Abstract: OBJECTIVE: Aim: To study the anatomy of the posterior inferior tibiof i bular ligament (PITFL) and specify the features of its morphology and linear parameters. PATIENTS AND METHODS: Materials and Methods: The peculiarities of morphology and linear parameters of PITFL on 10 fresh amputated lower limbs were studied. The average age of the patients was 64.7 ± 9.3 (7 males, 3 females). Macroscopic characteristics, insertion, orientation in relation to the corresponding bony and ligamentous anatomical structures were studied, and linear parameters of PITFL were measured using a caliper. Average values were calculated. RESULTS: Results: PITFL was detected in all the studied samples. It represented a strong, compact anatomical structure of a trapezoidal or triangular shape. The proximal width of the PITFL averaged 20 ± 3.65 mm, while the distal width was 36.6 ± 4.62 mm. The attachment length of PITFL to the posterior part of the tibia was 28.6 ± 5.13 mm and to the fi bula was 17.4 ± 3.2 mm. The ligament is closely connected to the posterior intermalleolar ligament, the inferior transverse ligament, and the tendinous sheaths of the posterior tibial and fi bular muscles. CONCLUSION: Conclusions: The obtained results of the study of linear and morphological parameters of PITFL should contribute to a better understanding of the anatomy of the posterior part of the ankle joint and improve surgical approaches to the treatment of posterior malleolus fractures and related PITFL injuries.
