ABSTRACT Rotator cuff tears (RCT) is a multifactorial disease with genetic factors contributing for the etiology. We hypothesized that variants in genes involved extracellular matrix (ECM) homeostasis may alter susceptibility to RCT. evaluated 20 polymorphisms of ECM 211 cases full‐thickness supraspinatus ( N females = 130; males 81) and 567 age‐matched controls 317; 250). Multivariate logistic regressions were carried out age, gender, ancestry (based on analysis 61 biallelic short...

However, previous Brazil other countries have been characterized by large variations design data collection methods as well definitions injury, standardized diagnostic criteria, recovery times.A system developed Union European Football players being used starting point...

OBJECTIVES:We evaluated mRNA expression levels of genes that encode TGF-b1; the TGF-b1 receptor; collagen-modifying enzymes LOX, PLOD1, and PLOD2; extracellular matrix proteins COMP, FN1, TNC TNXB in synovial/capsule specimens from patients with idiopathic adhesive capsulitis.Possible associations between measured clinical parameters were also investigated.METHODS: We obtained glenohumeral joint synovium/capsule 9 capsulitis who had not shown improvement symptoms after 5 months...

Traumatic anterior shoulder instability is a common disease, especially in young athletes. The Latarjet and Bristow techniques are nonanatomical surgeries that involve the transfer of coracoid process to border glenoid indicated cases at high risk for recurrence presence associated bone lesions. Studies have evaluated complications with these techniques, but they important differences, should not be considered synonymous. objective this study was prospectively compare high-demand Hypothesis:...

Rotator cuff tear is a common orthopedic condition. Metalloproteinases (MMP) and their inhibitors (TIMP) seem to play role in the development of joint injuries failure tissue healing. However, mechanisms regulation gene expression tendons are still unknown. Epigenetic mechanisms, such as DNA methylation microRNAs regulation, involved dynamic control expression. Here, mRNA status MMPs (MMP1, MMP2, MMP3, MMP9, MMP13, MMP14) TIMPs (TIMP1-3) miR-29 family members ruptured supraspinatus were...

Frozen shoulder is a condition of loss active and passive motion as result inflammatory contracture fibrosis the joint capsule. We hypothesize that genetic variants in genes involved these processes such play role extracellular matrix homeostasis (collagens, glycoproteins, TGFβ signaling, metalloproteinases its inhibitors) may contribute to susceptibility frozen shoulder. evaluated eighteen SNPs 186 cases (Nfemales = 114; Nmales 72) 600 age-matched controls 308; 292). Multivariate logistic...

Abstract To compare outcomes between autologous fascia lata and hamstring grafts for chronic pectoralis major muscle (PMM) rupture repair, perform histological, imaging analyses. Forty male patients with PMM ruptures (time since injury ranging from &amp;gt;3 months to 5 years) a mean age of 37.3 years (SD = 9.7 were evaluated. One group (20 patients) received an semitendinosus graft, another graft reconstruction. These by Bak 2criterium 60% the presented excellent results, 20% good 15% fair...

Rotator cuff tear is one of the most common causes shoulder dysfunction. Gene expression analysis may be a useful tool for understanding tendon tears and failure healing, reverse-transcription quantitative polymerase chain reaction (RT-qPCR) has become an effective method such studies. However, this technique requires use suitable reference genes data normalization. Here, we evaluate suitability six (18S, ACTB, B2M, GAPDH, HPRT1 TBP) using samples from rotator tendons 28 individuals with (3...

Prospective study 27 male patients with a mean age 29.9 (SD = 5.3 years) and follow-up 2.3 years. The procedure consisted autologous grafts taken from semitendinosus gracilis tendons Patients were evaluated functionally by Bak criteria. surgical treatment was performed in early stages (three weeks) six (22.2%) 21 (77.8%), late stages. operated button obtained 96.3%...

O ombro doloroso é uma queixa muito comum entre os atletas, especialmente no caso dos arremessadores. As lesões parciais do manguito rotador podem ser dolorosas e causar limitação funcional importante na pratica esportiva atleta. A incidência das variável (13% a 37%). diagnóstico clínico radiológico difícil deve considerado em todo atleta que apresente sintomatologia da síndrome rotador, inclusive nos pacientes diagnosticados apenas com tendinopatia. Avaliar o comportamento epidemiológico...

A painful shoulder is a very common complaint among athletes, especially in the case of those sports involving throwing. Partial lesions rotator cuff may be and cause significant functional limitation to athletes’ practice. The incidence partial variable (13–37%). It difficult make clinical radiological diagnosis, this condition should borne mind cases all athletes who present symptoms syndrome, including patients are diagnosed only with tendinopathy. To evaluate epidemiological behavior...

ABSTRACT The molecular alterations involved in the capsule deformation presented shoulder instability patients are poorly understood. Increased TGFβ1 acts as a signal for production of matrix macromolecules by fibrogenic cells at joint injury sites. TGFβ1, through its receptor TGFβR1, regulates genes collagen cross‐linking, such LOX, PLOD1, and PLOD2. We evaluated LOX , PLOD1 PLOD2 gene expression antero‐inferior (macroscopically injured region), antero‐superior posterior regions...
