REHABILITATION OF HAND BURN PATIENTS IMPLEMENTING OCCUPATIONAL THERAPY

Patients with burns to their hands require rehabilitation for their early return to work and good quality of life. The aim of this study was to evaluate the effect of early intervention with occupational therapy in patients with burns to their hands. This study included 60 patients with second or third degree hand burns. Patients were included to the study 2 weeks after their burn wounds and grafted areas had healed. They had 3 occupational therapy sessions per week for 8 weeks. These sessions included active and passive range of motion exercises, stretching exercises, active resistive exercises and practicing activities of daily living. Before and after the 8 weeks of occupational therapy using the DASH questionnaire, functionality of the hand was assessed. Before intervention with occupational therapy, the average DASH score was 62.5, and after 8 weeks of occupational therapy it was 30.4 (average difference between the pre-intervention and postintervention DASH scores is 32.1 points, p < 0.001). After 8 weeks of occupational therapy, patients performed daily living activities with relatively very less difficulty, and functionality of the hands was also increased. This study suggests that early intervention with rehabilitative therapies is beneficial and may result in improved hand function

Aplicación de la técnica WALANT en las cirugías de mano / Use of WALANT Technique in Hand Surgeries

Introducción: En los últimos años la anestesia local sin torniquete y con el paciente despierto, técnica conocida por WALANT (por sus siglas en inglés), ha ganado mucha popularidad en las cirugías de la mano y la muñeca. Objetivo: Reportar nuestra experiencia con el uso de la técnica WALANT, a fin de prescindir del uso del torniquete en las cirugías de la mano. Métodos: En noviembre del 2020 fueron intervenidos 30 pacientes por diversas enfermedades ortopédicas, entre las que figuraron: dedos en resorte, síndrome del túnel carpiano, tenovaginitis estenosante del pulgar, gangliones del carpo y amputación del tercer radio por rigidez en extensión postraumática, entre otras. Para la evaluación de la técnica tuvimos en cuenta: tiempo quirúrgico, magnitud del sangrado, dolor durante la infiltración anestésica, la intervención, y en las primeras 24 horas del postoperatorio, la necesidad de refuerzo anestésico, uso de isquemia, complicaciones y nivel de satisfacción del paciente. Resultados: Los resultados obtenidos con esta técnica anestésica son semejantes a otras, con las ventajas que el sangrado es leve, no hay que utilizar isquemia, el tiempo quirúrgico es menor y el efecto anestésico duró entre 10 y 12 horas en todos los pacientes. En ninguno de los pacientes hubo necesidad de refuerzo anestésico. Conclusiones: Se demuestra la efectividad de la técnica WALANT en las cirugías de mano. Con ella se disminuye el gasto de materiales para el acto quirúrgico, así como de personal, es de fácil aplicación y disminuyen las sensaciones desagradables y los peligros del uso de isquemia en los pacientes(AU)

Introduction: Currently, the use of local anaesthetic with no tourniquet and wide awake patient (Wide Awake Local Anaesthetic No Tourniquet - WALANT) has gained popularity in surgeries of the hand and wrist. Objective: To report our experience in the use of WALANT technique in order to discard the use of tourniquet in hand surgeries. Method: In November 2020, thirty patients underwent surgery due to different orthopaedic conditions, among them trigger fingers, carpal tunnel syndrome, stenosing tenovaginitis of the thumb, carpal ganglion and amputation of the third radius due to post trauma stiffness, among others. In order to assess this technique, we considered surgical time, volume of bleeding, pain during anesthetic infiltration, intervention and the need for additional anesthetic during the first 24 hours after surgery; we considered also ischemia, complications and level patient´s satisfaction. Results: This technique had similar results to others; however, the bleeding is mild, there is no need for ischemia, the surgical time is lesser and the anesthetic effect lasted 10 to 12 hours in all patients. None of them required additional anesthetic. All subjects felt the initial infiltration but none complained of pain during the rest of the anesthetic injection or during the surgical act. There were no complications. Conclusions: The effectiveness of WALANT technique in hand surgeries is shown. The cost of materials for the surgical act is reduced with it, as well as the surgical staff, it is easy to use and unpleasant sensations and dangers of the use of ischemia in patients are reduced(AU)

