RESUMO
This study presented a pioneering investigation of the changes in the magnetic resonance imaging images of pectoralis major muscle (PMM) tendon rupture. In all, 26 men were evaluated with acute total PMM rupture (<3 months since injury) with a mean age of 37.3 years (SD = 9.7 years) and 10 control patients with a mean age of 32.6 years (SD = 4.2 years). The evaluation of the tendon PMM injuries was based on the magnetic resonance imaging exam and the histological analysis. The magnetic resonance imaging of the surgically showed two (7.1%) contralateral sides were normal, 16 (57.1%) showed superior tendinopathy, and 10 (35.7%) had total tendinopathy. Inferior tendinopathy was not observed. The tendon histology revealed degenerative changes in 16 (66.7%) fragments, with 12 (50.0%) considered as mild (<25%), and four considered as (16.7%) high (>50.0%) tendinopathy. Total acute rupture of the PMM tendon among weightlifters might be associated with tendinous degeneration prior to injury.
RESUMO
To compare outcomes between autologous fascia lata and autologous hamstring grafts for chronic pectoralis major muscle (PMM) rupture repair, and perform histological, and imaging analyses. Forty male patients with chronic PMM ruptures (time since injury ranging from >3 months to 5 years) and a mean age of 37.3 years (SD = 9.7 years) were evaluated. One group (20 patients) received an autologous semitendinosus graft, and another group (20 patients) received an autologous fascia lata graft for PMM reconstruction. These patients with fascia lata grafts by Bak 2criterium 60% of the patients presented excellent results, 20% presented good results, 15% presented fair results, and 5% presented poor results. In the hamstring group 65% of the patients presented excellent results, 30% presented good results, and 5% presented fair results. In this comparative study, no difference was observed regarding the functional result, image, and histology between groups.
RESUMO
The distal rupture of the biceps brachii muscle tendon (DBT) accounts for 3% of biceps ruptures. Diagnosis typically relies on high clinical suspicion and complementary imaging studies, with >90% of cases documented in males between the fourth and sixth decades of life. Reports of DBT ruptures in females are scarce, mostly involving partial and degenerative injuries. Here, we present an unprecedented case of a 28-year-old female professional mixed martial arts athlete with a total traumatic DBT rupture. The athlete underwent surgical repair using anchor reattachment technique. No complications were observed, and the athlete showed satisfactory outcomes, being cleared for physiotherapy after 2 weeks and returning to sports after a 3-month postoperative period.
RESUMO
Pectoralis major muscle tendon ruptures associated with physical activity or effort are no longer uncommon in the medical literature. Treatment has also evolved significantly in the last 20 years. However, simultaneous bilateral rupture has only been described in a few cases. This article reports three cases with simultaneous bilateral rupture and describes the examinations and treatment performed. Bilateral lesions, although infrequent, also require early diagnosis and treatment in the acute phase. The chronic phase requires tendon grafting for full correction and a slow rehabilitation process.
