Key result
The lateral approach for hemi-replacement arthroplasty showed no significant difference in functional outcome at one year compared to the posterior approach (Modified Harris Hip score 83.78 vs 80.40, p=0.102).
Why the study?
Posterior approach results in better regain of function due to less muscle dissection, whereas lateral approach has a lower dislocation risk, prompting a comparison of their functional outcomes.
Does the lateral approach improve functional outcome compared to the posterior approach in elderly patients undergoing hemi-replacement arthroplasty for displaced neck of femur fracture?

Does the lateral approach improve functional outcome compared to the posterior approach in elderly patients undergoing hemi-replacement arthroplasty for displaced neck of femur fracture?
Absolute Event Rate: 83.78% vs 80.4%
p-value: p=0.102
There is no significant difference in functional outcomes or hip pain between lateral and posterior approaches for hemi-replacement arthroplasty in elderly patients with displaced femoral neck fractures, though the lateral approach had higher blood loss and the posterior approach had a higher risk of dislocation.
No takes yet. Share an insight, caveat, or question.
Both approaches yield equivalent one-year function after hemiarthroplasty; confirms equivalence and supports surgeon discretion in approach selection.
Kafle et al. (2022) conducted an RCT in Isolated traumatic displaced neck of femur fracture (n=50). Lateral approach vs. Posterior approach was evaluated on Modified Harris Hip score at one year (p=0.102). The lateral approach for hemi-replacement arthroplasty showed no significant difference in functional outcome at one year compared to the posterior approach (Modified Harris Hip score 83.78 vs 80.40, p=0.102).
