Objective To investigate the discriminant validity and relativity of three scales applied in fall risk estimation for senile patients.Methods The timed up and go test (TUGT),the Morse Fall Scale (MFS) and the Berg Balance Scale (BBS) were used by two trained testers to evaluate the fall risk of 161 senile in-patients.The patients were divided into a falling group and a no-fall group based on their history of falling in the previous one year.Student's t-test was applied to compare the discriminant validity of the TUGT,MFS and BBS.Spearman's correlation coefficient was calculated to analyze the correlation among the three scales.Results The scores of patients in the falling group on the three scales were significantly different from those of the no-falls group.The correlation coefficients among the three scales were in the range 0.680-0.888.Conclusion The TUGT,MFS and BBS all showed high sensitivity and good discrimination in fall risks estimation for senile patients.The results with the three scales were highly correlated.Because the emphasis of these three scales is different,a suitable scale should be selected in clinical practice according to the characteristics of the senile patient.

Objective To investigate the clinical efficacy of internal fixation through posterior minimally invasive approach in treating unstable scapula fractures.Methods A retrospective case control study was conducted on the clinical data of 36 patients with scapular fractures admitted between May 2011 and August 2016.There were 30 males and six females,with average age of 51.5 years (range,46-64 years).According to Hardegger classification,there were 18 patients with scapular body fracture,14 with scapular neck fracture,and four with glenoidal fracture.According to operation method,the patients were divided into Group A (n =24) which adopted internal fixation through posterior minimally invasive approach and Group B (n =12) which adopted the conventional Judet approach for internal fixation.The incision length,operation time,intraoperative bleeding,fracture healing time,Hardegger standard of clinical effects,and complications in two groups were compared.Results All patients were followed up for average 18 months (range,6-24 months).The total length of surgical incision was (12.50 ± 4.50) cm in Group A and (27.95 ± 5.20) cm in Group B (P ＜ 0.05);the operation time was (86.5 ± 1 1.5) minutes in Group A and (120.6 ± 10.9) minutes in Group B (P ＜ 0.05);the intraoperative bleeding was (200.0 ± 20.0)ml in Group A and (420.0 ± 20.0)ml in Group B (P ＜ 0.05);fracture healing time was (10.0 ± 1.0) weeks in Group A (12.0 ± 1.5) weeks in Group B (P ＜ 0.05).According to Hardegger standard,in Group A,15 patients were excellent,six good,and two fair,with an excellent and good rate of 91％;while in Group B,six patients were excellent,three good,two fair,and one poor,with an excellent and good rate of 75％ (P ＜ 0.05).No complications were observed in Group A.In Group B,one patient with hematoma and one patient with nonunion of incision area were observed,both of which recovered after drainage and dressing change.One patient with superior scapular nerve injury was found and recovered after treatment.The incidence of complications was 25％ in Group B,higher than 0 in Group A (P ＜ 0.05).There was no internal fixation fracture or nonunion in two groups.Conclusion Compared with the conventional Judet approach,minimally invasive internal fixation approach in the treatment of unstable scapula fracture demonstrates the advantages of mild trauma,faster functional restoration,and fewer complications.

OBJECTIVE: To study the changes of vestibular function in patients with diabetes mellitus and its clinical significance. METHOD: Electronystagmography (ENG) was used to examine 76 patients with diabetes mellitus and 60 healthy adults subjects. After clinical detection of vestibular function including spontaneous nystagmus, positional test, head shaking nystagmus, neck torsion test, caloric test, and sensory organization tests which consist of gaze, saccade and smooth pursuit test, the results of these two groups were recorded for qualitative and quantitative statistical analysis. RESULT: The rate of vestibular dysfunction in patients with diabetes mellitus were 68.4%. and that of the controls were 8.3%. There was significant difference between these two groups (chi2 = 15.472, P < 0.01). CONCLUSION Vertigo or dizziness occurred in patients with diabetes mellitus might be related to vestibular dysfunction. ENG test could be used as one of the objective clinical examinations in patients with diabetes mellitus.
