This study aims to evaluate the clinical efficacy of core decompression with bone grafting combined with perifemoral arterial infusion (CDBG-AI) in treating stage I-II osteonecrosis of the femoral head (ONFH). A total of 40 patients (40-70 years old) with stage I-II ONFH were enrolled. Initially, these patients underwent core decompression plus implantation of allogeneic bone and CaSO4 particle...

PURPOSE OF THE STUDY Osteonecrosis of the hip mostly affects young individuals and often progresses to a debilitating disease. Several treatment modalities exist, but none are completely satisfactory. This study evaluates the clinical outcome of patients treated with core decompression and insertion of a porous tantalum implant in the femoral head. This procedure is similar to commonly performe...

This paper discusses an integrated solution for reducing the volume of test data for deterministic system-on-achip testing. The proposed solution is based on a new test data decompression architecture which exploits the features of a core wrapper design algorithm targeting the elimination of useless test data. The compressed test data can be transferred from the automatic test equipment to the ...

Objectives: Avascular necrosis (AVN) of the hip is caused by interruption blood flow to femoral head, resulting in pain, loss joint function, and eventual arthritis. Core decompression may be performed for early AVN with a goal improving symptoms potentially delaying need THA. The effectiveness this procedure generally not well understood given relatively rare nature AVN. predictors conversion ...
