(5) Some case reports have suggested an association between chronic bisphosphonate use and atypical insufficiency fractures
. These atypical femur fractures are characterized by their location (along the diaphysis in the region distal to the lesser trochanter), the patient's history (there may be minimal to no trauma), and the potential for "beaking" (localized periosteal or endosteal thickening of the lateral cortex).
Only two other reports of iliac wing insufficiency fractures
were found in the English literature.

In this time, we experienced the case of insufficiency fracture
in medial proximal tibia of the knee, which was caused by 2-year intravenous SFO administration induced hypophosphatemic osteomalacia.
DISCUSSION: Pelvic insufficiency fractures
one of the complications of radiation often presents with low back pain.
It includes hip osteoarthritis, trochanteric bursitis, iliopsoas bursitis, stenosis of the cervical spinal canal, pelvic or sacral insufficiency fracture
, muscle strain or tears, vascular claudication, myofascial referred pain, and facet arthropathy without stenosism, said Dr.
The differential diagnosis for LSS includes hip osteoarthritis, trochanteric bursitis, iliopsoas bursitis, stenosis of the cervical spinal canal, pelvic or sacral insufficiency fracture
, muscle strain or tears, vascular claudication, myofascial referred pain, and facet arthropathy without stenosis.
These investigators theorize that in elderly patients with osteoporotic bone, discontinuity of the medial meniscus results in loss of hoop stress distribution in the medial compartment thus increasing the load experienced in the femoral condyle and potentially predisposing patients to the development of subchondral insufficiency fracture
Subchondral insufficiency fracture
and total joint replacement were observed in 0.4% and 0.7% of tanezumab-treated patients, respectively, and were not observed in the other treatment groups.
