Abstract Carpal tunnel syndrome is median nerve symptomatic compression at the level of the wrist, characterized by increased pressure within the carpal tunnel and decreased nerve function at the level. Carpal tunnel release decreases pressure in Guyon's canal, via open techniques, with symptom and two-point discrimination improvement in the ulnar nerve distribution. We hypothesize that endoscopic carpal tunnel release improves two-point discrimination in the ulnar nerve distribution as well. This study includes 143 patients who underwent endoscopic carpal tunnel release between April 2016 to June 2019 in a single, community-based teaching hospital. A comprehensive retrospective chart review was performed on patient demographics, preand post-operative two-point discrimination test results, and complications. The effects of sex, age, and diabetes mellitus in the ulnar and median nerve territories with two-point discrimination tests were analyzed. As well as the differences in two-point discrimination among patient's based on their smoking status. There were significant post operative improvements in both the median (7.7 vs 4.4 mm, p < 0.001) and ulnar (5.7 vs 4.1 mm, p < 0.001) nerve territories. Smoking status, sex, age and diabetes did not significantly affect two-point discrimination outcomes. In conclusion the endoscopic release of the transverse carpal ligament decompresses the carpal tunnel and Guyon's canal, demonstrating improvement in two-point discrimination in both the ulnar and median nerve distributions.

Resumen El síndrome de túnel carpiano es la compresión sintomática del nervio mediano al nivel de la muñeca. Se caracteriza por un aumento de presión dentro del túnel y una disminución de la función del nervio a ese nivel. La liberación del túnel carpiano descomprime el canal de Guyon, con mejoría sintomática y en la prueba de discriminación de dos puntos en la distribución del nervio cubital. Hipotetizamos que la liberación endoscópica mejora de la misma manera en la distribución del nervio cubital. Este trabajo incluye 143 pacientes que tuvieron liberación endoscópica del túnel carpiano entre abril del 2016 y junio del 2019 en un hospital Universitario de la comunidad. Se evaluaron retrospectivamente las historias clínicas para los datos demográficos, los resultados pre y post quirúrgicos en la prueba de discriminación de dos puntos y complicaciones. Se analizaron los efectos del sexo, edad, tabaco y diabetes en los resultados de la prueba de discriminación de dos puntos para los nervios cubital y mediano. Hubo mejoría significativa post quirúrgica en la prueba de discriminación de dos puntos para los nervios mediano (7.7 vs 4.4 mm, p < 0.001) y cubital (5.7 vs 4.1 mm, p < 0.001). Fumadores, sexo, edad, y diabetes no afectaron de forma significativa. Concluimos que la liberación endoscópica del ligamento transverso del carpo descomprime el túnel carpiano y el canal de Guyon con mejoría en la prueba de discriminación de dos puntos para los nervios cubital y mediano.

Abstract Objective The present study aimed at analyzing the clinical, radiological and functional results of the reconstruction of the distal radius after tumor resection with a custom-made metal arthrodesis implant and compare them with other types of distal radius reconstruction, as presented in the literature. To our best knowledge, this is the first article describing this particular type of implant and patient functionality. Methods Functional outcomes of reconstruction of the distal radius were assessed in a series of 4 patients. Three of the patients having had resection of giant cell tumors (GCTs), one patient having had resection of osteosarcoma. Results There were no major implant-related complications like infection, nonunion or loosening. Two patients had to undergo further surgery for protruding metalwork. Overall function was good according to the Musculoskeletal Tumor Society MSTS and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. Conclusion The present study shows that custom-made metal arthrodesis implant benefits from the fact that it can be used as a salvage option when other treatments have failed, or it can be used as a primary option in cases in which there is limited bone stock after distal radius tumor resection.

