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.

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.

Onset of Trigger Finger after Carpal Tunnel Syndrome Surgery: Assessment of Open and Endoscopic Techniques / Frequência do aparecimento de dedo em gatilho no pós-operatório da síndrome do túnel do carpo em duas técnicas cirúrgicas: Aberta e endoscópica

Abstract Objective The present study aimed to determine the frequency of trigger finger (TF) onset after surgery for carpal tunnel syndrome (CTS) using an open (OT) or an endoscopic technique (ET). As a secondary endpoint, the present study also compared paresthesia remission and residual pain rates in patients submitted to both techniques. Methods Trigger finger onset and remission rates of paresthesia and pain at the median nerve territory was verified prospectively in a series of adult patients submitted to an OT procedure (n = 34). These findings were compared with a retrospective cohort submitted to ET (n = 33) by the same surgical team. Patients were evaluated with a structured questionnaire in a return visit at least 6 months after surgery. Results Sixty-seven patients were evaluated. There was no difference regarding trigger finger onset (OT, 26.5% versus ET, 27.3%; p = 0.94) and pain (OT, 76.5% versus ET, 84.8%; p = 0.38). Patients submitted to OT had fewer paresthesia complaints compared with those operated using ET (OT, 5.9% versus ET, 24.2%; p = 0.03). Conclusions In our series, the surgical technique did not influence trigger finger onset and residual pain rates. Patients submitted to OT had less complaints of residual postoperative paresthesia.

Resumo Objetivo Determinar a frequência do aparecimento de dedo em gatilho (DG) no pós-operatório da síndrome do túnel do carpo (STC) em duas técnicas: aberta (TA) e endoscópica (TE). Como desfecho secundário, comparar as taxas de remissão da parestesia e dor residual entre as duas técnicas. Métodos De forma prospectiva, verificamos o aparecimento de dedo em gatilho e taxa de remissão da parestesia e dor no território do nervo mediano em série de pacientes adultos operados pela TA (n = 34). Comparamos com coorte retrospectiva operada pela TE (n = 33), pela mesma equipe de cirurgiões. A avaliação dos pacientes ocorreu por meio de questionário estruturado em consulta de retorno, com mínimo de 6 meses de pós-operatório. Resultados Sessenta e sete pacientes foram avaliados. Não houve diferença quanto ao aparecimento de dedo em gatilho (TA, 26,5% versus TE, 27,3%; p = 0,94) e dor (TA, 76,5% versus TE, 84.8%; p = 0,38). Os pacientes operados pela TA apresentaram menos queixas de parestesia do que os operados pela TE (TA 5,9% versus TE 24,2%; p = 0,03). Conclusões Em nossa série, a técnica cirúrgica não influenciou o aparecimento de dedos em gatilho e dor residual. Os pacientes operados pela técnica aberta apresentaram menos queixa de parestesia residual pós-operatória.

Diagnosis and Treatment of Trigger Finger in Brazil - A Cross-Sectional Study / Diagnóstico e tratamento do dedo de gatilho no Brasil - Estudo transversal

Abstract Objective The present paper aims to evaluate the therapeutic planning for trigger finger by Brazilian orthopedists. Methods This is a cross-sectional study with a population composed of participants from the 2018 Brazilian Congress on Orthopedics and Traumatology (CBOT-2018, in the Portuguese acronym), who answered a questionnaire about the conduct adopted for trigger finger diagnosis and treatment. Results A total of 243 participants were analyzed, with an average age of 37.46 years old; most participants were male (88%), with at least 1 year of experience (55.6%) and from Southeast Brazil (68.3%). Questionnaire analysis revealed a consensus on the following issues: diagnosis based on physical examination alone (73.3%), use of the Quinnell classification modified by Green (58.4%), initial nonsurgical treatment (91.4%), infiltration of steroids combined with an anesthetic agent (61.7%), nonsurgical treatment time ranging from 1 to 3 months (52.3%), surgical treatment using the open approach (84.4%), mainly the transverse open approach (51%), triggering recurrence as the main nonsurgical complication (58%), and open surgery success in > 90% of the cases (63%), with healing intercurrences (54%) as the main complication. There was no consensus on the remaining variables. Orthopedists with different practicing times disagree on treatment duration (p = 0.013) and on the complication rate of open surgery (p = 0.010). Conclusions Brazilian orthopedists prefer to diagnose trigger finger with physical examination alone, to classify it according to the Quinnell method modified by Green, to institute an initial nonsurgical treatment, to perform infiltrations with steroids and local anesthetic agents, to sustain the nonsurgical treatment for 1 to 3 months, and to perform the surgical treatment using a transverse open approach; in addition, they state that the main nonsurgical complication was triggering recurrence, and report open surgery success in > 90% of the cases, with healing intercurrences as the main complication.

