RANGE OF MOTION AFTER BONE BLOCK PROCEDURES FOR SHOULDER INSTABILITY: SYSTEMATIC REVIEW.

Objective: to determine the surgical indications for glenoid bone grafting associated with better postoperative ranges of motion. Methods: This systematic review was conducted according to PRISMA. The included studies were subdivided according to the criteria used to indicate glenoid bone graft surgery: group for radiological indications only (Group R), group for radiological indications associated with clinical indications (Group R + C), and group for arthroscopic indications (Group A). The extracted and evaluated data were the range of motion of the shoulder. Results: in the electronic search conducted in October 2022, 1567 articles were selected. After applying the inclusion criteria, 14 articles were selected for the systematic review. Regarding the ranges of motion, group A had the highest number of statistically positive results together with group R. Group A showed positive results in elevation parameters, loss of lateral rotation in adduction, and medial rotation in abduction. Group R showed positive results in lateral rotation in adduction and loss of lateral rotation in adduction. On the other hand, Group R + C was the one that presented the highest number of statistically negative results, in the following parameters: elevation, lateral rotation in abduction, loss of lateral rotation in adduction, and medial rotation in abduction. Conclusion: the subgroups presented variable results in the evaluated parameters; however, the groups with arthroscopic and radiological indications showed the highest number of positive results, with the latter group showing the best results regarding lateral rotation.

Shoulder injuries in Brazilian professional football players: epidemiological analysis of 3828 games.

OBJECTIVES: Football is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships. METHODS: Data were collected throughout the championships, and club physicians medically evaluated each player during official games using two online forms. The collected information included the player's age and position, injury diagnosis, laterality, location on the field where the injury occurred, playing time, imaging examinations performed, need for surgical treatment, time to return to play (TRP), and recurrence of the injury. The incidence of injuries was evaluated using the Federation Internationale de Football Association (FIFA) incidence formula. RESULTS: A total of 107 shoulder injuries were recorded (4.3% of all injuries), with a FIFA incidence of 0.847. Glenohumeral dislocations (GHDs) and acromioclavicular dislocations (ACDs) accounted for 37.38% and 35.51% of all shoulder injuries, respectively. Goalkeepers and defenders presented, respectively, a 2.15 and 1.57 times increased risk of suffering shoulder injuries, while attackers presented a 0.63 times decreased risk. Injury recurrence was observed in 14.95% of cases, with GHDs and ACDs showing recurrence rates of 35.00% and 5.26%, respectively. Surgery was performed in 9.35% of cases, with GHDs representing 50% of all surgeries. The average TRP was 22.37 days, with severe and major injuries accounting for 11.21% and 10.28% of all injuries, respectively. Goalkeepers had the highest average TRP of 36.15 days. Recurring injuries had a higher average TRP of 33.44 days compared to nonrecurring injuries, which had an average TRP of 20.43 days. Surgically treated injuries had the highest average TRP of 112.5 days. CONCLUSION: Shoulder injuries in the professional football scenario are of great concern due to the high recurrence rate and need for surgical treatment, which will lead to a long TRP. These findings emphasize the need to implement prevention protocols and effective treatments to reduce the consequences of such injuries, which are usually underestimated in this sport. LEVEL OF EVIDENCE: III.

Can three-dimensional models enhance understanding and knowledge of rotator cuff tears?

