Effect of vertical and lateral offset restoration on clinical outcomes in intracapsular and extracapsular hip fractures undergoing hemiarthroplasty
Özet
Objective
We aimed to investigate whether there is a change in the postoperative lateral and vertical femoral offset
(FO) in patients who underwent bipolar straight stem hemiarthroplasty (SSHA) and calcar stem
hemiarthroplasty (CRHA) and whether this change makes a difference in the comparison of both groups.
Material and methods
This study included 109 patients who met these criteria. Patients are divided into two groups according to
treatment methods. There were 58 patients (group 1) who underwent SSHA due to intracapsular (AO type 31-
B neck and 31-C head fracture) femur fracture, and there were 51 patients (group 2) who underwent CRHA
due to extracapsular (AO type 31-A intertrochanteric) femur fracture. We analyzed femoral vertical and
lateral femoral offset, Wiberg angle, and head-neck angle difference in both groups.
Results
The median age was significantly higher in the CRHA group (p=0.042). The Harris hip score (HHS) was
significantly higher in the SSHA group (p=0.023). The femoral offset difference was 5 mm in the SSHA group,
while it was significantly lower (-6 mm) in the CRHA group (p<0.001). The Wiberg angle difference did not
differ significantly between patient groups (p=0.214). The limb length difference was found to be similar in
both surgical groups (p=0.483).
Conclusions
The study results show that there was no negative correlation between clinical and radiological outcomes in
the SSHA group, whereas there was a negative correlation between clinical and radiological outcomes in the
CRHA group. It is very difficult to control vertical and lateral offset reconstruction, especially in
extracapsular hip fractures reconstructed by hemiarthroplasty. Deficiencies in lateral and vertical
stabilization restoration may be associated with poor clinical outcomes in CRHA patients. Orthopedic
surgeries should be performed carefully when restoring leg length and femoral offset, especially calcar
replacement hemiarthroplasties.
