The postural function of the iliotibial tract.
Annals of the Royal College of Surgeons of England
|July 1, 1979
Summary
This study redefines the iliotibial tract, proposing a new role in posture and a novel bony effect on the hip bone. Its evolutionary presence supports upright posture evidence in fossils.
Area of Science:
- Anatomy
- Biomechanics
- Anthropology
Background:
- The iliotibial tract's anatomy and functions are not fully understood.
- Existing definitions lack comprehensive functional and evolutionary context.
Purpose of the Study:
- To redefine the iliotibial tract based on its anatomical and physical characteristics.
- To propose a new functional role for the iliotibial tract in human posture.
- To investigate its evolutionary presence and link to upright posture.
Main Methods:
- Anatomical and physical summarization of the iliotibial tract.
- Analysis of various standing postures, with a focus on a resting posture.
- Examination of the fossil record and anthropological evidence.
Main Results:
- A new definition and proposed role for the iliotibial tract in posture.
- Identification of a novel bony effect of the iliotibial tract on the hip bone.
- Tracing the iliotibial tract's presence in fossils, linking it to upright posture evolution.
Conclusions:
- The iliotibial tract plays a significant role in maintaining upright posture.
- Its evolutionary history is intertwined with human bipedalism.
- Further research into its biomechanical functions is warranted.
