“…The indentation load curve is shown in Fig 7. No correlation was seen between the indentation modulus and the yield point or stiffness. The pretest sample size analysis suggested that a difference in the yield point of 117 N could be detected; however, the standard deviations of the test results were substantially similar compared with those from previous studies (15). The present findings indicated that the yield point obtained with screw fixation was approximately 25% greater than that obtained with locking plate fixation, but the difference was not statistically significant.…”

“…The treatment of talus fractures can be complicated, and most researchers believe that displaced talar neck fractures require open reduction and internal fixation (5,15,16). With the introduction of newer implants, such as headless variable-pitch screws and locking plates, questions have arisen regarding the quality of these implants and their inherent advantages and disadvantages (9).…”

“…The posterior process of the talus has medial and lateral tubercles that allow the flexor hallucis longus tendon to pass in between (figure 3). Anteriorly, the head of the talus articulates with the navicular, forming the talonavicular joint 9. Talar fractures are a rare entity, accounting for only 1% of all lower extremity injuries 10.…”

Osseous injuries of the foot: an imaging review. Part 3: the hindfoot

Injuries to the foot are a common cause for presentation to the emergency department, and imaging is often used to aid in the diagnosis. The foot can be divided into three distinct anatomic regions: the forefoot, midfoot and hindfoot. Our manuscripts comprise a three-part imaging review in which we address the use of radiography as well as advanced imaging modalities. We provide pearls to radiographic interpretation and discuss prognostic implications and classification systems. Part 1 addresses forefoot injuries, part 2 reviews midfoot injuries and part 3 covers the hindfoot.

The aim of this study was to characterize ankle stability of total talar prosthesis (TTP) and to determine the effect of implant sizes on stability as well as the resistance to TTP dislocation. Twelve below‐knee cadaveric specimens were divided into two groups. Group 1 received a size matched implant and Group 2 received downsized implant by 5%. The stability assessment under fluoroscopy was performed for each cadaver in its native state. Following TTP insertion process, each then underwent evaluation of the TTP ankle stability. The stability of pre‐ and post‐TTP was compared. (1) Anterior drawer distance. (2) Talar tilt angle under varus and valgus stress. (3) Subtalar tilt angle under varus stress was measured. Finally, the dislocation test was performed using the aforementioned testing conditions, then the stress force was slowly increased from 0 to 350 N, during which time it was observed on fluoroscopy all the time. Compared to pre TTP ankles, varus and anterior drawer stress showed significant instability (p < 0.001–0.031). Only anterior drawer stress in smaller sized implants showed significant instability when compared to identical sized implants (p = 0.008). No dislocation was seen under varus, valgus, and subtalar stress. However, anterior dislocation was observed in all cases of smaller size implant group (p = 0.045). TTP implant was stable under valgus and subtalar stress. However, clinicians should pay attention to anterior instability. Notably, downsized implants should be considered carefully to minimize the chance of anterior dislocation.
