Presenting symptoms of lesser trochanter
avulsion fractures can be vague, but are usually localized to the groin and medial hip region.
8 Dislocation of greater and lesser trochanter
due to fracture is reduced and fixed with steel wire or cable to restore the muscle attachments.
The canal flare index (CFI) was the ratio of the intracortical width at the proximal level of lesser trochanter
point and at the isthmus (Palierne et al.
8) On MRI, decreased space between the ischium and lesser trochanter
is often identified as a risk for IFI.
Impingement of lesser trochanter
on ischium as a potential cause for hip pain.
Also, the femoral head, the ischiadic tuberosities (the lowest parts of the pelvis), the greater and the lesser trochanter
can be approximated by parts of circles.
Furthermore, prosthetic replacement is associated with problems in such a fracture as it extends beyond the lesser trochanter
involving the calcar and will leave a gap on the medial aspect, after a routine neck cut is made.
One of the most frequently affected muscles is the iliopsoas, the main flexor of the thigh, which originates in the retroperitoneum in the bodies of the lumbar vertebrae and crosses the pelvis before its insertion in the lesser trochanter
of the femur.
Psoas major and minor both insert on the lesser trochanter
of the femur (4).
On hip scans, be sure the hip was imaged in the correct position, with the femoral shaft straight up and down and with sufficient internal rotation on the leg so that little or none of the lesser trochanter
The iliopsoas runs in your abdomen behind the organs, along the front of the spine, and ends at a point in the inner leg called the lesser trochanter
S -- Shenton's line (or Shenton's curve): Runs from the top of the obturator foremen and the medial cortex of the femoral neck to the lesser trochanter
