    Cement-within-cement technique in revision reverse total shoulder arthroplasty: complications, reoperations, and revision rates at 5-year mean follow-up
    (Elsevier Inc., 2025) Marinis Acle, Rodrigo Ignacio de; Sperling, John W.; Marigi, Erick M.; Velasquez Garcia, Ausberto; Wagner, Eric R.; Sanchez-Sotelo, Joaquin
    Background: Revision reverse total shoulder arthroplasty (rTSA) of a previously cemented humeral component is challenging. In hip arthroplasty, the cement-within-cement (CwC) technique has been well described as an effective option. However, for shoulder arthroplasty there remains a paucity of data investigating this technique. The purpose of this study was to determine the mid-term outcomes of patients who underwent a revision rTSA utilizing the CwC for management of the humeral component. Methods: Between 2005 and 2021, 68 revision rTSA using the CwC technique with a minimum of 2 years clinical follow-up were identified from a single institution joint registry database. Revised implants consisted of 38 (55.9%) hemiarthroplasties, 22 (32.4%) anatomic total shoulder arthroplasties, and 8 (11.8%) rTSA. A total of 12 (17.6%) shoulders required an osteotomy (corticotomy or window) to assist with extraction of the cemented stem. The mean follow-up after revision was 5.4 years (range, 2-16 years). Surgical complications, reoperations, revisions, and implant survivorship were assessed. Results: Of the 12 shoulders that required an osteotomy for component removal, 11 (91.7%) were healed. At final follow-up, the overall complication rate was 26.9%. The most common complication was fracture or fragmentation of the greater tuberosity (20.6%, n = 13) with 10 (76.9%) cases showing signs of healing at final follow-up. The overall survivorship free of revision surgery was 88.2% at 2 and 80.9% at 5 years, respectively. The most frequent causes of re-revision surgery were aseptic glenoid component loosening (n = 4) and instability (n = 4), with only 2 (2.9%) patients developing humeral component loosening (at 2 and 5 years, respectively). Male sex was associated with an increased risk of revision surgery (hazard ratio [HR], 3.52 [95% confidence interval [CI] 1.22-10.18]; P = .02) and complications (HR, 3.56 [95% CI, 1.40-9.07]; P = .008). The grade of postoperative lucent lines at the humerus (HR, 1.35 [95% CI, 1.04-1.74]; P = .02) and glenoid (HR, 1.59 [95% CI, 1.22-2.10]; P = .001) also correlated with an increased risk of re-revision surgery. Conclusion: The CwC technique is a reliable option for revising previously cemented humeral components in revision rTSA. Although a low rate of humeral component loosening was observed, higher rates of complications and re-revision surgery were observed over time secondary to aseptic glenoid component loosening and instability, which are not directly related to CwC technique but to revision surgery in general.

    Current Clinical Applications of Artificial Intelligence in Shoulder Surgery: What the Busy Shoulder Surgeon Needs to Know and What’s Coming Next
    (2023) De Marinis Acle Rodrigo Ignacio; Marigi, Erick M.; Atwan, Yousif; Yang, Linjun; Oeding, Jacob F.; Gupta, Puneet; Pareek, Ayoosh; Sanchez-Sotelo, Joaquin; Sperling, John W.
    Artificial intelligence (AI) is a continuously expanding field with the potential to transform a variety of industries -including healthcare- by providing automation, efficiency, precision, accuracy, and decision-making support for simple and complex tasks. Basic knowledge of the key features as well as limitations of AI is paramount to understand current developments in this field and to successfully apply them to shoulder surgery. The purpose of the present review is to provide an overview of artificial intelligence within orthopedics and shoulder surgery exploring current and forthcoming AI applications.

    Venous Thromboembolism Following Surgical Management of Proximal Humerus Fractures: A Systematic Review
    (2023) Marigi, Erick M.; Sperling, John W.; Marinis Acle, Rodrigo Ignacio de; Gupta, Puneet; Hassett, Leslie C.; Soza Rex Jose Francisco; Sánchez-Sotelo, Joaquín
    Currently, there is limited information on the incidence of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE) after surgical treatment of proximal humerus fractures (PHFs). Therefore, the purpose of this systematic review is to evaluate the incidence of VTE, DVT, and PE following surgery for PHFs.
