Traumatic Isolated Thumb Carpometacarpal Joint Dislocation - Report of Two Clinical Cases / Luxação traumática isolada da articulação trapéziometacárpica - Relato de dois casos clínicos

Abstract Isolated thumb carpometacarpal joint dislocation is a rare lesion that accounts for less than 1% of all hand lesions. The authors present two cases of traumatic isolated thumb carpometacarpal joint dislocation. One of them was treated with closed reduction and cast immobilization, and the other was treated with closed reduction, Kirschner-wires pinning, and cast immobilization. The first patient had a good functional outcome and showed no signs of thumb carpometacarpal instability. The patient treated with Kirschner wires presented signs of clinical instability and radiological subluxation. Isolated thumb carpometacarpal dislocation is a rare lesion that can cause joint instability, which interferes with the normal function of the hand and can lead to articular degenerative changes. The best management of this lesion is still controversial, since there is lack of evidence in the literature showing superiority of one treatment over the other.

Resumo A luxação traumática isolada da articulação trapézio-metacárpica é uma lesão rara que faz parte de menos de 1% de todas as lesões de mãos. Os autores apresentam dois casos de luxação traumática isolada da articulação trapézio-metacárpica. Um dos casos foi tratado com redução fechada e imobilização com gesso, e o outro foi tratado com redução fechada, fixação com fios Kirschner, e imobilização com gesso. O primeiro paciente teve um bom resultado funcional e não mostrou sinais de instabilidade trapeziometacarpal. O paciente tratado com fios Kirschner apresentou sinais de instabilidade clínica e subluxação radiológica. A luxação isolada da articulação trapeziometacarpal é uma lesão rara que pode causar instabilidade articular que interfere com a funcionalidade normal da mão e pode resultar em mudanças articulares degenerativas. O melhor manejo dessa lesão ainda é controverso, já que ainda faltam evidências na literatura que mostrem a superioridade de um tratamento em relação ao outro.

Colgajo en cometa como tratamiento de secuelas de quemadura en pulgar / Kite flap for correction of thumb deformities after burn

Introducción. Múltiples técnicas han sido descriptas para la reconstitutición de la función del pulgar quemado, aunque sin relación costo-beneficio. El colgajo en cometa, descripto por Foucher en 1979, aporta cobertura cutánea, sensibilidad y permite mejoría funcional. El objetivo de este trabajo es presentar nuestra experiencia y resultados utilizando el kite flap. Materiales y métodos. Se realiza un estudio restrospectivo, descriptivo, de 4 casos de secuelas de quemaduras en pulgar de la mano atendidas en el Servicio de Cirugía Plástica y Reparadora del Hospital de Quemados de la Ciudad de Buenos Aires en un periodo comprendido desde el año 2016 al 2019. Se realizan colgajos en cometa en isla o tunelizados y posterior rehabilitación kinésica. El seguimiento mínimo de la serie es de 3 meses y se toman registros fotográficos pre-, intra- y posoperatorios. Las variables analizadas incluyen: sufrimiento de colgajos, dehiscencia, congestión venosa, prendimiento de injertos en zona dadora, reintervenciones y mejoría en la función de abducción del pulgar y pinza de la mano. Resultados. Se realizaron 3 colgajos en cometa tunelizados y 1 en isla. La totalidad se presentaron vitales aunque con congestión venosa en las primeras 72 hs. No se registraron complicaciones y no fueron necesarias reintervenciones. La mejoría en la función de pinza y de abducción del pulgar fue objetivable mediante la observación y referida por los pacientes y/o familiares según correspondiera. Conclusiones. Creemos que el colgajo en cometa es la mejor opción de tratamiento para las secuelas de quemadura en pulgar por aportar adecuada cobertura cutánea, ser técnicamente sencillo y poder hallar el pedículo en el 100% de la población. La congestión venosa es la regla, aunque también la supervivencia, siendo la morbilidad de la zona dadora mínima y la mejoría en la función de pinza y abducción del pulgar francamente objetivable.