Resumo Objetivo O presente estudo teve como objetivo analisar os resultados clínicos, radiológicos e funcionais da reconstrução do rádio distal após a ressecção do tumor com implante metálico personalizado de artrodese e compará-los com outros tipos de reconstrução do rádio distal, conforme apresentado na literatura. Pelo que conhecemos, este é o primeiro artigo descrevendo esse tipo particular de implante e funcionalidade no paciente. Métodos Os desfechos funcionais de reconstrução do rádio distal foram avaliados em uma série de 4 pacientes. Três dos pacientes tiveram ressecção de tumores de células gigantes (TCGs), sendo um paciente com ressecção de osteossarcoma. Resultados Não houve complicações relacionadas ao implante, como infecção, não sindicalidade ou afrouxamento. Dois pacientes tiveram que passar por uma nova cirurgia para a protusão da prótese metálica. A função geral foi boa de acordo com as pontuações da Musculoskeletal Tumor Society (MSTS) e Disabilities of the Arm, Shoulder, and Hand (DASH). Conclusão O estudo mostra que o implante metálico personalizado de artrodese se beneficia do fato de que pode ser usado como opção de salvamento quando outros tratamentos falharam, ou pode ser usado como opção primária nos casos em que há estoque ósseo limitado após a ressecção do tumor do rádio distal.

El osteoma osteoide es una lesión ósea benigna que, habitualmente, se acompaña de clínica típica caracterizada por dolor nocturno que mejora con antiinflamatorios no esteroideos. Aunque la presentación clínica es típica, con frecuencia, es común la demora diagnóstica, en especial, en los casos con localización atípica.Se presenta el caso de una paciente de 10 años con dolor en la muñeca izquierda de dos años de evolución con diagnóstico de osteoma osteoide localizado en el hueso grande del carpo. La localización atípica de la lesión conllevó un retraso diagnóstico importante

Osteoid osteoma is a benign bone lesion that is usually accompanied by a typical clinical condition characterized by night pain that improves with non-steroidal anti-inflammatory drugs. Although the clinical presentation is frequently typical, diagnostic delay is common, especially in cases with an atypical location.We report the case of a 10-year-old patient with left wrist pain of two years of evolution with diagnosis of osteoid osteoma located in capitate bone. The atypical location of the lesion led to a significant diagnostic delay.

Abstract Objective To analyze the anatomical variations of the motor branches of the radial nerve in the elbow region. The origin, course, length, branches, motor points and relationships with neighboring structures were evaluated. Materials and Methods Thirty limbs from15 adult cadavers were dissected and prepared by intra-arterial injection of a 10% glycerin and formaldehyde solution. Results The first branch of the radial nerve in the forearm went to the brachioradialis muscle (BR), originating proximally to the division of the radial nerve into superficial branch of the radial nerve (SBRN) and posterior interosseous nerve (PIN) in all limbs. The branches to the extensor carpi radialis longus muscle (ECRL) detached from the proximal radial nerve to its division into 26 limbs, in 2, at the dividing points, in other 2, from the PIN. In six limbs, the branches to the BR and ECRL muscles originated from a common trunk. We identified the origin of the branch to the extensor carpi radialis brevis muscle (ECRB) in the PIN in 14 limbs, in the SBRN in 12, and in the radial nerve in only 4. The branch to the supinator muscle originated from the PIN in all limbs. Conclusion Knowledge of the anatomy of the motor branches of the radial nerve is important when performing surgical procedures in the region (such as the approach of the proximal third and the head of the radius, release of compressive syndromes of the posterior interosseous nerve and radial tunnel, and distal nerve transfers) in order to understand the order of recovery of muscle function after a nerve injury.

Resumo Objetivo Analisar as variações anatômicas dos ramos motores do nervo radial na região do cotovelo. Foram avaliadas a origem, curso, comprimento, ramificações, pontos motores e relações com estruturas vizinhas. Materiais e Métodos Foram dissecados 30 membros de 15 cadáveres adultos, preparados por injeção intra-arterial de uma solução de glicerina e formol a 10%. Resultados O primeiro ramo do nervo radial no antebraço foi para o músculo braquiorradial (BR), que se origina proximalmente à divisão do nervo radial em ramo superficial do nervo radial (RSNR) e nervo interósseo posterior (NIP) em todos os membros. Os ramos para o músculo extensor radial longo do carpo (ERLC) se desprenderam do nervo radial proximalmente à sua divisão em 26 membros, em 2, nos pontos de divisão, em outros 2, do NIP. Em seis, os ramos para os músculos BR e ERLC originavam-se de um tronco comum. Identificamos a origem do ramo para o músculo extensor radial curto do carpo (ERCC) no NIP em 14 membros, no RSNR em 12, e no nervo radial em apenas 4. O ramo para o músculo supinador originou-se do NIP em todos os membros. Conclusão O conhecimento da anatomia dos ramos motores do nervo radial é importante quando se realizam procedimentos cirúrgicos na região, como a abordagem do terço proximal e da cabeça do rádio, a liberação das síndromes compressivas do nervo interósseo posterior e do túnel radial, as transferências nervosas distais, e para entender a ordem de recuperação da função muscular após uma lesão nervosa.