Sem consenso nas demais variáveis. De acordo com a experiência, foram observadas diferenças referentes ao tempo de tratamento (p = 0.013) e a taxa de complicação da cirurgia aberta (p = 0.010). Conclusões O ortopedista brasileiro tem preferência pelo diagnóstico do dedo em gatilho apenas com exame físico, classifica segundo Quinnell modificado por Green, tratamento inicial não cirúrgico, infiltrações com corticoide e anestésico local, tempo de tratamento não cirúrgico de 1 a 3 meses, tratamento cirúrgico por via aberta transversa, principal complicação não cirúrgica a recidiva do engatilhamento, e considera o sucesso da cirurgia aberta em > 90% dos casos, tendo como principal complicação as complicações cicatriciais.

Randomized Controlled Trial on Combined Percutaneous Release and Steroid Injection Versus Percutaneous Release Alone for Trigger Finger in Adults

@#INTRODUCTION: Trigger finger is one of the most common causes of hand pain and disability. Surgical treatment consists of release of the A-1 pulley by open or percutaneous techniques. Many authors have noted that percutaneous release is convenient and cost-effective with a low complication rate. Only few studies have published results on combination of percutaneous release and steroid injection. OBJECTIVE: To compare the differences of outcomes in adults with trigger finger treated with combination of percutaneous release and corticosteroid injection to those treated with percutaneous release alone METHODS: We included all patients older than 18 years old in the UP-PGH Department of Orthopedics with a diagnosis of trigger finger who have consented to participate in this study. They were randomized into two treatment groups. One group was treated with percutaneous release only and the other group was treated with combined percutaneous release and corticosteroid injection. Outcomes measured were total active motion (TAM), postoperative pain, time to return-to-work, patient satisfaction, and complications. RESULTS: Post-procedure, both groups showed significant improvement in motion of the fingers (p = 0.034) and pain relief (p = 0.001). TAM scores of the combination group were better compared to the control at all time intervals (p = 0.03, 0.008, 0.004, 0.019) and better pain VAS scores in the 1st week (p = 0.009). Patients who received the combination treatment showed a trend toward better patient satisfaction, shorter duration of post-release pain and earlier return-to-work. CONCLUSION: significantly improves TAM and pain VAS scores.

Tenosinovitis estenosante de tendones flexores de la mano: revisión de la literatura / Stenosing flexor tenosynovitis of the hand: literature review

Flexor tendon tenosynovitis is an entrapment of the flexor tendons at its entrance to the pulley system. Because there is a high incidence of this pathology, it should be well known by physicians, rheumathologists and orthopaedic surgeons. On this paper we present a literature review, analyzing the anatomic facts, biomechanics, diagnosis, classification, therapeutic options and we propose some general recommendations for physicians.

Evaluación de resultados clínicos postoperatorios a corto y largo plazo de liberación percutánea con aguja vs técnica abierta de dedo en gatillo / Evaluation of postoperative results short and long term of percutaneous liberation vs open technique for trigger finger