Introduction. Multiple techniques have been described for repair the burned thumb function, although without cost-benefit ratio. The kite flap described by Foucher in 1979, provides skin coverage, sensitivity and allows functional improvement. The goal of this study it to present our experience and results obtained using the kite flap Materials and methods. A retrospective, descriptive study of 4 cases of burned hand's thumb treated in the Plastic Surgery Unit of the Hospital de Quemados on Buenos Aires in a three year's period from 2016 to 2019. Island or tunneled's kite flaps and subsequent kinesic rehabilitation are performed. The minimum follow-up of the series is 3 months and fotographic records pre, intra and postoperative are taken. The variables analyzed include: suffering from flaps, dehiscence, venous congestion, grafting losts on the donor zone, reinterventions and improvement in the function of thumb abduction and hand clamp . Results. 3 tunelled kite flaps and 1 on island were made. All of them were vital, although with venous congestion in the first 72 hours. No complications were recorded and no reinterventions were necessary. The improvement in hand clamp function and thumb abduction was marked through observation and when it posible, referred by patients. Conclusions. We believe that kite flap is the best option of treatment for sequelae of burns affecting hand's thumb for providing adequate skin coverage, being technically simple and being able to find the pedicle at 100% of the population. Venous congestion is the rule, although survival is also. Donor zone´s morbidity is minimal and the improvement in thumb function is clear

Colgajo dorsolateral versus colgajo en isla mediopalmar radial para el tratamiento de lesiones traumáticas distales del pulgar. Evaluación clínica / Dorsolateral flap vs. radial midpalmar island flap in the treatment of traumatic distal thumb injuries. Clinical evaluation

Objetivo: Evaluar clínicamente a pacientes con lesiones distales combinadas del pulgar tratados mediante colgajo dorsolateral o colgajo en isla mediopalmar radial. Materiales y Métodos: Se comparó retrospectivamente a 20 pacientes (14 hombres y 6 mujeres; promedio de edad 35 años) con lesiones traumáticas combinadas distales del pulgar, operados por dos cirujanos, con técnicas diferentes. Los pacientes no tenían antecedentes quirúrgicos y el seguimiento mínimo fue de 24 meses. Se evaluaron el resultado subjetivo usando el índice de satisfacción, la escala analógica visual para dolor y el puntaje QuickDASH, y el resultado objetivo mediante el test de discriminación de 2 puntos, el tiempo quirúrgico promedio y la necesidad de reeducación espacial digital. Resultados: La media desde el ingreso hasta el alta laboral fue de 7 semanas (rango 6-8). Resultados promedio posoperatorios: escala analógica visual 01/10, ambos grupos. Grupo con colgajo dorsolateral: índice de satisfacción 97%, test de discriminación de 2 puntos 4 mm, puntaje QuickDASH 2,5; tiempo quirúrgico 45 min, sin necesidad de reeducación espacial digital. Grupo con colgajo en isla mediopalmar radial: índice de satisfacción 92%, test de discriminación de 2 puntos 6 mm, puntaje QuickDASH 8, tiempo quirúrgico 60 min; 4 pacientes requirieron reeducación espacial digital. Conclusión: Los colgajos dorsolateral y en isla mediopalmar radial resultaron eficaces en el tratamiento de lesiones traumáticas distales del pulgar, aunque el colgajo dorsolateral tuvo mejores puntajes de evaluación objetiva y requirió menos tiempo quirúrgico. Nivel de Evidencia: III

Objective: To clinically evaluate patients with combined distal thumb lesions treated by a dorsolateral flap or radial midpalmar island flap. Materials and Methods: We retrospectively compared 20 patients (14 males and 6 females, averaging 35 years) with combined distal thumb traumatic lesions, who were operated on by two surgeons using different techniques. Patients had no previous surgical history and a minimum follow-up period of 24 months. Subjective outcome was evaluated by satisfaction index (SI), visual analogue scale (VAS), and QuickDASH score. Objective outcome was evaluated by two-point discrimination test (TPDT), average surgical time (ST), and need for digital spatial reeducation (DSR). Results: Time from admission to medical discharge averaged 7 weeks (range, 6-8). Average postoperative results: VAS for pain, 01/10 (both groups); IS, 97% vs. 92% (dorsolateral flap group vs. radial midpalmar island flap); TPDT, 4 mm vs. 6 mm; QuickDASH, 2.5 vs. 8; ST, 45 minutes vs. 60 minutes; need for DSR, 0 vs. 4 cases. Conclusion: Both the dorsolateral flap and the radial midpalmar island flap techniques were effective in the treatment of distal thumb traumatic lesions, although the dorsolateral flap achieved better objective evaluation scores and required less ST.

