Abstract Objective Research and identification of Cutibacterium acnes (C. acnes) and other microorganisms in deeptissue samples collected in clean shoulder surgeries of patients who did not undergo any previous invasive joint procedure and who had no clinical history of infection. Methods We analyzed the results of cultures of intraoperative deep tissue samples from 84 patients submitted to primary clean shoulder surgery. Tubes containing culture medium were used for storage and transport of anaerobic agents, prolonged incubation time, and mass spectrometer for diagnosis of bacterial agents. Results Bacteria growth was evidenced in 34 patients (40.4%) of the 84 included in the study. Of these, 23 had growth of C. acnes in at least one sample of deep tissue collected, corresponding to 27.3% of the total patients. The second most common agent was Staphylococcus epidermidis, present in 7.2% of the total individuals included. We showed a higher relationship between sample positivity and males, a lower mean age, absence of diabetes mellitus, ASA I score, and antibiotic prophylaxis in anesthetic induction with cefuroxime. Conclusions A high percentage of isolates of different bacteria was found in shoulder tissue samples of patients undergoing clean and primary surgeries, who had no history of previous infection. Identification of C. acnes was high (27.6%), and Staphylococcus epidermidis was the second most frequent agent (7.2%).

Reverse Shoulder Arthroplasty: Evaluation of the Clinical and Functional Outcomes per Etiology / Artroplastia reversa de ombro: Avaliação dos resultados clínicos e funcionais de acordo com a etiologia

Abstract Objective The present study aimed to evaluate the clinical outcomes of reverse shoulder arthroplasty to treat several conditions. Methods Retrospective, longitudinal study analyzing the Constant and University of California at Los Angeles (UCLA) scores and range of motion of patients undergoing reverse shoulder arthroplasty. Results In total, 28 patients were analyzed, with a mean age of 75.6 years old. The mean duration of follow-up was 45 months. Overall, there was a significant variation (p< 0.0001) between the preoperative (10.2 points) and the postoperative UCLA scores (29.6 points), corresponding to a relative increase of approximately 200%. In addition, the mean Constant score was 67.8, and the complication rate was 17.8%. As for functional outcomes per etiology, fracture sequelae cases presented the best mean elevation (165°), Constant score (79 points), postoperative UCLA score (32.5 points), and absolute delta UCLA score increase (22 points), but with no statistical significance. However, cases operated for fracture sequelae showed significantly higher elevation (p= 0.027) and Constant score (p= 0.047) compared to rotator cuff arthropathy cases. In addition, the lowest mean postoperative Constant and UCLA scores were observed for the following etiologies: primary arthrosis, acute fracture, and arthroplasty revision. Conclusion Reverse shoulder arthroplasty showed satisfactory functional outcomes and may be a treatment option not only for rotator cuff arthropathy but for several other conditions.

Resumo Objetivo Avaliar os resultados clínicos da artroplastia reversa do ombro no tratamento de suas diversas indicações. Métodos Estudo longitudinal retrospectivo que analisou os resultados dos escores Constant, UCLA e amplitudes de movimentos dos pacientes submetidos à artroplastia reversa do ombro. Resultados Foram analisados 28 pacientes, a média de idade foi de 75.6 anos, com seguimento médio de 45 meses. No geral, obtivemos uma variação significativa (p< 0,0001) entre o escore UCLA pré-operatório (10,2 pontos) e o escore UCLA pós-operatório (29,6 pontos), o que corresponde a um aumento relativo de aproximadamente 200%. Além disso, obtivemos pontuação média do escore Constant de 67,8 e uma taxa de complicações de 17,8%. Quanto aos resultados funcionais segundo as indicações, os casos de sequela de fratura apresentaram as melhores médias de elevação (165°), escore Constant (79 pontos), escore UCLA pós-operatório (32,5 pontos) e aumento absoluto na variação do escore UCLA (22 pontos), sem significância estatística. Porém, identificou-se que os casos operados por sequela de fratura apresentaram elevação (p= 0,027) e pontuação no escore Constant (p= 0,047) significativamente maiores em relação aos casos de artropatia do manguito rotador. Além disso, observamos que as menores médias dos escores Constant e UCLA pós-operatórios foram obtidos nas seguintes etiologias: artrose primária, fratura aguda e revisão de artroplastia. Conclusão A artroplastia reversa de ombro apresentou resultados funcionais satisfatórios, podendo ser uma opção de tratamento não somente nos casos de artropatia do manguito rotador, mas também em várias outras patologias.

