Cuneiform writing, an old art style, allows us to see into the past. Aside from Egyptian hieroglyphs, the cuneiform script is one of the oldest writing systems. It emerged in the second half of the fourth millennium BC. Most people believe that the Sumerians originally created it in southern Mesopotamia. Many historians place Hebrew\'s origins in antiquity. For example, we used the same approach to decipher the cuneiform languages; after learning how to decipher one old language, we would visit an archaeologist to learn how to decipher any other ancient language. We propose a deep-learning-based sign detector method to speed up this procedure to identify and group cuneiform tablet images according to Hebrew letter content. The Hebrew alphabet is notoriously difficult and costly to gather the training data needed for deep learning, which entails enclosing Hebrew characters in boxes. We solve this problem by using pre-existing transliterations and a sign-by-sign representation of the tablet\'s content in Latin characters. We recommend one of the supervised approaches because these do not include sign localization: We Find the transliteration signs in the tablet photographs by comparing them to their corresponding transliterations. Then, retrain the sign detector using these localized signs instead of utilizing annotations. Afterward, a more effective sign detector enhances the alignment quality. Consequently, this research aims to use the Yolov8 object identification pretraining model to identify Hebrew characters and categorize the cuneiform tablets. Images illustrating Hebrew passages have been culled from a Hebrew-language book. This book is known as the Old Testament, and it was organized into around 500 illustrations to aid in reading and pronouncing the characters. Another ancient document was recently discovered in Iraq, dating back to 500. It reached over a thousand photos after pre-processing and augmentation. The cuneiform digital library initiative (CDLI) website and the Iraqi Museum have compiled photographs of cuneiform tablets, with over a thousand photos available in each language.

UNASSIGNED: Osteochondroma is a benign skeletal neoplasm presenting with the proliferation of bony tissue. Osteochondroma of the foot is uncommon, and that of the cuneiform is an extremely rare entity.
UNASSIGNED: We present the case of a 22-year-old woman with osteochondroma of the left medial cuneiform who was having pain in the first ray of the left foot.
UNASSIGNED: Most cases of osteochondromas are nontender and painless masses with a benign asymptomatic course; however, progression to inflammation and neurovascular complications may cause considerable morbidity. The majority of cases are treated conservatively, while some severe cases require surgical management.
UNASSIGNED: Operative treatment of osteochondroma with excision of the mass remains a safe and successful alternative to conservative management whenever required.

UNASSIGNED: To use the computed tomography (CT) attenuation of the foot and ankle bones for opportunistic screening for osteoporosis.
UNASSIGNED: Retrospective study of 163 consecutive patients from a tertiary care academic center who underwent CT scans of the foot or ankle and dual-energy X-ray absorptiometry (DXA) within 1 year of each other. Volumetric segmentation of each bone of the foot and ankle was done in 3D Slicer to obtain the mean CT attenuation. Pearson\'s correlations were used to correlate the CT attenuations with each other and with DXA measurements. Support vector machines (SVM) with various kernels and principal components analysis (PCA) were used to predict osteoporosis and osteopenia/osteoporosis in training/validation and test datasets.
UNASSIGNED: CT attenuation measurements at the talus, calcaneus, navicular, cuboid, and cuneiforms were correlated with each other and positively correlated with BMD T-scores at the L1-4 lumbar spine, hip, and femoral neck; however, there was no significant correlation with the L1-4 trabecular bone scores. A CT attenuation threshold of 143.2 Hounsfield units (HU) of the calcaneus was best for detection of osteoporosis in the training/validation dataset. SVMs with radial basis function (RBF) kernels were significantly better than the PCA model and the calcaneus for predicting osteoporosis in the test dataset.
UNASSIGNED: Opportunistic screening for osteoporosis is possible using the CT attenuation of the foot and ankle bones. SVMs with RBF using all bones is more accurate than the CT attenuation of the calcaneus.

The mesencephalic locomotor region (MLR) serves as an interface between higher-order motor systems and lower motor neurons. The excitatory module of the MLR is composed of the pedunculopontine nucleus (PPN) and the cuneiform nucleus (CnF), and their activation has been proposed to elicit different modalities of movement. However, how the differences in connectivity and physiological properties explain their contributions to motor activity is not well known. Here we report that CnF glutamatergic neurons are more electrophysiologically homogeneous than PPN neurons and have mostly short-range connectivity, whereas PPN glutamatergic neurons are heterogeneous and maintain long-range connections, most notably with the basal ganglia. Optogenetic activation of CnF neurons produces short-lasting muscle activation, driving involuntary motor activity. In contrast, PPN neuron activation produces long-lasting increases in muscle tone that reduce motor activity and disrupt gait. Our results highlight biophysical and functional attributes among MLR neurons that support their differential contribution to motor behavior.