A Modified Flexor Tendon Suture Technique Combining Kessler and Loop Lock Flexor Tendon Sutures

OBJECTIVES: In the present study, a novel single knot tenorrhaphy was developed by combining the modified Kessler flexor tendon suture (MK) with the loop lock technique. METHODS: A total of 48 porcine flexor digitorum profundus tendons were collected and randomly divided into six groups. The tendons were transversely cut and then repaired using six different techniques, the MK method, double knot Kessler-loop lock flexor tendon suture (DK), and single knot Kessler-loop lock flexor tendon suture (SK), each in combination with the epitendinous suture (P), and the same three techniques without P. Furthermore, by performing the load-to-failure tests, the biomechanical properties and the time taken to complete a repair, for each tenorrhaphy, were assessed. RESULTS: Compared to the MK+P method, DK+P was more improved, thereby enhancing the ultimate tensile strength. The SK+P method, which required fewer knots than DK+P, was easier to perform. Moreover, the SK+P repair increased the force at a 2-mm gap formation, while requiring lesser knots than DK+P. CONCLUSION: As opposed to the traditional MK+P method, the SK+P method was improved and exhibited better biomechanical properties, which may facilitate early mobilization after the repair.

Manejo artroscópico de pseudoartrosis de escafoides con deformidad en joroba: técnica quirúrgica y serie de casos / Arthroscopic treatment for scaphoid pseudarthrosis with humpback: surgical technique and case series

INTRODUCCIÓN: La pseudoartrosis de escafoides con deformidad en joroba es una patología compleja que si no recibe tratamiento oportuno puede llevar a una deformidad avanzada, con colapso del carpo produciendo un deterioro significativo en la función de la muñeca. En la actualidad se considera como tratamiento estándar la reducción abierta de la deformidad utilizando injerto estructural. El OBJETIVO del presente trabajo es describir una técnica de reducción artroscópica, utilizando injerto no estructural para la no-unión de escafoides con deformidad en joroba. Se muestran los resultados obtenidos en una serie de casos manejados con la técnica propuesta. MATERIAL Y MÉTODO: Estudio retrospectivo de una serie de casos de pacientes diagnosticados con pseudoartrosis de escafoides con deformidad en joroba manejados con la técnica propuesta. Se describe la técnica quirúrgica. Se utiliza el programa STATA 15 para el análisis estadístico de los resultados, al igual que test de Wilcoxon para variables no paramétricas. RESULTADOS: Once pacientes de sexo masculino, con edad promedio de 23,4 años, completaron seguimiento promedio de 12 meses. En todos los pacientes se comprobó consolidación de la no-unión mediante Tomografía Computada en un tiempo promedio de 9,1 semanas. Todos los pacientes mejoraron sus rangos de movilidad y ángulos imagenológicos de manera significativa y mejoraron en la prueba funcional de DASH (p » 0.0033). DISCUSiÓN: Se muestra una técnica de reducción percutánea con asistencia artroscópica utilizando injerto no estructural para corregir la no-unión de escafoides con deformidad en joroba produciéndose buenos resultados clínicos con consolidación, en todos los pacientes de nuestra serie, similar a lo encontrado en la literatura internacional. Creemos que esa técnica permite una corrección parcial de la anatomía del carpo y favorece la consolidación ósea al tener las ventajas teóricas de una técnica mínimamente invasiva.

INTRODUCTION: Scaphoid pseudoartrosis with humpback deformity is a complex pathology that if not treated promptly can lead to an advanced deformity with collapse of the carpus producing a significant deterioration in wrist function. At present, open reduction of the deformity using structural bone graft is considered the gold standard of treatment. The AIM of the present study is to describe a surgical technique of percutaneous reduction with arthroscopic assistance using non-structural bone graft for scaphoid non-union with humpback deformity. We present a case series of patients treated with the proposed technique. MATERIAL AND METHODS: Retrospective study of a case series of patients diagnosed with scaphoid pseudarthrosis with humpback deformity treated with the proposed technique. We describe the surgical technique. We used STATA 15 for the statistical analysis and Wilcoxon test for non-parametric variables. RESULTS: 11 male patients, with an average age of 23.4 years, completed an average follow-up of 12 months. Bone healing was confirmed with Computed Tomography in an average time of 9.1 weeks in all of our patients. All patients improved their range of mobility and radiographic measurements significantly and all improved in the DASH functional test (p » 0.0033). DISCUSSION: We describe a technique of percutaneous reduction with arthroscopic assistance using non-structural graft to correct scaphoid non-union with humpback deformity. We found good clinical results and high union rate in all the patients of our series. Similar to what is found in international literature, we believe that this technique allows a partial correction of carpal anatomy and favors bone consolidation by having the advantages of a minimally invasive technique.