The aim of this study is to investigate rs1805086 and rs1805065 polymorphisms of MSTN gene of national and amateur Turkish arm wrestlers and people leading a sedentary lifestyle, and the anthropometric properties such as hand, wrist, and forearm circumferences of national and amateur Turkish arm wrestlers are aimed to be explored. In this study, a total of 79 volunteers who were 24 national (7 females, 17 males) Turkish arm wrestlers, 21 amateur (7 females, 14 males) Turkish arm wrestlers and 34 sedentary people (12 females, 22 males) participated. To analyse the data, Statistical Package for the Social Sciences, SPSS 22 (SPSS Inc., Chicago, IL, USA) was used. As a result of the study, when data on rs1805086 and rs1805065 polymorphisms of MSTN gene were examined respectively, it was found out that MSTN 153KK genotype was 100.0% dominant in both national (n=24) and amateur (n=21) arm wrestlers, and it was 94.12 % dominant in sedentary people. KR genotype was observed in 5.88 % of the sedentary people. The data from the other rs1805065 polymorphism of MSTN gene showed that all participants (n = 45, 100.0 %) were carriers of normal homozygous genotype. Furthermore, for both female group and male group, there found to be statistically significant difference in terms of anthropometric properties. It can be concluded that though there was no significant difference between national and amateur Turkish arm wrestlers in terms of their MSTN gene characteristics; in terms of anthropometric properties, significant differences were discovered. It was found out that on these athletes, not MSTN gene polymorphisms but anthropometric properties were effective.

El objetivo de este estudio fue investigar los polimorfismos rs1805086 y rs1805065 del gen MSTN de luchadores de brazos turcos, nacionales y aficionados, y personas que llevan un estilo de vida sedentario, y las propiedades antropométricas además de las circunferencias de manos, muñecas y antebrazos de los luchadores de brazos turcos nacionales y aficionados. En este estudio, participaron un total de 79 voluntarios: 24 luchadores de brazos turcos nacionales (7 mujeres, 17 hombres), 21 luchadores de brazos turcos aficionados (7 mujeres, 14 hombres) y 34 personas sedentarias (12 mujeres, 22 hombres). Para analizar los datos, se utilizó el Paquete Estadístico para las Ciencias Sociales, SPSS 22 (SPSS Inc., Chicago, IL, EE. UU.). Como resultado del estudio, cuando se examinaron los datos sobre los polimorfismos rs1805086 y rs1805065 del gen MSTN respectivamente, se descubrió que el genotipo MSTN 153KK era 100,0 % dominante en luchadores de brazos nacionales (n = 24) y aficionados (n = 21) , y era 94,12 % dominante en personas sedentarias. El genotipo KR se observó en el 5,88 % de las personas sedentarias. Los datos del otro polimorfismo rs1805065 del gen MSTN mostraron que todos los participantes (n = 45; 100,0 %) eran portadores del genotipo homocigoto normal. Además, tanto para el grupo femenino como para el masculino, se encontró una diferencia estadísticamente significativa en términos de propiedades antropométricas. Se puede concluir que, aunque no hubo una diferencia significativa entre los luchadores de brazos turcos nacionales y aficionados en términos de sus características genéticas MSTN; en términos de propiedades antropométricas, se descubrieron diferencias significativas. Se descubrió que, en estos atletas, no fueron los polimorfismos del gen MSTN sino las propiedades antropométricas las efectivas.

The distal radioulnar joint is not only the main load-bearing joint in the wrist, but also the pivot of the rotation of the forearm. It is one of the most important and unique joints in the body. Maintaining the stability of the distal radioulnar joint is very important for our daily life. The tissue to stabilize the distal radioulnar joint includes bone structures and soft tissue structures. Although the contribution of soft tissue structures to its stability is far exceeding that of bone structures, the influence of abnormal bone structure on the distal radioulnar joint cannot be ignored. By reviewing the relevant literatures, this article divides the bone structural abnormalities into congenital and acquired bone structural abnormalities. The effects of congenital and acquiredbone structural abnormalities on the distal radioulnar joint stability are analysized and collated in this article, and its clinical symptoms, clinical grading, clinical treatments are also summerized. The problems of distal radioulnar joint instability in clinical practicing and its future researching directions are briefly described in order to provide some suggestions for future clinical applications.

