One constraint of preclinical research in the field of bone repair is the lack of experimental control over the local mechanical environment within a healing bone lesion. We report the design and use of an external fixator for bone repair with the ability to change fixator stiffness in vivo.

Segmentation of three-dimensional data from many imaging techniques is a major bottleneck in analysis of complex biological systems. Here, we describe the use of SuRVoS Workbench to semi-automatically segment volumetric data at various length-scales using example datasets from cryo-electron tomography, cryo soft X-ray tomography, and phase contrast X-ray tomography techniques.
FAQs
Preserving surrounding soft tissues and blood supply supports the repositioned bone segments while they heal. The technique therefore depends not only on making accurate bone cuts, but also on limiting disruption to structures that maintain segment vitality and stability. This principle is especially relevant when correction requires several mobile segments rather than one isolated adjustment.
A single cut may not provide enough control when a deformity involves several dimensions or requires changes in position, shape, and alignment at the same time. Segmental osteotomy allows individual portions to be repositioned in relation to one another, making it useful when a more localized or three-dimensional correction is needed.
Fixation devices hold the repositioned segments in their intended relationship while healing occurs. This stabilization helps maintain the correction achieved during surgery and supports structural continuity as the bone repairs. The final result therefore depends on both accurate segment placement and secure stabilization, rather than on the bone cuts alone.
The technique permits controlled adjustment of separate bone portions, allowing correction across more than one spatial aspect of a deformity. Surgeons can address differences in position, shape, and alignment together instead of treating the bone as a single rigid unit. This capability can improve structural relationships where a simpler cut would be insufficient.
The procedure includes creating controlled cuts, maintaining the surrounding soft tissues and blood supply, repositioning the resulting segments, and securing them with fixation devices. These stages connect surgical correction with healing: the cuts create mobility, repositioning establishes the desired alignment, and fixation preserves that arrangement until the bone stabilizes.
Segmental osteotomy is used in maxillofacial and orthopedic reconstruction to address skeletal deformities and restore functional alignment. In maxillofacial procedures, correction may support improved occlusion and symmetry; more broadly, repositioning can aid movement and structural function. Its value is greatest when reconstruction requires precise correction that a single bone cut cannot provide.