Angiosome study of the first digital feet space, for reconstruction of the digital tip

Background: The concept of angiosome explains the anatomical variations that exist between the vessels of different regions of the body and helps to understand the contributions of arterial blood supply to the skin and adjacent structures, dividing the human body into three-dimensional vascular blocks.Methods: This was an observational and descriptive study. In both lower extremities of 5 corpses with adequate tissue preservation in the operating room attached to the teaching area of the National Institute of Forensic Sciences in Mexico City. Angiosome study of the medial neurocutaneous flap of the second toe of both feet was performed.Results: The average, in centimeters, of the surface of the flaps was 1.57 cm x 2.47 cm, the average diameter of the inter-metatarsal digital artery was 1.1 millimeters and the average diameter of the veins draining the angiosome was 1.4 millimeters. The most constant anatomy was that of the nerve, which was present in all cases, with the digital nerve forming the neurosome of the flap.Conclusions: To obtain optimal results in microsurgery transfers, it is necessary to have a technique that is quick for harvesting the flap and with adequate systematization so as not to injure the neurovascular bundle, this is achieved through complete anatomical knowledge, without forgetting the main variants.

Life quality evaluation using "time trade off" method for rheumatoid hands / Avaliando qualidade de vida do paciente com artrite nas mãos pelo método "time trade off"

ABSTRACT Objective: Rheumatoid arthritis is a prevalent disease in the population (range 0.5% to 1%) and involves both orthopedic and rheumatologic treatment. The Time Trade-Off (TTO) technique, which determines the number of years the patient or the professional would be allowed before a successful procedure in terms of life expectancy and value of the procedure, has been gaining ground in clinical protocols. From this standpoint, we sought to compare evaluations provided by the patients, orthopedists, and rheumatologists in determining the TTO and to correlate their responses with the clinical repercussions using previously established scores such as the Brief Michigan Hand Questionnaire and the Disease Activity Score-28 (DAS-28). Methods: A prospective study was conducted that involved 37 patients with rheumatoid arthritis, orthopedists, and rheumatologists. The TTO questionnaire was administered by an independent evaluator for evaluation using the DAS-28 and the Brief Michigan Hand Questionnaire. Results: The descriptive analysis revealed similar medians between the orthopedists, rheumatologists, and patients for single assessments. However, there was a weak correlation between the results from the patient and rheumatologist, the patient and Brief Michigan Questionnaire, and those of the orthopedic surgeon and the DAS-28. Conclusion: Similar median values demonstrated equivalent TTO among the orthopedist, rheumatologist, and patient. However, given the weak correlations between the scores, it was not possible to substitute results using a single evaluation scale. Level of Evidence II, Prognostic Studies.

RESUMO Objetivo: Artrite reumatoide é uma doença prevalente na população (0,5% a 1%), envolvendo tratamento tanto ortopédico, quanto reumatológico. A técnica do "Time Trade Off", que determina a quantidade de anos que o paciente ou o profissional daria para ter sucesso absoluto em determinado procedimento, vem ganhando espaço nos protocolos modernos. Diante disto, comparamos a avaliação dada pelo paciente, pelo ortopedista e pelo reumatologista usando "Time Trade Off" e correlacionamos com repercussão clínica e escores já estabelecidos: Brief Michigan Questionnaire (Anexo I) e Disease Activity Score-28 (DAS-28) (Anexo II). Métodos: Estudo prospectivo com 37 pacientes diagnosticados com artrite reumatoide, que foram submetidos ao questionário "Time Trade Off" pelo ortopedista, pelo reumatologista e por um avaliador independente, e avaliação através do DAS-28 e do Brief Michigan. Resultados: Através da análise descritiva, notou-se medianas semelhantes entre ortopedista, reumatologista e paciente. Entretanto, evidenciou-se correlação fraca entre paciente e reumatologista, paciente e o Brief Michigan; e ortopedista e o DAS-28. Conclusão: Valores de mediana semelhantes demonstram "Time Trade Off" equivalentes entre ortopedista, reumatologista e paciente. Mas, diante das correlações fracas entre os escores, não foi possível substituí-los por uma escala única de avaliação. Nível de Evidência II, Estudo Prognóstico.

