Application of internal fixation for injuries of pelvic anterior ring through minimally invasive ilioinguinal approach / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the reliability of limited open reduction and minimally invasive plate osteosynthesis (MIPO) for injuries of pelvic anterior ring and to explore its operative techniques and therapeutic efficacy.</p><p><b>METHODS</b>From March 2009 to March 2012,20 patients with injuries of pelvic anterior ring were surgically fixed with reconstructive plates through minimally invasive ilioinguinal approach. There were 13 males and 7 females with an average age of 41.6 years ranging from 25 to 61 years. According to classification of Tile, there were 5 cases of type A2, 2 cases of type B1, 9 cases of type B2, 1 case of type B3, 3 cases of type C1. Including 15 cases with anterior ring fracture, 2 cases with anterior ring fracture combined with pubic symphysis separation, and 3 cases with anterior and posterior fractures. Operation time, intra-operative blood losing, injuries of femoral nerve and iliac blood vessels, condition of fracture reduction were observed.</p><p><b>RESULTS</b>All wounds healed at one stage. No complications such as infection or deep venous thrombosis occurred. According to Matta criterion of fracture reduction, 12 cases got excellent results, 7 good, 1 fair. Eighteen patients were followed up from 6 to 32 months with a mean of 16.3 months. According to functional score of Majeed, 15 cases obtained excellent results and 3 good,with an average score of 94.3 +/- 6.0.</p><p><b>CONCLUSION</b>The modified ilioinguinal approach has advantage of short operation time, less blood losing,minimally invasive in treating injuries of pelvic anterior ring and can obtain satisfactory outcomes.</p>
