ObjectiveTo discuss feasibility of minimal-invasive surgical treatment of the pelvis fractures.MethodsTwenty-six patients with pelvis fractures were treated by micro-surgical treatment. There were 15 male and 11 female with an average age of 40 years ranging from 20 to 62 years. All patients were closed fractures, 17 patients were hemi-pelvis fractures, 9 patients were bilateral-pelvis fractures. The fracture type of posterior ring of pelvis as follows:8 patients were sacro-iliac joint dislocation, 12 patients were vertical section fractures in the outboard of the sacrum. The fracture type of anterior ring of pelvis as follows: 9 patients were hemi-fracture of rami ossis pubisi or hemi-fracture of rami ischi, 7 patients were bilateral-fracture of rami ossis pubisi or bilateral-fracture of rami ischii, 6 patients were separation of symphysis pubis. Six patients accompanied with shock. Anterior ring of pelvis was fixation by lag screw via superior ramus of pubis and pubic symphysis; Posterior ring of pelvis was fixation by lag screw via sacroiliac joint or intrasacral rod via ilium. X-ray films and multi-slice spiral CT of pelvis was obtained in order to understand exterior and inner details about pelvis fractures. Adopt orientation in body and inducted by C-arm digital subtracting X-ray system when operating.ResultsBlood loss was about 10 to 50 ml (mean 30 ml). Operation time was 30 to 50 minutes. Time of fracture union was 8 to 12 weeks (mean 11 weeks). Wound infection, ununion of fracture and nerve injuries had not been found.ConclusionMinimally invasive operation has the merit of short operation time, fine effect, soon recovering and few complication.