Fragmento dorso-ulnar en fracturas de radio distal: clasificación y manejo / Dorso-ulnar fragment in distal radius fractures: classification and treatment

INTRODUCCIÓN: El fragmento dorso-ulnar (FDU) en la fractura intraarticular de radio distal es de especial importancia puesto que implica una alteración en la articulación radio-carpiana así como también en la articulación radio-ulnar distal (RUD), donde la incongruencia articular permanente puede generar secuelas a largo plazo. OBJETIVO: Proponer una clasificación del FDU, definiendo cuándo realizar el procedimiento quirúrgico con asistencia artroscópica, basado en una serie consecutiva de casos operados de fractura del radio distal estudiados con tomografía computada (TC). MÉTODO: Estudio descriptivo de una serie de casos de pacientes operados por fractura del radio distal entre enero del 2015 y diciembre del 2016. En base a eso, se elabora una clasificación del FDU y se sugiere un esquema de manejo específico. Se describe el FDU como aquel fragmento específico ubicado en la esquina dorso-ulnar de la carilla articular del radio distal, con compromiso de más del 30% de la superficie articular RUD y más de 5mm desde el borde ulnar hacia radial de la cortical dorsal del radio observado en el corte axial de la TC preoperatoria. Se considera un fragmento mayor (FM) cuando el rasgo de fractura compromete hacia radial hasta el tubérculo de Lister y se considera fragmento menor (Fm) cuando el rasgo no alcanza a comprometer el tubérculo de Lister. Nuestra propuesta de clasificación reconoce 4 tipos: tipo I (FM sin desplazamiento, en fracturas tipo C de la AO); tipo II (FM con desplazamiento, en fracturas tipo C de la AO); tipo III (Fm independiente del desplazamiento, en fracturas tipo C de la AO) y tipo IV (FM/Fm con desplazamiento, en fracturas tipo B2 de la AO). Esquema de manejo: Tipo I síntesis con placa bloqueada por abordaje palmar, sin obligación de asistencia artroscópica. Tipo II síntesis con placa bloqueada por abordaje palmar, con asistencia artroscópica requerida. Tipo III síntesis percutánea dorsal contornillo canulado, bajo asistencia artroscópica. Tipo IV síntesis dorsal con placa o tornillo mediante abordaje dorsal bajo visión directa o con asistencia artroscópica, usando portales artroscópicos volares. RESULTADOS: Se operaron 488 fracturas de radio distal durante el período mencionado; 375 fracturas clasificadas como tipo C de la AO. Del total operadas, solo 392 fracturas contaban con TC peroperatoria, que permitía evaluar la presencia del FDU, el cual estuvo presente en 127/392 de los casos (32,4%). Analizados por grupo, 38 casos presentaban fragmentos tipo I, 22 tipo II, 69 tipo III y 7 tipo IV. DISCUSIÓN: El FDU se presentó en un 32,4% de los casos evaluables por TC en nuestra serie. El manejo dirigido de este fragmento con asistencia artroscópica permitió una reducción anatómica con fijación estable específica de éste. CONCLUSIÓN: Proponemos una nueva clasificación del FDU basada en la TC preoperatoria que permite realizar un adecuado plan prequirurgico y abordar este fragmento de manera específica sugiriendo cuando utilizar asistencia artroscópica.

