Taylor spatial frame

Background The use of circular frames in correcting lower limb deformity is well-established and has evolved dramatically over the years. Three new frames have been introduced recently, and this study is set to compare them in terms of accuracy and efficiency in correcting a similar long bone deformity. These frames are the Taylor Spatial Frame (TSF; Smith & Nephew, London, United Kingdom), the Truelok Hexapod System (TL-HEX; Orthofix, Lewisville, Texas), and Orthex (OrthoPediatrics, Warsaw, Indiana). Methods This is a biomechanical study comparing the above three types of circular frames to correct similar deformities in Sawbones models...

Genu varum is a common finding in the pediatric population with a large differential, including but not limited to Blount's disease, rickets, and physiologic bowing of the legs. Here we report a case of a 12-year-old Caucasian male who presented for an atraumatic stress fracture of the fifth metatarsal after an athletic event. Further evaluation showed significant genu varum with a Q angle of 9 degrees and medial knee joint space narrowing. The patient was unable to undergo conservative management due to early completion of puberty with relatively premature skeletal maturity...

Despite success of the Ponseti method, a subset of patients with clubfeet experience residual deformity. Surgical release after unsuccessful serial casting can lead to residual clubfoot deformities, including a flat-top talus. We present a case of a 17-year-old boy with a dysmorphic ankle and a complete dorsal dislocation of the Chopart joint. Because of pain with activities and functional limitations, the patient underwent a staged correction of the dislocation. The deformity was corrected through a staged approach using a Taylor Spatial Frame, navicular excision, talocuneiform arthrodesis, and calcaneocuboid arthrodesis...

Obtaining alignment during end-stage knee osteoarthritis with extraarticular deformities has always been challenging. Therefore, we report a case of total knee arthroplasty, following the application of Taylor Spatial Frame to treat knee osteoarthritis with severe tibia extraarticular deformity due to a proximal tibia fracture injury for more than 50 years ago. First, proximal tibial opening wedge osteotomy was conducted below the patellar tendon insertion from the anterior to the posterior direction to correct the deformity in multiple planes gradually...

Background and Objectives : Tibial malunions are defined as tibial fractures that have healed in a clinically unacceptable position, resulting in deformity such as shortening, lengthening, abnormal rotation, or angulation. These deformities can have adverse effects on patients, such as pain and gait disturbance, as well as long term development of post-traumatic arthritis. This paper seeks to highlight some of the options for surgical management of malunions and detail the strategies and approaches used to manage these complicated cases...

Background: The Ilizarov method and fixator are clinically recognised for the treatment of fractures, limb salvage and deformity correction. There have been extensive studies determining the basic mechanism for fracture healing using this technique. It is generally accepted that circular frames optimise the mechanical environment by reducing shear strain across the fracture while maintaining axial micromotion so as to promote fracture healing. There have been several new hexapod-type frames introduced into the market over the past 20 years with little comparative research into their biomechanical properties and resultant effects on the fracture environment...

CASE: A 36-year-old woman with diabetic neuropathy presented with complete dorsal dislocation of the midfoot secondary to Charcot arthropathy. She was treated in a staged fashion with a Taylor spatial butt frame to distract and reduce the midfoot followed by percutaneous preparation of the tarsometatarsal (TMT) joints and fixator-assisted fusion. The arthrodesis healed successfully with maintenance of function at the 30-month follow-up. CONCLUSION: Staged treatment with a Taylor spatial frame can be used successfully to treat complete TMT dislocations in the setting of Charcot arthropathy...

Clinically, Taylor spatial frame (TSF) is usually used to correct femoral deformity. The first step in correction is to analyze skeletal deformities and measure the center of rotation of angulation (CORA). Since the above work needs to be done manually, the doctor's workload is heavy. Therefore, an automatic femoral deformity analysis system was proposed. Firstly, the Hough forest and constrained local models were trained on the femur image set. Then, the position and size of the femur in the X-ray image were detected by the trained Hough forest...

The aim of this study is to evaluate the course of the treatment and clinical and functional outcomes of femur lengthening in adolescents with congenital disorders by the application of different surgical methods. This retrospective study comprised 35 patients (39 procedures). A total of 11 patients underwent femur lengthening with the use of the intramedullary magnetic nail (IMN) Precise 2 (NuVasive, San Diego, CA, USA), 7 patients (11 procedures) with the use of the monolateral external distractor Modular Rail System (MRS) (Smith and Nephew, Memphis, TN, USA), and 17 with the use of the computer-assisted external fixator Taylor Spatial Frame (TSF) (Smith and Nephew, Memphis, TN, USA)...

