J Orthop Res 2018 Dec 11. Epub 2018 Dec 11.

RR&D Center for Limb Loss and MoBility, VA Puget Sound, Seattle, WA.

Foot type has been associated with pain, injury, and altered gait mechanics. Morphological variations in foot bones due to foot type variation may impact surgical and therapeutic treatments. The purpose of this study was to utilize principal component analysis (PCA) to determine how morphology of the hind- and midfoot bones differs among foot types and sex. Read More

Cranio-caudal and medio-lateral navicular translation are representative surrogate measures of foot function in asymptomatic adults during walking.

PLoS One 2018 5;13(12):e0208175. Epub 2018 Dec 5.

Bern University of Applied Sciences, Department of Health Professions, Division of Physiotherapy, Bern, Switzerland.

Introduction: The translation of the navicular bone is thought to be a representative surrogate measure to assess foot pronation and hence foot function; however, it is not known how it is related to multi-segment foot kinematics.

Methods: Cranio-caudal (NCC) and medio-lateral (NML) navicular translation and multi-segment foot kinematics from the Oxford Foot Model (OFM) were simultaneously assessed during the stance phase of walking in 20 healthy adults. Relationships to forefoot to hindfoot (FFtoHF), hindfoot to tibia (HFtoTBA) and global hindfoot (HFL) motion were explored by cross-correlations at zero phase shift. Read More

Effects of selective strengthening of tibialis posterior and stretching of iliopsoas on navicular drop, dynamic balance, and lower limb muscle activity in pronated feet: A randomized clinical trial.

Phys Sportsmed 2018 Dec 5:1-11. Epub 2018 Dec 5.

b Rehabilitation Research Chair, College of Applied Medical Sciences , King Saud University , Riyadh , Saudi Arabia.

Magnetic resonance and radiographic imaging of a case of bilateral bipartite navicular bones in a horse.

Aust Vet J 2018 Nov;96(11):464-469

School of Veterinary Science, University of Queensland, Gatton, Queensland, Australia.

Case Report: We describe the radiographic and magnetic resonance imaging findings associated with a case of bilateral forelimb bipartite navicular disease in a 7-year-old Warmblood gelding used for eventing. In addition to the radiographically evident partitioned navicular bones, magnetic resonance imaging (MRI) also detected other concurrent abnormalities occurring within the foot that have not been described before in other cases of navicular bone partition. MRI not only revealed soft tissue lesions of the podotrochlear apparatus, but also allowed for more detailed characterisation of the recently diagnosed osseous navicular bone pathology. Read More

Mice harboring an MCTO mutation exhibit renal failure resembling nephropathy in human patients.

Exp Anim 2018 Oct 26. Epub 2018 Oct 26.

Department of Anatomy and Embryology, Faculty of Medicine, University of Tsukuba.

Multicentric carpotarsal osteolysis (MCTO) is a condition involving progressive osteolysis of the carpal and tarsal bones that is associated with glomerular sclerosis and renal failure (MCTO nephropathy). Previous work identified an autosomal dominant missense mutation in the transactivation domain of the transcription factor MAFB as the cause of MCTO. Several methods are currently used for MCTO nephropathy treatment, but these methods are invasive and lead to severe side effects, limiting their use. Read More

Accessory navicular syndrome as a cause of foot pain during stroke rehabilitation.

Departments of Geriatric Medicine, Galway University Hospitals, Galway, Ireland.

Although usually asymptomatic, an accessory navicular bone can lead to medial foot pain, especially in younger people engaged in high impact sports. In many such cases, the tendon of posterior tibialis (which inverts and plantarflexes the foot) inserts onto the accessory bone resulting in greater strain on the tendon. In the present case, pain due to an accessory navicular bone first developed during stroke rehabilitation in a 69-year-old man. Read More

Extensile lateral versus sinus tarsi approach for displaced, intra-articular calcaneal fractures: a meta-analysis.

J Orthop Surg Res 2018 Sep 24;13(1):243. Epub 2018 Sep 24.

Orthopaedics Department, Westmead Hospital, Corner of Hawkesbury and Darcy Roads, Westmead, Sydney, Australia.

Background: Operative management of displaced, intra-articular calcaneal fractures is associated with improved functional outcomes but associated with frequent complications due to poor soft tissue healing. The use of a minimally invasive sinus tarsi approach to the fixation of these fractures may be associated with a lower rate of complications and therefore provide superior outcomes without the associated morbidity of operative intervention.

Methods: We reviewed four prospective and seven retrospective trials that compared the outcomes from the operative fixation of displaced intra-articular calcaneal fractures via either an extensile lateral approach or minimally invasive fixation via a sinus tarsi approach. Read More

Transepiphyseal (Type VII) Ankle Fracture Versus Os Subfibulare in Pediatric Ankle Injuries.

Background: Pediatric ankle injuries are common, giving rise to ∼17% of all physeal injuries. An os subfibulare in a child with an ankle sprain may be confused with a type VII transepiphyseal fracture. Here, we evaluate the clinical and radiographic features of type VII transepiphyseal fractures to those of os subfibulare presenting with acute ankle trauma with the hypothesis that radiographs are necessary for final diagnosis and neither clinical history nor examination would be diagnostic.

Objectives of this retrospective observational study were to describe low-field magnetic resonance imaging (MRI) findings and long-term outcome for a group of horses with this combination of clinical problems. Horses were included if low-field standing MRI of the foot was performed following puncture wounds, injury of the deep digital flexor tendon was diagnosed, and sepsis was confirmed to be absent in all adjacent synovial structures (distal interphalangeal joint, navicular bursa, and digital flexor tendon sheath).
