoración y manejo del proceso de protetización / Patient with a right transfemoral amputation, gamma nail, and right Hemi-motor syndrome: assessment and management of the prosthetic fitting

Introducción: la decisión de protetizar a un paciente amputado depende de: la etiología, nivel de amputación, uni o bilateralidad, comorbilidades, soporte sociofamiliar, capacidad funcional y motivación del paciente. Observación clínica: varón, 83 años, diabético, cardiopatía isquémica, accidente cerebrovascular con paresia braquial derecha residual en año 2000. Clavo gamma por fractura pertro-cantérea derecha en 2012 y amputación transfemoral derecha en 2018 de causa vascular. Se protetiza mediante encaje de contención isquiática CAT-CAM, sistema de suspensión tipo Kiss, rodilla de bloqueo a la extensión con adaptación del sistema de desbloqueo en porción antero-interna del encaje y pie Sach. Tras tratamiento fisioterápico, consigue deambulación autónoma con ayuda de un bastón y tercera persona por dificultad para agarre de MSD. Conclusión: los médicos rehabilitadores debemos apostar por dotar a nuestros pacientes de autonomía y funcionalidad, siempre que sea viable.

Introduction: prosthesis, an amputee patient, depends on etiology, level, uni or bilaterality, comorbidities, socio-family support, functional capacity, and motivation of the patient. Clinical observation: male, 83 years old, diabetic, ischemic heart disease, stroke with residual upper right limb (URL) paresis in 2000. Gamma nail due to the right trochanteric fracture in 2012, and right transfemoral amputation in 2018 of vascular cause. Prosthetic fitting CAD-CAM socket/interface, Kiss type suspension system, extension locking knee with an adaptation of the unlocking system in the antero-internal portion of the socket, and Sach foot. After physiotherapeutic treatment, he achieves independent walking with the help of 1 cane and third-person due to difficulty in the URL grip. Conclusion: rehabilitation doctors must bet on providing our patients with independency, and better function, whenever it is viable.

Natural History After Below-knee Amputation: Analysis of Survival and Prosthetic Fitting Over 2 Decades. / Historia natural del paciente sometido a una amputación infracondílea: análisis de la supervivencia y protetización durante 2 décadas.

INTRODUCTION: This study sought to evaluate the natural history of patients undergoing below-knee amputation (BKA) and compare their evolution over 2 decades, as well as survival predictors, prosthetic fitting, and contralateral amputation. METHODS: Retrospective study of 209 consecutive patients (mean age 72.9 years; 68% males) who underwent BKA in 2 periods: 1996-2005 and 2006-2015. The fitting of prostheses, risk of contralateral amputation and survival, as well as their predictive factors, were assessed by survival analysis. RESULTS: 133 BKA were performed from 1996-2005 and 106 from 2006-2015. The etiology that motivated the BKA was acute ischemia (4.3%), chronic ischemia (34.0%), infection (9.1%) or mixed (chronic+infection, 52.6%), with no differences found between periods. Survival: mortality within one month=9.2%, one year=31.9%, 2 years=43.8% and 5 years=63.9%, with no significant differences between the 2 periods. Prosthetic: the fitting rate was 44.5% throughout the follow-up, with no significant differences between the two periods. 41.1% patients managed to walk. Contralateral amputation: 20.1% of the patients later required a major contralateral amputation, with no significant differences between the two periods. CONCLUSIONS: In the last decade, fewer BKA have been performed probably, due to higher previous interventional revascularization. Despite this, the results of fitting, contralateral amputation or survival were not modified. In any case, the number of patients who are able to achieve ambulation is modest, so it emphasizes the need for an optimal selection of patients with BKA with the goal of prosthetic fitting.
