Spring assisted cranioplasty: A patient specific computational model

Spring-assisted cranioplasty vs pi-plasty for sagittal synostosis--a long term follow-up study.

Spring-assisted cranioplasty (SAS) has been used for the treatment of selected cases of sagittal synostosis at our unit routinely since 1998. In order to assess the long-term outcomes of this procedure, we compared the clinical data and morbidity with the pi-plasty technique, our previous standard procedure for the treatment of such children. The first 20 consecutive patients who underwent SAS ...

Split-Rib Cranioplasty Using a Patient-Specific Three-Dimensional Printing Model

The reconstruction of cranial bone defects is necessary not just for the protection of the brain, but also for aesthetics. Cranial bone reconstruction may be conducted using autologous or synthetic bone tissue [1]. When synthetic bone is utilized, the reconstruction of large defects is possible, and problems with the donor area are eliminated. However, other possible problems include allergic r...

A Spring Assisted One Degree of Freedom Climbing Model

A dynamic model of running–the spring-loaded inverted pendulum (SLIP)–has proven effective in describing the force patterns found in a wide variety of animals and in designing and constructing a number of terrestrial running robots. Climbing or vertical locomotion has, on the other hand, lacked such a simple and powerful model. Climbing robots to date have all been quasi-static in their operati...

Symptomatic tension pneumocephalus following Palacos® cranioplasty in a shunted patient.

Tension pneumocephalus is an exceedingly rare complication of cerebrospinal fluid diversion occurring after surgery, trauma or spontaneous fistula formation. We report a case in a patient with a ventriculoperitoneal shunt who developed symptomatic tension pneumocephalus via a skin defect within 24 hours of undergoing bone cement cranioplasty.
