Assessment of the distribution of load on the lower limbs and balance before and after ankle arthrodesis with the Ilizarov method. An additional advantage of Auto Strut utilization is the elimination of the burden associated with the manual adjustments. A treatment plan for the strut adjustment was generated based on the characteristics of the limb deformity and hexapod external fixator mounting and then downloaded into the Auto Strut central control box. Both during grasping and fixation tasks, the image processing algorithm estimates the relative roto-translation (6 degrees of freedom pose parameters) from the camera to the target.

The main processing flow starts with a predicted pose that must be initially provided by means of robot kinematics and trajectory planning. The treatment duration, correction success and adverse events observed in our study indicate that utilizing the Auto Strut device with the hexapod external fixator for automatic gradual deformity correction is safe and as accurate as manually adjusted struts.6,11,14,20 Manual strut adjustment is dependent on patient/patient family collaboration and is prone to errors. The system can be adjusted to perform a continuous distraction compression schedule, the ‘accordion’ motion (an accepted technique to speed bone healing in cases delayed or nonunion), as well as any other appropriate schedules. 60 days of distraction for bilateral tibial genuvarum correction and lengthening, using Auto Struts over an circular cexapod external fixator system.

Limb lengthening and deformity correction of congenital and acquired deformities in children using the Taylor Spatial Frame. We believe that Auto Strut can successfully replace the manual strut adjustment method and provide several important advantages that benefit the patient, the caregiver, the surgeon and may have important future research implications. We have presented the successful utilization of an automated hexapod external fixator in the treatment of bone deformities. A treatment with a hexapod external fixator, in which the manual struts were substituted with the Auto Strut automatic device, has been initiated in ten 12- to 20-year-old patients (five girls).

As a programmable multi-purpose device, it allows the implementation of diverse treatment schedules and, therefore, is applicable to the treatment of diverse bone impairments, including, nonunion, correction of bone deformities and segmental defects. Combining existing dual quaternion-based pose-tracking controllers with the proposed dual quaternion framework for the modeling of the multibody robotic servicer allows for the use of a unified algebra to model the different phases, ranging from navigation, to grappling and servicing. Although the malfunction was solved, the Auto Strut device was replaced with manual struts as the patient preferred not to go back to the Auto Strut. The alarm system was activated twice in one patient (patient 02), indicating a device malfunction (connector assembly problem). Details on the planned corrections, distraction and consolidation parameters and treatment duration are presented in Table 2. Nine patients received unilateral treatment (seven left limbs and two right limbs) and patient 09 was treated bilaterally.

The proposed guidance algorithm is a variation from a guidance approach suitable for onboard implementation and real-time use previously developed for capture-only maneuvers (Virgili-Llop et al., 2017b,c, 2019). Here, the detumbling of the RSO is added as additional terminal conditions to this previously developed guidance approach. Although these aerodynamic perturbations are usually perceived as drawbacks, they can also be seen as an advantage (Virgili-Llop, 2014; Virgili-Llop et al., 2014a). As the orbital lifetime is reduced, there is no need to de-orbit spacecraft at the end of their operational life. Uploading the treatment plan to the device can be easily done, using a computer with a USB-cable-mediated connection to the central control box. Future developments will increase its modularity, allow the collection of information associated with bone healing, such as the parameters of bone resistance during various treatment stages, which may be indicative of the maturity/strength of the newly formed bone.
