Evaluation of Patients' Posture and Gait Profile After Lumbar Fusion Surgery by Video Rasterstereography and Treadmill Gait Analysis

Sebastian Scheidt^1,2, Ulf Krister Hofmann², Falk Mittag²

¹Department of Orthopedics and Trauma Surgery, University Hospital Bonn, ²Department of Orthopedic Surgery, University Hospital Tuebingen

Here, we present a protocol to analyze the posture and the gait of patients after lumbar fusion surgery by means of high-resolution video rasterstereography and a treadmill equipped with an integrated sensor mat. Allowing critical functional postoperative evaluation on a less subjective level may enhance accuracy and reliability of indication for surgery.

¹Laboratory of Cell Biology, Department of Orthopaedic Surgery, University Hospital of Tübingen, ²Medical faculty of the University of Tübingen, ³Department of Orthopaedic Surgery, University Hospital of Tübingen

We present a method to investigate early osteoarthritic changes at the cellular level in articular cartilage by using atomic force microscopy (AFM).

Injection of Porcine Adipose Tissue-Derived Stroma Cells via Waterjet Technology

Jasmin Knoll^*1, Marina Danalache^*2, Walter Linzenbold³, Markus Enderle³, Tanja Abruzzese¹, Arnulf Stenzl¹, Wilhelm K. Aicher¹

¹Department of Urology, University Hospital Tübingen, ²Department of Orthopaedic Surgery, University Hospital Tübingen, ³ERBE Elektromedizin GmbH Tübingen

We present a method of cell injection via needle free waterjet technology coupled with a sequela of post-delivery investigations in terms of cellular viability, proliferation, and elasticity measurements.

5-Aminolevulinic Acid-mediated Photodynamic Therapy on Primary Bone Tumor and Bone Metastases Cell Lines

Saskia Magdalen Sachsenmaier^*1,2, Christian Walter^*2, Chen Liang^1,2, Rosa Riester¹, Nikolaus Wülker^1,2, Marina Danalache¹

¹Laboratory of Cell Biology, Department of Orthopaedic Surgery, University Hospital of Tübingen, ²Department of Orthopaedic Surgery, University Hospital of Tübingen

This protocol presents a step-by-step methodological approach of exposing bone metastatic cells lines and primary bone tumors to 5-aminolevulinic acid-mediated photodynamic therapy (PDT). The effects on cell migration potential/invasiveness, viability, apoptosis, and senescence potential are also analyzed following PDT exposure.
