摘要
Bone age is an important index objectively reflecting the growth and development level of children and adolescents, as well as predicting growth potential.It plays a key role in various complicated situations involving clinical medicine, forensic and sports science.The wrist and the extremitas sternalis of clavicle are the most common sites for bone age assessment.Several techniques are available to evaluate bone age, including X-ray plain radiography, ultrasound, CT and magnetic resonance imaging.The accuracy and efficiency of bone age assessment have been continuously improved from traditional manual assessment to automatic assessment.This paper mainly reviews the advances in the techniques and methods for bone age assessment of the wrist and the extremitas sternalis of clavicle.

BACKGROUND:With the application and development of 3D printing technology in medicine,orthopedic internal fixation surgery has become precise and individualized.The equal-scale fracture model obtained by 3D printing technology was simulated and planned before surgery,realizing the leap from traditional 2D images to more vivid and detailed three-dimensional objects.It allows the surgeon to understand the fracture type in advance and rehearse the reduction sequence,so as to realize the individualized implementation of fracture surgery,optimize the surgical process,bring better postoperative recovery and less surgical complications. OBJECTIVE:To compare clinical efficacy of three 3D printed models combined with computerized virtual repositioning technology to assist incision reduction bone plate internal fixation and traditional incision reduction bone plate internal fixation in the treatment of Robinson II B2 clavicle fracture. METHODS:Eighty patients with Robinson II B2 clavicle fracture were randomly divided into trial group(n=40)and control group(n=40).In the trial group,three kinds of 3D printing models(affected clavicle fracture model,computer simulation clavicle fracture reduction model,clavicle mirror model of healthy side)combined with computer virtual reduction technology were used for preoperative in vitro surgery rehearsal.Finally,3D printing was used for clavicle mirror model of healthy side to advance bending and select bone plates for internal fixation.In the control group,open reduction plate internal fixation was applied.The time from admission to surgery,intraoperative blood loss,operation time,frequency of fluoroscopy,number of bends of the bone plate,fracture healing time,complications,and visual analog scale score and Constant score before and after surgery were compared between the two groups. RESULTS AND CONCLUSION:The time from admission to operation in the trial group was greater than that in the control group(P<0.05).Operation time,intraoperative fluoroscopy frequency and bending times of the bone plate in the trial group were lower than those in the control group(P<0.05).The trial group had faster fracture healing and fewer complications(P<0.05).There was no significant difference in intraoperative blood loss between the two groups(P>0.05).Constant score of the two groups had an increasing trend with time(F=613.50,P<0.001),but the difference between the groups was not statistically significant(F=0.08,P=0.78),and there was no interaction between the measurement times and the group assignment(F=0.27,P=0.66).The visual analog scale score decreased with time(F=1 149.55,P<0.001),but there was no significant difference between groups(F=0.02,P=0.88),and there was no interaction between the number of measurements and the group assignment(F=1.02,P=0.36).The results show that the use of 3D printed model combined with computer virtual reduction technology for preoperative rehearsal can shorten the operation time,reduce the number of intraoperative fluoroscopy frequency and the times of bone plate bending,and have the advantages of faster fracture healing,fewer complications,and similar functional recovery to the traditional incision reduction bone plate internal fixation.

BACKGROUND:There is no consensus on the optimal bone tunnel position in the lateral clavicle,which guides coracoclavicular ligament reconstruction.Postoperative complications such as enlargement of the lateral clavicle bone tunnel,bone osteolysis,clavicle fracture,and failure of internal fixation are likely to occur.Bone mass density plays an important role in the strength and stability of endophytic fixation.Regional differences in the bone mass density of the distal clavicle should not be overlooked in the repair and reconstruction of acromioclavicular dislocation.Currently,there are no quantitative clinical studies in humans regarding the bone mass density of the distal clavicle. OBJECTIVE:To measure the magnitude of bone mass density in different regions of the distal clavicle by quantitative CT to provide a reference for surgeons to repair and reconstruct the coracoclavicular ligament. METHODS:101 patients undergoing quantitative CT checking in Fuyang People's Hospital Affiliated to Anhui Medical University from October to December 2022 were enrolled,from which 1 616 samples of subdivisional bone mass density of the distal clavicle were measured.For each of the quantitative CT samples,firstly,the distal clavicle was divided medially to laterally into the following four regions:conical nodal region(region A),inter-nodal region(region B),oblique crest region(region C)and distal clavicular region(region D).Secondly,each region was divided into the first half and the second half to determine eight subdivisions,then setting semiautomatic region of interest(ROI)in each subdivision:(ROI A1,A2,B1,B2,C1,C2,D1,and D2).Thirdly,each quantitative CT scan was transferred to the quantitative CT pro analysis workstation,and cancellous bone mass density was measured in the distal clavicle ROI.Finally,the clavicular cortex was avoided when measuring. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in bone mineral density on the different sides of the shoulder(P＞0.05).(2)The analysis of bone mineral density in eight sub-areas of the distal clavicle A1,A2,B1,B2,C1,C2,D1,and D2 showed statistically significant differences(P＜0.05).It could be considered that there were differences in bone mineral density in different areas of the distal clavicle.After pairwise comparison,there was no statistically significant difference in bone mineral density between A1 and A2,D1 and D2,A2 and B1(P＞0.05),and there was a statistically significant difference in bone mineral density between the other sub-areas(P＜0.05).(3)The bone mineral density in the region A2 of the anatomical insertion of the conical ligament was significantly higher than that in the inter-nodular area(region B)(P＜0.05).The bone mineral density in the region A1 was higher than that in the region A2,but the difference was not statistically significant(P＞0.05).The bone mineral density in the region C1 of the anatomical insertion of the trapezium ligament was higher than that in regions C2,D1 and D2,and the bone mineral density in the inter-nodular area(region B)was significantly higher than that in regions C and D(P＜0.05).(4)These results have suggested that there are differences in bone mass density in different regions of the distal clavicle;regional differences in bone mass density in the distal clavicle during repair and reconstruction of acromioclavicular dislocation cannot be ignored.Consideration should be given not only to biomechanical factors but also to the placement of implants or bone tunnels in regions of higher bone mass density,which could improve the strength and stability of implant fixation and reduce the risk of complications such as bone tunnel enlargement,osteolysis,fracture and implant failure.

