[Corion Interposition Arthroplasty after Post-Traumatic Metacarpophalangeal Cartilage Defects - Two Case Reports]

We report on the long-term results of 2 patients after saw injury by restoration of metacarpophalangeal joint II with bone graft from the iliac crest and interposition arthroplasty of the corion. Clinical and radiological controls were performed in the 6(th) and 8(th) post-operative years, respectively. The DASH scores (11.6 and 18.3, respectively) and range of motion (60 and 70° respectively) were associated with no pain and satisfaction with the results of the operation for both patients. In summary, the reconstruction of selected cases of metacarpophalangeal joint defects with iliac crest and corium interposition arthroplasty is a good treatment option.
