“…In these studies, in contrast to our method, no preoperative virtual 3D planning was used to keep the bone faces connected and to optimize for alignment. Instead, these procedures strongly rely on the surgeon’s skill in appreciating the deformity and restoring alignment 6 . In the technique that we propose, alignment planning is performed in six degrees of freedom, hereby minimizing angular and translational deformity in the coronal, sagittal and axial plane in one procedure, without additional bone loss due to wedge removal as in the case of a closed wedge osteotomy.…”

“…This axis is positioned in 3-D space such, that the transformation is achieved by rotating the object over an angle, β , about the helical axis and translating the object along the helical axis over a distance d . The rotational part of this method is used in an oblique single-cut rotation osteotomy (OSCRO) 4 – 6 , where the cutting plane is chosen perpendicular to the helical axis, and rotating the distal bone segment over the angle β yields rotational alignment. The parameter d is set to 0, which keeps the bone faces connected but introduces a translation error.…”

“…When rotational deformity (torsion) coexists with angular deformity, correction can be achieved using an oblique single -cut rotation osteotomy (OSCRO), in which the obliquity of the single cut is planned in a specific direction 4 – 6 . Subsequent rotation of the distal bone segment about the axis perpendicular to the oblique osteotomy plane yields rotational alignment in the sagittal, coronal and axial planes without bone loss, while maintaining bone contact 4 .…”

An oblique double-cut rotation osteotomy (ODCRO) enables correcting a complex bone deformation by aligning, in 3D, the distal, middle and proximal bone segments with a target bone, without intersegmental gaps. We propose virtual preoperative planning of an ODCRO. To minimize a residual translation error, we use an optimization algorithm and optimize towards bone length, alignment in the transverse direction, or a balanced reconstruction. We compare the residual alignment error with an oblique single-cut rotation osteotomy using 15 complex bone deformations. The single-cut approach was not feasible in 5 cases, whereas the ODCRO procedure was feasible in all cases. The residual alignment error was smaller for the ODCRO than for the single-cut approach except for one case. In a subset for length reconstruction, the length error of 7.3–21.3 mm was restored to 0.0 mm in 4 of 5 cases, although at the cost of an increased transverse translation. The proposed method renders planning an ODCRO feasible and helps restoring bone alignment and lengthening better than an oblique single-cut rotation osteotomy. Awareness of the challenges and possibilities in preoperative planning of an ODCRO will be of value for future alignment surgery and for patients.

“…We anticipate that the application of 3D imaging will revolutionize our understanding of Madelung deformity by providing a roadmap for the development of new morphological parameters for more objective diagnosis and classification. This new spatial assessment could also facilitate the use of innovative techniques such as 3D preoperative planning for osteotomies, 17 with the goal to more accurately restore normal anatomic and functional relationships.…”

Purpose 3D-printed patient-specific instruments (PSIs), such as surgical guides and implants, show great promise for accurate navigation in surgical correction of post-traumatic deformities of the distal radius. However, existing costs of computer-aided design and manufacturing process prevent everyday surgical use. In this paper, we propose an innovative semiautomatic methodology to streamline the PSIs design. Methods The new method was implemented as an extension of our existing 3D planning software. It facilitates the design of a regular and smooth implant and a companion guide starting from a user-selected surface on the affected bone. We evaluated the software by designing PSIs starting from preoperative virtual 3D plans of five patients previously treated at our institute for corrective osteotomy. We repeated the design for the same cases also with commercially available software, with and without dedicated customization. We measured design time and tracked user activity during the design process of implants, guides and subsequent modifications. Results All the designed shapes were considered valid. Median design times (t) were reduced for implants ((t I ) 2.2 min) and guides ((t G ) 1.0 min) compared to the standard ((t I ) 13 min and (t G ) 8 min) and the partially customized ((t I ) 6.5 min and (t G ) 6.0 min) commercially available alternatives. Mouse and keyboard activities were reduced (median count of strokes and clicks during implant design ((s I ) 53, and guide design ((s G ) 27) compared to using standard software ((s I ) 559 and (s G ) 380) and customized commercial software ((s I ) 217 and (s G ) 180). Conclusion Our software solution efficiently streamlines the design of PSIs for distal radius malunion. It represents a first step in making 3D-printed PSIs technology more accessible.
