Research progress on the application of lower limb alignment in discoid meniscus injury / 中国骨伤

Discoid meniscus injury is a kind of common sports injury. Its treatment methods include arthroscopic discoid meniscus plasty, discoid meniscus subtotal resection, discoid meniscus total resection and so on. Although the short-term clinical effect is good, the long-term clinical effect is not ideal. At present, different scholars have different views on the choice of surgical methods for discoid meniscus injury. In recent years, many scholars have shown that the choice of operation and the change of lower limb force line are related to the therapeutic effect of discoid meniscus injury. This paper mainly summarizes the current situation of the treatment of discoid meniscus injury and the changes of the force line of the lower limbs after operation, and expounds therole of the evaluation of the force line of the lower limbs in the treatment of discoid meniscus, so as to provide the basis for the clinical individualized treatment of discoid meniscus injury.

The risk factors of periprosthetic fracture after hip arthroplasty:a meta-analysis / 中国骨伤

OBJECTIVE@#To explore risk factors of the periprosthetic fracture after hip arthroplasty.@*METHODS@#Potential studies were searched in databases including Pubmed, Embase, Cochrane Library, CNKI as well as Wanfang Database up to November 2018 and references in related literatures. The methodological quality of literature was estimated by Newcastle-Ottawa Scale. Raw data were merged and tested mainly by Revmain 5.3.@*RESULTS@#Seventeen studies in total were appropriate with 90 632 patients. The results revealed that it increased the risk of periprosthetic fracture after hip arthroplasty, including female (=1.62, 95%CI:1.44 to 1.82, =3.@*CONCLUSIONS@#Orthopedics doctors should constantly be cantious about the risk factors including female, revision and diagnosis of rheumatoid arthritis. They are supposed to prevent the periprosthetic fracture by gentle operation during hip arthroplasty and monitoring the functional exercise after operations when the above risk factors occur.

Application of fibreoptic endoscope in evaluation of swallowing / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the effect of fibreoptic endoscopic evaluation of swallowing (FEES) in the assessment of dysphagia.</p><p><b>METHODS</b>Fifty-two patients with neurogenic dysphagia underwent FEES and videofluoroscopy (VF) within a 2-day period. The results obtained were compared.</p><p><b>RESULTS</b>FEES with all consistencies revealed premature leakage in 48.1%, pooling in 75.0%, penetration in 69.2%, and aspiration in 55.8%, silent aspiration in 28.8% of patients. VF revealed above items in 44.2%, 63.5%, 57.7%, 46.2%, 21.2%, respectively. The FEES was then measured against the VF for sensitivity, specificity, positive predictive value, and negative predictive value. FEES showed higher sensibility and negative coincidence rate of penetration (90.0%, 81.3%), aspiration (87.5%, 87.0%) and silent aspiration (90.9%, 97.3%). According to the severity, the dysphagia in patients was classified into no penetration, penetration, aspiration and silent aspiration. A weighted Kappa value of 0.713 signified "substantial" agreement between the two tests.</p><p><b>CONCLUSIONS</b>FEES is an effective and valuable tool for evaluating oropharyngeal dysphagia, and is helpful in guiding the patients for diet and rehabilitation.</p>
