Clinical Trial Summary

The purpose of this study is to evaluate a new ceramic metal bone graft substitute for hemi craniectomies. The frequency of infections and rupture of skin will be studied, which is a reoccurring problem with currently used bone graft substitutes in this subject population. In addition, the quality of life before and after implantation will be evaluated as well as the bone regeneration around implant.

Accepts healthy volunteers No
Gender Both
Age group 18 Years and older
Eligibility Inclusion Criteria:

- Obtained informed consent.

- Males or females, =18 years of age

- Subject with cranial defect size > 25 cm2.

- History of previous cranial implant failure and where the latest cranial reconstruction failed within 12 months. (This means that the patient demonstrates a non-reconstructed cranial defect after removal of implant or exhibit an implant failure, e.g. local infection and/or protrusion through the skin.)

- Willing and able to comply with all study procedures and restrictions.

- The 5 subjects participating in bone regeneration analysis (PET/CT scans) has to be 50 years or older

Exclusion Criteria:

- Malignancy adjacent to the reconstruction area, including brain and calvaria, with on-going or planned surgical intervention.

- Pregnant or nursing women.

Exclusion criteria during surgery, if applicable:

Perioperative appearance of previously not identified tumor or infection in the reconstruction area.

Outcome

Type Measure Description Time frame Safety issue
Other Health economy variables Mean number of hospital days, hospital visits, mean time to adverse event and lost work days related to the study treatment will be counted. 3 months and 12 months post intervention compared to baseline visit: 3-0 weeks pre intervention
Primary Rate of adverse events The primary endpoint, rate of adverse events, will be measured by clinical evidence of infection and/or manifested rupture of skin around the implant, within 12 months, that necessitates explantation. From the date of intervention up to 12 months post intervention
Secondary Percentage subjects with an adverse event From the date of intervention up to 14 days, 3 months, 6 months follow-up
Secondary Quality of life scores SF-12 and EQ5D 3L will be used Assessed during the 3 month- and 12 month follow-up visit post intervention, compared to the screening visit: 3-0 weeks prior to intervention
Secondary PET/CT analysis with bone tracer, confirms bone regeneration activity within the reconstruction area The bone tracer (18 F fluoride) will be used to measure bone regeneration. The PET/CT scan will be taken at 12 months post intervention and it will be compared with 2 weeks post intervention
Secondary Subject mean MOCA Subject cognitive impairment is measured by Montreal Cognitive Assessment (MOCA) (the subject will be given a score after completing the assessment) 3 months and 12 months follow-up compared to baseline
