Is it possible to follow the risk of rupture after end-to-end nerve repairs in brachial plexus surgery? Technical...

In traumatic and obstetric brachial plexus injuries, removal of the damaged nerve, repair with the nerve grafts, and nerve transfers are mostly preferred techniques. Success is directly proportional to surgical technique as it is known that end-to-end repair of the peripheral nerves gives better results. The greatest risk in end-to-end repair is the nerve rupture at the brachial plexus repair region and this cannot be detected by conventional radiological techniques.

Brachial plexus injuries of obstetrical and traumatic patients were operated. If possible and at least one nerve was repaired end to end, follow-up of nerve continuity was done by titanium hemopclip insertion to both sides of the nerve repair area. A new technique nerve repair site marking was developed and end-to-end nerve repair continuity was followed simply by x-ray.

This technique was used for end-to-end nerve coaptions of 38 obstetric and 40 traumatic brachial plexus injuries. Follow-up was done for 6 weeks. Every week patients sent the x-ray of the repair site. Only 3 patients had nerve repair site rupture, and revision surgery was done immediately.

Nerve repair site marking technique and follow-up with only x-ray is a simple reliable, safe, and cheap method that can be applied to any end-to-end nerve repair. This technique has no morbidity or side effects. The aim of the study is to summarize or explain the nerve repair site marking technique used in the brachial plexus region.
