ABSTRACT

Background: The posterior interosseous nerve (PIN) is considered an ideal nerve for nerve grafting to bridge digital nerve lesions as it has minimal morbidity due to sensory loss. This study was conducted to identify the length of the nerve available for grafting by measuring the PIN from its last muscular branch to the pseudoganglion and to the Lister’s tubercle.

Materials and Methods: The length of the PIN was measured from its last muscular branch using Vernier’s callipers in previously dissected upper limbs which were used for routine MBBS dissection teaching.

Results: The mean length of PIN available for grafting was 4.71 cm to the pseudoganglion and was found 6.13 cm above the Lister’s tubercle.

Discussion: Since the PIN as a nerve graft shows less deficits post operatively, it is considered an ideal candidate for nerve grafting. In our study, we have found that the available length of grafting is about 4cm which is ideal for replacing digital nerves.

Conclusion: This study shows that a nerve length of 3-5 cm could be available for nerve grafting while using the PIN. The nerve can be usually located 5-7 cm above the Lister’s tubercle. Hence, it is easily located and a good candidate for replacing digital nerves in the hand.

Key words: Posterior Interosseous nerve, Nerve Graft, Lister’s tubercle, Radial nerve.