OBJECTIVES: Magnetic resonance imaging (MRI) is currently the standard diagnostic tool for rotator cuff tears. However, its two-dimensional (2D) output, displayed on a monitor, can complicate the interpretation of anatomy. Three-dimensional (3D) imaging may offer a solution to this issue. This study aimed to demonstrate the diagnostic and interpretive value of a 3D model in assessing lesion anatomy. The hypothesis was that 3D models, compared to 2D MRI, can enhance the comprehension and knowledge of rotator cuff injuries, improve the application of classifications for total tears, and provide a more precise definition of the size and type of tear. METHODS: A prospective single-centre study was conducted. 3D models for rotator cuff tears were created and analysed in conjunction with preoperative MRI for each patient up to 2 months before surgery. The 3D models were based on the preoperative MRI. Collected data included 2D plane measurements by MRI in coronal and sagittal planes, descriptions of 3D lesion geometry (new shapes), 3D measurements in coronal and sagittal planes, arthroscopic classifications of rotator cuff injuries, and arthroscopic measurements in coronal and sagittal planes. RESULTS: After examining 25 cases, 3D imaging demonstrated similar arthroscopic values post-bursectomy in the sagittal plane (16.70 â€‹mm for 3D and 18.28 â€‹mm for post-bursectomy, p-value â€‹= â€‹0.189), although these measurements did not align with those of MRI (which underestimated measurements, p-value â€‹= â€‹0.010). Both MRI measurement and 3D imaging showed similar measurement accuracy in the coronal plane when compared to arthroscopic measurements taken before and after bursectomy. The creation of 3D objects enabled the analysis of new geometries, including the length, width, and depth of each lesion. These geometries included the rectangle, rectangular trapezoid, scalene trapezoid, irregular pentagon, and irregular hexagon. CONCLUSIONS: 3D models can enhance the understanding and knowledge of rotator cuff injuries. They can be a promising tool for diagnosing and interpreting the anatomy of the injury, particularly in the sagittal plane. The new 3D understanding of the pathological process has led to the description of new geometric features not visible in conventional 2D MRI. LEVEL OF EVIDENCE: II - Development of diagnostic criteria on consecutive patients (all compared to "gold" standard).

Evaluation of Screws Positioning in Latarjet Surgery: Is There a Correlation between Parallelism to Glenoid and Radiographic Complications?

Objective To evaluate whether the parallelism of screws with glenoid in Latarjet surgery interferes in the positioning of the graft and to verify the reproducibility of a method of measuring screws positioning. Methods Retrospective, multicenter study, of patients with anterior shoulder instability submitted to modified Latarjet surgery and at least one year of postoperative follow-up. Two radiologists analyzed the postoperative tomographic images, acquired in a database, to evaluate the positioning of screws and radiographic complications. Results We evaluated 34 patients, aged between 21 and 60 years, one of them with bilateral shoulder involvement, totaling 35 shoulders evaluated. The tomographic evaluation of the inclination angles of the screws showed no difference between the observers. There was intra- and interobserver agreement to evaluate the following surgical parameters: graft position, presence or not of radiographic complications. Conclusion The technique described for measuring the parallelism of screws in Latarjet surgery presented a very good and excellent intra-observer agreement, respectively. Screw parallelism with glenoid is recommended; however, it is not a mandatory and unique condition to avoid radiographic complications.

Glenoid Bone Loss - A Retrospective Evaluation of Functional Outcomes after Bone Block Surgery for Anterior Shoulder Instability in High-demand Athletes.

Objective This study assesses the relationship between the glenoid bone loss size and range of motion, functional outcomes, and complications in high-performance athletes undergoing bone block surgery for anterior shoulder instability. Methods This retrospective study evaluated postoperative outcomes in athletes submitted to bone block surgery for anterior shoulder instability. In 5 years, 41 shoulders underwent the procedure; 20 had bone losses up to 15%, and 21 shoulders presented bone losses ranging from 15% and 25%. Results There was no statistically significant difference regarding postoperative complications, new dislocations, and the rate of return to sports. In addition, the quantitative criteria evaluated, i.e., ranges of motion and functional scores, showed no statistically significant difference between groups. Conclusion The size of the bone loss per se does not seem to affect functional outcomes and complications from these procedures, which are safe techniques for small and large bone losses.

