This study aimed to elucidate the relationship of prenatal and/or postnatal factors, including acquired factors, with the calcaneus stiffness index as measured by quantitative ultrasound (QUS-SI) in adolescents. We recruited 1,143 adolescents with a mean age of 14.8 ± 1.8 years (501 boys and 642 girls). The subjects' calcaneus QUS-SI was measured using an ultrasound bone densitometer. We also m...

In order to greatly improve the physical function of martial arts athletes, this topic studies effect high-protein food on athletes. Forty-five athletes in events took 5 g every day, 6 times a week for 4weeks, and left right forearm, calcaneus bone mineral density, venous blood was drawn detect metabolism biochemical indicators related function. The experimental results showed that density male...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013009954 DESCRIPTION A 22-year-old man was presented to our orthopaedic clinic with right ankle pain after an inversion injury. On physical examination, there was no swelling and range of motion of the ankle joint was normal. The only symptom was pain on the dorsal pa...

We report on a 45-yr-old male sports instructor with chronic pain and instability of the ankle. He was a recreational basketball player, but because of repeated ankle sprains and chronic subtalar pain this activity became impossible. The radiologic findings were compatible with the diagnosis of accessory calcaneus. In an initial therapeutic approach the patient was treated conservatively with t...

One hundred fifty-three subjects between the ages of 18 and 41 years (mean age, 26.2 years) with no history of congenital or traumatic deformity or foot problems walked along a 6-m walkway while the angular and linear displacement of the tibia, calcaneus, navicular, and first metatarsal was measured by means of an electromagnetic motion analysis system. Three-dimensional movement of the calcane...

An open fracture of the calcaneus with loss of substance is a challenging injury and requires specialized care, involves high costs, and demands attention despite its lower incidence. The main complications are osteomyelitis, pressure ulcers, and fistulas, as well as pain conditions in the lateral, medial, and plantar regions. This is due to the wide loss of tissue and the change in anatomical ...

Trabecular bone anisotropy, describing preferential trabecular co-alignment, is a proxy for its long-term loading history. anisotropy varies locally, thus rendering averaged calculations across an entire inutile. Here we present 3D mapping method using vector fields where each reflects the extent of local co-alignment elementary units surface. maps hundreds thousands vectors were visualized by ...

Os calcaneus secundarius is one of several accessory ossicles of the foot that have been identified as normal variants of skeletal development. It may cause ankle pain and may mimic an avulsion fracture of the anterior calcaneal process. A twenty-year-old male was admitted to our institution with right ankle pain following an inversion injury. An axial CT image of the patient's right ankle reve...

Dislocation of the peroneal tendons associated with calcaneus fractures should be repaired during fracture fixation to prevent complications. The only documented approach for repair is by proximal extension of the vertical limb of the lateral extensile approach to the calcaneus. However, enlarging the inherently fragile calcaneus flap places it at further risk of damage. Using a separate anteri...

a case of bilateral intraosseous tumor of the calcaneus with different mri imaging is presented. on the left, radiological findings suggest intraosseous lipoma, but on the right-sided lesion, imaging studies were not convincing. the microscopic report showed foreign body granulomatous reaction, a rare clinical pathological discordant.