RESUMO
Background: Although there is a low incidence of shoulder instability in women, this population is still representative and is often associated with lower rates of return to sports. Few studies have evaluated the results of the Latarjet procedure in this population. Methods: This was a prospective cohort study of female athletes who underwent the Latarjet procedure between 2013 and 2018. The participants were followed up for 3 years. The primary outcomes of the study included the visual analog scale for pain; range of motion: active elevation, passive elevation, active external rotation, and passive external rotation. The functional scores were as follows: American Shoulder and Elbow Surgeons score, the Western Ontario Shoulder Instability Index, and the Athletic Shoulder Outcome Rating Scale. Additional data were collected regarding return to sport, complication rates, and patient satisfaction. Results: Thirteen female athletes who practice Soccer, Volleyball, Basketball, Handball, Judo, or Weight training were evaluated. There was a significant reduction in the mean range of motion for all movements at 4 weeks after surgery. Patients recovered a range of motion similar to the preoperative values after 6 months. The mean visual analog scale reached 6.39 at the first week after surgery and decreased to values below preop at 8 weeks. The mean preoperative Western Ontario Shoulder Instability Index was 126.77 (min 118; max 135), and at the end of follow-up, the WOSI index was 45.08 (min 37; max 65; P < .05). The mean preoperative American Shoulder and Elbow Surgeons score was 41.61 (min 35; max 46), and at the end of follow-up, the mean ASES score was 84.46 (min 80; max 90; P < .05). The mean Athletic Shoulder Outcome Rating Scale in the preoperative period was 39.38 (min 37; max 42), and at the end of follow-up, the mean ASORS score was 83.15 (min 77; max 85; P < .05). The rate of return to sports was 92.3%, and 84.6% of patients were satisfied with the surgery. The aesthetic satisfaction rate was 76.9%. The complication rate was 15.4% (1 screw failure and 1 dislocation recurrence). Conclusion: Latarjet surgery in female athletes showed high rates of return to sports and improved functional scores without impairing range of motion after the procedure. Recurrence and complication rates were low. In addition, treatment was associated with improved functionality and patient satisfaction.
RESUMO
Rotator cuff tears (RCT) is a multifactorial disease with genetic factors contributing for the disease etiology. We hypothesized that genetic variants in genes involved in extracellular matrix (ECM) homeostasis may alter susceptibility to RCT. We evaluated 20 polymorphisms of genes involved in ECM homeostasis in 211 cases of full-thickness tears of the supraspinatus (Nfemales = 130; Nmales = 81) and 567 age-matched controls (Nfemales = 317; Nmales = 250). Multivariate logistic regressions were carried out with age, gender, genetic ancestry (based on the analysis of 61 biallelic short insertion/deletion polymorphisms), and common co-morbidities (diabetes, dyslipidemia, and smoking habits) as covariates. We observed that carriers of the rare allele of both studied variants of TGFB1, as well as their G/A (rs1800470/rs1800469) haplotype, were less susceptible to RCT (p < 0.05). In contrast, carriers of the G allele of MMP9 rs17576 (p = 0.014) or G/G haplotype (rs17576/rs17577; p < 0.001) had an increased risk for tendon tears. The presence of the T allele of MMP2 rs2285053 (p = 0.033), the T allele of MMP3 rs679620 (p = 0.024), and the TT-genotype of TIMP2 rs2277698 (p = 0.01) was associated with susceptibility to tears, especially in females. In males, the A allele of COL5A1 rs3196378 (p = 0.032) and the G allele of TGFBR1 rs1590 (p = 0.039) were independent risk factors for RCT. The C/T COL5A1 (rs3196378/rs11103544) haplotype was associated with a reduced risk of tears in males (p = 0.03). In conclusion, we identified the genetic variants associated with RCT susceptibility, thereby reinforcing the role of genes involved in the structure and homeostasis of the ECM of tendons in disease development. © 2019 Orthopaedic Research Society.

Frozen shoulder is a condition of loss of active and passive motion as result of inflammatory contracture and fibrosis of the joint capsule. We hypothesize that genetic variants in genes involved in these processes such as genes that play a role in extracellular matrix homeostasis (collagens, glycoproteins, genes involved in TGFß signaling, and metalloproteinases and its inhibitors) may contribute to the susceptibility to frozen shoulder. We evaluated eighteen SNPs of genes involved in extracellular matrix homeostasis in 186 cases (Nfemales = 114; Nmales = 72) of frozen shoulder and 600 age-matched controls (Nfemales = 308; Nmales = 292). Multivariate logistic regressions were carried out with age, gender, genetic ancestry, and common comorbidities as covariates. Carriers of the C allele of MMP13 rs2252070 and G/G MMP9 (rs17576 A>G/rs17577 G>A) haplotype may have an increased risk of frozen shoulder (p = 0.002, OR = 1.64, 95%CI = 1.20-2.26, and p = 0.046, OR = 1.40, 95%CI = 1.01-1.95, respectively), especially in females (p = 0.005, OR = 1.91, 95%CI = 1.22-2.99, and p = 0.046, OR = 1.59, 95%CI = 1.01-2.51, respectively). In females, the G allele of MMP9 rs17576 tended to contribute to the susceptibility to the studied disease (p = 0.05, OR = 1.51, 95%CI = 0.97-2.33). In contrast, the presence of the C allele of TGFB1 rs1800470 seems to be associated with a reduced risk (p = 0.04, OR = 0.47, 95%CI = 0.23-0.96) while the GG-genotype of TGFBR1 rs1590 was associated with increased risk (p = 0.027, OR = 4.11, 95%CI = 1.17-14.38) to frozen shoulder development in males. Thus, we identified genetic variants that were independent risk factors that can aid in the risk assessment of frozen shoulder reinforcing the involvement of MMP and TGFß signaling in disease development. © 2019 Orthopaedic Research Society.

