Tumor glómico causante de dolor de dedo crónico: la prueba de detección de isquemia es un signo clínico fiable para su diagnóstico. Informe de un caso y revisión de la literatura / Glomus tumor causing chronic finger pain: Ischemia test is a reliable clinical sign for the diagnosis. Case report and review of literature

Los tumores glómicos (TG) son neoplasias benignas raras, que se derivan de la estructura neuroarterial denominada cuerpo glómico, un shunt arteriovenoso especializado implicado en la regulación de la temperatura. Representan menos de 2% de los tumores del tejido blando, y entre 1 y 4,5% de los tumores de la mano. Aun cuando sus primeras descripciones aparecieron hace casi 100 años, son comunes la demora y la ausencia diagnósticas, las cuales originan un sufrimiento terrible. La tríada diagnóstica clásica consiste en dolor espontáneo, sensación de presión y sensibilidad, e hipersensibilidad al frío. La imagen de resonancia magnética (IRM) sigue siendo la modalidad de imagen más útil. La supresión del dolor tras inflar un esfigmomanómetro por encima de los niveles de la presión arterial sistólica (prueba de detección de isquemia) es altamente diagnóstica, por lo que sugerimos el uso rutinario de esta prueba simple en los casos de dolor en la extremidad superior de etiología desconocida. La resección quirúrgica es el tratamiento de elección, y es curativa. (AU)

Glomus tumors are a rare benign neoplasm arising from the neuroarterial structure called the glomus body, a specialized arteriovenous shunt involved in temperature regulation. They represent less than 2% of soft tissue tumors and between 1 and 4.5% of hand's tumors. Even though its first descriptions appeared almost 100 years ago, late and missed diagnoses are common, which leads to terrible suffering. The classic diagnostic triad consists of spontaneous pain, pressure sensation and tenderness, and cold hypersensitivity. Magnetic resonance imaging stills the most useful imaging modality. Abolition of pain after inflating a blood pressure cuff above systolic blood pressure levels (ischemia test) is highly diagnostic, so we suggest the routine use of this simple test in cases of upper limb pain of unknown etiology clear. Surgical excision is the treatment of choice and is curative. (AU)

Acro-osteólisis, hallazgos de imagen y posibles diagnósticos etiológicos / Acro-osteolysis, imaging findings and possible aetiological diagnoses

La acro-osteólisis es un hallazgo radiológico infrecuente caracterizado por una reabsorción o destrucción ósea que afecta típicamente a las falanges distales de la mano.Sus causas son múltiples. Puede estar asociada a enfermedades sistémicas, tener un origen familiar, ser idiopática o secundaria a agentes externos, por lo que el patrón radiográfico, la edad del paciente y una buena historia clínica serán claves para llegar a su diagnóstico etiológico.Presentamos el caso de una mujer de 40 años que consulta por dolor de aproximadamente 1 año de evolución a nivel de la región interfalángica distal del primer y segundo dedo de la mano derecha. Entre las pruebas complementarias realizadas durante el estudio, destaca la radiografía simple de la mano, donde se observa una reabsorción parcial en banda de la región media de la falange distal del primer y segundo dedo, compatible con acro-osteólisis.(AU)

Acro-osteolysis is a rare radiological finding characterized by bone resorption or destruction that typically affects the distal phalanges of the hand.There are many causes. The condition can be associated with systemic diseases, have a family origin or be idiopathic or secondary to external agents. Therefore, the radiographic pattern, the patient’s age in addition to a good clinical history will be key to diagnosing its aetiology.We report the case of a 40-year-old woman who consulted for pain of approximately one year clinical course at the level of the distal interphalangeal region of the first and second fingers of the right hand. Among the complementary test performed during the study the x-ray revealed a band-like partial resorption in the middle region of the distal phalanx of the first and second fingers, compatible with acro-osteolysis.(AU)

Trigger Finger or De Quervain Tenosynovitis after Surgical Treatment for Carpal Tunnel Syndrome / Dedo em gatilho ou tenossinovite de De Quervain após tratamento cirúrgico da síndrome do túnel do carpo

