ABSTRACTObjective: To evaluate radiographically the periprothesical radiolucent zones in those patients taken part surgically by hemiarthroplasty of cemented shoulder. Material and methods: It was made a cross-sectional study of 25 patients operated of hemiarthroplasty of cemented shoulder bypolar modulate type with glenohumeral arthritis of any etiology, age and sex, to those who a radiological evaluation for the identification of radiolucent periprothesical zones was made to them, defining to a humeral component on “radiological risk” for the clinical loss of the same one, when the lines of radiolucent periprothesical zones were greater of 2 mm in 3 or more zones. It was carried out statistical descriptive with measures of central tendency and dispersion for the demographic and radiologic variables. Results: The prevalence of the disease was of the 0,4% of the total of orthopaedic consultations of first time, the age average was of 61.7 ± 12.49 (rank 32-85 years), feminine and masculine sex 8.6% and 91.4%; the most frequent etiology was the degenerative one with 45.8%, the side but affected he was left the 54.3%. With a pursuit of 19 ± 8,6 months, in the radiological evaluation was identified that the 20.8% of the patients presented “radiological risk”; whereas single the 4.2% of them did not have line of radiolucent zones.
