PURPOSE: A too-long anterior process of the calcaneus is a common cause of pain and hind-foot instability. Our goal was to evaluate the early results of arthroscopic resection in terms of static foot disorders in children and adolescents. METHODS: We retrospectively studied 11 ft (10 patients). The inclusion criteria were treatment of TLAP by arthroscopic resection and a minimum follow-up period of six months. Surgery was indicated in cases with persistent symptomatic TLAP resistant to orthopaedic treatment...

In this article, we report a case of transformation of a benign giant cell tumor (GCT) of the calcaneus into an epithelioid angiosarcoma. The patient presented to our service in 2003 and was followed until 2014. Transformation occurred 11 years after curettage, cryotherapy, cementation, and a well-documented disease-free interval. Longitudinal radiographs, magnetic resonance imaging, and histopathology were evaluated by the same medical team. There are only a few case reports and case series of malignancy associated with GCT of bone...

Calcaneal apophyseal fractures are usually considered sport-related injuries. Previous repetitive microtrauma has been proposed as a predisposing factor for such injuries. However, unlike previously reported cases, in our patient, the fracture resulted from acute trauma after stepping on uneven ground. Although the first treatment option for such cases is closed reduction, most cases will require surgical treatment. Furthermore, lesions accompanying this injury have not been sufficiently considered. We report the case of a 9-year-old female with a calcaneal apophyseal fracture treated by fixation of the avulsed proximal part of the apophysis using Kirschner wires and a cerclage wire...

The heel comprises the epidermis, minimal subcutaneous tissue, a dense septum, and the calcaneus. Injury to any of these structures can impair the ability to walk. The soft tissue or calcaneal bone can be injured by trauma. Injuries incurred in war are usually high-energy traumas caused by weapons such as rifles, rockets, and land mines. Such injuries can be life threatening and involve the loss of tissue, including skin, soft tissue, bone, and neurovascular tissue. Two main treatment protocols are used for such injuries with large tissue defects: amputation and reconstruction...

The diagnostic performance of densitometry is inadequate. New techniques of non-invasive evaluation of bone quality may improve fracture risk prediction. Testing the value of these techniques is the goal of the QUALYOR cohort. INTRODUCTION: The bone mineral density (BMD) of postmenopausal women who sustain osteoporotic fracture is generally above the World Health Organization definition for osteoporosis. Therefore, new approaches to improve the detection of women at high risk for fracture are warranted...

BACKGROUND AND OBJECTIVE: Flatfeet can be evaluated by measuring the calcaneal-fifth metatarsal angle on a weight-bearing lateral foot radiograph. This study aimed to develop an automated method for determining the calcaneal-fifth metatarsal angle on weight-bearing lateral foot radiograph. METHOD: The proposed method comprises four processing steps: (1) identification of the regions including the calcaneus and fifth metatarsal bones in a foot image; (2) delineation of the contours of the calcaneus and the fifth metatarsal; (3) determination of the tangential lines of the two bones from the contours; and (4) determination of the calcaneal-fifth metatarsal angle between the two tangential lines as arch angle...

Ultrasound bone mass measurement has been postulated as a valuable bone-health assessment tool for primary care. The aim of this study was to analyse the possible relationship between the SPTBN1, RSPO3, CCDC170, DKK1, GPATCH1, and TMEM135 genes, with calcaneal quantitative ultrasound (QUS) in a population of young adults. These genes were first associated with broadband ultrasound attenuation (BUA) in the GEFOS/GENOMOS study. A cross-sectional study was conducted on 575 individuals (mean age 20.41 ± 2...

In recent years, some authors have reported accessory anterolateral talar facet impingement with flatfoot including peroneal spastic flatfoot. Conversely, to our knowledge, no case report has been published about accessory anterolateral talar facet impingement with tibialis spastic varus foot. We report the first case in a 22-year-old man with intellectual disability, bilateral cleft hands and type 1 diabetes mellitus. Since spraining his left ankle over a year earlier, he experienced left sinus tarsi pain while standing and walking...

