BACKGROUND: Recent scientific work shows that the most common injuries in CrossFit© occur in the shoulder joint. This paper aims to provide a review of shoulder pathologies in a young CrossFit© cohort via MRI and clinical examination. METHODS: A survey was conducted in 13 CrossFit "boxes" in Germany, in which athletes with recurrent shoulder pain could report for a clinical examination and MRI diagnostic. Fifty-one CrossFit athletes with chronic shoulder pain agreed to participate in the study and were then examined physically and by MRI. RESULTS: Fifty-one active CrossFit athletes aged 21-45 years (mean 33.7 years, 35 male and 16 female) were recruited. The most frequently detected pathologies were partial lesions of the supraspinatus tendon (N.=25; 49%) and labral lesions (N.=11; 21.6%). The findings also identified partial lesions of the subscapularis tendon (N.=9; 17.6%), pulley lesions (N.=9; 17.6%), and partial lesions of the infraspinatus muscle (N.=2; 3.9%). CONCLUSIONS: These data demonstrate the need for a specific focus on particular shoulder injuries in CrossFit. Knowledge about the type of shoulder pathologies caused by CrossFit training allows for training-specific adaptations with regard to prevention, as well as a more targeted, sport-specific therapy. This study is the first in the literature to present on structural changes in the shoulders of active CrossFit athletes.

Shoulder arthrodesis and resection arthroplasty can be used as salvage procedures to treat severe complications after shoulder prosthesis failure. for both procedures, the indication and patient selection must be very strict. Shoulder arthrodesis after prosthesis failure can be indicated in young patients in case of chronic neuromuscular dysfunction. Filling the bony defect with either autologous or allogenic material and osteosynthetic primary stability are decisive for a good functional outcome. Aftercare comprises immobilization for 12 weeks and physical load is increased thereafter, depending on the sufficiency of bony consolidation. Resection arthroplasty after shoulder prosthesis failure is mostly reserved for multimorbid patients in case of a chronic infection. Thorough debridement and adequate systemic antibiotic treatment are crucial to achieve bacterial eradication.

PURPOSE: Hardly any other topic is as current as the gender-conscious medical treatment of every individual. Similarly, in sports, there are crucial differences that should be considered in order to treat everyone appropriately, with the aim to prevent injuries according to their needs. The objective of this study is to show that the differences between biological males and females are so significant that they require both specific injury prevention and therapy programs. METHODS: This study is a retrospective analysis of letters from a department of orthopedics and trauma surgery between the years 2000 and 2015. RESULTS: The analysis of 20,567 inpatient and outpatient letters of a level 1 trauma center in Germany revealed that 5455 patients suffered 7279 injuries; 1475 of the patients were female and suffered 2035 injuries, and 3890 patients were male and suffered 5244 injuries. CONCLUSION: The results show the differences between males and females with regard to sport-specific injuries, pointing out the sex differences in the sport-specific area in relation to the body region.