In the last years, shoulder injuries have represented an increasing health problem in soccer players. The goalkeepers are more exposed to shoulder disorders than other field players. Injury prevention exercises for upper limbs were cited in few studies involving throwing athletes, but we know that goalkeepers need a specific program. The purpose of this study is to describe the development of an adapted Fédération Internationale de Football Association (FIFA) 11+ program, namely the FIFA 11+ shoulder, which targets the prevention of shoulder injuries in soccer goalkeepers. The FIFA 11+ shoulder program is structured into three parts: general warming-up exercises, exercises to improve strength and balance of the shoulder, elbow, wrist, and finger muscles, and advanced exercises for core stability and muscle control. The exercises were selected based on recommendations from studies demonstrating high electromyographic activity.
RESUMO
BACKGROUND: The aim of this study was to describe epidemiological data and evaluate the clinical results of traumatic anterior glenohumeral instability in rodeo athletes. METHODS: Thirteen patients, all male, with a mean age of 23.2 (18-31) years old, with anterior glenohumeral instability were include in this study. In 9 patients, the right side was affected. The mean time elapsed between injury and undergoing surgery was 56 months (24-120 months). The surgical technique used (arthroscopic or open bone block procedure) was chosen based on the ISIS (Instability Severity Index Score). Only professional athletes who had been in the sport for at least 60 months were included. Functional evaluation was conducted using the UCLA scale, after a 24-month follow-up period. RESULTS: The number of dislocation episodes varied from 10 to 100 (mean 27 episodes). All of the patients were submitted a surgical treatment open bone block procedure, due to their degree of sport participation, type of sport (forced overhead and collision) and the presence of associated bone defect lesions. According to UCLA criteria, the results were excellent in 12 patients and good in one. The mean time elapsed before returning to the sport was five months, varying between two and ten months. Complications included one patient developing axillary neuropraxia, which was completely resolved six months after the operation, and another patient developed a superficial skin infection. CONCLUSIONS: The rodeo athletes with anterior shoulder instability had serious associated bony lesions and has good outcome after bone block procedure.

