Subchondral fracture Femoral head Collapse

Subchondral stress fracture of the femoral head
(SSFFH) is a rarely encountered condition. It occurs
not only as an insufficiency-type stress fracture
in elderly people or in renal transplant
recipients,1–10 but also as a fatigue-type stress
fracture in healthy adults.11,12 As in osteonecrosis
of the femoral head, which has very similar clinical
features and imaging findings,1–6,13–15 collapse of
the femoral head can occur in fatigue-type
SSFFH.11,12,16 It is well known that once collapse
of the femoral head takes place in osteonecrosis
of the femoral head, the hip joint deteriorates rapidly
and an arthroplasty is eventually necessary in
most cases.17,18 However, little is known about the
fate of collapsed fatigue-type SSFFH.
The authors hypothesized that the fate of collapsed
fatigue-type SSFFH probably differ from
that of collapsed osteonecrosis of the femoral
head because they are similar but quite separate
disease conditions. The authors expected
a much better prognosis in collapsed subchondral
stress fractures because they have an intact blood
supply and healing potential. In this study, the authors
retrospectively evaluated the clinical course
of collapsed fatigue-type SSFFH in nine patients.
