Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the initial stage of the reconstructive surgery, the orthopedic surgeon, using a crown drill and a guide with an olive, takes cylindrical fragments of the spongy bone from the side of the proximal part. The collection of the graft takes about 5 minutes and is made of a skin cut with a length of 15 millimeters. During follow-up visits (2 weeks, 6 weeks, 12 weeks and a year and 2 years after the surgery) at the orthopedic clinic, the aesthetics of the scar and symptoms from the graft collection site will be assessed. As the control group will have their transplants collected from another place, the study cannot be randomized.

Comparator / control treatment
In the initial stage of the reconstructive surgery, the orthopedic surgeon, using a crown drill and a guide with an olive, takes cylindrical fragments of the spongy bone from the side of the iliac region. The collection of the graft takes about 5 minutes and is made of a skin cut with a length of 50 millimeters. During follow-up visits (2 weeks, 6 weeks, 12 weeks and a year and 2 years after the surgery) at the orthopedic clinic, the aesthetics of the scar and symptoms from the graft collection site will be assessed.

Outcomes
Primary outcome [1] 327014 0
Assessment of the volume of the harvested graft. It will be made by using a milliliter-graduated vessel into which 10 ml of saline will be poured, and then bone material will be placed and the level of liquid in the vessel will be re-evaluated.
