“…These results were corroborated by another systematic review of comparative studies by Reina et al, in which the dislocation rate for primary THA with DMC was 0.9% [46]. THA with DMC has also been compared to HA for the treatment of FNF, with the theory that the reduced dislocation risk with DMC would offset the increased risk seen with conventional THA compared to HA-this has been supported by several studies [47][48][49], while other studies show equivocal results [50,51]. Whereas the reports favoring DMC are promising, further prospective, randomized trials with longitudinal follow-up are needed to evaluate long-term results.…”

Hip fracture is a cause for concern in the geriatric population. It is one of the leading causes of traumatic injury in this demographic and correlates to a higher risk of all-cause morbidity and mortality. The Garden classification of femoral neck fractures (FNF) dictates treatment via internal fixation or hip replacement, including hemiarthroplasty or total hip arthroplasty. This review summarizes existing literature that has explored the difference in outcomes between internal fixation, hemiarthroplasty, and total hip arthroplasty for nondisplaced and displaced FNF in the geriatric population, and more specifically highlights the risks and benefits of a cemented vs. uncemented approach to hemiarthroplasty.

“…Owing to higher patients' satisfaction with THA than HA in case of displaced femoral neck fractures, the former is recommended in patients aged < 80 years and with a life expectancy of > 4 years. In patients aged > 80 years, both methods show equal results [1,25,4]. Age < 80 years is associated with higher dislocation rates than age > 80 years after HA [4].…”

Purpose Bipolar hemiarthroplasty has been shown to have a lower rate of dislocation than total hip arthroplasty. However, as the influencing risk factors for bipolar hemiarthroplasty dislocation remain unclear, we aimed to analyse patient and surgeon-specific influencing risk factors for bipolar hemiarthroplasty dislocation. Methods We retrospectively analysed patients who were operated between 2012 and 2018 and had dislocated bipolar hemiarthroplasty and matched them to patients without a dislocated bipolar hemiarthroplasty, operated between 2018 and 2019. The study was limited to patients who received either a pre- or postoperative pelvic computed tomography. Besides demographic, morphologic, and physiologic data, we analysed duration of surgery; ASA score; Charlson Comorbidity Index; Almelo Hip Fracture Score; Parker Score; and acetabular morphology angles including acetabular anteversion angle, posterior acetabular sector angle, posterior wall angle, and acetabular roofing. Results We included nine patients with a dislocated bipolar hemiarthroplasty and 30 with a non-dislocated bipolar hemiarthroplasty. Patient-specific factors prompting a higher risk for dislocated bipolar hemiarthroplasty were longer duration of surgery (min) (115 ± 50 vs. 80 ± 27, p = 0.01); dementia (56% vs. 13%, p < 0.01); smaller posterior acetabular sector angle (°) (96 ± 6 vs. 109 ± 10, p < 0.01); and smaller posterior wall angle (°) (67 ± 6 vs. 77 ± 10, p = 0.02). Conclusion Dementia and insufficient posterior wall angle were associated with higher risk of dislocation in bipolar hemiarthroplasty

“…This study showed equal rates of dislocation in both DM cups and BA (one patient in each group), which has been confirmed repeatedly in other studies. [16][17][18][19] However Ukaj et al 20 reported that DM cups have fewer dislocations than BA, and this was also confirmed by Syed et al 21 who performed a metanalysis of four studies that compared the rate of dislocation between DM cups and BA. Dislocation is a catastrophic complication in hip surgery.…”

Background:Bipolar hemiarthroplasty (BA) has long been the preferred treatment and is performed in most patients with femoral neck fracture (FNF). The dual mobility cup total hip arthroplasty (DMTHA) has emerged as a relevant alternative to BA. Since then there is an on-going debate on the best implant to use. Age, comorbidities, patient independence, and potential surgical complications must be considered when choosing implants. The risk of dislocation is a crucial factor because of its important consequences. The authors evaluated the functional and mechanical outcomes of BA versus DMTHA in FNF in active elderly patients. Methods:This study was a randomized comparative interventional singleblinded study that was performed at Ain Shams University Hospitals. A total of 33 patients underwent DMTHA or BA after displaced FNF. Primary outcomes were functional outcome and postoperative dislocation rate. Secondary outcomes were operative time and amount of blood loss. Results:There were no significant differences between the demographic data and preoperative parameters between the two groups. There was a significant difference in the postoperative Harris Hip Score (HHS) between the two groups (P = 0.01). VAS of groin pain was significantly different between the two groups (P < 0.001). There was no significant difference between the two groups regarding the dislocation rate. Conclusions:The authors concluded that DMTHA offered a better functional outcome than BA with no significant complications or mortality, and there was no significant difference between DMTHA and BA in the rate of dislocation.
