The primary safety endpoint evaluated a composite measure of adjudicated outcomes of RPOA type 1 or type 2, subchondral insufficiency fracture, primary osteonecrosis or pathological fracture through 80 weeks (56 weeks of treatment plus a 24-week safety follow-up period).
Although the absence of atypical femoral fractures or cases of osteonecrosis of the jaw is reassuring, the authors note that their trial was underpowered to assess these uncommon events.
Spontaneous osteonecrosis of the knee (SONK) was first reported in 1968 by Ahlback.[1] It was defined as a distinct clinical entity with characteristic findings including a subchondral lesion in the weight-bearing region of a single condyle.
Patients and Methods: All cementless total hip arthroplasty (THA) patients operated for Osteonecrosis of femoral head (ONFH) in UNIT 3 were included.
Findings conducted from this study were positive and significant, as this is the first study to investigate the effects of anti-IL-6 therapy on femoral head osteonecrosis. The results indicated both a decrease in hip synovitis score and significant increase in bone rebuilding.

Magnetic resonance imaging (MRI) of the left ankle revealed a vertical crack in the talar body extending from the center of the talar dome to the subtalar joint and a lateral talar body fragment with low signal intensity on both T1-weighted and short T1 inversion recovery images suggestive of osteonecrosis (Figures 2(a) and 2(b)).
