Contralateral cervical seventh nerve transfer for spastic arm paralysis via a modified prespinal route: a cadaveric study.
We proposed contralateral cervical seventh nerve transfer for spastic arm paralysis after central neurological injury in the New England Journal of Medicine (NEJM) in 2018. In this surgery, we applied a new surgical route for nerve transfer, the Huashan prespinal route. The objective of this study was to elaborate our new surgical technique, clarify its relationship to the vertebral artery, and provide anatomical data on this novel method. ⋯ The cadaveric study confirms that the presented technique allowed simple, effective, and safe contralateral C7 nerve transfer. This technique can be used in the treatment of hemiplegia and brachial plexus injury. There is a safe scope of drilling angle for creating the longus colli muscle tunnel required for this surgical route. The anatomical parameters obtained in this study will be helpful for the performance of this operation.

Comparative StudyFlow-regulated versus differential pressure valves for idiopathic normal pressure hydrocephalus: comparison of overdrainage rates and neurological outcome.
To compare flow-regulated (FR) and differential pressure (DP) valves for treatment of patients with idiopathic normal hydrocephalus (iNPH) focusing on overdrainage and neurological outcome. ⋯ The current study demonstrates a comparable neurological improvement between DP and FR valves, with potentially lower overdrainage rates among FR valves. Long-term studies will be necessary to draw a definite conclusion on FR valves for treatment of iNPH patients.
