Locomotion is a fundamental motor function common to the animal kingdom. It is implemented episodically and adapted to behavioural needs, including exploration, which requires slow locomotion, and escape behaviour, which necessitates faster speeds. The control of these functions originates in brainstem structures, although the neuronal substrate(s) that support them have not yet been elucidated. Here we show in mice that speed and gait selection are controlled by glutamatergic excitatory neurons (GlutNs) segregated in two distinct midbrain nuclei: the cuneiform nucleus (CnF) and the pedunculopontine nucleus (PPN)...

Background The involvement of the central nervous system in primary Sjögren syndrome (pSS) remains controversial. Functional magnetic resonance imaging (fMRI) is a relatively new method that can be applied to investigate the heterogeneity of central nervous system (CNS) involvement in pSS patients through regional homogeneity (ReHo) analysis. Purpose To collect data from pSS patients and healthy controls, and use ReHo analysis to elucidate the neurobiological mechanism of CNS involvement in pSS. Material and Methods Fourteen clinically diagnosed pSS patients and 14 age- and gender-matched healthy controls underwent resting-state fMRI...

Introduction: Spindle cell hemangioma (SCH) of the bone (midfoot) is a rare disease, but it can cause symptomatic pain and invade surrounding tissues lead to limb deformities and functional loss. Case Report: We report the case of a 35-year-old woman who experienced a firm mass over the left midfoot for 5 years causing pain and numbness in the foot. Radiographs showed a geographic osteolytic lesion involving calcification of the base of the 2nd and 3rd metatarsals, cuneiforms bones and surrounding soft tissue...

We report a case of a 23-year-old woman who sustained a stress fracture to the medial cuneiform. Isolated medial cuneiform fractures are extremely rare with less than 10 cases reported in the literature. The patient initially presented to an urgent care facility complaining of right midfoot pain that occurred while running. Radiographs obtained at the time showed no acute abnormality and the patient was told to resume normal activities. Several weeks later, she presented to urgent care again after exercising, this time unable to bear weight and with swelling and ecchymoses of the right foot...

Background: The presence of nitric oxide (NO) in the cuneiform nucleus (CnF) has been previously shown. In this study, NG-nitro-L-arginine methyl ester (L-NAME) (an inhibitor of NO synthase), L-arginine (L-Arg) (a precursor of NO), and sodium nitroprusside (SNP) (a donor of NO) were microinjected into the CnF and cardiovascular responses were investigated. Methods: Seventy male rats were divided into 7 groups (n=10 each): 1) saline, 2 and 3) L-NAME (30 and 90 nmol), 4 and 5) L-Arg (20 and 60 nmol), and 6 and 7) SNP (9 and 27 nmol)...

A new monozoic cestode, Parabreviscolex niepini n. gen. and n. sp. (Cestoda: Caryophyllidea), is described from the type-host Schizopygopsis younghusbandi Regan, 1905 (Cyprinidae: Schizothoracinae) and Schizothorax waltoni Regan, 1905 (Cyprinidae: Schizothoracinae) in the Yarlung Tsangpo River, the upper tributary of the Brahmaputra River on the Tibetan Plateau. The new genus is placed in the Capingentidae because the vitellarium is situated partly in the medullary and cortical parenchyma, i.e., neither completely external nor internal to inner longitudinal muscles...

BACKGROUND: An association has been reported between hallux valgus and hypermobility of the first ray, but subluxation of the intercuneiform 1-2 joint was also suspected in some cases. However, dynamics of the intercuneiform 1-2 joint has seldom been investigated. This study used weightbearing computed tomography (CT) and a 3-dimensional (3D) analysis system to evaluate displacement of the intercuneiform 1-2 joint, intercuneiform 2-3 joint, and second cuneonavicular joint due to weightbearing in hallux valgus and normal feet...

An isolated medial cuneiform fracture is a rarely encountered injury of the foot. We present a case of an isolated medial cuneiform fracture in a patient after sustaining a fall from a 15-foot height. Treatment consisted of primary arthrodesis of the first tarsometatarsal joint due to a high degree of comminution and intra-articular pain. When radiographs are inconclusive and the index of suspicion remains high for a lesser tarsus fracture, computed tomography is recommended. In patients with minimal displacement, conservative treatment is usually successful in achieving osseous fusion...

REVIEW
J Hamel
Cavovarus deformities in children and adolescents require sound considerations concerning the timing for corrective surgery. Progression can be recognized best by repeated pedographic examination with evaluation of the typical features of cavovarus deformity. Surgical correction consists of a combination of soft tissue release, bony realignment, and restoration of muscle balance. In most cases plantar or medioplantar soft tissue release should be considered, whereas calf muscle lengthening is rarely indicated...