Objective To provide a current overview of the Bristow-Latarjet surgery in Brazil. Materials and Methods This cross-sectional study was based on an electronic questionnaire with 26 items, which was sent to active members of the Brazilian Society of Shoulder and Elbow Surgery (Sociedade Brasileira de Cirurgia do Ombro e Cotovelo, SBCOC, in Portuguese). The questionnaire addressed training, surgical technique, complications, and postoperative management. Results We sent the questionnaire to 845 specialists from April 20 to May 12, 2021, and 310 of them answered i in full. During their specialization, most specialists participated in up to ten Bristow-Latarjet procedures. The most frequent complication was graft fracture, while the most common technical difficulty was screw positioning. In total, 50.6% and 73.9% reported having experienced intraoperative and postoperative complications respectively; 57.1% declared performing subscapularis suture; 99.7% indicated postoperative immobilization; and 61.9% considered graft consolidation fundamental. Conclusion Most specialists participated in up to ten Bristow-Latarjet procedures during the specialization, but 13.5% of them graduated without participating in the surgery. The most frequent complication was graft fracture. The most common technical difficulty was screw positioning. Most participants prefer postoperative immobilization since they believe graft consolidation is essential to resume the practiced of sports. The highest complication rate occurred with specialists who have obtained their titles 11 to 15 years ago. In Brazil, the Southeast region is the largest producer of specialists and has the highest concentration of these professionals.

Acute Distal Biceps Tendon Injury: Diagnosis and Treatment / Lesões agudas do tendão distal do bíceps: Diagnóstico e tratamento

Abstract Acute distal biceps injuries clinically present with sudden pain and acute loss of flexion and supination strength. The main injury mechanism occurs during the eccentric load of the biceps. The hook test is the most significant examination test, presenting the highest sensibility and specificity for this lesion. Magnetic resonance imaging, the gold standard imaging test, can provide information regarding integrity and identify partial and/or complete tears. The surgical treatment uses an anterior or double approach and several reattachment techniques. Although there is no clinical evidence to recommend one fixation method over the other, biomechanical studies show that the cortical button resists better to failure. Although surgical treatment led to an 89% rate of return to work in 14 weeks, the recovery of high sports performance occurred in 1 year, with unsustainable outcomes.

Resumo As lesões agudas do tendão distal do bíceps se apresentam, clinicamente, com uma dor súbita associada a perda aguda de força de flexão e supinação. Seu principal mecanismo de lesão ocorre durante contração excêntrica do bíceps. O "Hook Test" é o principal teste semiológico, sendo o mais sensível e específico. A ressonância magnética, exame padrão ouro para o diagnóstico, pode fornecer informações sobre a integridade, identificando as lesões parciais e/ou completas. O tratamento cirúrgico pode ser realizado por duas vias principais: anterior e por dupla via porém as técnicas de reinserção tendínea são diversas não havendo evidência clínica que recomende um método de fixação em detrimento ao outro; embora o botão cortical apresente maior resistência a falha nos estudos biomecânicos. Com o tratamento cirúrgico o retorno as atividades laborais foi de 89% em 14 semanas (média) porém ao esporte de alto rendimento o prazo foi longo, média de 1 ano, e não duradouro.

Resultados Não houve diferença estatisticamente significativa com relação a complicações pós-operatórias, novas luxações, e na taxa de retorno ao esporte. Os critérios quantitativos avaliados - arcos de movimento e escores funcionais - também não apresentaram diferença estatisticamente significativa entre os grupos. Conclusão O tamanho do defeito ósseo por si só não parece afetar os resultados funcionais e as complicações desses procedimentos, sendo uma técnica segura tanto para defeitos pequenos, quanto para os maiores.

What is the best position for coracoid fixation in the Latarjet procedure?

Hypothesis: Multiple problems and complications associated with Latarjet fixation have been described; thus, this is the first study in the literature to identify the maximum allowed screw clamping force and best fixation screw position for Latarjet surgery. Methods: A variation of distal and proximal coracoid screw positions with and without a flat washer was evaluated through finite element analysis, at a minimum distance of 3 mm from the edge. A loading progression test was performed until the maximum stress reached a limit imposed by the bone yield. We identified the maximum allowed screw clamping force based on a von Mises and maximum principal stresses failure theory. Results: When using the flat washer, the cortical bone generally has only space for 1 piece. For this reason, as a primary study, it was observed that when the distal screw was more than 7 mm from the edge, the clamping force supported will be higher than that during the proximal fixation regardless of the proximal location screw. We have found that the best position is 7 mm from the distal edge, with the highest compression of 445 N (7 mm proximal distance, 5 mm distal distance) in due respect to the von Mises failure theory. To get around this lack of space situation, in this study, we have proposed a fixation plate to replace the flat washer. This plate has shown very interesting values when compared to the previously flat washer study, but now, for both screw holes. With those results, we can assure that using a fixation plate like this will ensure surgery safety and higher allowed compression force when clamping the bolts. Conclusion: The distal screw provided higher tensile strength values when located more than 7 mm from the coracoid edge. The geometry of the coracoid in its distal position supports higher stress loads than in the proximal position. When the flat washer was in the proximal position, the coracoid was submitted with a more distributed and uniform load, preventing localized bone damage as a crush.

