Hallux valgus (HV) is a common deformity of the great toe affecting >23% of adults in the United States. The severity of the deformity is traditionally analyzed using radiographs to determine measurements such as the HV and intermetatarsal angles. We sought to determine the relationship between the radiographic and magnetic resonance imaging (MRI) measurements because this is not yet known. Two of us analyzed a series of 56 consecutive patients who had had radiographs and MRI performed on the same foot between April 27, 2015 and March 9, 2016 and who satisfied all other inclusion and exclusion criteria (age 18 to 100 years, no history of recent foot trauma, and no metal hardware in the foot)...

BACKGROUND: Rotational malalignment after intramedullary nailing of tibial shaft fractures is not uncommon. In-toeing and out-toeing conditions in children are often the reason for orthopedic and traumatological medical consultation. OBJECTIVE: Evaluation of diagnostic modalities and therapeutic options for rotational malalignment in relationship to the patient's age. Surgical indications and efficacy of specific surgical techniques. MATERIAL AND METHODS: Systematic literature search in the German Institute for Medical Documentation and Information (DIMDI) and MEDLINE and evaluation of the currently published articles...

The effects of motor imagery on spinal reflexes such as the H-reflex are unclear. One reason for this is that the muscles that can be used to record spinal reflexes are limited to traditional evoking methods Recently, transcutaneous spinal cord stimulation has been used for inducing spinal reflexes from multiple muscles and we aimed to examine the effect of motor imagery on spinal reflexes from multiple muscles. Spinal reflexes evoked by transcutaneous spinal cord stimulation were recorded from six muscles from lower limbs during motor imagery of right wrist extension and ankle plantarflexion with maximum isometric contraction...

A 30-year-old female presented to the rheumatology outpatient clinic of the Internal Medicine Department, Ain Shams University Hospital, Cairo, Egypt, complaining of a large right leg ulcer consistent with pyoderma gangrenosum. There was history of recurrent attacks of bleeding per rectum of one-year duration. During hospitalization she noticed blurring of vision in the left eye with diffuse blackish discoloration of the feet and toes, consistent with small-vessel vasculitis. Colonoscopy with biopsy and histopathology confirmed the diagnosis of inflammatory bowel disease-ulcerative colitis (IBD-UC)...

Digital sesamoids are found in the metapodial-phalangeal joints of most mammals and quadrupedal tetrapods, yet their functional significance is still unclear. During primate evolution, a slight decline in their frequency has been associated with brachiation in gibbons, followed by a quasi-complete absence in orangutans then a slight resurgence occurred in gorillas and chimpanzees. Simultaneously, forearm muscles showed a progressive division in hominoid evolution towards a more "individualistic" musculature yielding more mobility and independence to some fingers...

BACKGROUND: Osteoprotegerin plays a role in the development of several bone diseases. In addition, osteoprotegerin may contribute to the development of vascular disease. Little is known about the association between serum osteoprotegerin levels and the presence or severity of peripheral arterial disease (PAD). The aim of this study was to examine the association between serum osteoprotegerin levels and both the presence as well as the severity of lower extremity arterial disease in patients with type 2 diabetes (T2DM)...

Diabetes mellitus is a major health problem for older adults worldwide and could be associated with impaired ability to recover balance after postural disturbances. This study compared reactive balance control in three groups of adults, young (YA), healthy non-diabetes older (nonDM-OA) and diabetes older (DM-OA). Twenty participants in each group completed a series of vision, plantar cutaneous sensitivity, grip power and lower limb strength tests. In the reactive balance test, participants stood on a force platform and used the dominant hand to pull the handle of a cord that could be suddenly released to create an imbalancing force...

We describe an unusual case of blue toe syndrome as the primary and solitary manifestation of systemic sclerosis. The possible cause was long-term occupational exposure in construction work. Blue toe syndrome is a small vessel disease, characterised by the sudden development of painful, blue discolouration in one or more toes. The most common aetiology is atheroembolic disease; however, it can also appear in several conditions ranging from hypercoagulability disorders to underlying systemic diseases such as vasculitis or autoimmune diseases...

BACKGROUND: Knee adduction moment (KAM) is often used as a surrogate marker of knee contact force (KCF) during walking. Previous studies have reported potential benefits to reduce KAM in patients with knee osteoarthritis (OA) by foot progression angle adjustment. However, KAM is an external moment and it does not consider any muscle contribution to the joint loading, which should pose a greater influence in running than walking. RESEARCH QUESTION: This study used a computational model to compare KAM and KCF between runners with and without knee OA during running...

A 15-year-old boy was referred due to gynecomastia and short stature. He was overweight and showed the knuckle-dimple sign on the left hand, a short fourth toe on the left foot, and male external genitalia with a small phallus. His levels of estradiol and follicle-stimulating hormone were increased, and his testosterone concentration was normal. Other hormonal tests were within the normal range. Radiographs showed short fourth and fifth metacarpals and fourth metatarsal bones. The karyotype was reported as 46,X,+mar, and the marker chromosome was shown to originate from the Y chromosome, which was identified by fluorescence in situ hybridization...

BACKGROUND: Minimally invasive surgery has a shorter surgical time, and in this study we focus on minimally invasive distal metatarsal metaphyseal osteotomy (DMMO). The operation seems to be less complex but requires a high learning curve. We report on our first patients to underline the need for extensive training and great awareness for the risks in the early learning stages. METHODS: We evaluated 27 patients (mean age = 60.9 years) with a mean follow-up time of 7...

The primary objective of medical tattooing is to restore part of a patient's physical integrity. Moreover, the procedure seeks to assist in psychological recovery from the physical and/or psychological consequences of disease, surgery or trauma. The method described in this brief note marks a step forward in the field of such tattooing. The treatment simulates reconstruction of the nail bed, as the nails of the big toes had previously been removed through a surgical avulsion procedure. This treatment, agreed with the physician and performed by a tattooist with proven experience in medical tattooing, also involved the use of specific colour nuances that resulted in an extremely realistic outcome...

Whole-exome and targeted sequencing of 13 individuals from 10 unrelated families with overlapping clinical manifestations identified loss-of-function and missense variants in KIAA1109 allowing delineation of an autosomal-recessive multi-system syndrome, which we suggest to name Alkuraya-Kučinskas syndrome (MIM 617822). Shared phenotypic features representing the cardinal characteristics of this syndrome combine brain atrophy with clubfoot and arthrogryposis. Affected individuals present with cerebral parenchymal underdevelopment, ranging from major cerebral parenchymal thinning with lissencephalic aspect to moderate parenchymal rarefaction, severe to mild ventriculomegaly, cerebellar hypoplasia with brainstem dysgenesis, and cardiac and ophthalmologic anomalies, such as microphthalmia and cataract...
