Análise epidemiológica das fraturas de mão em um hospital terciário / Epidemiological analysis of hand fractures in a tertiary hospital

Introdução: O trauma de mão constitui uma epidemia, ocorrendo por diversos fatores, como acidentes de trabalho e violência urbana. Isso gera um impacto significativo por ser uma unidade anatômica vulnerável e importante na realização de atividades cotidianas e para o trabalho. Desse modo, faz-se necessária uma avaliação epidemiológica mais aprofundada no que tange, sobretudo, às fraturas de mãos, entendendo sua elevada morbidade. Método: Estudo descritivo e retrospectivo, feito por análise de prontuários de pacientes conduzidos em um hospital terciário no período de janeiro de 2018 a dezembro de 2020. Resultados: Participaram do estudo 290 pacientes, sendo 85,7% do sexo masculino e 14,3% do sexo feminino. 138 indivíduos tinham entre 20 e 39 anos, representando um total de 47,6%. 51,6% eram do interior do estado do Ceará e 48,4% eram da capital. O principal mecanismo de trauma associado às fraturas foram os acidentes de trânsito (36,4%), seguidos por acidentes de trabalho (26,9%) e ferimentos por arma de fogo (14%). Em relação aos ossos fraturados, houve uma acentuada prevalência do acometimento das falangeanas, em todas as faixas etárias, representando 210 pacientes (72,4%). Conclusão: O presente estudo corrobora com os dados presentes na literatura. Desse modo, é evidenciada a repetição de prevalência de faixa etária, principais mecanismos de trauma envolvidos, bem como ossos acometidos nas fraturas de mão.

Introduction: Hand trauma is an epidemic occurring due to several factors, such as work accidents and urban violence. This significantly impacts it as it is a vulnerable and important anatomical unit for daily activities and work. Therefore, a more in-depth epidemiological assessment is necessary regarding hand fractures and understanding their high morbidity. Method: A descriptive and retrospective study was conducted by analyzing the medical records of patients treated in a tertiary hospital from January 2018 to December 2020. Results: 290 patients participated in the study, 85.7% male and 14.3 % female. One hundred thirty-eight individuals were between 20 and 39 years old, representing 47.6%. 51.6% were from the interior of the state of Ceará, and 48.4% were from the capital. The main trauma mechanism associated with fractures was traffic accidents (36.4%), followed by work accidents (26.9%) and firearm injuries (14%). Concerning fractured bones, there was a marked prevalence of phalangeal involvement in all age groups, representing 210 patients (72.4%). Conclusion: The present study corroborates the data present in the literature. In this way, the repetition of the prevalence of age group, main trauma mechanisms involved, as well as bones affected by hand fractures is evidenced.

The posterior interosseous nerve at the proximal forearm: anatomical study and clinical correlation / El nervio interóseo posterior en el antebrazo proximal: estudio anatómico y correlación clínica

SUMMARY: The deep branch of the radial nerve (DBRN) runs through the radial tunnel, which is a muscle-aponeurotic structure that extends from the humeral lateral epicondyle to the distal margin of the supinator muscle (SM). The Posterior Interosseous Nerve (PIN) originates as a direct continuation of the DBRN as it emerges from the SM and supplies most of the muscles of the posterior compartment of the forearm. The PIN can be affected by compressive neuropathies, especially at the "Arcade of Frohse". Its preservation is of special interest in surgical approaches to proximal radius fractures and in compressive syndromes release, for which surgeons must have an adequate anatomical knowledge of its course. This descriptive cross-sectional study evaluated 40 upper limbs of fresh cadavers. The diameters of the DBRN, the length of the radial tunnel, and the distances to the supinator arch, PIN emergence and PIN bifurcation were measured. The deep branch of the radial nerve (DBRN) has a course of 23.8 ± 3.7 mm from its origin to the supinator arch, presenting a diameter of 2.2 ± 0.3 mm at that level. The length of the radial tunnel was 42.2 ± 4 mm. The PIN originated 70.7 ± 3.5 mm distal to the lateral epicondyle. Type I corresponds to the division of the PIN during its journey through the radial tunnel, presenting in 35 % of cases, and Type II corresponds to the division of the PIN distal to its emergence from the radial tunnel presenting in the remaining 65 %. This study enriches the knowledge of the PIN and provides useful reference information on a Latin American mestizo sample. We propose the division pattern of the PIN into two types. Future studies may use this classification not only as a qualitative variable, but also include quantitative morphometric measurements.

