The perionychium includes the nail and surrounding structures. The anatomy and physiology of the perionychium is presented in detail. Microscopic examination reveals the nail production to take place on the dorsal roof of the nail fold, the ventral floor of the nail fold, and on the nailbed to the free margin of the nail. The arterial supply is by two(More)
A 38-year-old female nurse was seen initially with several years' history of recurring intermittent ulnar wrist pain and paresthesias. The pain was aggravated by specific tasks using her hands, such as typing. Splinting and two steroid injections into the area gave only temporary relief. Surgical exploration revealed a segment of the ulnar nerve composing(More)
Diagnosis of upper extremity injuries depends on knowledge of basic anatomy and biomechanics of the hand and wrist. The wrist is composed of two rows of carpal bones. Flexor and extensor tendons cross the wrist to allow function of the hand and digits. The ulnar, median, and radial nerves provide innervation of the hand and wrist. A systematic primary and(More)
The theoretical applications and advantages of the scanning microscope in peripheral nerve research are presented. The internal anatomy of the peripheral nerve can be distinctly examined, and long segments of axons can be examined without the necessity of tedious study of multiple sections. The SEM should make it possible to more readily study the migration(More)
North American Caucasian male subjects (n = 59) and female subjects (n = 72) were surveyed, to investigate earlobe height preferences that could serve as guidelines for aesthetic earlobe surgical procedures and reconstructions. Subjects were asked to rank their preferences for variously shaped earlobes in life-size-scaled sketched male and female profiles.(More)
Rabbit common peroneal nerves will regenerate across a 1-cm gap inside polyglycolic acid tubing. Regenerated nerves are separated histologically into "minifascicles," which persist in distal segments. The conduction velocities and evoked action potential amplitudes following this type of regeneration are inferior to those seen in nerves repaired directly or(More)

Sural nerve grafts were used in three patients to bridge gaps measuring 2 1/2 to 4 1/2 cm in previously transected but not repaired posterior interosseous nerves. The grafts were done at 4, 5, and 7 months after injury. Extension was weaker in all three than on the uninjured side, but the range of motion was complete, with the exception of a slight lag of(More)
