The translaminar approach to canalicular and cranio-dorsolateral lumbar disc herniations.
The interlaminar approach is the standard procedure for most disc herniations in lumbar spine surgery. However, in cranially extruded disc herniations including canalicular herniations, partial or complete facetectomy is necessary with increased risk of postoperative spinal instability. We present the translaminar technique which allows a more direct and less destructive operative approach. ⋯ The translaminar approach is an effective and minimally invasive technique in both canalicular and cranio-dorsolateral disc herniations. It gives an additional possibility to avoid partial removal of the facet joints, can be performed in all lumbar segments and preserves structures important for segmental spinal stability. The approach allows access to the extruded disc fragment and intervertebral disc space comparable to classical approaches and is a frequently used operative technique in our department.

Restoration of upper arm function in traction injuries to the brachial plexus.
Restoration of upper arm function presents the main priority in nerve repair of brachial plexus traction injuries. The results are predominantly influenced by the level and extent of injury, and the type of surgical procedure. The purpose of this study is to evaluate influence of these factors on final outcome. ⋯ Regarding upper arm function the prognosis of surgically treated patients with traction injuries to the brachial plexus is generally similar in cases with central or peripheral level of injury. However, nerve transfers of collateral branches seem to be superior to nerve grafting and may be another possibility for repair in cases with extensive nerve gaps.