Repetitive transcranial magnetic stimulation (rTMS) has been known to improve the motor function through modulation of excitability in the cerebral cortex. However, most studies with rTMS were limited to post-stroke patients with mild to moderate motor impairments. The effect of rTMS on severe upper-limb motor impairment remains unclear. Therefore, this study investigated the effects of rTMS on the upper extremity function in post-stroke patients with severe upper-limb motor impairment. Subjects were divided into 3 groups, low-, high-frequency rTMS and control group were received stimulation 10 times for 2 weeks. The motor scale of Fugl-Meyer Assessment (FMA) and cortical excitability on the unaffected hemisphere were measured before and after performing 10 rTMS sessions. The motor scale of upper extremity FMA (UE-FMA) and shoulder component of the UE-FMA were significantly improved in both low- and high-frequency rTMS groups. However, no significant improvement was observed in the wrist and hand components. No significant differences were noted in low- and high-frequency rTMS groups. The amplitude of motor evoked potential on the unaffected hemisphere showed a significant decrease in the low- and high-frequency stimulation groups. rTMS may be helpful in improving upper extremity motor function even in post-stroke patients with severe upper-limb motor impairment.

A systematic search was conducted and relevant studies that evaluated the influence of osteoporosis medications (bisphosphonates [BPs], denosumab, selective estrogen receptor modulators [SERMs], recombinant human parathyroid hormone teriparatide [TPTD], and strontium ranelate [SrR]) on wrist, hip, and spine fracture healing, were selected. BPs administration did not influence fracture healing and clinical outcomes after distal radius fracture (DRF). Similar results were observed in hip fracture, but evidence is lacking for spine fracture. Denosumab did not delay the non-vertebral fractures healing in one well-designed study. No studies evaluated the effect of SERMs on fracture healing in humans. One study reported shorter fracture healing times in TPTD treated DRF patients, which was not clinically meaningful. In hip fracture, recent studies reported better pain and functional outcomes in TPTD treated patients. However, in spine fracture, recent studies found no significant differences in fracture stability between TPTD treated patients and controls. Evidence is lacking for SrR, but it did not influence wrist fracture healing in one study. In comparisons between TPTD and BPs, fracture healing and physical scores were not significantly different in hip fracture by 1 study. In spine fracture, controversy exists for the role of each medication to the fracture stability, but several studies reported that fracture site pain was better in TPTD treated patients than BPs treated patients. Considering no clinical data of negative fracture healing of the antiresorptive medication and the danger of subsequent fracture after initial osteoporotic fracture, there is no evidence to delay initiation of osteoporosis medications after fracture.

In terms of management of Paget's disease of bone (PDB), early diagnosis and proper management achieving remission is essential with lifelong specialist follow-up. We present the case of a 40-year-old woman with PDB affecting mainly the distal extremities (ankle and wrist). The patient visited our hospital in 2012 with heel pain. Plain radiography revealed osteoporosis, and a bone scan revealed hot uptake. Initial laboratory investigations showed normal serum calcium, 25-hydroxy-vitamin D, and parathyroid hormone levels; however, osteocalcin, C-terminal telopeptide of type I collagen, and bone alkaline phosphatase levels were elevated. A bone mineral density scan showed T- and Z-scores of −2.5 and −2.7, respectively, and bisphosphonate treatment was initiated. Biopsy performed on the calcaneal lateral wall revealed inconclusive findings. Follow-up biopsy on the left distal radius was performed 7 years later to investigate wrist pain, and this examination led to a final diagnosis as PDB. We suggest inconclusive biopsy result during the early phase of PDB and highly recommend follow-up evaluation in osteoporosis with atypical behavior.

