Key result
Resection of the lesser trochanter increased hip range of motion and decreased femoral head translation by eliminating contact between the femur and pelvis in a cadaveric model.
Why the study?
Does lesser trochanteric resection improve hip range of motion and decrease femoral head translation in a cadaver model of ischiofemoral impingement?
Does lesser trochanteric resection improve hip range of motion and decrease femoral head translation in a cadaver model of ischiofemoral impingement?
Lesser trochanteric resection may provide physical benefit for patients with ischiofemoral impingement by increasing range of motion and decreasing femoral head translation.
Cadaveric benefits of lesser trochanter resection do not yet justify clinical use; leaves open efficacy in ischiofemoral impingement patients.
Ischiofemoral impingement (IFI) occurs due to the diminishing of space between the ischium and lesser trochanter. During a robotic hip study, one hip presented with indications of IFI, an opportunity to explore the pathophysiology and treatment strategies for this unusual condition. This specimen underwent kinematic tests in two states: (i) native lesser trochanter and (ii) resected lesser trochanter. The 'Resected lesser trochanter' state was found to increase the hip range of motion and decrease femoral head translation by eliminating contact between the femur and pelvis. These results suggest that lesser trochanteric resection would provide physical benefit for IFI patients.

Murata et al. (2020) studied Ischiofemoral impingement (n=1). Resected lesser trochanter vs. Native lesser trochanter was evaluated on Hip range of motion and femoral head translation. Resection of the lesser trochanter increased hip range of motion and decreased femoral head translation by eliminating contact between the femur and pelvis in a cadaveric model.
