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...

Range of motion assessment during total hip arthroplasty: Development and validation of a new instrument for range of motion measurement during total hip arthroplasty

Total Hip Arthroplasty (THA) is a procedure where a defective hip joint with pain symptoms or functional impairment is replaced by a hip prosthesis. During this procedure, the optimal hip prosthesis should be chosen and placed in the correct orientation to achieve a stable hip joint. Failure to do so can lead to dislocation, mechanical failure...
