Introduction: Primary Non-Hodgkin’s lymphoma (NHL) of the bone is a rare condition. Calcaneus is also an uncommon site for this kind of lymphoma. Case Presentation: We hereby present a case of primary non-Hodgkin’s lymphoma of the calcaneus, which was diagnosed and treated at our hospital. The patient had a minor twisting trauma of his ankle but symptoms were present for one year after trauma. ...

The purpose of this study was to quantify movement coupling at the ankle during the stance phase of running using bone-mounted markers. Intracortical bone pins with reflective marker triads were inserted under standard local anaesthesia into the calcaneus and the tibia of five healthy male subjects. The three-dimensional rotations were determined using a joint coordinate system approach. Moveme...

Avulsion calcaneal tuberosity fracture is an uncommon but potentially serious condition. Recent studies on the epidemiology of these specific fractures have demonstrated that avulsed calcaneal fractures account for 1.3% of all calcaneal fractures.It is therefore understandable that little has been written about these fractures. This type of injuries is usually caused by sudden muscular contract...

OBJECTIVE To determine the areas presenting risk in six zones of the calcaneus, and to quantify the risks of injury to the anatomical structures (artery, vein, nerve and tendon). METHOD Fifty-three calcanei from cadavers were used, divided into three zones and each subdivided in two areas (upper and lower) by means of a longitudinal line through the calcaneus. The risk of injury to the anatom...

The longitudinal arch is one of the hallmarks of the human foot but its evolutionary history remains controversial due to the fragmentary nature of the fossil record. In modern humans, the presence of a longitudinal arch is reflected in the angular relationships among the major surfaces of the human talus and calcaneus complex, which is also known as the rearfoot. A complete talus and calcaneus...

PURPOSE The influence of alendronate (ALN) treatment on the quantitative ultrasound parameters of the calcaneus remains to be established in Japanese patients. The aim of the present clinical practice-based observational study was to examine the influence of ALN treatment for 1 year on the speed of sound (SOS) of the calcaneus and bone turnover markers in postmenopausal Japanese women with oste...

OBJECTIVE The purpose of this study was to investigate the association between two genetic polymorphisms (PvuII and XbaI restriction fragment length polymorphisms, RFLPs) of the estrogen receptor-alpha (ER1) gene and the quantitative ultrasound (QUS) parameters at the calcaneus. SUBJECTS AND METHODS Two hundred and sixty-six Korean vegetarian men, mean age 50.9+/-12.0 years (range 26-80), wer...

Five healthy young men were studied during 24-30 wk of continuous bed rest. During the first 12 wk of bed rest, untreated subjects increased calcium excretion in the urine by 109 mg/day and in the feces by 147 mg/day. The rate of total body calcium loss was 0.5-0.7% per month. Losses of central calcaneus mineral, assessed by gamma ray transmission scanning, occurred at a tenfold higher rate, wh...

Radiographs have been used as tools of diagnosis, prognosis and in selection and evaluation of treatment modalities of various types of deformities and fractures of the foot (Katz et al., 1997; Igbibi & Mutesasira, 2003; Dooley et al., 2004; Dobbs et al., 2006; Westberry et al., 2007; Aminian & Sangeorzan, 2008; Radler et al., 2010). Lateral talocalcaneal angle (L TCA) is an angle formed by a l...

Bone lead levels for 367 active and 14 retired lead smelter workers were measured in vivo by X-ray fluorescence in May-June 1994. The bone sites of study were the tibia and calcaneus; magnitudes of concentration were used to gauge lead body burden. Whole blood lead readings from the workers generated a cumulative blood lead index (CBLI) that approximated the level of lead exposure over time. Bl...