RESULT OF BONE BLOCKING SURGERY IN COMBAT ATHLETES WITH ANTERIOR SHOULDER INSTABILITY: A PROSPECTIVE STUDY.

Objective: This study aims to understand the way fighting athletes respond to bone block surgery in the treatment for shoulder instability. Methods: Prospective clinical study with competitive fighters with shoulder instability who underwent bone block surgery from 2013 to 2016, followed by a postoperative rehabilitation protocol. For the evaluation, eight combat athletes with anterior shoulder instability were treated, with a total of nine shoulders, since one athlete underwent bilateral surgery. All patients signed the Free and Informed Consent Form. The evaluation protocol included medical consultation, radiography of the operated shoulder, degree of active and passive lateral rotation; degree of active and passive elevation; visual analogue scale (VAS) for pain; Athletic Shoulder Outcome Rating Scale (EROE; acronym in Portuguese) scores; Western Ontario Shoulder Instability Index (WOSI), and American Shoulder and Elbow Surgeons (ASES). Results: We observed a decrease in the range of passive and active movement in the recent postoperative period. In later postoperative, values were close to those in the preoperative period at the end of the follow-up. There was improvement in pain, and in all ASES, WOSI and EROE scores no complications were documented. As for returning to sport, two athletes did not return, one of them due to shoulder pain and the other due to retirement. Conclusion: Bone block surgery has shown good functional results in uncomplicated combat athletes. Level of Evidence IV, Prospective Case Series.

Rotator Cuff Lesion and Obesity: A Demographic and Metabolic Evaluation / Lesão do manguito rotador e obesidade: Uma avaliação demográfica e metabólica

Abstract Objective To analyze the relationship between the presence and severity of rotator cuff (RC) injury with obesity and the time of exposure to obesity. Secondarily, to evaluate the relationship and prevalence of demographic and metabolic factors in obese individuals with RC injury. Methods This is a cross-sectional study with 235 obese patients (body mass index [BMI] 30 kg/m2). Demographic data (age and gender), metabolic data (hypertension, diabetes mellitus, lipid profile, and time of exposure to obesity), physical examination (weight, height, waist circumference, and clinical tests), and musculoskeletal ultrasound examination were used to analyze the results. Results There was no evidence of an association between RC injury and BMI (p » 0.82), time of exposure to obesity (p » 0.29), or abdominal circumference (p » 0.52). In the subgroup with injury, age (p < 0.001), presence of diabetes mellitus (p » 0.013), hypertension (p < 0.001), level of high-density lipoprotein (HDL) (p » 0.026), and time of exposure to obesity (p < 0.001) were significantly greater compared to the subgroup without injury. In the search for other parameters independently associated with RC injury, associations were observed with age (p » 0.0003) and hypertension (p » 0.004). Conclusion We did not evidence an association between obesity and the time of exposure to it with the occurrence and severity of RC injury. However, individuals with injury had a longer time of exposure to obesity and prevalence of metabolic disorders than individuals without RC injury. In addition, our findings suggest an association between systemic arterial hypertension (SAH) and advanced age with RC injury.

