Objective To study the reconstruction method and effectiveness of titanium plate and Teflon patch for the chest wall after resection of sternal tumors. Methods Between October 2006 and November 2009, 4 patients with sternal tumors were treated and the thoracic cages were reconstructed. There were 2 males and 2 females, aged 30-55 years. The patientswere admitted because of chest lump or pain. The sizes of palpable lump ranged from 4 cm × 3 cm to 10 cm × 8 cm. CT examination showed bone destruction. After sternal tumor resection, defect size ranged from 10 cm × 8 cm to 18 cm × 14 cm, and titanium plate and Teflon patch were used to repair and reconstruct the chest wall defect. Results The operations of the tumor resection and reconstruction of chest wall defect were successfully performed in 4 cases. Incisions healed by first intention with no abnormal breath, subcutaneous emphysema, pneumothorax, and infection. One case failed to be followed up after 6 months; 1 case died of intracranial hemorrhage; and 2 cases were followed up 1 and 4 years respectively without tumor recurrence. The chest wall had good remodel ing. No loosening and exposure of titanium plate, difficulty in breathing, chest distress, and chest pain were observed during followup. Conclusion Surgical resection of sternal tumors will cause large chest wall defect which can be repaired by titanium plate and Teflon patch because it had the advantages of easy operation, satisfactory remodel ing, and less compl ication.
Objective To compare the clinical effects of treating prolapse of the cervical intervertebral disc by the Solis cage fusion, the titanium cage fusion or the autogenous iliac crest graft combined with the titanium plate fixation. Methods Sixty-four patients with prolapse of the cervical intervertebral discadmitted to hospital from February 2002 to May 2005 were retrospectively analyzed. In Group A, 20 patients (15 males and 5 females, aged 38.76 years, 30 intervertebral spaces) were treated with the Solis cage fusion, and the preoperative JOAscores were 9-16, averaged 11.4; in Group B, 21 patients (15 males and 6 females,aged 37-78 years, 23 intervertebral spaces) were treated with the titanium cagefusion, and the preoperative JOA scores were 8-13, averaged 10.1; in Group C, 23 patients (18 males and 5 females, aged 32-76 years, 28 intervertebral spaces)were treated with the autogenous iliac crest graft combined with the titanium plate fixation, and the preoperative JOA scores were 9-14, averaged 10.6. The comparative analysis was made among the 3 groups in the following aspects: X-ray exposure time, time working on the iliac bone, operation time, hemorrhage amount，complication incidence after operation, cervical vertebral fusion rate, symptom relief rate, and recovery rate of the JOA score. Results According to the follow-upfor 2-15 months averaged 12 months, the time working on the iliac bone was longer in Group C than in Groups A and B (11.5±2.4 vs 4.1±1.7 minand 4.2±1.9 min, P＜0.05); the operation time was longer in Group C than in Groups A and B (98.3±14.7 min vs 55.5±10.3 min and 56.8±12.6 min, P＜0.05); and the X-ray exposure time was longer in Group C than in Groups A and B (7.8±1.8 min vs 4.3±1.2 min and 4.2±1.3 min, P＜0.05). Also, the hemorrhage amount in Group C was much greater than in Groups A and B (145.8±19.3 ml vs 65.8±10.2 ml and 67.2±12.3 ml,P＜0.05). The postoperative complication rate was lower in Groups A and Bthan in Group C (P＜0.05). There was a significant difference in the complication rate in the cervical region between Group A (5.0%±1.8%) and Group B (14.3%±2.6%,Plt;0.05）. The fusion rate in Groups A and B was 100% 3-4 monthsafteroperation, and there was no difference when compared with that in Group C. The recovery rates of the JOA scores in the three groups were 81.9%±3.2%，78.9%±7.3%, and 76.3%±9.4%, respectively, and there was no significant difference among the three groups. Conclusion The Solis cage fusion has a better therapeutic effect in treating prolapse of the cervical intervertebral disc than the titanium cage fusion and the autogenous iliac crest graft combined with the titanium plate fixation. The Solis cage fusion also makes the operation easier, with a more rapid recovery rate and fewer postoperative complications in the patient.
Objective To systematically review the efficacy of poly-L-lactide (PLLA) material treatment versus titanium plates treatment for mandibular fractures. Methods We searched the Cochrane Library, PubMed, Embase, Chinese Journal Full-text Database, VIP Database, and Wanfang Database to collect literatures about randomized or non-randomized controlled trials using PLLA treatment (the trial group) versus titanium plates treatment (the control group) for mandibular fractures in the last ten years (from January 2007 to March 2017). The quality evaluation and data extraction were carried out by 2 reviewers independently and analyzed by Review Manager 5.3 software. Results A total of 8 literatures including 453 patients with mandibular fractures were included in this Meta-analysis. There was no significant difference in total complications between the two groups [odds ratio (OR)=0.98, 95% confidence interval (CI) (0.55, 1.75), P=0.95], including dislocation healing [OR= 0.96, 95%CI (0.46, 2.01), P=0.90], occlusal disturbance [OR=1.53, 95%CI (0.61, 3.87), P=0.37], infection [OR=0.63, 95%CI (0.23, 1.74), P=0.37], and secondary operation [OR=0.46, 95%CI (0.17, 1.27), P=0.14]. Conclusion There is no significant difference between PLLA and titanium plate in the treatment of mandibular fractures.
