Bone Position and Ligament Deformations of the Foot From CT Images to Quantify the Influence of Footwear in Feet.

Front Bioeng Biotechnol 2020 19;8:560. Epub 2020 Jun 19.

Mines Saint-Etienne, Univ Lyon, Univ Jean Monnet, INSERM, U 1059 Sainbiose, Centre CIS, Saint-Étienne, France.

The mechanical behavior of the foot is often studied through the movement of the segments composing it and not through the movement of each individual bone, preventing an accurate and unambiguous study of soft tissue strains and foot posture. In order to describe the internal behavior of the foot under static load, we present here an original methodology that automatically tracks bone positions and ligament deformations through a series of CT acquisitions for a foot under load. This methodology was evaluated in a limited clinical study based on three cadaveric feet in different static load cases, first performed with bare feet and then with a sports shoe to get first insights on how the shoe influences the foot's behavior in different configurations.

Skeletal Radiol 2020 Jun 24. Epub 2020 Jun 24.

Service d'imagerie Guilloz, hôpital central, CHRU de Nancy, 29 avenue du Maréchal-de-Lattre-de-Tassigny, 54035, Nancy Cedex, France.

A wide variety of pathologies can affect the hallux sesamoid complex of the foot, including traumatic, micro traumatic, degenerative, inflammatory, vascular, infectious, and neoplastic conditions. Symptoms are quite nonspecific, mainly related to pain in the plantar surface of the first metatarsal head. In this context, imaging is important for the etiologic diagnosis of hallux sesamoid complex pathology with implications in patient management. Read More

Weight-bearing CT Scans in Foot and Ankle Surgery.

J Am Acad Orthop Surg 2020 Feb 21. Epub 2020 Feb 21.

From the Foot and Ankle Service, Department of Orthopedic Surgery, Hospital for Special Surgery, New York, NY.

Weight-bearing CT (WBCT) scans of the foot and ankle have improved the understanding of deformities that are not easily identified on radiographs and are increasingly being used by orthopaedic surgeons for diagnostic and preoperative planning purposes. In contrast to standard CT scans, WBCT scans better demonstrate the true orientation of the bones and joints during loading. They have been especially useful in investigating the alignment of complex pathologies such as adult-acquired flatfoot deformity in which patients have been found to have a more valgus subtalar joint alignment than in a normal cohort and high rates of subfibular impingement.

Adv Orthop 2020 3;2020:1852025. Epub 2020 Jan 3.

Albany Medical Center, Albany, NY, USA.

The bony and ligamentous structure of the foot is a complex kinematic interaction, designed to transmit force and motion in an energy-efficient and stable manner. Visible deformity of the foot or atypical patterns of swelling should raise significant concern for foot trauma. In some instances, disruption of either bony structure or supporting ligaments is identified years after injury due to chronic pain in the hindfoot or midfoot. Read More

Radiographic measurements of the talus and calcaneus in the adult pes planus foot type.

Am J Phys Anthropol 2020 04 12;171(4):613-627. Epub 2020 Jan 12.

Department of Anthropology, University of Washington, Seattle, Washington.

Objective: A distinctive feature of the modern human foot is the presence of a medial longitudinal arch when weight-bearing. Although the talus and calcaneus play a major role in the structure and function of the human foot, the association between the morphology of these bones and longitudinal arch height has not been fully investigated. A better understanding of this relationship may assist in the interpretation of pedal remains of fossil hominins, where features of the foot and ankle morphology have been described as providing evidence for the presence of a longitudinal arch.

Pathoanatomy of the Jones Fracture in Male University Soccer Players.

Am J Sports Med 2020 02 30;48(2):424-431. Epub 2019 Dec 30.

Department of Orthopaedic Surgery, Kishima Honin Hospital, Osaka, Japan.

Background: Jones fractures are relatively common in soccer players and require an extended recovery period because this type of fracture has a high incidence of delayed union, nonunion, and refracture. There has been some previous research on risk factors for Jones fracture, but no study has yet investigated the effect of the length of the fifth metatarsal bone and the positional relationship of the articular surface of the fifth metatarsal bones and the tarsal bones. Clarification of the characteristics of the foot structure that predispose soccer players to Jones fracture may aid in the prevention of this injury. Read More

Reconstruction with β-tricalcium phosphate for giant cell tumor of the talus.

Foot (Edinb) 2020 Mar 30;42:101643. Epub 2019 Sep 30.

Department of Orthopaedic Surgery, Graduate School of Medicine, Kyoto University, Kyoto 606-8507, Japan.

Giant cell tumor of bone (GCTB) is a locally aggressive tumor, commonly occurs in the long bones, and is rare in the talus and the foot. The talus is a weight-bearing bone and strut reconstruction is preferred. Reconstruction with low porosity β-tricalcium phosphate (β-TCP) blocks is reported for GCTB in the knee. Read More

The incision strategy for minimizing sural nerve injury in medial displacement calcaneal osteotomy: a cadaveric study.

