Subacromial

BACKGROUND: Emerging evidence has indicated the associations between subacromial impingement syndrome (SIS) of shoulder and lifestyle factors. However, whether unhealthy lifestyle factors causally increase SIS risk is not determined. This study aims to evaluate whether lifestyle factors are the risk factors of SIS. METHODS: A two-sample Mendelian randomization (MR) study was designed to evaluate the effect of 11 lifestyle factors on SIS risk. Causality was determined using the inverse-variance weighted method to calculate the odds ratio (OR) and establish a 95% confidence interval (CI)...

BACKGROUND: The coactivation (Co-A) of shoulder muscles that contribute to humeral head depression can lead to mechanical unloading of the subacromial structures during abduction and thus can be beneficial for patients with arthroscopic rotator cuff repair (ARCR). The present study aims to examine the effectiveness of humeral head depressor muscle Co-A (DM-Co-A) training on clinical outcomes in a sample of patients with ARCR. HYPOTHESIS: We hypothesized that DM-Co-A training with medioinferior vector during glenohumeral exercises can improve clinical results in the rehabilitation of ARCR...

The massive irreparable rotator cuff tear remains a challenging condition for which there are many reported treatment options including biceps tenotomy/tenodesis, subacromial decompression, cuff debridement, partial or augmented rotator cuff repair, bursal acromial reconstruction, balloon spacer placement, superior capsular reconstruction (SCR), reverse total shoulder arthroplasty (RSA), tendon transfer, and others. Optimally treating the condition relies on paying attention to several patient factors, including correctly identifying if function loss is driven by pain or compromised shoulder kinematics...

RATIONALE AND OBJECTIVES: To determine the diagnostic accuracy and reproducibility of conventional MR imaging (MRI) of the shoulder in evaluating biceps pulley lesions using arthroscopy as the standard of reference. METHODS: In a retrospective study, MR examinations of 68 patients with arthroscopically proven torn or intact biceps pulley were assessed for the presence of pulley lesions by three radiologists. The following criteria were evaluated: displacement of the long head of the biceps tendon (LHBT) relative to the subscapularis tendon (displacement sign), subluxation/dislocation of the LHBT, the integrity of the superior glenohumeral ligament (SGHL) and the coracohumeral ligament (CHL), lesions of the supraspinatus (SSP) and subscapularis (SSC) tendons adjacent to the rotator interval, presence of biceps tendinopathy and subacromial bursitis...

Rotator cuff injuries are a major cause of shoulder pain, affecting the quality of life and producing a significant burden on healthcare systems. Conservative management modalities are prioritized, resorting to surgery only when required. The field of regenerative medicine involving the use of biologics, such as platelet-rich plasma (PRP), has evolved and shown potential for managing rotator cuff injuries. Nonetheless, limitations including subpar outcomes have led clinicians to question the efficacy of autologous PRP...

Chronic rotator cuff injuries (CRCIs) still present a great challenge for orthopaedics surgeons. Many new therapeutic strategies are developed to facilitate repair and improve the healing process. However, there is no reliable animal model for chronic rotator cuff injury research. To present a new valuable rat model for future chronic rotator cuff injuries (CRCIs) repair studies, and describe the changes of CRCIs on the perspectives of histology, behavior and MRI. Sixty male Wistar rats were enrolled and underwent surgery of the left shoulder joint for persistent subacromial impingement...

BACKGROUND: One proposed mechanism of rotator cuff disease is scapular motion impairments contributing to rotator cuff compression and subsequent degeneration.