Colocación de un tornillo transfisario medial en la cadera espástica de niños con parálisis cerebral. Eficacia y seguridad / Medial transphyseal screw placement for spastic hip treatment in children with cerebral palsy. Effectiveness and safety

Introducción: En estudios experimentales y clínicos, los resultados con el tornillo excéntrico transfisario medial para producir varo fueron alentadores. El propósito de este estudio fue determinar si colocar un tornillo en el fémur proximal es un gesto eficaz y seguro en caderas espásticas de niños con parálisis cerebral. Materiales y Métodos: Se incluyó a pacientes con parálisis cerebral infantil y caderas en riesgo. Se compararon la serie A: pacientes con liberación de partes blandas más colocación de un tornillo excéntrico transfisario medial en el fémur proximal y la serie B: pacientes solo con liberación de partes blandas. Se determinaron el test de Rang, el índice de migración de Reimer, el ángulo cervicodiafisario y las complicaciones, antes de la cirugía y después. Resultados: Se operó a 18 pacientes (36 caderas): 10 de la serie A y 8 de la serie B, con una mediana de edad de 51 meses y una mediana de seguimiento, de 3 años. Al comparar por delta de medianas todas las variables preoperatorias y posoperatorias, hubo una diferencia estadísticamente significativa solo en el delta de mediana del ángulo cervicodiafisario de las caderas izquierdas (-5 vs. 0, p 0,02). Conclusiones: La liberación de partes blandas es eficaz para prevenir la luxación de la cadera espástica. La colocación de un tornillo transfisario excéntrico en la cadera espástica no produjo cambios y no fue inocua. La hemifisiodesis medial de la cadera es una atractiva solución teórica para tratar los problemas ocasionados por el valgo excesivo, pero se requieren más estudios. Nivel de Evidencia: III

Introduction: Animal and clinical studies have shown promising results for the varus-producing placement of a medial eccentric transphyseal screw. The purpose of this study was to establish if the placement of a screw in the proximal femur is an effective and safe approach for spastic hips in children with cerebral palsy (CP). Materials and Methods: We compared two series of pediatric CP patients (Gross Motor Function Classification System [GMFCS] III, IV and V) with "hips at risk." Series A patients were treated with soft-tissue release plus a medial eccentric transphyseal screw in the proximal femur. Series B patients were only treated with soft-tissue release. Patients were evaluated pre and postoperatively to determine their Rang test score, Reimer's migration index (MI), diaphyseal cervical angle, and complications. Results: From a total of 18 patients operated, 36 hips, 55% (10) belonged to the A Series and 45% (8) to the B Series. The median age was 51 months (IQR, 41-108). The median follow-up was 3 years (IQR, 2.4-5.8). The comparative analysis of all preoperative and postoperative variables yield only one statistically significant difference: the median left hip diaphyseal cervical angle (-5 vs. 0, P 0.02). Conclusions: The release of soft tissues was effective to prevent the spastic hip dislocation. The placement of medial eccentric transphyseal screw in spastic hips produced some complications and no beneficial changes. Medial hemiphysiodesis of the hip remains nothing but an attractive theoretical solution for the treatment of problems caused by excessive valgus. However, further studies are warranted. Level of Evidence: III

Toe thumb: A musculoskeletal disorder related to transesophageal echocardiography.

The musculoskeletal disorders (MSD) are common in healthcare providers and those who are doing sonography are also affected. There are reports of MSD in healthcare providers who do transthoracic echocardiography. Transesophageal echocardiography (TEE) is being regularly used in peri‑operative setting. We describe MSD of hand in a cardiovascular and thoracic anesthesiologist who has been performing TEE scanning for 10% of his work‑time in operating room and critical care area for the last 8 years. As the role of TEE is increasing and many doctors are doing it on a routine basis, the knowledge of association of MSD with TEE and measures to prevent it is important.

