“…According to the literature, 43,65,66 the correction strategy, joint adjustment for equal bone distraction, is selected to linearly plan the position and orientation of the bone end to generate a smooth and uniformly spaced linear trajectory. According to the preset correction trajectory of the distal bone end, the motion simulation module is used to realize the overall alignment process of the bone end.…”

The Ortho‐SUV frame (OSF) is a hexapod external fixator widely applied in orthopedics deformity correction. The possibility of collision between OSF's struts and the soft tissue is an essential but overlooked issue. To avoid the issue, a novel collision detection algorithm is established based on a cone‐cylinder model of the tibial limb‐strut interaction for detecting the closeness of the tibial limb and external fixator. The algorithm is constructed using the vector analysis based on the model of the minimum distance between the truncated cone generatrix and the cylinder axis. The motion simulation is performed on the overall alignment through the Solidworks‐motion module to verify the feasibility of the algorithm. Subsequently, the installation parameter deviations of the bone‐fixator system are described to investigate the influence of orientation and position deviation on the closeness of the tibial limb and external fixator through the numerical method. The investigation results show that the orientation deviation γ (around the z‐axis), the position deviation τ1 and τ2 (along the x and y‐axes, respectively) have greater sensitivity to closeness and the influence of multiple deviations on the closeness has the property of superposition. The proposed algorithm can assist clinicians to strictly design and appraise frame configurations prior to their application to avoid the collision between the external fixator and the limbs during the correction. It has great application significance in the development of computer‐aided correction software.

BackgroundIn the field of orthopaedics, external fixators are commonly employed for treating extremity fractures and deformities. Computer‐assisted systems offer a promising and less error‐prone treatment alternative to manual fixation by utilising a software to plan treatments based on radiological and clinical data. Nevertheless, existing computer‐assisted systems have limitations and constraints.MethodsThis work represents the culmination of a project aimed at developing a new automatised fixation system and a corresponding software to minimise human intervention and associated errors, and the developed system incorporates enhanced functionalities and has fewer constraints compared to existing systems.ResultsThe automatised fixation system and its graphical user interface (GUI) demonstrate promising results in terms of accuracy, efficiency, and reliability.ConclusionThe developed fixation system and its accompanying GUI represent an improvement in computer‐assisted fixation systems. Future research may focus on further refining the system and conducting clinical trials.

“…9 When these parameters are changed, it becomes necessary to retrain the network, which will increase computational and time costs. Zhang et al 10 employed the genetic algorithm to plan the motion trajectory of TSF, aiming to reduce the pain caused by the orthopaedic process. Guo et al 11 introduced a method that combines the forward kinematics with multi-objective genetic algorithm.…”

AimTaylor 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.PurposeTo 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.MethodWe 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. We conduct simulation and physical experiment of orthodontic process respectively to prove the effectiveness of our method.ResultAfter optimization, the average offset during a single adjustment is less than 1 mm, and the offset during the whole orthopaedic process is reduced by about 38.8%.ConclusionIt demonstrates that our method can effectively reduce the offset of moving platform while ensuring orthopaedic accuracy.
