Perilunate dislocations and transscaphoid perilunate fracture dislocations are associated with a high incidence of posttraumatic arthritis. According to the current literature, at medium-term follow-up, radiological signs of arthritis do not correlate with functional scores. The aim of this study was to evaluate patient hand function and the development of posttraumatic arthritis after perilunate dislocations (11 cases) and transscaphoid perilunate fracture dislocations (7 cases) at a minimum 10 years of follow-up. ⋯ Therapeutic IV.

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.

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.

Peripheral compression neuropathies are familiar to the hand surgeon. Although compression neuropathies of the forearm are far less common than those of the wrist (namely, carpal tunnel syndrome), for the patient suffering from one of these neuropathies, a missed diagnosis has far-reaching consequences. In this 2-part review (I: Radial Nerve; II: Median Nerve), several compression neuropathies of the forearm are examined. We will first discuss compression neuropathies affecting the radial nerve: (1) posterior interosseous nerve syndrome, (2) radial tunnel syndrome, and (3) superficial radial nerve compression (Wartenberg's syndrome).