Level V Clearance in Neck Dissection for Papillary Thyroid Carcinoma: A Need for Homogeneous Studies

Abstract Introduction Papillary thyroid carcinoma has a very high rate of lateral neck node metastases, and there is almost unanimity concerning the fact that some sort of formal neck dissection must be performed to address the clinical neck disease in these cases. Although there is an agreement that levels II to IV need to be cleared in these patients, the clearance of level V is debatable. Objectives We herein have tried to analyze various papers that have documented a structured approach to neck dissection in these patients. Moreover, we have also tried to consider this issue through various aspects, like spinal accessory nerve injury and the impact of neck recurrence on survival. Data Synthesis The PubMed, Medline, Google Scholar, Surveillance, Epidemiology, and End Results (SEER), and Ovid databases were searched for studies written in English that focused on lateral neck dissection (levels II-IV or II-V) for papillary thyroid carcinoma. Case reports with 10 patients or less were excluded. Conclusions The current evidence is equivocal whether to clear level V or not, and the studies published on this issue are very heterogeneous. Level II-IV versus level II-V selective neck dissections in node-positive papillary thyroid carcinoma patients is far from categorical, with pros and cons for both approaches. Hence, we feel that there is a need for more robust homogeneous data in order to provide an answer to this question.

Subluxation of the shoulder is the most common musculoskeletal complication of Central and Peripheral Nervous System disorders, which leads to decreased movement, function, and increased pain. Objective: Orthosis is one of the assistive devices used in the treatment of this pathology and it focuses in correcting deformity, decreasing pain and providing function to the affected member. This study proposes a new methodology for designing and manufacturing customized shoulder stabilization orthoses with 3D scan image acquisition and 3D printing technologies, for ensuring better adaptability and comfort for the user. Method: The methodology used in this study was divided into five phases: case study, scanning, modeling and 3D printing; and finishing. The case study included a user with brachial plexus injury that motivated the original design of hybrid orthosis, personalized and manufactured in 3D, with rigid structure and traction straps, for stabilizing the shoulder, reduce pain and allowing function. Results: After 3D scanning, we used specialized software to process the three-dimensional STL image. Optimization of the project with generation of models and prototyped parts in FDM based on the user evaluations was performed. The developed concept was: personalized orthosis, easy to clean and wear, resistant, articulated, for wearing in both arms with traction straps in rigid fabric coupled to the waist. Conclusion: The user test corroborated with the designed concept and showed a preliminary prototype with good trunk coupling, satisfactory traction and possibility of performing a greater number of ADLs with less pain and/or tiredness

Posture and mobility of the upper body quadrant and pulmonary function in COPD: an exploratory study