El ramo profundo del nervio radial (RPNR) discurre por el túnel radial, que es una estructura músculo- aponeurótica que se extiende desde el epicóndilo lateral del húmero humeral hasta el margen distal del músculo supinador (MS). El nervio interóseo Posterior (NIP) se origina como una continuación directa del RPNR cuando emerge del MS e inerva la mayoría de los músculos del compartimiento posterior del antebrazo. El NIP puede verse afectado por neuropatías compresivas, especialmente en la "Arcada de Frohse". Su conservación es de especial interés en los abordajes quirúrgicos de las fracturas proximales de radio y en la liberación de síndromes compresivos, para lo cual los cirujanos deben tener un adecuado conocimiento anatómico de su curso. Este estudio descriptivo transversal evaluó 40 miembros superiores de cadáveres frescos. Se midieron los diámetros de la RPNR, la longitud del túnel radial y las distancias al arco supinador, la emergencia del NIP y la bifurcación del NIP. El RPNR tenía un recorrido de 23,8 ± 3,7 mm desde su origen hasta el arco supinador, presentando un diámetro de 2,2 ± 0,3 mm a ese nivel. La longitud del túnel radial fue de 42,2 ± 4 mm. El NIP se originó 70,7 ± 3,5 mm distal al epicóndilo lateral. El tipo I corresponde a la división del NIP durante su recorrido por el túnel radial presentándose en el 35 % de los casos, y el tipo II corresponde a la división del NIP distal a su salida del túnel radial presentándose en el 65 % restante. Este estudio enriquece el conocimiento del NIP y proporciona información de referencia útil sobre una muestra de mestizos latinoamericanos. Proponemos el patrón de división del NIP en dos tipos. Futuros estudios pueden utilizar esta clasificación no solo como una variable cualitativa, sino también incluir medidas morfométricas cuantitativas.

Serratus anterior muscle flap for reconstruction of extremity injuries / Retalho do músculo serrátil anterior para reconstrução de lesões em extremidades

ABSTRACT Objective: To report the use of the serratus anterior free tissue transfer in the treatment of traumatic injuries. Methods: Twenty-six free flaps or serratus pedicled flaps were performed for reconstruction of traumatic extremity injuries. Results: Complete flap survival was recorded in 20 limbs and 3 patients had circulatory complications. Even with the review of vascular anastomoses, partial flap necrosis could not be prevented and required a skin graft after debridement in the necrotic area. Another flap also required reexploration as a result of heavy congestion due to impaired venous return. Superficial wound infection was found in three patients and treated with conservative measures. Regarding the donor area, seroma formation was found in 8 cases; drainage was necessary in 2, and the others were resolved spontaneously. In 2, bruises formed and were later drained. In 1 limb there was long thoracic nerve injury and scapular winging. Conclusion: According to this study, the serratus anterior muscle flap is an excellent tool for treating small complex lesions in the extremities. Level of Evidence IV; Case series .

RESUMO Objetivo: Relatar o uso da transferência de retalho livre do serrátil anterior no tratamento de lesões traumáticas. Métodos: Vinte e seis retalhos livres ou pediculados do serrátil anterior foram realizados para reconstrução de lesões traumáticas de extremidades. Resultados: A sobrevida completa do retalho foi registrada em 20 membros e 3 pacientes tiveram complicações circulatórias. Mesmo com a revisão das anastomoses vasculares, a necrose parcial do retalho não pôde ser prevenida e exigiu enxerto de pele após desbridamento da área necrótica. Outro retalho também necessitou reexploração em decorrência de forte congestão por dificuldade de retorno venoso. Infecção de ferida superficial foi encontrada em três pacientes, tratados com medidas conservadoras. Em relação à área doadora, a formação de seroma foi encontrada em 8 casos; em 2 foi necessária drenagem e os demais foram resolvidos espontaneamente. Em 2 houve formação de hematomas, que foram drenados. Em um membro havia lesão longa do nervo torácico e deformidade do tipo escapula alada. Conclusão: De acordo com este estudo, o retalho do músculo serrátil anterior é uma excelente ferramenta para o tratamento de lesões complexas e pouco extensas nas extremidades. Nível de Evidência IV; Série de casos .

