ABSTRACT
Two famous methods are commonly used for the measurement of carpal height ratio. Both methods are performed on anteroposterior radiogram and have some shortcomings. We are going to introduce a new method for measuring this index in lateral view of the wrist radiogram. This cross-sectional and case-control study was conducted on 100 anteroposterior and lateral radiograms of asymptomatic individuals and then 20 radiograms of patients with Kienbock disease in various stages of the disease. After determining new reference points on the radiograms of the [normal] group, it was tried to define the ratio by new method. In the next stage the interobserver and intraobserver agreement of the new index was assessed along with previous defined indices. All three methods had some limitations, but overall it seems that the new method has more precise reference points. With regard to inter and intraobserver variability the new index was better than the Natrass group index, but not than the Youm group index. The new index can be used as a substitute or an alternative in carpal height measurement

The aim of this study was to determine if deprivation of tactile sense could be compensated by hearing sense, early after the nerve repair in hand. This may hypothetically help to maintain the cortical hand representation during the early denervation period. [Audiovisual tactile]; apparatus was used early after repair of the ulnar nerve in order to improve recovery of hand sensibility by maintaining an active sensory map of the hand in the somatosensory cortex during the differentiations period. This tool was used in a 25- years-old man. Then sensory evaluation was performed at regular intervals in 2, 5 and 7 months after the intervention. Sensory improvement was better in the patient who used the artificial sensibility regimen compared with the others who did not. This study suggests that the onset time of sensory afferent inflow after nerve repair is a very important agent to focus on sensory re-education
ABSTRACT
Elbow dislocation, though not a rare injury has been only occasionally reported to occur bilaterally. An extremely rare case of upper extremity trauma is reported in which bilateral simultaneous posterior elbow dislocation associated with bilateral radial neck fractures had occurred. To the best of our knowledge, this hasn't been reported previously. Although radial head excision has been reported to be associated with good outcome in cases of elbow dislocations with fracture of radial neck, the trend has been toward preservation of the head and it seems that this is a more logical approach
