Clinical application of special fluoroscopy method in the treatment of distal radius fractures with volar locking plate / 中国骨伤

OBJECTIVE@#The relationship between the distal screws and the wrist articular surface was assessed by the additional lateral oblique fluoroscopic view during the operation, and the dorsal tangential view of the wrist was used to observe whether the distal screw penetrated the dorsal cortex, so as to evaluate the clinical efficacy of the volar locking plate in the treatment of distal radius fractures.@*METHODS@#From January 2020 to June 2021, 45 cases of fresh distal radius fractures were treated using the volar Henry's approach, including 20 males and 25 females, aged from 32 to 75 years old with an average of (52.4±8.1) years old. During the operation, they were divided into 2 groups according to the different intraoperative fluoroscopic views:the control group of 20 cases, treated with standard anteroposterior and lateral fluoroscopic view;25 cases in the observation group, additional lateral oblique fluoroscopic view and dorsal tangential view of the wrist were taken. The wrist joint function score and postoperative complications were evaluated at 6 weeks, 3 and 6 months after operation between two groups.@*RESULTS@#All 45 patients were followed up and the duration ranged from 6 to 14 months, with an average of (10.8±1.7) months, all patients achieved bone union and the incision healed well. The incidence of postoperative complications in the observation group was lower than that in the control group, and the difference was statistically significant (P<0.05). In terms of Gartland-Werley score of wrist joint function, the score of wrist function in the observation group was (4.58±1.31) at 6 weeks, (2.98±0.63) at 3 months and (1.95±0.65) at 6 months post-operatively, which were better than those in the control group (6.32±1.96) at 6 weeks, (3.63±0.76) at 3 months and (2.43±0.73) at 6 months. The difference was statistically significant (P<0.05). In the observation group, 7/25 cases(28%) were found to have screw penetration during the operation by additional lateral oblique and dorsal tangential radiograph fluoroscopic views of wrist.@*CONCLUSION@#The addition of lateral oblique and dorsal tangential during the operation could improve the accuracy of distal screw placement, reduce postoperative complications, and achieve early functional exercise.

Experimental study on effect of body position on lung ventilation determined by electrical impedance tomography / 医疗卫生装备

Objective To monitor and compare the effects of body position on the regional lung volume and FEV1/FVC with electrical impedance tomography(EIT).Methods Twelve healthy young subjects[(26.6±2.5)yr]were detected by EIT during FVC maneuver in 3 body positions (sitting,supine and prone).Functional EIT images of FVC and FEV1/FVC were obtained;the proportion of regional ventilation volume and the mean of regional FEV1/FVC were calculated.Results The ventral and dorsal proportion of ventilation volume was 37.65% : 62.35% in sitting position and 37.59% : 62.41% in supine position, respectively.While in the prone position,the value was 48.56%:51.44%,which was close to 1:1.The mean of regional FEV1/FVC in the dependent lung region was 0.84 in supine position and 0.81 in prone position,while in sitting position,the corresponding value was 0.90 and 0.94, respectively. Conclusion The results shows that the ventilation transfers to the gravity dependent region obviously, while the flow rate decreases. The result provides direct evidences for mechanical ventilation patients using prone position to improve oxygenation,as well as a research foundation for EIT monitoring regional lung ventilation in the clinical setting.

Effect of Galvanoiontophoresis Combined with Ultrashort Wave Therapy on Cervical Vertebrae Disease-derived Arrhythmia / 中国康复理论与实践

@#ObjectiveTo observe the curative effect of galvanoiontophoresis combined with ultrashort wave therapy on cervical vertebrae disease-derived arrhythmia.Methods112 patients with cervical vertebrae disease-derived arrhythmia were randomly divided into the treatment group and control group with 56 cases in each group. All patients of two groups were treated with antiarrhythmia drug, Sibelium and traditional Chinese medicine. While, the patients of the treatment group were added with galvanoiontophoresis combined with ultrashort wave therapy to eliminate the aseptic inflammation.ResultsThe cure rate and total effective rate of the treatment group were 51.8% and 94.6%. Those of the control group were 16.1% and 76.8%. The effect of the treatment group was better than that of the control group significantly ( P<0.01).ConclusionThe galvanoiontophoresis combined with ultrashort wave therapy has a better effect on cervical vertebrae disease-derived arrhythmia.
