Evaluation of Some Morphological and Morphometric Properties of Talus

Abstract

Objective: The talus is the most proximal of the tarsal bones that establish the connection between the leg and foot, supporting the body weight and allowing it to be distributed distally. In this study, it is aimed to reveal the morphometric measurements of talus. Methods: A total of 87 dry talus (51 left, 36 right) were examined. We have classified the tali according to their facets. In addition 16 parameters were measured including, anterior-posterior length (APL), transverse width (TW), sulcus tali length (STL), sulcus tali width (STW), sulcus tali depth (STD), trochlea length (TTL), trochlea width (TTW), medial articular facet width (MAFW), medial articular facet height (MAFH), lateral articular facet width (LAFW), lateral articular facet height (LAFH), sulcus for flexor hallucis longus muscle width (FHW), sulcus depth (FHD), talar head height (THH), talar head width (THW) and talus height (TH). Results: Most of the tali were in type B2 (75.9%). We have measured APL 54.46±4.81 mm, TW 40.54±3.35 mm, STL 19.44±2.58 mm, STW 5.98±1.20 mm, STD 5.96±1.55 mm, TTL 32.91±3.01 mm, TTW 28.25±3.11 mm, MAFW 29.62±3.37 mm, MAFH 13.53±1.64 mm, LAFW 27.61±3.35 mm, LAFH 25.70±2.57 mm, FHW 7.26±1.66 mm, FHD 3.35±1.00 mm, THH 26.22±3.10 mm, THW 24.96±3.47 mm and TH 30.70±3.14 mm. Conclusion: Knowing the normal anatomy of the talus is important in preventing possible complications during surgical interventions applied to this area.
