ABSTRACT
Objective To investigate the therapeutic effect of modified S-P approach without disconnecting the rectus femoris in patients with Pipkin typeⅠandⅡfractures. Methods The clinical data of 58 patients with Pipkin type Ⅰ and Ⅱfractures were retrospectively analyzed. Among the patients, 29 patients were treated with conventional S-P approach (conventional group), and 29 patients were treated with modified S-P approach (modified group). The incision length, operation time, bleeding, visual analogue score (VAS), postoperative complications and hip joint function at the final follow-up were compared between 2 groups. Results The patients of 2 groups had not incision infection, and showed primary. X-ray of 3 months after surgery showed fracture healing. There was no statistical difference in the time of follow-up between conventional group and modified group:(16.1 ± 5.2) months vs. (15.8 ± 5.6) months, P>0.05. The incision length, bleeding, VAS 3 d and 4 weeks after surgery in modified group were significantly lower than that in conventional group:(8.1 ± 0.8) cm vs. (12.3 ± 1.2) cm, (144.3 ± 16.5) ml vs. (172.4 ± 21.6) ml, (4.5 ± 1.1) scores vs. (5.9 ± 1.5) scores and (1.6 ± 0.7) scores vs. (2.4 ± 0.8) scores, and there were statistical differences (P0.05). Conclusions The modified S-P approach without disconnecting the rectus femoris is a better method in patients with Pipkin type ⅠandⅡ fractures, and it has the advantages of revealing more clearly, minimal invasion, lower bleeding and slight postoperative pain.
