Computational Spine Biomechanics

The focus of the pediatric orthopedic research groups is the assessment and modeling of spinal and pelvic biomechanics and their implementation in new surgical strategies for the treatment of spinal deformities and pelvic tumors tailored to the individual patient’s anatomy and biomechanics.  

In translational spine reasearch (Prof. Carol-C.Hasler), retrievement of in-vivo data on the stiffness of spinal segments and the creation of a patient-based finite element model of the deformed spine are the core activities. Thereby, the current surgical gold standard of multisegmental spinal fusion for scoliosis around puberty or growth promoting strategies based on incremental, half-yearly lengthening of implants (growing rods, VEPTR) shall be replaced by motion-preserving strategies. A cluster of subprojects aims at filling the existing lack of knowledge about the biomechanics of the growing, deformed spine and at providing new, motor-driven expandable implants and more functional spinal anchors in collaboration with a strong medtech industry partner.  

The limp-preserving reconstruction of large pelvic defects after tumor resection, particularly around the hip joint, is a big surgical challenge. Although it is a viable alternative to high amputation or arthrodesis, it is prone to complications (infection, loosening) and loss of function. One of the main reasons is the application of inappropriate "off-the-shelf" implants which do not reflect the patient’s individual 3D pelvic anatomy and biomechanics.

The orthopedic tumor group (PD Dr. Krieg) matches the patient’s anatomy to statistical pelvic shapes and a pelvic finite element model based upon multiple measurements of CT scans and biomechanical testing  of cadaver pelvis. Moreover, these data enable an innovative industrial partner to create an individualized pelvic implant. Initial clinical applications of such titanium mesh grafts are promising in terms of anatomic fit, anchorage, biologic integration and patient rehabilitation.

List of main projects

  • In-vivo pre- and intraoperative assessment of segmental spinal sitffness by traction in combination with 3D radiographs and by a motorized, hexapod-based device combined with spinal navigation, respectively
  • Ex-vivo assessment of pelvic biomechanic properties and creation of a pelvic statistical shape model
  • Finite element models of the growing scoliotic spine and the pelvis
  • New non-fusion strategies, motor-driven implants and spinal anchorage for deformities of the growing spine
  • Modeling, fabrication and implantation of individualized implants for reconstruction of pelvic defects after tumor reconstruction