Abstract Objective To evaluate the open surgical treatment for carpal tunnel syndrome as a risk factor for the development of stenosing tenosynovitis that results in trigger finger and De Quervain disease. Materials and Methods A retrospective study analyzing the medical records of patients submitted to open surgical release of carpal tunnel syndrome between 2010 and 2021 in a secondary- and tertiary-level hospital. The following data were collected: pathological history, duration of the follow-up after the surgical treatment for carpal tunnel syndrome, development of trigger finger or De Quervain tenosynovitis, affected fingers, and the interval between the end of surgery and symptom onset. Results We evaluated 802 patients of both genders and with a mean age of 50.1 (±12.6) years. The mean follow-up was of 13 (±16.4) months. The mean time until the development of trigger finger was of 61.4 months, and of 73.7 months for De Quervain disease. The incidence of development of De Quervain disease was of 4.12%, and for trigger finger it was of 10.2%. The most affected digits were the thumb (47.6%), the middle (24.4%), and the ring finger (8.54%). Age was the only factor that showed an association with the risk of developing trigger finger, with an increase of 2% for each increase in age of 1 year. Conclusion The incidence rates for the development of De Quervain disease (4.12%) and trigger finger (10.2%) after the surgical treatment for carpal tunnel syndrome were like those described in the literature. Only age was a factor that influenced the development of trigger finger.

Resultados: Foram revisados 14 estudos, que eram compostos de 12 artigos e duas cartas aos editores. Conclusão: O tratamento mais citado foi a injeçãode corticosteroides, e se observou que as aplicações com doses maiores geram respostas de maior sucesso. Em relação a procedimentos cirúrgicos a liberação percutânea da polia A1 apresenta maior nível de recuperação e satisfação, além de menor taxa de recorrência e dor em comparação à injeção de corticosteroides

Introduction: The trigger finger is one of the most common causes of disability in the hands. It has a bimodal distribution in patients under eighteen years of age and adults in the fifth and sixth decades of life. Conservative trigger finger treatment modalities include modification of the patient's manual activity, exercise protocols for manual therapy, corticosteroid injection, oral or injectable non-steroidal anti-inflammatory drugs, and immobilization with the use of orthotics. While surgical management consists of the open or percutaneous release of the A1 pulley. Objective: To synthesize, through a review of scientific literature, evidence on trigger finger treatment. Methodology: We evaluated the clinical trials published in the last five years (2017-2022), obtained from the PUBMED database using the following search strategy: "Trigger finger"[title]. Results: 14 studies were reviewed, which were composed of 12 articles and two letters to the editors. Conclusion: The most cited treatment was corticosteroid injection, and it was observed that applications with higher doses generate more successful responses. In relation to surgical procedures, the percutaneous release of the A1 pulley presents a higher level of recovery and satisfaction, as well as a lower rate of recurrence and pain compared to corticosteroid injection

Relação entre desmame precoce, desenvolvimento de hábitos bucais deletérios e maloclusões na infância / Relationship between early weaning, development of harmful oral habits and malocclusions in childhood

Objetivo: o objetivo desta pesquisa foi analisar a associação do tempo de aleitamento materno com a prática de hábitos deletérios e o desenvolvimento de maloclusões na primeira infância. Materiais e Métodos: foram aplicados 171 formulários às mães com 18 anos ou mais que acompanharam o processo de amamentação de seu(s) filho(s) de 4 a 10 anos de idade. O questionário foi composto por 22 perguntas, sendo 15 específicas e relacionadas ao aleitamento, hábitos deletérios da criança (uso de chupeta, sucção de dedo e sucção do próprio lábio) e maloclusões específicas (mordida cruzada posterior, mordida cruzada anterior e mordida aberta). Resultados: a prevalência da amamentação exclusiva por 6 meses ou mais foi de 52%, enquanto 29,8% das crianças foram amamentadas de 0 a 5 meses e 18,2% nunca foram amamentadas no seio exclusivamente. Quanto a alimentação complementar, grande parcela (37,4%) encontrada evidenciou início após os 6 meses; 57,9% das mães relataram algum tipo de dificuldade para amamentar e 34,5% das crianças fizeram uso de chupeta. Em relação aos hábitos deletérios, 10% desenvolveram sucção de dedo. O relato de desenvolvimento de maloclusões foi de 9,4% das crianças com mordida cruzada posterior; 7,6% mordida cruzada anterior e 18,7% mordida aberta anterior. Conclusão: sendo assim, é possível inferir que o tempo preconizado pela Organização Mundial da Saúde para aleitamento materno exclusivo foi fundamental para o não desenvolvimento de hábitos deletérios e maloclusões. Em contrapartida, quanto mais cedo a introdução de alimentos complementares, e a interrupção do aleitamento exclusivo nos seis primeiros meses, maior o risco do desenvolvimento de hábitos e consequentemente maloclusões.

