Overall outcome better with THA vs hemiarthroplasty in elderly with hip fracture .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2014;2(15):22 PLoS One. 2014 May 22;9(5):e98071. doi: 10.1371/journal.pone.0098071.8 randomized controlled trials (n=983) were included in this meta-analysis comparing outcomes between total hip arthroplasty and hemiarthroplasty in elderly patients. Results indicated significantly higher Harris Hip scores and a significantly lower risk of revision in the total hip arthroplasty group when compared to hemiarthroplasty. There was, however, a trend towards a higher rate of dislocation for total hip arthroplasty, although not statistically significant. The most common complication requiring revision surgery was acetabular erosion. As a whole, total hip arthroplasty appeared to be favoured over hemiarthroplasty in this population.

L'indice de fragilité est un outil qui aide à l'interprétation des résultats significatifs, en fournissant une mesure de la force d'un résultat. L'indice de fragilité représente le nombre d'événements consécutifs qui doivent être ajoutés à un résultat dichotomique pour que le résultat ne soit plus significatif. Un petit nombre représente un résultat plus faible et un grand nombre un résultat plus fort.
Pourquoi cette étude était-elle nécessaire maintenant ?
Fractures of the femoral head are becoming increasingly prevalent with the aging population. Treatment options include internal fixation, hemiarthroplasty, and total hip arthroplasty. The latter two options are preferred over internal fixation, due to the associated risks of nonunion, avascular necrosis, and mechanical failure with fixation. However, the optimal method between the two arthroplasty techniques for elderly individuals remains controversial, emphasizing a need for this meta-analysis.
Quelle était la principale question de recherche ?
How do hemiarthroplasty and total hip arthroplasty compare in elderly patients?
- Harris hip scores (HHS) were reported in 5 studies. Pooled results significantly favoured total hip arthroplasty over hemiarthroplasty at 1 year (SMD: -7.11 [95% CI -10.70 to -3.53]; p<0.05) and 2 years postoperatively (SMD:-6.91 [95% CI -12.98 to -0.85]; p<0.05).
- Dislocation rate was measured in 6 studies; 5 studies were pooled (n=691). Results indicated a non-significant trend towards a higher rate for total hip arthroplasty (33/390) compared to hemiarthroplasty (14/421), (RR: 0.46 [95% CI 0.21-1.02]; P = 0.06; I-squared = 14%) with low heterogeneity.
- Revision rates were reported in 5 studies, and pooling demonstrated a higher revision rate for hemiarthroplasty (32/352) compared to total hip arthroplasty (11/321) (RR: 2.58 [95% CI 1.04-6.40]; P=0.04; I-squared = 19%), with low heterogeneity.
- Complications resulting in revision surgery for hemiarthroplasty were most commonly acetabular erosion, followed by periprosthetic fracture, acetabulum osteoarthritis, and deep infection. For total hip arthroplasty, the most common was infection, followed by femoral stem subsidence, acetabulum osteoarthritis and dislocation.
- Heterogeneity in reporting of surgical time, blood loss and transfusion did not allow for pooling.
De quoi dois-je me souvenir en priorité ?
Total hip arthroplasty was associated with significantly higher Harris Hip scores and a lower risk for revision, while hemiarthroplasty resulted in a lower dislocation rate. The most common complication for total hip arthroplasty was infection, whereas acetabular erosion was highest in hemiarthroplasty.
Comment cela affectera-t-il les soins prodigués à mes patients ?
As a whole, the results from this analysis suggest total hip arthroplasty may hold benefits over hemiarthroplasty in elderly patients with a femoral head fracture. Patients treated with total hip arthroplasty appeared to enjoy better hip outcomes and lower revision rates. Trials with longer follow-up and assessment of health-related quality of life outcomes are recommended to add to this body of literature. Addtionally, further research should consider possible methods of reducing dislocation rates for those undergoing total hip arthroplasty.
