Abstract:
Objective To discuss the clinical effects of transverse screw fixation of double columns in crescent pelvic fractures.Methods Twenty patients with crescent pelvic fractures hospitalized from December 2012 to December 2015 were reviewed retrospectively.There were thirteen male and seven female patients with the age ranging from 22 to 72 years (mean,39.5 years).Causes of injury were traffic accidents in fifteen patients,falling from high places in three and hitting by heavy objects in two.Time interval between injury and operation was 3-14 d.According to the Orthopedic Trauma Association (OTA) classification,all were classified as 61-B2 type.Reconstruct plate was used to stabilize the supperior pubic ramus fractures,and transverse double-column fixation with anterograde or retrograde screws was used for the posterior iliac crescent fractures.Duration of inserting screws,operation time,intraoperative blood loss and frequency of C-arm X-ray were recorded.Radiological and clinical outcomes were evaluated after operation.Results Duration of inserting screws ranged from 3 to 16 min (mean,5 min).Operation time ranged from 50 to 130 min (mean,80 min) and the intraoperative blood loss ranged from 200 to 550 ml (mean,280 ml).Frequency of C-arm X-ray in the surgery ranged from 1 to 5 times (mean,2 times).All screws were in the expected location,without any piercing out of the iliac bone dependent on the confirmation of X-ray and CT-scan after operation.According to the Matta and Tornetta radiological evaluation,the reduction was rated excellent in sixteen patients and good in four,with the excellent-good rate of 100％.There was no death,wound infection,sciatic nerve or superior gluteal nerve injury or deep venous thrombosis of lower extremities.At the followup,no nonunion,loss of reduction,and breakage of internal fixation occurred.Nineteen patients were followed up,and mean follow-up time was 19.6 months (range,3 to 36 months).Union was obtained in all patients in a period of 8-17 months (mean,11.2 months).According to the Majeed functional evaluation at the final follow-up,the outcome was rated excellent in seventeen patients and good in two,with the excellent-good rate of 100％.Conclusion Transverse screw fixation of double columns in crescent pelvic fracture of 61-B2 type can reduce the operation injury,decrease complications,and have good clinical results.
