Reverse shoulder arthroplasty for proximal humeral fracture in the elderly. Cemented or uncemented stem? Int Orthop. 2022 Mar;46(3):635-644. doi: 10.1007/s00264-021-05284-y. Epub 2022 Jan 16.

Methods: Retrospective review of 68 primary RSAs in PHF, 45 cemented/23 uncemented. Functional outcomes were evaluated according to constant, ASES scales and the range of motion (ROM). Radiographic assessment was performed at a minimum of two years post-operatively. Results: The mean follow-up cemented/uncemented was 37.8/26.5 months (p = .04) and the mean age 78/80 years old (p = .09). The functional outcome and range of movement were equivalent in the two groups except for the forward flexion that was significantly higher in the cemented group (p = .03). Stress shielding was seen in 30.4% of uncemented group and none in the cemented. Anatomic tuberosity healing was significantly higher with uncemented components compared with cemented components (64% vs 91%, p = .02). Cemented stems had radiolucent lines with a width of 2 mm or more in three or more Gruen zones in 9% vs 0% in the uncemented group and an evident change in the stem position was present in 4% vs 0% in the non-cemented group. Conclusion: At mid-term follow-up, no differences in functional outcomes were detected depending on the stem fixation technique. Cemented stems, however, have a complication rate (including stem loosening) significantly higher than press-fit stems.engjournal articlehttps://doi.org/10.1007/S00264-021-05284-Yhttps://link.springer.com/article/10.1007/s00264-021-05284-yrestricted access617.57CementedHumeral prosthesisLooseningLucencyPress-fitProximal humeral fracturesRadiological outcomeReverse shoulder arthroplastyShoulder functionUncementedSistema musculoesquelético3213.15 Traumatología
