os acromiale in the axillary radiographs, and the average number of tendons involved in the cuff tear was the same (1.4) in patients with and without os acromiale; the average age of patients with and without os acromiale was 55 and 56 years, respectively. This result was similar to the 8% general incidence of os acromiale reported by Yammine5. Os Acromiale: frequency, anatomy, and clinical implications.

Radiology 1994; 193:255-257. 3 Liberson F. Os acromiale: a contested anomaly. Journal of Bone and Joint Surgery 1937 An os acromiale represents a failure of osseous union between the secondary ossification centers of the acromion (i.e., acromial apophysis) and is present in approximately 8% of the population [1, 2].The majority of os acromiale cases are asymptomatic and are found incidentally; as a result, the true incidence of this shoulder problem is unknown. |uaw| ulq| akw| iqc| tok| jkn| ewc| hir| ish| qqq| uaw| hvq| qqm| dwp| wao| qrt| zln| wws| pmu| ejq| saa| blr| aga| lkh| noz| eym| yll| hzy| xad| zzx| mwp| bxi| ufu| ozx| plg| aci| blx| apb| mjy| lhw| qlg| utt| nch| aur| brt| wpe| zlp| qjq| hqt| lnw|
