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.

Prevalence of Absence of Palmaris Longus Tendon in a Population Sample from a Multiethnic Brazilian City.

Objective The objective of the study was to determine the prevalence of absence of palmaris longus tendon in a population sample from a multiethnic Brazilian city. Methods A cross-sectional observational study was carried out between October 2017 and April 2018. We included male and female volunteers aged 18 years or older. The absence of palmaris longus tendon was determined by asking the volunteers to perform the Schaeffer test bilaterally. Results We prospectively collected data on 1,008 volunteers, 531 male and 477 female, with age between 18 and 74 years (mean 38.4 years). The absence of palmaris longus tendon was observed in 264 (26.2%) volunteers. Bilateral absence was detected in 123 volunteers (12.2%), 60 female (48.8%) and 63 male (51.2%). Unilateral absence was found in 141 patients (14.0%), 54 female (38.2%) and 87 male (61.8%) ( p < 0.05). Conclusion The prevalence of absence of palmaris longus tendon in our study was 26.2%. There was no statistically significant difference between gender and bilaterally. The absence of palmaris longus tendon was predominant on unilateral right side in males.

An Intraindividual Comparison of Open versus Paine Retinaculotome Release for Bilateral Carpal Tunnel Syndrome.

The main purpose of this research was to do an intraindividual comparison of outcomes between the open ulnar incision (OUI) and the Paine retinaculotome with palmar incision (PRWPI) techniques in patients with bilateral carpal tunnel syndrome (CTS). The patients underwent OUI surgery on one hand and PRWPI surgery on the contralateral hand. The patients were evaluated with the Boston carpal tunnel questionnaire, visual analogue scale for pain, palmar grip strength, and fingertip, key, and tripod pinch strengths. Both hands were examined in the preoperative and postoperative periods after 2 weeks, 1 month, and 3 and 6 months. Eighteen patients (36 hands) were evaluated. The symptoms severity scale (SSS) scores were higher, in the preoperative period, in the hands that underwent surgery with PRWPI ( p -value = 0,023), but lower in the 3rd month postoperative ( p -value = 0.030). The functional status scale (FSS) scores were lower in the periods of 2 weeks, 3 months, and 6 months ( p -value = 0,016) on the hands that underwent surgery with PRWPI. In a different two-group module study, the PRWPI group presents the SSS scores average on the 2nd week and 1st month, and the FSS scores average on the 2nd week, less 0.8 and 1.2 points respectively comported to open group. The hands that underwent surgery with PRWPI presented significantly lower SSS scores at 3 months postoperative, and lower FSS scores at 2 weeks, and 3 and 6 months postoperative, compared to open surgery group.

Use of aerobic treadmill exercises on nerve regeneration after sciatic nerve injury in spontaneously hypertensive rats.

PURPOSE: Various postoperative protocols have been proposed to improve outcomes and accelerate nerve regeneration. Recently, the use of physical exercise in a post-surgical neurorraphy procedure has shown good results when started early. We experimentally investigated the hypothesis that post-operative exercise speeds up results and improves clinical and morphologic parameters. METHODS: Isogenic rats were randomly divided into four groups: 1 SHAM; 2 SHAM submitted to the exercise protocol (EP); 3 Grafting of the sciatic nerve; and 4 Grafting of the sciatic nerve associated with the EP. The EP was based on aerobic activities with a treadmill, with a progressive increase in time and intensity during 6 weeks. The results were evaluated by the sciatic functional index (SFI), morphometric and morphologic analysis of nerve distal to the lesion, and the number of spinal cord motor neurons, positive to the marker Fluoro-Gold (FG), captured retrogradely through neurorraphy. RESULTS: Functional analysis (SFI) did not show a statistical difference between the group grafted with (-50.94) and without exercise (-65.79) after 90 days. The motoneurons count (Spinal cord histology) also showed no diference between these groups (834.5 × 833 respectively). Although functionally there is no difference between these groups, morphometric study showed a greater density (53.62) and larger fibers (7.762) in GRAFT group. When comparing both operated groups with both SHAM groups, all values were much lower. CONCLUSIONS: The experimental model that this aerobic treadmill exercises protocol did not modify nerve regeneration after sciatic nerve injury and repair with nerve graft.

