INTRODUCTION The motion of the distal syndesmosis correlates highly with the instability, while an accurate kinematic description of the distal tibiofibular joint during normal gait has not previously been presented. MATERIAL AND METHODS Sixteen healthy syndesmoses of sixteen living subjects (8 male and 8 female) were studied during stance phase of the normal gait. Data of CT scanning were co...

OBJECTIVE The aim of this study was to investigate the effect of shoe design on the plantar pressure dynamics of patients with diabetic neuropathy during walking. RESEARCH DESIGN AND METHODS Three shoe design categories were tested. Total contact area and biomechanical variables in multiple areas under the foot were measured. RESULTS Shoes with a rocker bottom principle reduced pressure 35-...

We collected high-resolution plantar pressure distributions of seven bonobos during terrestrial bipedal and quadrupedal locomotion (N = 146). Functional foot length, degree of hallux abduction, and total contact time were determined, and plots, showing pressure as a function of time for six different foot regions, were generated. We also studied five adult humans for comparison (N = 13). Both l...

Plantar heel pain is a symptom commonly encountered by clinicians. Several conditions such as plantar fasciitis, calcaneal fracture, rupture of the plantar fascia and atrophy of the heel fat pad may lead to plantar heel pain. Injury to the tibial nerve and its branches in the tarsal tunnel and in the foot is also a common cause. Entrapment of these nerves may play a role in both the early phase...

Pressure ulcers are a frequent, but often preventable, occurrence among patients in acute care facilities, and the heel is one of the anatomical locations most commonly affected. Multiple clinical guidelines recommend the use of robust assessments to identify at-risk patients and the application of heel protection devices to reduce the likelihood of developing heel pressure ulcers. A quality im...

[Purpose] We aimed to evaluate the difference in the muscle activity between the double-leg heel raise (DHR) and treadmill walking. [Subjects] Thirty healthy males aged 21.5 ± 1.6 years (body mass 63.6 ± 9.3 kg, height 171.0 ± 4.5 cm) participated in the study. [Methods] Electromyograms were simultaneously recorded from both heads of the gastrocnemius and the soleus of the right side during the...

INTRODUCTION Aneurysmal bone cysts (ABCs) are blood filled fibrous tumor-like cysts that expand the bone giving it a blown out appearance. It is usually seen in the second decade. ABCs were first described by Jaffe and Litchensen in 1942. The exact etiology is unknown. One of the most widely accepted ideas was that aneurysmal bone cyst was a consequence of increased venous pressure and subseque...

Pressure sore is tissue ulceration due to unrelieved pressure, altered sensory perception, and exposure to moisture. Geriatric patients with organic problems and patients with spinal cord injuries are the high-risk groups. Soft tissues over bony prominences are the common sites for ulcer development. About 95% of pressure ulcers occur in the lower part of the body. Ischial tuberosity, greater t...

81 The discovery and popularization of roentgenography at the beginning of the century enabled the visualization of heel spurs.1 Wachter and Sonnenschein2 in 1915 correlated four cases of painful heels with calcaneal spurs; after all four patients returned for surgery following conservative care, the authors concluded that surgical intervention was the best treatment. Heel spur syndrome or plan...

Postmortem measurements were made of distances from skin surface to underlying bone/cartilage on 43 children (up to 8 y old; weights from 0.7 to 26.4 kg) to determine optimal sites and lengths of lancet tips for skin puncture of the heel, great toe, and middle finger. For measuring depths, a needle-like probe was devised that minimized disfigurement. As long as the infant's heel was available f...