J Orthop Surg Res 2019 Nov 12;14(1):356. Epub 2019 Nov 12.

Department of Orthopaedic Surgery, Chuncheon Sacred Heart Hospital, Hallym University, 77, Sakju-ro, Chuncheon-si, Gangwon-do, 200-704, Republic of Korea.

Background: The skin incision for medial displacement calcaneal osteotomy (MDCO) often damages the sural nerve. We aimed to identify the practical reference area in which the surgeon can incise the skin to minimize the injury of the sural nerve during MDCO.

Methods: The foot and ankles of 20 cadavers were dissected. Read More

Can skeletal surface area predict in vivo foot surface area?

J Anat 2020 Jan 12;236(1):72-84. Epub 2019 Nov 12.

School of Natural Sciences and Psychology, Faculty of Science, School of Biological and Environmental Sciences, Liverpool, UK.

The surface area of feet in contact with the ground is a key morphological feature that influences animal locomotion. Underfoot pressures (and consequently stresses experienced by the foot), as well as stability of an animal during locomotion, depend on the size and shape of this area. Here we tested whether the area of a skeletal foot could predict in vivo soft tissue foot surface area. Read More

Osteoid osteoma of the sesamoid bone: An unusual localization.

J Clin Orthop Trauma 2019 Nov-Dec;10(6):1065-1067. Epub 2018 Oct 28.

Department of Orthopaedic Surgery, University Hospital, Sahloul, Sousse, Tunisia.

Osteoid osteoma is the most common benign bone tumor because it accounts for 10-12% of all these tumors. Localized most often with long bones (75% of cases), especially in the tibia and femur, osteoid osteoma can evoke other etiologies, especially when it is juxta-articular. We report the case of an osteoid osteoma of the sesamoid in a 23-year-old patient with no particular history who presented pain at the root of his hallux evolving for 6 months. Read More

Improved metabolic control using glucose monitoring systems leads to improvement in vibration perception thresholds in type 1 diabetes patients.

Acta Diabetol 2020 Apr 8;57(4):433-438. Epub 2019 Nov 8.

Department of Clinical Sciences, Endocrinology, Lund University, Jan Waldenströmsgata 24, 205 02, Malmö, Sweden.

Aims: Few studies have examined how improved metabolic control might influence vibration perception thresholds (VPTs). The aim of this study was to evaluate if improved HbA can influence vibration thresholds in adults with type 1 diabetes (T1DM).

Methods: VPTs were investigated at six frequencies (4-125 Hz) using VibroSense Meter in the sole of the foot at two occasions in 159 T1DM patients, at the heads of the first and fifth metatarsal bones, i. Read More

Conservative treatment of Freiberg's infraction using foot orthoses: A tale of two prescriptions presented as a case study to open debate.

Foot (Edinb) 2019 Dec 27;41:59-62. Epub 2019 Jul 27.

Centre for Biomechanics and Rehabilitation Technologies, Staffordshire University, Leek Road, Stoke-on-Trent ST4 2DF, UK. Electronic address:

'Freiberg's infraction or disease' is an osteonecrotic process primarily affecting the 2 & 3 metatarsal heads. Early diagnosis is difficult, and the underlying pathogenesis remains unclear. Surgical options for late disease have been widely reported in the literature, yet details on conservative management for the early stages of Freiberg's are largely absent. Read More

Analysis of congruence for talar dome geometry among tali of different sizes.

Foot (Edinb) 2019 Dec 29;41:51-58. Epub 2019 Sep 29.

Department of Civil and Environmental Engineering, University of Alberta, 7-245 Donadeo-ICE, University of Alberta, 9203 116 St NW, Edmonton T6G 1R1, Canada. Electronic address:

Traumatic injury and idiopathic avascular necrosis of the talus bone can result in osteochondral lesions of the talus leading to pain, motion loss, and disability. Treatment with osteochondral allografting currently requires the donor talus to be size matched to the recipient talus to ensure precise fits. Eliminating or reducing the need for size matching would lessen costs and the delay between diagnosis and treatment. Read More

Compressive peroneal neuropathy by an intraneural ganglion cyst combined with L5 radiculopathy: A case report.

Medicine (Baltimore) 2019 Nov;98(44):e17865

Department of Physical Medicine and Rehabilitation, Haeundae Paik Hospital, Inje University College of Medicine, Busan, Republic of Korea.

Rationale: Most cases of foot drop are known to result from lower motor neuron pathologies, particularly lumbar radiculopathy and peripheral neuropathy, including common peroneal neuropathy. To improve the prognosis of foot drop, it is important to quickly and accurately diagnose the etiology and provide appropriate treatment.

Patient Concerns: A 65-year-old female patient with a history of L4-5 intervertebral disc herniation presented with right foot drop that had developed 1 month previously. Read More
