Internal Architecture of the Talus

Abstract

These findings may help in better understanding of fracture lines in the talus,which could improve internal fixation techniques, and the design of talar prostheses.

Bone Microarchitecture of the Talus Changes With Aging

“…The subsidence of the talar component in total ankle arthroplasty is an important reason for implant failures in older patients, which leaves open the question as to whether some age-related changes do occur. Despite previous descriptions of the talar microarchitecture, these studies were either just descriptive in nature [4,21,34] or focused on the evaluation of the talar body only [18,26,39] without consideration of age-or sex-related differences. In this study, we were able to show an age-related talar bone loss, which predominantly affects the talar body rather than the neck or head, regardless of sex.…”

“…The talus has no attachments of muscles, or fasciae, which could support the absorption of applied loads [2,27]. Hence, its microarchitecture reflects its sole ability to endure great compressive and tensile forces during walking, running, and jumping distributing them from the talus to the adjacent bones and therefore varies in different regions of interest (ROIs) [4,34,39]. Because the talar body has a pronounced subchondral bone lamella, enormous axial loading forces resulting from high-impact injuries are necessary to cause talar fractures [21,27,36].…”

“…It is noteworthy that the anatomical partner of the talus for conferring the contact energy of the foot to the ground, the calcaneus, displays age-related changes in its microarchitecture similar to the proximal humerus or the distal radius [7,8,37]. Although there have been a number of histological analyses of talar microarchitecture, the effects of age and sex on talar microarchitecture changes remain poorly characterized [4,18,21,34,39].…”

Internal Architecture of Human Tali

“…As a result, the body of the talus has predominantly vertical trabeculae, running superiorly to inferiorly [1]. These findings may help in better understanding of fracture lines in the talus, which could improve internal fixation techniques, and the design of talar prosthesis [2]. MATERIALS AND METHODS Source of data: 30 tali were dissected out from the formalin fixed lower limbs available at the Department of Anatomy of KVG Medical College, Sullia and they were dried.…”

“…According to Wood Jones [5], two sets of arched lamellae (one set running from the trochlear surface to the posterior calcaneal facet and other from the trochlear surface to the neck) were present, but the present study did not correspond to his finding. According to Athavale [2], two sets of lamellae were observed in the body of the talus. One set was descending from the posterior two-thirds of the lateral part of trochlear surface onto the posterior calcaneal facet of the talus.…”
