OBJECTIVE: The quantitative ultrasound (QUS) method has been recognized as an optimal screening tool for assessing bone mass status. The aim of this study was to provide standardized values for bone health status measured by the QUS technique based on age, sex, and body mass index (BMI). METHODS: The study population consisted of 1322 healthy individuals (822 females and 500 males) aged 14-25 years. Bone mass in both calcaneus was estimated with QUS to obtain Broadband ultrasound attenuation (BUA) (dB/MHz)...

Vitamin D deficiency is more common in Blacks, yet Blacks have lower prevalence of bone fragility fractures or osteoporosis than Whites. Broadband ultrasound attenuation (BUA) has been used to explore the association between serum 25(OH)D levels and bone quality in White and non-white populations. We investigated serum 25(OH)D status with corresponding BUA measurements assessed cross sectionally in a cohort of 232 Blacks and 260 Whites, aged 30-95 years who were part of the calibration study of the large Adventist Health Study-2 (AHS-2)...

Although ankle arthrodesis is the reference standard for end-stage ankle arthritis, loss of mobility and adjacent joint arthritis are consequences that alternatives to arthrodesis attempt to avoid. The purpose of the present study was to report the clinical results of interpositional arthroplasty using acellular dermal matrix in 4 patients (age 32 to 42 years) for the treatment of advanced ankle osteoarthritis. The primary findings included relief of pain, with improvement in tibiotalar joint range of motion from a mean of 16...

We report a case of valgus ankle degenerative arthritis due to chronic isolated deltoid insufficiency combined with tibial varus that was treated successfully with ankle joint preserving surgery. A 63-year-old male complained of right lateral ankle pain with 10 minutes of maximal pain-free walking time. The assessed American Orthopaedic Foot and Ankle ankle-hindfoot scale score was 33 points. The ankle joint showed 18° of valgus deformity with 6° of tibia varus. Medial displacement calcaneal osteotomy, supramalleolar open wedge osteotomy, and deltoid ligament imbrication were performed...

The objective of the present investigation was to examine the effect of cuboid height on the presence of plantar midfoot ulceration and the relationship of cuboid height to other commonly performed radiographic parameters during evaluation of midfoot Charcot neuroarthropathy. A retrospective analysis was performed of 68 feet in 60 subjects who met the inclusion criteria. We did not observe statistically significant differences in the presence of a plantar midfoot ulceration when considering a cuboid height threshold of 0...

OBJECTIVE: We examined the effect of low-intensity pulsed ultrasound (LIPUS) on bone strength in osteoporotic elderly residents. MATERIALS AND METHODS: This was a randomized controlled trial. Elderly residents with osteoporosis in a long-term care facility were treated with LIPUS (oscillation frequency 100 KHz) that involved treatment of the heel bone for 2 minutes a day. The selection of the treated heel was decided randomly with a personal computer. The heel bone mineral density before and after treatment was measured by calcaneal quantitative ultrasound (GE-1000 Express)...

INTRODUCTION: Both the overall shape of the calcaneus and anatomical reduction of joint congruity are important prognostic factors. However, there is a significant lack of biomechanical data supporting the clinical importance of calcaneus height, length and heel width. The objective of this study was to determine the effects of abnormal calcaneus morphology on ankle-hindfoot biomechanics. HYPOTHESIS: The normal biomechanics of the ankle-hindfoot would be severely disrupted by the abnormal calcaneus morphology...

BACKGROUND: Large Achilles tendon defects pose a treatment challenge. The standard treatment with a turndown flap requires a large extensile incision, puts the sural nerve at risk, and demands slow, careful rehabilitation. Dual allograft semitendinosus reconstruction is a new clinical alternative that has the theoretical advantages of a smaller incision, less dissection, and a stronger construct that may allow for faster rehabilitation. QUESTIONS/PURPOSES: In a cadaver biomechanical model, we compared the dual allograft semitendinosus reconstruction with the myofascial turndown in terms of (1) mechanical strength and resistance to deformation and (2) failure mechanisms in reconstruction of large segmental Achilles defects...

REVIEW

Calcaneal cysts and lipomas are relatively rare, benign bone lesions. They are similar in many ways, including in their location and radiological appearance, but their content differs. Cysts contain fluid whereas lipomas contain fat, although some lesions may exhibit a mixed content. The pathogenesis of the two entities is the subject of controversy. The theory that calcaneal cysts may result from lipomatous necrosis has been widely suggested in the literature, but no such progression has ever been shown. The contrary hypothesis has also been considered, i...

