ABSTRACT
Objective To measure the anatomical morphology of coracoclavicular ligament based on fresh cadavers, and to provide anatomical basis for anatomical reconstruction of coracoclavicular ligament. Methods A total of 52 the acromioclavicular joints (fresh body specimen) was dissected, and the anatomical characteristics of coracoclavicular ligament were observed by dissecting acromioclavicular joint specimens. The anatomic data of which the length of the conoid ligament (QR), the length of the trapezoid ligament (ST) ; the distance from the conoid ligament attachment on coracoid to coracoid tip (RV), the distance from the trapezoid ligament attachment on coracoid to coracoid tip (TV), the distance form conoid ligament attachment on the clavicular to acromioclavicular joint (QU), the distance form the trapezoid ligament attachment on the clavicular to acromioclavicular joint (SU), the distance from supraclavicular plane to subcoracoid plane (WX) were measured ; and the mean diameter of the trapezoid ligament attachment on the clavicular (ā), the mean diameter of the conoid ligament attachment on the clavicular(b¯), the mean diameter of the trapezoid ligament attachment on the coracoid (c¯), the mean diameter of the conoid ligament attachment on the coracoid (d¯) were calculation. The measurement result underwent statistical analysis. Results The minimum diameter of the trapezoid ligament attachment on the clavicular and coracoid on the left and right sides, respectively. There were no significant differences in those anatomical morphology of the coracoclavicular ligament (P>0.05). The anatomical morphology of the diameter of coracoclavicular ligament attachment on the male and female had no significant difference (P>0.05). The maximum length of the conoid ligament was (14.19±2. 43/15. 87±2. 99) mm on the left and right sides, respectively. The distance from the conoid ligament attachment on coracoid to coracoid tip was ( 36. 66 ± 4. 25/33. 61 ± 3. 45 ) mm on the left and right sides, respectively. The mean diameter of the conoid ligament attachment on the clavicular and coracoid was (11.95± 1.43/ 11.23± 1.12)mm and (9.20± 1.60/7.90±0.76) mm on the left and right sides, respectively. There were significant differences in those anatomical morphology of the coracoclavicular ligament(P 0.05). The anatomical morphology of the coracoclavicular ligament on the male and female had no significant difference (P>0.05). Conclusion The comprehensive measurement of anatomical morphology of coracoclavicular ligament can provide an anatomical basis for shoulder joint diseases related to coracoclavicular ligament injury. It will help surgical staff perform a complete anatomic reconstruction of coracoclavicular ligaments for the surgical treatment of dislocation of the acromioclavicular joint.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the thinking and method of studying the diagnostic standard for TCM Syndrome Differentiation by means of clinical epidemiological investigation on climacteric syndrome.</p><p><b>METHODS</b>Adopting DME (design measurement evaluation), the field investigation data of 400 patients with climacteric syndrome were statistically managed and analyzed using blind method. The distribution of syndromes, including information of four-diagnosis of various syndromes as well as the laboratory findings in patients were studied using factor analysis and model of structural equation.</p><p><b>RESULTS</b>The Syndrome types of climacteric syndrome were identified as the Gan-Yang exuberance type, the Shen-Yang deficiency type, the Gan-Shen Yin-deficiency type and the Gan-stagnancy injuring Spirit type.</p><p><b>CONCLUSION</b>Thinking of the diagnostic standard study for TCM Syndrome Differentiation is to identify the supposed diagnostic standard of a disease based on retrospective study, to formulate a new hypothetical standard of Syndrome by way of field investigation, category analysis, factor analysis, and critical theory, followed with identification of Syndrome distribution in the disease, its critical syndrome, typical syndrome, complicated syndrome, and criteria for Syndrome Differentiation.</p>