BACKGROUND: Diabetes mellitus (DM) with peripheral neuropathy (PN) results in foot deformity increasing ulceration, joint dislocation, and amputation risk. This study describes the frequency and severity of foot and ankle musculoskeletal abnormalities and their relationship to radiographic alignment in people with DMPN with (DMPN + MCD) and without (DMPN - MCD) medial column deformity (MCD) compared to age- and body mass index-matched controls without DMPN or MDC.
METHODS: DMPN + MCD (n = 11), DMPN - MCD (n = 12), and controls (n = 12) were studied. A radiologist scored foot and ankle magnetic resonance images (MRI) for abnormalities in tendons/fascia, ligaments, muscles, joints, and bones. Higher scores represent greater abnormalities. Foot alignment was measured from lateral weightbearing radiographs. Frequency of abnormalities between groups and relationships between abnormalities and foot alignment in the combined group (n = 35) were examined.
RESULTS: DMPN + MCD had higher total muscle, joint, and bone scores compared to controls and higher total joint scores than DMPN - MCD. DMPN - MCD had higher total muscle scores than controls. DMPN + MCD higher bone and joint scores were driven by increased frequency of osteophytes, cartilage damage, focal bone marrow edema, new bone formation, and subchondral cysts. Significant correlations included cuboid height and total bone and joint scores (ρ = -0.37 and ρ = -0.40, respectively) and talar declination angle and total joint score (ρ = 0.38).
CONCLUSIONS: High contrast resolution MRI allowed identification of structural lesions of the foot affecting the cartilage surfaces, bone marrow, and soft tissue supports in patients with DMPN + MCD. As expected, the presence of bone and joint lesions on MRI were strongly associated with DMPN + MCD; surprisingly, although the sample is small, lesions of the soft tissue supports were not associated with MCD. While MRI is not done routinely to investigate MCD, opportunistic use of the information from MRI done for the common clinical indications may allow early identification of the structural lesions associated with MCD and facilitate early, aggressive therapy.
METHODS: III.

Activation of the defence reaction inhibits the baroreflex response via the intermediate rostro-ventromedial medulla (B3 raphé) and nucleus tractus solitarius (NTS). Our aim was to determine whether and how baroreflex inhibition, induced by the disinhibition of the rostral cuneiform nucleus (part of the defence pathway), involves 5-HT neurons in B3 and 5-HT3 receptors in the NTS.
We performed immunohistochemistry and anatomical experiments to determine whether raphé 5-HT cells expressing Fos were directly targeted by the rostral cuneiform nucleus. The effect of blocking raphé 5-HT neurotransmission and NTS 5-HT3 receptors on cuneiform-induced inhibition of the baroreflex cardiac response were also analysed.
Bicuculline, microinjected into the rostral cuneiform nucleus, induced an increase of double-labelled Fos-5-HT-IR cells in both the lateral paragigantocellular nucleus (LPGi) and raphé magnus. The anterograde tracer Phaseolus vulgaris leucoaggutinin injected into the rostral cuneiform nucleus revealed a dense projection to the LPGi but not raphé magnus. Cuneiform-induced baroreflex inhibition was prevented by B3 injection of 8-OH-DPAT, a selective 5-HT1A receptor agonist. Cuneiform disinhibition also failed to inhibit the baroreflex bradycardia after NTS microinjection of the 5-HT3 receptor antagonist granisetron and in 5-HT3 receptor knockout mice.
The rostral cuneiform nucleus participates in the defence inhibition of the baroreflex bradycardia via direct activation of the LPGi and via a projection to the raphé magnus to activate NTS 5-HT3 receptors and inhibit second-order baroreflex neurons. These data bring new insights in primary and secondary mechanisms involved in vital baroreflex prevention during stress.

UNASSIGNED: The purpose of this study was to evaluate clinical and radiological outcomes at skeletal maturity after a calcaneo-cuboid-cuneiform osteotomy (triple C osteotomy) for symptomatic flatfoot deformity compared with healthy young adult controls.
UNASSIGNED: Nineteen patients (30 feet) who undergone a triple C osteotomy for idiopathic symptomatic flatfeet from July 2006 to April 2013 were compared with 19 controls (38 feet). Radiographic measurements at preoperative examination, 1-year postoperative follow-up, and follow-up at skeletal maturity were evaluated. Functional outcomes were assessed by using the validated visual analog scale foot and ankle (VAS-FA) and the modified American Orthopaedic Foot and Ankle Surgery (AOFAS) score.
UNASSIGNED: In the triple C osteotomy group, 11 of 12 radiographic measurements were significantly improved at 1 year postoperatively and the last follow-up (p < 0.001). There was no recurrence at skeletal maturity (p > 0.05). There were no significant differences in nine of 12 radiographic measurements between the triple C osteotomy group at maturity and the control group (p > 0.05). Average VAS-FA and AOFAS scores were significantly improved at the time of skeletal maturity (p < 0.001).
UNASSIGNED: Surgical correction of symptomatic flatfoot deformity in childhood resulted in favorable outcomes after the triple C osteotomy. Deformity correction was also maintained during follow-up at skeletal maturity.

