Topography of human ankle joint: focused on posterior Tibial Artery and Tibial nerve
Anatomy & cell biology, 2015Co-Authors: Deog Im Kim, Yi-suk Kim, Seung-ho HanAbstract:Most of foot pain occurs by the entrapment of the Tibial nerve and its branches. Some studies have reported the location of the Tibial nerve; however, textbooks and researches have not described the posterior Tibial Artery and the relationship between the tibal nerve and the posterior Tibial Artery in detail. The purpose of this study was to analyze the location of neurovascular structures and bifurcations of the nerve and Artery in the ankle region based on the anatomical landmarks. Ninety feet of embalmed human cadavers were examined. All measurements were evaluated based on a reference line. Neurovascular structures were classified based on the relationship between the Tibial nerve and the posterior Tibial Artery. The bifurcation of arteries and nerves were expressed by X- and Y-coordinates. Based on the reference line, 9 measurements were examined. The most common type I (55.6%), was the posterior Tibial Artery located medial to the Tibial nerve. Neurovascular structures were located less than 50% of the distance between M and C from M at the reference line. The bifurcation of the posterior Tibial Artery was 41% in X-coordinate, -38% in Y-coordinate, and that of the Tibial nerve was 48%, and -10%, respectively. Thirteen measurements and classification showed statistically significant differences between both sexes (P

Thirteen measurements and classification showed statistically significant differences between both sexes (P<0.05). It is determined the average position of neurovascular structures in the human ankle region and recorded the differences between the sexes and amongst the populations. These results would be helpful for the diagnosis and treatment of foot pain.

Comparison between posterior Tibial Artery perforator flaps and sural flaps for reconstruction of foot, ankle and distal lower leg.
Hainan Medical Journal, 2013Co-Authors: Wang He-jAbstract:Objective To compare cosmetic and functional outcome following transfer of posterior Tibial Artery perforator flaps and sural flaps for reconstruction of foot, ankle and distal lower leg. Methods Fifty-two patients with skin defects of the foot, ankle and distal lower leg from August 2009 to February 2012 were enrolled in this study, of which 25 were treated with posterior Tibial Artery perforator flaps and 27 with sural flaps. The incidence of postoperative complications were observed, and the leg function of patients was evaluated 6 months after treatment using modified Weber scale. Results Minor flap necrosis (10%) was observed in 8.7% of the posterior Tibial Artery perforator flaps and 12.0% of the sural flaps, and partial necrosis (≥10%) was observed in 8.7% of the posterior Tibial Artery perforator flaps and 4.0% of the sural flaps. Total flap loss only occurred in 2 patients following transfer of sural flaps. Although the mean total score of the modified Weber scale of the posterior Tibial Artery perforator flaps was lower, but the difference was only significant in the Swelling subscale. Conclusion The incidence of flap necrosis and the morbidity in the donor of the posterior Tibial Artery perforator flaps was not greater than sural flap, but the former has a better aesthetic. The posterior Tibial Artery perforator flap should be recommended for reconstruction of small-to medium-sized defects at the foot, ankle and distal lower leg.

Tibial Artery Autografts: Alternative Conduits for High Flow Cerebral Revascularizations
World Neurosurgery, 2013Co-Authors: Dinesh Ramanathan, Benjamin W. Starnes, Thomas S. Hatsukami, Salvatore Di Maio, Laligam N. SekharAbstract:Background Extracranial-to-intracranial (EC-IC) bypass is a valuable tool in treating intracranial diseases requiring flow replacement or parent vessel sacrifice. Radial Artery grafts (RAGs) and saphenous vein grafts (SVGs) have been used as conduits to provide adequate high flow revascularizations. It is a therapeutic challenge when these grafts are unavailable. Methods All EC-IC high flow cerebral revascularizations performed using conduits other than RAGs or SVGs were identified from a prospective cerebrovascular registry. These patients were retrospectively reviewed for surgical technique, graft patency, graft flow, and clinical outcomes. Results Three patients (all women) underwent EC-IC bypass surgery using Tibial Artery grafts (two anterior Tibial Artery and one posterior Tibial Artery) because of the nonavailability of RAG or SVG. The two anterior Tibial Artery graft bypasses were patent with good flow at 8 and 3 months. The posterior Tibial Artery graft occluded intraoperatively. None of the patients developed vascular complications in the lower extremity due to Tibial Artery harvest. Conclusions Tibial arteries are safe, contingent alternatives to conventional conduits for performing high flow cerebral revascularizations and conduit reconstructions.