Resumen: Introducción: El dedo en gatillo es muy frecuente en la población, con un riesgo de vida de padecer la enfermedad de 2.6% en la población general y con un aumento de 4 a 10% en diabéticos. Dado que no hay un estándar de oro de tratamiento quirúrgico y aún hay controversia en ello, es importante evaluar los resultados de las distintas técnicas quirúrgicas. El objetivo de este estudio es evaluar resultados postoperatorios de ambas técnicas quirúrgicas en pacientes con seguimiento de uno a 12 meses de postoperatorio. Material y métodos: Se trata de un estudio prospectivo, longitudinal, descriptivo y observacional realizado en un período de Enero de 2015 a Diciembre de 2017. Se incluyeron pacientes postoperados de liberación con técnica abierta (grupo 1) y percutánea con aguja (grupo 2). Se llevó a cabo la revisión de expedientes de todos los pacientes y se les hizo una encuesta mediante vía telefónica. Los resultados de la comparación de ambas técnicas se analizaron mediante χ2 para resultados paramétricos y mediante la prueba de Fisher para los no paramétricos. Resultados: Se encontró que los pacientes del grupo 2 manifestaron mayor satisfacción, de los cuales 21.8% (n = 12) estuvieron totalmente satisfechos con el procedimiento percutáneo, a diferencia de los del grupo 1 quienes manifestaron satisfacción total sólo en 3.8% (n = 2). Conclusiones: En este estudio podemos concluir que ambas técnicas son efectivas para el tratamiento de dedo en gatillo, siendo la liberación percutánea con aguja la que ofrece mayor grado de satisfacción en los pacientes.

Abstract: Indroduction: Trigger finger is very common in the population, with a life-threatening risk of developing the disease of 2.6% in the general population and increasing to 4 to 10% in diabetics. Since there is no standard gold of surgical treatment and there is still controversy in this, it is important to evaluate the results of the different surgical techniques. The objective of this study is to evaluate postoperative results of both surgical techniques in patients with follow-up of 1 to 12 months postoperative. Material and methods: It is a prospective, longitudinal, descriptive and observational study carried out in a period from January 2015 to December 2017. Postoperative open (group 1) and percutaneous needle (group 2) patients were included. All patients were reviewed and surveyed by telephone. The comparison results of both techniques were analyzed using χ2 for parametric results and by the Fisher test for nonparametric results. Results: It was found that patients in group 2 expressed greater satisfaction, where 21.8% (n = 12) were fully satisfied with the percutaneous procedure, unlike those in group 1 where total satisfaction was only manifested at 3.8% (n = 2). Conclusions: In this study we can conclude that both techniques are effective for the treatment of trigger finger, with percutaneous needle release offering the highest degree of satisfaction in patients.

CONCLUSIONS: the application the Modified Duran protocol as immediate rehabilitation in patients with flexor tendon injuries of the hand is more effective than conventional rehabilitation treatment being a tool that can be applied early in patients after surgery for this injury

Hamstring Tendon Autograft Contamination in Anterior Cruciate Ligament Reconstruction: Comparison between two Harvesting Techniques / Contaminação de enxertos de tendões flexores na reconstrução do ligamento cruzado anterior: comparação de duas técnicas de retirada

Abstract Objective: To evaluate the contamination rate of hamstring tendon autografts by comparing two different techniques, and to verify whether intraoperative contamination is associated with the development of clinical infection in patients submitted to reconstruction of the anterior cruciate ligament (ACL). Methods: A total of 110 hamstring tendon autograft ACL reconstructions were performed and divided into two groups: 1-hamstring tendon retraction technique; and 2 - technique maintaining the tibial insertion of the hamstring tendon. During the preparation, two graft fragments were sent for culturing; the harvesting time, the preparation time, and the total surgery time were measured. Twenty-four hours after the surgery, the C-reactive protein was assayed. The clinical outpatient follow-up was performed up to 180 days postoperatively. Results: Although there were two postoperative infections, there was no graft contamination or difference between the groups in relation to the graft preparation time and to the 24-hour postoperative C-reactive protein assessment. The classic technique presented a longer graft harvesting time (p = 0.038), and there was no statistical difference between the 2 groups regarding the degree of contamination and consequent clinical infection, although 2 patients in group 2 presented with infection, with negative perioperative cultures. Conclusion: Based on the results obtained, there was no association between graft contamination and the time or technique of its preparation. In addition, there was also no association between intraoperative contamination and the development of clinical infection, nor was there any sign of an association between the early alteration of Creactive protein and the onset of infection.