Failure factors for carpal tunnel syndrome surgical treatment: When and how to perform a revision carpal tunnel decompression surgery.

Despite being a procedure widely used all over the world with high rates of symptom remission, surgical treatment of carpal tunnel syndrome may present unsatisfactory outcomes. Such outcomes may be manifested clinically by non-remission of symptoms, remission of symptoms with recurrence a time after surgery or appearance of different symptoms after surgery. Different factors are related to this unsuccessful surgical treatment of carpal tunnel syndrome. Prevention can be achieved through a thorough preoperative clinical evaluation of the patient. As such, the surgeon will be able to make differential or concomitant diagnoses, as well as determine factors related to patient dissatisfaction. Perioperative factors include the correct identification of anatomical structures for complete median nerve decompression. Numerous procedures have been described for managing postoperative factors. Among them, the most common is adhesion around the median nerve, which has been treated with relative success using different vascularized flaps or autologous or homologous tissue coverage. The approach to cases with unsuccessful surgical treatment of carpal tunnel syndrome is discussed in more detail in the text.

Resumo Apesar de ser um procedimento amplamente utilizado em todo o mundo e com elevadas taxas de remissão dos sintomas, o tratamento cirúrgico da síndrome do túnel do carpo pode apresentar resultados não satisfatórios ao paciente. Esse resultado não satisfatório pode se manifestar clinicamente pela não remissão dos sintomas, remissão dos sintomas mas recorrência desses após um período de tempo da cirurgia ou aparecimento de diferentes sintomas após a cirurgia. Diferentes fatores estão relacionados a esse insucesso do tratamento cirúrgico da síndrome do túnel do carpo (ITCSTC). A prevenção pode ser conseguida por meio de minuciosa avaliação clínica do paciente no período pré-operatório. Dessa forma o cirurgião poderá fazer diagnósticos diferenciais ou diagnósticos concomitantes, assim como identificar fatores ligados a insatisfação do paciente. Os fatores per-operatórios incluem a correta identificação das estruturas anatômicas para completa descompressão do nervo mediano. Inúmeros procedimentos têm sido descritos para o tratamento dos fatores que ocorrem no período pós-operatório. Desses o mais comum, a formação de aderências em torno do nervo mediano, tem sido tratado com relativo sucesso utilizando diferentes retalhos vascularizados ou cobertura com o uso de tecido autólogo ou homólogo. Descreveremos a abordagem do ITCSTC com maiores detalhes no texto.

COVID-19 AND UPPER LIMB ANOMALIES IN NEWBORNS: A REASON FOR CONCERN?

The relationship between viral infection in pregnancy and congenital anomalies is reported in the medical literature. The risks for the SARS-CoV-2 virus interfering with implantation, growth, and fetal development are not yet known. Many drugs with potential teratogenic risk are being used for treatment. The studies with the vaccine excluded pregnant women from clinical trials, currently preventing high-quality evidence. We present a review of the most common anomalies in the upper extremities caused by congenital viral infection and the risks of anti-COVID-19 therapy and vaccine during pregnancy. We aim to alert orthopedic and hand surgeons to the possibility of these conditions in the future. Level of evidence V; Narrative review.

Assessment of the Effects of Swimming as a Postoperative Rehabilitation on Nerve Regeneration of Wistar Rats Submitted to Grafting of Autologous Nerves after Injury to the Sciatic Nerve.

Objective To evaluate the effects of swimming on nerve regeneration after sciatic nerve injury in Wistar rats. Methods A total of 30 Wistar rats was divided into 3 groups: Sham + Nat group animals that were not submitted to graft surgery and were submitted to swimming ( n = 10); Graft group: animals submitted to autologous sciatic nerve graft ( n = 10); and Graft + Nat group: animals submitted to autologous sciatic nerve graft surgery and to swimming ( n = 10). The results were analyzed on the software (GraphPad Software, San Diego, CA, USA). Results In the first evaluation, all sciatic functional index (SFI) values were similar ( p = 0.609). Thirty days after the surgical procedure, we observed differences between all the comparisons: Sham + Nat (-34.64 ± 13.89) versus Graft (-145.9 ± 26.06); Sham + Nat versus Graft + Nat (-89.40 ± 7.501); Graft (-145.9 ± 26.06) versus Graft + Nat (-89.40 ± 7.501). In the measurements (60 and 90 days), there was no statistical difference between the Graft and Graft + Nat groups, with significantly lower values in relation to the control group ( p < 0.001). The number of motor neurons presented differences in the comparisons between the Sham + Nat and Graft groups (647.1 ± 16.42 versus 563.4 ± 8.07; p < 0.05), and between the Sham + Nat and Graft + Nat groups (647.1 ± 16.42 versus 558.8 ± 14.79; p < 0.05). There was no difference between the Graft and Graft + Nat groups. Conclusion Animals submitted to the swimming protocol after the sciatic nerve grafting procedure did not present differences in the SFI values and motor neuron numbers when compared to the control group. Therefore, this type of protocol is not efficient for the rehabilitation of peripheral nerve lesions that require grafting. Therefore, further studies are needed.