Distal ulnar fractures are commonly accompanied by distal radial fractures, and several treatment options such as plate osteosynthesis and pinning with Kirschner's wires are used. In this study, we present a technique using headless compression screws to achieve bony union of distal ulnar fractures. From November 2016 to November 2018, we treated 11 patients with distal ulnar fractures combined with distal radial fractures with headless compression screws (DePuy Synthes). Patients were instructed to maintain a short-arm splint for less than two weeks after the treatment. The mean time to bony union was 6.5 weeks, mean Quick Disabilities of the Arm, Shoulder, and Hand score was 14.6 points, and mean visual analog scale score was 1.09 points. Full range of motion was possible in all directions after surgery and no specific complications were observed. The suggested technique allows minimal incision and minimally invasive intramedullary fixation and can promote bony union in a simple way without specific complications.

BACKGROUND: Immune cells express the vitamin (vit) D receptor, and vit D is a potent immune-modulator. A negative correlation between serum vit D levels and rheumatoid arthritis (RA) disease activity has been reported. Therefore, we aimed to investigate if the sufficient serum vit D level is helpful to control disease activity in RA patients treated with interleukin (IL)-6 receptor antibody tocilizumab.METHODS: RA patients taking tocilizumab were enrolled, and data were collected retrospectively. Disease activity scores (DAS) 28, serum vit D levels, modified Sharp scores of hand X-ray at the time of tocilizumab initiation, and follow-up data were analysed. Peripheral blood mononuclear cells were differentiated into T-helper (Th) 17 or osteoclasts in the presence of various concentrations of tocilizumab and/or 1,25(OH)₂D. Th17 proportions were analysed by fluorescence-activated cell sorting. Supernatant cytokine levels were determined by enzyme-linked immunosorbent assay.RESULTS: Among 98 RA patients taking tocilizumab, 34 (34.7%) had sufficient serum 25(OH)D levels (≥ 30 ng/mL) when tocilizumab was initiated. At 24 weeks, vit D sufficient patients had greater DAS28 reduction (64.6% ± 15.5% vs. 52.7% ± 20.7%, P = 0.004), and lower disease activity (91.2% vs. 70.3%, P = 0.018) or remission (82.4% vs. 57.8%, P = 0.014). These differences in DAS28 reduction and the proportion of patients with remission persisted at 48 weeks. However, there was no significant difference in hand and wrist erosion progression. In vitro, tocilizumab and 1,25(OH)₂D treatment synergistically suppressed IL-17 production and osteoclastogenesis.CONCLUSION: RA patients treated with IL-6 antibody show a better response when they have sufficient serum vit D. Tocilizumab and 1,25(OH)₂D synergistically suppress IL-17 production and osteoclast differentiation in RA patients.

La osteonecrosis del semilunar o enfermedad de Kienböck es un cuadro progresivo y debilitante que puede llevar al dolor crónico y la pérdida de la función. Pese a que se conoce hace más de 100 años, la etiología todavía es incierta, si bien se la ha relaciona-do con factores mecánicos, vasculares y traumáticos. Su evolución natural está pobremente definida y los hallazgos radiográficos no siempre se correlacionan con los hallazgos clínicos. Se han logrado avances para identificar y entender la progresión del pro-ceso avascular y sus efectos nocivos sobre la mecánica de la muñeca. El tratamiento inicial es no quirúrgico. El perfeccionamiento de la técnica quirúrgica utilizando injertos óseos vascularizados de radio distal puede mejorar los resultados en los pacientes que cursan etapas tempranas de la enfermedad, aunque resta mucho trabajo para determinar si este tratamiento quirúrgico re-presenta una mejor opción que los tratamientos tradicionales. Reportes recientes de resultados a largo plazo de la osteotomía de acortamiento del radio para estadios tempranos de la enfermedad y la resección de la primera fila del carpo para estadios avan-zados revelan que estos procedimientos son una opción válida para el tratamiento a largo plazo de este cuadro de difícil manejo.

Osteonecrosis of the lunate or Kienböck's disease is a progressive, debilitating condition that can lead to chronic pain and function loss. Despite it was identified almost 100 years ago, the etiology remains unknown, although mechanical, vascular, and traumatic factors have been associated. The natural history of Kienböck's disease is poorly defined, and the radiographic findings do not always correlate with the clinical findings. There has been some progress in identifying and understanding the progression of the avascular process and its deleterious effects on wrist mechanics. Initial treatment is conservative. Improvement in surgical tech-niques with vascularized bone grafts from the distal radius may lead to an outcome improvement for patients in the early stages of disease. However, more research is still needed to determine whether this surgical treatment represents an improvement over conventional treatment alternatives. Recent reports of long-term outcomes for radial shortening osteotomy in osteonecrosis early stage patients and for proximal row carpectomy (PRC) in advanced Kienböck's disease patients reveal that these procedures provide reliable options for the long-term management of this challenging condition.