INTRODUCTION: The dorsal-ulnar fragment (DUF) in the distal radius fracture is of special importance since it implies an alteration in the radio-carpal joint as well as in the distal radio-ulnar joint (DRUJ), where permanent joint incongruence can generate long-term sequelae. OBJECTIVE: To propose a classification of the DUF, advising when to perform arthroscopic assistance, based on a consecutive series of operated cases of distal radius fracture studied with computed tomography (CT). METHODS: Descriptive study of a series of cases of patients operated of distal radius fracture between January 2015 and December 2016. We describe a classification of the DUF and suggest a specific treatment scheme. The DUF is described as that specific fragment located in the dorso-ulnar corner of the articular surface of the distal radius, which involves more than 30% of the articular surface of the DRUJ and more than 5mm of the ulnar edge of the dorsal cortex of the radius observed in the axial section of the preoperative CT. It is considered a major fragment (FM) when the fracture compromises the Lister tubercle and is considered a minor fragment (Fm) when it does not. Our classification recognizes 4 types of DUF: type I (FM without displacement, in type C fractures of the AO); Type II (FM with displacement, in type C fractures of the AO); Type III (Fm independent of displacement, in fractures type C of the AO) and type IV (FM/Fm with displacement, in fractures type B2 of the AO). Treatment scheme: Type I: synthesis with a palmar locked plate without arthroscopic assistance required. Type II: synthesis with palmar locked plate with arthroscopic assistance. Type III dorsal percutaneous synthesis with cannulated screw with arthroscopic assistance. Type IV dorsal synthesis with plate or screw by dorsal approach under direct vision or with arthroscopic assistance using volar portals. RESULTS: A total of 488 distal radius fractures were operated during this period. Only 392 fractures had preoperative CT, which allowed to evaluate the presence of the DUF. It was present in 127/392 of the cases (32.4%). Analyzed by group, 38 cases presented fragments type I, 22 cases type II, 69 cases type III and 7 cases type IV. DISCUSSION: The DUF was presented in 32.4% of the cases in our series. The management of this fragment with arthroscopic assistance allowed an anatomical reduction with specific stable fixation of this fragment. CONCLUSION: We propose a novel classification of the DUF based on preoperative CT that allows a specific management of this fragment and suggest when to use arthroscopic assistance.

Malformación vascular capilar y venosa en la mano. Reporte de caso de una extraña patología quirúrgica / Vascular capillary and venous malformation in the hand. Case report of a strange surgical pathology

Resumen Introducción: Las anomalías vasculares representan un amplio panorama de distintas lesiones donde los tumores son los más frecuentes. Las malformaciones vasculares suelen presentarse en etapas tardías de la vida secundarias al lento crecimiento y a los síntomas que padecen los pacientes. Debe de darse un manejo multidisciplinario donde el diagnóstico es la piedra angular. Los casos de malformaciones venosas o linfáticas suelen tratarse mediante la resección de la malformación en su totalidad. Presentación del caso clínico: Varón de 35 años de edad quién presenta aumento de volumen y dolor de 3 meses de evolución en la mano derecha. A la exploración física se observa una masa en la región tenar de dicha mano, con bordes bien definidos de aproximadamente 3 × 3 cm, no móvil, adherida a planos profundos, dolorosa a palpación, con hiperestesias en trayecto del nervio mediano. Se realizaron ultrasonido Doppler y resonancia magnética, los cuales sugirieron una lesión vascular. Se realizó exploración quirúrgica y se observó una lesión vascular adherida a las estructuras nerviosa y tendinosa, las cuales se liberaron y se extrajo la tumoración. Se envió la pieza quirúrgica a patología, que reportó hemangioma capilar y venoso. Conclusiones: Las malformaciones vasculares mixtas (venoso y capilar) en la mano son una entidad poco frecuente que requiere de un manejo quirúrgico preciso. Estas lesiones generan síntomas asociados al aumento de volumen, entre los que destacan: dolor, disminución del rango de movimientos. El tratamiento quirúrgico se asocia a una mejoría de los síntomas.