Prevalence of the Linburg-Comstock Anomaly in a Brazilian Population Sample.

Objective To determine the prevalence of the Linburg-Comstock anomaly in a Brazilian population sample. Methods A cross-sectional observational study was carried out between October 2017 and April 2018. We included male and female volunteers aged 18 years or older. The presence of the Linburg-Comstock anomaly was determined by performing the clinical tests described by Linburg and Comstock. The data were analyzed using the GraphPad Prism software, and we considered differences with p < 0.05. Results The study analyzed 1,008 volunteers (2,016 hands) with a mean age of 38.3 years, 531 (52.67%) of which were male, and 477 (47.33%) were female. The Linburg-Comstock anomaly was diagnosed in 564 (55.95%) individuals, and it was bilateral in 300 (53.2%) of them, right-sided in 162 (28.72%), and left-sided in 102 (18.08%). No significant differences were found when comparing the prevalence between genders. However, a the prevalence of the right-sided anomaly in the male population (n = 99; 70.21%) was higher than in the female one (n = 63; 51.21%), with p = 0.0016. In addition, the presence of pain by the maneuver described by Linburg and Comstock was more prevalent in women (n = 150; 54.94%) than in men (n = 105; 36.08%), with p = 0.0001. These results show the importance of epidemiological studies on the Linburg-Comstock anomaly, mainly in order to investigate the presence of associated conditions. Conclusion The prevalence of the Linburg-Comstock anomaly in the studied population was of 55.95%, and it was bilateral in 53.2% of the volunteers. The presence of the connection was observed more frequently in the right side and among men, but the pain symptom was more frequent among women.

Resumo Objetivo Determinar a prevalência da anomalia de Linburg-Comstock em uma amostra populacional brasileira. Métodos Estudo observacional transversal realizado no período de outubro de 2017 a abril de 2018. Foram incluídos voluntários dos gêneros feminino e masculino, com idade igual ou superior a 18 anos. A presença da anomalia de Linburg-Comstock foi determinada pela realização dos testes clínicos descritos por Linburg e Comstock. Os dados foram analisados por meio do software GraphPad Prism, sendo consideradas diferenças com valores de p < 0,05. Resultados O estudo analisou 1.008 voluntários (2.016 mãos) com idade média de 38,3 anos, dos quais 531 (52,67%) eram do gênero masculino, e 477 (47,33%) eram do gênero feminino. A anomalia de Linburg-Comstock foi diagnosticada em 564 voluntários (55,95%) da população estudada, sendo bilateral em 300 (53,2%), direita em 162 (28,72%), e esquerda em 102 (18,08%). Não foram encontradas diferenças significativas quando se comparou a prevalência entre os gêneros. Porém, foi encontrada uma maior prevalência da anomalia direita na população masculina (n = 99; 70,21%) do que na feminina (n = 63; 51,21%), com p = 0,0016. Além disso, a presença da dor pela manobra descrita por Linburg e Comstock foi mais prevalente nas mulheres (n = 150; 54,94%) do que nos homens (n = 105; 36,08%), com p = 0,0001. Estes resultados mostram a importância dos estudos epidemiológicos sobre a anomalia de Linburg-Comstock, principalmente com o intuito de investigar a presença de afecções associadas. Conclusão A prevalência da anomalia de Linburg-Comstock na população estudada foi de 55,95%, sendo bilateral em 53,2% dos voluntários. A presença da conexão foi observada com maior frequência do lado direito em homens, mas o sintoma dor foi mais frequente nas mulheres.

