To explore long-term recovery of elbow flexion and extension after transferring the phrenic nerve and intercostal nerves, respectively, in adults with global brachial plexus avulsion injuries. ⋯ Therapeutic IV.

Comparative Study
A comparison of intercostal and partial ulnar nerve transfers in restoring elbow flexion following upper brachial plexus injury (C5-C6+/-C7).
Restoring active elbow flexion is essential in the surgical management of C5-C6 +/- C7 brachial plexus palsies. This study compares the clinical results of 2 techniques to restore elbow flexion: the partial ulnar nerve transfer and the intercostal nerve transfer. ⋯ Therapeutic III.

Hammering is a functional task in which the wrist generally follows a path of motion from a position of combined radial deviation and extension to combined ulnar deviation and flexion, colloquially referred to as a dart thrower's motion. The purpose of this study was to measure wrist and forearm motion and scaphoid and lunate kinematics during a simulated hammering task. We hypothesized that the wrist follows an oblique path from radial extension to ulnar flexion and that there would be minimal radiocarpal motion during the hammering task. ⋯ The simulated hammering task was performed using a wrist motion that followed a coupled path of motion, from extension and radial deviation to flexion and ulnar deviation. Scaphoid and lunate rotations were greatly reduced, but not minimized, compared with rotations during pure wrist flexion/extension. This is likely because an extended wrist position was maintained throughout the entire task studied.

We describe a new pattern of upper limb injury: a combination of fractures of both radius and ulna, with a rare type of trans-scaphoid transcapitate transhamate greater arc injury of the wrist and fractures of metacarpals, managed successfully.