Abstract Introduction: Vascular anomalies in the hand represent a rare disease that needs an accurate diagnosis and prompt surgical treatment. One of the uncommon anomalies is the mixed vascular one. The diagnosis of these malformations is clinical but radiological studies such as magnetic resonance and Doppler ultrasound are mandatory. Once the diagnosis is made, surgery is the next and final step. Recurrence is rare when the entire tumor is resected. Clinical Case Study: A 35-year-old male presented with an increase in volume and pain of three months of evolution in the right hand. On physical examination, a mass in the righthand thenar region was observed, with well-defined edges of approximately 3 x 3 cm, not mobile, adhered to deep planes, painful to palpation, with hyperesthesias in the median nerve pathway. A magnetic resonance and a Doppler ultrasound were applied showing a well-circumscribed tumor. The patient underwent surgery and the whole vascular malformation was removed with no damage of neighbor structures. Pathology reported a venous and capillary hemangioma. Conclusions: Mixed vascular malformations in the hand are uncommon pathologies that require a correct diagnosis and a prompt surgical resolution. The most frequent symptoms associated with these tumors are: tenderness, pain and limitation in the movement of the hand. Surgical treatment is always recommended.

Study Of Epidemiology Of Hand Surgery Cases In Indian Scenario

PURPOSE: -To study the epidemiology of hand surgery cases in Indian scenario. METHODS: - Retrospective study of hand surgery cases operated in the year 2015-2016 at a tertiary centre in India and the cases were further sub classified into 9 types and the age and sex distribution was estimated. RESULTS: -Atotal of 2060 cases were operated in the year 2015-2016, which were sub classified into 9 categories. Fracture fixation and tendon injuries alone constituted around 55% of cases followed by nerve affections, plastic procedures, deformity correction, tumors, congenital anomalies, miscellaneous cases and infections. Hand injuries and affections mostly inflicted socio - economic morbidity to the youngest population (up to 96% patients were <60 years) and 77.98% were males. CONCLUSION: - The study clearly underlines the importance and need of delivery of adequate hand surgery services in a developing country like India to mitigate the social and economic effects of hand affections.

Hand and wrist surgery without suspending warfarin or oral antiplatelet - systematic review / Cirurgia da mão e do punho sem suspender varfarina ou antiplaquetários orais - Revisão sistemática

ABSTRACT To assess, through a systematic literature review, whether or not it is necessary to suspend antithrombotic medications (warfarin, aspirin, and clopidogrel) to perform elective wrist and hand surgeries. The search for articles was performed using a combination of keywords in the databases available, without scientific design constraints, being selected series with five or more surgeries; the selected articles were analyzed regarding serious (need for surgical treatment) and mild complications (without surgery). Seven articles were retrieved and analyzed; 410 wrist and hand surgeries were performed in patients on warfarin or aspirin and clopidogrel, with three serious complications (0.7%) and 38 mild (9.2%); 2023 surgeries were performed in patients without use of antithrombotics, with zero serious and 18 (0.8%) minor complications. Patients using warfarin or oral antiplatelet (aspirin, clopidogrel, and aspirin associated with clopidogrel) need not suspend the medication to undergo wrist and hand surgery.

RESUMO Avaliar, por meio de revisão sistemática da literatura, se há ou não necessidade de suspender medicamentos antitrombóticos (varfarina, AAS e clopidogrel) para a realização de procedimentos eletivos de cirurgia do punho e da mão. A busca de artigos foi feita por meio da combinação de palavras-chave nas bases de dados disponíveis, sem restrições de desenho científico, sendo selecionadas séries com cinco ou mais cirurgias; os artigos selecionados foram analisados em relação às complicações graves (necessidade de tratamento cirúrgico) e leves (sem necessidade de tratamento cirúrgico). Sete artigos foram encontrados e analisados; 410 cirurgias do punho e da mão foram feitas em pacientes em uso de varfarina ou AAS e clopidogrel e observou três complicações graves (0,7%) e 38 leves (9,2%); 2.023 cirurgias foram feitas em pacientes sem uso dos antitrombóticos, apresentaram zero complicações graves e 18 leves (0,8%). Pacientes em uso de varfarina ou antiplaquetários orais (AAS, clopidogrel e AAS associado a clopidogrel) não necessitam suspender a medicação para ser submetidos a cirurgias do punho e da mão.