ABSTRACT Background There is limited evidence regarding interactions between pulmonary (dys)function, posture, and mobility of the upper body quadrant in patients with chronic obstructive pulmonary disease (COPD). Objectives This exploratory study aimed to investigate whether postural alignment and mobility of the upper quadrant are related to changes in pulmonary function and compare such variables between patients with COPD and healthy individuals. Method Fifteen patients with COPD (67.93±9.71yrs) and 15 healthy controls (66.80±7.47yrs) participated. Pulmonary function (FEV1, FVC) was assessed with spirometry. Alignment and mobility of the head, thoracic spine, and shoulder were assessed using digital photographs. Pectoralis minor muscle (PmM) length and thoracic excursion were assessed with a measuring tape. Groups were compared and linear regression analyses were used to assess potential relationships between postural and mobility variables and pulmonary function. Results Patients with COPD were more likely to have a forward head position at maximal protraction (28.81±7.30º vs. 35.91±8.56º, p=0.02) and overall mobility of the head (21.81±10.42º vs. 13.40±7.84º, p=0.02) and a smaller range of shoulder flexion (136.71±11.91º vs. 149.08±11.58º, p=0.01) than controls. Patients’ non-dominant PmM length and maximal head protraction were predictors of FEV1 (r2adjusted=0.34). These variables, together with the upper thoracic spine at maximal flexion and thoracic kyphosis at maximal extension, were predictors of FVC (r2adjusted=0.68). Conclusion Our findings suggest that impaired pulmonary function is associated with muscle length and mobility adaptations. Further studies are needed to understand the underlying mechanisms and clinical value of these relationships.

Há uma zona de conforto ideal para escrever na lousa que previna a dor em ombro de professores? / Is there an ideal comfort zone for writing in blackboard to preventshoulder pain in teachers?

As doenças do ombro estão fortemente relacionadas aos afastamentos de trabalho e os professores estão incluídos entre os profissionais que apresentam sobrecarga nesta articulação pelas posturas de trabalho. Os objetivos deste estudo foram identificar prevalências de queixas musculoesqueléticas dentre estes profissionais e estabelecer uma zona de conforto para escrita na lousa. A avaliação das queixas foi realizada através do Questionário Nórdico de Sintomas Osteomusculares e Mapa de Desconforto Postural em 82 professores do Ensino Básico, Fundamental e Médio. A zona de conforto foi avaliada através de estudo psicofísico utilizando as Escalas Visual Analógica e de Borg. Os resultados mostraram que coluna lombar, pernas e ombro direito apresentaram maiores índices de queixas de dor musculoesquelética e que alturas na faixa de 20 cm acima da altura do ombro a 20 cm abaixo não tiveram relação causa-efeito com o nível de desconforto para escrever na lousa (p<.05). Concluiu-se que professores podem apresentar sobrecarga postural no ombro dependendo da altura em que escrevem na lousa.

Shoulder disorders represent are highly related with occupational diseases and teachers are included amongprofessionals who have this joint overloaded by working postures. The objectives of this study were to identify the prevalence of musculoskeletal complaints among these professionals and to establish a comfort zone for writing on a blackboard. The evaluation of complaints was performed using the Nordic Musculoskeletal Questionnaire and Map of Postural Discomfort (or Postural Discomfort Map) in 82 Elementary and High School teachers. The comfort zone was evaluated by psychophysical study using the Visual Analogue and Borg Scales. The results showed that lumbar spine, legs and right shoulder had higher rates of complaints and heights between 20 cm above and 20 cm below shoulderlevel showed no discomfort to blackboard writing (p.<05). It wasconcluded that teachers may have postural overload on shoulderdepending on the height that they write on the blackboard.

Strength deficits of the shoulder complex during isokinetic testing in people with chronic stroke

OBJECTIVES: To examine the strength deficits of the shoulder complex after stroke and to characterize the pattern of weakness according to type of movement and type of isokinetic parameter. METHOD: Twelve chronic stroke survivors and 12 age-matched healthy controls had their shoulder strength measured using a Biodex isokinetic dynamometer. Concentric measures of peak torque and work during shoulder movements were obtained in random order at speeds of 60°/s for both groups and sides. Type of movement was defined as scapulothoracic (protraction and retraction), glenohumeral (shoulder internal and external rotation) or combined (shoulder flexion and extension). Type of isokinetic parameter was defined as maximum (peak torque) or sustained (work). Strength deficits were calculated using the control group as reference. RESULTS: The average strength deficit for the paretic upper limb was 52% for peak torque and 56% for work. Decreases observed in the non-paretic shoulder were 21% and 22%, respectively. Strength deficit of the scapulothoracic muscles was similar to the glenohumeral muscles, with a mean difference of 6% (95% CI -5 to 17). Ability to sustain torque throughout a given range of motion was decreased as much as the peak torque, with a mean difference of 4% (95% CI -2 to 10). CONCLUSIONS: The findings suggest that people after stroke might benefit from strengthening exercises directed at the paretic scapulothoracic muscles in addition to exercises of arm elevation. Clinicians should also prescribe different exercises to improve the ability to generate force and the ability to sustain the torque during a specific range of motion. .