Objective: the objective of this research was to analyze the association of breastfeeding duration with the practice of deleterious habits and the development of malocclusions in early childhood. Materials and Methods: a total of 171 forms were applied to mothers aged 18 years or older who followed the breastfeeding process of their child(ren) between 4 and 10 years of age. The questionnaire consisted of 22 questions, 15 of which were specific and related to breastfeeding, the child's deleterious habits (use of a pacifier, finger sucking and lip sucking) and specific malocclusions (posterior crossbite, anterior crossbite and open bite). Results: the prevalence of exclusive breastfeeding for 6 months or more was 52%, while 29.8% of children were breastfed from 0 to 5 months and 18.2% were never exclusively breastfed. As for complementary feeding, a large portion (37.4%) found to start after 6 months; 57.9% of the mothers reported some type of difficulty in breastfeeding and 34.5% of the children used a pacifier. Regarding deleterious habits, 10% developed finger sucking. The report of development of malocclusions was 9.4% of children with posterior crossbite; 7.6% anterior crossbite and 18.7% anterior open bite. Conclusion: therefore, it is possible to infer that the time recommended by the World Health Organization for exclusive breastfeeding was fundamental for the non-development of deleterious habits and malocclusions. On the other hand, the earlier the introduction of complementary foods and the interruption of exclusive breastfeeding in the first six months, the greater the risk of developing habits and, consequently, malocclusions.

Comparison of wire versus Nylon in Bonny-Mallet Finger treated with pull-out surgery.

INTRODUCTION: Zone I extensor tendon lesion accompanies an avulsion fracture of the bone insertion. A common complication of traditional pull-out is the necrosis of the site of the button in the finger pad. Zhang described an alternative way of anchoring the cerclage to the Kirschner Wire (K-wire) to relieve the pressure in the finger pad. He describes the use of wire cerclage, for fracture reduction. The objective of this paper is to perform a comparison between wire and nylon using Zhang pull-out technique. MATERIAL AND METHODS: We performed a cohort study comparing Nylon versus Wire in Zhang technique. Comparing cosmetic satisfaction, stiffness, residual pain, and Crawford scale. RESULTS: When comparing the outcomes between both groups, we found no statistical difference in cosmetic satisfaction (p = 0.285), stiffness (p = 0.460), and residual pain (p =1.000), overall complications (p = 1.000), or Crawford scale (p = 1.000). We only found a significant statistical difference in pain when removing the cerclage, being greater in Group B (p = 0.008). CONCLUSIONS: We found no significant outcome difference between nylon and wire cerclage. However, at the time of removing it, patients experience less pain.

INTRODUCCIÓN: Una complicación común del pull-put tradicional es la necrosis del sitio del botón en la yema del dedo. Zhang describió una forma alternativa de anclar el cerclaje al clavo de Kirschner para aliviar la presión en la yema del dedo. Describe el uso de cerclaje de alambre para la reducción de fracturas. El objetivo de este trabajo es realizar una comparación entre el alambre y el nailon utilizando la técnica de extracción de Zhang. MATERIAL Y MÉTODOS: Realizamos un estudio de cohorte comparando la técnica de nailon versus alambre en Zhang. Comparación de satisfacción cosmética, rigidez, dolor residual y escala de Crawford. RESULTADOS: Al comparar los resultados entre ambos grupos, no encontramos diferencias estadísticas en la satisfacción cosmética (p = 0.285), rigidez (p = 0.460) y dolor residual (p = 1.000), complicaciones generales (p = 1.000) o escala de Crawford (p = 1.000). Solo encontramos una diferencia estadística significativa en el dolor al retirar el cerclaje, siendo mayor en el Grupo B (p = 0.008). CONCLUSIONES: No encontramos diferencias significativas en los resultados entre el cerclaje de nailon y el cerclaje con alambre. Pero, al momento de retirarlo, los pacientes experimentan menos dolor. Tipo de estudio: terapéutico Nivel de evidencia III.

Fibrolipomatous hamartoma of the median nerve: a case report and literature review / Hamartoma fibrolipomatoso del nervio mediano: reporte de un caso y revisión de la literatura

Abstract Fibrolipomatous hamartoma (FLH) of the nerve, also known as lipomatosis of the nerve, neurofibrillary lipomatous lesion, or intraneural lipoma, is a rare benign soft tissue tumor which mainly occurs in the nerves of the upper limb, especially in the median nerve. In April 2021, a 30-year-old male patient was secondly admitted to our hospital and underwent his third surgery, due to the recurrence of a mass and pain in the right palm, noticeable swelling and numbness of the right index and ring fingers, and limited flexion and extension activities of the right ring finger. He first visited our hospital in December 2017 due to a mass and pain in the right palm and swelling and numbness of the right index and ring fingers. When the clinician asked for the patient medical history, his parents stated that his right middle finger was swollen after birth. When the patient was ten years old; he was diagnosed with "macrodactyly" at the local county hospital, not in our hospital, and subsequently, the middle finger was amputated at the metacarpophalangeal joint level at the local county hospital. The postoperative pathological examination was not performed at that time, which was the first surgery the patient received. FLH is clinically rare, and its exact epidemiology and etiology are poorly understood. FLH is highly suspected in cases where a painless mass is present in the wrist, combined with macrodactyly. Magnetic resonance imaging and pathological examination are helpful in clarifying the diagnosis. Although FLH is a benign tumor, an individual treatment plan is the best choice according to the severity of the patient's symptoms. Therefore, further exploration and understanding of this disease by clinicians radiologists, and pathologists is necessary.

