Delayed Spinal Cord-Brachial Plexus Reconnection after C7 Ventral Root Avulsion: The Effect of Reinnervating Motoneurons Rescued by Riluzole Treatment.

Ventral root avulsion induces dramatic loss of the affected spinal cord motoneurons. The neuroprotective effect of riluzole has been previously proven on the injured motoneurons: the vast majority of them can be rescued even when they have no possibility to regenerate their axons. In this study the number of injured motoneurons rescued by riluzole treatment and their capacity to reinnervate the denervated forelimb muscles was investigated.

Short-term results of total hip replacement due to acetabular fractures.

Objectives: This study aims to evaluate short-term results of total hip replacement performed for post-traumatic osteoarthritis and/or femoral head necrosis caused by acetabular fractures.

Patients And Methods: We performed 39 arthroplasties due to acetabular fractures on 25 male and 14 female patients during the course of a five-year period. The mean age of the patients was 45 years (range 25 to 73 years) at the time of surgery.

Increased survival and reinnervation of cervical motoneurons by riluzole after avulsion of the C7 ventral root.

Although adult motoneurons do not die if their axons are injured at some distance from the cell body, they are unable to survive injury caused by ventral root avulsion. Some of the injured motoneurons can be rescued if the ventral root is re-inserted into the spinal cord. Brachial plexus injuries that involve the complete or partial avulsion of one or more cervical ventral roots can be treated successfully only if satisfactory numbers of motoneurons remain alive following such an injury at the time of reconstructive surgery.

Changing the treatment to reduce complication rate in open tibial fractures.

Complications of open tibial fractures have been found to be very frequent after application of monotherapies (external fixator, plate, intramedullary nailing). The use of combined therapy has improved our results. We treated 658 patients for open tibial fractures over a course of 15 years.
