ObjectiveTo summary the effects of staged pelvic closure using external fixator combined with reconstruction plate for old Tile B1 pelvic fracture.MethodsFrom August 2000 to August 2006, 14 patients (9 males and 5 females, age ranging from 21 to 65 years with old Tile B1 pelvic fracture with pubic symphysis separation were treated. The injuries were caused by the traffic accident in 10 patients, high crash in 3, and crush in 1. The duration ranged from 4 weeks to 3 months. The 14 patients were complicated with other injuries in some degrees. The X-ray and CT showed pubic symphysis separation. In 13 patients, pubic symphysis separation distance was more than 2.5 cm, who also had fracture or dislocation in the posterior structure of pelvis. The X-ray films showed the mean pubic symphysis separation distance was (6.67 +/- 2.11) cm preoperatively. The 14 patients underwent pelvic external fixation at first and staged pelvic closure gradually for the pubic symphysis separation. After 2 to 3 weeks, when the pubic symphysis separation distance was less than 1 cm, the patients underwent open reduction and internal fixation with reconstruction plate. Pubic symphysis separation distance was measured in the preoperative and postoperative pelvic anterioposterior X-ray films. The condition of the posterior structure of pelvis was observed in CT films. The functions of patients were assessed according to Majeed grading system.ResultsAll incisions healed by first intention. The 14 patients were followed up for 6 months to 2 years (15 months on average). The X-ray films showed the mean pubic symphysis separation distance of post-operation was (0.85 +/- 0.23) cm, showing statistically significant difference when compared with that of pre-operation (P < 0.05). The CT films showed fracture and dislocation of the posterior structure of pelvis had bony healing after 6 to 12 months. According to the Majeed grading system, the results were excellent in 5 cases, good in 4 cases, fair in 4 cases and poor in 1 case; the excellent and good rate was 64.29%.ConclusionStaged pelvic closure using external fixation combined with reconstruction plate for old pelvic fracture with pubic symphysis separation can reduce the pubic symphysis separation distance significantly. Satisfactory effects can be expected in treating the patients with Tile B1 fracture.
