Abstract:
Studies describe progression of adjacent joint arthritis after hip fusion but not vise versa. We investigated the relationship after spinopelvic fusion and total hip arthroplasty. 383 patients undergoing spinopelvic were investigated. Perioperative demographics were recorded. A matched 2:1 cohort was used to detect risk factors for THA progression. 10 patients (2.6%) underwent THA after spinopelvic fusion. Average time from surgery to THA was 24.4 months. After spinopelvic fusion, patients progressed to THA 24.4 months on average. Due to small numbers, we couldn't find differences between the two groups regarding comorbidities nor risk factors for THA. Further studies are needed.

Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are...