Resumen El hamartoma fibrolipomatoso (FLH) del nervio, también conocido como lipomatosis del nervio, lesión neurofibrilar lipomatosa, o lipointraneural, es un tumor benigno de tejido blando poco frecuente, que se presenta principalmente en los nervios del miembro superior, especialmente en el nervio mediano. En abril de 2021, un paciente masculino de 30 años fue ingresado por segunda vez en nuestro hospital y sometido a su tercera cirugía debido a la recurrencia de una masa y dolor en la palma derecha, evidente hinchazón y entumecimiento de los dedos índice y anular derecho y limitadas actividades de flexión y extensión del dedo anular derecho. En diciembre de 2017, visitó por primera vez nuestro hospital debido a una masa y dolor en la palma derecha, y a la hinchazón y entumecimiento de los dedos índice y anular derecho. Cuando el clínico preguntó la historia clínica del paciente, sus padres declararon que su dedo medio derecho estaba hinchado después del nacimiento, y cuando el paciente tenía 10 años, fue diagnosticado con "macrodactilia" en el hospital local del condado, no en nuestro hospital Posteriormente, el dedo medio fue amputado a nivel de la articulación metacarpofalángica en el hospital comarcal local, pero no se realizó la patología postoperatoria en ese momento, siendo ésta la primera cirugía a la cual se sometió el paciente. La FLH es clínicamente rara, y su epidemiología y etiología exactas no se entienden bien. En los casos que presentan una masa indolora en la muñeca, combinada con macrodactilia, se sospecha de FLH. La resonancia magnética y la patología son útiles para aclarar el diagnóstico. Aunque la FLH es un tumor benigno, el plan de tratamiento individual es la mejor opción de acuerdo con la gravedad de los síntomas del paciente. Por lo tanto, es necesaria una mayor exploración y comprensión de esta enfermedad por parte de médicos, radiólogos y patólogos.

Condicionantes del éxito terapéutico de las infiltraciones de corticoides en el síndrome del dedo en resorte / Determinants of Therapeutic Success of Corticoids Injections in Trigger Finger Syndrome

Antecedentes y objetivo: El dedo en resorte es un motivo de consulta frecuente en el que las infiltraciones de corticoides juegan un papel terapéutico relevante en los grados de severidad intermedios cuando el tratamiento conservador no ha funcionado. Sin embargo, no existen criterios que permitan seleccionar qué pacientes se beneficiarán más de este procedimiento. El objetivo de nuestro estudio es identificar los condicionantes de éxito terapéutico de las infiltraciones de corticoides en estos pacientes. Materiales y métodos: Diseñamos un estudio prospectivo longitudinal basado en práctica clínica habitual con pacientes adultos, con diagnóstico clínico de dedo en resorte grado II o III, a quienes se les realizó una infiltración de 20mg de acetato de triamcinolona. Las variables desenlace fueron el alcanzar un grado Quinnell I o reducir en al menos una categoría la severidad del cuadro clínico, 2 meses después del procedimiento. Para determinar los condicionantes del alcance de los objetivos se realizó una modelización predictiva de regresión logística binaria utilizando aquellas variables que tuvieron una satisfactoria correlación univariante. Resultados: Se incluyeron 74 pacientes a lo largo de 3 años, 42 de los cuales (61,8%) tenían un grado Quinnell III. Tras la infiltración, 22 (32,4%) alcanzaron la resolución completa y 50 (73,5%), la resolución parcial. Las variables engrosamiento tendinoso (HR: 10,72; IC 95%: 2,88-39,93; p<0,001) y tiempo de evolución (HR: 1,23; IC 95%: 1,02-1,49; p=0,027) demostraron ser condicionantes predictoras del éxito terapéutico en la resolución completa. Para la modelización para resolución parcial las mismas variables demostraron ser condicionantes predictoras (HR: 5,57; IC 95%: 1,38-22,41; p=0,016 y HR: 1,18; IC 95% 0,99-1,41; p=0,051, respectivamente). El engrosamiento de la polea no demostró capacidad predictiva en ninguno de los 2 modelos.(AU)

