The posterior interosseous sensory nerve innervates the dorsal capsule of the wrist, which may provide nociceptive and proprioceptive sensation. Posterior interosseous sensory neurectomy (PISN) is commonly used as a primary or adjunctive procedure to provide wrist analgesia for a variety of wrist conditions. Currently, there is little information in the literature regarding the proprioceptive role of the posterior interosseous sensory nerve and the resultant effects of PISN on wrist proprioception. The purpose of our investigation was to examine the effect of PISN on wrist proprioception. ⋯ Therapeutic IV.

The Essex-Lopresti lesion, or radioulnar longitudinal dissociation, results from an axial load to the forearm with injury to the radial head and disruption of the interosseous membrane and the distal radioulnar joint. Unfortunately, an appreciation of the true extent of injury is not always realized in the acute setting, and patients present later with persistent or new reports of forearm discomfort and wrist and elbow pain. Reconstruction of the central band of the interosseous membrane with a bone-patellar tendon-bone graft is useful in the chronic setting and is described.

Case Reports
Simultaneous radius and ulna reconstruction with folded free vascularized fibula transfer: case report.
We report 1 case of successful treatment of radius and ulna nonunion by a folded vascularized fibular graft, in which 2 parallel fibular struts remained connected by the periosteum and peroneal vessels, and another case of infected nonunion of the ulna and radius with osseous and soft tissue defects treated by a free fibular osteoseptocutaneous flap with folded fibular graft in a 1-stage procedure.

Extensor tendon injuries are common; however, relatively few studies have evaluated extensor tendon repair methods. The purpose of this study was to investigate the properties of the running-interlocking horizontal mattress repair method with regard to tendon shortening, stiffness, strength, and time needed to perform the repair, compared with the modified Bunnell method and the augmented Becker method. ⋯ The running-interlocking horizontal mattress repair is significantly stiffer and faster to perform than either the augmented Becker or the modified Bunnell repairs, and it results in less shortening than either of these methods. The running-interlocking horizontal mattress repair should be strong enough to withstand some early motion.

A case of complete dislocation of the lunate and scaphoid resulting from a fall is reported. We are unaware of any previously reported case of simultaneous dislocation with the scaphoid completely extruded from the wrist at the time of injury. The patient was treated with a proximal row carpectomy.