Rotura espontánea del tendón extensor largo del pulgar ­ transferencia tendínea con técnica anestésica WALANT / Spontaneous rupture of thumb extensor pollicis longus ­ tendon transfer under the WALANT anesthetics technique

La rotura espontanea del tendón extensor largo del pulgar (ELP), es una patología infrecuente existiendo casos reportados en la literatura donde no se logra encontrar factores predisponentes. El manejo quirúrgico suele realizarse utilizando una técnica de transposición tendínea del tendón del extensor propio del índice. En la actualidad, la técnica anestésica de WALANT "Wide Awake Local Anesthesia with No-Torniquet" ha sido de amplio desarrollo en la cirugía de la mano, sobre todo para la resolución quirúrgica de patología de tendones, con buenos y excelentes resultados. Se presenta un caso de un paciente con rotura espontánea del tendón ELP, que fue manejado con una transferencia tendínea utilizando la técnica anestésica WALANT.

The spontaneous rupture of thumb extensor pollicis longus (EPL) is a rare disease with just a few case reports known where no trigger factor has been found. The surgical management is done by the proper index extensor tendon transposition. Nowadays, the WALANT anesthetic technique ("Wide Awake Local Anesthesia with No-Torniquet") has had a broad development in hand surgery, especially in surgery for tendon injuries, with good and excellent results. A clinical case is shown with a patient who had a spontaneous EPL rupture which was managed with a tendon transfer under the WALANT anesthetics technique.

An Unusual Formation of the Superficial Palmar Arch and its Clinical Significance.

Variations of the arteries of the upper limb are an often encountered phenomenon and have been widely described in case reports and studies over the years. The superficial palmar arch (SPA) is the main source of blood supply to the palm and digits. The classical SPA is formed by an anastomosis between the superficial branches of the radial and ulnar artery, although a number of other variations have been described. Herein, we present a peculiar formation of the SPA between the superficial branch of the ulnar artery and a communicating branch from the princeps pollicis artery. We also noted an unusual origin of the radialis indicis artery from the SPA. According to the classifications of SPA variations, the observed SPA was type II or a dominant ulnar subtype of the non-arch type. The knowledge of arterial variations in the hand is important for the successful conduction of surgical and diagnostic manipulations in the hand and is therefore of interest to anatomists and clinicians.

The continuous innovation of hand surgery team rooted in clinical practice / 复旦学报（医学版）

Previously,hand-surgeons made great advancements and pioneering surgeries such as thumb reconstruction,flap transplantation surgery.Under the leadership of professor Yu-dong GU,we put forward several surgical strategies to treat the brachial plexus injury including the widely-used contralateral cervical 7 (CC7) nerve root transfer surgery.Now our department is one of the leading centers in treating peripheral nerve injury disease worldwide.During the past 10 years,we focused on the brain plasticity research in brachial plexus injury patients and revealed the reorganization pattern of sensorimotor cortex after the CC7 nerve root transfer surgery.Our study indicated the potential of one hemisphere in controlling bilateral upper limb and we further applied this conclusion in treating hemiplegic paralysis patients.In the past 10 years,we applied basic research findings in clinical practice and expanded the indication of CC7 nerve transfer surgery.By making innovations we keep making progress.

Reconstruction of hand

The characteristics of hand trauma are changing due to automation of industrial facilities, improved access to health care, and the aging population. Since the inception of hand surgery as a subspecialty, hand defects have been reconstructed with the restoration of the original functionality as the primary goal. With advancement and maturation of surgical techniques, however, restoration of aesthetics also began to take hold as an important aspect of hand surgery practice. After the first successful replantation of an amputated digit, the rapid development of microsurgical techniques had a significant impact on the field of reconstructive hand surgery. In the first two decades, the success of replantation was evaluated by the survival rate for a single operator or a specialized institution. These days, however, microsurgical techniques have been widely adopted, with digital replantation possible even for infants. In addition to various local flaps, the evolution of free flaps has vastly expanded the repertoire of reconstructive options for hand surgeons. With the wide variety of free flaps available, it is possible for a severely injured hand to be salvaged and restored to its original functional and aesthetic status. In South Korea, hand surgery is becoming an established profession with a separate subspecialty certification. Hand surgery has a bright outlook, with future research directed at new biocompatible materials and novel reconstructive methods.

