Patient characteristics in dislocations after primary total hip arthroplasty:60 patients compared with a control group

Patient-related risk factors for early revision of total hip replacements: A population register-based case-control study of 674 revised hips

“…Irrespective of the amount of alcohol, our findings indicated an increased risk for revision due to dislocation among patients drinking alcohol. A similar relationship between alcohol and dislocation has been suggested by Hedlundh and Fredin (1995). We observed no overall association between smoking and revision risk, but former heavy smokers ran a significantly higher revision risk than did the never-smokers.…”

Do Large Heads Enhance Stability and Restore Native Anatomy in Primary Total Hip Arthroplasty?

“…Several patient factors have been associated with an increased risk of dislocation, including age older than 75 years, acute femoral neck fracture, failure of previous proximal femoral fracture, developmental dysplasia, and rheumatoid arthritis [9,18,21,24,26,29,41]. Three hundred seventy-nine (18.8%) of the hips were deemed high risk for dislocation based on these risk factors and none sustained a dislocation.…”

“…For the entire period of the study, large heads were used in 73.2% of primary THAs (2020 of 2758). Three hundred seventy-nine (19%) hips were deemed at high risk for dislocation based on age older than 75 years or diagnosis of developmental dysplasia, failure of previous proximal femoral fracture, acute femoral neck fracture, and rheumatoid arthritis [9,18,21,24,26,29,41]. Surgical approach for the majority of cases was direct lateral, used in 1815 of the 2020 (90%) hips, including the less invasive variant introduced in 2003 [2] in 1260 (62%), standard incision in 546 (27%) hips [15], and extended variant in nine (0.4%) hips [15].…”

“…Reported incidence ranges from less than 1% to 5% with a recent Medicare claims data analysis of 58,521 patients reporting 3.9% dislocation in the first 26 weeks postoperative [31]. Numerous patient factors may contribute to increased dislocation risk: aging, female gender, lower muscular disorders, cognitive dysfunction, dysplasia, previous femoral neck fracture, and rheumatoid arthritis [9,18,21,24,26,29,41]. The correlation between higher surgeon and hospital volume and lower dislocation rates has also been established [20].…”

Do Joint Registries Report True Rates of Hip Dislocation?

“…Dislocation remains a common and clinically important complication with a reported incidence varying widely from 0.3% to 15% [1,2,12,15]. The functional and financial consequences are often underestimated [3,16] and dislocation is associated with a higher incidence of mortality compared with a nondislocating cohort [5].…”
