BACKGROUND The purpose of this study was to determine the degree to which pressure on the plantar aspect of the forefoot is reduced following percutaneous lengthening of the Achilles tendon in diabetic patients who are at high risk for ulceration of the foot. METHODS Ten diabetic patients who had a history of neuropathic plantar ulceration of the forefoot were enrolled in a laboratory gait tr...

Ambient temperature and physical activity modulate bone elongation in mammals, but mechanisms underlying this plasticity are a century-old enigma. Longitudinal bone growth occurs in cartilaginous plates, which receive nutritional support via delivery of solutes from the vasculature. We tested the hypothesis that chronic exercise and warm temperature promote bone lengthening by increasing solute...

The lower eyelid retractors consist of double layers, the posterior layer of which is the main tractional component. Therefore, shortening of the posterior layer of the lower eyelid retractors causes lower eyelid retraction or cicatricial entropion. Based on this concept, we report a modified lower eyelid lengthening surgery involving complete recession of the posterior layer of the lower eyeli...

Implantable limb lengthening using noninvasively adjusted telescopic nails dates back to 1983. The newest technology is the Precice (Ellipse Technologies). A retrospective study of the first 65 Precice nails was carried out for the treatment of limb length discrepancy (unilateral) and short stature (bilateral). Successful lengthening was achieved in all patients. There were numerous distraction...

BACKGROUND and purpose Limb lengthening is performed for a diverse range of orthopedic problems. A high rate of complications has been reported in these patients, which include motor and sensory loss as a result of nerve damage. We investigated the effect of limb lengthening on peripheral nerve function. PATIENTS AND METHODS 36 patients underwent electrophysiological testing at 3 points: (1) ...

Clinical series of primary epiphyseal and metaepiphyseal tubercular osteomyelitis are few. The purpose of our study was to retrospectively review the presentation, healing response and functional results of 8 such cases in children. MATERIAL AND METHODS The patients were evaluated for pain, deformity, range of motion, limb length discrepancy (if any) and recurrence. Serial radiographs of the ...

When people make decisions, do they give equal weight to evidence arriving at different times? A recent study (Kiani et al., 2008) using brief motion pulses (superimposed on a random moving dot display) reported a primacy effect: pulses presented early in a motion observation period had a stronger impact than pulses presented later. This observation was interpreted as supporting the bounded dif...
