Background:
Developmental dysplasia of the hip is a common disease and treated with various surgical approaches. Improved ilioinguinal (I-I) approach, two-incision Smith-Peterson (TSP) approach, and modified Smith-Peterson (MSP) approach are three main approaches; however, they are rarely compared. The present study compared the operative time, blood loss, intraoperative and postoperative allogeneic blood transfusion, and postoperative complications of these three different approaches.
Hypothesis:
Surgical approach does not influence the operation time, blood loss, and complications of periacetabular osteotomy.
Level Of Evidence:
Level III. Case-control study.
Patients And Methods:
In a total of 101 hips of 95 cases, from February 2010 to July 2011, three different approaches of Bernese periacetabular osteotomy, I-I, TSP, and MSP, were conducted. The operation time, intraoperative bleeding, allogeneic blood transfusion, and early complications in different operation approaches were compared by a retrospective study when there were similar ages, genders, and lesions.
Results:
Among the three approaches, I-I had less operation time and more blood loss (P<0.05), TSP had less blood loss (P<0.05) but more complications, and MSP had less blood loss (P<0.05) and less complications.
Discussion:
The MSP approach is superior to the other two approaches in doing periacetabular osteotomy.