Objetivos: Avaliar o posicionamento estático da escápula no gradil costal em indivíduos saudáveis, por meio da avaliação clínica e radiográfica, avaliar a confiabilidade interavaliador do exame clínico e verificar a confiabilidade do método de avaliação em comparação ao exame radiográfico. Métodos: foram selecionados 30 indivíduos adultos de ambos os sexos sem diagnóstico de doenças nos ombros. O exame clínico estático, seguindo o protocolo sugerido por Burkhart e cols., foi realizado repetidamente por 2 examinadores independentes; a seguir, foi realizado o exame radiográfico, que posteriormente foi examinado pelo primeiro avaliador. Resultados: 73,3% dos indivíduos apresentaram o posicionamento da escápula considerado dentro da normalidade. A confiabilidade interavaliador e a confiabilidade do exame clínico em relação à radiografia foram considerados baixa e muito baixa respectivamente. Conclusão: a reprodutibilidade da avaliação realizada por Burkhart foi considerada de satisfatória a boa, enquanto que a reprodutibilidade inter-avaliador do exame clínico estático e a reprodutibilidade do exame clínico com a radiografia foram consideradas de pobres a satisfatórias. Nível de Evidência III, Estudo de Pacientes não Consecutivos.

Objective: Evaluate the static positioning of the scapula on the rib cage in healthy subjects by means of clinical and radiographic evaluation to assess interexaminer reliability of clinical examination and verify the reliability of this evaluation method compared to the radiographic examination. Methods: we selected 30 adult individuals of both sexes with no diagnosis of shoulder pathology. The static clinical examination, following the protocol suggested by Burkhart et al, was performed repeatedly by two independent examiners, followed by the radiographic examination, which was later examined by the first evaluator. Results: 73.3% of the subjects showed positioning of the scapula considered normal. The interexaminer reliability and that of the clinical examination in relation to radiography were considered low and very low, respectively. Conclusion: The reproducibility of the evaluation performed by Burkhart was considered satisfactory to good, while the interexaminer reproducibility of the clinical examination and the static reproducibility of the clinical examination with radiography were considered poor to satisfactory. Level of Evidence III, Study of Nonconsecutive Patientes.

Posterior shoulder tightness and rotator cuff strength assessments in painful shoulders of amateur tennis players

BACKGROUND: Previous studies have shown a relationship between shoulder posterior capsule tightness and shoulder pain in overhead athletes. However, this relationship has not been studied in tennis players. OBJECTIVES: Assessment of the shoulder range of motion (ROM), strength and posterior capsule tightness of skilled amateur tennis players who had complaints of dominant shoulder pain in comparison with tennis players without pain. METHOD: Forty-nine skilled amateur tennis players were distributed in 2 groups: Control Group (n=22) and Painful Group (n=27). The first group was composed of asymptomatic subjects, and the second was composed of subjects with shoulder pain on the dominant side. These groups were evaluated to determine the dominant and non-dominant shoulder ROM (internal and external rotation), isometric shoulder strength (internal and external rotation) and posterior shoulder tightness by blind evaluators. RESULTS: The ANOVA results indicated significant differences between the groups in the dominant shoulder ROM, posterior capsule tightness, external rotation strength and strength ratio (p<0.05). The intragroup analysis (dominant versus non-dominant) in the Painful Group displayed a significant difference for ROM, posterior capsule tightness and external rotation strength (p<0.05). CONCLUSIONS: The tennis players with pain in the dominant shoulder presented greater posterior capsule tightness, internal rotation deficit (ROM), external rotation gain (ROM) and deficits in external rotation strength than the tennis players without pain. .

