Distal Radial Fractures with Scaphoid Fractures.

Objective This study evaluated the epidemiological data and functional outcomes from patients with concomitant distal radial and scaphoid fractures treated in a single center specialized in hand surgery. Functional outcomes analysis used validated instruments. Methods Patients diagnosed with distal radial and scaphoid fractures treated from January 2011 to December 2021 underwent assessments using the Disabilities of the Arm, Shoulder and Hand (DASH), Patient-Rated Wrist Evaluation (PRWE), Visual Analog Scale (VAS) for pain, goniometry, radiographic consolidation, and complications six months after surgery. Results The study included 23 patients, 73.9% men and 26.1% women. Most (56.5%) fractures occurred on the right side, and 43.5% happened on the left side. Treatment of most (56%) distal radial fractures used a locked volar plate. Functional assessment by PRWE resulted in a mean score of 35.9 points (range, 14 to 71 points), while DASH showed a mean score of 37.8 points (range, 12 to 78 points). The mean VAS was 2.33 during activities (range, 0.6 to 6.2). Conclusion Distal radial fractures associated with scaphoid fractures resulted from high-energy trauma, and most patients were males. There was a low rate of complications with surgical treatment, and the patients had satisfactory functional evolution with a low level of pain.

Diagnostic criteria and outcome measures in randomized clinical trials on carpal tunnel syndrome: a systematic review.

BACKGROUND: The diagnostic criteria for carpal tunnel syndrome (CTS) lack uniformity. Moreover, because CTS is a syndrome, there is no consensus as to which signs, symptoms, clinical and complementary tests are more reproducible and accurate for use in clinical research. This heterogeneity is reflected in clinical practice. Thus, establishing effective and comparable care protocols is difficult. OBJECTIVE: To identify the diagnostic criteria and outcome measures used in randomized clinical trials (RCTs) on CTS. DESING AND SETTING: Systematic review of randomized clinical trials carried out at the Federal University of São Paulo, São Paulo, Brazil. METHODS: We searched the Cochrane Library, PubMed, and Embase databases for RCTs with surgical intervention for CTS published between 2006 and 2019. Two investigators independently extracted relevant data on diagnosis and outcomes used in these studies. RESULTS: We identified 582 studies and 35 were systematically reviewed. The symptoms, paresthesia in the median nerve territory, nocturnal paresthesia, and special tests were the most widely used clinical diagnostic criteria. The most frequently assessed outcomes were symptoms of paresthesia in the median nerve territory and nocturnal paresthesia. CONCLUSION: The diagnostic criteria and outcome measures used in RCTs about CTS are heterogeneous, rendering comparison of studies difficult. Most studies use unstructured clinical criteria associated with ENMG for diagnosis. The Boston Questionnaire is the most frequently used main instrument to measure outcomes.

Quality analysis of prior systematic reviews of carpal tunnel syndrome: an overview of the literature

ABSTRACT BACKGROUND: Carpal tunnel syndrome (CTS) is a common condition greatly affects patients' quality of life and ability to work. Systematic reviews provide useful information for treatment and health decisions. OBJECTIVE: This study aimed to assess the methodological quality of previously published systematic reviews on the treatment of CTS. DESIGN AND SETTING: Overview of systematic reviews conducted at the Brazilian public higher education institution, São Paulo, Brazil METHODS: We searched the MEDLINE and Cochrane Library database for systematic reviews investigating the treatment of CTS in adults. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and measurement tool to assess systematic reviews (AMSTAR) were applied by two independent examiners. RESULTS: Fifty-five studies were included. Considering the stratification within the AMSTAR measurement tool, we found that more than 76% of the analyzed studies were "low" or "very low". PRISMA scores were higher when meta-analysis was present (15.61 versus 10.40; P = 0.008), while AMSTAR scores were higher when studies performed meta-analysis (8.43 versus 5.59; P = 0.009) or when they included randomized controlled trials (7.95 versus 6.06; P = 0.043). The intra-observer correlation demonstrated perfect agreement (> 0.8), a Spearman's correlation coefficient of 0.829, and an ICC of0.857. The inter-observer correlation indicated that AMSTAR was more reliable than PRISMA. CONCLUSION: Overall, systematic reviews of the treatment of CTS are of poor quality. Reviews with better-quality conducted meta-analysis and included randomized controlled trials. AMSTAR is a better tool than PRISMA because it has a better performance and should be recommended in future studies.