Background and objective: Trigger finger is a frequent complaint in which corticosteroid infiltrations play a relevant therapeutic role in intermediate degrees of severity when conservative treatment has not worked. However, there are no criteria to select which patients will benefit most from this procedure. The present study aimed to identify the factors leading to the therapeutic success of corticosteroid infiltration in these patients. Materials and methods: We designed a prospective longitudinal study based on routine clinical practice with adult patients with a clinical diagnosis of trigger finger grade II or III on the Quinnell scale, who underwent an infiltration of 20mg of triamcinolone acetate. The outcome variables were to achieve a Quinnell grade I or reduce the severity of the symptoms by at least one category two months after the procedure. To identify the determinants of complete or partial therapeutic success, binary logistic regression predictive modelling was performed using those variables that had a satisfactory univariate correlation. Results: 74 patients were included over three years, 42 of whom (61.8%) were classified as Quinnell grade III. After infiltration, 22 (32.4%) achieved complete resolution and 50 (73.5%) partial resolution. The variables tendon thickening (HR 10.72; 95%CI 2.88-39.93; P<.001) and progression time (HR 1.23; 95%CI 1.02-1.49; P=.027) proved to be predictors of therapeutic success in complete resolution. For the modelling for partial resolution, the same variables proved to be determining predictors (HR 5.57; 95%CI 1.38-22.41; P=.016 and HR 1.18; 95%CI .99-1.41; P=.051, respectively). Pulley thickening did not demonstrate predictive ability in either model.(AU)

Trigger Finger Treatment / Tratamento do Dedo em Gatilho

Abstract Trigger finger is a frequent condition. Although tenosynovitis and the alteration of pulley A1 are identified as triggering factors, there is no consensus on the true cause in the literature, and its true etiology remains unknown. The diagnosis is purely clinical most of the time. It depends solely on the existence of finger locking during active bending movement. Trigger finger treatment usually begins with nonsurgical interventions that are instituted for at least 3 months. In patients with initial presentation with flexion deformity or inability to flex the finger, there may be earlier indication of surgical treatment due to pain intensity and functional disability. In the present review article, we will present the modalities and our algorithm for the treatment of trigger finger.

Resumo O dedo em gatilho é uma afecção frequente. Não obstante a tenossinovite e a alteração da polia A1 serem identificados como fatores desencadeantes, não há consenso sobre a verdadeira causa na literatura, sendo que a sua verdadeira etiologia permanece desconhecida. O diagnóstico é puramente clínico na maior parte das vezes. Ele depende unicamente da existência do travamento do dedo no decorrer da movimentação flexão ativa. O tratamento do dedo em gatilho geralmente se inicia com intervenções não cirúrgicas que são instituídas por pelo menos 3 meses. Nos pacientes em quem haja apresentação inicial com deformidade em flexão ou incapacidade de flexão do dedo, pode haver indicação mais precoce do tratamento cirúrgico em razão da intensidade do quadro álgico e da incapacidade funcional do paciente. No presente artigo de revisão, apresentaremos as modalidades e o nosso algoritmo para o tratamento do dedo em gatilho.

Síndrome del dedo azul: de la piel a lo multisistémico / Blue digit syndrome: from skin to a multisystemic etiology

El signo del dedo azul (SDA) es una condición poco frecuente causada principalmente por la oclusión de la vasculatura periférica. Clínicamente puede manifestarse como una coloración azulada o eritrocianótica en uno o varios dedos en ausencia de traumatismo y condiciones propias de congelación. Las etiologías son múltiples e incluyen obstrucción del flujo arterial, disminución del flujo venoso y alteración en la viscosidad sanguínea. La importancia de reconocer el signo como motivo de consulta radica en encaminar un diagnóstico temprano e instaurar un tratamiento que evite la evolución natural de la enfermedad hacia la necrosis, amputación o muerte del paciente. Proponemos un algoritmo diagnóstico para reconocer los elementos de la historia clínica que guíen la etiología y los paraclínicos disponibles desde el Servicio de Urgencias.

Blue finger sign (BFS) is a rare condition caused mainly by occlusion of peripheral vasculature. Clinically it may manifest as a bluish, or erythrocyanotic discoloration of one or more fingers in the absence of trauma and freezing conditions. The etiologies are multiple and include arterial flow obstruction, decreased venous flow, and altered blood viscosity. The importance of recognizing the sign as a reason for consultation lies in the early diagnosis and the establishment of a treatment that finally avoids the natural evolution of the disease towards necrosis and finally amputation or death of the patient. We propose a diagnostic algorithm based on recognizing elements of the clinical history that guide the etiology and paraclinical available from the Emergency Department.