Anatomical and clinical study of the subscapular nerves

Introduction: Painful shoulder on hemiplegic patients has been associated to subscapular muscle spasticity.An alternative for treatment is based on subscapular nerve block using phenol. However, there is lack ofinformation on anatomical references for subscapular nerves blockage technique. The aim of this study wasto determine mean values and confidence intervals for maximum penetration points in order to facilitateblockage during anesthetic procedure of subscapular nerves. Material and methods: Using 30 dissected adultcadaver limbs, the medial edge of scapula and a horizontal plan to the lower edge of the bone spine wereidentified. The maximal and minimal angles of the penetration points of the subscapular nerve both above andbelow the horizontal plan were measured, as well as the minimal and maximal distances from the medial edgeof scapula. Superior and inferior bisector angles and the mean horizontal distance (in mm) were calculatedfor descriptive analysis. Kolmogorov-Smirnov normality test indicated the normal distribution of the data(p > 0.05). Results: Mean superior angle was 6.63° (confidence interval 4.52-8.75), mean inferior angle was11.30° (confidence interval 8.73-13.86) and mean horizontal distance was 72.53 mm (confidence interval69.25-75.80). Conclusions: According to this data, for maximum points blocking after solution injection, theneedle should be introduced horizontally at the scapula spine level under its medial edge to a mean depth of72.53 mm. Then, the needle must be driven upwards in a 6.63° angle and later, driven downwards to form a11.30° angle with the horizontal plan. Those mean values represent 95% of the distribution.

Functional outcomes of conservatively treated clavicle fractures

OBJECTIVE: The main aim of the study was to analyze the outcomes of clavicle fractures in adults treated non-surgically and to evaluate the clinical effects of displacement, fracture patterns, fracture location, fracture comminution, shortening and fracture union on shoulder function. METHODS: Seventy clavicle fractures were non-surgically treated in the Orthopedics Department at the Tuanku Ja'afar General Hospital, a tertiary care hospital in Seremban, Malaysia, an average of six months after injury. The clavicle fractures were treated conservatively with an arm sling and a figure-eight splint for three weeks. No attempt was made to reduce displaced fractures, and the patients were allowed immediate free-shoulder mobilization, as tolerated. They were prospectively evaluated clinically and radiographically. Shoulder function was evaluated using the Constant scoring technique. RESULTS: There were statistically significant functional outcome impairments in non-surgically treated clavicle fractures that correlated with the fracture type (comminution), the fracture displacement (21 mm or more), shortening (15 mm or more) and the fracture union (malunion). CONCLUSION: This article reveals the need for surgical intervention to treat clavicle fractures and improve shoulder functional outcomes.

Comparison of quality of life, satisfaction with surgery and shoulder-arm morbidity in breast cancer survivors submitted to breast-conserving therapy or mastectomy followed by immediate breast reconstruction

OBJECTIVES: This study was designed to compare the prevalence of shoulder-arm morbidity, patient satisfaction with surgery and the quality of life of women submitted to breast-conserving therapy or modified radical mastectomy and immediate breast reconstruction . METHODS: This study was a cross-sectional study of women who underwent breast-conserving therapy (n=44) or modified radical mastectomy and immediate breast reconstruction (n=26). Quality of life was evaluated with the SF-36 Health Survey Questionnaire. RESULTS: No differences were found in the prevalence of lymphedema. The movements that were most commonly affected by these procedures were abduction, flexion and external rotation. When the two groups were compared, however, we only found a statistically significant difference for the prevalence of restricted internal rotation, which occurred in 32 percent of women in the breast-conserving therapy group and 12 percent of those in the modified radical mastectomy and immediate breast reconstruction group (OR: 7.23; p=0.03 following adjustment for potential confounding factors). No difference in quality of life or satisfaction with surgery was found between the two groups. CONCLUSIONS: These data suggest that the type of surgery did not affect the occurrence of lymphedema. Breast-conserving therapy, however, increased the risk of shoulder movement limitation. No differences were found between the two surgical techniques with respect to quality of life or satisfaction with surgery.

