Taylor spatial frame

OBJECTIVES: Multi-planar external fixation has been used for the management of segmental tibial fractures with severe soft tissue injuries. However, fewer specialized studies have been reported. The primary aim of this study was to describe our experience of treating fractures of this type using the Taylor Spatial Frame and Ilizarov external fixation methods. METHODS: We retrospectively analyzed 33 patients with segmental tibial fracture treated at our institution between January 2016 and December 2020...

BACKGROUND: Grade III open tibial diaphyseal fractures are challenging to treat and controversy exists on whether to treat them with an intramedullary nail (IMN) or a circular frame (CF). This study aims to compare outcomes for intramedullary nail and circular frame in the treatment of open tibial diaphyseal fractures. METHODOLOGY: Retrospective study at a major trauma center of all patients admitted with a grade III open tibial diaphyseal fracture between January 2016 and January 2022...

The incidence of deep surgical site infections following high tibial osteotomy (HTO) ranges between 0.4 to 4.7%. It is a severe complication with a high risk for poor clinical outcome. The aim of this study was to proof that a salvage algorithm for infected HTO with unstable bone situation leads to an infection-free status and bone union of the osteotomy and that correct limb alignment can be restored with good knee function.The study included seven patients with peri-implant infections following HTO. Infections occurred 83 ± 58...

AIM: Taylor spatial frame (TSF) is a kind of six-axis external fixator based on Stewart platform, which is widely used in the fields of trauma orthopaedics and orthopaedic reconstruction. PURPOSE: To reduce the irregular movement of TSF's moving platform during orthopaedic process and decrease the risk of complications caused by collision between bone and surrounding tissue. METHOD: We combine the kinematics solutions with the multi-objective genetic algorithm and ant colony optimization to get the optimal solution for adjustment of strut length and order...

Circular external fixators (CEFs) are successfully used in orthopedics owing to their highly favorable stiffness characteristics which promote distraction osteogenesis. Although there are different designs of external fixators, how these features produce optimal biomechanics through structural and component designs is not well known. Therefore, the aim of this study was to conduct a review on CEFs following the PRISMA statement. A search for relevant research articles was performed on Scopus and PubMed databases providing the related keywords...

OBJECTIVE: Correction of deformities around the knee joint in the frontal and sagittal axis, torsion, length and translation. INDICATIONS: Complex deformities of the proximal tibia, and to a lesser extent of the distal femur, which cannot be treated with acute correction using plate or nail osteosynthesis. CONTRAINDICATIONS: Nicotine abuse, soft tissue problems, lack of patient compliance. SURGICAL TECHNIQUE: First, mounting of the proximal ring of the ring fixator strictly parallel to the joint line in 2 planes, fixation with 3 or 4 pins or wires...

AIM: Bone transport is a beneficial reconstructive method for bone defects caused by infected non-unions or bone tumours. The Taylor Spatial Frame (TSF) is a three-dimensional corrective external fixator that can be used to achieve bone transport and correct any residual deformities easily at any time. This study reports the results of bone transport using TSF. MATERIALS AND METHODS: This is a retrospective study of ten patients who underwent bone transport using the TSF...

The history and development of circular fixation is closely aligned with the history of limb lengthening. Gavriil A. Ilizarov not only developed his circular fixator, but he also was the first to research and publish on distraction osteogenesis. Progress and dissemination of the method was initially based on individual pioneers; a standardized nomenclature and annual courses led to a wider dissemination. The introduction of the Taylor spatial frame in 1997 was a game changer. Although various groups had already developed Hexapod-fixators, it was the TSF that hit the market and achieved market presence...

A line illumination Raman microscope extracts the underlying spatial and spectral information of a sample, typically a few hundred times faster than raster scanning. This makes it possible to measure a wide range of biological samples such as cells and tissues - that only allow modest intensity illumination to prevent potential damage - within feasible time frame. However, a non-uniform intensity distribution of laser line illumination may induce some artifacts in the data and lower the accuracy of machine learning models trained to predict sample class membership...

BACKGROUND: Pediatric patients with leg length discrepancies and complex deformities may require multiplanar external fixators for correction. We have encountered 4 cases of half-pin breakage with the Orthex hexapod frame. The purpose of this study is to report factors associated with half-pin breakage and compare various deformity correction characteristics between 2 hexapod frames - Taylor Spatial Frame (TSF) and Orthex. METHODS: Pediatric patients with lower extremity deformities treated with an Orthex or TSF at a single tertiary children's hospital between 2012 and 2022 were included for retrospective review...