UNASSIGNED: Hypermobility within the first tarsometatarsal (TMT) joint is a predisposing factor for hallux valgus. The purpose of this study was to assess whether the shape and angulation of the first TMT joint are affected by the positioning of the foot in radiographs.
UNASSIGNED: Ten adult above-knee fresh-frozen cadaveric specimens were placed into a radiolucent apparatus that allowed controlled angulation of each foot at 0, 5, 10, 15, and 20 degrees in dorsiflexion, plantarflexion, inversion, and eversion. For each specimen, the first TMT joint angle (1TMTJA), shape of the distal articular surface of the medial cuneiform (flat or curved), and image quality of the first TMT joint were measured.
UNASSIGNED: The mean value for 1TMTJA was 22.9 degrees (95% confidence interval [CI] 21.9-24). Individual anatomical variations of the specimens as well as the different angulations due to foot positioning significantly influenced the 1TMTJA (both P < .001). Joints that were found to have a flat configuration showed significantly increased 1TMTJA on average when compared to the ones with curved articular surface, 25.9 (95% CI 24.4-27.4) and 20.8 degrees (95% CI 19.5-22.0) (P < .001), respectively. Image quality for visualization of the first TMT joint was progressively better for increased angles of dorsiflexion and inversion.
UNASSIGNED: The shape and angulation of the first TMT joint on radiographic evaluation are affected by the positioning of the foot.
UNASSIGNED: Clinical usefulness of these radiographic characteristics is limited and should not influence operative planning in patients with possible instability of the first TMT joint.

Intercuneiform arthrodesis is often required for various midfoot pathologies; however, intercuneiform screw insertion is not easy due to the complicated anatomical structure of cuneiforms. This study aimed to determine the advisable screw entry point and direction using intraoperatively detectable landmarks. The computed tomography (CT) scan data of feet were reformatted using OsiriX software multiplanar reconstruction. First, based on the data of 10 CT scans of normal feet, we determined the advisable screw entry point at the upper one-third in the dorsoplantar direction and center in the anteroposterior direction on the medial aspect of the medial cuneiform and insertion direction toward the outermost point of the base of the fifth metatarsal in the axial plane and parallel to the plantar surface in the coronal plane. Second, we examined the accuracy of these newly designed guideposts in the simulation using other CT scan data of the other 27 normal feet and 12 flat feet. The simulated screw trajectory penetrated the mid three-fifths of all three cuneiforms in 97% of the normal feet and 92% of the flat feet with no cases of cortical wall violation. Levels of Evidence: Level V: Expert opinion.

BACKGROUND: Multitrauma patients suffering hindfoot fractures, including calcaneal and talar fractures, often result in poor outcomes. However, less is known about the outcomes following midfoot fracture in the mutitrauma population. This study aims to describe the epidemiology of midfoot fractures in multitrauma patients and to compare the outcomes of midfoot and hindfoot fractures in this population.
METHODS: Data about multitrauma patients (Injury Severity Score >12) sustaining a unilateral midfoot or hindfoot fracture were obtained from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) and from retrospective review of medical records at a major trauma centre. Further outcome data were obtained via a survey using the American Academy of Orthopedic Surgeons Foot and Ankle Score (AAOS FAS) and the 12-item Short Form Health Survey (SF-12).
RESULTS: 122 multitrauma patients were included; 81 with hindfoot fractures and 41 with midfoot fractures. The median ISS (IQR) was 22 (17-29) and 27 (17-24) for the hindfoot and midfoot groups, respectively (p = 0.23). Hindfoot and midfoot fractures were commonly associated with intracranial injuries (80.3%), spine injuries (60.7%), ipsilateral lower extremity injuries (24.6%) and pelvic injuries (16.4%). The mean (SD) time to follow up was 4.5 (±2.7) years. There were no differences in mean SF-12 physical (37.97 vs 35.22, p = 0.33) or mental (46.90 vs 46.67, p = 0.94) component summary scores between the groups. There were no differences in mean AAOS FAS standard scores (69.3 vs 69.1, p = 0.97) or shoe comfort scores (median 40 vs 40 p = 0.18) between the groups.
CONCLUSIONS: Functional outcomes in multitrauma patients with midfoot or hindfoot fractures were comparable. These findings suggest that midfoot fractures should be treated with the same degree of due diligence as hindfoot fractures in the multitrauma patient.