Síndrome de compresión del túnel del carpo y tercer dedo en gatillo secundarios a un fibrolipoma encapsulado de la muñeca: reporte de un caso / Carpal tunnel compression syndrome and third finger in trigger secondary to an encapsulated fibrolipoma of the wrist: a case report

Resumen: Introducción: la asociación del síndrome del túnel del carpo con tenosinovitis estenosante de la mano es muy rara, aún más, si es generada por un fibrolipoma a nivel del túnel del carpo. El estudio de imagen para detectar este tipo de lesiones en la mano incluye: desde una radiografía con proyección para el túnel del carpo, tomografía axial computarizada y resonancia magnética nuclear; pero éstos no se utilizan habitualmente para el estudio protocolizado del síndrome del túnel del carpo y mucho menos para los dedos en gatillo. Objetivo: el objetivo de este trabajo es reportar un caso en el cual se presenta la sintomatología característica de un síndrome de túnel del carpo, asociada a tercer dedo en gatillo, el cual se maneja con la liberación del nervio mediano por medio de un abordaje de mínima invasión, además de la polea A1. Caso clínico: la paciente persistió con ambas alteraciones y en la revisión secundaria se detectó bloqueo a nivel de la muñeca. Se intervino nuevamente a la paciente y se encontró una tumoración encapsulada, que midió 3.0 × 2.0 × 1.0 cm, con superficie externa lisa, blanquecina, de aspecto ovoide y consistencia blanda «ahulada¼. El estudio anatomopatológico la identificó como un fibrolipoma encapsulado que ocasionó la compresión nerviosa y el bloqueo del tendón flexor. Conclusión: la importancia de este reporte de caso radica en agregar los tumores al repertorio etiológico, que además pueden provocar una compresión del nervio mediano y en que sean aún menos frecuentes como causa de atrapamiento de los tendones flexores de la mano.

Abstract: Introduction: the association of carpal tunnel syndrome with stenosing tenosynovitis of the hand is very rare, even more, if it is generated by a fibrolipoma at the carpal tunnel. The imaging study useful to detect this type of hand injuries are X-ray screening for carpal tunnel, computed tomography and magnetic resonance imaging. But these are not commonly used for the study of protocolized carpal tunnel syndrome and much less trigger finger. Objective: the aim of this work is to report a case of a middle-aged female with carpal tunnel syndrome characteristic symptoms, associated with the third trigger finger; she was handled with the release of the median nerve by a minimally invasive approach, in addition to the A1 pulley release. Clinical case: the patient persists with both problems and at a secondary surgical review, we detected wrist locking sensation. The patient was reoperated finding an ovoid encapsulated tumor, measuring 3.0 × 2.0 × 1.0 cm, with smooth outer surface, whitish appearance, and soft rubbery consistency. The biopsy pathology outlines identified an encapsulated fibrolipoma, causing nerve compression and locking flexor tendon. Conclusion: the importance of this writing is in adding tumors to the etiological repertoire, which can cause compression of the median nerve and even less frequent as a cause of the flexor tendons of the hand snagging.

Aneurisma verdadero aislado en arteria femoral superficial asociado a síndrome del dedo azul / True isolated aneurysm in superficial femoral artery associated with blue finger syndrome

Los aneurismas femorales son raros y más aún en la arteria femoral superficial. Estos representan solo el 3 por ciento de todos los aneurismas periféricos. El objetivo de este trabajo fue presentar el caso de un aneurisma verdadero aislado en arteria femoral superficial asociado a síndrome del dedo azul. Se reporta un paciente masculino de 75 años, fumador, con antecedentes patológicos personales de hipertensión arterial, que llega remitido con urgencia desde su área de salud por presentar cambios de coloración (cianosis), frialdad y dolor en la planta y los dedos del pie derecho (microembolias distales). En la tomografía computarizada contrastada se observó aneurisma aislado en la arteria femoral superficial de 4,5 cm de diámetro transversal. Se decidió operar al paciente y se realizó aneurismectomía con interposición de injerto protésico con politetrafluoroetileno, con una configuración de anastomosis término-terminal. Tuvo una evolución clínica posoperatoria inmediata y tardía satisfactoria. Entre los aneurismas femorales, los que afectan a la arteria femoral superficial están menos descritos y pueden complicarse con trombosis, embolización distal o rotura. Existe un alto consenso para su reparación, al eliminar la fuente embólica, prevenir la trombosis, tratar la rotura, eliminar cualquier efecto de masa y restaurar la perfusión de la extremidad distal. Dado que el síndrome del dedo azul puede ser la primera manifestación de esta enfermedad, su rápido reconocimiento, diagnóstico precoz de la fuente embolígena y tratamiento médico-quirúrgico pueden evitar la amputación mayor o la muerte del paciente(AU)