Resumo Objetivo: Avaliar a taxa de contaminação de autoenxerto de tendões flexores comparando duas técnicas e verificar se a contaminação intraoperatória está associada ao desenvolvimento de infecção clínica em pacientes submetidos a reconstrução do ligamento cruzado anterior. Métodos: Foram feitas 110 reconstruções do ligamento cruzado anterior com tendão dos flexores e divididas em dois grupos: 1) técnica com retirada total dos tendões flexores e 2) técnica que manteve a inserção tibial desses tendões. Durante o preparo, dois fragmentos de cada um desses foram enviados para cultura, sendo mensurado o tempo de retirada dos tendões, do preparo dos tendões e total da cirurgia. Com 24 horas de pós-operatório, foi dosada a proteína C reativa. Seguimento clínico ambulatorial foi realizado de forma protocolada até 180 dias de pós-operatório. Resultados: Apesar de terem sido observadas duas infecções pós-operatórias, não houve contaminação dos enxertos nem diferença entre os grupos emrelação ao tempo de preparo dos enxertos e a proteína C reativa com 24 horas de pós-operatório. A técnica clássica apresentou maior tempo de retirada do enxerto (p = 0,038) e não houve diferença estatística entre os dois grupos no que tange ao grau de contaminação e consequente infecção clínica, embora dois pacientes do grupo 2 tenham tido infecção com culturas perioperatórias negativas. Conclusão: Com base nos resultados obtidos, não houve associação entre contaminação do enxerto com o tempo ou a técnica de sua preparação, tampouco entre a contaminação intraoperatória e o desenvolvimento de infecção clínica ou entre alteração precoce da proteína C reativa e o surgimento de infecção.

Ultrasound-guided selective nerve blocks for trigger finger surgeries to maintain flexion/extension of fingers - Case series / Bloqueios seletivos guiados por ultrassom para cirurgias de dedo em gatilho para manutenção da flexão/extensão dos dedos - Série de casos

Abstract Background: A patient's ability to move his/her fingers during hand surgery may be helpful to surgeons because it allows the effectiveness of the intervention evaluation and prediction of hand function in the postoperative period. The purpose of this case series is to demonstrate the efficacy of an ultrasound-guided peripheral nerve block technique to maintain the hand flexor and extensor muscles motor function and discuss the benefits of the technique for trigger finger surgery. Case report: Ten patients scheduled to undergo trigger finger surgery were selected. The goal was to maintain flexion and extension of the fingers during the procedure. Thus, ultrasound-guided ulnar, radial, and medial nerve block was performed in the distal third of the forearm, at 5-7 cm proximal to the wrist. The block was performed with 5 mL of 0.375% bupivacaine on each nerve. All procedures were uneventfully performed maintaining the flexion and extension of the fingers. In two cases, it was observed that the motricity maintenance and the patients' ability to move their fingers when requested allowed the success of the surgical procedure after the third intraoperative evaluation. Conclusion: This case series shows that it is possible to maintain the motor function of the hand flexor and extensor muscles to perform finger trigger surgeries using specific ultrasound-guided distal blocks.

Resumo Justificativa: A capacidade de um paciente mover os dedos durante a cirurgia da mão pode ser útil para o cirurgião porque permite a avaliação da eficácia da intervenção e a predição da função da mão no pós-operatório. O objetivo desta série de casos é demonstrar a eficácia de uma técnica de bloqueio de nervo periférico guiado por ultrassom na manutenção da função motora dos músculos flexores e extensores da mão e discutir os benefícios da técnica para cirurgias de liberação de dedo em gatilho. Relato de caso: Foram selecionados 10 pacientes em programação para cirurgia de liberação de dedo em gatilho. O objetivo era manter a flexão e a extensão dos dedos durante o procedimento. Dessa forma, o bloqueio dos nervos ulnar, radial e mediano, guiados por ultrassom, foi feito no terço distal do antebraço, 5 a 7 cm proximais ao punho. O bloqueio foi feito com 5 mL de bupivacaína a 0,375% em cada nervo. Todos os procedimentos foram feitos sem complicações e com manutenção da flexão e extensão dos dedos. Em dois casos, observou-se que a manutenção da motricidade e a capacidade dos pacientes de mover os dedos quando solicitado permitiu o sucesso do procedimento cirúrgico após a terceira avaliação intraoperatória. Conclusão: Esta série de casos mostra que é possível manter a função motora dos músculos flexores e extensores da mão em cirurgias de liberação de dedo em gatilho por meio de bloqueios distais específicos guiados por ultrassom.

