“…We also want to note that when the acromioclavicular joint is not affected, avoiding shortening of the acromion during surgery is paramount to preserve AC joint biomechanics. 19 With this intention, we preserved cortices during resection and did not apply compression with the screws. Maintaining acromial length has an additional benefit by keeping the tension of the coracoacromial ligament.…”

Purpose Os acromiale is a common entity in the middle-age group, in whom it is frequently associated with rotator cuff tears. However, it can be a cause of shoulder pain in the young athletes. We want to increase awareness of this pathology that may occultly affect the young athlete as well as to present the results of a perfusion-preserving arthrodesis. Methods Four consecutive young patients (17-21 years old) with a history of at least 6 months of unrecognized shoulder pain were surgically treated for os acromiale. Through a superior approach, stabilization of the neo-joint by means of cannulated screws and autogenic graft augmentation was performed. Results Union of the os acromiale was achieved in all the patients. They had an excellent functional outcome, reaching all the maximum Simple Shoulder Test (12) and Oxford shoulder Score (48) scores. All the patients were able to return to their previous sports level. Conclusion Awareness of the os acromiale in the young athlete, appropriate clinical examination, and image studies are crucial to confirm diagnosis. Surgical treatment aiming at fusion in situ has shown excellent result.

“…However, AC joint osteoarthritis is a constant finding during a clinical and instrumental examination of the shoulder; in fact, in their series, Shubin Stein et al 2001and Tauber et al (2016), documented that degenerative changes of AC joint were present in 93% of subjects over 30 years and almost 100% in the over fifties. These data seem to suggest a multifactorial etiology of AC osteoarthritis.…”

AC joint osteoarthritis: The role of genetics. An MRI evaluation of asymptomatic elderly twins

et al. 2020

Purpose The anatomy of the articular surfaces has historically identified as major responsible for acromioclavicular joint osteoarthritis (ACJO). On the other side, the almost 100% prevalence of ACJO in subjects over 50 years old seems to suggest a multifactorial etiology. We compared ACJO between asymptomatic elderly monozygotic (MZ) and dizygotic (DZ) twins to investigate the influence of genetics and environmental factors. Materials and Methods Thirty pairs of twins [15MZ‐15DZ; mean age (SD): 63.70 (3.31); range: 53–72] were retrospectively enrolled. ACJO was evaluated on MRI through a 4‐grade severity scale and ACJ configuration was assessed. Information regarding work activity were obtained. Heritability index was calculated. Results The intraclass correlation coefficient (ICC) value of 0.868 (95% CI; 0.798 to 0.917). An ICC values of 0.889 (95% CI; 0.798 to 0.944) and 0.843 (95% CI, 0.712 to 0.920) were found in the MZ and DZ groups, respectively. The polychoric correlation was 0.857 in the MZ twins and 0.757 in the DZ twins. The calculated heritability index was 0.20 (20%), and the contribution of the shared environment (c2) and unique environment (e2) was 0.66 (66%) and 0.14 (14%), respectively. No relationship between job types and ACJO in both the total cohort (r = 0.089; p = 0.499) and in the monozygotic (r = 0.247; p = 0.187) and the dizygotic twin groups (r = −0.084; p = 0.658) was found. Conclusions The role of genetics on ACJO accounts for only 20%; a specific anatomical configuration of the articular surfaces only partially acts on the development of joint osteoarthritis. Environmental factors have the greatest impact. Level of Evidence: IV.

“…L'incidence des modifications radiologiques de l'AC augmente avec l'âge. Les modifications dégénératives de l'AC sont retrouvées chez 68% des patients de moins de 30 ans, 93% audelà de 30 ans et environ 100% après 50 ans [2][3][4][5][6]. Seul l'âge présente une corrélation forte avec la dégénérescence de l'AC [2,3,6], même si les activités physique et professionnelle peuvent accélérer ces phénomènes.…”
