Posterior arthroscopic approach to the ankle

摘要: Abstract Purpose: The purpose of this study is to verify the safety a new technique for posterior arthroscopic approach ankle. This was recently described in literature. uses modified posteromedial portal, different way introducing instruments into and tendon flexor hallucis longus (FHL) as landmark work compartment. Type Study: Anatomic study. Methods: performed on 10 (4 fresh 6 fresh-frozen) below-knee amputation specimens, which were then dissected. left place, anatomic dissections determine relationship surrounding neurovascular structures. Then removed, distance structures from portal recorded. Another medial 1 cm more proximal, also created measure latter nervous Results: None showed injuries bundle either during penetration or procedures compartment laterally FHL. prevent damage medially located nerves vessels. located, average, 13.3 mm (range, 11 17 mm) tibial nerve, 14.7 8 20) calcaneal branch (which may be single multiple, vary needed height bifurcation nerve), 17.3 15 21 artery. A proximally average 2.9 closer Conclusions: Based these data, there appears relatively little risk with technique. Therefore, safe treatment intra-articular extra-articular pathology.