OBJECTIVE@#To explore the efficacy of ultrasound-guided needle-knife with precise three-dimensional stereotactic localization of points for stenosing tenosynovitis of flexor tendon (trigger finger).@*METHODS@#A total of 74 patients were randomly divided into an observation group and a control group, 37 cases in each group. The patients in the observation group were treated with ultrasound-guided intrathecal injection and releasing method of needle-knife, while the patients in the control group were treated with ultrasound-guided intrathecal injection. The self-made 9-score scale of trigger finger was recorded before treatment, immediately after treatment, 1 month and 3 months after treatment; the curative effect of the two groups was evaluated.@*RESULTS@#The results of self-made 9-score scale in the observation group immediately after treatment, 1 month and 3 months after treatment were lower than that before treatment (all <0.01); the scores in the observation group were lower than those in the control group at each time point after treatment (all <0.01). The excellent and good rate immediately after treatment was 100.0% (37/37) in the observation group, which was superior to 8.1% (3/37) in the control group (<0.05); the cured rates in the observation group were 100.0% (37/37) 1 month after treatment and 97.3% (36/37) 3 months after treatment, which were superior to 13.5% (5/37) and 10.8% (4/37) in the control group, respectively (<0.05).@*CONCLUSION@#The needle-knife with three-dimensional stereotaxic location of point could significantly improve the symptoms of trigger finger, with superior immediate and long-term efficacy.

Morphometric study of pulleys of the thumb / 대한해부학회지

Pulleys are thickened regions in flexor tendons sheaths of the digits. They are essential and act as fulcrum for the flexion and extension of the digits. The arrangement and number of pulley system differs greatly between the thumb and other digits. There is paucity of literature regarding the pulley system of thumb. We aimed to study the morphometry of the pulley system of the thumb in Indian cadavers. Dissection was carried out in 55 adult human cadaveric thumbs. The most common morphologic pattern of pulley observed in the thumb is type III (30 thumbs). The least observed is type I (4 thumbs). The mean width and standard deviation of A1, Av, oblique, and A2 pulleys are 5.06±0.87, 5.38±1.22, 4.68±1.13, and 6.04±1.41 mm, respectively. The gap distances between the pulleys were also measured. The results obtained from the present study may be helpful in surgical treatment of trigger thumb with less complication and also in reconstruction of the closed rupture of the pulley of the thumb.

Morphological alterations of the tendon and pulley on ultrasound after intrasynovial injection of betamethasone for trigger digit

PURPOSE: The aim of this study was to elucidate whether intrasynovial corticosteroid injections for trigger digit reduced the volume of the tendon and pulley on high-resolution ultrasonography. METHODS: Twenty-three digits of 20 patients with trigger digit were included. Each affected finger was graded clinically according to the following classification: grade I for pre-triggering, grade II for active triggering, grade III for passive triggering, and grade IV for presence of contracture. Axial ultrasound examinations were performed before an intrasynovial corticosteroid injection and at an average of 31 days after the injection. The transverse diameter, thickness, and cross-sectional area of the tendon and the thickness of the pulley were measured by two independent, blinded researchers. RESULTS: At least 1 grade of improvement was achieved in this study group by the time of the second examination. The transverse diameter and cross-sectional area of the tendon and the thickness of the pulley significantly decreased (P < 0.05). CONCLUSION: The injection of a single dose of betamethasone improved clinical symptoms by reducing the volume of both the tendon and pulley, which may be related to the fact that tendon and pulley ruptures are delayed by corticosteroid injections.