An extraordinary journey of courage, commitment and solidarity:the history and the development of hand surgery in China / 中华创伤杂志

The development of hand surgery in China began from the 1950s. Although it started late compared with the Western countries，it has developed rapidly. It has made remarkable achievements，such as the world's first severed finger replantation，the first severed arm replantation，the first second toe transplantation for thumb reconstruction，and the first contralateral C 7 nerve root transfer，etc. It has been gradually popularized，developed and expanded in whole China，and has now steadily moved to the world and is gradually surpassing the international standards. On the 100th anniversary of the founding of the Communist Party of China，the authors review the history and achievements in hand surgery to show the spirit of hard struggle，persistent development and continuous progress of Chinese hand surgeons，to forge ahead the spirit of persistance，unity，inheritance and innovation for the development of hand surgery in China.

Efficacy of free superficial circumflex iliac artery flap combined with anterolateral thigh flap for repairing large skin defect of the hand / 中华创伤杂志

Objective:To investigate the clinical effect of free superficial circumflex iliac artery flap combined with anterolateral thigh flap in repairing large skin defect of the hand.Methods:A retrospective case series study was conducted to analyze the clinical data of 9 patients with large skin defect of the hand admitted to Ningbo No.6 Hospital from January 2016 to December 2019，including 7 males and 2 females，aged 31-63 years［（45.3±5.6）years］. The area of skin defect reanged from 20 cm×15 cm to 25 cm×20 cm. One side of the superficial circumflex iliac artery flap and the contralateral anterolateral thigh flap were used for repair. Both recipient and donor sites were sutured at the first stage. The ilioinguinal region and thigh donor region were sutured directly. The area of superficial circumflex iliac artery flap was from 19 cm×6 cm to 23 cm ×10 cm and that of anterolateral thigh flap was 19 cm×9 cm to 23 cm×8 cm. The flap survival，healing of donor and recipient area and complications were observed. At 1，6 and 12 months after operation，the function of the flap was evaluated by the late functional evaluation criteria of the flap，hand function by the upper limb functional evaluation criteria of the Chinese Medical Association，and scar condition of the donor site by Vancouver Scar Scale（VVS）. At the last follow-up，the color，elasticity，appearance and scar of the donor site were observed.Results:All patients were followed up for 6-18 months［（12.5±2.3）months］. All flaps survived successfully. All patients achieved donor-site healing at the first stage，except that one patient experienced incision dehiscence in the thigh donor site after operation and healed after the second stage suture. The texture and appearance of the flaps were good. The flap in 5 patients was obviously bloated. Therefore，the secondary skin flap repair was selected，and the appearance was significantly improved after operation. Scores for function of the flap and the hand were improved over time（ P<0.05）. At 12 months after operation，the function of the flap was excellent in 3 patients，good in 4 and fair in 2，with the excellent and good rate of 78%；the result of hand function was excellent in 3 patients，good in 3 and fair in 3，with the excellent and good rate of 67%. The VVS score of the donor site decreased from（9.7±1.3）points at postoperative 1 month to（5.7±0.9）points at postoperative 6 months and（3.4±0.8）points at postoperative 12 months（ P<0.05）. At the latest follow-up，the color and elasticity of the flap was similar to that of the surrounding skin tissue，only with slight bloating；the scar of the donor site was small. Conclusions:The free superficial circumflex iliac artery flap combined with anterolateral thigh flap can cover large skin defect of the hand at one time，with good appearance and texture of the flap. The appearance and function of the wounded hand are good after operation，leaving only linear scar in the donor site.

Efficacy of CT angiography combined with three-dimensional modeling-assisted design of superficial peroneal artery perforator flap for reconstruction of traumatic hand wound / 中华创伤杂志

