A modified Matti-Russe technique of grafting scaphoid non-unions.

Introduction: In treatment of scaphoid non-union bone healing requires beside vital tissue and stability, enduring compression and a good interface between the graft and scaphoid fragments. While fixation techniques show a good primary stability, they reduce sintering and thus compression of fragments in the long term. Therefore, a modified technique optimising the cancellous interface between graft and scaphoid but still providing enough stability without fixating implants should be evaluated.

Reliability of the grip strength coefficient of variation for detecting sincerity in normal and blocked median nerve in healthy adults.

In the assessment of hand and upper limb function, detecting sincerity of effort (SOE) for grip strength is of major importance to identifying feigned loss of strength. Measuring maximal grip strength with a dynamometer is very common, often combined with calculating the coefficient of variation (CV), a measure of the variation over the three grip strength trials. Little data is available about the relevance of these measurements in patients with median nerve impairment due to the heterogeneity of patient groups.