Background: High tibial osteotomy (HTO) is used to treat medial degeneration of the osteoarthritis (OA) knee. However, shortcomings still exist in the current procedure, like unprecise creation, inability to correct knee rotation, and internal fixed failure. Here, we reported a novel procedure: patient-specific 3D-printed plates for opening wedge high tibial osteotomy (OWHTO) combined with Taylor spatial frame (TSF). The detailed technique was described, and the clinical outcomes were evaluated...

Aim and objective: Genu recurvatum is a rare deformity for which minimal literature exists. Non-operative management typically gives unsatisfactory results. This study aims to evaluate the treatment of genu recurvatum with a hexapod frame. Materials and methods: A single-center retrospective chart review of genu recurvatum cases treated with a hexapod fixator application was performed. Radiographic parameters included the following: leg length discrepancy (LLD), angle of recurvatum, angle of tilt of the tibial plateau, patellar height and anatomic proximal posterior tibial angle (aPPTA)...

Charcot arthropathy related foot and ankle deformities are a serious challenge. Surgical treatment of these deformities is now well established. Conventional surgical treatment includes extensive surgical exposure, excision of bone, acute correction and internal fixation, which is not always appropriate in presence of active ulceration, infection and poor bone quality. A minimally invasive approach to osteotomies and gradual correction of deformities using a circular frame are proving helpful in minimizing the complications...

3MC syndrome is a rare genetic disorder inherited through an autosomal recessive inheritance pattern caused by mutations in one of three genes: COLEC11 , COLEC10 , and MASP1 . High-arched brows, ptosis, blepharophimosis, hypertelorism, cleft lip, cleft palate, developmental delay, hearing loss, abdominal wall defect, and urogenital and skeletal abnormalities are all characteristics. In previous reports, involvement of knee flexion contracture was not known to be one of the 3MC syndrome symptoms. The prevalence of 3MC syndrome is still unknown, and there have only been a few reports...

OBJECTIVES: Functional impairment is a common complaint in patients with venous malformations. Equinus can occur when the venous malformation involves the lower limb, a challenging condition with only a few studies to guide treatment choices. This study was aimed to investigate the operative management of equinus associated with lower limb venous malformations. METHOD: Between August 2015 and September 2017, a total of 12 patients presented with equinus associated with lower limb venous malformations and underwent surgical correction...

BACKGROUND: Severe open tibia fractures are challenging to treat with a lack of published clear management strategies. Our aim was to provide an overview of the largest single-center experience in the literature, with minimum 1-year follow-up, of adult type 3 open tibial shaft fractures at Cambridge University Hospitals (a United Kingdom major trauma center). We sought to define patient characteristics and our main outcome measures were infection, union and re-fracture. AIM: To retrospectively define patient and injury characteristics, present our surgical methods and analyze our outcomes-namely infection, union and re-fracture rates...

Background: This survey aims to assess the satisfaction of patients who have had treatment using external fixation (EF). Materials and methods: An original questionnaire and a Short Form 36 (SF-36) were distributed to 121 patients who underwent treatment using EF for deformity correction and lengthening between 2006 and 2016. A multivariate analysis was performed on the factors associated with satisfaction. Results: Sixty patients returned a response...

PURPOSE: Comparison of two hexapod frame systems in paediatric tibial deformity correction; the Taylor Spatial Frame (TSF) and Orthex Hexapod System. METHODS: Paediatric patients with congenital and acquired tibial deformities treated with either TSF (between 2014 and 2016) or Orthex (between 2017 and 2019) frames were included in a retrospective comparative study. Outcome measures were healing index, pin infection rate, regenerate quality and density, software residual rate, deformity correction accuracy, strut exchanges and quality of life (QoL)...

Aim: We have encountered four cases with Taylor spatial frames (TSF) (Smith & Nephew, Memphis, TN, USA) with breakage at the half-ring junction of the distal ring. This study examines the strain produced on different locations of the distal ring during loading and the effects on the strain of altering the frame construct. Materials and methods: We mounted two ring TSF constructs on tibia saw bone models. The proximal ring was the same in all constructs and consisted of a 2/3 180 mm ring attached with three wires...

Deep learning techniques hold promise to develop dense topography reconstruction and pose estimation methods for endoscopic videos. However, currently available datasets do not support effective quantitative benchmarking. In this paper, we introduce a comprehensive endoscopic SLAM dataset consisting of 3D point cloud data for six porcine organs, capsule and standard endoscopy recordings, synthetically generated data as well as clinically in use conventional endoscope recording of the phantom colon with computed tomography(CT) scan ground truth...
