Abstract:
Objective To investigate the efficacy of absorbable screw rod system in the treatment of posterior hip dislocation complicated with femoral head fracture.Methods Between February 2009 and June 2014,20 patients were treated at our department for posterior hip dislocation complicated with femoral head fracture.They were 14 males and 6 females,with an average age of 38.2 years (range,from 27 to 60 years).Eight left hips and 12 right hips were affected.By the Pipkin classification,15 cases were type Ⅰ and 5 type Ⅱ.The time from injury to surgery ranged from 3 to 14 days (average,6 days).All of them were treated with absorbable screw rod system after Allis manual reduction.Results The operation time in this group ranged from 1 to 6 hours (average,1.8 hours).The intraoperative blood loss ranged from 70 to 400 mL (average,160 mL).They were followed up for 18 to 48 months (average,32 months).All the fractures united after an average time of 3.4 months (range,from 2.5 to 5.0 months).According to the Harris scores at 6 months postoperation,10 cases were rated as excellent,7 as good,2 as fair and one as poor,with a good to excellent rate of 85.0％.Total hip replacement was performed for 2 fair and one poor cases because their postoperative pain was not relieved and femoral avascular necrosis developed.Conclusion Absorbable screw rod system is an effective treatment of posterior dislocation with femoral head fracture,because it can simplify operative procedures,reduce trauma,fixate the fracture firmly,avoid secondary operation,and reduce postoperative complications.
