The Carpal Height Ratio for The Trinidadian Population: What is Normal?

Aim: To determine the normal carpal height ratio for the Trinidadian population. Design & method: A retrospective review of wrist radiographs performed during the period January 2022 to June 2022 at San Fernando General Hospital was conducted. A total of 200 radiographs were independently reviewed by two blinded assessors utilizing the PACS system. The carpal height ratio (CHR) and revised carpal height (RCH) ratio was calculated using two methods. A p-value Results: The radiographs reviewed consisted of 94 female and 106 male patients with an age range of 19 to 86 years. The mean CHR was 0.473 and the revised CHR 1.469. The ratio for carpal height as well as the revised CHR was observed to vary amongst the different age groups studied. The CHR and revised CHR for the population was observed to vary based on gender with gender significantly influencing the CHR value (p = 0.001). Conclusions: The CHR of the Trinidadian population as calculated by the data collected falls below the average CHR documented worldwide. However, the interpretation of this value is based on the baseline reference ratio for a population. Therefore, according to our average CHR for our population previous comparison of a CHR index to international figures would have led to erroneous interpretation of results. A decrease in CHR is indicative of carpal collapse. The comparison of CHR to the established normal CHR for the population is believed to allow for early detection of carpal collapse.

基于腕部可穿戴设备的跌倒监护系统设计与实现

随着社会老龄化加快,老年人或病人的人工监护成本越来越高,针对目前各种跌倒监测装置的不足,设计了一款基于腕部智能穿戴设备的生理体征采集、跌倒监测和报警系统,该装置通过集成的各种传感器采集腕部高度、加速度、角速度等体征信号,并采用合适的算法实现了跌倒检测报警功能;实验结果表明,通过佩戴文章设计的腕部智能穿戴设备可以较好地实现对跌倒行为和日常非跌倒行为的区分,在不影响佩戴者舒适度情况下行为检出率可达到98.5%。

外固定架联合中药抗骨质疏松治疗对老年不稳定型桡骨远端骨折患者桡骨远端高度及腕关节功能的影响

目的 观察外固定架联合中药抗骨质疏松治疗对老年不稳定型桡骨远端骨折患者桡骨远端高度及腕关节功能的影响。方法 回顾性分析32例采用外固定架联合中药抗骨质疏松治疗的老年不稳定型桡骨远端骨折患者的临床资料,观察患者术后桡骨远端高度及腕关节功能恢复情况。结果 患者术后3个月及术后6个月腕关节功能均优于术后8周(P<0.05)。术后各时点桡骨远端高度均大于术前(均P<0.05),而术后各时间点之间差异无统计学意义(均P>0.05)。结论 采用外固定架联合中药抗骨质疏松治疗老年不稳定型桡骨远端骨折,可恢复并长期维持患者桡骨远端高度,改善患者腕关节功能。

外固定架结合补肾壮骨中药治疗不稳定型桡骨远端骨折临床研究

目的:观察外固定架结合补肾壮骨中药治疗不稳定型桡骨远端骨折的临床疗效。方法:采用随机数字表法将60例不稳定型桡骨远端骨折患者分为治疗组、对照组各30例。对照组采用切开复位钢板内固定治疗,治疗组采用外固定架结合补肾壮骨类中药治疗。比较2组临床疗效、手术时间、骨折愈合时间;比较2组治疗前后桡骨远端高度、中医证候评分。结果:治疗组优良率为90.00%,高于对照组83.33%(P<0.05)。2组治疗1 d、4周、8周、3个月后桡骨远端高度均高于治疗前(P<0.05),治疗组治疗8周、3个月后桡骨远端高度高于对照组(P<0.05)。2组治疗后中医证候评分均低于治疗前(P<0.05),且治疗组治疗后中医证候评分低于对照组(P<0.05)。治疗组手术时间、骨折愈合时间均较对照组缩短(P<0.05)。结论:外固定架结合补肾壮骨类中药治疗不稳定型桡骨远端骨折疗效确切,能够改善患者的腕关节功能,缩短骨折愈合时间。

半环式外固定架治疗C型桡骨远端骨折21例

目的:采用半环式外固定架治疗C型桡骨远端骨折,观察对桡骨短缩移位的干预,评估其临床疗效。方法:回顾性纳入2016年1月至2019年10月C型桡骨远端骨折患者21例。研究在术前、术后当日、术后3周、6周及半年共5个时间点受试桡骨高度指标情况,进行重复测量资料的方差分析。研究术前、术后6周及半年共3个时间点评估受试Garland-Werley(GW)指标情况,进行重复测量资料的方差分析。结果:桡骨高度方面,术后当日、术后3周及6周时,桡骨高度变化差异无统计学意义(P>0.05)。半年后(即拆除外固定架后)出现高度降低,差异有统计学意义。GW指标在术后半年时明显优于术后6周,差异有统计学意义(P<0.05)。结论:半环式外固定架治疗C型桡骨远端骨折,可发挥其优势,维持桡骨高度并恢复腕关节功能,但固定架拆除后仍会有部分桡骨高度降低。