Resumo Objetivo Analisar a relação da presença e da gravidade da lesão do manguito rotador (MR) com a obesidade e o tempo de exposição à obesidade. De forma secundária, avaliar a relação e a prevalência de fatores demográficos e metabólicos em indivíduos obesos com lesão do MR. Métodos Trata-se de um estudo transversal, com 235 pacientes obesos (índice de massa corporal [IMC] 30 kg/m2). Dados demográficos (idade e gênero), metabólicos (hipertensão, diabetes mellitus, perfil lipídico, e tempo de exposição à obesidade), exame físico (peso, estatura, circunferência abdominal, e testes clínicos), e exame ultrassonográfico musculoesquelético foram utilizados para a análise dos resultados. Resultados Não foi evidenciada associação da lesão do MR com IMC (p » 0,82), tempo de exposição à obesidade (p » 0,29), ou circunferência abdominal (p » 0,52). No subgrupo com lesão, a idade (p < 0,001), a presença de diabetes melito (p » 0,013), a hipertensão (p < 0,001), o nível de lipoproteína de alta densidade (high-density lipoprotein, HDL, em inglês) (p » 0,026), e o tempo de exposição à obesidade (p < 0,001) foram significativamente maiores em comparação ao subgrupo sem lesão do MR. Na busca por demais parâmetros associados de forma independente para lesão do MR, foram observadas associações com idade (p » 0,0003) e hipertensão (p »0,004). Conclusão Não evidenciamos associação da obesidade e do tempo de exposição a ela coma ocorrência e a gravidadeda lesãodo MR. Porém, indivíduos comlesão apresentaram maior tempo de exposição à obesidade e prevalência de disfunções metabólicas do que indivíduos sem lesão. Além disso, nossos achados sugerem uma associação entre hipertensão arterial sistêmica (HAS) e idade avançada com a lesão do MR.

Isokinetic Evaluation of the Shoulder After Bristow/Latarjet Surgical Procedure in Athletes.

Objectives To evaluate the muscular strength of the internal (IR) and external (ER) rotators of the shoulder after Bristow/Latarjet surgery. Methods Cross-sectional study with 18 patients (36 shoulders). The isokinetic evaluation was performed using the Biodex 3 System Pro dynamometer (Biodex Medical System, Inc., Shirley, NY, USA). The athletic shoulder outcome rating scale (ASORS) and the visual analogue scale (VAS) were applied. Results The values of peak torque and maximum work in concentric and eccentric mode on the non-operated shoulder were higher than on the operated side for both the IR and ER ( p < 0.01). The conventional and functional balance between the ER and IR showed no differences between the operated and the non-operated side. When comparing patients with postoperative time < 1 year or 1 year, no differences were observed in peak torque values at 60°/s and 240°/s and maximum work at 60°/s and 240°/s of the IR to the operated shoulder. However, the peak torque values of 60°/s and 240°/s and maximum work at 60°/s and 240°/s of the ER were higher in subjects with postoperative time ≥ 1 year in all variables ( p < 0.05). Conclusions There was a decrease in the strength of the IR and ER in the operated shoulder compared with the healthy shoulder. However, the conventional and functional balance was maintained.

Resumo Objetivos Avaliar a força muscular dos rotadores medial (RM) e lateral (RL) do ombro após cirurgia de Bristow/Latarjet. Métodos Estudo transversal com 18 pacientes (36 ombros). A avaliação isocinética foi realizada por meio do dinamômetro Biodex 3 System Pro (Biodex Medical System, Inc., Shirley, NY, EUA). A escala de avaliação dos resultados do ombro do esportista (EROE) e a escala visual analógica (EVA) da dor foram aplicadas. Resultados Os valores do pico de torque e o trabalho máximo no modo concêntrico e excêntrico no ombro não-operado foram maiores que no lado operado, tanto para o RM e como para o RL (p< 0,01). O equilíbrio convencional e funcional entre o RL e o RM não apresentou diferenças entre o lado operado e o não operado. Na comparação entre pacientes com o tempo pós-operatório < 1 ano ou ≥ 1 ano, não se observou diferenças nos valores do pico de torque em 60°/s e 240°/s e do trabalho máximo em 60°/s e 240°/s do RM para o ombro operado. No entanto, os valores de do pico de torque em 60°/s e 240°/s e do trabalho máximo em 60°/s e 240°/s do RL foram superiores em indivíduos com tempo pós-cirúrgico ≥ 1 ano em todas as variáveis (p< 0,05). Conclusões Houve diminuição da força do RM e do RL no ombro operado em relação ao ombro saudável; porém, o equilíbrio convencional e funcional foi mantido.
