The Michigan hand questionnaire (MHQ) is increasingly being used and has been adapted cross-culturally in some Western and Asian countries, but the validation process for an Asian translation of MHQ has not been well described. In this study, we translated and adapted the original MHQ cross-culturally to produce a Korean version, and then assessed the validity and reliability of the Korean version of the MHQ. ⋯ The Korean version of MHQ showed satisfactory internal consistency, test-retest reliability, and validity and demonstrated a significant correlation with the patient-based upper extremity questionnaire and clinical assessment. We found the application and evaluation of the instrument to be feasible and understandable among patients in Korea.

Scaphoid fracture nonunion remains prevalent, and it was our purpose to examine the initial care, fracture site, and patient gender and age to determine factors contributing to fracture nonunion. ⋯ The high rates of delayed presentation and incomplete evaluation and treatment suggest a strong need for better patient and doctor education on the subject of scaphoid injuries and nonunions particularly because the initial injury is, unfortunately, sometimes perceived as trivial. Nonunions do occur despite appropriate immobilization. Proximal pole fractures and fractures that show inadequate progression toward union while being treated in a cast should be considered for surgical intervention based on the high number of such cases identified in this study.

This investigation tested the null hypothesis that psychological factors have no effect on patient satisfaction in a hand and upper limb practice. ⋯ In this study, the provider's sense that the patient was disproportionately uneasy with his or her symptoms was the only significant predictor of patient satisfaction, and this accounted for a small percentage of the variance in responses to these items. Patient satisfaction is complex, and the divide between medical advice and a patient's expectations are not easily reduced to one or more disease-specific or patient-specific factors.

To improve the degree of functional return and sensibility provided by composite tissue allotransplantation, enhanced nerve regeneration is essential. Chondroitin sulfate proteoglycans are found in the extracellular matrix of nerves and inhibit regenerating axons after injury. Treatment with chondroitinase to remove chondroitin sulfate proteoglycans has been shown to improve nerve regeneration in isolated nerve graft and transection-and-repair models. This study assesses the efficacy of chondroitinase as a neurotherapeutic agent in the setting of composite tissue allotransplantation. ⋯ Intraneural injection of chondroitinase cleaved inhibitory chondroitin sulfate proteoglycans without disrupting proregenerative laminin and resulted in enhanced nerve regeneration after composite tissue allotransplantation. Studies at later time points are needed to assess whether this enhanced nerve regeneration will produce improved functional return.
