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.

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.

We conducted an anatomic study to provide detailed information on the pectoral nerves and anatomic data on the transfer of the pectoral nerves to the axillary nerve. Moreover, we experimentally determined the feasibility of transferring the pectoral nerves to the suprascapular nerve in upper brachial plexus injury. ⋯ With an adequate length, diameter, and nerve composition, the middle and inferior branches of the pectoral nerves are suitable donor nerves to the axillary nerve and a potential source of reinnervation of the suprascapular nerve in upper brachial plexus injury.

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.

An increase in the incidence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections has been observed. The purpose of this study is to determine the change in proportion of surgically treated CA-MRSA hand infections over the last decade and to identify associated risk factors. ⋯ The proportion of surgically treated hand infections due to CA-MRSA has increased during the last decade. Intravenous drug use was the only independent risk factor for CA-MRSA infections treated in the operating room at our institution.
