ABSTRACT
Objective To observe the effect and its factors of open reduction and internal fixation of calcaneal fractures,and the influencing factors.Methods A retrospective analysis of 116 cases of calcaneal fracture were made.All patients were treated with open reduction and internal fixation,the effect was evaluated by Maryland foot score.The relation of the data before surgery (sex,age,cause of injury,associated injuries,injury and surgery,frac-tures sanders classification,opening and closing,diabetes,smoking history)and the effect,the surgical data (graft case,fixation,fractures,postoperative Bohler angle)and the effect were analyzed.The independent factors of the effect were analyzed by Logistic regression analysis.Results 116 patients with calcaneal fracture had been followed up for 6 -12 months,the excellent -good rate of Maryland foot score was 74.14%.Univariate analysis showed that different types of fractures,open and closed,with or without diabetes,with or without a history of smoking,different fixation methods,different fractures,patients with different postoperative Bohler angle foot function excellent rate differences were statistically significant (χ2 =17.194,4.077,6.766,9.116,5.136,6.919,4.458,all P <0.05).Logistic regres-sion analysis showed that the type of fracture,fixation,fractures,postoperative Bohler angle were independent risk factors for foot function excellent rate(OR =0.052,0.048,0.056,0.386,all P <0.05).Conclusion It has exact efficacy for open reduction and internal fixation with calcaneal fractures,the fracture type,fixation,fractures,postoper-ative Bohler angle are independent risk factors for affecting the calcaneal fractures patients.Perioperative treatment should take appropriate measures to avoid adverse factors affecting the efficacy of improved clinical efficacy.
ABSTRACT
[Objective] To investigate the surgical method of transforminal lumbar interbody fusion(TLIF)technique in treatment of upper lumbar intervertebral disc herniation.[Methods]From January 2002 to December 2006,a retrospective analysis on TLIF surgery treatment of 45 patients with upper lumbar intervertebral disc herniation were carried out and they acquired 12~24 months(mean,15 months)follow up.There were 29 males,and 16 females aging from 30~55 years(mean,39.2 years).Eleven intervertebral spaces were T12-L1 hernination,25 intervertebral spaces were L1、2 hernination,and 18 intervertebral spaces were L2、3 hernination of the space.Nine were double disc herniation.All cases were treated with TLIF technique.A retrospective analysis on surgical therapeutic effect was made.[Results]Five patients developed complications after operation and recovered by symptomatic treatment.Patients moved around in 2~3 d after surgery.Oswestry score improved from(52.32 ?9.17)to(20.33 ?5.72)in an average 15-months follow-up.X-ray showed that all cases had bone graft fusion and no adjacent segment degeneration occurred.[Conclusion]TLIF technique is an effective method in treatment of upper lumbar intervertebral disc herniation.It can offer satisfactory clinical effects.
