The 3D anatomical complexity of the foot and ankle importance weight-bearing in diagnosis have required combination conventional radiographs medical CT.Conventional plain (XR) demonstrated substantial limitations such as perspective, rotational fan distortion, well poor reproducibility radiographic installations. Conventional CT produces high levels radiation exposure does not offer capabilities.The literature investigating biometrics based on 2D XR has inherent due to technology itself...
Background: Hindfoot alignment on 2D radiographs can present anatomical and operator-related bias. In this study, software designed for weightbearing computed tomography (WBCT) was used to calculate a new 3D biometric tool: the Foot Ankle Offset (FAO). We described distribution of FAO in series data sets from clinically normal, varus, valgus cases, hypothesizing that values would be significantly different 3 groups. Methods: retrospective cohort 135 (57 38 40 valgus) WBCT (PedCAT; CurveBeam...
Background: Weightbearing computed tomography (WBCT) is a useful tool for the assessment of hindfoot alignment (HA). Foot ankle offset (FAO) recently introduced parameter, determined from WBCT images using semiautomatic software. The aim this study was to determine clinical relevance and reproducibility FAO evaluation HA. Methods: A prospective comparative performed on consecutive patients requiring bilateral between September 2017 April 2018. Based HA, were divided into 3 groups: (1) normal...
Progressive peritalar subluxation (PTS) is part of adult acquired flatfoot deformity (AAFD). We investigated the use middle facet as an indicator PTS using standing, weight-bearing computed tomography (CT) images. hypothesized that CT would be accurate method measuring increased ("uncoverage") and incongruence middle-facet among patients with AAFD.We included 30 stage-II AAFD (20 female 10 male; mean age, 57.4 years [range, 24 to 78 years]) matched controls 51.8 19 81 who underwent CT. Two...
Weightbearing CT (WBCT) has been proven to more precisely measure bone position than conventional weightbearing radiographic series (R) and (CT). The purpose of this study was assess the benefit using WBCT instead R and/or as standard imaging modality, evaluating image acquisition time, radiation dose, cost-effectiveness. All patients who obtained a part care from July 1, 2013 until March 15, 2019 were included in study. Image time (T), dose (RD) per patient, cost-effectiveness analyzed...
Background: Semiautomatic 3-dimensional (3D) biometric weightbearing computed tomography (WBCT) tools have been shown to adequately demonstrate the relationship between center of ankle joint and tripod foot. The measurement foot offset (FAO) represents an optimized biomechanical assessment alignment. objective this study was evaluate correlation FAO traditional adult acquired flatfoot deformity (AAFD) markers, measured in different planes. We hypothesized that would significantly correlate...
Background: Progressive collapsing foot deformity (PCFD), formerly termed adult-acquired flatfoot deformity, is a complex 3-dimensional (3D) of the characterized by peritalar subluxation (PTS). PTS typically measured at posterior facet, but recent studies have called this into question. The objective study was to use 3D distance mapping (DM) from weightbearing computed tomography (WBCT) assess in patients with PCFD and controls. We hypothesized that DMs would identify middle facet as...
Background: Varus hindfoot deformity may increase the risk of chronic lateral ankle instability (CLAI). Our aim was to analyze alignment (HFA) in patients with CLAI using weight-bearing cone beam computed tomography (WBCT) assess this risk. Methods: This retrospective, comparative analysis carried out an existing WBCT database (Talas, CurveBeam LLC), including data sets for 370 consecutive feet (189 patients) obtained between July 2016 and October 2018 at a single institution. The software...
Background: We investigated the association between hindfoot residual malalignment assessed on weightbearing computed tomography (WBCT) images and development of periprosthetic cysts (PPCs) after total ankle replacement (TAR). hypothesized that PPCs would be found predominantly medially in varus configuration laterally valgus configuration. Methods: Cases primary TAR with available WBCT imaging were included this retrospective study. The location PPC was marked following volumes calculated:...
Background: Weightbearing cone beam computed tomography (WBCT) has been gaining traction as a useful imaging modality in the diagnosis and follow-up of foot ankle musculoskeletal pathologies due to ability perform quick, low-dose, 3-dimensional (3D) scans. However, resulting wealth 3D data renders daily clinical use time-consuming. The aim this study was evaluate new artificial intelligence (AI)–based automatic measurement for M1-M2 intermetatarsal angle (IMA) hallux valgus (HV). We...
The Distal Metatarsal Articular Angle (DMAA) was previously described as an increase in valgus deformity of the distal articular surface first metatarsal (M1) hallux (HV). Several studies have reported poor reliability this measurement. Some authors even called into question its existence and consider it to be consequence M1 pronation resulting projection round-shaped lateral edge head.Our study aimed compare DMAA HV control populations, before after computer correction plantarflexion with a...
The early effects of progressive collapsing foot deformity (PCFD) on the ankle and syndesmotic joints have not been three-dimensionally quantified. This case-control study focused using weight bearing CT (WBCT) distance (DM) coverage maps (CM) volumetric measurements as 3D radiological markers to objectively characterize PCFD joints. Seventeen consecutive patients with symptomatic stage I flexible 20 matched controls that underwent foot/ankle WBCT were included. Three-dimensional DM CM...
Background: A customized pedography sensor (Pliance; Novel, Munich, Germany) was inserted into a pedCAT (Curvebeam, Warrington, PA). The aim of this study to analyze the relative position anatomical foot center (FC) and pedographic gravity (COG). hypothesis that FC should be good predictor mediolateral COG but not longitudinal since hindfoot anatomy allows free anteroposterior movement limited movement. Methods: In 90 patients (180 feet), scan with simultaneous full weightbearing in standing...
Weightbearing cone beam computed tomography (WB CBCT) allows detailed 3-dimensional imaging of the foot and ankle in a weightbearing state provides improved accuracy reliability alignment measures, especially when compared with conventional radiographic views.To describe National Basketball Association (NBA) players different symptomatic injuries using WB CBCT to determine if any predominant morphotype would be identified.Cross-sectional study; Level evidence, 3.A total 45 active NBA (mean...
Background: We previously reported an increase in pronation of the first metatarsal (M1) head relative to ground hallux valgus (HV) patients compared controls. Still, origin and location this hyperpronation along medial column is unknown. Recent studies showed that presence progressive collapsing foot deformities (PCFDs), which a condition frequently associated with HV, can strongly influence coronal plane alignment. The objective study was assess rotation bones HV feet, feet radiologic...
Background: Proximal fifth metatarsal fractures are common injuries that classified into 3 zones according to their anatomical localization. While zone 1 and 2 typically traumatic, may be linked foot alignment abnormalities, such as hindfoot varus metatarsus adductus. The aim of the study was explore association between different fracture zones, well relationship traumatic atraumatic origin alignment. Methods: We conducted a retrospective cohort patients with proximal who had received...
