Objectives: To study the Efficacy of core decompression for treatment of canine femoral head osteonecrosis induced by arterial ischemia and venous congestion

Methods: 40 healthy mixed-breed dogs were randomly divided into two groups, arterial ischemia (AI) and venous congestion (VC), each containing 20 dogs. The dogs underwent a procedure where the deep femoral artery or deep femoral vein was ligated randomly on the left or right side to establish the femoral head osteonecrosis model. 13 dogs from each group, AI and VC, were randomly selected for subsequent study. Three dogs were randomly chosen from each group to receive core decompression (CD) every 2 weeks for a total of 4 sessions.

Results: The development of femoral head osteonecrosis was slightly slowed at each measurement time point after CD in the arterial ischemia (AI) group, but no restoration was observed. The venous congestion (VC) group showed a gradually reduced mixed signal after CD and exhibited a trend towards restoration. The various venous congestion (VC) subgroups had significantlyimproved symptoms than the arterial ischemia (AI) subgroups.

Conclusion: CD displayed greater treatment efficacy for femoral head osteonecrosis caused by venous congestion (VC), but poor efficacy for femoral head osteonecrosis caused by arterial ischemia (AI).