Objective:To investigate the effectiveness of CT angiography (CTA) combined with three-dimensional modeling-assisted design of superficial peroneal artery perforator flap for reconstruction of traumatic hand wound.Methods:A retrospective case series study was conducted to analyze the clinical data of 15 patients with hand injury admitted to 920th Hospital of Joint Logistic Support Force of PLA from January 2016 to December 2019. There were 11 males and 4 females, aged 19-51 years [(27.8±8.1)years]. All patients had soft tissue defect of the hand with exposed bone or tendon, and the defect area ranged from 2.0 cm×1.0 cm to 6.0 cm×4.0 cm. All patients underwent CTA of the abdominal aorta to dorsalis pedis artery before surgery. The three-dimensional models of bones, blood vessels, skin and other tissues were reconstructed by Mimics 20.0 software. The location, diameter and length of the superficial peroneal artery perforator vessels were accurately measured, and the perforator flap was designed according to the shape and size of the defect, then the resection of flap was simulated. During the operation, the superficial peroneal artery perforator flap was removed and transplanted to repair the defect according to the design. The location, diameter and length of perforator vessels were measured intraoperatively and compared with the preoperative modeling measurement. The operation time and intraoperative blood loss were recorded. The survival of the flap and healing of the donor site were observed after operation. The function of the affected limb was evaluated according to the upper limb function evaluation standard of Chinese Medical Association before and 3 months after surgery. The appearance, sensation and motion of the donor site were observed 3 months after surgery.Results:The origin and course of superficial peroneal artery perforator vessels could be clarified preoperatively based on the three-dimensional model. There was no significant difference in the location, diameter and length of perforator vessels between the pre- and intra-operative measurements ( P>0.05). All patients were followed up for 6-20 months [(12.2±3.8)months]. The operation duration was 50-125 minutes [(91.2±10.4)minutes], with blood loss of 150-450 ml [(364.1±44.7)ml]. The partial epidermal necrosis occurred in 2 patients after surgery, which gradually healed after dressing change, and other flaps survived smoothly. All donor sites could be sutured directly, and all incisions healed by first intention. According to the upper limb function evaluation standard of the Chinese Medical Association, the affected limb scored (76.4±9.7)points 3 months after surgery, higher than the preoperative score of (48.2±10.1)points ( P<0.05). The results were excellent in 8 patients, good in 6 and fair in 1, with the excellent and good rate of 93%. All patients had slight scar growth in donor sites and showed no obvious abnormalities in the sensation of foot dorsum and donor sites, with normal walking gait. Conclusion:CT angiography combined with three-dimensional modeling can accurately locate the perforating vessels, realize the individualized and precise design of the superficial peroneal artery perforator flap, and assist in the rapid and accurate flap resection, and hence promote wound healing and functional recovery of the hand.

ABSTRACT Background: Heberprot P is a therapy that contributes to the repairing of damaged tissues. Its use in orthopedic injuries of the upper limbs is very recent and of little publication. Objective: To describe the evolution of a patient with a serious injury to the back of the right hand in which the Heberprot P was used, followed by a pedicle graft. Case report: Patient who suffered an accident with a serious right hand injury. Clinical and imaging diagnosis was made with skin loss, subcutaneous cellular tissue and fracture of the fourth and fifth metacarpals, a surgical procedure was applied. It evolved torpidly with deep infection, loss of extensor tendons and bone exposure, it was decided to start treatment with Heberprot P to stimulate granulation tissue; 21 days later, the bone structures were covered, the tendons and skin coverage were operated with a bipedicular graft to the abdomen with a favorable evolution. The patient returned to her social and work activity at 10 months. Conclusions: Heberprot P accelerated tissue healing, associated with remote flaps, facilitated a satisfactory evolution and avoided amputation, decreased hospital stay, and also favored return to social and work life.

A descriptive study of patterns of traumatic hand injury cases in a tertiary care hospital

Background: All patients who presented to the emergency and trauma with a clinical evidence of hand injury were assessed based on the history and examination, mechanism of injury, common patterns of the injuries, management of the injuries and their functional outcome. The aim and objective were to study the mode, pattern, management and early outcome of hand injury cases attending Department of Emergency Medicine and trauma.Methods: This was a hospital based descriptive study, of patients presenting with hand injuries to the emergency department. The management plan was formulated and the outcomes of the treatment were assessed by limb function loss and Quick DASH 9 score.Results: Majority of our study population belonged to 16 to 35 years age group comprising of mostly males. Most of the incidents occurred within 50 km from our hospital. The mean duration to arrival at our hospital from site of injury was 2.71±2.61 hours. Road traffic accident in males and thermal burns in females were common. Fractures to phalanges of index and middle fingers were the most common type of injury. The average calculated Quick DASH 9 score was found to be 51.24±9.89.Conclusions: Hand injuries were found to be more prevalent in lower socioeconomic strata of the society with education status and occupation as major risk factors. Increased awareness and better implementation of traffic rules and better safety measures at workplace environment are the need of the hour to decrease the burden of hand injury.