Bilateral Carpometacarpal Joint Dislocations of the Thumb

A traumatic carpometacarpal joint dislocation of the thumb accounts for less than 1% of all hand injuries. Optimal treatment strategies for this injury are still a subject of debate. In this article, we report a case of bilateral thumb carpometacarpal joint dislocations: a unique combination of injuries. We believe our case is the second report of bilateral carpometacarpal joint dislocation regarding the thumb in English literature. It was successfully treated with closed reduction and percutaneous K-wires fixation on one side, and an open reduction and reconstruction of the ligament on the other side.

Accidental digital injection of adrenaline from an auto-injector device

A 29 year old female colleague presented to the Emergency Department, of Hamad General Hospital, with an accidental injection of adrenaline into her right thumb from an auto-injector device. She received the injury whilst she was teaching her mother, an acute allergy sufferer, how to use the auto-injector. On arrival at the emergency department, her right thumb was pale, edematous and cold, so she was immediately given a local infiltration of 0.5% phentolamine mesylate [injected at the puncture site], a digital block with lidocine 1% and the thumb was wrapped with a trans-dermal nitroglycerin patch. One hour later the right thumb became pinkish, warm and the edema subsided. The patient was discharged home with outpatient follow-up

distally based radial forearm flap in reconstruction of complex defects of the hand

The hand is exposed to various types of trauma, the majority of which involve multiple tissues which needs to be repaired in the most perfect way. The distally based radial forearm flap is one of the commonly used flaps for reconstruction of hand defects. The aim is to test the applicability and the versatility of the distally based radial forearm flap in complex soft tissue reconstruction of the hand. Nine patients were treated using distally-based radial forearm flaps. There were seven males and two females, mean age was 21 year. Reconstructed sites involved the thumb, the first web, the palm and dorsum of the hand. Neurofasciocutaneous flap was transferred in one case, adipofascial flap in one case, all the remaining flaps were fasciocutaneous island flaps. All the flaps survived completely. There were two donor sites complications, but no major functional disturbances. No patient had symptoms of cold intolerance or other ischemic changes. Distally based radial forearm flap is very useful in hand reconstruction especially when no suitable local flaps can solve the problem and it can permit further surgical procedures to be done underneath when indicated

Tratamiento de la hipoplasia severa del pulgar con modificación de la técnica de Buck-Gramcko / Treatment of severe hipoplasia of the thumb with modified Buck-Gramcko procedure

La pulgarización del dedo índice mediante la técnica de Buck-Gramcko constituye el tratamiento clásico para la hipoplasia severa y la aplasia del pulgar. En este trabajo se evaluó la eficacia de una modificación aplicada a esta técnica. Se realizó un estudio preliminar en 8 pacientes con diagnóstico de hipoplasia o aplasia del dedo pulgar, atendidos en el Hospital Frank País, en el periodo comprendido entre el 1ro de enero de 2004 hasta el 28 de febrero de 2006. Se realizaron 9 intervenciones quirúrgicas. La posición promedio de abducción palmar fue de 42,22. La posición de reposo promedio en pronación fue de 118,33º. El arco promedio de movimiento en abducción palmar fue de 58,33. El arco de movimiento promedio de pronación logrado por los pacientes fue de 123,33. En 8 (88,9 por ciento) de las 9 manos operadas se logró una oposición del nuevo pulgar con respecto a los demás dedos. En ningún paciente fue necesario realizar una oponoplastia secundaria. En 4 manos el resultado fue excelente, en otras 4 fue bueno y en una fue regular. Esta modificación proporcionó en la mayoría de los pacientes una buena posición del dedo pulgarizado y disminuyó la probabilidad de necesitar una segunda intervención quirúrgica para lograr un resultado satisfactorio.

