“…Another possibility that may improve patient comfort or even make weight bearing possible for the patient is the application of a weight-bearing platform to the distal end of the frame in the case of a transfixed foot or soft tissue complications (Figure 1) [13,14]. Due to the modularity and variability of various frame mountings, which allow the orthopedic surgeon to adapt to any clinical situation, various frame configurations are in clinical use and exhibit good healing rates, but complications such as non- and mal-union continue to occur [15-18]. One cause of failure that may be detrimental to healing is the presence of excessive shear stresses produced by asymmetrical axial fracture site motion [19,20].…”

BackgroundA weight-bearing platform applied at the distal end of an Ilizarov external frame allows patients with hindfoot transfixations, foot deformities or plantar skin lesions to bear weight. This leads to an indirect loading of the fracture or osteotomy site. However, the effect on the fracture/osteotomy site's motion or compressive loads is unknown. The aim of this study was to analyze the mechanical effects of a weight-bearing platform on the traditional all-wire, four-ring frame in comparison to a two-ring frame consisting of half-pins.MethodsTwo frame configurations, with either anatomically positioned wires or half-pins, were analyzed with and without a weight-bearing platform applied underneath the distal ring. Composite tibiae with a mid-diaphyseal osteotomy of 3.5 mm were used in all the experiments. An axial load was applied with the use of a universal test machine (UTS®). Interfragmentary movements, the relative movements of bone fragments and movements between rings were recorded using displacement transducers. Compressive loads at the osteotomy site were recorded with loading cells.ResultsIndirect loading with a weight-bearing platform altered the force transmission through the osteotomy. Indirect loading of the tibiae decreased the extent of the axial micro-motion by 50% under the applied weight load when compared to direct weight loading (p < 0.05). The half pin frame was 25% stiffer than the wire frame under both direct and indirect loading of the tibiae (p < 0.05). Compressive loads under indirect loading were reduced by 67% in the wire frame and by 57% in the half-pin frames compared to direct loading of the bones (p < 0.05). While axial loading in the wire frames resulted in plain axial movements at the site of the osteotomy, it was coupled with translational movements and angular displacements in the half pin mountings. This effect was more apparent in the case of indirect loading.ConclusionsA weight-bearing platform has substantial influence on the biomechanical performance of an Ilizarov external fixator. Half-pins induce greater stiffness to the Ilizarov external fixator and allow the usage of only one ring per bone segment, but shear stresses at the osteotomy under axial loading should be considered. The results allow an estimation of the size and direction of interfragmentary movements based on the extent of weight bearing.

“… 18 – 21 However, frequent frame modifications and the need for sequential correction of deformities during bone transport are the main limitations of the Ilizarov device. 5 , 22 , 23 One of the problems is that deformity or translation may occur during transport, particularly in cases with large defects. In such cases, the conventional monolateral rail fixator or classic Ilizarov fixator requires additional procedures or components for correction, depending on the degree of deformity.…”

A bstract 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 mean age was 32.3 years; the femur was affected in one case and the lower leg in nine. Bone defects were due to infected non-unions in seven cases and bone tumours in three. The duration of external fixation, bone transport distance, distraction index (DI), alignment at the end of correction, leg length discrepancy, and complications were investigated. Results The average bone transport distance was 76.0 mm. The external fixation period averaged 367 days with the DI at 20.8 days/cm. Deformity at the docking site was assessed to have an average 2.6° deformity and 2.0 mm translation in the frontal view, as well as 3.3° deformity and 3.7 mm translation in the lateral view. The mean leg length discrepancy was 10.9 mm and the percentage of the mechanical axis (%MA) was 40.6%. Four patients underwent plate conversion after correction and two required additional surgery for non-union at the docking site. Bone union was achieved in all patients and there was no reaggravation of infection or tumour recurrence. Conclusion The TSF allowed for the correction of deformities and translations that occurred during bone transport giving excellent results. However, as with bone transport using this or other devices, additional procedures are often needed to obtain consolidation or docking site union.

“…Good results were seen in approximately 80%, fair results in 8-15% and poor results in 9-13% after a mean follow-up of four years. With the availability of various ring configurations, new struts and a new foot programme, indications for treatment with TSF could be extended to severe foot deformities [5,20]. Eidelman et al [5] reported on 13 patients with various foot deformities.…”

“…They concluded that treatment using TSF is a powerful and accurate surgical modality for both limb and foot deformities. Seybold et al [20] also used the TSF to correct post-traumatic limb and foot deformities, concluding that the application of the TSF is simple and patients need a shorter stationary period.…”

Abstract: The main advantage of the TSF compared with other external frames is the ability to perform simultaneous correction of angular, axial, translational, and rotatory deformities. This enables a reduced correction time and increased patient comfort.