Resultados do tratamento artroscópico das rupturas do manguito rotador / Outcomes of arthroscopic treatment for rotator cuff tears

OBJETIVO: Analisar os resultados do reparo artroscópico das rupturas do manguito rotador. MÉTODOS: Realizado estudo retrospectivo com avaliação dos resultados da técnica em 42 pacientes operados entre 2002 e 2006. O seguimento médio foi de 31 meses e a média de idade foi de 57 anos, sendo o lado dominante operado em 73,8 por cento dos casos. Para avaliação foram usadas escalas de UCLA e Escala Visual Analógica da dor no pós-operatório. RESULTADOS: Os resultados foram satisfatórios em 85,7 por cento (59,5 por cento excelentes e 26,2 por cento bons respectivamente) e insatisfatórios em 14,3 por cento dos pacientes. Nos casos com lesões associadas, a mais frequente foi no tendão da porção longa do bíceps (57,1 por cento). Associação com outras lesões não comprometeu o resultado. O mesmo aconteceu com relação a idade e tempo de acompanhamento pós-cirurgia. Quanto ao tamanho da lesão, diferença significativa ocorreu nos casos de lesões grandes e maciças demonstrando resultados inferiores em relação às pequenas e médias. A função foi inferior principalmente nos casos de lesão maciça. CONCLUSÃO: A reparação artroscópica das lesões do manguito rotador (MR) proporciona baixa morbidade cirúrgica e possibilita diagnóstico de lesões articulares associadas. O benefício do procedimento foi confirmado principalmente pela melhora significativa da dor, mesmo nos casos de lesões maiores.

OBJECTIVE: To evaluate the results of arthroscopic treatment for rotator cuff tears. METHODS: A retrospective study was carried out demonstrating the results of this technique in 42 patients operated between 2002 and 2006. The mean follow-up was 31 months and average age was 57 years. The dominant limb was operated in 73.8 percent of cases. Function and pain were evaluated using criteria of UCLA Score System and Visual Analogic Scale respectively. RESULTS: The results were satisfactory in 85.7 percent (59.5 percent excellent and 26.2 percent good), with 14.3 percent unsatisfactory. The most frequent associated lesion was the long head of the biceps tendon (57.1 percent). Nevertheless, the presence of other lesions did not alter the end results. The same occurred in relation to age and follow-up period. When comparing large and massive tears with small and mid-sized ones, the first group had significantly inferior functional results. The function was worse in cases of massive tear. CONCLUSION: Arthroscopic rotator cuff repair provides lower surgical morbidity and intrarticular diagnosis of associated lesions in comparison to open surgery. The benefit of the procedure was confirmed mainly by pain relief, even in cases of more extensive lesions.

Estudo transversal sobre o tratamento das lesões acrômioclaviculares agudas / Transversal study about acute acromioclavicular lesions

OBJETIVO: O objetivo do presente estudo transversal é verificar como o ortopedista brasileiro interpreta as lesões acromioclaviculares quanto aos critérios para a indicação do tratamento cirúrgico ou não, seus métodos preferidos, as complicações mais frequentes e os resultados obtidos. MÉTODOS: Durante o 6º Congresso Brasileiro de Cirurgia do Ombro e Cotovelo (CBOC) e o 38º Congresso Brasileiro de Ortopedia e Traumatologia (CBOT) foram distribuídos 507 questionários, sendo considerados 478 para análise. RESULTADOS: Em relação ao tratamento das LAC tipo I e II, a maioria dos entrevistados utilizam métodos não cirúrgicos. Em contraposição nas LAC IV, V e VI 475 (99,4 por cento) dos entrevistados tratam essas lesões cirurgicamente. Nas LAC tipo III não existe uma definição na escolha do tratamento cirúrgico ou não cirúrgico para 386 (80,7 por cento) entrevistados, sendo que o fator mais importante para tomada de decisão para a maioria dos entrevistados é a atividade esportiva do paciente e a idade. CONCLUSÃO: Nas LAC tipo III não há consenso, sendo o tratamento determinado conforme as características do paciente, contudo na literatura atual há uma tendência para o tratamento não cirúrgico destas lesões.