Understanding neuroanatomical sympathetic circuitry and neuronal connections from the caudal pedunculopontine tegmental nucleus to skeletal muscle is important to the study of possible mechanisms of pedunculopontine tegmental nucleus (PPTg) and cuneiform nucleus (CnF) that are involved in the regulation of skeletal muscle activity of the sympathetic pathway. The aim of this study was to use virus PRV-614 to trace the melanocortin-sympathetic neural pathways from PPTg and CnF to a hindlimb muscle (gastrocnemius) in spinally transected MC4R-GFP transgenic mice...

The goal of this study was to characterize the function of microRNA-27a-3p (miR-27a-3p) in polycystic ovary syndrome (PCOS). MiR-27a-3p expression was analyzed in excised granulosa cells (GCs) from 21 PCOS and 12 normal patients undergoing IVF cycle treatments, and in 17 non-treated cuneiform ovarian resection PCOS samples and 13 control ovarian samples-from non-PCOS patients. We found that the expression of miR-27a-3p was significantly increased in both excised GCs and the ovaries of PCOS patients compared to the controls...

BACKGROUND: The 3-dimensional nature of adult acquired flatfoot deformity can be challenging to characterize using radiographs. We tested the hypothesis that measurements on weight-bearing (WB) cone-beam computed tomography (CT) images were more useful for demonstrating the severity of the deformity than non-weight-bearing (NWB) measurements. METHODS: We prospectively enrolled 12 men and 8 women (mean age, 52 years; range, 20 to 88 years) with flexible adult acquired flatfoot deformity...

PURPOSE: The aetiology of hallux valgus (HV) is multifactorial in nature. The first metatarsocuneiform joint obliquity is a well-known factor in the development of the deformity. The purpose of this study is to assess the correlation of different medial cuneiform radiological measures on the severity of HV. METHODS: Full weight-bearing anteroposterior views of 152 feet with different clinical severity are divided into four groups: without deformity and with mild, moderate and severe deformities...

AIMS: After the initial correction of congenital talipes equinovarus (CTEV) using the Ponseti method, a subsequent dynamic deformity is often managed by transfer of the tendon of tibialis anterior (TATT) to the lateral cuneiform. Many surgeons believe the lateral cuneiform should be ossified before surgery is undertaken. This study quantifies the ossification process of the lateral cuneiform in children with CTEV between one and three years of age. PATIENTS AND METHODS: The length, width and height of the lateral cuneiform were measured in 43 consecutive patients with unilateral CTEV who had been treated using the Ponseti method...

REVIEW
Markus Walther
BACKGROUND: The most common cause of degeneration of the posterior tibial tendon is a congenital valgus deformity of the calcaneus. Other associated pathologies are forefoot supination, forefoot abduction and shortening of the gastrocnemius muscle. DIAGNOSTICS: Loaded x‑rays of the foot in three planes as well as the hindfoot alignment view enable evaluation of the axis of the foot under static loading conditions. The posterior tibial tendon can be imaged with ultrasound and magnetic resonance imaging (MRI)...

BACKGROUND: A midfoot sprain can be easily missed because of minimal findings on initial radiographs, which are almost universally nonweightbearing. We investigated preoperative nonweightbearing plain radiographic images in patients who were found to have unstable subtle Lisfranc injuries. METHODS: We retrospectively reviewed 51 patients who were operated on between February 2004 and March 2015. Abnormal preoperative radiographic findings and intraoperative instability were compared...

Troy J Boffeli, Katherine R Schnell
The Cotton osteotomy or opening wedge medial cuneiform osteotomy is a useful adjunctive flatfoot reconstructive procedure that is commonly performed; however, the outcomes are rarely reported owing to the adjunctive nature of the procedure. The Cotton procedure is relatively quick to perform and effectively corrects forefoot varus deformity after rearfoot fusion or osteotomy to achieve a rectus forefoot to rearfoot relationship. Proper patient selection is critical because the preoperative findings of medial column joint instability, concomitant hallux valgus deformity, or degenerative joint disease of the medial column might be better treated by arthrodesis of the naviculocuneiform or first tarsometatarsal joints...

This study aimed to analyze precisely the dimensions, shapes, and variations of the insertional footprints of the tibialis anterior tendon (TAT) at the medial cuneiform (MC) and first metatarsal (MT1) base. Forty-one formalin-fixed human cadaveric specimens were dissected. After preparation of the TAT footprint, standardized photographs were made and the following parameters were evaluated: the footprint length, width, area of insertion, dorsoplantar location, shape, and additional tendon slips. Twenty feet (48...
