Ultrasound-guided topographic anatomy of the medial calcaneal branches of the tibial nerve

Background: The purpose of this study was to evaluate the topographic anatomy tibial nerve and its medial calcaneal branches in relation tip malleolus posterior superior tuberosity using ultrasound examination verify preoperative usefulness surgical treatment. Materials methods: Bilateral performed on 30 volunteers location bifurcation origin were measured. Medial analysed reference amount their respective nerves origin. Results: In 77% cases, occurred below with average distance 5.9 mm 48% cases above 2.7 mm. 73% as a single branch originating from (60%). first, second third accordingly 9.3 above, 9.5 11.6 17.7 1.6 4 tuberosity. Conclusions: As present huge variability ankle area, order prevent iatrogenic injuries, or intraoperative assessment (sonosurgery) localisation should be introduced into clinic.