BACKGROUND: Several studies demonstrated a considerable complication rate for open ankle or TTC arthrodesis in patients with diabetes, revision surgery and ulceration. Extensive approaches in combination with multimorbide patients have been suggested as the rationale behind the increased complication rate. METHODS: Single-centre, prospective case-control study compared arthroscopic vs. open ankle arthrodesis in patients with Charcot Neuro-Arthropathy of the foot...

The large-scale laminar/turbulent spiral patterns that appear in the linearly unstable regime of counter-rotating Taylor-Couette flow are investigated from a statistical perspective by means of direct numerical simulation. Unlike the vast majority of previous numerical studies, we analyse the flow in periodic parallelogram-annular domains, following a coordinate change that aligns one of the parallelogram sides with the spiral pattern. The domain size, shape and spatial resolution have been varied and the results compared with those in a sufficiently large computational orthogonal domain with natural axial and azimuthal periodicity...

INTRODUCTION: Traditional Ilizarov and hexapod frames have different biomechanical properties and there is limited literature regarding their effect on time to fracture union or time to frame removal. METHODS: Tibial fractures managed with a circular frame at a tertiary limb reconstruction referral centre between 2011 and 2018 were retrospectively identified from a prospectively maintained database. They were classified into three treatment groups; Ilizarov style, Taylor Spatial Frame (TSF) and TrueLok Hex (TL-Hex)...

BACKGROUND: U-osteotomy with Taylor Spatial Frame correction is a rarely reported treatment method particularly well-suited for severe rigid equinus deformity in adults. The purpose of this study was to evaluate the effectiveness and efficacy of deformity correction and clinical outcome using this technique. METHODS: We present a retrospective review of 30 feet in 26 patients who received U-osteotomy with Taylor Spatial Frame. Radiologic outcomes were measured using the anterior tibiotalar angle (TTA) with conventional weightbearing radiographs...

BACKGROUND: High energy open tibial fractures are complex injuries with no consensus on the optimal method of fixation. Treatment outcomes are often reported with union and re-operation rates, often without specific definitions being provided.  We sought to describe union, reoperation rates, and patient reported outcomes, using the validated EQ-VAS and Disability Rating Index (DRI) scores, following stabilisation with a Taylor Spatial Frame (TSF) and a combined orthoplastic approach for the management of soft tissues...

BACKGROUND: Hemophilic arthropathy is a cause of severe knee deformity, because chronic synovitis due to repeated hemarthrosis affects the area of the epiphyseal plates in juvenile cases. Total knee arthroplasty (TKA) is the standard treatment for end-stage knee arthropathy. However, it is difficult to perform one-stage TKA in patients with severe intra- and extra-articular deformities. CASE PRESENTATION: We reported a case of hemophilic arthropathy in a 55-year-old male with leg length discrepancy of 4 cm, limited range of knee motion (-40° extension and 85° flexion), intra-articular deformity (medial proximal tibial angle: 69°; mechanical lateral distal femoral angle: 79°), extra-articular deformity at the distal femoral metaphyseal (30° valgus and 45° flexion deformity), and varus malalignment (% mechanical axis: 33%)...

BACKGROUND: Surgical management of Torsional Malalignment Syndrome (TMS) traditionally consists of simultaneous correction of both femoral anteversion and external tibial torsion. We hypothesise that a single supra tubercular osteotomy followed by tibial derotation with Taylor Spatial Frame (TSF) is sufficient to provide significant improvement in both appearance and function. METHOD: This is a retrospective single surgeon case series performed at a tertiary referral centre in the UK...

BACKGROUND: In clinical practice, even when the fixator is locked, a noticeable laxity of the construct can be observed. This study was designed to measure the stiffness of the fixator and to analyze the movements of the osteotomy site. Furthermore, the effect of three additional longitudinal rods on the locking of the construct was analyzed. METHODS: Five synthetic tibia/fixator models (Model A) were tested under rotational torque (40 Nm) and axial compression (700 N)...

AIMS: The aim of this retrospective cohort study was to assess and investigate the safety and efficacy of using a distal tibial osteotomy compared to proximal osteotomy for limb lengthening in children. METHODS: In this study, there were 59 consecutive tibial lengthening and deformity corrections in 57 children using a circular frame. All were performed or supervised by the senior author between January 2013 and June 2019. A total of 25 who underwent a distal tibial osteotomy were analyzed and compared to a group of 34 who had a standard proximal tibial osteotomy...

Competitive indoor climbing has increased in popularity at the youth, collegiate, and Olympic levels. A critical aspect for improving performance is characterizing the physiologic response to different climbing strategies (e.g., work/rest patterns, pacing) and techniques (e.g., body position and movement) relative to location on climbing wall with spatially varying characteristics (e.g., wall inclinations, position of foot/hand holds). However, this response is not well understood due to the limited capabilities of climbing-specific measurement and assessment tools...