El músculo extensor radial largo del carpo (MERLC) es un músculo localizado en el compartimiento posterior (extensor-supinador) del antebrazo y tiene gran importancia en el cierre del puño. Hay pocos estudios biométricos con respecto al punto de origen de sus ramos de inervación, así como sobre la distribución de los mismos. Basado en lo anterior, se estudiaron 30 miembros superiores, formolizados, de individuos adultos Brasileños, de la Facultad de Medicina de la Universidad Estadual de Ciencias da Saúde de Alagoas, Maceió, Brasil. Luego de localizar el nervio, se midió la distancia entre el origen del ramo primario y el de los puntos motores respecto a la línea biepicondílea (LBE), los cuales fueron visualizados y disecados utilizando una lupa. El nervio en cuestión, se observó a nivel del brazo o proximal a LBE en 28 casos (93 %) y los 2 restantes a nivel de esta línea (7 %). Los ramos para el ERLC se originaron a partir del nervio radial, observando un ramo primario en 20 miembros (80 %), y en los restantes 10 (20 %) se observaron 2 ramos primarios, promediando 1,3 ramos (DS 0,5). El origen más proximal del primer ramo primario (RP) independiente de que si existían 1 o 2 fue en promedio 3 cm (DS 1,0) proximal a LBE. El PM más distal, se ubicó distal a LBE en 24 casos con un promedio de 1,9 cm (DS 1,0); localización a nivel de LBE en 3 casos. Sólo en 3 casos el PM más distal se encontró proximal a LBE, en un promedio de 0,8 cm (DS 0,5). La distribución de puntos motores fue variable, ya que muchas veces los RP se bifurcaban en ramos secundarios y éstos, a su vez se dividían hasta 6 veces en ramos terciarios que penetraban en el músculo. El conocimiento biométrico del origen del nervio del MERLC, así como su distribución, es un aporte importante al área anátomo-quirúrgica, así como, su utilización en bloqueos nerviosos, transferencias nerviosas y zonas de ubicación de electrodos con propósitos de estimulación eléctrica en pacientes que necesiten rehabilitar la acción de musculatura extensora radial lesionada.

The extensor carpi radialis longus muscle (ECRLm) is located in the posterior compartment (extensorsupinator) of the forearm and has great importance in the closure of the hand. There are few biometric studies with respect to the point of origin of their branches of innervation, as well as on the distribution of them. For this study, 30 upper limbs, formalized, of Brazilian adult individuals were used, from the Faculty of Medicine of the Universidad Estadual de Ciencias da Saúde de Alagoas, Maceió, Brazil. After locating the nerve, we measured the distance between the origin of the primary branch and that of the motor points with respect to biepicondilar line (BEl), which were visualized and dissected using a magnifying glass. The nerve in question was observed at the level of the arm or proximal to BEl in 28 cases (93 %) and the remaining 2 at the level of this line (7 %). The branches for the ECRLm originated from the radial nerve, observing a primary branch in 20 limbs (80 %), and in the remaining 10 (20 %) two primary branches were observed, averaging 1.3 branches (SD 0.5). The most proximal origin of the first primary branch (PB) independent of whether there was 1 or 2 was on average 3 cm (SD 1.0) proximal to BEl. The most distal MP was distal to BEl in 24 cases with an average of 1.9 cm (SD 1.0); location at the BEl level in 3 cases. Only in 3 cases was the most distal MP found proximal to BEl, an average of 0.8 cm (SD 0.5). The distribution of motor points was variable, since many times the PB bifurcated into secondary branches and these, in turn, could divide up to 6 times in tertiary branches that penetrated in the muscle. The biometric knowledge of the origin of the nerve of the ECRLm, as well as its distribution, is an important contribution to the anatomo-surgical area, as well as its use in nerve blocks, nerve transfers and electrode placement areas for purposes of electrical stimulation in patients they need to rehabilitate the action of injured radial extensor musculature.
