Inclusion criteria
Inclusion criteria: 1.Patient must be at least 18 years of age (or older if required by local regulations) 2.Patient scheduled for an orthopaedic surgical procedure provided that the required amount of trans-operatory collection of bone and skin as defined per-protocol in section 5.1.3 is feasible and all inclusion and no exclusion criteria are met. 3.Patient is scheduled to have sufficient bone removed during the orthopaedic surgical procedure and sufficient non-scarred skin tissue from the edge of the surgical incision or amputated part to permit sample collection, in the investigatorâ??s medical opinion 4.Patient agreed to have bone and skin samples collected at the time of the surgical procedure(s) 5.Patientâ??s surgical procedure and subsequent remission will not be altered by study specific skin biopsies, in the investigatorâ??s medical opinion 6.Patient is fully informed about the study and has signed the informed consent form
Exclusion criteria
