[Modified Stoppa approach in treatment of bilateral pubic branch fractures]

To investigate the feasibility and effectiveness of modified Stoppa approach in treatment of bilateral pubic fractures of pelvic.

The therapeutic effects of 16 patients with bilateral pubic fractures treated through the modified Stoppa approach from January 2010 to January 2014 were summarized and analyzed, involved 11 males and 5 females with an average age of 40.5 years old ranging from 17 to 59 years. According to Tile classification, there were 8 patients with type A, 6 with type B and 2 with type C. For 16 pelvic fractures, the modified Stoppa approach was used exclusively 11 cases, in combination with the iliac fossa approach in 4 cases, and in combination with the posterior approach in 1 case. The operation incision length, operation time , intra-operative blood loss and postoperative complications were observed. The fracture reduction and post-operative function were assessed by Matta criteria and Majeed system respectively.

The incision length of the modified Stoppa approach ranged from 8 to 10 cm (averaged in 9 cm). The operation time ranged from 75 to 135 minutes (averaged in 95 minutes). The intra-operative blood loss ranged from 400 to 900 ml (averaged in 600 ml). Sixteen patients were followed up from 7 to 18 months (averaged in 12.5 months). The fractures were all healed, the fracture healing time was 2.7 to 5 months (means 3.1 months). There were no infections, ectopic ossification, screw loosening, plate breakage and lateral ventral syndrome. According to Matta criteria for pubic fracture reduction, the result was excellent in 9 cases, good in 6, fair in 1. The Majeed function scores at 6 months after operation was 85.32±8.50; the result was excellent in 8 cases, good in 6 cases, fair in 2 cases.

The modified Stoppa approach has characteristics of convenience and directness of incisions, clear operation field, easy reduction, few complications and fast recovery , it is an ideal choice in surgical treatment of bilateral pubic fractures.