Ultrasound-Guided Percutaneous Release of the Trigger Thumb

PURPOSE: Trigger thumb is a common condition with a prevalence rate up to 3% among the adults. The main pathophysiology is locking of the flexor tendon at the A1 pulley. Treatments include nonsteroidal anti-inflammatory drug, steroid injection, and surgical A1 pulley release. The purpose of this study was to evaluate the safety and effectiveness of ultrasound-guided percutaneous release of trigger thumb. METHODS: The author prospectively reviewed 37 patients who had undergone ultrasound-guided percutaneous release by the same surgeon from January 2012 to June 2014. The effect of ultrasound-guided A1 pulley release was evaluated by using visual analogue scale (VAS) score, disabilities of arm, shoulder, and hand (DASH) score, and grip and pinch strengths preoperatively and at 12weeks after the surgery. In addition, complications related with the procedure were evaluated. RESULTS: Triggering and locking were resolved in all patients after surgery. VAS and DASH improved from 5.0±1.8 and 45.8±16.9 preoperatively to 0.3±0.6 and 16.2±6.3 at 12 weeks, respectively (p=0.019 and p=0.021). Grip and pinch strengths statistically improved from33.5±8.6 kg and 36.7±8.1 kg, preoperatively 46.2±6.1 kg and 47.1±7.4 kg, respectively (p=0.026 and p=0.041). Complications such as incomplete resection, neurologic symptoms or wound infection were not found throughout the period of the study. CONCLUSION: Ultrasound-guided percutaneous A1 pulley release provides complete relief of symptoms with no major complication in trigger thumb.

Ibuprofen timing for hand surgery in ambulatory care

OBJECTIVE: To evaluate the effect of pre-operative administration of ibuprofen on post-operative pain control vs. early post-operative administration for hand surgery procedures performed under local anaesthesia in ambulatory care. METHODS: Candidates to trigger finger release by De Quervain tenosynovitis and carpal tunnel operation under local anesthesia were enrolled in the study. Group A received 400 mg ibuprofen before the operation and placebo after the procedure; group B received placebo before the operation and ibuprofen 400 mg at the end of the procedure; both groups received ibuprofen 400 mg every 6h thereafter. Visual analogue scale (VAS) was measured at fixed times before and every 6h after surgery, for a total follow-up of 18h. RESULTS: Groups were similar according to age, gender and type of surgery. Median VAS values did not produce any statistical significance, while there was a statistically significant difference on pre-operative and early post-operative VAS values between groups (A -8.53 mm vs. B 3.36 mm, p=0.0085). CONCLUSION: Average pain levels were well controlled by local anesthesia and post-operative ibuprofen analgesia. Pre-operative ibuprofen administration can contribute to improve early pain management. Level of Evidence II, Therapeutic Studies.

Complex Regional Pain Syndrome Following Percutaneous Trigger Thumb Release / 대한정형외과학회잡지

Trigger finger is one of the most common causes of hand pain and disability. Persistent trigger finger after conservative treatment has been managed with surgical release of the A1 pulley. Percutaneous A1 pulley release is being increasingly performed and many authors have reported comparable outcomes with open surgical release. However, complications have been reported, including incomplete release, flexor tendon injury, and neurovascular injury due to the blind nature of the procedure. We report on a case of a 49-year-old female who presented with features of a type I complex regional pain syndrome (CRPS) following percutaneous A1 pulley release. CRPS is a relatively common complication occurring after trauma and surgical procedures of the upper extremities. We experienced a case of CRPS following percutaneous A1 pulley release which was treated effectively following early diagnosis and through a multidisciplinary approach including physical therapy and medication.

On the variations of the muscle flexor digitorum brevis: anatomical insight / Variaciones del músculo flexor corto de los dedos: experiencias de anatomía

Flexor digitorum brevis, an intrinsic muscle of the sole of the foot, is stated as one of the muscles that shows frequent anatomical variations. Its most commonly reported anomaly is the absence of tendon to the little toe. From a clinical standpoint of view, flexor digitorum brevis musculocutanous flap is used in the reconstruction of the heel pad and flexor digitorum brevis tendon transfer is employed in the correction of flexible claw and hammer toe deformities. Despite its significance little is known regarding the variations of this muscle in Sri Lankans. Hence, the goal of this study was to elucidate the incidence and morphological features of this muscle in an adult Sri Lankan population. A total of one hundred and thirty five apparently healthy human feet were dissected and studied for the morphological features of the flexor digitorum brevis muscle. The incidence of the absent fourth tendon of the flexor digitorum brevis in the present study was found to be 71.85 percent. In all cases, when absent, it was missing bilaterally. The results of the present study further highlight the anatomical variations of the flexor digitorum brevis muscle. A sound knowledge about the anatomical variations of flexor digitorum brevis will facilitate the outcome of surgical as well as diagnostic imaging techniques of the foot. Furthermore, understanding muscle architecture of the foot may assist in the design of prosthesis and analysis of foot function.

