Postoperative complications associated with congestive heart failure in aseptic revision total shoulder arthroplasty.

PURPOSE: The aim of this study is to explore potential complications and risk factors associated with revision TSA in patients with congestive heart failure (CHF). METHODS: This study examined all individuals who underwent revision total shoulder arthroplasty (TSA) from 2015 to 2022, sourced from the American College of Surgeons National Surgical Quality Improvement database. The analysis encompassed patient demographics, comorbidities, and 30-day postoperative complications. Logistic regression was employed to analyze the postoperative complications linked to patients with preoperative CHF. RESULTS: Compared to patients without CHF, patients with CHF were significantly associated with dependent functional status (P < .001), chronic obstructive pulmonary disease (P < .001), and hypertension (P = .002). Compared to patients without CHF, patients with CHF were independently associated with a significantly greater likelihood of experiencing any complication (OR 2.19, 95% CI 1.12-4.29; P = .022) and non-home discharge (OR 3.02, 95% CI 1.37-6.65; P = .006). CONCLUSION: Congestive heart failure was identified as an independent risk factor for experiencing any complication and non-home discharge in patients undergoing revision TSA. Awareness of the cardiovascular health status of a patient and its severity can influence the decision-making process when considering revision TSA.

Radiation in Adolescent Idiopathic Scoliosis Management: Estimated Cumulative Pre-Operative, Intra-Operative, and Post-Operative Exposure.

Background: Adolescent Idiopathic Scoliosis (AIS) is the most common type of scoliosis affecting adolescents, with approximately 2-4% of children being diagnosed. Crucial to the diagnosis and management are radiographic imaging, which allow physicians to assess and treat - from initial visits through surgical planning and post-operative management. While initial stages require low levels of exposure to radiation, via x-rays, as patients progress in disease severity exposure becomes larger with pre-operative, intra-operative and post-operative CT scans. While many studies have evaluated exposure during AIS treatment, few have assessed the cumulative radiation exposure adolescents receive during their evaluation. The purpose of our study is to complete a comprehensive review on cumulative radiation exposure and determine what stages in AIS treatment expose patients to the highest level of radiation over a duration of 2 years. Methods: A retrospective chart review of 109 AIS cases (29M, 80F), mean age 14.9 ± 2.3 years was completed to assess and quantify each imaging modality used. Employing a radiation detector, each imaging modality was then assessed, and estimated radiation exposures were determined. Statistical analysis was completed utilizing averaged patient exposures during each selected period in AIS management. Results: Mean estimated radiation doses (StDev) were 60.94 mrem (±0.609 mrem) for two x-rays (full-length AP and lateral radiograph of the entire spine), 12.92 mrem (±1.292 mrem) for each fluoroscopy exposure, and 1340.60 mrem (±13.406 mrem) per CT scan. Based on these values, estimated subject exposures were calculated. The total estimated radiation exposure over a 2-year period was 5572.74 mrem (±1428.88 merm) or 2786.37 mrem (±714.43 mrem) per year. Conclusion: The two-year cumulative radiation exposure is below the recommended exposure by Nuclear Regulatory Commission and OSHA. As expected, CT exposure presents the largest radiation exposure to patients with AIS throughout their operative management. Level of Evidence: III, retrospective study.