ABSTRACT Objective: Determine the reliability of three different methods of evaluating bone shortening in displaced midshaft clavicle fractures (DCMF). Method: A cross-sectional analytical study evaluated bone shortening by metric tape (MT), radiography (X-ray), and computed tomography (CT). Twenty-six men had been evaluated and used clavícula not broken as control. The collection of data was of the blind type for three specialists. Differences and reliability were analyzed with the Friedman and Kappa tests and validated with the T-test (CI: 95%; significance index p<0.05; Software "R" version 3.2.2). Results: The MT measurements (control) showed abnormal distribution and significant statistical difference concerning the imaging tests (p=0.000008). There was a similarity between X-ray and CT and Kappa agreement of 0.65. The fractured clavicles presented similar measurements between the three methods (p=0.059), and the T-tests proved that the similarity was caused by chance or possible measurement errors. Conclusion: Measurement by metric tape showed a tendency to overestimate bone shortening. The CT showed more reliable results for the diagnosis; however, the X-ray was sufficient for decision-making by surgeons, and therefore, it is not possible to rule out the importance of this resource for DCMF. Level of Evidence IV; Case-Control Study.
RESUMO Objetivo: Determinar a confiabilidade de três diferentes métodos de avaliação do encurtamento ósseo em fraturas deslocadas do eixo médio da clavícula (FDEMC). Método: Estudo analítico transversal que avaliou o encurtamento ósseo por fita métrica (FM), radiografia (X-Ray) e tomografia computadorizada (TC). Foram avaliados 26 homens utilizando a clavícula não fraturada como controle. A coleta de dados foi do tipo cega por três especialistas. As diferenças e a confiabilidade foram analisadas com os testes de Friedman e Kappa e validados com o teste T (IC:95%; índice de significância p<0,05; Software "R" versão 3.2.2). Resultados: As medidas de FM (controle), apresentaram distribuição anormal e diferença estatísfica significativa em relação aos exames de imagem (p=0,000008). Houve semelhança entre radiografia e TC, concordância Kappa 0,65. As clavículas fraturadas apresentaram medidas semelhantes entre os três métodos (p=0,059) e os testes-T comprovaram que a semelhança foi provocada casualmente ou possíveis erros de medição. Conclusão: A medição por fita métrica apresentou tendência em superestimação do encurtamento ósseo. A TC apresentou resultados mais confiáveis para o diagnóstico, contudo, a radiografia foi suficiente para tomada de decisão dos cirurgiões e por isso, não é possível descartar a importância deste recurso para FDEMC. Nível de Evidência IV; Estudo Caso Controle.
摘要
Abstract Clavicle fracture represents 5% of the fractures in adults. However, segmental clavicle fractures are infrequent and have been understudied in the current literature. Cases have been reported showing adequate results with both surgical and conservative management, and yet, it has not been possible to reach a consensus regarding diagnosis or management of such condition. A patient with a middle and lateral segmental clavicle fracture is reported, after presenting multiple trauma in a road traffic accident, also suffering trauma to the right hemi body, multiple rib segmental fractures and hemothorax. After stabilization, he was taken to surgery for open reduction and internal fixation of the clavicle using a double plate technique, as it has been rarely described in the literature. The functional result was shown to be adequate and satisfactory in the postoperative follow-up. Despite the limited evidence available on the management of this type of pathology, surgical management is a valid option given the risk of non-union. The foregoing is concluded by the potential harm in patient functionality.
Resumo A fratura de clavícula representa 5% das fraturas em adultos. No entanto, as fraturas segmentares da clavícula são infrequentes e pouco estudadas na literatura atual. Há relatos de casos com bons resultados após o tratamento cirúrgico ou conservador, mas não existe consenso quanto ao diagnóstico ou manejo dessas lesões. Relata-se um paciente com fratura segmentar média e lateral da clavícula após politraumatismo em acidente de trânsito. O paciente também apresentava traumatismo em hemicorpo direito, múltiplas fraturas segmentares da costela e do hemotórax. Após estabilização, ele foi encaminhado à cirurgia para redução aberta e fixação interna da clavícula pela técnica de placa dupla, raramente descrita na literatura. O resultado funcional foi considerado satisfatório e adequado no acompanhamento pós-operatório. Apesar das poucas evidências sobre o manejo desse tipo de patologia, o tratamento cirúrgico é uma opção válida devido ao risco de não união, apesar da possível diminuição da funcionalidade do paciente.

