The Effect of Strength Training on Undetected Shoulder Pathology in Asymptomatic Athletes: An MRI Observational Study.

BACKGROUND: Data on the effects of weight training on joint morphology are mostly restricted to muscle gain. However, in many circumstances, it is not stated if there are negative consequences for the joints and their surrounding components. This study was conducted to explore whether long-term excessive resistance training (RT) causes hidden pathological alterations in the shoulder. METHODS: A total of eleven asymptomatic sportsmen (22 shoulders) underwent clinical and radiological examination of both shoulder joints. All participants had engaged in bodybuilding for at least four years, at least three times per week, and for at least four hours per week. All participants were examined clinically using the Constant Murley Score (CMS), Simple Shoulder Test (SST), UCLA Activity Test, and a specially designed questionnaire. All participants received a bilateral shoulder MRI. The MRI scans were checked for pathology using a checklist. RESULTS: Maximum scores were observed for the SST and UCLA Activity Test. The CMS was 97.7 points on average (range, 87-100). RT had been conducted for a mean of 10.7 years (range, 4-20), for an average of 8.8 h a week (range, 4-12). MRI examinations revealed two supraspinatus tendinopathies (9.1%), one labral change (4.5%), three humeral tuberosity cysts (13.6%), fourteen acromioclavicular (AC) joint hypertrophies (63.6%), five AC joint osteophytes (22.7%), and ten signs of AC joint inflammation (45.5%). CONCLUSIONS: The research results show that strength is associated with MRI-documented AC joint pathology. However, it appears that RT may not negatively affect other anatomical structures of the shoulder.

The iTOP trial: Comparing immediate techniques of oncoplastic surgery with conventional breast surgery in women with breast cancer - A prospective, controlled, single-center study.

INTRODUCTION: Oncoplastic techniques allow resection of larger tumors, permitting breast conservation in cases otherwise requiring mastectomy. We sought to prospectively compare quality of life (QoL) in patients undergoing oncoplastic surgery as compared to conventional breast conservation (CBC) or mastectomy is lacking. METHODS: Patients diagnosed with BIRADS IV-VI lesion were eligible if resection of ≥10% of the breast volume was planned. Patients were allowed to decide whether they wanted to undergo CBC or oncoplastic breast conservation (OBC). Patients who underwent mastectomy and immediate breast reconstruction (IBR) were also included for comparison. The primary endpoint was breast self-esteem using the Breast Image Scale (BIS) at 12 months, secondary endpoints were perioperative morbidity and QoL using the BREAST-Q questionnaire. RESULTS: From 2011 to 2016, 205 patients were included in the study. 116 patients (56.6%) received CBC, 46 (22.4%) OBC and 43 (21%) MIBR. Women in the OBC group were more likely to have tumors ≥ 2 cm than those in the CBC group (34.7% vs. 17.5%, respectively). Women who underwent MIBR were more likely to have tumors > 5 cm than those in the CBC and OBC groups (23% vs 1% and 10%, respectively). The BIS and BREAST-Q improved in each group after 12 months but did not differ significantly between groups at any time point. Surgical complications (seroma, bleeding, infection, necrosis) were numerically more likely in the OBC and MIBR groups. CONCLUSION: OBC and the MIBR allow for resection of larger tumors with a similar quality of life as CBC.