Metaphyseal and proximal diaphyseal fractures of the lateral column metatarsals can have problems with healing. In particular, those involving the fifth metatarsal have been associated with a high nonunion rate with nonoperative treatment. Although intramedullary screw fixation results in a high union rate, delayed healing and complications can occur. We describe an innovative technique to treat both acute and chronic injuries involving the metatarsal base from the metaphysis to the proximal diaphyseal bone of the fourth and fifth metatarsals...

Locomotor mode is an important component of an animal's ecology, relating to both habitat and substrate choice (e.g., arboreal versus terrestrial) and in the case of carnivores, to mode of predation (e.g., ambush versus pursuit). Here, we examine how the morphology of the calcaneum, the 'heel bone' in the tarsus, correlates with locomotion in extant carnivores. Other studies have confirmed the correlation of calcaneal morphology with locomotion behaviour and habitat. The robust nature of the calcaneum means that it is frequently preserved in the fossil record...

We present a retrospective review of 8 patients (6 women and 2 men, with an age range of 46-80 years; mean age, 60.2 years) in whom sonography was used to diagnose a calcaneal stress fracture. Sonography was performed because of a clinical suspicion of soft tissue injuries. Two patients were first assessed by standard radiography; for the remaining patients, sonography was the first imaging technique used. Patients were subsequently examined by magnetic resonance imaging, except for 1 patient in whom the diagnosis was made only on a clinical-sonographic correlation...

The purpose of this study was to compare the exposure of the posterior facet with the extensile lateral (EL) approach compared with the sinus tarsi (ST) approach. We hypothesized that the ST approach will provide a similar exposure of the posterior calcaneal facet. A total of 8 sequential ST then EL approaches were performed on cadavers. Calcaneal landmarks were identified by visualization or palpation. Calibrated digital photographs of the posterior facet and lateral calcaneal body were obtained from standardized positions and used to calculate the exposed surface area...

Calcaneal fractures are potentially devastating injuries. To effectively manage calcaneal fractures, surgeons must understand the anatomy of the calcaneus as well as the surgical techniques necessary to restore normal biomechanics of the foot. Surgeons also must understand calcaneal fracture patterns and classifications; initial management techniques, surgical indications and rationale, temporizing management techniques, surgical approaches, definitive management techniques, and postoperative management for calcaneal fractures; as well as outcomes and common complications of calcaneal fractures...

Traumatic injury to the foot and ankle can result in long-term disability, which may have substantial negative implications on a patient's functional outcomes and quality of life. The diagnosis and appropriate management of these challenging injuries are not always agreed on or straightforward. In particular, the appropriate diagnosis and management of distal tibiofibular syndesmotic injuries as well as the surgical approach and role of primary subtalar arthrodesis for intra-articular calcaneal fractures are controversial...

Carotenoids are found in abundance in fruit and vegetables, and may be involved in the positive association of these foods with bone health. This study aimed to explore the associations of dietary carotenoid intakes and plasma concentrations with bone density status and osteoporotic fracture risk in a European population. Cross-sectional analyses (n 14 803) of bone density status, using calcaneal broadband ultrasound attenuation (BUA) and longitudinal analyses (n 25 439) of fracture cases were conducted on data from the prospective European Prospective Investigation into Cancer and Nutrition-Norfolk cohort of middle-aged and older men and women...

In a commingled context, assessing that a talus and a calcaneus correspond to the same individual could become a primary step for accurately sorting human remains. For this purpose, the lengths and widths of the trochlea, posterior calcaneal articular surface, and posterior talar articular surface were measured in 197 individuals (105 males, 92 females) from the Athens Collection. A total of 12 highly accurate equations for reassociating tali and calcanei were developed, using simple and multiple linear regression analysis and they were found to be suitable for sorting commingled human remains...

The diagnostic criteria of osteoporosis were established based on bone mineral density (BMD). Therefore, BMD measured by dual energy X-ray absorptiometry has been recognized as the gold standard to diagnose osteoporosis. However, discrepancies between fracture risk and BMD have been recognized. Bone is composed of collagen scaffold reinforced by hydroxyapatite. Both protein scaffold and hydroxyapatite are involved in bone quality. BMD may indicate bone mineralization but potentially fail to assess the protein scaffold...
