Tinel sign is used for depecting ?
Tinel&;s sign is an impoant sign ,which helps in recording the rate of regeneration of nerve clinically . Procedure: gentle percussion is done along the course of injured nerve . Tingling sensation is experienced by the patient in the distribution of injured nerve rather than the area percussed , & the sensation should persist for several seconds following the stimulation .Positive tinel&;s sign indicate regenerating axonal sprouts have not obtained myelinization .Response fades as myelinization take place . Distal progression of response & rate of progression have been used by some to establish the prognosis ( rate of recovery should be 3cm / month) Presence of this sign is encouraging . Even a few regenerating sensory fibres can result in positive tinel&;s sign . REF:textbook of ohopedics, John ebenezer,4th edition, pg .no. 333
