Development and validation of a bone quality measurement method integrated into the freehand drilling process

<b>Background:</b> Low bone quality associated with osteoporosis is an increasing health issue. The reduction in bone quality increases the risk of bone fractures and implant failure in osteosynthesis. Implant failure can be avoided by adapting the surgical procedure and postoperative care to the bone quality. This requires knowledge of the...

Implementations of a Compact Drilling System (CDS) for bone

Bone drilling is a surgical action required for bone fixation using plates. The holes are currently drilled using a large, conventional drill. This causes problems when limited space is available, de to the size of the drill. For that reason a new, small Compact Drilling System is proposed. In earlier research a compact self-feeding mechanism...

Design of a combined optical and structural bone phantom: Concept validation and design tool

Introduction: Although being the most advanced spinal stabilization method, pedicle screw fixation has an increased number of complications compared to other surgical procedures, due to the complex spinal anatomy, large inter-patient anatomical variability, and the highly vulnerable surrounding tissue of the spine. Screw fixation strength can be...

The Design of a Compact Angular Drilling Device for Medical Application

The technology used in health care is one of the fastest developing fields in Precision Engineering. The main focus in this field is on the development of steerable, small dimensioned instruments. Using these, surgeries can be done with minimal damage to the patient, shorter hospital stay and more aesthetical healing.<br/>From the medical field...
