Does total hip replacement using the posterior approach improve outcomes in active, healthy patients with displaced femoral neck fractures?
Total hip replacement via a posterior approach in active, healthy older patients with displaced femoral neck fractures yields good functional outcomes and high satisfaction, with a 6.7% dislocation rate.

Posterior approach THA shows notable dislocation risk in this series; leaves open its role versus alternatives in active femoral neck fracture patients.
Treatment of displaced femoral neck fractures with total hip replacement (THR) in appropriately selected patients has become more widely accepted. The use of the posterior approach for THR remains controversial due to concerns regarding dislocation, the cause of which is multi-factorial. This study is a single surgeon series of 45 consecutive active, healthy patients (mean age 78 years) with displaced femoral neck fractures treated with THR through a posterior approach. Large diameter heads (32mm in 47%, ≥36mm in 48% of patients) and an anatomic posterior soft tissue repair were utilised to minimize the risk of dislocation. Outcomes were reported at a mean of 2 and 6 years. The mortality rate was 13% at 2 years and 40% at 6 years. All revision surgery (4.4%) was performed for dislocations which occurred in 6.7% of patients. Good VAS pain, OHS and SF-12 scores were reported both at 2 and 6 years. Patient satisfaction with the results of surgery was high.

Low et al. (2012) conducted an observational in Displaced femoral neck fractures (n=45). Total hip replacement using the posterior approach was evaluated on Dislocation. Total hip replacement using a posterior approach for displaced femoral neck fractures in active, healthy patients resulted in a 6.7% dislocation rate and a 4.4% revision rate.
