“…22 On the other hand, the average femur length in the Japanese population has been reported to be 395.7 mm. 23 Theoretically, it is thus easier for the 235 to 240 mm nails to exceed the femoral isthmus of the Japanese population. This might decrease the wiper motion, which we defined as repetitive motion of the distal nail inside the femoral canal.…”

Introduction: The TFN-ADVANCED Proximal Femoral Nailing System (TFNA) 235 mm (DePuySynthes) and Proximal Femoral Nail Antirotation (PFNA)-II 240 mm (DePuySynthes) were developed to obtain better stability for patients with trochanteric hip fractures without increasing surgical time and amount of blood loss. However, there are currently no studies concerning clinical and radiological outcomes of patients treated using these proximal femoral nails (PFNs) that have been performed in the Japanese population. The aim of this study was to retrospectively evaluate the clinical outcomes associated with 235 to 240 mm PFNs for Japanese patients >70 years old with trochanteric hip fractures who could walk independently before the injury. Materials and Methods: This study involved a retrospective analysis of data on trochanteric hip fracture patients who had undergone internal fixation from March 2016 to June 2018. The inclusion criteria were patients >70 years old with trochanteric hip fractures who could walk independently before the injury and were followed up for ≥3 months after surgery. Initially, 124 patients were identified, but 33 of these were excluded because other implants were used for internal fixation. Of the remaining 91 patients in whom PFNs were used at the time of internal fixation who were included for the perioperative evaluation, 66 patients followed up for ≥3 months were included in the clinical evaluations. Results: The average surgical time was 56.8 ± 19.6 minutes (range, 23-123 minutes). The average blood loss was 89 ± 41 mL (range, 0-245 mL). The union rate was 98%. Discussion: There were no cases of nail jamming, and all nails were successfully inserted below the end of the distal isthmus without additional reaming to dilate the canal. Conclusions: Proximal femoral nails were a useful implant in Japanese elderly patients with trochanteric hip fractures and gave comparable clinical outcomes despite the femoral length being short and occurrence of intensive bowing.

“…It is known that bone shape is influenced by the tensions experienced during development. As a result, habitual positions and locomotion patterns during growth can impact bone morphology (Aiello & Dean, 1990; Mizushima et al, 2016; Trinkaus, 1975). However, this variation can also be attributed to several factors, ranging from nutrition to climatic adaptation and locomotor efficiency (Allen, 1877, Bogin et al, 2002; Higgins & Ruff, 2011).…”

The analysis of the locomotor anatomy of Late Pleistocene Homo has largely focused on changes in proximal femur and pelvic morphologies, with much attention centered on the emergence of modern humans. Although much of the focus has been on changes in the proximal femur, some research has also been conducted on tibiae and, to a lesser extent, fibulae. With this in mind, we present one of the largest samples of the same population of human tibiae and fibulae from the Middle Pleistocene to determine their main characteristic traits and establish similarities and differences, primarily with those of Neanderthals and modern humans, but also with other Middle Pleistocene specimens in the fossil record. Through this study, we established that the Middle Pleistocene population from the Sima de los Huesos (Atapuerca, Burgos, Spain) had lower leg long bones similar to those of Neanderthals, although there were some important differences, such as bone length, which this fossil individuals resembled those of modern humans and not to Neanderthals. This fact is related to the crural index and leg length, even though we do not have any true association between femora and tibiae yet, it has implications for establishing locomotor efficiency and climate adaptation.

“…Further, given the central role of the growth and development period for establishing adult skeletal characteristics, investigating the habitual activity patterns of immature individuals can be particularly informative (Pearson & Lieberman, 2004). Several recent studies (e.g., Cowgill, 2010Cowgill, , 2014Harrington & Osipov, 2018;Mizushima et al, 2016;Osipov et al, 2016;Osipov et al, 2020) have examined diaphyseal robusticity in immature remains from archeological and paleoanthropological contexts to understand patterns of activity in these populations before adulthood. The study of activity patterns during growth can tell us much about group mobility, when children started engaging in adult habitual activities, as well as underlying factors affecting variation in bone adaptive responses.…”

Objectives As growth at the periosteal and endosteal surfaces varies with age, cross‐sectional geometric (CSG) properties derived from periosteal (“solid”) contours may not produce comparable results to those from endosteal and periosteal contours (“true”), contrary to findings from adults. Error in CSG properties derived from the “solid” sections is compared with “true” sections in a sample of archeologically derived skeletons with estimated dental ages ranging from 1.5 months to 23.5 years. Materials and Methods Cross sections were extracted from 3D surface models, and endosteal contours were located from biplanar radiographs for 56 femora and 59 humeri. Polar second moment of area (J), cross‐sectional shape (Imax/Imin), and polar section modulus (Zp) were calculated from solid and true sections. Relationships between solid and true properties were examined with least squares regression. Multiple regression examined the effect of age and % cortical area on solid section CSG error. Results While correlations were high (R2 = 0.72–0.99, all p < 0.001), the results indicate that solid CSG properties are not within an acceptable error range (%SEE of ≤8.0, and %PE of ≤5.0) of true CSG. Error was most affected by %CA, while estimated age was not correlated with %CA, %PE, or percent difference of true‐solid CSG. Discussion Periosteal contours alone should not be used to calculate CSG properties from individuals during the period of growth and development. Variation in bone growth and/or adaptive responses independent of age may account for the inconsistent age effects.
