Patas monkeys (Erythrocebus patas) living in African savanna woodlands and grassland habitats have a locomotor system that allows them to run fast, presumably to avoid predators. Long fore- and hindlimbs, long foot bones, short toes, and a digitigrade foot posture were proposed as anatomical correlates with speed. In addition to skeletal proportions, soft tissue and whole body proportions are important components of the locomotor system. To further distinguish patas anatomy from other Old World monkeys, a comparative study based on dissection of skin, muscle, and bone from complete individuals of patas and vervet monkeys (Cercopithecus aethiops) was undertaken. Analysis reveals that small adjustments in patas skeletal proportions, relative mass of limbs and tail, and specific muscle groups promote efficient sagittal limb motion. The ability to run fast is based on a locomotor system adapted for long distance walking. The patas’ larger home range and longer daily range than those of vervets give them access to highly dispersed, nutritious foods, water, and sleeping trees. Furthermore, patas monkeys have physiological adaptations that enable them to tolerate and dissipate heat. These features all contribute to the distinct adaptation that is the patas monkeys’ basis for survival in grassland and savanna woodland areas.

The purpose of this article is to determine the orientation and relative position of the foot bones in Weight Bearing CT, highlighting the effect of the load and the shoe with the heel. Thanks to a Cone Beam CT (OnSight 3D Extremity System, Carestream) equipment, three scans of the foot of a healthy young subject were carried out in three conditions: "unloading", "loading", and wearing a shoe with "heel". In order to assess the accuracy of the articular angles of the foot through non-invasive measurements, a measurement was performed by Gait-Analysis with passive markers in the same conditions. The effect of the "load" resulted in a significant alteration of the foot posture especially in the sagittal plane, with crushing of the longitudinal medial arch. The heeled shoe involves enormous deformations at the level of the metatarsophalangeal joints and the ankle.

Chronic foot pain in pediatric age group is less common. The usual differential diagnosis may vary from musculoskeletal injury to serious diseases such as osteomyelitis. Benign bone tumor such as osteoid osteoma of foot is exceedingly rare in this age group. Here we present a rare case of osteoid osteoma of cuboid mimicking osteomyelitis. Patient was managed conservatively by Non-steroidal Anti-inflammatory drugs (NSAIDs) with good clinical outcome. Osteoid osteoma of foot bones should be kept in mind in cases with normal blood parameters.

AbstractThe diagnostic value of animal remains from archaeological sites is discussed in the following order of importance of the various osteological elements which can be used for interpreting the fauna they represent: teeth, skull fragments, articular ends of limb bones, foot bones, portions of the pectoral and pelvic girdles, and vertebrae.