Femoral aneurysms are rare and even more so in the superficial femoral artery. These account for only 3 percent of all peripheral aneurysms. The objective of this study was to present the case of an true isolated aneurysm in the superficial femoral artery associated with blue finger syndrome. A 75-year-old male patient, smoker, with a personal pathological history of arterial hypertension, is reported to be urgently referred from his health area for presenting changes in coloration (cyanosis), coldness and pain in the sole and toes of the right foot (distal microembolisms). The contrasted computed tomography showed an isolated aneurysm in the superficial femoral artery of 4.5 cm transverse diameter. It was decided to operate on the patient and aneurysmectomy was performed with interposition of prosthetic graft with polytetrafluoroethylene, with a configuration of termino-terminal anastomosis. He had a satisfactory immediate and late postoperative clinical evolution. Among femoral aneurysms, those affecting the superficial femoral artery are less described and can be complicated by thrombosis, distal embolization, or rupture. There is a high consensus for their repair by removing the embolic source, preventing thrombosis, treating rupture, eliminating any mass effects and restoring perfusion of the distal limb. Since blue finger syndrome may be the first manifestation of this pathology, its rapid recognition, early diagnosis of the emboligenic source and medical-surgical treatment can prevent major amputation or death of the patient(AU)

Infiltración comisural dorsal en el tratamiento del pulgar y los dedos en resorte. Estudio de una cohorte prospectiva / Out-of-sheath corticosteroid injections through the dorsal webspace for trigger finger and trigger thumb. A prospective cohort study

Antecedentes y objetivo: Las infiltraciones de corticoides son efectivas en el tratamiento de los dedos en gatillo pero el dolor percibido por el paciente durante la inyección es un efecto acompañante siempre presente. El objetivo de este estudio fue evaluar la efectividad y el dolor percibido durante una infiltración corticoidea depositada fuera de la vaina tendinosa utilizando la técnica comisural dorsal. Material y método: Se incluyeron 126 pacientes consecutivos. Se realizó una infiltración esteroidea subcutánea (fuera de la vaina) a través de la comisura dorsal. En los casos en que los signos o síntomas persistieron, se ofreció una segunda infiltración. Se registró el dolor percibido durante la infiltración mediante la escala visual analógica, el cuestionario DASH antes del tratamiento y al final de seguimiento, la tasa de éxito y las complicaciones. Resultados: Fueron 86 mujeres y 40 hombres con una edad media de 61 años. La puntuación media del dolor durante la infiltración fue de 3,8. Doce pacientes se perdieron durante el seguimiento. El éxito global fue del 68% y el éxito tras una única inyección fue del 54%. El mejor resultado se obtuvo en el dedo anular. Los pacientes que no habían sido operados previamente del síndrome del túnel carpiano respondieron mejor. No se objetivaron complicaciones. Conclusiones: La infiltración esteroidea fuera de la vaina tendinosa y utilizando la técnica comisural dorsal es efectiva y segura en el tratamiento de los dedos en resorte. Parece ser menos dolorosa que los resultados publicados para la técnica palmar sobre la línea media, aunque esto debe evaluarse en un estudio diseñado para ello.(AU)

Background and objective: Steroid injections are effective in the treatment of trigger digits but the pain during the injection is an always-present accompanying effect. The aim of this study was to assess the effectiveness and perceived pain during an out-of-sheath corticosteroid injection through the dorsal webspace in the treatment of trigger digits. Material and method: A total of 126 consecutive patients were included. A subcutaneous (out-of-sheath) corticosteroid injection was performed through the dorsal webspace in all digits. In cases where signs or symptoms persisted, a second injection was offered. Visual analog scale for pain during the injection, DASH questionnaire, success rate and complications were collected. Results: There were 86 women and 40 men with a mean age of 61 years. The mean visual analog scale for pain during the injection was 3.8. Twelve patients were lost to follow-up. The overall success was 68% and success after a single injection was 54%. The best result was achieved on the ring finger. Patients who were not previously operated on carpal tunnel syndrome responded better. No complications were noted. Conclusions: The extra-sheath corticosteroid injection through the dorsal webspace is effective and safe. It seems to be less painful than the reported scores for the palmar midline technique although it should be assessed in a comparative study.(AU)

Lesiones de punta de dedo: experiencia en el manejo en los últimos 5 años en un centro pediátrico / Fingertip injuries: experience in handling the last 5 years in a pediatric center

