[A case-control study of preserving the shape of iliac bone and traditional iliac osteotomy]

To compare and study the traditional iliac bone extraction and iliac crest preserving bone extraction, and to observe their curative effects.

From January 2016 to December 2018, 50 patients were treated with traditional iliac bone extraction and iliac crest preserving iliac bone extraction, with 25 cases in each group. In the traditional iliac bone extraction group, there were 18 males and 7 females, aged (42.0±7.9) years, hospitalized for (20.0±5.5) days and followed up for (13.68±1.60) months. There were 16 males and 9 females in the iliac crest preserving osteotomy group, aged (44.0±8.2) years, hospitalized for (21.0±6.5) days and followed up for (14.04±1.54) months. The operation time, intraoperative bleeding, postoperative pain visual analgue scale(VAS), fracture healing and complications were recorded and compared between the two groups.

In the traditional iliac bone extraction group, the operation time was (16.20±2.51) min, the amount of bleeding was (63.20±17.73) ml, the VAS score on the first day after operation was 4.72±1.21, and the fracture healing time was (4.84±0.90) months. In the iliac crest preserving osteotomy group, the operation time was (16.24±3.00) min, the amount of bleeding was (62.80±18.14) ml, the VAS score was 4.80±1.29 on the first day after operation, and the fracture healing time was (4.68±0.80) months. There was no significant difference in operation time, bleeding volume, pain VAS on the first day after operation and fracture healing time between the two groups(P>0.05).

Compared with the traditional iliac bone removal surgery, this bone removal method of preserving the appearance of iliac bone is simple and convenient. While ensuring the amount of bone removal, it retains the appearance of iliac crest as much as possible and reduces local discomfort symptoms after operation. It is worth popularizing.
