I'm afraid that I couldn't find the exact matching term but a close term would be αποφλοίωση (apofloíosi), which can be used to describe the removal of the outer layers in a surgical field, similar to how decortication is used.

See below some of the examples:
Surgical Techniques and Instruments: In orthopedic surgery, the procedure involving bone decortication might be discussed in surgical manuals or textbooks which explain the use of various burs and drills to modify bone structure.

Medical Research Papers: Studies involving surgical techniques like decortication for orthopedic surgeries might include detailed descriptions of the procedure, instruments used, and clinical outcomes.

Below are some of the references that discuss bone decortication and related procedures in medical contexts, which could help in understanding the application of such techniques:

The Role of Bone Decortication in Enhancing the Results of Guided Bone Regeneration:
This review article discusses the biological rationale and clinical application of bone decortication as part of guided bone regeneration procedures. It assesses various studies to determine the effectiveness of decortication in enhancing bone regeneration.

Clinical Results of Decortication with Bone Grafting Method versus Other Methods:
This study compares different surgical methods for treating non-union fractures, including those that use decortication with bone grafting. It provides clinical outcomes that highlight the efficacy of decortication in promoting bone healing.