The purpose of this study is to investigate the compensatory correlation between knee and hindfoot in patients with rheumatoid arthritis (RA). This cross-sectional study included 218 patients (407 lower extremities). Radiographs of the hindfoot and full-length posteroanterior hip-to-calcaneus standing radiographs were evaluated. The destruction of the hindfoot was evaluated using the Larsen grading system. The coronal angular deformity of the knee and hindfoot was evaluated by the femorotibial angle (FTA) and the angle between the tibial shaft and the entire hindfoot (tibiohindfoot angle, THFA)...

[Purpose] Severe calcaneus misalignment is correlated with low back pain, and affects pelvic alignment. However, little has been published with regard to the influence of pronation and supination on trunk alignment. Therefore, the present study aimed to investigate the influence of calcaneal inversion on pelvic and trunk alignment. [Subjects and Methods] A 3-dimensional motion analysis system was used to assess pelvic and trunk alignment in 10 healthy male subjects with unilateral and bilateral calcaneus inversion...

Intraosseous lipoma is a rare benign bone tumor that has been reported to occur in the calcaneus and long bones. The etiology of intraosseous lipoma is unknown, although several theories have been proposed. The majority of the cases of intraosseous calcaneal lipoma reported in the literature were localized in the anterior portion of the calcaneus and were treated by curettage and bone grafting. However, for larger lipomas, no specific treatment protocol has been developed to date. We herein present a rare case involving a large intraosseous lipoma of the calcaneus in a 36-year-old man following hindfoot trauma...

Measuring foot kinematics using optical motion capture is technically challenging due to the depth of the talus, small bone size, and soft tissue artifact. We present a validation of our biplane X-ray system, demonstrating its accuracy in tracking the foot bones directly. Using an experimental linear/rotary stage we imaged pairs of tali, calcanei, and first metatarsals, with embedded beads, through 30 poses. Model- and bead-based algorithms were employed for semi-automatic tracking. Translational and rotational poses were compared to the experimental stage (a reference standard) to determine registration performance...

BACKGROUND: Displaced intra-articular calcaneal fractures (DIACFs) can have long-term consequences in terms of foot pain and disability. This injury frequently occurs in the context of polytrauma patients and its influence in long-term functional prognosis is well known. The purpose of this study is to compare the etiology, severity, and functional outcome of the operated DIACFs between polytrauma patients and isolated cases. METHODS: Eighty-six patients with operated displaced intra-articular calcaneal fractures through open reduction and internal fixation (ORIF) were managed at our institution between January 1, 2008 and December 31, 2015...

Objectives: The complications associated with iliac crest bone-graft harvest have resulted in the development of alternative harvest sites. Lower extremity alternative sites that have been reported for foot and ankle procedures include greater trochanter, proximal tibia, distal tibia, and calcaneus. These sites have been studied in terms of complications, postoperative pain, and quality of the harvested bone. The long-term effect of the harvest on the bone of the calcaneus has not been reported...

Trabecular bone of the human calcaneus is subjected to extreme repetitive forces during endurance running and should adapt in response to this strain. To assess possible bone functional adaptation in the posterior region of the calcaneus, we recruited forefoot-striking runners (n = 6), rearfoot-striking runners (n = 6), and non-runners (n = 6), all males aged 20-41 for this institutionally approved study. Foot strike pattern was confirmed for each runner using a motion capture system. We obtained high resolution peripheral computed tomography scans of the posterior calcaneus for both runners and non-runners...

The anatomical design of the human foot is considered to facilitate generation of bipedal walking. However, how the morphology and structure of the human foot actually contribute to generation of bipedal walking remains unclear. In the present study, we investigated the three-dimensional kinematics of the foot bones under a weight-bearing condition using cadaver specimens, to characterize the innate mobility of the human foot inherently prescribed in its morphology and structure. Five cadaver feet were axially loaded up to 588 N (60 kgf), and radiographic images were captured using a biplane X-ray fluoroscopy system...

Calcaneal fractures are notoriously difficult to treat and wound complications occur often. However, owing to the rare nature of these fractures, clinical trials on this subject are lacking. Thus, biomechanical studies form a viable source of information on this subject. With our systematic review of biomechanical studies, we aimed to provide an overview of all the techniques available and guide clinicians in their choice of method of fracture fixation. A literature search was conducted using 3 online databases to find biomechanical studies investigating methods of fixation for calcaneal fractures...
