Herein is described a haemodialysis patient with bilateral carpal tunnel syndrome suffering from recurrence unilaterally after undergoing numerous surgeries of varying methods. On the left side, she received carpal tunnel release via open method in our clinic, and has not suffered from recurrence in eight years. On the right side, she received endoscopic carpal tunnel release twice in seven years, and subsequently underwent open carpal tunnel release in our clinic for recurrence. For carpal tunnel syndrome in haemodialysis patients, we recommend open surgery rather than endoscopic surgery.

Rat models with different division of nerve roots of the brachial plexus were designed to assess whether single or two nerve roots of the contralateral normal brachial plexus can be divided as donor nerves in treatment of brachial plexus root avulsion. Two hundred and fifty-two SD rats were randomly divided into 13 groups, i.e. five groups with single nerve root division, seven groups with two nerve roots division, and one group with three nerve roots division. ⋯ Results showed that in groups with single nerve root division, the experimental limb function did not show an apparent damage; in groups with non-neighbouring two nerve roots cutting, it did show a harmful repercussions on the limb at two weeks, but most of them recovered to normal at two months; in groups with neighbouring two nerve roots division and with non-neighbouring three nerve root cutting, the limb function showed a persistent damage. In conclusion, division of nerve root alone or even non- neighbouring two nerve roots of the brachial plexus did not affect the forelimb function of the rat permanently.

We present a case of very unusual injury to the right hand of a 14-year-old boy who had an accident with a powered woodsplitter. The trauma produced a unique hand injury pattern. All fingers except the thumb were split into dorsal and volar sections without any bone fractures, mimicking surgically elevated volar flaps. We achieved satisfactory hand function using simple surgical and conservative management in this unique hand injury case.
