Prospective screening for PNP revealed an incidence in children younger than 1 year of 6%. Early plication substantially reduces the duration of ventilation, with its associated reduced morbidity and ICU stay.
Stump length is an important factor in attaining successful prosthetic rehabilitation in below- knee (BK) amputees. Stability of the stump- prosthesis complex is impaired in the case of a stump shorter than 10 cm. Thus, fitting a prosthesis to a BK amputee with a stump which is very short often requires the use of different prosthetic techniques. In this work, the authors suggest the use of a Swedish knee-cage attached to a conventionai patellar-tendon-bearing prosthesis as an alternative solution in the case of a short BK stump. Objective evaluation was performed by an analysis of gait and the foot- ground reaction forces. The results obtained indicate an improvement in all the measured parameters resulting from the modified stump- prosthesis complex.
Genu recurvatum is a consequence of a poor control over the knee joint due to muscle weakness, impaired tonus and deficit in joint proprioception. Uncontrolled locking of the knee during ambulation causes recurrent microtrauma which leads to degenerative changes and instability. Known methods to control hyperextension of the knee during ambulation often fail. We have used the Swedish knee-cage attached to ankle-foot brace in an attempt to improve control over the knee in three patients. Gait analysis was performed to evaluate the effectiveness of this combined orthosis. Quality of gait improved, as demonstrated by a decrease in stance time asymmetry in the order of 45%; stride increased by 29% and speed of ambulation increased by 72%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