Abstract Objective This study aimed to perform an imaging evaluation to prove the existence or not of symmetry between the clavicles of healthy subjects from Curitiba, Paraná, Brazil, and identify potential factors influencing the clavicular length. Method The study analyzed chest computed tomography (CT) scans of 211 patients with no clavicular fracture or malformations (100 women and 111 men). We measured the greatest clavicular diagonal on both sides, and the software automatically generated the maximum distance in millimeters. Relative and absolute frequencies described qualitative variables and mean values; quantitative variables used a 95% confidence interval. Value comparisons employed the student's t-test, and correlations determinations used Pearson's correlation coefficient. The significance level adopted was 5%. Results There was a significant difference between the clavicular length (right clavicle, 143.58 mm; left clavicle, 145.72 mm; p = 0.037), indicating asymmetry. On average, the left clavicle was 3.71 mm larger. Asymmetry was significant for both men and women (p < 0.001). The average difference was 4.13 mm for men and 3.23 mm for women. Seventy-three percent of the sample had < 5 mm of asymmetry, 23.7% had 5 to 10 mm, and 3.3% had > 10 mm of asymmetry. Conclusion The studied population did not present clavicular symmetry. On average, the left clavicle was longer than the right clavicle, with differences of 3.71 mm in the general sample, 3.23 mm in women, and 4.13 mm in men. The only significant factor was gender since men presented longer clavicles and higher differences than women.

Resultados Verificou-se diferença significativa entre o comprimento das clavículas (direita 143.58mm e esquerda 145.72mm, p = 0.037), indicando assimetria. Em média, o lado esquerdo é 3.71mm maior. A assimetria foi significativa tanto para homens quanto para mulheres (p < 0.001). A diferença média foi de 4.13mm para homens e 3.23mm para mulheres. 73% da amostra apresentou <5mm de diferença, enquanto 23.7% apresentou 5-10mm e 3.3% apresentou >10mm de assimetria. Conclusão Não foi possível encontrar simetria nas clavículas da população de Curitiba/PR. Em média, a clavícula esquerda é maior que a direita, com diferenças de 3.71mm na amostra geral, 3.23mm para mulheres e 4.13mm para homens. O único fator significativo foi o sexo, com homens tendo maiores comprimentos claviculares e maiores diferenças em comparação às mulheres.

Case?Presentation Chondromyxoid fibroma (CMF) is a relatively rare bone tumor of cartilaginous origin and it comprises less than 1% of all primary bony tumors. Clavicle is an unusual site of involvement for any bone tumor and may produce diagnostic dilemma. Approximately only 1% of all primary bone tumors may involve the clavicle. The literature on clinical features and outcome of CMF clavicle remains sparse. Conclusion?We present an unusual case of CMF clavicle in which the medial aspect of the clavicle gradually disappeared on radiographs. CMF should be included in the differential diagnoses of disappearing bone disease.
摘要
Objective The Kellinghaus grading method was used to manually read and grade the thin-layer CT of sternal end of clavicle,and a variety of traditional statistical methods as well as machine learning methods were used to construct age estimation models for adolescents and adults in early adulthood,to explore the value of the application of machine learning technology in the study of age estimation of the Han Chinese population in Sichuan.Methods Thin-section CT images of the chest were retrospectively collected from 491 individuals aged 10～30 years,and the collected samples were assigned a reading grade with reference to the Kellinghaus grading method.10%of the xases were randomly selected as the test set,and the remaining data were used as the training set to construct a variety of traditional statistical regression models and machine learning models for estimating the age of adolescents and adults in early adulthood,and the performance of the models was evaluated by using the mean absolute error(MAE).Results The statistical regression model with the best efficacy was the cubic regression model,with an MAE value of 1.34 for males and 1.57 for females;of the three machine learning models,the Random Forest model had the best predictive efficacy for males,with an MAE value of 1.39,and the Support Vector model had the best predictive efficacy for females,with an MAE value of 1.51.Conclusion In the construction of age estimation models for sternal end of clavicle,the machine learning model has a certain improvement in the accuracy of age prediction,but there is no obvious advantage compared with the traditional statistical regression model,and the use of the machine learning method in age estimation based on sternal end of clavicle still needs further exploration.

