BackgroundThe outcome of total wrist prostheses is disappointing due to complications, mainly loosening or absence of osseointegration. The main reason is poor placement. The aim of this study was to examine whether computer‐assisted surgery (CAS) was advantageous in wrist prosthesis implantation.
MethodsOur study group comprised eight patients. Group I was operated on with CAS and Group II without...
BackgroundNowadays, there is a trend towards computer‐aided oral and maxillofacial surgery. However, due to complicated preoperative planning, traditional neurosurgery‐orientated navigation systems are not suitable and have to be adapted.
MethodsA surgical navigation system is presented for oral and maxillofacial surgery, named AccuNavi, which integrates 3D medical modelling, preoperative surgical...
Background
In orthopaedic trauma surgery, image‐guided procedures are mostly based on fluoroscopy. The reduction of radiation exposure is an important goal. The purpose of this work was to investigate the impact of a camera‐augmented mobile C‐arm (CamC) on radiation exposure and the surgical workflow during a first clinical trial.
Methods
Applying a workflow‐oriented approach, 10 general workflow...
The porous structure of the implant contributes significantly to prosthetic osseointegration in cranio‐maxillofacial defect repair surgeries. This study establishes a system called EasyImplant that can easily and efficiently design customized cranio‐maxillofacial implant with porous structure. Healthy side of the skull model is used to obtain the initial implant model on defective side by mirroring...
Background
With unilateral pelvic fractures, the contralateral hemipelvis can be used as a template in virtual reconstruction; however, this cannot be applied for bilateral fractures. Therefore, statistical shape modelling was used to build average pelvic shapes that can serve as templates when reconstructing bilaterally fractured pelvises.
Methods
Four average shape models were created for male...
Background
The patient‐specific templates for osteotomy often have complex surface features. Using current commercial software to design such templates is quite complicated, tedious and unrepeatable.
Aims
In this study, a novel surgical planning system for oral and maxillofacial surgery named EasyTemplate is developed, aiming to help doctors shorten the modelling time and assure the reliability...
