The whole leg radiograph (WLR), the standard technique for determining axial alignment, is usually taken in a standing position, although some prefer the supine position. To determine the difference between these two positions, we performed a standing and a supine WLR in 20 patients with a varus alignment. We found an average of 2 degrees more varus deviation in the standing position than in the supine position. 相似文献

Objectives
To determine the differences in the morphology of foot soft tissues between runners using different types of running shoes.Design
Cross-sectional study.Methods
Thirty-eight recreational runners were divided into four groups based on running shoe type, namely, neutral shoes, motion control shoes, minimalistic shoes and neutral shoes with custom-made insoles. An arch height index and a relative arch deformation index were calculated for each participant. An ultrasound device was used to measure the cross-sectional area and/or the thickness of selected intrinsic foot muscles (abductor hallucis, flexor hallucis brevis and flexor digitorum brevis) and extrinsic foot muscles (flexor digitorum longus, tibialis anterior and the peroneus muscles), and the thickness of the plantar fascia, Achilles tendon and heel pad.Results
Recreational runners using minimalistic shoes demonstrated stiffer foot arches than those using neutral shoes. Among the selected foot muscles, only abductor hallucis showed a significant morphological difference between shoe groups. Runners using minimalistic shoes had the thickest abductor hallucis. The minimalistic shoe runners also showed a thinner proximal plantar fascia and a thicker Achilles tendon than other runners. Insole runners had a thinner heel pad than neutral shoe runners.Conclusions
This study suggests that the morphology of foot soft tissues is associated with running shoe type in recreational runners. A sudden change in running shoe type without adjusting training volume should be undertaken with caution, since it may take time for foot soft tissues to adapt to a new shoe condition. 相似文献6.

Objective
To determine whether a prediction model combining self-reported symptoms, sociodemographic and clinical parameters could serve as a reliable first screening method in a step-by-step diagnostic approach to sleep apnea syndrome (SAS) in stroke rehabilitation.Design
Retrospective study.Setting
Rehabilitation center.Participants
Consecutive sample of patients with stroke (N=620) admitted between May 2007 and July 2012. Of these, 533 patients underwent SAS screening. In total, 438 patients met the inclusion and exclusion criteria.Interventions
Not applicable.Main Outcome Measures
We administered an SAS questionnaire consisting of self-reported symptoms and sociodemographic and clinical parameters. We performed nocturnal oximetry to determine the oxygen desaturation index (ODI). We classified patients with an ODI ≥15 as having a high likelihood of SAS. We built a prediction model using backward multivariate logistic regression and evaluated diagnostic accuracy using receiver operating characteristic analysis. We calculated sensitivity, specificity, and predictive values for different probability cutoffs.Results
Thirty-one percent of patients had a high likelihood of SAS. The prediction model consisted of the following variables: sex, age, body mass index, and self-reported apneas and falling asleep during daytime. The diagnostic accuracy was .76. Using a low probability cutoff (0.1), the model was very sensitive (95%) but not specific (21%). At a high cutoff (0.6), the specificity increased to 97%, but the sensitivity dropped to 24%. A cutoff of 0.3 yielded almost equal sensitivity and specificity of 72% and 69%, respectively. Depending on the cutoff, positive predictive values ranged from 35% to 75%.Conclusions
The prediction model shows acceptable diagnostic accuracy for a high likelihood of SAS. Therefore, we conclude that the prediction model can serve as a reasonable first screening method in a stepped diagnostic approach to SAS in stroke rehabilitation. 相似文献7.

Intramedullary nailing of proximal tibial fractures can be difficult when using the standard entry portal. We evaluated the suprapatellar portal, using a midline quadriceps tendon incision, to perform intramedullary nailing of the tibia. Seven patients were treated with this adaptation of the standard intramedullary nailing procedure. An arthroscopy was done before and after the nailing procedure. No special equipment was used to perform the intramedullary nailing. We evaluated the handling and necessary modifications of the standard intramedullary technique to introduce the locked tibial nail through the suprapatellar approach. We found this technique not necessarily more difficult than the standard intramedullary nailing of the tibia through the infrapatellar entry portal. Although the patients did not complain of patellofemoral discomfort after the suprapatellar nailing, definitive scuffing of the cartilage in the lower part of the femoral trochlea was visible. Introduction of a locked tibial nail via the suprapatellar approach was found to be possible and even advantageous for some complex upper tibial shaft fractures in compromised limbs. Some possible downsides of this approach need to be taken into account but, in some cases, they can be outweighed by the benefits. 相似文献