Hydroxychloroquine for treatment of COVID-19 patients: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: We performed a systematic review of the literature and meta-analysis on the efficacy and safety of hydroxychloroquine to treat COVID-19 patients. METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and LILACS (January 2019 to March 2021) for patients aged 18 years or older, who had COVID-19 and were treated with hydroxychloroquine versus placebo or standard of care. We also searched the WHO Clinical Trials Registry for ongoing and recently completed studies, and the reference lists of selected articles and reviews for possible relevant studies, with no restrictions regarding language or publication status. Random-effects models were used to obtain pooled mean differences of treatment effect on mortality, and serious adverse effects between hydroxychloroquine and the Control Group (standard of care or placebo); heterogeneity was assessed using the I2 and the Cochran´s Q statistic. RESULTS: Nine studies met the inclusion criteria and were included in the meta-analysis. There was no significant difference in mortality rate between patients treated with hydroxychloroquine compared to standard of care or placebo (16.7% versus 18.5%; pooled risk ratio 1.09; 95% confidence interval: 0.99-1.19). Also, the rate of serious adverse effects was similar between both Groups, Hydroxychloroquine and Control (3.7% versus 2.9%; pooled risk ratio 1.22; 95% confidence interval: 0.76-1.96). CONCLUSION: Hydroxychloroquine is not efficacious in reducing mortality of COVID-19 patients. PROSPERO DATABASE REGISTRATION: (www.crd.york.ac.uk/prospero) under number CRD42020197070.

Disability of Arm, Shoulder and Hand and Michigan Hand Outcomes Questionnaires: Exploring Responsiveness and Diagnostic Performance in a Sample of Outpatients with and without Hand and Wrist Complaints.

Objective The present study aimed to verify whether, in an adult population with nontraumatic complaints in the upper limbs, (1) the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and the Michigan Hand Outcomes Questionnaire (MHQ) are susceptible to a "ceiling effect" when compared with a sample of healthy subjects; and (2) to determine cutoff points for diagnostic performance and the intercorrelation for DASH and MHQ in both samples. Methods This was a prospective, comparative, nonrandomized study. In total, 150 subjects were included, with 75 in the case group (with disease) and 75 in the control group (without disease). This was a sample of patients recently admitted to a hand surgery outpatient clinic. Controls were matched to clinical cases according to inclusion. The ceiling effect was determined by a maximum response rate (> 15%); receiver operating characteristic (ROC) curves determined cutoff points for sickness definition, and DASH and MHQ sensitivity and specificity. Statistical significance was set at p < 0.05. Results The DASH and MHQ questionnaires had no ceiling effect for the case group. In this group, 18 (24%) patients had the maximum DASH score, but none (0%) had the maximum MHQ score. For the control group, 1 (1.33%) subject had the maximum DASH score, but none scored for MHQ. For case determination, DASH scores of 7.1 had 80% sensitivity and 60.3% specificity, whereas MHQ scores of 76.9 had 56.2% sensitivity and 97.3% specificity. Conclusion The DASH and MHQ questionnaires are reliable tools to measure the impact of hand and wrist morbidities on daily activities, and they are not susceptible to ceiling effects. The DASH questionnaire is more sensitive for patient identification, whereas the MHQ is more specific. As such, the MHQ seems more appropriate when a more specific functional increase is expected.

THE EFFECT OF THE USE OF ALCOHOL AND DRUGS ON MOTORCYCLICAL TRAUMAS WITH SURGICAL TREATMENT FRACTURES: EPIDEMIOLOGY.

Objective: To verify the prevalence of patients who were victims of motorcycle trauma who were under the influence of alcohol and drugs. Methods: The study was observational and prospective, with patients hospitalized to the Orthopedics and Traumatology Ward of Hospital São Paulo (UNIFESP), from March 2015 to March 2016. The study included patients of all genders, over 18 years old, hospitalized due to motorcycle trauma and who needed orthopedic surgical treatment. Results: During the research, 282 patients were hospitalized, of which 23.8% were victims of motorcycle trauma. Of these, 49.3% motorcyclists reported the use of alcohol and drugs before the accident, while 50.7% denied their consumption. In the analysis of alcohol and drug consumption in patients with motorcycle injuries, the results showed that: 65% used only alcohol; 16% used both alcohol and drugs; and 19% used only illicit drugs. Conclusion: The incidence of patients who suffered motorcycle accidents under the influence of alcohol and drugs was 49.3%. Level of Evidence IV, Prospective Case Series.