Las lesiones de punta de dedo son comunes en pacientes pediátricos que acuden a salas de Emergencia; son causadas por accidentes en el hogar y con aplastamiento en puerta como principal mecanismo de trauma. El tratamiento se realiza individualizado por cirujanos plásticos y cirujanos pediátricos en dependencia de la herida y el compromiso tisular. El propósito de este estudio es describir el manejo de pacientes con lesiones de punta de dedo en un centro pediátrico. Se realizó un análisis de historias clínicas en el período entre enero 2015 y diciembre 2020, se evaluaron 228 pacientes atendidos en el Hospital de Niños Dr. Roberto Gilbert Elizalde, en Guayaquil, Ecuador. Los resultados incluyen un predominio de pacientes en edad preescolar (67%), masculinos (56%) y de mano derecha (53%). Los dedos más afectados fueron el medio y anular. Los procedimientos fueron realizados por cirujanos plásticos (55%) y la técnica electiva fue bajo anestesia general. La extensión del daño involucró tejidos blandos (92%), avulsión de uña (29%) y fracturas asociadas (15%). El 3% de los pacientes presentó complicaciones que requirieron seguimiento. El tipo de reparo se seleccionó en dependencia de la extensión de la herida, se realizaron suturas simples (37%) y suturas complejas con reparo de la uña (27%). Nuestros datos son similares a los descritos en la literatura internacional, con buenos resultados a largo plazo, menor tasa de complicaciones y respuestas similares en los reparos realizados por cirujanos plásticos y cirujanos pediatras.

Fingertip injuries are common in pediatric patients who present to the emergency room. They are usually caused by accidents at home, being door-crush the main mechanism. Treatment is performed on an individual basis, by a Plastic or General Pediatric Surgeon, according to the wound findings and tissue involvement. The purpose of this study is to describe the management on a pediatric center in patients with a fingertip wound. A descriptive and retrospective analysis of medical records was carried out from January 2015 until December 2020. In this period 228 patients were seen in the Dr. Roberto Gilbert Elizalde Children´s Hospital in Guayaquil, Ecuador. A high incidence was found in the preschool age with 67% of cases. The injuries were more common in males (56 %) and more predominant on the right hand (53%). The most affected fingers were the middle and annular. Procedures were mostly performed by Pediatric Surgeons (55%) and the elective technique was under general anesthesia. Damage extension of the fingertip included soft tissues in 92% of patients, nail avulsion in 29% and associated fractures in 15%. Only 3% of patients developed complications that required follow up. The type of repair was selected according to the extension of the injury. Mostly simple sutures (37%) and complex sutures with nail repair (27%)were used.Our data is similar to the one found in international literature, with good long-term outcomes, minor complications and similar results when the repair was performed by a Plastic or Pediatric surgeon

Determinants of therapeutic success of corticoids injections in trigger finger syndrome.

BACKGROUND AND OBJECTIVE: Trigger finger is a frequent complaint in which corticosteroid infiltrations play a relevant therapeutic role in intermediate degrees of severity when conservative treatment has not worked. However, there are no criteria to select which patients will benefit most from this procedure. The present study aimed to identify the factors leading to the therapeutic success of corticosteroid infiltration in these patients. MATERIALS AND METHODS: We designed a prospective longitudinal study based on routine clinical practice with adult patients with a clinical diagnosis of trigger finger grade II or III on the Quinnell scale, who underwent an infiltration of 20 mg of triamcinolone acetate. The outcome variables were to achieve a Quinnell grade I or reduce the severity of the symptoms by at least one category two months after the procedure. To identify the determinants of complete or partial therapeutic success, binary logistic regression predictive modelling was performed using those variables that had a satisfactory univariate correlation. RESULTS: 74 patients were included over three years, 42 of whom (61.8%) were classified as Quinnell grade III. After infiltration, 22 (32.4%) achieved complete resolution and 50 (73.5%) partial resolution. The variables tendon thickening (HR 10.72; 95%CI 2.88-39.93; P < .001) and progression time (HR 1.23; 95%CI 1.02-1.49; P = .027) proved to be predictors of therapeutic success in complete resolution. For the modelling for partial resolution, the same variables proved to be determining predictors (HR 5.57; 95%CI 1.38-22.41; P = .016 and HR 1.18; 95%CI .99-1.41; P = .051, respectively). Pulley thickening did not demonstrate predictive ability in either model. DISCUSSION AND CONCLUSIONS: Our results indicate that the demonstration of finger flexor apparatus thickening is the main determining factor for the success of corticosteroid infiltrations in this pathology. This is in agreement with the histological findings of specimens obtained from both tenosynovial and pulley tissue. In the former, in addition to an infiltrate of inflammatory characteristics, the presence of chondrocytoid cells producing hyaluronic acid is demonstrated. Although the therapeutic success of infiltrations in previous studies reaches 70%, the recurrence rate is similar after 12 months. The selection of patients with tendon thickening ensures therapeutic success in the short term, could reduce recurrence in the long term, and avoid delay in release surgery.
