A process on the proximal end of the femur in many vertebrates, which serves for muscle attachment and, in birds, for articulation with the ilium.
(invertebrate zoology)

Overall several different classification systems have been developed including the Russell-Taylor classification which is based on the presence of lesser trochanter comminution and fracture extension into the piriformis fossa which helped to guide treatment prior to the development of trochanteric start point intramedullary nails.
Presenting symptoms of lesser trochanter avulsion fractures can be vague, but are usually localized to the groin and medial hip region.
A long-stem prosthesis allows the distal medullary cavity to bear weight, and bridges the holes for internal fixation.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 metaphysial canal flare indices were the ratio of intracortical widths at the proximal extremity to at the distal extremity of lesser trochanter. 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., 2006-2008).
Nash and Harris reported clinically significant differences in cortical thickness at 10 cm below the lesser trochanter, among Dorr proximal femur morphology [41].
Ischiofemoral impingement (IFI) is characterized by a narrowed space between the ischial tuberosity and the lesser trochanter resulting in repetitive impingement of the quadratus femoris muscle (Figure 4).

The top of the femur shaft has two eminences (bumps): the great and lesser trochanters, where many muscle tendons attach.
(4,15) Loss of flexion strength has been described immediately postoperatively, but full return to play is expected after psoas tendon release, both at the capsular level and at the lesser trochanter. (18-20) Releasing the tendon at the joint level only affects about half of the psoas muscle and none of the iliacus muscle, while releasing the psoas tendon at the level of the trochanter leaves the iliacus insertion on the proximal femur intact.
Patients with fracture of femur between inferior margin of lesser trochanter and upper border of a square containing the distal end of the femur, closed and grade I open fracture were included.
As it is shown in figure, femoral bone is composed of head, neck, greater and lesser trochanter, body, medial and lateral condyles.
"First, there were a lot of reports in Singapore of unusual hip fractures before the lesser trochanter, [with] unusual x-ray changes," Dr.
