The TAYLOR SPATIAL FRAME™ for External Fixation: A Systematic Literature Review Following 20 years of Clinical Outcomes Study characteristics  This systematic review was performed to evaluate and summarize the current evidence of the clinical performance of the TAYLOR SPATIAL FRAME (Smith & Nephew, Memphis, TN, USA). Background  Since its introduction in 1996, several studies have reported positive clinical results with the TAYLOR SPATIAL FRAME external fixator. In order to obtain a more thorough understanding of this device’s performance, we conducted a systematic review of the literature...

External fixation plays a growing role in the primary treatment of unstable and high risk fractures, non- and malunions, as well as in the reconstruction of congenital and acquired physical deformities. TAYLOR SPATIAL FRAME (Smith & Nephew, Memphis, TN, USA; Figure 1) is an external fixator that uses computer software to simultaneously correct for leg length discrepancy and various aspects of deformity including angulation, translation, and rotation. TAYLOR SPATIAL FRAME consists of two rings or partial rings connected by six telescopic struts at special universal joints to create a hexapod...

Although some of the 44 studies were of greater than Level IV evidence, for our purposes they are all considered Level IV case series. This is because only one study arm was included or the study arms were considered independently of one another. Please refer to Appendix 1: Methods for further detail on the eligibility criteria and literature search. This review pools data from clinical studies reporting consolidation rates, time to consolidation, rate of correction goals achieved (specific to deformities), and complications following treatment with TAYLOR SPATIAL FRAME™ in adults and...

Results Cont. Correction Goals Achieved—Adults and Children The total number of correction goals achieved, a commonly reported outcome in the indication of deformities, was 98.1% for adults (7 studies2,8,15,20,26,34,43) and 94.3% in children (14 studies6,8-14,16,17,19,20,22,35).

Results Cont. Complication Rates Total number of complications were pooled from the included articles that investigated TAYLOR SPATIAL FRAME™. For all three indications combined, the overall rate of complications per fracture or deformity was 43.0% and 54.2% in adults and children, respectively. These complications were classified according to severity using a modified grading system by Donnan et al45 (see Appendix). Grade I complications do not require operative interventions, whereas Grades II–IV do. Incidence rates were developed for the following categories: no complications,...
