Anatomical evaluation of the tibial nerve within the popliteal fossa

Abstract

The study has contributed to evaluate the tibial nerve and its vasculature anatomically. Ten preserved cadavers (5 male, 5 female) have been used for this study. Each cadaver was injected with red latex and through incisions the tibial nerve was exposed at the level of bifurcation of sciatic nerve. The tibial nerve in 85 % cadavers was located between middle and lower thirds at upper angle of popliteal fossa; whereas, in 15 % cadavers it was present below the piriformis muscle in gluteal region. The total length of the tibial nerve was at a mean of 65.26±14.42 cm in males and 64.79±67.61 cm in females, without significantly different. Its total diameter was at a mean of 5.51±1.55 mm, with a mean of 4.11±0.88 mm at the popliteal fossa and a mean of 3.24±0.81mm at its termination deep to the flexor retinaculum in male cadavers. In female; the means were 5.11±0.21 mm, 3.97±1.78 mm and 3.14 ± 0.03 mm respectively without significance difference. It was concluded that tibial nerve has sufficient and good blood supply. Moreover, it can be utilized as allogeneic vascularized nerve graft to repair sizable nerves after limb salvage.

Tears of the Popliteomeniscal Fascicles of the Lateral Meniscus: An Arthroscopic Classification

“…Even the all-inside sutures have to be careful as well. 25-29 Snyder et al 5 reported the applications of hook all-inside mattress suture which was operated in the joint completely, without influences to the popliteal tendon and the popliteal hiatus, and injuring the common peroneal nerve. In this study, we also used the arthroscopic all-inside repair using a suture hook for the PFLM tears, and this suture technique has achieved good clinical effect in all 36 patients.…”

The Effective Injection Point of the Popliteal Region: A Cadaver Dissection Without Removing the Perineurium

“…For blocking pain effectively, injections within the common connective tissue sheath have a higher success rate than injections outside the sheath (Lopez et al, 2014). Therefore, when considering nerve block, it is important for clinicians and researchers to understand the anatomical locations of the nerves (Driban et al, 2007).…”