Assessment of the Effects of Swimming as a Postoperative Rehabilitation on Nerve Regeneration of Wistar Rats Submitted to Grafting of Autologous Nerves after Injury to the Sciatic Nerve / Avaliação dos efeitos da natação como reabilitação pós-operatória na regeneração nervosa de ratos da linhagem Wistar submetidos a enxerto de nervos autólogos após lesão do nervo ciático

Abstract Objective To evaluate the effects of swimming on nerve regeneration after sciatic nerve injury in Wistar rats. Methods A total of 30 Wistar rats was divided into 3 groups: Sham + Nat group animals that were not submitted to graft surgery and were submitted to swimming (n = 10); Graft group: animals submitted to autologous sciatic nerve graft (n = 10); and Graft + Nat group: animals submitted to autologous sciatic nerve graft surgery and to swimming (n = 10). The results were analyzed on the software (GraphPad Software, San Diego, CA, USA). Results In the first evaluation, all sciatic functional index (SFI) values were similar (p = 0.609). Thirty days after the surgical procedure, we observed differences between all the comparisons: Sham + Nat (−34.64 ± 13.89) versus Graft (−145.9 ± 26.06); Sham + Nat versus Graft + Nat (−89.40 ± 7.501); Graft (−145.9 ± 26.06) versus Graft + Nat (−89.40 ± 7.501). In the measurements (60 and 90 days), there was no statistical difference between the Graft and Graft + Nat groups, with significantly lower values in relation to the control group (p < 0.001). The number of motor neurons presented differences in the comparisons between the Sham + Nat and Graft groups (647.1 ± 16.42 versus 563.4 ± 8.07; p < 0.05), and between the Sham + Nat and Graft + Nat groups (647.1 ± 16.42 versus 558.8 ± 14.79; p < 0.05). There was no difference between the Graft and Graft + Nat groups. Conclusion Animals submitted to the swimming protocol after the sciatic nerve grafting procedure did not present differences in the SFI values and motor neuron numbers when compared to the control group. Therefore, this type of protocol is not efficient for the rehabilitation of peripheral nerve lesions that require grafting. Therefore, further studies are needed.

Resumo Objetivo Avaliar os efeitos da natação na regeneração nervosa após a lesão do nervo ciático em ratos Wistar. Métodos Um total de 30 ratos Wistar foram divididos em 3 grupos: grupo Sham + Nat: animais que não foram submetidos à cirurgia de enxerto e foram submetidos à natação (n = 10); grupo Enxerto: animais que foram submetidos à cirurgia de enxerto autólogo de nervo ciático (n = 10); e grupo Enx + Nat: animais submetidos à cirurgia de enxerto autólogo de nervo ciático e à natação (n = 10). Os resultados foram analisados pelo software GraphPad Prism 5.0 (GraphPad Software, San Diego, CA, EUA). Resultados Na primeira avaliação, todos os valores do índice funcional do ciático (IFC) foram semelhantes (p = 0.609). Após 30 dias do procedimento cirúrgico, foram observadas diferenças entre todas as comparações: Sham + Nat (−34,64 ± 13,89) versus Enxerto (−145,9 ± 26,06), grupos Sham + Nat versus Enx + Nat (−89,40 ± 7,501), grupos Enxerto (−145,9 ± 26,06) versus Enx + Nat (−89,40 ± 7,501). Nas medidas (60 e 90 dias), não houve diferença estatística entre os grupos Enxerto e Enx + Nat, com valores significativamente menores em relação ao grupo controle (p < 0,001). O número de motoneurônios apresentou diferenças nas comparações entre os grupos Sham + Nat e Enxerto (647,1 ± 16,42 versus 563,4 ± 8,07; p < 0,05) e Sham + Nat e Enx + Nat (647,1 ± 16,42 versus 558,8 ± 14,79; p < 0,05), não havendo diferença entre os grupos Enxerto e Enx + Nat. Conclusão Os animais submetidos ao protocolo de natação após o procedimento de enxerto do nervo ciático não apresentaram diferenças nos valores de IFC e nos números de motoneurônios quando comparados com grupo controle. Portanto, este tipo de protocolo não é eficiente para reabilitação de lesões nervosas periféricas que necessitam de enxerto, sendo necessários novos estudos.