Resumo Objetivo Verificar se, em uma população adulta com queixa não traumática dos membros superiores, (1) os questionários Disability of the Arm, Shoulder and Hand (DASH, na sigla em inglês) e Michigan Hand Questionnaire (MHQ, na sigla em inglês) estão suscetíveis ao "efeito de teto", comparando com amostra de não-doentes; (2) determinar pontos de corte de performance diagnóstica e correlação interquestionários para DASH e MHQ em ambas as amostras. Método Estudo prospectivo, comparativo e não randomizado. Incluímos 150 pacientes, 75 no grupo caso (com doença) e 75 no grupo controle (sem doença). Trata-se de amostra de pacientes recém-admitidos em ambulatório de cirurgia da mão. Os controles foram pareados de forma balanceada de acordo com a inclusão dos casos. Determinamos a presença de efeito de teto por meio da taxa de respostas máximas (> 15%) e associamos curvas receiver operating characteristic (ROC, na sigla em inglês) para a determinação de pontos de corte para a determinação de doentes, associados a medidas de sensibilidade e especificidade. Consideramos p < 0.05 para significância estatística. Resultados Os questionários DASH e MHQ não demonstraram o efeito de teto para o grupo com doença. A porcentagem de pacientes do grupo caso com nota máxima foi de n = 18 (24%) no DASH e de 0% no MHQ. Para o grupo sem doença, 1 (1,33%) dos participantes pontuou com nota máxima para DASH, enquanto nenhum pontuou para o MHQ. Na determinação de casos, escores de DASH de 7,1 apresentam sensibilidade de 80% e especificidade de 60,3%. Para o MHQ, um escore de 76,9 apresenta sensibilidade de 56,2% e especificidade de 97,3%. Conclusão Os questionários DASH e MHQ são ferramentas confiáveis na mensuração do impacto das morbidades das mãos e dos punhos nas atividades diárias dos pacientes e não são suscetíveis a efeito de teto. O questionário DASH é mais sensível para a identificação de doentes, enquanto o MHQ é mais específico. Em situações nas quais se espera um incremento funcional mais discreto (ou mais específico), o MHQ parece mais adequado.

WALANT versus intravenous regional anesthesia for carpal tunnel syndrome: a randomized clinical trial

ABSTRACT BACKGROUND: There are several anesthetic techniques for surgical treatment of carpal tunnel syndrome (CTS). Results from this surgery using the "wide awake local anesthesia no tourniquet" (WALANT) technique have been described. However, there is no conclusive evidence regarding the effectiveness of the WALANT technique, compared with the usual techniques. OBJECTIVE: To evaluate the effectiveness of the WALANT technique, compared with intravenous regional anesthesia (IVRA; Bier's block), for surgical treatment of CTS. DESIGN AND SETTING: Randomized clinical trial, conducted at Hospital Alvorada Moema and the Discipline of Hand Surgery, Universidade Federal de São Paulo (UNIFESP), São Paulo (SP), Brazil. METHODS: Seventy-eight patients were included. The primary outcome was measurement of perioperative pain through a visual analogue scale (VAS). The secondary outcomes were the Boston Questionnaire score, Hospital Anxiety and Depression Scale (HADS) score, need for use of analgesics, operating room times, remission of paresthesia, failures and complications. RESULTS: The WALANT technique (n = 40) proved to be superior to IVRA (n = 38), especially for controlling intraoperative pain (0.11 versus 3.7 cm; P < 0.001) and postoperative pain (0.6 versus 3.9 cm; P < 0.001). Patients spent more time in the operating room in the IVRA group (59.5 versus 46 minutes; P < 0.01) and needed to use more analgesics (10.8 versus 5.7 dipyrone tablets; P = 0.02). Five IVRA procedures failed (5 versus 0; P = 0.06). CONCLUSIONS: The WALANT technique is more effective than IVRA for CTS surgery.

Onset of Trigger Finger after Carpal Tunnel Syndrome Surgery: Assessment of Open and Endoscopic Techniques.

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.

Diagnosis and Treatment of Trigger Finger in Brazil - A Cross-Sectional Study.

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.

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.

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.

Resumo Objetivo Avaliar o planejamento terapêutico para o dedo em gatilho por ortopedistas brasileiros. Métodos Estudo transversal, cuja população foi composta por participantes do Congresso Brasileiro de Ortopedia e Traumatologia 2018 (CBOT-2018). Foi aplicado um questionário sobre a conduta adotada no diagnóstico e tratamento do dedo em gatilho. Resultados Foram analisados 243 participantes com média de idade de 37.46 anos, na maioria homens (88%), tempo de experiência de pelo menos 1 ano (55,6%), e da região Sudeste (68.3%).

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.

Circular saw misuse is related to upper limb injuries: a cross-sectional study.

