Purpose: To analyze the results of a posterior minimal incision approach in primary total hip arthroplasty.
Materials and Methods: Twenty hips, inserted by the posterior minimal invasive approach (group Ⅱ), were matched with the same number of hips, inserted via the traditional posterior approach (group Ⅰ), The incision lengths, operative times, blood losses, periods of admission, postoperative rehabilitation times, complications, and positions of the acetabular cups and femoral stems were compared between groups Ⅰand Ⅱ.
Results: The average incision lengths in groups Ⅰ and Ⅱ were 16.1 cm(range, 14~19.5 cm) and 9.2cm ( range, 7.5~10.3 cm), respectively (p<0.05). The average operative times were 83.2 minutes (range, 65~110 minutes) and 70.4 minutes (range, 60~100 minutes) in groups Ⅰ and Ⅱ, respectively (p>0.05), which initially was longer in group Ⅱ, but this time because shorter with experience. The average blood losses were 965 ml (range, 3~14 days) and 12.5 days (range, 8~18 days) and 5.5 days (range, 3~10 days) in groups Ⅰ and Ⅱ, respectively (p<0.05). The postoperative positions of the acetabular cups and femoral stems were satisfactory in all cases, with no complications observed in any of the cases.
Conclusion: The posterior minimal incision approach in primary total hip arthroplasty has the advantages of a smaller incision and a shorter rehabilitation time.