El músculo flexor corto de los dedos, es un músculo intrínseco de la planta del pie que frecuentemente presenta variaciones anatómicas. La variación más frecuente es la ausencia de tendón destinado al dedo mínimo. Desde el punto de vista clínico se utilizan colgajos musculocutáneos del músculo flexor corto de los dedos para la reconstrucción de la región subcalcánea. Además, el tendón del músculo es usado para corregir deformidades de garra y martillo de los dedos del pie. A pesar de su importancia, es escasa la información acerca de este músculo en la población adulta de Sri Lanka.Fueron disecados 135 pies humanos aparentemente sanos analizándose sus características morfológicas. Se determinó que un 71,85 por ciento el tendón para el quinto dedo del músculo flexor corto de los dedos estaba ausente. En todos los casos, ésta se presentaba bilateralmente. El estudio señala la importancia de tener un cabal conocimiento acerca de las variaciones anatómicas del músculo flexor corto de los dedos, para facilitar tanto las técnicas quirúrgicas, como el diagnostico a través de imagenlogía del pie. Además, un buen conocimiento de la arquitectura muscular del pie puede ayudar en el diseño de prótesis y en el análisis de la función del pie.

Em 10 polegares o resultado foi satisfatório (77%), sendo que oito foram diagnosticados até a idade de 24 meses. O tempo médio do diagnóstico até a melhora foi de 20,8 meses (limites de seis a 36 meses). Os três polegares que necessitaram de tratamento cirúrgico tiveram seu diagnóstico após a idade de dois anos e meio. CONCLUSÕES: O tratamento conservador do polegar em gatilho na criança apresenta alto índice de sucesso, especialmente nas crianças que têm seu diagnóstico antes da idade de dois anos. Esta é uma informação importante a ser transmitida aos pais e que pode evitar cirurgia desnecessária em muitos casos.

OBJECTIVE: The aim of this study was to evaluate the outcome of conservative treatment of trigger thumb in children, in order to discuss the real need for surgical release in these patients. METHODS: This was a retrospective study on a group of children with trigger thumb who were treated conservatively by the same orthopedic surgeon with gentle manipulation at the time of the consultation and guidance on stretching to be performed at home. The cases were followed up for at least five years. RESULTS: Thirteen thumbs in 11 children (seven boys and four girls) were treated. The mean age at the first consultation was 26.3 months (range: 11 to 36 months). The mean follow-up was 10 years (range: 5 to 16 years). Ten thumbs showed satisfactory results (77%): eight of these were diagnosed when the child was younger than two years of age. The mean time taken from diagnosis to clinical improvement was 20.8 months (range: 6 to 36 months). The three thumbs that required surgical treatment were diagnosed after the age of two years and six months. CONCLUSIONS: Conservative treatment of trigger thumb in children showed a high rate of success, especially in children who were diagnosed up to the age of two years. This is important information to be passed on to parents and may avoid unnecessary surgery in many cases.

The Efficacy of Steroid Injection in the Treatment of Trigger Finger

BACKGROUND: Trigger finger is one of the most common reasons for referral to a hand specialist clinic. The purpose of this study is to investigate the efficacy of steroid injections for treating trigger digits. METHODS: Ninety digits were investigated with at least a year follow up. The study mainly focused on the efficacy of the injections, as well as co-morbidities, presence of a nodule, actual digit injected and the severity at presentation using Green's classification. RESULTS: The study found that 66% of trigger digits were effectively treated using steroid injections. There was a difference between the efficacy of the injection in the different digits, with a statistical significance between the thumb and the fingers. The results also showed that there was no statistical relationship between the severity of the condition, the presence of a nodule or co-morbidities and the efficacy of the steroid injections. CONCLUSIONS: The study found that steroid injections are an effective first-line intervention for the treatment of trigger digit. It also found an increased efficacy for treating the thumb compared to other digits. Both the severity of the condition at presentation and the presence of a nodule had no significant impact on the efficacy of the injections.