OBJECTIVES: Machinery injuries account for a substantial share of traumatic upper limb injuries (TULIs) affecting young active individuals. This study is based on the hypothesis that there is an important relationship between the improper use of power saws and TULIs. The aim of the study is to assess the prevalence and epidemiology of TULIs caused by power saws and determine the risks related to power saw use. METHODS: A cross-sectional evaluation of medical records from a two-year period was performed. Patients sustaining TULIs related to power saws were analyzed. Data on the epidemiology, site of injury, mechanism of trauma, technical specifications of the tool, cutting material, personal protective equipment, time lost and return to work were obtained. RESULTS: A database search retrieved 193 TULI records, of which 104 were related to power saws. The majority of patients were male (102/104; 98.1%), right-handed (97/104; 93.3%), and manual workers (46/104; 44.2%), with an average age of 46.8 years. The thumb was the most frequently injured site (32/93; 34.4%). Most of the injuries were caused by manual saws (85/104; 81.7%), and masonry saws accounted for 68.2% (58/85) of the cases. Masonry saws improperly used for woodwork resulted in 86.2% (50/58) of the injuries. TULI caused by masonry saws was 5 times higher in manual workers than in other patients. In addition, masonry saws had a risk of kickback 15 times higher than that of other saws, and the risk of injury increased by 5.25 times when the saws were used improperly for wood cutting. CONCLUSIONS: The profile of TULIs related to power saws was demonstrated and was mainly associated with manual saws operated by manual workers that inappropriately used masonry saws for woodworking.

Treatment of fingertip injuries by specialists in hand surgery in brazil / Tratamento de lesões da ponta dos dedos por especialistas em cirurgia da mão no brasil

ABSTRACT Objective: To verify if there is consensus about the treatment of each type of injury or amputation of the fingertips, and if there is a statistical difference among the treatment options according to the surgeon's length of time in the hand surgery specialty. Methods: A cross-sectional survey was conducted during the 37th Brazilian Congress of Hand Surgery, when one hundred and twenty questionnaires were randomly distributed. Observing the inclusion and exclusion criteria, ninety completed questionnaires were included. The answers were submitted to descriptive and inferential analysis with a significance level of p <0.05. Results: This study showed agreement of 63.3% for the treatment with statistical difference for dorsal oblique injury less than 1 cm with bone exposure for the VY advancement flap alternative; 46.7% for volar tip oblique injury with bone exposure less than 1 cm for the Cross Finger alternative; 47.8% for oblique thumb volar injury greater than 1 cm with no bone exposure to the Moberg alternative; 54.4% for thumb pulp injury up to 2.5 cm with bone exposure to the Moberg alternative with proximal release, and 92.2% for antibiotic use, for the "cephalexin" alternative. Conclusion: There is no consensus regarding the treatment of most types of fingertip lesions, with agreement of 45.4%. When we subdivided by time group of specialty in hand surgery, there was an increase in agreement to 54.5% of the questions per subgroup. Further comparative studies are needed to assess the consensus among surgeons regarding the treatment of fingertip injury. Level of Evidence III; Cross-sectional survey.

RESUMO Objetivo: Verificar se há consenso sobre o tratamento de cada tipo de lesão ou amputação da ponta do dedo e se há diferença estatística entre as opções de tratamento de acordo com o tempo em que o cirurgião atua na especialidade de cirurgia da mão. Métodos: Pesquisa transversal realizada durante o 37° Congresso Brasileiro de Cirurgia da Mão, quando foram distribuídos cento e vinte questionários de forma aleatória. Observando-se os critérios de inclusão e exclusão, noventa questionários respondidos foram incluídos. As respostas foram submetidas a análise descritiva e inferencial com índice de significância de p < 0,05. Resultados: Este estudo apresentou concordância no tratamento com diferença estatística para lesão oblíqua dorsal menor que 1 cm com exposição óssea para a alternativa de retalho de avanço VY com 63,3%; lesão oblíqua volar com exposição óssea menor que 1 cm para a alternativa Cross Finger com 46,7%; lesão oblíqua volar do polegar maior de 1 cm sem exposição óssea para a alternativa Moberg com 47,8%; lesão da polpa do polegar com até 2,5 cm com exposição óssea para a alternativa Moberg com liberação proximal com 54,4% e uso de antibióticos para a alternativa "cefalexina" com 92,2%. Conclusão: Não há consenso quanto ao tratamento da maioria dos tipos de lesão da ponta do dedo, sendo que houve concordância em 45,4%. Quando subdividimos por grupo de tempo de especialização em cirurgia de mão, verificou-se aumento da concordância para 54,5% das questões por subgrupo. Há necessidade de realização de novos estudos comparativos para avaliarmos o consenso entre os cirurgiões com relação ao tratamento da lesão das pontas dos dedos.