Objective:To provide anatomic data of the coracoclavicular (CC) ligament attachment regions in Chinese population for anatomic reconstruction of CC ligament to treat acromioclavicular dislocation.Methods:The CC ligaments were first dissected layer by layer out of the bilateral acromioclavicular joint specimens taken from 87 adult cadavers. The CC width and thickness on the attachments of the clavicle and the coracoid process were measured by an electronic digital caliper. The conoid ligament and trapezoid ligament were mapped on the surface of the clavicle and the coracoid process by transecting the ligaments close to their insertions. The distances from the ligament footprint center to the lateral, anterior and posterior margins of the clavicle were measured. The distances from the ligament footprint center to the tip, medial and lateral margin borders of the coracoid process were measured.Results:The distances from the lateral edge of the clavicle to the footprint centers of the conoid and trapezoid ligaments were (35.7 ± 3.4) mm and (21.8 ± 2.7) mm, and the ratio of the distance divided by the clavicular length was 25.5% ± 0.9% and 15.6% ± 1.1%, respectively. The distances from the tip of coracoid to the footprint centers of the conoid and trapezoid ligaments were (35.1 ± 3.2) mm and (29.7 ± 2.9) mm, and the ratio of the distances divided by the coracoidal length was 86.7% ± 1.9% and 73.3% ± 2.1%, respectively.Conclusion:Although the absolute position of the CC ligament attaching to the clavicle and the coracoid process varies greatly among Chinese individuals, the ratio of its relative position to the length and width of the clavicle and the coracoid process is a relatively stable set of data.

OBJECTIVE@#To evaluate the effectiveness of Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures.@*METHODS@#The data of 17 patients with Cho type ⅡC distal clavicular fractures, who were treated with Kirschner wire fixation and coracoclavicular ligament reconstruction with suture anchor between June 2019 and June 2021, was retrospectively analyzed. There were 11 males and 6 females with an average age of 38.7 years (range, 19-72 years). The fractures were caused by falling in 12 cases and traffic accident in 5 cases. All patients had fresh closed fractures. The interval from injury to operation was 1-5 days (mean, 2.6 days). The preoperative injury severity score (ISS) was 6-27 (mean, 10.2). The operation time, intraoperative blood loss, hospital stay, fracture healing, and postoperative complications were analyzed. The shoulder joint function was evaluated by disabilities of the arm, shoulder, and hand (DASH) score and Constant score at last follow-up.@*RESULTS@#All operations were completed successfully. The operation time was 20-50 minutes (mean, 31.6 minutes). The intraoperative blood loss was 30-100 mL (mean, 50.6 mL). The hospital stay was 4-9 days (mean, 5.3 days). All incisions healed by first intention. All patients were followed up 12-16 months (mean, 13 months). All clavicle fractures healed, and the healing time was 8-15 weeks (mean, 11 weeks). No complications such as fracture displacement or nonunion caused by internal fixation failure occurred. During the follow-up, skin irritation caused by the Kirschner wire withdrawal occurred in 3 cases. The Kirschner wires were removed after fracture healing in 17 patients. At last follow-up, the Constant score of shoulder joint was 90-100 (mean, 98.2). The DASH score was 0-10 (mean, 1.5).@*CONCLUSION@#Kirschner wire fixation combined with coracoclavicular ligament reconstruction with suture anchor in the treatment of Cho type ⅡC distal clavicle fractures has less postoperative complications and slight complications. It is convenient to remove the internal fixator. The Kirschner wire does not fix the distal clavicle fracture through the acromion, which has little effect on shoulder joint function and can obtain good effectiveness.

