INTRODUCTIONPeriprosthetic humerus fractures are infrequent and sometimes difficult to treat. There is limited literature and no consensus on the handling of these fractures. The objective of this study was to compare our results with those published in the literature, in order to improve our care and propose a management algorithm. MATERIAL AND METHODObservational study of 10cases of periprosthetic humerus fractures with a mean follow-up of the patients of 23months. An analysis of sociodemographic, radiological and surgical variables was performed. They were reviewed clinically and by telephone using the UCLA Shoulder Score and Quick-DASH scales. A systematic search was made in Pubmed for periprosthetic humerus fractures, for a literature review with which to compare our series. RESULTSWe analysed 10patients with an average age of 69.4years (37-91). Of the patients, 90% underwent surgery through open reduction and internal fixation. Nine of the ten patients consolidated in a mean time of 6.2months (range 5-12), the remaining suffered a new fracture 5months after the intervention, who were reoperated and a new osteosynthesis performed with bone allograft. In the UCLA scale there was a decrease of 10.66points, and an increase of 27.3points in the Quick-DASH, at the end of the follow-up. CONCLUSIONSIn our series of cases we found similarities in the literature, in relation to demographic aspects and obtaining good radiographic results, which do not correspond to the functional outcome of patients.
