Objective To study the injuries of avulsion and severance of upper extremity caused by flexion and rotation and application of tissues of chest side and back in functional reconstruction of the upper extremity. Methods The primary or fosterage replantations were performed from 2000 July to 2003 September for 6 cases of the injuries of avulsion and severance of upper extremity caused by flexion and rotation. After the operation, the shoulder joint was immobilized at abduction of 90 degrees and elbow joint was fixated at inflexion of 100 degrees. 4 weeks later, the fixation was removed and the regular functional training was started. Results Follow-ups ranging from 3 months to 2 years revealed that all the cases of replantation were successful. After operation, the shoulder joint could abduct 50?~90?, anteflect 50?~70?, extend backwards 20?~30?, and adduct 20?~40?. The elbow joint could flex 100?~140?and extend -20?~0?. 3 months after reconstruction, the muscle strength of elbow flexion recovered to Ⅳ~Ⅴdegrees. Conclusion Application of tissues of chest side and back to repair avulsion and severance of upper extremity stage by stages and layer by layer is an ideal method to resolve the contradiction between wound coverage and functional reconstruction because it can restore both the function and appearance.

OBJECTIVE:
To investigate the clinical characteristics and common etiology of vertigo.
METHOD:
The clinical data of 168 patients with vertigo in the department of otolaryngolology and neurology from December 2007 to March 2009 were retrospectively analyzed The patients were inquired and examined by pure tone average thresholds, videonystagmography, Dix-Hallpike test, cervical spine X-ray, skull CT and (or) MRI and transcranial Doppler.
RESULT:
One hundred and thirty-four patients with vertigo were of peripheral origin, with 66 cases benign paroxysmal positional vertigo, 30 cases Meniere's disease, 24 cases sudden deafness, 5 cases vestibular neuritis, 5 cases otitis media ,2 cases ear herpes zosters and 2 cases ototoxicity. Among 26 patients with vertigo of central, 20 patients were vertebrobasilar TIA.
CONCLUSION
The most common etiology of the vestibular peripheral vertigo is the benign paroxysmal positional vertigo. Detailed history and the features of vertigo, particular about the duration of vertigo and hearing change, may provide the important evidences for the accurate diagnosis and differential diagnosis of vertigo.