BACKGROUND: Tears of the rotator cuff tendons, which surround the joints of the shoulder, are one of the most common causes of pain and disability in the upper extremity. OBJECTIVES: To review the efficacy and safety of common interventions for tears of the rotator cuff in adults. SEARCH STRATEGY: We searched the Cochrane Bone, Joint and Muscle Trauma Group specialised trail register (July 2002), the Cochrane Controlled Trials Register (The Cochrane Library issue 2, 2002), MEDLINE (1966 to December 2001), EMBASE (1974 to December 2001), Biological Abstracts (1980 to December 2001), LILACS (1982 to December 2001), CINAHL (November 1982 to December 2001), Science Citation Index and reference lists of articles. We also contacted authors and handsearched conference proceedings focusing on shoulder conditions. SELECTION CRITERIA: Randomised or quasi-randomised clinical trials involving tears of the rotator cuff were the focus of this review. All trials involving conservative interventions or surgery were included (non-steroidal anti-inflammatory drugs, intra-articular or subacromial glucocorticosteroid injection, oral glucocorticosteroid treatment, physiotherapy, and open or arthroscopic surgery). DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed suitability for inclusion, methodological quality and extracted data. Dichotomous data were presented as relative risks (RR) and 95% confidence intervals (CI), using the fixed effects model. MAIN RESULTS: Eight trials involving 455 people were included and 393 patients analysed. Trials were grouped in eight categories of conservative or surgical treatment. The median quality score of all trials combined was 16 out of a possible 24 points, with a range of 12-18. In general, included trials differed on diagnostic criteria for rotator cuff tear, there was no uniformity in reported outcome measures, and data which could be summarised were rarely reported. Only results from two studies comparing open repair to arthroscopic debridement could be pooled. There is weak evidence for the superiority of open repair of rotator cuff tears compared with arthroscopic debridement. AUTHORS' CONCLUSIONS: There is little evidence to support or refute the efficacy of common interventions for tears of rotator cuff in adults. As well as the need for further well designed clinical trials, uniform methods of defining interventions for rotator cuff tears and validated outcome measures are also essential.

PURPOSE: The purpose of this study was to compare the functional results of arthroscopic treatment for traumatic anterior shoulder instability in 2 groups of athletes. METHODS: Fifty patients were randomly assigned to 2 different groups with comparable patient demographics. Group A was treated with anchors loaded with absorbable sutures, and group B was treated with the same type of anchors loaded with nonabsorbable sutures. The same type of absorbable anchor, surgical technique, and rehabilitation protocol was used in both groups. The outcomes were evaluated after a minimum postoperative period of 24 months. The Rowe score and the Athletic Shoulder Outcome Scoring System were applied, and statistical analysis was performed. RESULTS: The mean Rowe score was 83.8 in group A and 79.5 in group B. The mean values for the Athletic Shoulder Outcome Scoring System were 84 and 79.2, respectively. Good or excellent results were found in 90.5% of patients in group A and 87.5% in group B. We had 2 failures (9.5%) in group A and 3 (12.5%) in group B. No statistically significant difference was found in the comparison of the outcomes (P > .05). CONCLUSIONS: The type of suture used, absorbable or nonabsorbable, did not influence the functional results of arthroscopic treatment for traumatic anterior shoulder instability in this series.

Os autores avaliaram 119 atletas com queixas relacionadas à região do ombro, dos quais 95 (79,8 por cento) eram do sexo masculino, 71 (59,6 por cento) arremessadores e 76 (63,8 por cento) competitivos. O membro dominante foi acometido em 76 (66,3 por cento) dos casos. As lesões traumaticas foram mais frequentes nos esportes de contato e as lesões traumaticas nos atletas arremessadores. Os esportes com maior incidencia de lesão associada foram o volei, com 14 (11,7 por cento) atletas, seguido da natação, com 13 (10,9 por cento) e jiu-jitsu, com 11 (9,2 por cento). O seguimento medio dos atletas foi de nove meses e seis dias. A queixa de dor estava presente em 86 (72,2 por cento) atletas. O mecanismo atraumatico, com 66 (55,4 por cento) casos, foi mais frequente, seguido dos traumas diretos, com 37 (31 por cento), e dos traumas indiretos, com 16 (13,6 por cento). O tipo de lesão mais frequente foi a luxação, com 32,7 por cento, seguido das tendinites, com 31 por cento. As afecções relacionadas a instabilidade do ombro, com 48 casos (40 por cento), foram mais frequentes, seguidas das relacionadas ao manguito rotador, com 38 (31,9 por cento), e das acromioclaviculares, com 22 (18,5 por cento). O retorno ao esporte ocorreu em media apos sete semanas; 89 (74,8 por cento) atletas retornaram ao mesmo nivel de competição e 24 (20,2 por cento) diminuiram seu desempenho; seis (5 por cento) não voltaram ao esporte
