Special names of intraarticular and periarticular fracture-dislocations in orthopedics and their historical origins / 中华创伤骨科杂志

Due to the historical development, most of the current domestic knowledge of medicine comes from the western countries so that some western medical terms have been still used now. There are many special names for intraarticular and periarticular fracture-dislocations in orthopedics, most of which were named directly after the medical sages who first found or characterized the fractures in detail and some of which after the injury mechanisms. However, the names are often misunderstood by domestic orthopaedists who lack the knowledge of them. This article reviews such names in order to inspire innovative thinking domestic orthopaedists by the knowledge of how the fractures were discovered.

Relationship Between Somatosensory Evoked Potential Diversification during Operation and Short Term Outcome of Ossification of Posterior Longitudinal Ligament of Cervical Spine / 中国康复理论与实践

@#Objective To explore the relationship between the somatosensory evoked potential (SEP) diversification during operation and the short term outcome of ossification of posterior longitudinal ligament (OPLL) of cervical spine. Methods 70 OPLL inpatients from February 2008 to February 2011were included in this study. All patients received anterior cervical operation. According to the diversification of the SEP during surgery, the patients were divided into 2 groups. The preoperative and postoperative JOA scores of the OPLL patients were collected. Results There were 35 patients in the SEP no change group and 30 in SEP improved group. There was no difference in the preoperative JOA scores between them (P>0.05), but was significantly different in the postoperative JOA scores (P>0.05). Conclusion There is some relationship between the SEP diversification during operation and the short term outcome of OPLL of cervical spine.

Relationship of Radiological Characteristics and Clinical Symptoms of Ossification of Posterior Longitudinal Ligament of Cervical Spine / 中国康复理论与实践

@# Objective To explore the relationship of the radiological characteristics and clinical symptoms of ossification of the posteriorlongitudinal ligament (OPLL) of cervical spine. Methods 200 OPLL patients were recruited into this study. The data of JOA scores of theOPLL patients were collected. The stenotic rate of the cervical spine canal was calculated by the sagittal plane CT. The sorts and ossificatedcervicle were also identified by the images. Results The stenotic rate of the cervical spine canal was 19.8% to 60.3% with average 42.9%,the JOA scores was 4 to 15, averaged 10. Linear regression showed the stenotic rate of the cervical spine canal was negatively correlatedwith the JOA scores (P<0.01). There were 94 cases for segmental-type, 46 for mixed-type, 23 for continuous-type and 37 for focal-type. Thethird and fourth cervical vertebrae were susceptible to ossify. Conclusion The higher the OPLL occupation ratio, the worse the clinicalOPLL symptoms. The OPLL patients following clinical symptoms with spinal cord oppression are more likely the segmental-type.