Pollicization of the index thumb through Buck-Gramcko technique is the classical treatment for aplasia and severe hipoplasia of the thumb. This paper evaluated the efficacy of a modification introduced to Buck-Gramcko procedure. A preliminary study was conducted in 8 patients diagnosed with hipoplasia or aplasia of the thumb and seen at Frank Pais orthopedic hospital from January 1st, 2004 to February 28th 2006. Nine surgeries were performed. The average position of palmar abduction was 42,22. The average rest position in pronation was 118,33. The average movement arc in palmar abduction was 58,33. The average movement arc in pronation reached in patients was 123,33. Eight (88,9por ciento) out of the 9 operated hands succeeded in opposing the new thumb to the rest of the fingers. No patient required a secondary oponoplasty. The outcome was excellent in 4 hands, good in 4 hands and regular in one hand. The introduced modification provided the majority of patients with a good position of the pollicized finger and opposition movement with respect to the rest of the fingers, all of which reduced the possibilities of a second surgery to attain a satisfactory result.

Dans le présent travail, l'efficacité de cette technique est évaluée. Une étude préliminaire de 8 patients diagnostiqués et traités pour hypoplasie ou aplasie du pouce à l'hôpital ½ Frank Pais ¼ du 1 janvier 2004 au 28 février 2006, a été réalisée. Neuf opérations chirurgicales ont été réalisées. L'abduction palmaire a été de 42.22 en moyenne. La pronation en repos a été de 118.33º en moyenne. La courbe de mouvement en abduction palmaire a été de 58.33 en moyenne. La courbe de mouvement en pronation atteinte par les patients a été de 123.33 en moyenne. Sur 9 mains opérées, 8 (88.9) ont réussi l'opposition du nouveau pouce. Aucun patient n'a eu besoin d'une deuxième opération. Les résultats ont été excellents en 4 mains, bons en 4, et passables en une seule main. La modification de la technique a permis une bonne position et un bon mouvement d'opposition du doigt transplanté, réduisant ainsi le besoin d'une deuxième opération chirurgicale.

Reconstruccion del pulgar con tecnica de Morrison / Thumb reconstruction with Morrison technique

Introduccion: En 1980, Morrison informo buenos resultados en la reconstruccion del pulgar amputado con el uso de un colgajo neurovascular envoltorio tomado del hallux, recreando un neopulgar muy similar al contralateral y con minimas secuelas en la zona dadora. El presente trabajo es una evaluacion retrospectiva de nuestra experiencia en la reconstruccion del pulgar amputado en 13 casos con un colgajo microquirurgico de envoltura tomado del hallux. Materiales y metodos: El primer paso es la diseccion del muñon de amputacion en la mano. El segundo paso es la elevacion del colgajo. El hallux se “desviste” incluyendo el complejo ungular y los dos tercios distales de la segunda falange. El tercer paso es la insercion del injerto tomado de cresta iliaca. En el cuarto paso el colgajo “viste” al injerto oseo, se realiza la osteosintesis, se anastomosan los colaterales nerviosos y se efectuan las anastomosis vasculares en la tabaquera anatomica. El ultimo paso es el cierre del sitio donante. Entre noviembre de 2000 y enero de 2006 hemos realizado la tecnica de Morrison para reconstruccion del pulgar en 13 oportunidades en 12 pacientes. La edad promedio fue de 27,6 años. Se incluyo en este estudio a los pacientes con amputaciones del pulgar alrededor de la articulacion metacarpofalangica que presentaron una musculatura de la eminencia tenar activa y con articulacion trapeciometacarpiana movil e indolora. En tres casos debimos realizar tecnicas de cobertura previa a nivel del muñon: dos casos con colgajos locales y un caso con cobertura por un colgajo antebraquial en isla. Resultados: Todos los casos fueron exitosos desde el punto de vista vascular. En un paciente se produjo la fractura del injerto oseo al año de la cirugia. Fuerza muscular: fuerza de puño un 92 por ciento en promedio y un 65 por ciento en promedio en la fuerza de pinza. Estado sensorial: los pacientes tuvieron un promedio de 11 mm de discriminación de 2 puntos. Uso de la mano: se realizo un cuestionar...

[Benefit of lselin's technique in the treatment of fractures of the base of the first metacarpal joint [Report of 15 cases]]

Bennett's fractures are always serious injuries to the hand. The authors have reviewed 15 cases treated by Iselin's pinning technique with a mean range follow-up of 06 years. 13 were good or satisfactory results according to Vardon's Seale. The Iselin's technique is recommended as the routine technique for Bennett's fractures