Prospective study of hand injuries in Government Royapettah Hospital

Background: Hands often get injured and can be incapacitating the patient if care is not given properly. Injury to hand leads to loss of function as well as deformity of body image which can cause a lot of psychological consequences. The objective of the study was to analyze the pattern of hand injuries encountered and to compare the functional recovery at first and third month after appropriate management.Methods: Totally 150 consecutive patients presenting with history of injury to hand or hands following road traffic accidents, industrial accidents, assault etc. are selected based on non-probability sampling method appropriate preliminary radiological and blood investigations were done and appropriate management was carried out to analyze the final outcomes. Results: Out of 150 cases in our study fingers contributed 121 (80.6%) of cases followed by palmar and dorsum of hand in about 26 cases (17.3%), wrist and forearm injuries contributing about 3 cases (2%). In fingers most of injuries occurred in third finger 35 cases (23.3%) followed by F2-28 (18.6%), F4-21 (14%), F5-20 (13.3%), thumb-17 (11.3%). Most injuries were in the left hand. required secondary procedures.Conclusions: Early presentation of patients and unlikely prehospital involvement of traditional bone setters reflect the great importance attached to hand injuries. Promotion of safety measures in the workplace and homes and prevention of road traffic crashes would help in reducing the incidence of hand injuries.

Wrist Arthroscopy in Athletes / Artroscopia de punho em atletas

Abstract Arthroscopy is a surgical technique whose indication for wrist injuries has grown in recent years. Athletes are subject to traumatic injury to the wrist due to training overload or the intensity of the activity during competition. The need of a quick return to sports practice makes arthroscopy a very useful minimally invasive technique in these situations. The authors present indications of sports-related injuries to the wrist that can be treated by arthroscopy. A literature review is also presented.

Resumo A artroscopia é uma técnica cirúrgica que tem sido cada vez mais usada para a abordagem de lesões no punho. Atletas estão sujeitos a lesões traumáticas no punho devido à sobrecarga de treinamento ou à intensidade da atividade em competição. A necessidade de retornar o mais breve possível à pratica esportiva faz da artroscopia uma técnica minimamente invasiva muito útil nessas situações. Os autores apresentam as principais indicações de tratamento de lesões esportivas por artroscopia. Foi feita uma revisão da literatura.

Analysis of comprehensive intervention effect of post-traumatic stress disorder in patients with acute hand injury / 中国基层医药

Objective@#To analyze the comprehensive intervention effect of post-traumatic stress disorder (PTSD) in patients with acute hand injury, and its correlation with hand function recovery.@*Methods@#A total of 120 patients with hand trauma admitted to Wenzhou Hospital of Traditional Chinese Medicine from April 2016 to April 2018 were selected.The patients were randomly divided into observation group (60 cases) and control group (60 cases) according to the digital table.The observation group received routine treatment and comprehensive intervention.The control group was given routine treatment.The PDST scale (CAPS), depression self-rating scale (SDS) and Hamilton anxiety scale (HAMA) rating scale used by clinicians were used to assess the psychological status, depression and anxiety of patients with PTSD, and to evaluate the upper limb function of patients.@*Results@#After intervention, the scores of CAPS, SDS and HAMA in the control group were (24.51±8.43)points, (50.61±7.59)points and (10.63±2.11)points, respectively, which were significantly higher than those in the observation group[(16.53±7.62)points, (40.26±4.18)points, (8.24±1.86)points](t=5.61, 5.59, 4.73, all P<0.05). The CAPS, SDS and HAMA scores of the two groups were significantly improved compared with before intervention (t=4.11, 5.04, 3.98, 5.18, 3.86, 4.72, all P<0.05). After intervention, the upper limb function scale (DASH) scores of the observation group and the control group were (89.27±6.08)points and (82.11±7.92)points, respectively.The DASH scores of the two groups were significantly higher than those before intervention (t=6.14, 5.28, all P<0.05). The DASH score of the observation group was superior to the control group (t=3.96, P<0.05). The DASH score of patients with hand injury was negatively correlated with CAPS score and SDS score (r=-0.362, -0.425, P=0.012, 0.008).@*Conclusion@#Comprehensive intervention for PTSD in patients with acute hand injury can significantly improve the degree of depression and anxiety, and improve the upper limb function of patients.