Objective To explore the efficacy of debridement combined with antibiotic-loaded artificial bone in the treatment of clavicular osteomyelitis.Methods The data of 45 patients with clavicle osteomyelitis admitted to Luoyang Orthopedic Hospital(Henan Orthopedic Hospital)in Henan Province from January 2012 to June 2022 were retrospectively analyzed.They were divided into treatment group(n = 24)treated with debridement combined with antibiotic-loaded artificial bone,and control group(n = 21)treated with debridement.We compared the operation time,the duration of drainage tube placement,wound healing time,white blood cells(WBC),C-reactive protein(CRP),and erythrocyte sedimentation rate(ESR)in the two groups.Preoperative visual analog scores(VAS)and VAS 1 month after operation,and preoperative Constant-Murley score(CMS)and CMS 12 months after operation were observed.Infections,recurrence and complications in the two groups were recorded in the follow-up.Results All the 45 patients completed the surgery successfully and were followed up for 13 to 35 months,with an average of(23.53±5.11)months.The operation time and the duration of drainage tube place-ment of the treatment group were longer than those of the control group(P<0.05),and there was no significant difference in the wound healing time(P>0.05);preoperative and 14-day postoperative WBC,CRP,and ESR,VAS 1 month after operation,and CMS 12 months after operation were all significantly improved in the two groups.The differences were all statistically significant(P<0.05),and the CMS of the treatment group was higher than that of the control group(P<0.05).During the follow-up,there were less cases of infection recurrence in the treatment group when compared with that in the control group(2/24,8.33%vs.5/21,23.81%).There were 2 cases of aseptic exudation in the treatment group.There were 1 case of bone defect in the treatment group and 5 in the control group,all of which had healed after the second-stage iliac implantation,and the rest did not have the complication of aseptic exudation,bone defects and pathologic fracture.Conclusion Debridement and antibiotic-loaded artificial bone can effectively control the infection and preserve the shape and function of the clavicle,with a low recurrence rate of postoperative infection,simple surgical operation,and no serious complications.It is wor-thy of clinical promotion.
摘要
@#Introduction: Clavicle fractures in adults are increasingly being treated by surgical fixation following reports of symptomatic non-union, malunion and poor functional outcome with conservative treatment. This has led to a similar trend in the management of clavicle fractures in adolescents. This study aims to evaluate the outcome and complications of non-operatively treated clavicle fractures in adolescents. Materials and methods: This is a retrospective, single institution study on adolescents aged 13-17 years who sustained a closed, isolated clavicle fracture, between 1997- 2015. Clinical records were reviewed for demographic information, injury mode, time to radiographic fracture union, time to re-attainment of full shoulder range of motion (ROM), and time to return to full activities and sports. Complications and fracture-related issues were recorded. Radiographs were analysed for fracture location, displacement and shortening. Results: A total of 115 patients (98 males, 17 females; mean age:13.9 ± 0.89 years) were included for study. 101 (88%) sustained a middle-third fracture while the remainder sustained a lateral-third fracture. A total of 96 (95%) of the middle-third fractures were displaced, and 12 (86%) of the lateral-third fractures were displaced. All displaced fractures in this study had shortening. Sports-related injuries and falls accounted for 68 (59%) and 34 (30%) of the cases respectively. Overall, the mean time to radiographic fracture union was 7.8 ± 4.35 weeks; there were no cases of nonunion. Full shoulder ROM was re-attained in 6.6 ± 3.61 weeks, and full activities and sports was resumed in 11.4 ± 4.69 weeks. There were 5 cases of re-fracture and a single case of intermittent fracture site pain. Conclusion: Clavicle fractures in adolescents can and should be treated non-operatively in the first instance with the expectation of good outcomes in terms of time for fracture union, reattainment of shoulder full range of motion, and return to activities. Surgical stabilisation should be reserved for cases for which there is an absolute indication.

PURPOSE@#Various surgical modalities are available to treat Neer types 2 and 5 unstable fractures of lateral end clavicle but none of them are standardized. Arthroscopic fixation of the displaced lateral end clavicle fractures provides good short-term results but mid- to long-term outcomes are not available. The purpose of this study was to show the mid- to long-term radiological and functional outcomes of these fractures treated arthroscopically by a TightRope device, and to show the complications associated with this procedure.@*METHODS@#A retrospective study was conducted over 2 years from January 2014 to December 2015 with a minimum 5-year follow-up. Active patients aged 18-50 years with acute (less than 3 weeks) displaced fracture of lateral end of the clavicle, with a minimum 5-year follow-up were included in the study. Patients with associated fractures of the proximal humerus, glenoid, scapula and acromioclavicular joint injuries were excluded from the study along with open fractures and neurovascular injuries. The outcomes were assessed by objective (complications and radiographic examination) and subjective criteria (quick disabilities of the arm, shoulder and hand score, the Constant-Murley score and the visual pain analogue scale). The data were analyzed by SPSS version 21.0.@*RESULTS@#Totally, 42 patients were operated during the study period and 37 were available with a minimum 5-year follow-up. Thirty were male and 7 were female with a mean age of 29.5 years and a mean follow-up of 6.1 years. The mean quick disabilities of the arm, shoulder and hand score was 68.2 ± 4.6 preoperatively and 1.27 ± 2.32 at final follow-up (p < 0.001); the mean visual pain analogue scale score was 6.85 ± 2.2 preoperatively and 0.86 ± 1.60 at final follow-up (p < 0.001). The average Constant-Murley score was 93.38 ± 3.25 at the end of the follow-up. There were 2 fixation failures, with established non-union and 3 patients developed radiographic acromioclavicular joint arthritis.@*CONCLUSIONS@#Arthroscopic TightRope fixation of displaced lateral end clavicular fractures provides good radiological and functional outcomes at mid- to long-term follow-up. With the low complication rates and high patient satisfaction, this technique can be considered as a primary option in the surgical treatment of these fractures.

