Abstract :
Background: Total hip arthroplasty (THA) is regarded as the most
successful and common surgical approach in orthopedic surgeries. Several
surgical approaches have been described for THA to introduce minimally
invasive surgical exposures. Posterolateral and lateral approaches are
traditional and still most commonly used approaches for primary THA. In
deciding which approach to use, consideration of complications, and
clinical and radiological outcomes, using one approach or another should
be evaluated. Objectives: The purpose of this study was to compare the
early postoperative outcomes of posterolateral and lateral surgical
approaches. Patients and Methods: The current study was conducted on a
group of 134 primary hip arthroplasty of 120 patients who had undergone
THA surgery at Shafa Orthopedic Hospital in Tehran, Iran, from March
2011 to October 2014. The lateral approach was used in 79 hips and,
posterolateral approach was used in 55 hip based on surgeon’s
preference. Two groups were assessed considering the following outcomes:
clinical evaluation including Harris hip score (HHS), blood loss, blood
transfusion, hemoglobin level, infections, deep vein thrombosis (DVT)
and dislocation, as well as radiological evaluation including the
proximal femur fracture, limb length discrepancy and cup inclination
angle. The follow-up for both groups was at 6, 12, 24, 36 and 48 weeks
after the surgery. Results: There was no significant difference between
the two approaches regarding demographic characteristics, HHS, blood
loss, transfusion, hemoglobin level, dislocation and cup inclination
angle. However, there was a significant difference in the incidences of
infections, DVT, proximal femur fracture and discrepancy of limb length
between the two approaches. Conclusions: The results of this study
indicate that both lateral and posterolateral approaches offer similar
early clinical outcomes and some different radiological outcomes.