Factors Associated with Postoperative Nausea and Vomiting in Patients Undergoing an Ambulatory Hand Surgery

BACKGROUND: Patients undergoing ambulatory surgery under general anesthesia experience considerable levels of postoperative nausea and vomiting (N/V) after their discharge. However, those complications have not been thoroughly investigated in hand surgery patients yet. We investigated factors associated with postoperative N/V in patients undergoing an ambulatory hand surgery under general anesthesia and determined whether patients' satisfaction with this setting is associated with postoperative N/V levels. METHODS: We prospectively evaluated 200 consecutive patients who underwent ambulatory hand surgeries under general anesthesia to assess their postoperative N/V visual analogue scale (VAS) levels during the first 24 hours after surgery and their satisfaction with an ambulatory surgery setting. Potential predictors of postoperative N/V were; age, sex, body mass index, smoking behavior, a history of postoperative N/V after previous anesthesia or motion sickness, preoperative anxiety level and the duration time of anesthesia. We conducted multivariate analyses to identify factors associated with postoperative N/V levels. We also conducted multivariate logistic regression analyses to determine whether the N/V levels are associated with the patients' satisfaction with this setting. Here, potential predictors for satisfaction were sex, age, postoperative pain and N/V. RESULTS: Postoperative N/V were associated with a non-smoking history, a history of motion sickness and a high level of preoperative anxiety. Twenty-two patients (11%) were dissatisfied with the ambulatory setting and this dissatisfaction was independently associated with moderate (VAS 4-7) and high (VAS 8-10) levels of postoperative N/V and with a high level (VAS 8-10) of postoperative pain. CONCLUSIONS: Although most of the patients were satisfied with the ambulatory surgery setting, moderate to high levels of N/V were associated with dissatisfaction of patients with this setting, suggesting a need for better identifying and managing those patients at risk. The information regarding risk factors for N/V could help in preoperative patient consultation regarding an ambulatory hand surgery under general anesthesia.

Psychological Issue in Hand Trauma

Acquired hand trauma is a significant event that often affects an individuals’ life in diverse manners. The present paper aims to review the psychological issues in hand trauma along with factors that affect recovery from the same. Method: A relevant search for literature on psychological issues in hand trauma was made across search engines like Google Scholar, Medline and Pubmed and relevant studies were selected for this review. The studies include those on symptomatology, course as well as treatment. The studies were analyzed critically along with inputs of personal clinical experience of the authors. Results: Psychological symptoms that occur after hand trauma together with the treatment methods that provide relief from psychological symptoms are discussed. Symptoms of post-traumatic stress disorder (PTSD), flashbacks, concerns with personal appearance, avoidance of reminders of the trauma and physiological arousal along with sleep issues have been discussed. The article also looks at the psychosocial effects of hand trauma including marital and sexual issues that may arise. Treatment interventions commonly used in the form of imagery and in vivo exposure with and without cognitive restructuring are explained along with psychoeducation approaches that may benefit these patients. Conclusions: It is important that surgeons and professionals dealing with hand trauma are aware of the psychological issues in hand trauma and to take appropriate steps to deal with any such problems that ensue.

Present and future of hand surgery in Korea

The purpose of this article is to review the past history of hand surgery briefly and to overview of a vision of hand surgery over next generations in republic of Korea. There were three characteristics of the past history of digit replantation in Korea. Due to the tremendous use of press machine, the replantation surgery for finger amputation had been developed rapidly from 1980's to 1990's period. Also new microsurgery techniques had been introduced such as toe pulp free flap for digit reconstruction. These techniques had been developed based on the medical health insurance system for the factory employees. Future of hand surgery in Korea can be anticipated as followings: operative microscopy and robotics may help surgeons to anastomosis very tiny micro-vessels; the functional recovery of fingers and hands will be more important; incidence of degenerative disease, musculoskeletal system disorder due to excessive use and injury during sports will increase; new materials such as artificial joint will be used more frequently according to the innovation of tissue engineering and regenerative medicine; specialist system for hand surgeon will be settled. Since there are a lot of hand surgeon who has a mission to alleviate patient's pain and injury, there will be a continuous growth of hand surgery in Korea.
