    Abstract:

    With the use of data from 3 Louisiana State University Health Sciences Center (LSUHSC) publications, various parameters for buttock/thigh-level sciatic nerve and tibial and common peroneal divisions/nerve injuries were summarized, and outcomes were compared.Data from 806 buttock/thigh-level sciatic nerve and tibial and common peroneal division/nerve injury repairs were summarized. Lesion types, repair techniques, and outcomes were compared.Acute lacerations undergoing suture repair were best for the thigh-then-buttock-level tibial (93%/73%) and then same-level common peroneal divisions (69%/30%); at the knee level, tibial outcomes (100%) were better than those for the common peroneal nerve (CPN) (84%). Secondary graft repairs for lacerations had good outcomes for the thigh-then-buttock-level tibial (80%/62%), followed by common peroneal divisions at the same levels (45%/24%). The knee/leg-level tibial nerve (94%) did better than the CPN (40%) here. In-continuity lesions with positive intraoperative nerve action potentials underwent neurolysis with better results for the thigh-then-buttock-level tibial division (95%/86%) than for same-level CPN (78%/69%). The knee/leg-level tibial nerve did better than the CPN (95%/93%).Better recovery of buttock- and thigh-level tibial division/nerve occurs because: 1) the CPN is lateral and thus vulnerable to a more severe injury; 2) the tibial nerve is more elastic at impact owing to its singular-fixation site (the CPN has a dual fixation); 3) the tibial nerve has a better blood supply and regeneration; 4) the tibial nerve has a higher force-absorbing fascicle/connective tissue count than the CPN; and 5) the tibial nerve-innervated gastrocnemius soleus requires less reinnervation for functional contraction than deep peroneal branches, which innervate long, thin extensor muscles at multiple sites and require coordinated nerve input for effective contraction.
