The therapeutic efficacy of minimally invasive modified transforaminal lumbar interbody fusion combined with unilateral nail holding system in patients with extreme lateral lumbar disc herniation / 中国医师进修杂志

Objective To investigate the therapeutic efficacy of minimally invasive modified transforaminal lumbar interbody fusion (TLIF) combined with unilateral nail holding system in patients with extreme lateral lumbar disc herniation.Methods Thirty-eight patients with extreme lateral lumbar disc herniation were divided into minimally invasive modified TLIF combined with unilateral nail holding system group (observation group) and conventional open TLIF group (control group) with 19 cases each according to random digital table method.The therapeutic efficacy was compared between 2 groups.Results Surgery was completed successfully in 2 groups,and there was no perioperative complications.The amount of bleeding and hospital stay length in observation group were significantly less than those in control group:(152 ± 82) ml vs.(258 ± 104) ml and (6.5 ± 2.3) d vs.(12.7 ± 3.6) d,and the rate of fusion and score of Japan Orthopaedic Association 6 months after surgery in observation group were significantly higher than those in control group:18/19 vs.10/19 and (14.5 ± 2.1) scores vs.(12.6 ± 1.9) scores.There were statistical differences (P ＜ 0.01).There was no statistical difference in complications between 2 groups (P ＞ 0.05).Conclusion Minimally invasive modified TLIF combined with unilateral nail holding system in patients with extreme lateral lumbar disc herniation has less blood loss and shorter hospital stay,and it is effective and safe.

Improving orthopedics clinical teaching quality by combining anatomy and image knowledge / 中华医学教育探索杂志

Students generally felt difficult in studying during clinical practice and the orthopedics teaching quality was unsatisfactory due to the discrepancies existed among teaching of anatomy,imagie and orthopedics clinical practice concerning the time,content,requirement and method.Students' understandings of anatomy and image knowledge were improved through launching theoretical study by means of lectures and case discussion.Students' understandings of orthopedics diseases were promoted through preoperative diagnosis and intraoperative conformation using anatomy and image knowledge for the patients they were responsible for.In all,orthopedics clinical teaching quality was promoted through applying these measures.