OBJECTIVE@#To summarize the surgical treatment of different proximal clavicle fractures, and discuss the classification of proximal clavicle fractures.@*METHODS@#Total of 24 patients with displaced proximal clavicle fractures were treated from January 2017 to December 2020 including 16 males and 8 females, aged 28 to 66 years old. Among them, 20 cases were fresh fractures and 4 cases were old fractures. According to the Edinburgh classification, 14 cases were type 1B1 fractures and 10 cases were type 1B2 fractures. The different internal fixation methods were selected for internal fixation treatment according to different fracture types.The operation time, blood loss, preoperative and postoperative displacement difference, fracture healing time and Rockwood scoring system were recorded.@*RESULTS@#All patients were followed up for 12 to 24 months. There were no patients with infection or loss of reduction after the operation. Three patients had internal fixation failure after operation, and the internal fixation device was removed. Results The operation time was 30 to 65 min, and the blood loss was 15 to 40 ml. No important nerves, blood vessels, or organs were damaged. The imaging healing time was 3 to 6 months. According to the Rockwood functional score, the total score was (13.50±1.86), pain (2.57±0.50), range of motion (2.78±0.41), muscle strength (2.93±0.28), restricted daily activity (2.85±0.35), subjective results (2.63±0.61);the results were excellent in 20 cases, good in 3 cases, fair in 1 case.@*CONCLUSION@#Proximal clavicular fracture is a type of fracture with low incidence. According to different fracture types, different internal fixation methods and treatment methods can be selected, and satisfactory surgical results can be achieved.

ABSTRACT Clavicle fractures are one of the most common types of bone injuries in adults. Recently, the treatment protocol for these fractures has undergone changes. Objective: To better understand the epidemiological and behavioral profile of these lesions when they require surgical treatment. Methods: This is an analysis of a series of cases. Our sample included individuals undergoing surgical treatment for clavicle fractures. Results: In total, 88 subjects fulfilled the predetermined criteria. Among these, 75 (85.22%) were male; automobile accidents corresponded to the largest etiological group, reaching 48% of prevalence; there was a slight predominance of the right side, totaling 45 cases (51%); most fractures were classified as Allman type I; an infection rate was observed in 1.13% of the cases; and the development of pseudarthrosis was identified in 2.27% of the patients. Conclusion: The incidence of clavicle fracture is higher in young men, mainly caused by car accidents, being mostly located in the middle third. No statistical significance was found between the synthesis material data and the postoperative complication rate, revealing the absence of risk superiority between the different types of surgical approaches used. Level of Evidence IV, Case Series.

ABSTRACT Objective: To evaluate the clinical and radiographic results of the surgical treatment of fractures of the middle third of the clavicle, using the technique of minimally invasive plate osteosynthesis (MIPO) with locking. Methods: Prospective case series, evaluating displaced fractures of the middle third of the clavicle submitted to MIPO with locking, with procedures performed by a single surgeon. Patients were evaluated at 12 months using the University of Los Angeles (UCLA) scale and anteroposterior radiographs of the clavicles with 45° cranial and caudal inclination, as well as reporting complications. Results: In total, 15 patients were evaluated. The median of surgical time was 50 minutes (IQR 35). The UCLA scale had a median of 35 (IQR 2) at 12 months. All patients presented fracture healing. Minor complications occurred in three cases (20%), with two (13.3%) evolving with plate prominence and one (6.7%) with local paresthesia, while major complications occurred in only one case (6.7%), with suture dehiscence requiring surgical re-approach. Conclusion: MIPO with locking is a viable option for the treatment of displaced fractures of the middle third of the clavicle, with excellent results according to the UCLA scale, fracture healing in all cases, and a low rate of complications. Level of Evidence IV, Case Series.
RESUMO Objetivo: Avaliar os resultados clínicos e radiográficos do tratamento cirúrgico de fraturas do terço médio da clavícula pela técnica de osteossíntese minimamente invasiva com placa (OMIP) bloqueada. Métodos: Série de casos prospectiva que avaliou fraturas desviadas do terço médio da clavícula submetidas à OMIP bloqueada, com procedimentos realizados por um único cirurgião. Os pacientes foram avaliados aos 12 meses por meio da escala da Universidade da Califórnia em Los Angeles (UCLA) e por radiografias das clavículas em anteroposterior (AP) com inclinação cranial e caudal de 45°, além de relatos de complicações. Resultados: Foram avaliados 15 pacientes. A mediana do tempo cirúrgico foi de 50 minutos (IIQ 35). A escala da UCLA aos 12 meses teve mediana de 35 (IIQ 2). Todos os pacientes apresentaram consolidação da fratura. Complicações menores ocorreram em três casos (20%): dois (13,3%) com proeminência da placa e um (6,7%) com parestesia local. Maiores complicações ocorreram em apenas um caso (6,7%), com deiscência de sutura, necessitando de reabordagem cirúrgica. Conclusão: A OMIP bloqueada se mostrou uma opção viável ao tratamento das fraturas desviadas do terço médio da clavícula, com resultados excelentes de acordo com a escala UCLA, consolidação em todos os casos e baixo índice de complicações. Nível de Evidência IV, Série de Casos.