The objective of the present transversal study is to check how Brazilian orthopedists treat these injuries, their criteria for choosing the treatment, results and complications. METHODS: During the 6th Brazilian Congress of Shoulder and Elbow Surgery (CBOC) and the 38th Brazilian Congress of Orthopaedics and Traumatology (CBOT) 507 questionnaires were distributed (148 CBOC and 359 CBOT), with 478 being considered for analysis. RESULTS: Regarding type-I and -II ACIs, most of the respondents use traditional non-surgical methods. On the other hand, for type-IV, V and VI injuries, 475 (99.4 percent) of the respondents indicate surgical methods. Concerning type-III injuries, there is no consensus in the selection between traditional and surgical treatment for 386 (80.7 percent) respondents, with the most important factor for selecting a given treatment method being the patient's level of sports practice and age. CONCLUSION: There is no consensus regarding type-III ACIs, and the selection of the best treatment method is made according to patient's individual characteristics. However, current literature shows a trend towards non-operative methods.

Effects of Supervised Exercise Therapy in Patients Receiving Radiotherapy for Breast Cancer

PURPOSE: Postoperative radiotherapy for breast cancer has a number of associated complications. This study examined whether supervised moderate-intensity exercise could mitigate the complications that occur during radiotherapy. PATIENTS AND METHODS: Forty women were randomized before radiotherapy after various operations for breast cancer. Seventeen patients who were assigned to the exercise group performed supervised moderate-intensity exercise therapy for 50 min 3 times per week for 5 weeks. Twenty-three patients in the control group were asked to perform self-shoulder stretching exercise. The World Health Organization Quality of Life-BREF (WHOQOL-BREF), brief fatigue inventory (BFI), range of motion (ROM) of the shoulder, and pain score were assessed before and after radiotherapy. RESULTS: There were no significant differences noted at baseline between groups. In the exercise group, there was an increase in the WHOQOL-BREF and shoulder ROM and decrease in BFI and pain score after radiotherapy. On the other hand, patients in the control group showed decrease in the WHOQOL-BREF and shoulder ROM and increase in BFI and pain score after radiotherapy. There were statistically significant differences in the changes in the WHOQOL, BFI, shoulder ROM, and pain score between the groups. CONCLUSION: Patients receiving radiotherapy for breast cancer may benefit in physical and psychological aspects from supervised moderate-intensity exercise therapy.

Constant shoulder score following scapulectomy

The indications and techniques of scapulectomy have been well described in the literature but little has been reported on the objective functional outcome. We present a series of 4 patients who had total or subtotal scapulectomy for neoplasms of the scapula. The shoulder function was evaluated using the Constant Functional Scoring system. Three of 4 patients scored excellent with no impairment of daily living activities. Preservation of the glenoid was associated with best results. The use of Constant shoulder score is a valuable tool in assessing the functional outcome following scapulectomy

Ultrasonido del hombro doloroso / Ultrasound of the pain shoulder

La ecografía o ultrasonido de alta resolución es un método de muy alto rendimiento en el diagnóstico de una variedad de patologías que causan dolor de hombro, especialmente la relacionada con el mango rotador. En manos experimentadas presenta altísimo rendimiento y permite diagnosticar en etapas más precoces, lo cual redunda en una instauración más temprana de la terapia