ABSTRACT Objectives: We aimed to compare the functional and radiographical outcomes of reconstruction of acute unstable acromioclavicular joint (ACJ) dislocation using Hook Plate (HP) versus Suture Endobutton (SE) fixation techniques. Methods: Forty-six consecutive patients with grade III to V ACJ dislocation according to Rockwood classification who underwent either HP or SE fixation in the period between January 2017 and June 2020 were evaluated. The treatment modalities were divided into either HP or SE fixation. The radiological assessment included standard anterior-posterior (AP) views to evaluate coracoclavicular (CC) distances for vertical reduction. Results: CC distances were grouped as preoperative (CC1), early postoperative (CC2), and late postoperative (CC3). The distance variance between CC2 and CC3 was referred as ΔCC (CC3 - CC2). A statistically significant difference was found in ΔCC between the two groups (p=0.008). ΔCC was significantly higher in the SE group compared to the HP group (p<0.05). The Constant and UCLA Scores of patients in the SE group were found to be significantly higher than in the HP group patients. Conclusion: Clinical outcomes were more satisfactory in patients with acute unstable ACJ dislocation who underwent SE compared to HP procedures, at the end of the first year. Evidence Level IV; Case Series.
RESUMO Objetivo: Nosso objetivo foi comparar os resultados funcionais e radiográficos da reconstrução da luxação instável aguda da articulação acromioclavicular (ACJ) utilizando técnicas de fixação com placa com gancho (HP) versus botão de sutura (SE). Métodos: 46 pacientes com luxação da ACJ de grau III a V, de acordo com a classificação de Rockwood, que foram submetidos à fixação com HP ou SE no período de janeiro de 2017 a junho de 2020, foram avaliados. As modalidades de tratamento foram divididas em fixação HP ou SE. Na avaliação radiológica, foi utilizada a incidência antero-posterior (AP) para avaliação da redução vertical, por meio da medida da distância córaco-clavicular (CC). Resultados: As distâncias CC foram agrupadas em pré-operatória (CC1), pós-operatória imediata (CC2) e pós-operatória tardia (CC3). A variação da distância entre (CC2) e (CC3) foi denominada ΔCC. Uma diferença estatisticamente significativa foi encontrada na ΔCC entre os dois grupos (p=0,008). O ΔCC foi significativamente maior no grupo SE em comparação com o grupo HP (p <0.05). As pontuações de Constant e UCLA dos pacientes do grupo SE foram significativamente mais elevadas do que as dos pacientes do grupo HP. Conclusão: Os resultados clínicos foram mais satisfatórios com a técnica SE em comparação com a HP ao final do primeiro ano. Nível de Evidência IV; Série de casos.
摘要
It was believed that “all clavicle fractures heal well” is no longer valid. Recent trend is towards operative management, consists of Pre-contoured plate or Titanium Elas?c Nail System(TENS) applica?on. Plate fixa?on remains the mainstay of treatment but Titanium Elas?c Nail System applica?on has gained a?en?on in recent years. This study highlights the comparison between two most common modali?es available for treatment of mid-sha? clavicle fractures. Objec?ves:Compare the func?onal outcome using Neer’s scoring system, radiological outcome and secondary outcomes between two treatment groups. Methods:Pa?ents sa?sfying inclusion criteria were included in our study and randomized into Group A-operated with plate fixa?on and Group B-operated with TENS. Rou?ne postopera?ve protocol and physiotherapy followed. Regular follow up carried out and assessed as per protocol. Results: We had 15 pa?ents in each group by end of our study. There was no significant difference between the two groups in terms of demographics, ?me to surgery, fracture types. Dura?on of hospital stay, mean fracture union ?me were significantly shorter and cosme?cally more sa?sfied in TENS group. Opera?ve ?me, length of incision, periopera?ve blood loss was significantly higher in plate group and length of clavicle be?er restored. Func?onal outcome was excellent with no significant difference between two groups. Conclusion:Both methods return the pa?ents to their pre-injury func?onal levels without significant complica?ons with excellent func?onal outcome. Titanium Elas?c Nail System applica?on has a shorter opera?ve ?me, lesser dura?on of hospital stay, lower infec?on rate and be?er cosme?c outcome sugges?ng this is the preferred method with no comminu?on whereas plate fixa?on is superior in comminuted fractures.

SUMMARY: As natural disasters or crimes, precise postmortem identification is needed especially in case of unknown human remains. The aim of the study is to assess sexual dimorphism by formulating new multivariate equations based on scapular and clavicular parameters for a modern Thai population. Eight left scapular and six left clavicular parameters were measured from 278 individuals (124 males and 124 females for training group; and 15 males and 15 females for test group) of a modern Thai population with age ranges from 19 to 101 years. All scapular and clavicular parameters were sexually dimorphic. Direct and stepwise multivariate discriminant function analysis was performed to generate models. Three direct multivariate discriminant functions showed accuracy rates from 91.1c to 92.3 % (cross-validated range from 90.3 % to 91.5 %). Similarly, three stepwise multivariate discriminant functions showed accuracy rates from 90.7 % to 92.7 % (cross-validated range from 90.7 % to 92.7 %). Moreover, the test group showed 86.67 % to 100 % of sex determination accuracy in six discriminant functions. As recommendation for sex determination by using combination of the scapular and clavicular parameters yields statistically high accuracy for sex determination. Therefore, the accuracies of these multivariate discriminant function equations obtained from scapula and clavicle can be applied for forensic sex determination, especially in modern Thais.
RESUMEN: En casos de desastres naturales o crímenes se requiere una identificación post mortem precisa, especialmente en el caso de restos humanos desconocidos. El objetivo de este estudio fue evaluar el dimorfismo sexual mediante nuevas ecuaciones multivariadas basadas en parámetros escapulares y claviculares para una población tailandesa moderna. Se midieron ocho parámetros escapulares izquierdos y seis claviculares izquierdos de 278 individuos (124 hombres y 124 mujeres para el grupo de entrenamiento; y 15 hombres y 15 mujeres para el grupo de prueba) de una población tailandesa moderna con rangos de edad de 19 a 101 años. Todos los parámetros escapulares y claviculares presentaban dimorfismo sexual. Se realizaron análisis de funciones discriminantes multivariadas directas paso a paso para generar modelos. Tres funciones discriminantes multivariadas directas mostraron tasas de precisión de 91,1 % a 92,3 % (rango de validación cruzada de 90,3 % a 91,5 %). De manera similar, tres funciones discriminantes multivariadas mostraron tasas de precisión de 90,7 % a 92,7 % (rango de validación cruzada de 90,7 % a 92,7 %). Además, el grupo de prueba mostró del 86,67 % al 100 % de precisión en la determinación del sexo en seis funciones discriminantes. Como recomendación para la determinación del sexo mediante el uso de la combinación de los parámetros escapulares y claviculares, se obtiene una precisión estadísticamente alta para la determinación del sexo. Por lo tanto, las precisiones de estas ecuaciones de funciones discriminantes multivariadas obtenidas de la escápula y la clavícula se pueden aplicar para la determinación forense del sexo, especialmente en los tailandeses modernos.

Abstract Objective To analyze the radiological, clinical, and functional outcomes of clavicle fractures treated with the minimally-invasive plate osteosynthesis (MIPO) technique. Methods From June 2018 to July 2019, 17 cases of clavicular fractures were managed using the MIPO technique under C-arm fluoroscopy. The functional outcomes were assessed using the Constant-Murley score and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. The clinical results of union, the complications, the operative time, the hospital stay, as well as infection, were analyzed. Results The mean follow-up time was of 10.41 1.75 months (range: 8 to 14 months). There were 11 male and 6 female patients, with a mean age of 39.05 10.76 years (range: 22 to 57 years). All fractures united on the mean time of 15.35 3.08 weeks (range: 12 to 20 weeks). The mean operative time was of 98.11 13.83 minutes (range: 70 to 130 minutes), and the mean length of the hospital stay was of 4.7 1.12 days (range: 3 to 7 days). The mean Constant-Murley score was of 74.82 6.36 in 4th postoperstive month, and of 92.35 5.48 in the 8th postoperative month, which was statistically significant. The mean DASH score was of 9.94 1.55 in the 4th postoperative month, and of 5.29 1.85 in the 8th postoperative month, which was also statistically significant. One patient had superficial skin infection at the site of the incision. Conclusions The MIPO technique is an alternative method for the fixation of clavicle fractures, but it is technically more demanding, and requires well-equipped operating room facilities.
Resumo Objetivo Analisar o resultado radiológico, clínico e funcional das fraturas da clavícula, tratadas pela técnica de osteossíntese com placa minimamente invasiva (MIPO). Métodos De junho de 2018 a julho de 2019, um total de 17 casos de fraturas claviculares foram tratadas com a técnica de osteossíntese com placa minimamente invasiva (MIPO), sob fluoroscopia com o braço em C. Os resultados funcionais foram avaliados por meio do escore de Constant-Murley e pelo escore de incapacidade do braço, ombro e mão (DASH). Foram analisados os resultados clínicos de consolidação, complicações, tempo cirúrgico, permanência hospitalar e infecção. Resultados O tempo médio de acompanhamento neste estudo foi de 10,41 1,75 meses (variação, 8 a 14 meses). Havia 11 pacientes do sexo masculino e seis do feminino, com média de idade de 39,05 10,76 anos (variação de 22 a 57 anos). Todas as fraturas se consolidaram no tempo médio de 15,35 3,08 semanas (variação, 12 a 20 semanas). O tempo cirúrgico médio foi de 98,11 13,83 minutos (variação, 70 a 130), sendo a permanência hospitalar média de 4,7 1,12 dias (variação de 3 a 7). O escore de Constant-Murley médio foi de 74,82 6,36 no 4° mês e 92,35 5,48 no 8° mês do pós-operatório, o que foi estatisticamente significativo. O escore DASH médio foi de 9,94 1,55 no 4° mês e 5,29 1,85 na 8ª semana do pós-operatório, também sendo estatisticamente significativo. Um paciente apresentou infecção cutânea superficial no local da incisão. Conclusões A técnica MIPO é um método alternativo para a fixação de fraturas da clavícula, porém é tecnicamente mais desafiador, já que necessita de instalações cirúrgicas mais bem equipadas.
